Title: Systems and methods for blending solid-shell cosmetic ingredient capsules and blendable cosmetic ingredient capsules

Description:
RELATED APPLICATION 
     The present application claims priority under 35 U.S.C. § 119 to U.S. Provisional Patent Application No. 62/915,329, which is entitled “Appliance for Processing Skin Formulations,” was filed on Oct. 15, 2019, and the complete disclosure of which is hereby incorporated by reference. 
    
    
     FIELD OF THE DISCLOSURE 
     The present disclosure relates generally to devices and methods for producing cosmetic liquids from solid-shell cosmetic ingredient capsules, as well as to blendable cosmetic ingredient capsules that are configured to be heated and blended to produce the cosmetic liquids. 
     BACKGROUND OF THE DISCLOSURE 
     Cosmetics, such as creams, lotions, powders, mousses, gels, serums, balms, etc., may be applied to the skin, hair, nails, and/or other external body surfaces for various purposes, such as to beautify, enhance, soothe, moisturize, hydrate, and/or treat a specific issue or condition (e.g., acne). However, traditional cosmetics lose some of their efficacy because of the lengthy delay between the time of manufacturing and the time of use. In particular, many cosmetic products are mass produced in large quantities, packaged, stored at the manufacturer&#39;s facilities, shipped to retailers, stored on the retailers&#39; shelves, sold to consumers, stored at the consumers&#39; homes, and then dispensed, repeatedly, by the consumers over a prolonged period of time (e.g., months). This whole process, from manufacturing to use, can take many months or even years, and conventional cosmetics thus must contain sufficient preservatives to remain acceptable for consumer use during this time. When consumers have varying and/or multiple skin, hair, nail, etc. care or treatment needs, consumers thus must purchase and store multiple containers of cosmetics to accommodate these needs. These containers typically contain quantities of pre-made cosmetics to last for weeks or months when used daily, and thus much longer when only used periodically. Further, when applied to the skin, hair, nails, and/or other external body surfaces, the cosmetics may feel cold to the touch because they are often stored at room temperature in the consumer&#39;s home. 
     SUMMARY OF THE DISCLOSURE 
     Cosmetic blending devices configured to produce cosmetic liquids from solid-shell cosmetic ingredient capsules, solid-shell cosmetic ingredient capsules, methods of using the cosmetic blending devices to produce the cosmetic liquid, and methods of forming the solid-shell cosmetic ingredient capsules, are disclosed herein. 
     The cosmetic blending devices include a lid, a base, a blending element configured to blend the solid-shell cosmetic ingredient capsule, and a drive mechanism configured to actuate the blending element. The cosmetic blending device may include a thermal element configured to change a temperature within the enclosed blending chamber. The thermal element may melt the solid-shell cosmetic ingredient capsule. The lid and base may be adjusted between an open position and a closed position. In the open position, the lid and the base may permit a user to insert the solid-shell cosmetic ingredient capsule into the cosmetic blending device. In the closed position, the lid and the base may form and/or define an enclosed blending chamber that may be configured to retain the solid-shell cosmetic ingredient capsule and/or cosmetic liquid within the cosmetic blending device. The blending element may be included in the lid and may be configured to blend the solid-shell cosmetic ingredient capsule from above to produce the cosmetic liquid. 
     The solid-shell cosmetic ingredient capsule may include a shell defining an enclosed inner volume. The enclosed inner volume includes a cosmetic material. The cosmetic material may include a personal care ingredient and/or an active ingredient. When the active ingredient is included in the solid-shell cosmetic ingredient capsule, the shell additionally or alternatively may include the active ingredient. The shell may be configured to be solid at room temperature and may have a melting temperature of at least 32.2° C. When heated and blended, the cosmetic liquid may be formed from the entirety of the solid-shell cosmetic ingredient capsule. 
     Methods of using the cosmetic blending devices comprise placing the solid-shell cosmetic ingredient capsule into the cosmetic blending device, and blending the capsule to produce the cosmetic liquid. The methods additionally may include heating and/or melting the capsule. 
     Methods of forming the solid-shell cosmetic ingredient capsule comprise forming a portion of the shell, adding the cosmetic material to the portion of the shell, and forming the remaining portion of the shell such that the shell fully encloses the added cosmetic material. The shell may be formed in a mold, and the methods may include forming liquid shell material, dispensing this liquid shell material into the mold, and then solidifying the liquid shell material to form the shell.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
       FIGS.  1 - 15    provide examples of cosmetic blending devices  10 , of components and/or portions of cosmetic blending devices  10 , of solid-shell cosmetic ingredient capsules  300 , and/or of methods  400  and/or  450 , according to the present disclosure. In particular,  FIGS.  1 - 11    provide examples of cosmetic blending devices  10  and/or components or portions thereof,  FIGS.  1 ,  3   , and  12 - 13  provide examples of solid-shell cosmetic ingredient capsules  300 , and  FIGS.  14 - 15    provide examples of methods  400  and  450 . Elements that serve a similar, or at least substantially similar, purpose are labeled with like numbers in each of  FIGS.  1 - 15   , and these elements may not be discussed in detail herein with reference to each of  FIGS.  1 - 15   . Similarly, all elements may not be labeled in each of  FIGS.  1 - 15   , but reference numerals associated therewith may be utilized herein for consistency. Elements, components, and/or features that are discussed herein with reference to one or more of  FIGS.  1 - 15    may be included in and/or utilized with any of  FIGS.  1 - 15    without departing from the scope of the present disclosure. 
     In general, elements that are likely to be included in a particular embodiment are illustrated in solid lines, while elements that are optional are illustrated in dashed lines. However, elements that are shown in solid lines may not be essential and, in some embodiments, may be omitted without departing from the scope of the present disclosure. Dotted lines also may be used to show additional and/or alternate positions of components. Electrical connections between components are shown in dash-dot lines. 
     Cosmetic blending devices  10  are configured to heat and/or blend solid-shell cosmetic ingredient capsules  300  to produce a cosmetic liquid  330  (illustrated schematically in  FIGS.  1  and  4   ). Cosmetic liquid  330  may be a final cosmetic product (e.g., cream, oil, mousse, serum, etc.) that is configured to be directly applied to a user&#39;s skin, hair, nails, and/or other body surfaces. Cosmetic blending devices  10  may be configured to receive one or more of the solid-shell cosmetic ingredient capsules (e.g., a user may place one or more of the solid-shell cosmetic ingredient capsules into one of the cosmetic blending devices), heat and/or blend the one or more solid-shell cosmetic ingredient capsules to produce the cosmetic liquid, and/or present the cosmetic liquid to a user for extraction and direct body application. As described in more detail herein, such heated and/or blended cosmetic liquids may be fresher, more soothing, and/or more efficacious than conventional cosmetic products that are mass produced in large quantities. Such conventional cosmetic products are packaged in large, often plastic, containers containing a sufficient quantity of the cosmetic product for dozens if not hundreds of uses or doses, stored at the manufacturer&#39;s facility, transported to retailers, shelved at the retailers&#39; stores, sold to consumers, stored again at the consumer&#39;s home, and finally dispensed, repeatedly, by the consumer over a prolonged period of time (e.g., months). 
       FIG.  1    schematically illustrates examples of a cosmetic blending device  10  with examples of a solid-shell cosmetic ingredient capsule  300  positioned therein, according to the present disclosure. As depicted, cosmetic blending device  10  includes a housing  12  that defines the exterior of the device. Cosmetic blending device  10  further includes a lid  20  and a base  60  that are configured to be selectively adjusted between an open position and a closed position, with housing  12  thus defining at least eternal surfaces of the lid and the base. In the closed position, lid  20  and base  60  define an enclosed blending chamber  100 . In the open position, enclosed blending chamber  100  may be open (e.g., accessible to a user), and/or portions of lid  20  and base  60  that are inaccessible to a user in the closed position may be accessible to the user, thereby permitting a user to insert and/or remove cosmetic materials (e.g., solid-shell cosmetic ingredient capsule  300 , cosmetic liquid  330 , etc.) from blending chamber  100  and/or a portion of lid  20  and/or base  60 . The open and closed positions of lid  20  and base  60  additionally or alternatively may be referred to as the open and closed positions of cosmetic blending device  10  and/or the open and closed positions of blending chamber  100 . 
     Cosmetic blending device  10  also includes a blending element  22  that is configured to blend solid-shell cosmetic ingredient capsule  300  to produce cosmetic liquid  330  therefrom. Although  FIG.  1    illustrates lid  20  as including blending element  22 , it is within the scope of the present disclosure that base  60  additionally or alternatively may include blending device  22 . Thus, blending device  22  may be included in the lid and/or the base. Cosmetic blending device  10  also includes a thermal element  110  that is configured to change a temperature within enclosed blending chamber  100  and one or more actuators  118 . As an example, the one or more actuators  118  may include a drive mechanism  120  that may be configured to oscillate, reciprocate, rotate, pivot, translate, and/or otherwise move blending element  22 . As another example, the one or more actuators  118  may include a linear actuator  129  that may be configured to translate blending element  22  up and down within enclosed blending chamber  100 . 
     During operation of cosmetic blending device  10 , a user may open blending chamber  100 , place solid-shell cosmetic ingredient capsule  300  into blending chamber  100 , and close blending chamber  100 . In particular, a user may adjust lid  20  and base  60  to the open position to open blending chamber  100  and/or otherwise provide access to the blending chamber from external the cosmetic blending device, and place solid-shell cosmetic ingredient capsule  300  into and/or onto a top  62  of base  60  that may define a lower portion  102  of blending chamber  100 . The user then may adjust lid  20  and base  60  to the closed position to enclose blending chamber  100 . Cosmetic blending device  10  then may be activated to heat and blend solid-shell cosmetic ingredient capsule  300  to produce cosmetic liquid  330  therefrom. In particular, thermal element  110  may be configured to heat solid-shell cosmetic ingredient capsule  300  to at least the melting point of solid-shell cosmetic ingredient capsule  300 . Further, blending element  22  may be configured to rotate, oscillate, reciprocate, pivot, translate, and/or otherwise move within enclosed blending chamber  100  to blend solid-shell cosmetic ingredient capsule  300  to form cosmetic liquid  330 . 
     Cosmetic blending device  10  may be configured to form cosmetic liquid  330  solely from solid-shell cosmetic ingredient capsule  300 . Thus, cosmetic liquid  330  may be formed from only one solid-shell cosmetic ingredient capsule  300 , or optionally two or more solid-shell cosmetic ingredient capsules  300 . Said another way, solid-shell cosmetic ingredient capsule(s)  300  may form the entirety of cosmetic liquid  330 . No other components, ingredients, or other elements (e.g., other cosmetics, liquids, powders, gels, emulsifiers, etc.) may need to be added to form cosmetic liquid  330 . As examples, cosmetic liquid  330  may be formed solely from a single solid-shell cosmetic ingredient capsule  300 , at least two solid-shell cosmetic ingredient capsules  300 , at least three solid-shell cosmetic ingredient capsule  300 , and/or at least four solid-shell cosmetic ingredient capsules  300 . 
     Expressed in slightly different terms, the entirety of solid-shell cosmetic ingredient capsule  300  may form (i.e., may be used or consumed to form) cosmetic liquid  330 . Thus, cosmetic blending device  10  may be configured to blend all of solid-shell cosmetic ingredient capsule  300  (i.e., the entire capsule and all of its contents) to form cosmetic liquid  330 . In this way, blending element  22  may be configured to blend the entirety of solid-shell cosmetic ingredient capsule(s)  300 . By blending the entire capsule, waste products (e.g., packaging, liners, wrapping) may be reduced and/or eliminated, thereby reducing costs and environmental impact. 
     When cosmetic blending device  10  has completed heating and blending the solid-shell cosmetic ingredient capsule, a user may open blending chamber  100  to access cosmetic liquid  330 , which as discussed in more detail herein, then may be applied directly to the user&#39;s skin, hair, nails, and/or other body surfaces. 
     As used herein, cosmetic blending device  10  additionally or alternatively may be referred to as blending device  10 , mixing device  10 , cosmetic mixing device  10 , heat and blending device  10 , personal use cosmetic preparing device  10 , cosmetic activator  10 , and/or household cosmetic preparing device  10 . As used herein, solid-shell cosmetic ingredient capsule  300  additionally or alternatively may be referred to as packageless cosmetic ingredient capsule  300 , single-use cosmetic ingredient capsule  300 , unblended cosmetic product  300 , to-be-blended cosmetic product  300 , cosmetic liquid precursor  300 , not-skin-ready cosmetic product  300 , and/or blendable non-homogenous cosmetic product  300 . As used herein, enclosed blending chamber  100  additionally or alternatively may be referred to as blending chamber  100 , mixing chamber  100 , heating and blending chamber  100 , melting and blending chamber  100 , blending compartment  100 , and/or emulsification chamber  100 . As used herein, cosmetic liquid  330  additionally or alternatively may be referred to as liquid skin care formulation  330 , final cosmetic product  330 , skin-ready liquid cosmetic product  330 , ready-to-use liquid cosmetic product  330 , final product  330 , homogenous liquid cosmetic product  330 , and/or heated and blended liquid cosmetic product  330 . 
     Blending chamber  100  may be sized, configured, adapted, designed, and/or constructed to contain, retain, and/or hold solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . As examples, blending chamber  100  may define and/or have a volume of at least 1 milliliters (ml), at least 2 ml, at least 3 ml, at least 4 ml, at least 5 ml, at least 6 ml, at least 7 ml, at least 8 ml, at least 9 ml, at least 10 ml, at least 15 ml, at least 20 ml, at most 400 ml, at most 350 ml, at most 300 ml, at most 250 ml, at most 200 ml, at most 150 ml, at most 100 ml, at most 50 ml, at most 45 ml, at most 40 ml, at most 35 ml, at most 30 ml, at most 25 ml, at most 20 ml, at most 18 ml, at most 16 ml, at most 14 ml, at most 12 ml, at most 10 ml, and/or at most 8 ml. This volume does not include the volume of the blending element. Thus, the volume of the blending chamber is the volume of empty space in the blending chamber  100  when the blending chamber is empty (i.e., does not include solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 ). When solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  are included in blending chamber  100 , the volume of blending chamber  100  therefore includes the volume of the volume of solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . 
     As mentioned above, blending chamber  100  may be enclosed and/or formed when lid  20  and base  60  are in the closed position. Thus, the closed position is a position in which lid  20  and base  60  may fully enclose blending chamber  100 . In some examples, lid  20  and base  60  may be configured to provide a fluid seal between blending chamber  100  and the outside of cosmetic blending device  10  when the lid and the base are in the closed position. For example, lid  20  and base  60  may be in direct, sealing contact with one another in the closed position. Thus, lid  20  and base  60  may be configured to prevent leakage of any contents of solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  to the outside of cosmetic blending device  10  when the lid and the base are in the closed position. As such, blending chamber  100  may be and/or may define, an enclosed, empty space within cosmetic blending device  10 , such as between lid  20  and base  60 , when lid  20  and base  60  are in the closed position. As will be discussed in greater detail below, blending element  22  may extend into blending chamber  100  and occupy at least a portion of the enclosed empty space of the blending chamber when the lid and the base are in the closed position. In particular, blending element  22  may extend into blending chamber  100  from above solid-shell cosmetic ingredient capsule  300 , when solid-shell cosmetic ingredient capsule  300  is positioned in lower portion  102  of blending chamber  100 , such as bowl-shaped depression  64 . 
     In the open position, lid  20  and base  60  may not define enclosed blending chamber  100 . In particular, adjusting lid  20  and base  60  to the open position may open up blending chamber  100  and expose portions of lid  20  and base  60  that are inaccessible to a user when the lid and the base are in the closed position. For example, base  60  may include a top  62 , at least a portion of which may form lower portion  102  of blending chamber  100  when lid  20  and base  60  are in the closed position. However, in the open position, top  62  of base  60  may be directly accessible to a user. Similarly, lid  20  may include a bottom  40 , at least a portion of which may form and/or define an upper portion  104  of blending chamber  100  when lid  20  and base  60  are in the closed position. However, in the open position, bottom  40  of lid  20  may be directly accessible to a user. 
     Lid  20  and base  60  may be configured to be selectively adjusted between the open and closed positions by selectively repositioning lid  20  and base  60  relative to one another. For example, lid  20  and base  60  may be configured to be rotated, pivoted, and/or translated with respect to one another to adjust between the open and closed positions. 
     Cosmetic blending device  10  may include a coupling structure  130  that is configured to selectively permit lid  20  and base  60  to adjust between the open and closed positions. Additionally or alternatively, coupling structure  130  may be configured to selectively retain and/or lock lid  20  and base  60  in the closed position and/or selectively release lid  20  and base  60  to be transitioned to the open position. That is, coupling structure  130  may be configured to selectively restrict relative movement between lid  20  and base  60  and/or to hold lid  20  and base  60  in the closed position when lid  20  and base  60  are in the closed position, while still selectively permitting lid  20  and base  60  to adjust to the open position when desired by a user. Coupling structure  130  additionally or alternatively may be configured to permanently couple lid  20  and base  60  (even when lid  20  and base  60  are in the open position), while still permitting lid  20  and base  60  to adjust between the open and closed positions. 
     Coupling structure  130  may include a mechanical coupling structure  132  and/or a magnetic coupling structure  144  that is/are configured to bias, retain, keep, and/or otherwise hold lid  20  and base  60  in the closed position. Such a configuration may mitigate, and/or prevent un-commanded and/or otherwise undesirable adjustment towards and/or to the open position, such as during a blending cycle when blending element  22  is moving. In this way, coupling structure  130  may reduce and/or prevent spilling and/or leaking of the contents contained in blending chamber  100  (e.g., solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 ) and/or may restrict access to the blending chamber when blending element  22  is actuated or otherwise moving (e.g., spinning). In particular, the coupling structure  130  may exert a holding, or retaining, force that opposes and/or is greater than a maximum force exerted on lid  20  by drive mechanism  120  and/or blending element  22 . For example, when blending element  22  is configured to spin in a counterclockwise direction, drive mechanism  120  and/or blending element  22  may exert a countervailing clockwise torque on lid  20 . This countervailing clockwise torque may urge lid  20  to spin in a clockwise direction if nothing is holding lid  20  in place. However, in such examples, coupling structure  130  may exert a holding torque oriented in the opposite, counterclockwise direction that is greater than the clockwise torque exerted by drive mechanism  120  and/or blending element  22  on lid  20 , and therefore sufficient to hold lid  20  and base  60  in the closed position. 
     Additionally or alternatively, coupling structure  130  may be configured to be self-locking. That is, coupling structure  130  may be configured to utilize the force exerted on lid  20  by drive mechanism  120  and/or blending element  22  to bias lid  20  and base  60  towards the closed position. As an example, when blending element  22  is configured to spin within blending chamber  100  during a blending cycle, coupling structure  130  may be configured such that the force exerted by blending element  22  and/or drive mechanism  120  on lid  20  increases the holding force between lid  20  and base  60 . In particular, when blending element  22  is configured to spin in a counterclockwise direction, the coupling structure  130  may be configured to increase an amount of friction between lid  20  and base  60 . As one example, coupling structure  130  may include mating threads and/or grooves that may be configured to tighten lid  20  and/or base  60  in a rotational direction opposite to the rotational direction of blending element  22 . 
     Coupling structure  130  additionally or alternatively may be configured to selectively permit adjustment of lid  20  and/or base  60  towards the open position when desired. For example, a user may desire to adjust lid  20  and/or base  60  towards or to the open position before initiating a blending cycle in order to insert solid-shell cosmetic ingredient capsule  300  into cosmetic blending device  10 , and/or after a blending cycle has completed in order to remove, extract, and/or apply cosmetic liquid  330 . A blending cycle may comprise a single heating and blending sequence in which cosmetic blending device  10  produces cosmetic liquid  330  from solid-shell cosmetic ingredient capsule  300 . Thus, a blending cycle may begin when the cosmetic blending device initiates the heating and/or blending (after a user has inserted solid-shell cosmetic ingredient capsule  300  and adjusted the lid and the base to the closed position) and a blending cycle may terminate when the cosmetic blending device finishes the heating and/or blending and cosmetic liquid  330  is ready for extraction (i.e., when solid-shell cosmetic ingredient capsule  300  has been converted and/or transformed to cosmetic liquid  330  and/or when cosmetic blending device  10  alerts and/or notifies a user that the cosmetic liquid is ready for extraction). 
     A blending cycle may include one or more different periods, portions, and/or times. As an example, a blending cycle may include one or more of a warm-up period during which only the thermal element is powered on and the solid-shell cosmetic ingredient capsule is heated, a ramp-up period during which the drive mechanism is powered on and brought up to a desired rotational speed, a main blending sequence during which the drive mechanism operates at the desired rotational speed and where a majority of the mixing and blending occurs, and/or a cool down period where the drive mechanism is powered down and/or off and/or where the thermal element is adjusted (powered off and/or switched from a heating mode to a cooling mode) to cool the cosmetic liquid to a user-friendly temperature. Thus, different periods of a blending cycle may be categorized based on the processes performed during those periods. Stated slightly differently, a blending cycle may be broken down into one or more different periods, portions, and/or times based on differences/changes in the operations performed during those periods, portions, and/or times. 
     In some examples, coupling structure  130  may be configured to only release lid  20  and base  60  from the closed position (and thus permit adjustment towards the open position) when manually adjusted by a user. For example, coupling structure  130  may require that a user physically turn lid  20  and base  60  relative to one another in order to adjust lid  20  and base  60  towards the open position. As a further example, when coupling structure  130  is configured to be self-locking, coupling structure  130  may require that a user physically move (e.g., rotate, translate, and/or pivot) lid  20  and base  60  with enough force to overcome the frictional forces holding lid  20  and base  60  in the closed position. When coupling structure  130  is not configured to be self-locking, coupling structure may require that a user physically move lid  20  and base  60  relative to one another with a greater force than the maximum force exerted on lid  20  by blending element  22  and/or drive mechanism  120 . Additionally or alternatively, a user may have to disengage one or more locking fasteners (e.g., latches, pin and sockets, etc.) in order to release lid  20  and base  60  from the closed position. 
     Mechanical coupling structure  132  may be configured to selectively restrict relative movement (e.g., translation, rotation, and/or pivoting) between lid  20  and base  60  via mechanical forces (e.g., friction). In particular, mechanical coupling structure  132  may include a releasable locking structure  134  that is configured to restrict relative movement between lid  20  and base  60 . In particular, and as introduced above, releasable locking structure  134  may be configured to hold and/or retain lid  20  and base  60  in the closed position, and additionally or alternatively may be configured to selectively release lid  20  and base  60  when actuated by a user and/or only when actuated by a user. 
     Releasable locking structure  134 , when present, may include one or more of threads, friction fits, bayonet locks, pins and sockets, and/or other locking fasteners. For example, and as described in greater detail herein in connection with  FIGS.  3  and  9 - 10   , when releasable locking structure  134  includes a threaded engagement between lid  20  and base  60 , lid  20  and base  60  may each include threads and/or grooves that are configured to mate with one another. As an example, both lid  20  and base  60  may include multiple threads (each including ridges and grooves). In another example, the releasable locking structure  134  may include only one ridge and one groove. In such examples, only one of lid  20  or base  60  may include the ridge, and the other may include the mating groove. For example, an exterior-facing surface of a top edge  76  of base  60  may include a set of ridges, and an interior-facing surface of a bottom edge  44  of lid  20  may include a set of mating grooves. 
     The threaded engagement may be configured to tighten (e.g., lid  20  may be configured to thread farther onto base  60 ) in a first rotational direction (e.g., clockwise) and to loosen in a second rotational direction opposite the first rotational direction. Thus, lid  20  may be threaded onto base  60  to adjust lid  20  and base  60  to the closed position by rotating lid  20  in the first rotational direction. Once threaded onto base  60 , friction between the mating threads and/or grooves in lid  20  and base  60  may hold lid  20  and base  60  in the closed position. As mentioned above, a rotational direction of blending element  22  additionally or alternatively may bias lid  20  towards the closed position. In particular, blending element  22  may spin in a rotational direction that is opposite the first rotational direction (e.g., the tightening direction of the threaded engagement). For example, when the threaded engagement is configured to tighten in a clockwise direction, blending element  22  may be configured to spin in the counterclockwise direction, and vice versa. In this way, coupling structure  130  may be self-locking (i.e., the forces exerted on lid  20  by drive mechanism  120  and/or blending element  22  may be configured to bias lid  20  and base  60  towards the closed position), thereby reducing and/or eliminating the need for additional locking and/or holding structures. In particular, the force exerted on lid  20  by blending element  22  and/or drive mechanism  120  may be sufficient by itself to hold lid  20  and base  60  in the closed position during a blending cycle. 
     As described above, bayonet locks, pins and sockets, and/or other locking fasteners additionally or alternatively may be included in the releasable locking structure  134  to help keep lid  20  and base  60  locked in the closed position. As one example, releasable locking structure  134  may include a latch that is configured to be manually adjusted between a locked position and an unlocked position by a user. When in the locked position, the latch may restrict lid  20  and base  60  from being adjusted from the closed position towards and/or to the open position. Once in the unlocked position, the latch may permit lid  20  and base  60  to be adjusted from the closed position to the open position. As another example, the mechanical fastener may comprise a flexible pin-and-socket arrangement that is configured to be manually adjusted between a locked position and an unlocked position by a user. In particular, the pin may be biased (e.g., via a spring) to an extended position, in which the pin-and-socket arrangement is in the locked position. In this locked position (in which the pin is in the extended position), the pin may extend through the socket to lock lid  20  and base  60 . A user may unlock the flexible pin-and-hole arrangement by pushing on the pin such that it disengages with the socket, and then rotating lid  20  and base  60 . 
     Coupling structure  130  additionally or alternatively may include magnetic coupling structure  144 . Magnetic coupling structure  144  may be configured to selectively restrict relative movement (e.g., translation, rotation, and/or pivoting) between lid  20  and base  60  and/or bias lid  20  and base  60  to the closed position via magnetic forces. In particular, lid  20  and base  60  may each include a magnet and/or ferromagnetic material. As one example, both lid  20  and base  60  may include magnets. In some such examples, lid  20  and/or base  60  additionally may include ferromagnetic material. As another example, lid  20  may include a magnet and base  60  may include a ferromagnetic material. As yet another example, lid  20  may include a ferromagnetic material and base  60  may include a magnet. In all examples, the magnets and/or ferromagnetic material in lid  20  may be configured to be magnetically attracted to other magnets and/or ferromagnetic material in base  60 , such that lid  20  and base  60  are attracted to one another. The magnets and/or ferromagnetic materials in lid  20  may be at their closest approach to the magnets and/or ferromagnetic materials in base  60  when lid  20  and base  60  are in the closed position, and thus may exert a maximum attractive magnetic force when lid  20  and base  60  are in the closed position. This attractive magnetic force may help bias, retain, hold, and/or keep lid  20  and base  60  in the closed position. 
     Coupling structure  130  may be configured such that, when adjusted to the open position, lid  20  and base  60  may completely detach from one another, as illustrated in  FIG.  3   . In other examples, lid  20  and base  60  may remain attached and/or coupled to one another in the open position. In particular, coupling structure  130  may include a permanent coupling structure  140  that may be configured to permanently couple lid  20  and base  60  while permitting lid  20  and base  60  to be selectively adjusted between the open and closed positions. As one example, permanent coupling structure  140  may include a tether. As another example, permanent coupling structure  140  may include a hinge  141 . Hinge  141  may include two pivoting flanges, with a first flange  142  connected to lid  20 , and a second flange  143  connected to base  60 . 
     In yet further examples, lid  20  and/or base  60  may not be selectively repositioned when being adjusted between the open and closed positions, however cosmetic blending device  10  may nonetheless include an access structure that is configured open and close to provide a user access to blending chamber  100 . As one example, lid  20  and/or base  60  may include a door that may configured to be selectively opened to access blending chamber  100 . 
     As discussed above, blending chamber  100  is defined by lid  20  and base  60 . That is, lid  20  and base  60  may define the walls and/or boundaries of blending chamber  100 . In particular, at least a portion of top  62  of base  60  may define and/or form lower portion  102  of blending chamber  100 , and at least a portion of bottom  40  of lid  20  may define and/or form upper portion  104  of blending chamber  100 . 
     Top  62  of base  60  may be sized, configured, adapted, designed, and/or constructed to contain, retain, receive, and/or hold solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . In particular, top  62  of base  60  may include a bowl-shaped depression  64  that may be sized, configured, adapted, designed, and/or constructed to contain, retain, receive, and/or hold solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . Specifically, bowl-shaped depression  64  may be larger in volume than solid-shell cosmetic ingredient capsule  300 . As examples, bowl-shaped depression  64  may have a volume (may be configured to contain, hold and/or otherwise retain a volume of fluid without the fluid overflowing) of least 0.5 ml, at least 0.75 ml, at least 1 ml, at least 1.5 ml, at least 2 ml, at least 2.5 ml, at least 3 ml, at least 3.5 ml, at least 4 ml, at least 4.5 ml, at least 5 ml, at least 5.5 ml, at least 6 ml, at least 6.5 ml, at least 7 ml, at least 7.5 ml, at least 8 ml, at least 8.5 ml, at least 9 ml, at least 9.5 ml, at least 10 ml, at most 25 ml, at most 20 ml, at most 18 ml, at most 16 ml, at most 15 ml, at most 14 ml, at most 13 ml, at most 12 ml, at most 11 ml, at most 10 ml, at most 9 ml, at most 8 ml, at most 7 ml, at most 6 ml, at most 5 ml, at most 4 ml, at most 3 ml, and/or at most 2 ml. Thus, a user may place solid-shell cosmetic ingredient capsule  300  into and/or onto top  62  of base  60  and/or bowl-shaped depression  64  prior to heating and blending the solid-shell cosmetic ingredient capsule, and the user may extract cosmetic liquid  330  from top  62  of base  60  and/or bowl-shaped depression  64  after the cosmetic blending device heats and blends the solid-shell cosmetic ingredient capsule to form cosmetic liquid  330 . 
     Bowl-shaped depression  64  may be and/or define a depression, cavity, concavity, and/or indentation on top  62  of base  60 . In particular, bowl-shaped depression  64  may include a bottom  66  and sidewalls  68 , and bottom  66  may be recessed relative to a top edge  76  of base  60 . Sidewalls  68  may be angled outward from bottom  66  of bowl-shaped depression  64  such that the cross-sectional area of bowl-shaped depression  64  may be greater nearer top edge  76  of base  60  than bottom  66  of bowl-shaped depression  64 . However, in other examples, sidewalls  68  may be substantially straight (i.e., orthogonal to bottom  66 ). A height of bowl-shaped depression  64  (i.e., a distance between bottom  66  and top edge  76 ) may be at least 0.5 centimeters (cm), at least 1 cm, at least 1.5 cm, at least 2 cm, at least 2.5 cm, at least 3 cm, at most 6 cm, at most 5 cm, at most 4 cm, at most 3.5 cm, at most 3 cm, and/or at most 2.5 cm. Further, a diameter of bottom  66  of bowl-shaped depression  64  may be at least 0.4 cm, at least 0.6 cm, at least 0.8 cm, at least 1 cm, at least 1.2 cm, at least 1.4 cm, at least 1.6 cm, at least 1.8 cm, at least 2 cm, at most 6 cm, at most 5 cm, at most 4 cm, at most 3 cm, at most 2.4 cm, and at most 2.2 cm, and/or at most 2 cm. Although bottom  66  is described as having a diameter, bowl-shaped depression  64  may have any suitable cross-sectional shape, with examples including, elliptical, rectangular, square, triangular, pentagonal, hexagonal, and/or other regular or irregular polygonal shapes. When bottom  66  has a non-circular shape, the above diameters of bottom  66  may be a minimum or maximum dimension (e.g., axis) of bottom  66  of bowl-shaped depression  64 . 
     In this way, blending chamber  100 , and more specifically, bowl-shaped depression  64 , may be configured to hold, retain, and/or contain the entirety of solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . Further, cosmetic blending device  10  may be configured to heat and/or blend the entirety of solid-shell cosmetic ingredient capsule  300 . In particular, solid-shell cosmetic ingredient capsule  300  may be placed into blending chamber  100  without any packaging, and cosmetic blending device  10  may be configured to heat and/or blend the entirety of solid-shell cosmetic ingredient capsule  300  to form cosmetic liquid  330  therefrom. Thus, after the heating and/or blending, all of the solid-shell cosmetic ingredient capsule may be transformed to cosmetic liquid  330 . That is, the entirety of solid-shell cosmetic ingredient capsule  300  may form the cosmetic liquid. Stated another way, the entirety of cosmetic liquid  330  may be formed from solid-shell cosmetic ingredient capsule. This may reduce and/or eliminate the need for single-use packaging, containers, disposable wrappings, and/or other waste products, thereby providing a more environmentally friendly and less wasteful cosmetic product. 
     Bottom  66  of bowl-shaped depression  64  may be flat and/or planar and/or at least substantially flat and/or planar. Although bottom  66  of bowl-shaped depression  64  may be perfectly flat and/or planar in some examples, it should be appreciated that it may be difficult, impractical, and/or impossible, to achieve a perfectly flat and/or planar surface in all examples. Thus, the above recitation that bottom  66  of bowl-shaped depression  64  may be at least substantially flat and/or planar should be interpreted to mean that the bottom of bowl-shaped depression  64  is intended to be, or is effectively, flat and/or planar while recognizing that it may not be practical, possible, or at least economical, to ensure that the bottom is exactly flat and/or planar in all systems, at all times, and/or under all circumstances. 
     However, in other examples, bottom  66  of bowl-shaped depression  64  may be curved, concave, convex, arcuate, and/or otherwise non-planar. Additionally or alternatively, bottom  66  of bowl-shaped depression  64  may include one or more indentations, concavities, and/or depressions. As one such example, bottom  66  of bowl-shaped depression  64  may include a central indentation. 
     Bowl-shaped depression  64  may be configured to readily transfer thermal energy from thermal element  110  to blending chamber  100 , solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . In particular, bowl-shaped depression  64  may be constructed from a thermally conductive material and/or a material that has a relatively low specific heat capacity. For example, bowl-shaped depression  64  may be constructed from a material having a thermal conductivity of at least 50 Watts per meter-Kelvin (W/(m·K)), at least 100 W/(m·K), at least 150 W/(m·K), and/or at least 200 W/(m·K). Additionally or alternatively, bowl-shaped depression  64  may be constructed from a material that has a specific heat capacity of at most 1100 Joules per kilogram-Kelvin (J/(kg K)), at most 1000 J/(kg K), and/or at most 900 J/(kg K). As one example, bowl-shaped depression  64  may be constructed from aluminum. In other examples, bowl-shaped depression  64  may be constructed from a different metal such as copper and/or a metal alloy such as stainless steel. 
     Additionally or alternatively, a thickness of bowl-shaped depression  64 , including a thickness of bottom  66  and/or sidewalls  68 , may be sized, configured, adapted, and/or constructed to promote and/or optimize thermal transfer from thermal element  110  to blending chamber  100 , solid-shell cosmetic ingredient capsule  300 , and/or cosmetic liquid  330 . As examples, bowl-shaped depression  64  may be sized to have a thickness of at least 0.05 cm, at least 0.075 cm, at most 0.1 cm, at most 0.125 cm, at most 0.15 cm, at most 0.2 cm, and/or at most 0.25 cm, and/or at most 0.4 cm. However, the thickness of bowl-shaped depression  64  may be adjusted based on one or more of the strength, formability, specific heat capacity, thermal conductivity, and density of the material. For example, since stainless steel has a lower thermal conductivity than aluminum, bowl-shaped depression  64  may be thinner when constructed from stainless steel than when constructed from aluminum to provide adequate thermal transfer. 
     Configuring bowl-shaped depression  64  to readily transfer thermal energy may result in shorter melt times (i.e., solid-shell cosmetic ingredient capsule  300  may be liquefied more quickly), thereby reducing the duration of the heating and/or blending of the solid-shell cosmetic ingredient capsule. Further, configuring bowl-shaped depression  64  to readily transfer thermal energy may provide more even and homogenous heating of the solid-shell cosmetic ingredient capsule and the resulting cosmetic liquid. 
     Bowl-shaped depression  64  may include a coating on an external surface  69  that is configured to prevent degradation of bowl-shaped depression  64 . For example, the coating may be configured to prevent and/or restrict chemical reactions, corrosion, and/or erosion of external surface  69 . Additionally or alternatively, the coating may be configured to color external surface  69 . The coating also or alternatively may be configured to facilitate cleaning and/or removal of the cosmetic liquid. The coating may be configured to be thin enough (e.g., less than 2 mm) to not reduce, mitigate, and/or otherwise interfere with thermal conduction. Example coatings include one or more of anodized coatings, powder coatings, plated coatings, and ceramic coatings. External surface  69  (on which the coating may be applied) faces blending chamber  100 , and may directly interface with solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . That is, when a user places solid-shell cosmetic ingredient capsule  300  into blending chamber  100 , the solid-shell cosmetic ingredient capsule may sit on and/or directly contact external surface  69 . 
     Cosmetic blending device  10  additionally and/or alternatively may include a cosmetic ingredient receptacle  150  that optionally may be positioned between external surface  69  and solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . Cosmetic ingredient receptacle  150  may be configured to not only retain, contain, and/or hold solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 , but also may be configured, adapted, and/or designed to be selectively removed from base  60 . In particular, cosmetic ingredient receptacle  150  may be configured, sized, adapted, designed, and/or constructed to fit within and/or line bowl-shaped depression  64 . For example, the cosmetic ingredient receptacle may include one or more of a tray, cup, dish, flexible liner, etc. Thus, a user may selectively insert solid-shell cosmetic ingredient capsule  300  into cosmetic ingredient receptacle  150 , and/or may selectively remove cosmetic liquid  330  from cosmetic ingredient receptacle  150 . Additionally or alternatively, a user may selectively remove cosmetic ingredient receptacle  150  from cosmetic blending device  10  before removing cosmetic liquid  330  from cosmetic ingredient receptacle  150  and/or may selectively remove cosmetic ingredient receptacle  150  to insert solid-shell cosmetic ingredient capsule  300 , and then may place cosmetic ingredient receptacle  150  back in cosmetic blending device  10 . 
     Cosmetic ingredient receptacle  150  may be reusable, and a user may repeatedly remove and/or replace cosmetic ingredient receptacle  150  to insert new solid-shell cosmetic ingredient capsules and/or remove cosmetic liquids. After placing solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  into cosmetic ingredient receptacle  150 , a user may initiate the heating and blending cycle and/or the cosmetic blending device may automatically initiate the heating and blending cycle. After the heating and blending cycle, a user may remove cosmetic ingredient receptacle  150  from cosmetic blending device  10  to extract cosmetic liquid  330 . 
     In some examples, cosmetic ingredient receptacle  150 , when present, may be separate from solid-shell cosmetic ingredient capsule  300 . That is, solid-shell cosmetic ingredient capsule  300  and cosmetic ingredient receptacle  150  may not be packaged together. As such, solid-shell cosmetic ingredient capsule  300  may need to be placed into cosmetic ingredient receptacle  150  prior to heating and/or blending solid-shell cosmetic ingredient capsule  300 . However, in other examples, solid-shell cosmetic ingredient capsule  300  may be packaged with cosmetic ingredient receptacle  150 . As an example, cosmetic ingredient receptacle  150  may form at least a portion of the packaging of the solid-shell cosmetic ingredient capsule  300  and/or otherwise may be configured to protect solid-shell cosmetic ingredient capsule  300  from damage during shipping, handling, and storage. In such examples, a user may not need to place solid-shell cosmetic ingredient capsule  300  into cosmetic ingredient receptacle  150  prior to heating and/or blending solid-shell cosmetic ingredient capsule  300  because solid-shell cosmetic ingredient capsule  300  already may be included within the cosmetic ingredient receptacle. 
     In all of the above examples, cosmetic ingredient receptacle  150  may be configured to store, or contain, cosmetic liquid  330  produced by cosmetic blending device  10 . As an example, after heating and/or blending the solid-shell cosmetic ingredient capsule, a user may remove cosmetic ingredient receptacle  150  (and cosmetic liquid  330  contained therein) from the cosmetic blending device, and may extract the cosmetic liquid from the cosmetic ingredient receptacle as desired over a period of time (at a desired rate, rather than all at once). Utilizing such cosmetic ingredient receptacles may enable a user to produce multiple cosmetic liquids  330 . That is, the cosmetic blending device may be operated repeatedly (i.e., over multiple cycles) to produce multiple cosmetic liquids  330  that may each be stored in separate cosmetic ingredient receptacles  150 . Thus, cosmetic ingredient receptacle  150  may allow a user to store the cosmetic liquid for later use, and/or to prepare multiple cosmetic liquids in a short period of time to be used concurrently. 
     Additionally or alternatively, cosmetic ingredient receptacle  150  may enable easier cleaning of the cosmetic blending device. In particular, because the cosmetic ingredient receptacle may hold all of the cosmetic liquid, a user may not need to clean bowl-shaped depression  64  as often in between blending cycles as a user does if cosmetic ingredient receptacle  150  is omitted. Further, because cosmetic ingredient receptacle  150  may be removable, it may be easier to rinse and clean than bowl-shaped depression  64 . 
     In yet further examples, cosmetic ingredient receptacle  150  may be omitted, but bowl-shaped depression  64  may be configured to be selectively removed and/or coupled to base  60 . For example, bowl-shaped depression  64  and/or base  60  may include depression coupling structures  152  that may be configured to selectively couple and decouple base  60  and bowl-shaped depression  64 . When coupled to base  60 , cosmetic ingredient receptacle  150  may be configured to not move during a blending cycle, and may only move between blending cycles, when desired by a user (i.e., may require an external, user-provided force to decouple from base  60 ). As one such example, depression coupling structures  152  may include a flexible snap-fit arrangement in which bowl shaped depression  64  may clip into and out of base  60 . Additionally or alternatively, depression coupling structures  152  may include any other coupling structures that are suitable to selectively couple and decouple base  60  and bowl-shaped depression  64 , such as any of the example coupling structures of coupling structure  130  discussed above. 
     Blending element  22  extends into blending chamber  100  when lid  20  and base  60  are in the closed position. For example, blending element  22  may extend into blending chamber  100  from lid  20  when lid  20  and base  60  are in the closed position. In particular, blending element  22  may include a shaft  24  that extends into blending chamber  100 . When blending element  22  is included in the lid, shaft  24  may extend downward, below at least a portion of bottom  40  of lid  20  when lid  20  and base  60  are in the closed position. In particular, bottom  40  of lid  20  may include a cavity  42  that is recessed from bottom edge  44  of lid  20 , and blending element  22  may extend below at least the cavity. In the description herein, the terms up, down, above, and below may be used to describe the relative positioning of components of cosmetic blending device  10  along a vertical axis  250 . Thus, components described as being above one or more other components may be positioned at a more positive position, further along vertical axis  250 , and vice versa. 
     Blending element  22  may extend into lower portion  102  of blending chamber  100  toward bottom  66  of bowl-shaped depression  64 , and/or even into contact with bottom  66  of bowl-shaped depression  64 . In particular, blending element  22  may extend into blending chamber  100  from above solid-shell cosmetic ingredient capsule  300 , when solid-shell cosmetic ingredient capsule  300  is positioned in bowl-shaped depression  64 . Thus, blending element  22  may blend solid-shell cosmetic ingredient capsule  300  from above. In the description herein, the terms above and below may be used to reference the relative positioning of components with respect to gravity. Thus, the blending element  22  may be above solid-shell cosmetic ingredient capsule  300  with respect to a direction of the gravitational force of Earth (i.e., at least a portion of blending element  22  and lid  20  may be farther from Earth&#39;s center of mass than base  60 ). When cosmetic blending device  10  is positioned on a surface (e.g., table, countertop, etc.) base  60  may be positioned below lid  20 , and thus it is base  60  that may be placed on and/or directly interface with the surface. Thus, cosmetic blending device  10  may be positioned in the orientation depicted in  FIG.  2   , for example, when heating and/or blending the solid-shell cosmetic ingredient capsule. 
     In some examples, blending element  22  may extend to within close proximity of bottom  66  of bowl-shaped depression  64 , but may not actually touch bottom  66  of bowl shaped depression. In particular, a bottom  26  of blending element  22  and/or shaft  24  may be separated from (spaced above) bottom  66  of bowl-shaped depression  64  by at least at least 0.5 millimeters (mm), at least 1 mm, at least 1.5 mm, at least 2 mm, at least 2.5 mm, at least 3 mm, at least 3.5 mm, at least 4 mm, at least 4.5 mm, at least 5 mm, at most 10 mm, at most 9 mm, at most 8 mm, at most 7 mm, and/or at most 6 mm, when lid  20  and base  60  are in the closed position. Spacing blending element  22  away from bottom  66  of bowl-shaped depression  64  may reduce contact friction (e.g., rubbing) between blending element  22  and bowl-shaped depression  64 , thereby reducing potential degradation of these components. Further, spacing blending element  22  from bottom  66  of bowl-shaped depression  64  may facilitate better blending (e.g., more homogenous, even blending) of solid-shell cosmetic ingredient capsule  300  because the space between the blending element and the bowl-shaped depression may increase turbulence of heated fluid below the blending element, and may limit and/or reduce the formation of large chunks of solid cosmetic material. In particular, the space between the blending element and the bowl-shaped depression may reduce an amount of cosmetic material that is pushed between cutting edges of the blending element. However, in other examples, blending element  22  may extend all the way to bottom  66  of bowl-shaped depression  64  such that it physically contacts bottom  66  when lid  20  and base  60  are in the closed position. 
     Further, shaft  24  may be configured to extend far enough into blending chamber  100 , (e.g., far enough from lid  20  towards bottom  66  of bowl-shaped depression  64 ), to make contact with solid-shell cosmetic ingredient capsule  300  when lid  20  and base  60  are in the closed position. In some examples, bottom  26  of blending element  22  may be configured to crush, compress, flatten, deform, squash, splinter, puncture, and/or otherwise break up solid-shell cosmetic ingredient capsule  300  when lid  20  and base  60  are adjusted to the closed position. In particular, when separated from bottom  66  of bowl-shaped depression  64 , the distance separating bottom  26  of blending element  22  from bottom  66  of bowl-shaped depression  64  may be less than one or more of a height, width, length, and/or radius of solid-shell cosmetic ingredient capsule  300 . Thus, blending element  22  may compress solid-shell cosmetic ingredient capsule  300  between bottom  26  of blending element  22  and bottom  66  of bowl-shaped depression  64  when the cosmetic blending device is adjusted from the open position to the closed position. 
     As mentioned above, bottom  26  of blending element  22  may be configured to facilitate piercing, crushing, squashing, splintering, puncturing, and/or otherwise breaking of solid-shell cosmetic ingredient capsule  300 . As one example, bottom  26  may be flat and may be particularly suitable for crushing, squashing, and/or compressing the solid-shell cosmetic ingredient capsule. In particular, when bottom  26  is flat, it may facilitate better blending (e.g., more homogenous, even blending) of solid-shell cosmetic ingredient capsule  300  because the flat bottom may not only puncture solid-shell cosmetic ingredient capsule  300  via the applied compressive force, but it also may hold solid-shell cosmetic ingredient capsule  300  in position and restrict solid-shell cosmetic ingredient capsule  300  from moving around within blending chamber  100  and/or otherwise avoiding the blending element. As another example, bottom  26  may be substantially flat, but additionally may include a pointed tip that may be particularly suitable for initially piercing the solid-shell cosmetic ingredient capsule. In yet further examples, bottom  26  may be curved, pointed, convex, and/or may include one or more projections, fins, cutting edges, etc. 
     As described above, blending element  22  is configured to blend solid-shell cosmetic ingredient capsule  300  in blending chamber  100 . Thus, blending element  22  additionally or alternatively may include cutting edges  28 . Cutting edges  28  may be configured to cut, slice, mix, blend, liquefy, and/or homogenize solid-shell cosmetic ingredient capsule  300 . Cutting edges  28  include at least one cutting edge  28 , at least two cutting edges  28  (e.g., a forked design), at least three cutting edges  28 , at least four cutting edges  28 , at least five cutting edges  28 , at least six cutting edges  28 , at least seven cutting edges  28 , at least eight cutting edges  28 , at most eight cutting edges  28 , at most seven cutting edges  28 , at most six cutting edges  28 , at most five cutting edges  28 , and/or at most four cutting edges  28 . Regardless of the number of cutting edges included on blending element  22 , each cutting edge  28  may comprise one or more of a propeller, blade, fin, and/or other sharp and/or curved surface suitable for blending solid-shell cosmetic ingredient capsule  300 . As used herein, cutting edges  28  additionally or alternatively may be referred to as curved cutting edges  28 , blades  28 , propeller blades  28 , angled fins  28 , and/or forked cutting edges  28 . 
     Cutting edges  28  may be coupled to and/or integrally formed with shaft  24 , and may extend outward and/or upward from shaft  24 . In particular, cutting edges may extend upward towards lid  20  and away from bottom  26  of blending element  22 . As one example, cutting edges  28  may comprise propeller-like blades that may define a pitch angle relative to shaft  24 . Additionally or alternatively, one or more of the cutting edges may extend downward, towards base  60 . As one example, blending element  22  may include a forked cutting edge (i.e., two cutting edges). In such examples, one of the cutting edges may angle downwards, while the other cutting edge may angle upwards, such as is illustrated in  FIG.  11   . 
     Regardless of the blade orientation, one or more of the cutting edges may be substantially flush with bottom  26  of blending element  22  and/or may form a portion of bottom  26  of blending element  22  and may extend upwards from bottom  26  of blending element  22 . However, in other examples, the cutting edges may be positioned above bottom  26  of blending element  22 . As one example, shaft  24  may extend below cutting edges  28  and alone may define bottom  26  of blending element  22 . Said another way, the cutting edges may be set above the bottom of shaft  24 . 
     Blending element  22  (e.g., shaft  24  and/or cutting edges  28 ) may be constructed from a rigid and/or elastomeric plastic. Additionally or alternatively, blending element  22  may be constructed from a thermally conductive material and/or a material that has a relatively low specific heat capacity. For example, blending element  22  may be constructed from a material having a thermal conductivity of at least 50 W/(m·K), at least 100 W/(m·K), at least 150 W/(m·K), and/or at least 200 W/(m·K). Additionally or alternatively, blending element  22  may be constructed from a material that has a specific heat capacity of at most 1100 J/(kg K), at most 1000 J/(kg K), and/or at most 900 J/(kg K). As one example, blending element  22  may be constructed from aluminum. In other examples, blending element  22  may be constructed from a different metal, such as copper and/or a metal alloy, such as stainless steel. In yet further examples, blending element  22  may be constructed from a combination of different materials. As one example, portions of blending element  22  (e.g., shaft  24 ) may be constructed from a plastic, while cutting edges  28  may be constructed from a metal and/or a metal alloy. Further, blending element  22  may include one or more of hollow interior regions, apertures, holes, cut-outs, indentations, and/or voids  30  (as illustrated schematically in dashed lines in  FIG.  11   ) to reduce a weight of the blending element, and therefore reduce an amount of force required to spin blending element  22 . 
     Blending element  22  may include a coating, similar to bowl-shaped depression  64 . Thus, the coating may be configured prevent degradation of blending element  22 , to color external blending element  22 , and/or to facilitate cleaning and/or removal of cosmetic liquid  330 . In some examples, the color of the coating may be configured to at least substantially match the color of the bowl-shaped depression  64 . Example coatings include one or more of anodized coatings, powder coatings, plated coatings, and ceramic coatings. 
     Constructing blending element  22  from a thermally conductive material and/or a material having a relatively low specific heat capacity may facilitate more even and complete heating and/or blending of solid-shell cosmetic ingredient capsule  300 . In particular, blending element  22  may distribute more thermal energy to solid-shell cosmetic ingredient capsule  300  via cutting edges  28  and/or shaft  24  when constructed from a thermally conductive material, which in turn may facilitate more even and complete heating and/or blending of solid-shell cosmetic ingredient capsule  300 , resulting in a more homogenous cosmetic liquid  330 . Stated another way, constructing blending element  22  from a thermally conductive material may liquefy solid-shell cosmetic ingredient capsule  300  faster and/or ensure that solid-shell cosmetic ingredient capsule  300  completely melts during the heating and blending cycle. 
     Including the blending element  22  in the lid as opposed to the base may increase ease of cleaning the cosmetic blending device, reduce user hazards, and/or increase blending effectiveness. In particular, cosmetic liquid  330  may be at least partially and/or entirely contained within bowl-shaped depression  64 . Thus, when blending element  22  is included in lid  20 , the blending element may not interfere with the dispensing, extracting, and/or removal of cosmetic liquid  330  from bowl-shaped depression  64 . This may reduce risk of injury to a user if a user reaches into the bowl-shaped depression  64  to extract the cosmetic liquid. Further, it may enable easier cleaning of the cosmetic liquid  330  from the bowl-shaped depression in-between blending cycles. In some examples, blending element  22  may be configured to be selectively detached from lid  20 . In some such examples, blending element  22  may be selectively coupled to lid  20  via a coupling structure, such as any one or more of the example coupling structures discussed above of coupling structure  130 . However, in other examples, blending element  22  may not be detachable, and may be permanently coupled to, and/or included within, lid  20 . A removable blending element may be easier to clean than one that is permanently attached to the lid. 
     Additionally or alternatively, the blending element  22  may blend the solid-shell cosmetic ingredient capsule and/or cosmetic liquids more evenly when included in the lid as opposed to the base. For example, when blending element  22  is included in base  60 , gravity may pull pieces of solid-shell cosmetic ingredient capsule towards the shaft, thereby lodging these pieces in-between the cutting edges of the blending element. These chunks may not blend with the rest of the cosmetic liquid, resulting in a chunkier, less homogenous final product. However, by including the blending element in the lid, gravity may naturally pull pieces of the solid-shell cosmetic ingredient capsule away from the shaft of the blending element, and may keep a larger proportion of the solid-shell cosmetic ingredient capsule at the tips of the curved cutting edges, where the cutting edges are most effective. Stated differently, including the blending element in the lid may inhibit chunks of the solid-shell cosmetic ingredient capsule from developing and becoming stuck in-between the cutting edges of the blending element and may encourage more even, homogenous blending of solid-shell cosmetic ingredient capsule  300 . 
     Thermal element  110  may be configured to change a temperature within blending chamber  100 , and more specifically, may be configured to change a temperature of solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . As one example, thermal element  110  may be configured to heat (i.e., increase the temperature of) solid-shell cosmetic ingredient capsule  300 . In particular, thermal element  110  may be configured to heat solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  to, and/or above, the melting temperature of the solid-shell cosmetic ingredient capsule. As examples, thermal element  110  may be configured to heat solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  in blending chamber  100  to at least 27° C., at least 28° C., at least 29° C., at least 30° C., at least 31° C., at least 32.2° C., at least 33° C., at least 34° C., at least 35° C., at least 36° C., at least 37° C., at least 38° C., at most 62° C., at most 61° C., at most 60° C., at most 59° C., at most 58° C., at most 56° C., at most 54° C., at most 52° C., at most 50° C., at most 49° C., and/or at most 48° C. Additionally or alternatively, and as discussed above, thermal element  110  may be configured to heat blending element  22  since blending element  22  is included in blending chamber  100 . In some such examples, thermal element  110  may be included in blending element  22 . 
     Thermal element  110  may comprise at least one thermal element  110 , at least two thermal elements  110 , at least three thermal elements  110 , at least four thermal elements  110 , at least five thermal elements  110  and/or at least six thermal elements  110  that may be positioned at one or more positions around the exterior of blending chamber  100 . As one example, thermal element  110  may be positioned around an exterior of lower portion  102  of blending chamber  100  (interior of base  60 ). As illustrated in  FIG.  1   , thermal element  110  may be positioned around an outside of blending chamber  100  (i.e., within lid  20  and base  60 ) to transfer thermal energy to blending chamber  100 . In particular, thermal element  110  may be positioned around an outside of lower portion  102  of blending chamber  100 . For example, thermal element  110  may be positioned around bottom  66  of bowl-shaped depression  64  and/or sidewalls  68  of bowl-shaped depression  64 . More specifically, thermal element  110  may be in direct, interfacing contact with an internal surface  70  of bowl-shaped depression  64  and/or may be coupled to internal surface  70  of bowl-shaped depression  64 . Additionally or alternatively, thermal element  110  may be positioned around upper portion  104  of blending chamber  100 , such as around cavity  42  of lid  20 . Thermal element  110  additionally or alternatively may be positioned proximate to and/or adjacent to blending element  22  to transfer thermal energy to blending element  22 . 
     Regardless of where thermal element  110  is included around blending chamber  100 , thermal element  110  may be positioned proximate bowl-shaped depression  64  to reduce energy losses and/or increase energy transfer between thermal element  110  and blending chamber  100 . In particular, thermal element  110  may be positioned proximate the walls of the blending chamber (e.g., cavity  42 , bottom  66 , and sidewalls  68 ). In other words, thermal element  110  may be positioned adjacent to blending chamber  100 . In particular, thermal element  110  may be positioned in direct, physical contact with the walls (e.g., cavity  42 , bottom  66 , and sidewalls  68 ) of blending chamber  100  and/or may be coupled to the interior surfaces of the walls of blending chamber  100 . As used herein “internal” or “interior” surfaces refer to surfaces that are opposite external or exterior surfaces and face towards the inside of lid  20  and/or base  60 . Thus, internal surface  70  is opposite external surface  69  and faces inwards, towards the interior/inside of base  60 . As such, thermal element  110  may be on an opposite side of bowl-shaped depression  64  (i.e., the interior side) from solid-shell cosmetic ingredient capsule  300 , which as discussed above, may be placed onto external surface  69  of bowl-shaped depression  64 . This configuration may ensure that thermal element  110  is isolated from fluids in blending chamber  100  (e.g., cosmetic liquid  330 ), thereby preventing damage to thermal element  110 . 
     Thermal element  110  may comprise any suitable structure that is configured to heat blending chamber  100 . In particular, the thermal element  110  may comprise one or more materials, such as a metal, a metal alloy, ceramic, glass, and/or a polymer that is/are configured to increase in electrical resistivity and/or temperature when supplied an electric current and/or when subjected to an electric field. Further, the thermal element  110  may be arranged in any suitable configuration, such as one or more of a coiled heating element, a thick film heating element, a printed heating element, an electric circuit, etc. As one example, thermal element  110  may comprise a flex circuit (e.g., an electric circuit mounted and/or printed on a flexible plastic substrate). As another example, thermal element  110  may comprise an electrically resistive wire. By heating blending chamber  100  and/or solid-shell cosmetic ingredient capsule  300 , thermal element  110  may facilitate blending of the solid-shell cosmetic ingredient capsule  300 . In particular, the thermal element  110  may soften and/or liquefy solid-shell cosmetic ingredient capsule  300 , thereby facilitating more even and homogenous blending by blending element  22 . Further, heating solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  may enhance user experience by ensuring that the cosmetic liquid  330  is warm to the touch when presented for extraction. In particular, heating solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330  may reduce the chance that the cosmetic liquid feels cold to a user. Instead, the cosmetic liquid  330  may provide a warmer, more soothing experience for a user as compared to conventional cosmetics that are stored at room temperature. 
     In addition to, and/or instead of being configured to heat blending chamber  100 , thermal element  110  may be configured to cool (i.e., lower a temperature) of blending chamber  100  and/or cosmetic liquid  330 . As one example, thermal element  110  may comprise a cooling jacket that is configured to house a coolant (e.g., water, an oil, and/or a glycol). In such examples, cosmetic blending device  10  may include a coolant system including one or more of a coolant pump, piping to recirculate coolant between the pump and the cooling jacket, a cooling device (e.g., a fan), and/or a refrigerating device (e.g., compressor, evaporator, condenser, etc.). In examples where thermal element  110  is configured to both heat and cool blending chamber  100 , cosmetic blending device  10  additionally may include a heater that is configured to heat the coolant. In some examples, a separate coolant circuit and coolant pump may be included for the heated coolant supply. However, in other examples, the cosmetic blending device  10  may utilize the same pump for circulating both the heated and the cooled coolant. As an example, cosmetic blending device  10  may include a three-way valve that may switch coolant flow between the heated coolant circuit and the cooled coolant circuit. 
     As another example, thermal element  110  may include a thermoelectric cooling device that may be configured to heat and/or cool blending chamber  100 , and/or the contents contained therein (e.g., solid-shell cosmetic ingredient capsule  300 , cosmetic liquid  330 , and/or blending element  22 ), utilizing the Peltier effect. As an example, the thermal element may include two or more semiconductor materials that are configured to generate a temperature gradient across opposite ends of the semiconductor materials when a voltage is applied across the semiconductor materials (thus causing current flow there-through). The thermoelectric cooling device may be configured to both heat and cool blending chamber  100 , in some examples. In particular, current may flow in a first direction to heat blending chamber  100  and/or in a second opposite direction to cool blending chamber  100 . Thus, switching between heating and cooling may be achieved by reversing the direction of current flow through the device. By cooling cosmetic liquid  330 , cosmetic blending device  10  may ensure that the cosmetic liquid is not too hot when presented to a user for extraction. 
     After the heating and/or blending, when presented to a user, cosmetic liquid  330  may be at least 37° C., at least 38° C., at least 39° C., at least 40° C., at least 41° C., at least 42° C., at least 43° C., at least 44° C., at most 62° C., at most 61° C., at most 60° C., at most 59° C., at most 58° C., at most 56° C., at most 54° C., at most 52° C., at most 50° C., at most 49° C., and/or at most 48° C. 
     Blending element  22  may be configured to be selectively rotated and/or driven by (i.e., receive torque output from) drive mechanism  120 . In particular, drive mechanism  120  may include a mechanical linkage  122  that may be configured to transmit torque output by drive mechanism  120  to blending element  22 . That is, mechanical linkage  122  may mechanically couple and/or connect drive mechanism  120  and blending element  22  to transmit torque there-between. Said another way, blending element  22  may be coupled to and/or driven by drive mechanism  120  via mechanical linkage  122 . Accordingly, mechanical linkage  122  may extend between blending element  22  and drive mechanism  120  and may be directly physically coupled to both blending element  22  and drive mechanism  120 . Thus, in examples where drive mechanism  120  is included in base  60  and blending element  22  is included in lid  20 , mechanical linkage  122  may extend from base  60  to lid  20 . 
     As examples, mechanical linkage  122  may include one or more of shafts, connecting rods, gears, and/or belts. As one example, mechanical linkage  122  may include a worm gear  126  and a belt  124  as best illustrated in  FIGS.  5  and  7   . As another example, mechanical linkage includes a planetary gear and a shaft. However, in other examples, additional gears, shafts, belts, and other mechanical coupling structures may be included depending on the orientation and/or position of the drive mechanism in the cosmetic blending device. 
     Blending element  22  additionally and/or alternatively may be configured to be selectively translated up and down within blending chamber  100  (e.g., repositioned along vertical axis  250 ). In particular, cosmetic blending device  10  may include a linear actuator  129  that is configured to selectively vertically translate blending element  22  up and down within blending chamber  100 . As examples, linear actuator  129  may include one or more of an electric, hydraulic, and/or pneumatic linear actuator. In some examples, the linear actuator may be configured to translate only blending element  22 . As one example, the linear actuator may be included within blending element  22 . In such examples, shaft  24  of blending element  22  may be configured to extend and/or retract responsive to a force provided by linear actuator  129 . In particular, shaft  24  may include concentric shafts that are configured to slide relative to one another to extended and retracted positions, and linear actuator  129  may be configured to adjust the concentric shafts to the extended and retracted positions to selectively translate blending element  22  up and down within blending chamber  100 . As another example, linear actuator  129  may be included between mechanical linkage  122  and blending element  22  and may be configured to move the entire blending element up and down. In yet further examples, linear actuator  129  may be included within mechanical linkage  122  and/or between components of mechanical linkage  122 . In yet further examples, linear actuator  129  may be configured to move both drive mechanism  120  and blending element  22 . As one such example, drive mechanism  120  may be mounted on a movable plate, and linear actuator  129  may be configured to translate the movable plate up and down along vertical axis  250 . In such examples, the mechanical connection between drive mechanism  120  and blending element  22  may remain constant, and thus the entire drive assembly (including mechanical linkage  122 , drive mechanism  120 , and blending element  22 ) may translate up and down together as a single unit. 
     As mentioned above, drive mechanism  120  may be included in lid  20  and/or base  60 . Further, drive mechanism may be oriented vertically or horizontally in lid  20  and/or base  60 . In particular, when mounted vertically, drive mechanism  120  may be configured such that an axis of rotation of its torque output is oriented in the vertical direction, substantially parallel to vertical axis  250 . Conversely, when mounted horizontally in cosmetic blending device  10 , drive mechanism  120  may be configured such that the axis of rotation of a torque output of the drive mechanism is oriented in the horizontal direction, substantially orthogonal to vertical axis  250 . However, in other examples, drive mechanism  120  may be mounted in other orientations, such that the rotational axis of the torque output of the drive mechanism is angled with respect to vertical axis  250 . 
     In some examples, cosmetic blending device  10  may be a manual device that is configured to be operated by hand. In such examples, drive mechanism  120  may include a crank handle, a wheel, and/or other manual rotary device that is configured to be rotated by a user&#39;s hand. Thus, in such examples, a user may manually turn and/or crank drive mechanism  120  to rotate blending element  22  and blend solid-shell cosmetic ingredient capsule  300 . 
     However, in other examples, cosmetic blending device  10  may be an electrically powered device, in which at least drive mechanism  120  may be configured to be driven by electrical energy. As an example, drive mechanism  120  may include an electric motor. In such examples, drive mechanism  120  may be configured to be driven by an electric power source  160 . Electric power source  160  may include an external electrical energy source  162  (e.g., a wall socket, a charging station, etc.) that is positioned outside cosmetic blending device  10  and/or an internal electrical energy source  166  (e.g., a battery) that is included within cosmetic blending device  10 . Thus, cosmetic blending device  10  may be configured to be powered by external electrical energy source  162 , and/or may include its own internal electrical energy source, namely, internal electrical energy source  166 . 
     When electric power source  160  includes external electrical energy source  162 , cosmetic blending device  10  may be configured to be selectively electrically connected to external electrical energy source  162  via a wired and/or wireless electrical connection. For example, cosmetic blending device  10  may include a port, a cable, a wire, and/or a cord that is/are configured to electrically connect cosmetic blending device  10  to external electrical energy source  162 . External electrical energy source  162  may include a wall socket, an electrical power plug, an electrical power a socket, an external battery, a charging station, and/or an extension cord. 
     When electric power source  160  includes internal electrical energy source  166 , internal electrical energy source  166  may be configured to store electrical energy. For example, internal electrical energy source  166  may include a battery  167 . Internal electrical energy source  166  may include a single battery and/or a battery cell, although it is within the scope of the present disclosure that internal electrical energy source  166  may include multiple batteries and/or battery cells. Battery  167  may include a rechargeable battery. To charge the rechargeable battery, internal electrical energy source  166  may be configured to be selectively electrically connected (e.g., via a wired and/or wireless connection) to a charging station  164  of external electrical energy source  162 . Thus in some examples, such as when cosmetic blending device  10  includes internal electrical energy source  166 , external electrical energy source  162  may include charging station  164 . Charging station  164  may be configured to supply electrical energy to cosmetic blending device  10  via a wired and/or wireless electrical connection with internal electrical energy source  166 . Charging station  164  may in turn be electrically connected to a wall socket, an electrical power plug, an electrical power socket, and/or an external battery. 
     Internal electrical energy source  166  may be configured to be selectively removed from cosmetic blending device  10 . For example, when internal electrical energy source  166  includes a disposable battery, the disposable battery may be configured to be selectively removed from cosmetic blending device  10  and/or replaced. As another example, when internal electrical energy source  166  includes a rechargeable battery, the rechargeable battery may be configured to be selectively removed and subsequently electrically connected to external electrical energy source  162 . In such examples, the rechargeable battery may be electrically connected to the external electrical energy source  162  via a direct, wired connection. 
     Internal electrical energy source  166  may be included in lid  20  and/or base  60 . When base  60  includes internal electrical energy source  166 , internal electrical energy source  166  may be positioned below enclosed blending chamber  100 . Additionally or alternatively, lid  20  may include internal electrical energy source  166 . When both base  60  and lid  20  include internal electrical energy source  166 , internal electrical energy source  166  may include multiple batteries that are distributed amongst lid  20  and base  60 . 
     Distribution of electrical power from electric power source  160  may be regulated, controlled, and/or adjusted by a control system  170 , also referred to as a regulator,  170 . That is, cosmetic blending device  10  may include control system  170 , and control system  170  may be configured to regulate, control, and/or adjust operation of actuators  118  (e.g., drive mechanism  120  and/or linear actuator  129 ), sensors  195 , and/or other electrically powered components of cosmetic blending device  10  (e.g., thermal element  110 ). In particular, control system  170  may include a controller  172  that may be configured to selectively adjust operation of one or more actuators  118 , sensors  195 , and/or other electrically powered components of cosmetic blending device  10  by one or more of adjusting an amount of electrical power supplied to the actuators, sensors, and/or other electrically powered components of the cosmetic blending device by the electric power source, and/or by adjusting a control signal sent to dedicated (i.e., component-specific) control circuits of the actuators, sensors, and/or other electrically powered components of the cosmetic blending system. 
     Controller  172  may be, may be implemented as, and/or may include at least one controller  172 , at least two controllers  172 , at least three controllers  172 , at least four controllers, at least five controllers  172 , and/or at least six controllers  172 . When more than one controller  172  is included, the individual controllers may be included at various positions and/or configured to regulate, direct, and/or otherwise control specific portions and/or operations of the cosmetic blending device. When a plurality of controllers  172  are utilized, the individual controllers may be referred to as subcontrollers, component-specific controllers, and/or feature controllers. Additionally or alternatively, the plurality of controller as a whole may be collectively referred to as a controller assembly. As one example, controller  172  may include a central controller  174  (e.g., a microcontroller or microprocessor) and one or more dedicated, component-specific controllers that may be configured to regulate an amount of electrical power supplied to their associated actuator, sensor, and/or other electrically powered component. 
     For example, controller  172  may include a motor controller  180  that may be configured to control an amount of electrical power (e.g., voltage, current, pulse width, etc.) supplied from electric power source  160  to drive mechanism  120  when drive mechanism  120  is configured as an electric motor. Motor controller  180 , in turn, may be configured to determine the amount of electrical power to be supplied to the drive mechanism based on control signals received from central controller  174 . Thus, central controller  174  may send command signals to the one or more dedicated, component-specific controllers (e.g., motor controller  180 ) that instruct the component-specific controllers as to how much electrical power to apply to their associated actuator, sensor, and/or other electrically powered component, and the dedicated, component-specific controllers may in turn adjust the amount of electrical power supplied to their associated actuator, sensor, and/or electrically powered component based on the received command signals. Stated another way, central controller  174  may indirectly adjust the amount of electrical power supplied to the actuators, sensors, and/or other electrically powered components of cosmetic blending device  10  by adjusting the command signal sent to the dedicated, component-specific controllers associated with each of these sensors, actuators, and/or other electrically powered components. 
     Central controller  174  additionally and/or alternatively may directly adjust an amount of electrical power supplied to one or more of the sensors, actuators and/or other electrically powered components. As one example, central controller  174  may directly adjust an amount of electrical power supplied to thermal element  110 . As another example, motor controller  180  may be omitted, and central controller  174  may directly adjust an amount of electric power supplied to drive mechanism  120 . 
     At least central controller  174 , and optionally each controller  172 , may include a memory unit  182  and/or a processing unit  188 . Memory unit  182  may be configured to store computer-readable instructions ((e.g., the software) in non-transitory memory, and processing unit  188  may be configured to execute the stored computer-readable instructions responsive to various inputs (e.g., sensor and/or user inputs) to perform various computing functions and/or to selectively control the various electrically powered components of the cosmetic blending device. 
     Memory unit  182  may include non-volatile memory  184 , also referred to herein as non-transitory memory  184 , (e.g., ROM, PROM, and EPROM) and/or volatile memory  186 , also referred to herein as transitory memory  186 , (e.g., RAM, SRAM, and DRAM). Non-volatile memory  184  may be configured to store non-transitory computer-readable instructions. The computer-readable instructions may include instructions for performing one or more methods, such as methods  400  schematically represented in  FIG.  14   . As an example, the computer-readable instructions may comprise instructions for adjusting operation (e.g., an amount of power supplied to) of one or more of drive mechanism  120 , thermal element  110 , and linear actuator  129  based on one or more of user inputs, a characteristic of solid-shell cosmetic ingredient capsule  300 , and/or feedback from one or more sensors. 
     Processing unit  188  may include integrated circuits including one or more of field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, microcontrollers, programmable array logic (PALs), and complex programmable logic devices (CPLDs). 
     Control system  170  may include sensors  195  that may be configured to provide feedback to controller  172 . In particular, the sensors may be configured to measure a blend parameter (e.g., motor torque, electric current, blending element rotational speed, drive mechanism rotational speed, blend temperature, a weight of solid-shell cosmetic ingredient capsule  300 , etc.) and provide feedback to the controller on the current (i.e., real-time) status of the heating and/or blending in the form of electrical signals. In some examples, the sensors may be configured to convert measured blend parameters (e.g., rotational speed, torque, temperature, electric, time, etc.) into electrical signals that may be communicated to controller  172 . For example, the blend parameters may include a temperature of one or more of thermal element  110 , blending chamber  100 , solid-shell cosmetic ingredient capsule  300 , and/or cosmetic liquid  330 , a torque of drive mechanism  120  and/or blending element  22 , a load or strain on drive mechanism  120  and/or blending element  22 , a viscosity of cosmetic liquid  330 , a time during which the drive mechanism and/or the blending element has been activated, and/or a rotational speed of the blending element and/or of drive mechanism  120 . 
     As one example, control system  170  may include a temperature sensor  196  (also referred to as thermal sensor  196 ). Temperature sensor  196  may be configured to measure, estimate, and/or determine a temperature of thermal element  110 , blending chamber  100 , solid-shell cosmetic ingredient capsule  300 , blending element  22 , and/or cosmetic liquid  330 . In particular, temperature sensor  196  may be configured to convert the measured temperature into an electrical signal that may be communicated to controller  172 . Thus, temperature sensor  196  may be configured to output an electrical signal indicative of the temperature of one or more of thermal element  110 , blending chamber  100 , solid-shell cosmetic ingredient capsule  300 , blending element  22 , and/or cosmetic liquid  330 . As examples, the temperature sensor  196  may comprise one or more of a thermocouple, thermistor, resistance thermometer, and/or semiconductor-based temperature sensor. As discussed in more detail herein, controller  172  may be programmed to adjust operation of thermal element  110  based on feedback from temperature sensor  196 . 
     As another example, control system  170  may include a blending element sensor  200 . Blending element sensor  200  may be configured to measure one or more operational characteristics of blending element  22 . In particular, blending element sensor  200  may be configured to measure one or more of a torque generated by drive mechanism  120 , a torque exerted on blending element  22  by drive mechanism  120 , a torque exerted on blending element  22  by solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 , and/or a rotational speed of blending element  22 . As one example, blending element sensor  200  may comprise a torque sensor that may be configured to measure an amount of torque applied to blending element  22 . The torque sensor may be configured to measure static torque and/or dynamic torque. In particular, the torque sensor may be configured to measure one or more of a torque generated by drive mechanism  120 , a torque exerted on blending element  22  by drive mechanism  120 , and/or a torque exerted on blending element  22  by solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 . Thus, the torque sensor may be configured to output an electrical signal indicative of the torque applied to blending element  22  by, for example, drive mechanism  120  (a torque encouraging rotation of blending element  22 ) and/or by solid-shell cosmetic ingredient capsule  300  (i.e., a torque that resists and/or opposes rotation of blending element  22 ). As an example, the torque sensor may comprise one or more strain gauges. 
     Blending element sensor  200  additionally or alternatively may comprise a rotational speed sensor that may be configured to measure a rotational speed of blending element  22  and/or of drive mechanism  120 . As one example, the rotational speed sensor may comprise a Hall effect sensor. However, the rotational speed sensor may comprise any other suitable rotational speed sensor. Thus, the rotational speed sensor may be configured to output an electrical signal indicative of the rotational speed of blending element  22  and/or of drive mechanism  120 . As discussed, controller  172  may be programmed to adjust operation of drive mechanism  120  based on feedback from the blending element sensor  200 . 
     Sensors  195  additionally or alternatively may include an identification sensor  202  that may be configured to identify a characteristic of solid-shell cosmetic ingredient capsule  300 . The characteristic may be an identity characteristic and/or a physical characteristic of the solid-shell cosmetic ingredient capsule. As examples, the identity characteristic of solid-shell cosmetic ingredient capsule  300  may include one or more of a name, type, serial number, or other identifying parameter of the solid-shell cosmetic ingredient capsule. The physical characteristics of solid-shell cosmetic ingredient capsule  300  may include one or more of a weight, volume, hardness, and/or melting point of solid-shell cosmetic ingredient capsule  300 . In some examples, the identity characteristic may identify, correspond to, and/or otherwise indicate one or more of the physical characteristics of solid-shell cosmetic ingredient capsule  300 . For example, the type of the solid-shell cosmetic ingredient capsule may indicate or otherwise correspond to an intended body surface to which the cosmetic liquid is to be applied (e.g., skin, hair, or nails), an intended effect of the solid-shell cosmetic ingredient capsule (e.g., moisturizing, soothing, exfoliating, etc.), dosage, and/or ingredient type. As discussed in more detail herein, controller  172  may be programmed to set initial blend parameters based on feedback from the temperature sensor. 
     Additionally or alternatively, control system  170 , and in particular, controller  172 , may be programmed to calculate, infer, and/or otherwise estimate one or more of the blend parameters based on electrical properties (e.g., current flow, voltage, internal resistance) of one or more of the electrical components of cosmetic blending device  10 . As an example, controller  172  may calculate, infer, and/or otherwise estimate the rotational speed of drive mechanism  120  and/or blending element  22  based on current flow between drive mechanism  120  and electric power source  160 . As one such example, controller  172  may include an electric circuit configured to measure current flow between drive mechanism  120  and electric power source  160 . Based on the measured current flow, controller  172  may infer the rotational speed of drive mechanism  120  based on the back electromotive force (back-EMF) since the back-EMF may be directly proportional to the rotational speed of the drive mechanism. In particular, the rotational speed may be related to the back-EMF based on a known back-EMF constant, K e  (i.e., ω motor =V B-EMF /K e ). The back-EMF may be calculated based on a difference between the measured current flow and an expected current flow (i.e., V B-EMF =R Drive Mechanism ×(I Expected −I Measured ), where the expected current flow may be calculated using Ohm&#39;s law based on the voltage applied to the drive mechanism by controller  172  and/or electric power source  160  and a known internal resistance of the drive mechanism (i.e., I Expected =V Applied /R Drive Mechanism →V B-EMF =V Applied −(R Drive Mechanism ×I Measured )). 
     Each type of solid-shell cosmetic ingredient capsule  300  may include a set of physical characteristics which may or may not be unique, and each capsule&#39;s set of physical characteristics may be tied, linked, associated with, and/or otherwise correlated to a unique identity characteristic. That is, physical characteristics of solid-shell cosmetic ingredient capsule  300  may be categorized based on the identity characteristic of the solid-shell cosmetic ingredient capsule. In this way, the controller may identify the physical characteristics of solid-shell cosmetic ingredient capsule  300  based on the identity characteristic. 
     Controller  172  may be in electrical communication (e.g., via a wired connection and/or wireless connection) with the actuators, sensors, and/or other electrically powered components of the cosmetic blending device to adjust operation thereof and/or receive feedback therefrom, as discussed in greater detail herein. For example, controller  172  may be electrically connected to one or more of drive mechanism  120 , linear actuator  129 , thermal element  110 , temperature sensor  196 , blending element sensor  200  and/or identification sensor  202  via wiring  192 . 
     Thus, electrically powered components of cosmetic blending device  10  may be electrically connected to controller  172  and/or electric power source  160 . Controller  172  may be configured to adjust operation of the actuators (e.g., drive mechanism  120  and/or linear actuator  129 ) based on feedback from the one or more sensors and/or user input. 
     In particular, controller  172  may set and/or determine threshold blend parameters based on user input and/or based on characteristics of solid-shell cosmetic ingredient capsule  300 . Threshold blend parameters may include one or more of a threshold temperature (e.g., threshold temperature of thermal element  110 , threshold temperature of blending chamber  100 , threshold temperature of solid-shell cosmetic ingredient capsule  300 , and/or threshold temperature of cosmetic liquid  330 ), a threshold torque (e.g., a threshold torque output by drive mechanism  120 , a threshold torque exerted on blending element  22  by drive mechanism  120 , and/or a threshold torque exerted on drive mechanism  120  by solid-shell cosmetic ingredient capsule  300  and/or cosmetic liquid  330 ), a threshold rotational speed of drive mechanism  120 , a threshold rotational speed of blending element  22 , a threshold height of blending element  22  (i.e., a distance between blending element  22  and bottom  66  of bowl-shaped depression  64 ), a threshold heating duration, and/or a threshold blending duration. The aforementioned thresholds may be minimums, maximums and/or ranges of values for the associated parameters. For example, the threshold temperature may be a minimum temperature, a maximum temperature and/or a range of temperatures. 
     As one example, the threshold blend parameters may be directly set, or selected, by a user. In particular, cosmetic blending device  10  may include a user input device  210  that may be configured to allow a user to manually and/or explicitly set the threshold blend parameters. For example, a user may input a desired cosmetic liquid temperature, desired blending speed, desired blending temperature, one or more additional ingredients that a user desires to include in blending chamber  100 , and/or a desired blending duration. User input device  210  may include one or more of a button, touch screen, joystick, keyboard, and/or other type of user input device that may be configured to receive user input. 
     Additionally or alternatively, controller  172  may set and/or determine the threshold blend parameters based on one or more characteristics (i.e., physical characteristics and/or identity characteristics) of solid-shell cosmetic ingredient capsule  300 . The characteristics may be input by the user via user input device  210  and/or may be determined by the controller based on output from the various sensors, such as from identification sensor  202 . Thus, the controller  172  may determine the identity characteristics of solid-shell cosmetic ingredient capsule  300  based on user input. Additionally or alternatively, controller  172  may determine the identity characteristics of solid-shell cosmetic ingredient capsule  300  based on feedback from identification sensor  202 . 
     For example, identification sensor  202  may be configured to identify a unique identifier of solid-shell cosmetic ingredient capsule  300 . In particular, the unique identifier may be configured to provide an indication of the identity characteristics of the solid-shell cosmetic ingredient capsule (e.g., name, serial number, type, etc.). As examples, the unique identifier may comprise a QR code, barcode, RFID tag, image, and/or any other identifying letter, number, or indicia that may be recognized and/or read by cosmetic blending device  10 . Thus, in some such examples, identification sensor  202  may include a barcode reader, RFID scanner, and/or other type of reader, scanner, or optical sensor. Based on the identity characteristics of the solid-shell cosmetic ingredient capsule  300  identified via the unique identifier, controller  172  may be programmed to determine one or more physical characteristics of solid-shell cosmetic ingredient capsule  300 , such as its weight, hardness, volume, etc. In particular, controller  172  may include a look-up table or other indexing structure stored in non-transitory memory  184  that may associate each unique identifier and/or identity characteristics with known physical characteristics of the identified solid-shell cosmetic ingredient capsule. 
     Based on the identity characteristics and/or associated physical characteristics of the identified solid-shell cosmetic ingredient capsule  300 , the controller  172  may set the threshold blend parameters. In this way, user input device  210  may be configured to permit a user to input one or more of the characteristics of solid-shell cosmetic ingredient capsule  300 . Additionally or alternatively, the controller may be configured to determine the physical characteristics of the solid-shell cosmetic ingredient capsule based on the identity characteristics of the solid-shell cosmetic ingredient capsule, which may be determined based on feedback from identification sensor  202 . 
     Controller  172  additionally or alternatively may be configured to determine the identity characteristics of solid-shell cosmetic ingredient capsule  300  and/or physical characteristics of solid-shell cosmetic ingredient capsule  300  based on a measured physical characteristic of solid-shell cosmetic ingredient capsule  300 . In such examples, identification sensor  202  may be configured to measure a physical characteristic of solid-shell cosmetic ingredient capsule  300  (such as a weight of the solid-shell cosmetic ingredient capsule). As an example, identification sensor  202  may comprise a weight sensor (e.g., digital scale), and the controller may be programmed to set threshold blend parameters based on an indication of the weight of solid-shell cosmetic ingredient capsule  300  obtained from identification sensor  202 . Controller  172  additionally or alternatively may determine one or more identity characteristics of solid-shell cosmetic ingredient capsule  300  and/or other physical characteristics of the solid-shell cosmetic ingredient capsule based on the measured weight, and may adjust and/or set threshold blending parameters accordingly. 
     Based on one or more of the characteristics of the solid-shell cosmetic ingredient capsule, the controller  172  may set and/or determine the threshold blend parameters (e.g., the threshold temperature for thermal element  110 , blending chamber  100 , and/or solid-shell cosmetic ingredient capsule  300 , the threshold torque for blending element  22 , the threshold rotational speed for drive mechanism  120 , the threshold rotational speed for blending element  22 , and/or the threshold height for blending element  22 ). As one example, the controller  172  may adjust blending element  22  to a lower position (closer to bottom  66  of bowl-shaped depression  64 ) for solid-shell cosmetic ingredient capsules  300  having smaller volumes. As another example, controller  172  may set the desired torque and/or rotational speed to higher values for denser and/or harder solid-shell cosmetic ingredient capsules  300 . As yet another example, controller  172  may set the desired temperature to a higher value for solid-shell cosmetic ingredient capsules  300  having a higher melting temperature. Thus, controller  172  may set the threshold blend parameters based on or more of the volume, hardness and/or strength, composition, and/or melting temperature of the solid-shell cosmetic ingredient capsule. These physical characteristics of the solid-shell cosmetic ingredient capsule may in turn be determined based on the identity characteristic of the solid-shell cosmetic ingredient capsule, as discussed above. 
     Thus, controller  172  may be programmed to set the threshold blend parameters, based on a measured physical characteristic of solid-shell cosmetic ingredient capsule  300  and/or based on the identity characteristic of solid-shell cosmetic ingredient capsule  300 . In particular, controller  172  may determine one or more of the physical characteristics by direct measurement (e.g., via a scale), and/or inferentially based on the one or more identity characteristics (e.g., via identification of the unique identifier). Additionally or alternatively, the threshold blend parameters may be adjusted during a blending cycle. As an example, the threshold rotational speed of drive mechanism  120  and/or blending element  22  may be adjusted during a blending cycle to operate the drive mechanism  120  at different speeds throughout a blending cycle. 
     However, in other examples, one, more than one, or even all of the threshold blend parameters may be pre-set. That is, they may be approximately the same for every solid-shell cosmetic ingredient capsule  300 , and controller  172  may not adjust the threshold blend parameters depending on the characteristics of the solid-shell cosmetic ingredient capsule. 
     Controller  172  additionally or alternatively may programmed to control operation of one or more of the electrically powered components of cosmetic blending device  10  (e.g., thermal element  110 , drive mechanism  120 , and/or linear actuator  129 ) during the heating and/or blending, based on feedback from the one or more the sensors. Thus, control system  170  may actively adjust operation of the various electrically powered actuators in a closed-loop feedback control scheme, such as proportional-integral (PI) control or proportional-integral-derivative (PID) control, to more accurately maintain the actual blending parameters at the corresponding thresholds. 
     For example, controller  172  may adjust operation of thermal element  110  based on feedback from temperature sensor  196 , and in particular, based on a difference between a measured temperature (temperature measured by temperature sensor  196 ) and the threshold temperature. In such examples, controller  172  may increase an amount of heat output by thermal element  110  when the measured temperature is less than the threshold temperature and may decrease an amount of heat output by thermal element  110  when a measured temperature is greater than the threshold temperature. The threshold temperature may be at least 27° C., at least 28° C., at least 29° C., at least 30° C., at least 31° C., at least 32.2° C., at least 33° C., at least 34° C., at least 35° C., at least 36° C., at least 37° C., at least 38° C., at most 62° C., at most 61° C., at most 60° C., at most 59° C., at most 58° C., at most 56° C., at most 54° C., at most 52° C., at most 50° C., at most 49° C., and/or at most 48° C. Additionally or alternatively, temperature sensor  196  and/or controller  172  may include a protection circuit that automatically and/or passively reduces an amount of electrical power (and in some examples, completely cuts off the electrical power) supplied to thermal element  110  when the temperature of thermal element  110  increases above an upper threshold temperature. 
     As another example, controller  172  may adjust operation of drive mechanism  120  based on feedback from blending element sensor  200 , and in particular based on a difference between a measured rotational speed and/or a measured torque of blending element  22  (rotational speed and/or torque measured by blending element sensor  200 ) and the threshold rotational speed and/or the threshold torque. In particular, controller  172  may adjust a torque output by drive mechanism  120  and/or increase a rotational speed of blending element  22  and/or of drive mechanism  120  (e.g., by increasing an amount of power supplied to drive mechanism  120 ), when one or more of: a measured static torque (i.e., a reaction torque) is greater than a threshold static torque, a measured dynamic torque is less than a threshold dynamic torque, and/or a measured, calculated, and/or inferred rotational speed is less than a threshold rotational speed. Conversely, controller  172  may decrease the torque output by drive mechanism  120  and/or decrease the rotational speed of blending element  22  when the measured static torque is less than the threshold static torque, the measured dynamic torque is greater than the threshold dynamic torque, and/or the measured rotational speed is greater than the threshold rotational speed. The threshold static torque and/or the threshold dynamic torque may be at least, at least 0.05 Newton-centimeters (N·cm), at least 0.1 N·cm, at least 0.2 N·cm, at least 0.3 N·cm, at least 0.4 N·cm, at least 0.5 N·cm, at least 0.6 N·cm, at least 0.7 N·cm, at least 0.8 N·cm, at least 0.9 N·cm, at least 1 N·cm, at least 2 N·cm, at least 3 N·cm, at most 50 N·cm, at most 40 N·cm, at most 30 N·cm, at most 20 N·cm, at most 10 N·cm, at most 7.5 N·cm, at most 5 N·cm, at most 4 N·cm, at most 3 N·cm, at most 2 N·cm, and/or at most 1 N·cm. 
     The threshold rotational speed may be a threshold rotational speed of drive mechanism  120  and/or of blending element  22 . The rotational speed of blending element  22  may be inferred from a rotational speed of drive mechanism  120 , and vice versa, based on a gear ratio of mechanical linkage  122 . That is, the gear ratio of mechanical linkage  122  may cause blending element  22  to spin at a different angular rotational speed than drive mechanism  120 , and this difference in angular rotational speed may be calculated based on the known gear ratio of mechanical linkage  122 . As examples, the threshold rotational speed may be at least 300 revolutions per minute (RPM), at least 350 RPM, at least 400 RPM, at least 450 RPM, at least 500 RPM, at most 1500 RPM, at most 1400 RPM, at most 1300 RPM, at most 1250 RPM, at most 1200 RPM, at most 1150 RPM, at most 1100 RPM, at most 1050 RPM, at most 1000 RPM, at most 950 RPM, at most 900 RPM, at most 800 RPM, and/or at most 750 RPM. In some examples, rotational speed may be directly measured by blending element sensor  200 . Blending element sensor  200  may be configured to measure a rotational speed of drive mechanism  120  and/or of blending element  22 . However, as described above, in other examples, the rotational speed of the drive mechanism may be inferred based on a measured current flow between drive mechanism  120  and electric power source  160 . 
     As yet another example, controller  172  may adjust a height of blending element  22  based on feedback from blending element sensor  200 . In particular, when the measured torque and/or measured rotational speed is less than desired, controller  172  may command linear actuator  129  to move blending element  22  up and down to facilitate better blending of solid-shell cosmetic ingredient capsule  300 . Stated another way, the linear actuator  129  may repeatedly reciprocate blending element  22  up and down to facilitate more even blending of solid-shell cosmetic ingredient capsule  300 . In other examples, linear actuator  129  may adjust the height of blending element  22  (the distance between blending element  22  and bottom  66  of bowl-shaped depression  64 ) at the beginning of the blending cycle (e.g., prior to spinning blending element  22  with drive mechanism  120 ) to one or more of ensure that blending element  22  crushes the solid-shell cosmetic ingredient capsule, to ensure that blending element  22  actually makes contact with solid-shell cosmetic ingredient capsule  300 , and/or to encourage more contact between blending element  22  and solid-shell cosmetic ingredient capsule  300 . In some such examples, the controller may command linear actuator  129  to adjust the height of blending element  22  at the beginning of the blending cycle only, and after the adjusting, may maintain the blending element at the same height for the remainder of the blending cycle. 
     Additionally or alternatively, controller  172  may adjust the height of the blending element based on the one or more identity characteristics and/or based on the one or more physical characteristics of the solid-shell cosmetic ingredient capsule. As an example, controller  172  may adjust the height of blending element  22  based on a height and/or volume of the solid-shell cosmetic ingredient capsule. Specifically, the controller may command linear actuator  129  to lower blending element  22  closer to bottom  66  of bowl-shaped depression  64  for smaller and/or shorter solid-shell cosmetic ingredient capsules  300  than for larger and/or taller solid-shell cosmetic ingredient capsules  300 . By adjusting the height of the blending element based on the size, volume, and/or height of the solid-shell cosmetic ingredient capsule, the controller may ensure that blending element  22  crushes the solid-shell cosmetic ingredient capsule when the cosmetic blending device is adjusted to the closed position. Additionally or alternatively, the controller may ensure that the blending element makes contact with, and thereby blends, the solid-shell cosmetic ingredient capsule. In this way, controller  172  and actuator  129  may ensure more even and complete blending of the solid-shell cosmetic ingredient capsule, thereby providing a more homogenous cosmetic liquid  330 . 
     As introduced above, controller  172  may adjust one or more of the blend parameters during a blending cycle. As an example, the rotational speed of drive mechanism  120  may be adjusted during a blending cycle to spin drive mechanism  120  at different speeds during the blending cycle. In such an example, the threshold rotational speed may be set lower and/or to zero (i.e., drive mechanism  120  powered off) during a first portion of a blending cycle, may be gradually ramped up to a maximum threshold rotational speed during a second portion of a blending cycle, and/or may be operated at the maximum rotational speed during a third portion of a blending cycle. In some examples, the first portion of the blending cycle may comprise a time period (e.g., the first 4, 5, 6, 7, 8, 9, 10, etc., seconds of a blending cycle), may be based on one or more sensed parameters (e.g., a measured temperature), and/or may be based on a state of solid-shell cosmetic ingredient capsule  300 . As an example, the drive mechanism  120  may not be powered on until the measured temperature reaches the threshold temperature (e.g., at least the melting temperature of solid-shell cosmetic ingredient capsule  300 ) and/or until solid-shell cosmetic ingredient capsule  300  has at least partially melted and/or otherwise softened. Thus, in some such examples, the solid-shell cosmetic ingredient capsule initially may be heated by thermal element  110  until it is soft and/or at least partially melted before the blending (via blending element  22 ) is initiated. 
     Pre-heating the solid-shell cosmetic ingredient capsule prior to powering on the drive mechanism may enhance the blending and result in a more homogenous cosmetic liquid. This is because softening and/or melting the solid-shell cosmetic ingredient capsule prior to blending may reduce undesirable splattering of the solid-shell cosmetic ingredient capsule. In particular, pieces of the solid-shell cosmetic ingredient capsule may be flung around blending chamber  100  and/or become lodged in blending element  22  (e.g., in-between cutting edges  28 ) when the drive mechanism  120  is powered on before the solid-shell cosmetic ingredient capsule is sufficiently soft and/or melted. 
     Additionally or alternatively, controller  172  may be programmed to pulse and/or otherwise repetitively adjust one or more of the rotational speed and/or rotational direction of drive mechanism  120 . More abrupt changes in rotational speed and/or direction (e.g., by way of pulsing) may mitigate and/or prevent the buildup of chunks of solid-shell cosmetic ingredient capsule  300  in and/or on blending element  22 , and/or may dislodge chunks that have already built up on blending element  22 , thereby facilitating more even and complete blending of solid-shell cosmetic ingredient capsule  300 . 
     As another example, the threshold temperature may be adjusted during a blending cycle. For example, when the threshold temperature during the blending is hotter than a user-friendly temperature (e.g., hotter than 48.9° C., 55° C., and/or 60° C.), the threshold temperature may lowered to the user-friendly temperature (e.g., 38° C., 40° C., 42° C., 44° C., 46° C., 48° C. and/or 49° C.) once solid-shell cosmetic ingredient capsule  300  has been fully converted to cosmetic liquid  330 , thus allowing the cosmetic liquid to cool to the user-friendly temperature before terminating the heat and blending cycle and allowing a user to extract the cosmetic liquid. This may increase user safety and/or reduce user discomfort when applying cosmetic liquid  330 . 
     By including sensors configured to measure the blend parameters and/or by otherwise measuring various operating parameters (e.g., current flow between drive mechanism  120  and electric power source  160 ), and by including a controller that employs closed-loop feedback control, blending device  10  may more accurately control the blending parameters, thereby ensuring more homogenous and even mixing of solid-shell cosmetic ingredient capsule  300 . 
     In some examples, when the electrically connected components of the cosmetic blending device are positioned in discrete parts of the cosmetic device (e.g., where one component is included in lid  20  and another is included in base  60 ), cosmetic blending device  10  may include a power transmitting structure  204  that is configured to transmit electrical power between base  60  and lid  20 . As one example, electric power source  160  may be included in base  60 , and drive mechanism  120  may be included in lid  20 . As another example, controller  172  may be included in base  60 , and drive mechanism  120  may be included in lid  20 . As yet another example, thermal element  110  may be included in lid  20  and controller  172  and/or electric power source  160  may be included in base  60 . In a still further example, thermal element  110  may be included in base  60  and controller  172  and/or electric power source  160  may be included in lid  20 . 
     Regardless of which components are included in lid  20  and base  60 , power transmitting structure  204  may include an interlock  206  that may be configured to transmit power between base  60  and lid  20  when base  60  and lid  20  are in the closed position. In some examples, power transmitting structure  204  may be configured to only permit power to be transmitted between base  60  and lid  20  when base  60  and lid  20  are in the closed position. That is, interlock  206  may prevent power transmitting structure  204  from transmitting electrical power between base  60  and lid  20  when base  60  and lid  20  are not in closed position. Thus, in examples where electric power source  160  is positioned in base  60  and drive mechanism is positioned in lid  20 , power transmitting structure  204  may be configured to permit electrical power to be transmitted from electric power source  160  in base  60  to drive mechanism  120  in lid  20  by providing an electrical connect between base  60  and lid  20 . 
     Interlock  206  may include any suitable electrically conductive structures in base  60  and lid  20  that may be configured to come in contact, or at least operatively close proximity to one another, when base  60  and lid  20  are in the closed position to provide a physical pathway for electric current to flow between base  60  and lid  20 . As one example, interlock  206  may include a pair of mating electrical contacts. In particular, the interlock  206  may include a first electrical contact  207  that may be included in lid  20 , and a second electrical contact  209  that may be included in base  60 . First electrical contact  207  and second electrical contact  209  may physically touch one another and/or be in close enough proximity to another to conduct electric current there-between when lid  20  and base  60  are in the closed position. Interlock  206  may be constructed from an electrically conductive material, such as one or more metals and/or metal alloys. 
     Power transmitting structure  204  additionally or alternatively may be included in and/or coupled to coupling structure  130 . Specifically, in some examples, interlock  206  may be included in releasable locking structure  134 . As one such example, when releasable locking structure  134  includes threads, the interlock may be coupled to, and/or included in the threads. That is, the threads themselves may include and/or may be constructed from an electrically conductive material that may transmit electricity between the lid and the base when the base and lid are in the closed position. 
       FIGS.  2 - 10    illustrate a less schematic example of a cosmetic blending device  10  according to the present disclosure. The example device of  FIGS.  2 - 10    may be referred to herein as example cosmetic blending device  11 . It is within the scope of the present disclosure that example cosmetic blending device  11  additionally or alternatively may include any of the features, structures, components, variants, and the like that are described and/or illustrated in connection with the cosmetic blending devices  10  of  FIG.  1   . Similarly the cosmetic blending devices  10  illustrated and/or described in connection with  FIG.  1    additionally or alternatively may include any of the features, structures, components, variants, and the like that are described and/or illustrated in connection with example cosmetic blending device  11  of  FIGS.  2 - 10   . 
       FIGS.  2 - 4    illustrate the exterior of the example cosmetic blending device  11 , while  FIGS.  5 - 8    illustrate the interior of the example cosmetic blending device with portions of outer housing  12  removed to enable illustration of interior components of the device. In  FIGS.  2 - 4   ,  FIG.  2    illustrates the example cosmetic blending device in the closed position,  FIG.  3    illustrates the example cosmetic blending device in the open position, and  FIG.  4    illustrates the base of the example cosmetic blending device when it includes cosmetic liquid  330 , such as after the completion of a blending cycle.  FIGS.  5 - 8    illustrate different isometric views of the interior of the example cosmetic blending device, with bottom cap  38  of lid  20  and top cap  61  of base  60  removed to more clearly show some of the interior components of the example cosmetic blending device  11 .  FIGS.  9 - 10    illustrate cross-sectional views of example cosmetic blending device  11 . In particular,  FIG.  9    illustrates a cross-section of example cosmetic blending device  11  taken along a longitudinal plane defined by longitudinal axis  254  and vertical axis  250 .  FIG.  10    illustrated a cross-section of example cosmetic blending device  11  taken along a lateral plane defined by lateral axis  252  and vertical axis  250 . Axes  250 ,  252 , and  254  are orthogonal to one another, and thus define three orthogonal planes in three-dimensional space. 
     As described in greater detail herein, a user may adjust the cosmetic blending device to the open position and insert solid-shell cosmetic ingredient capsule  300  (as illustrated in  FIG.  3   ). A user then may adjust the cosmetic blending device to the closed position (as illustrated in  FIG.  2   ) and initiate a blending cycle by, for example, pressing a button  212  or other actuator. Once the blending cycle is complete (i.e., cosmetic blending device  10  has completed the heating and blending of solid-shell cosmetic ingredient capsule  300  to form cosmetic liquid  330 ), the cosmetic blending device may notify the user that the cosmetic liquid is ready for extraction, such as via one or more lights  221  and/or one or more sounds. A user then may adjust the cosmetic blending device to the open position and extract cosmetic liquid  330  (as illustrated somewhat schematically in  FIG.  4   ). 
     When lid  20  and base  60  are in the closed position (as illustrated in  FIG.  2   ), only housing  12 , user input device  210 , and optionally a user feedback device  220  may be visible to a user. Thus, the user input device  210 , user feedback device  220  and housing  12  may define the exterior of example cosmetic blending device  11 . In example cosmetic blending device  11 , user input device  210  and user feedback device  220  are included in base  60 . However, in other examples, user input device  210  and/or user feedback device  220  may be included in lid  20 . The user input device  210  may comprise button  212 , and button  212  may be configured to initiate a blending cycle as introduced above. As an example, button  212  may be an ON/OFF button that may be configured to initiate a blending cycle. In particular, button  212  may be configured to depress when pushed by a user. User input device  210  may include a spring  214  (shown in  FIG.  7   ) or other biasing mechanism or toggle behind button  212 , (on the inside of base  60 , interior to housing  12 ) that may compress to permit button  212  to depress when pushed/pressed by a user. The spring, in turn, may activate one or more circuits on controller  172 , which may cause the controller  172  to initiate the heating and blending. Thus, the example cosmetic blending device  11  may be described as including a spring-actuated, or biased, ON/OFF button. 
     In other examples of cosmetic blending devices  10  according to the present disclosure, the user input device  210  may comprise other types of ON/OFF buttons, and/or may include more than one button. It also is within the scope of the present disclosure that user input device  210  may include other types of user input devices  210 , such as touchscreens, joysticks, switches, etc. Further, as described above in the description of  FIG.  1   , controller  172  may be configured to initiate the heating and blending without input from a user, and instead may initiate the blending cycle autonomously based on sensed parameters. For example, controller  172  may automatically initiate a blending cycle in response to sensing that lid  20  and base  60  are in the closed position when controller  172  has determined that solid-shell cosmetic ingredient capsule  300  has been inserted into bowl-shaped depression  64 . 
     User feedback device  220  may be configured to indicate a status of the heating and blending to the user and/or a fault condition. For example, user feedback device  220  may include one or more lights  221 . Lights  221  may be configured to notify, or alert, a user of such statuses of the device as when the cosmetic blending device is ready to be actuated, when the device is operating to form cosmetic liquid  330  from solid-shell cosmetic ingredient capsule  300 , and/or when the blending cycle is complete and cosmetic liquid  330  is ready for application to the user&#39;s skin, hair, and/or nails. For example, one or more of the brightness/intensity, color, and/or illumination pattern of lights  221  may change to indicate one or more of these statuses, with different lights being actuated and/or different illumination patterns optionally being utilized to differentiate the various statuses. The lights may be generated by a light source  222  (shown in  FIGS.  5   . and  7 ). The light source may include LED and/or halogen bulbs. Although five lights are shown in  FIG.  2   , other numbers of lights may be used, with examples including one light, two to four lights, and more than five lights. Additionally or alternatively, other types of hardware may be included to provide other visual alerts and/or different types of alerts, such as audible and/or tactile alerts. For example, the user feedback device  220  may include a display screen (for providing different visual alerts), and/or a speaker (for providing audible alerts). 
     When lid  20  and base  60  of example cosmetic blending device  11  are adjusted to the open position (as illustrated in  FIG.  3   ), lid  20  and base  60  are separated to reveal and provide access to blending element  22  of lid  20  and bowl-shaped depression  64  of base  60 . In example cosmetic blending device  11 , lid  20  and base  60  are not connected by a hinge or other tether when the device is in the open position, and the lid and base thus may be described as being completely decoupled when the device is in the open position. As discussed herein, it is within the scope of the present disclosure that lid  20  and base  60  optionally may be interconnected by a hinge, tether, or other permanent coupling structure when the device is in the open position. 
     As illustrated in  FIG.  3   , when lid  20  and base  60  are in the open position, solid-shell cosmetic ingredient capsule  300  may be inserted into bowl-shaped depression  64  of base  60 , and optionally into cosmetic ingredient receptacle  150  when the example cosmetic blending device  11  is used with such a receptacle. When included, cosmetic ingredient receptacle  150  may be inserted into bowl-shaped depression  64 . Cosmetic ingredient receptacle  150  may be configured to line bowl-shaped depression  64 . As such, cosmetic ingredient receptacle  150  may have the same and/or similar geometry to bowl-shaped depression  64 , as illustrated in  FIG.  3   . After inserting solid-shell cosmetic ingredient capsule  300  (and optionally cosmetic ingredient receptacle  150 ) into bowl-shaped depression  64  of base  60 , a user then may couple lid  20  to base  60  and adjust lid  20  and base  60  to the closed position (illustrated in  FIG.  2   ). 
     Base  60  may include a top cap  61  that may at least partially surround bowl-shaped depression  64 , and lid  20  may include a bottom cap  38  that may at least partially surround cavity  42 . Top cap  61  and bowl-shaped depression  64  may be integrally formed together during the manufacturing process (e.g., they may be injection molded or die casted together), and thus may form a unitary piece. However, in other examples, top cap  61  and bowl-shaped depression  64  may be manufactured separately and may form two or more discrete pieces. In such examples, bowl-shaped depression  64  and top cap  61  may be coupled to one another after they are produced, such as via an adhesive, weld, and/or fastener. 
     Top cap  61  and bowl-shaped depression  64  may be fluidly sealed with respect to one another to restrict and/or prevent fluid flow there-between. As an example, example cosmetic blending device  11  may include a seal  78  (shown in  FIGS.  7 - 10   ) between top cap  61  (shown in  FIG.  3   ) and bowl-shaped depression  64 . Seal  78  may be configured to ensure that cosmetic liquid  330  and/or any other fluids in bowl-shaped depression do not leak, spill, and/or otherwise pass into the interior of base  60 , such as to liquid-sensitive internal components like controller  172  and/or internal electrical energy source  166 . Seal  78  may extend around a periphery of bowl-shaped depression  64 , underneath the bowl-shaped depression  64 , or between the bowl-shaped depression and the top cap. In particular, bowl-shaped depression  64  may include a chamfered edge  72  at a top of the bowl-shaped depression, most proximate top  62  of base  60 , and seal  78  may be positioned underneath this chamfered edge  72  of the bowl-shaped depression. Bowl-shaped depression  64  further may include an optional spout  74  that may be configured to funnel and/or pour out cosmetic liquid  330 , as illustrated in  FIG.  3   . As discussed herein, a user optionally may choose to dispense, or remove, cosmetic liquid  330  by dipping one or more of the user&#39;s fingers into the cosmetic liquid within bowl-shaped depression  64 . Spout  74  may form a groove in chamfered edge  72  and/or sidewalls  68  of bowl-shaped depression  64 . 
     Bottom cap  38  of lid  20  may form and/or define cavity  42 . Blending element  22  may extend and/or protrude from at least a portion of cavity  42 , such that cutting edges  28  extend into bowl-shaped depression  64  when lid  20  and base  60  are adjusted to the closed position. When adjusted to the closed position (as illustrated in  FIG.  2   ), bottom cap  38  of lid  20  may overlie top cap  61  of base  60 . Stated slightly differently, top cap  61  of base  60  may extend inside cavity  42 . In this way, top cap  61  of base  60  and bottom cap  38  of lid  20  may overlap when lid  20  and base  60  are adjusted to the closed position. 
     As perhaps best seen in  FIG.  3   , top cap  61  and bottom cap  38  may include portions of releasable locking structure  134  in the regions where top cap  61  and bottom  38  overlap and directly interface with one another. For example, the portion of the releasable locking structure  134  included in base  60  may be positioned on a peripheral exterior surface of top cap  61 , and the portion of the releasable locking structure  134  included in lid  20  may be positioned on a peripheral interior surface of bottom cap  38  of lid  20 , as illustrated in at least  FIG.  3   . Thus, when lid  20  is placed on top of base  60 , top cap  61  may extend into cavity  42  of lid  20 , and bottom cap  38  of lid  20  may surround the periphery of top cap  61  of base  60 . That is, top cap  61  and bottom cap  38  may be concentric, with bottom cap  38  surrounding top cap  61 . 
     In the examples of  FIGS.  2 - 10   , the releasable locking structure  134  of example cosmetic blending device  11  is illustrated as including a threaded engagement. In particular, the portion of releasable locking structure  134  included in base  60  may include threads  136 , and the portion of releasable locking structure  134  included in lid  20  may include grooves  138 . Grooves  138  may be sized and/or otherwise configured to receive threads  136 . As illustrated in  FIG.  3   , threads  136  and grooves  138  may be configured to tighten lid  20  against base  60  when lid  20  is rotated by a user in a clockwise direction (when viewed from above). When threads  136  and grooves  138  are oriented to tighten in this clockwise direction, blending element  22  may be configured to rotate in a counter-clockwise direction (when viewed from above), opposite the tightening direction, as described above in the description of  FIG.  1   . 
     Threads  136  may be integrally included in top cap  61  (e.g., formed concurrently with top cap  61  via injection molding, die casting, etc.), or may be formed separately from top cap  61  and then coupled to top cap  61  afterwards. Grooves  138  may be integrally formed in bottom cap  38  or machined or otherwise cut out of bottom cap  38  after bottom cap  38  is formed. 
     As discussed previously, power transmitting structure  204  may be included in releasable locking structure  134 . In example cosmetic blending device  11 , threads  136  may include at least a portion of power transmitting structure  204 . Power transmitting structure  204  may include separate portions in lid  20  and base  60 . Specifically, power transmitting structure  204  may include a first electrical contact  207  that may be included in lid  20  and a second electrical contact  209  that may be included in base  60 . In example cosmetic blending device  11 , threads  136  may include second electrical contact  209 . As discussed previously, first electrical contact  207  and second electrical contact  209  may include an electrically conductive material that is configured to readily conduct and/or transfer electric current between lid  20  and base  60 . Thus, threads  136  may be constructed from, and/or may include, electrically conductive material, such as one or more metals and/or metal alloys. Threads  136  may be in electrical communication with first electrical contact  207  of lid  20 , via conduction due to direct physical contact with first electrical contact  207  and/or via induction due to close proximity to first electrical contact  207 . 
     In some examples, bottom cap  38  may include an aperture  39  that extends through bottom cap  38  of lid  20 , from groove  138  to an exterior peripheral surface of bottom cap  38  that faces housing  12 . First electrical contact  207  may be positioned between the bottom cap  38  and housing  12 , and may extend through aperture  39  in bottom cap  38  and physically contact threads  136  (as illustrated in at least  FIG.  10   ) when threads  136  are threaded into groove  138 , such as in the closed position. In some examples, first electrical contact  207  may physically contact threads  136  only when lid  20  and base  60  are adjusted to the closed position. In this way, threads  136  and first electrical contact  207  may ensure that interlock  206  transmits power between base  60  and lid  20  only when the lid  20  and base  60  are in the closed position. Thus, in the closed position, threads  136  may extend into groove  138  and may physically contact first electrical contact  207 , which may extend through bottom cap  38  and/or into groove  138  via aperture  39 . 
     Turning to more of the internal components of example cosmetic blending device  11  (illustrated collectively in  FIGS.  5 - 10   ), base  60  provides an example of a cosmetic blending device that includes central controller  174 , which may comprise multiple circuit boards, and internal electrical energy source  166 . Thus, central controller  174  and internal electrical energy source  166  may be included within housing  12 , and below bowl-shaped depression  64 . Internal electrical energy source  166  may include one or more batteries  167 . Batteries  167  may be rechargeable batteries, and in such examples, example cosmetic blending device  11  additionally may include a charge coil  168  that may be configured to accept electric power from charging station  164 . In particular, the charge coil may utilize inductive charging (e.g., Qi charging) to wirelessly transfer power from charging station  164  to batteries  167 . Thus, charge coil  168  may be electrically connected (via a wired or wireless connection) to batteries  167 . Additionally or alternatively, charge coil  168  may be electrically connected to central controller  174  via a charge coil connector  169  (illustrated in  FIGS.  7 - 8   ). 
     Central controller  174  of controller  172  may include a first circuit board  176  and a second circuit board  178 . Second circuit board  178  may be configured to control user feedback device  220  and/or to initiate a blending cycle based on user input from button  212 . Thus, second circuit board  178  may be a user interface circuit board that may be configured to interface with the user (receive input from, and/or provide feedback to, the user). As discussed above, second circuit board  178  may receive input from button  212  via spring  214 . Thus, spring  214  may actuate and/or physically contact second circuit board  178 . Spring  214  may alter a switch or other electrical circuitry of second circuit board  178  when button  212  is pushed by a user to cause second circuit board  178  to initiate a blending cycle. Second circuit board  178  additionally or alternatively may include, support, and/or control light source  222  or other user feedback device  220 . Light source  222  may be positioned between second circuit board  178  and housing  12 , and may be configured to project lights  221  through apertures in housing  12 . Second circuit board  178  may be programmed to control light source  222  to adjust one or more of the intensity, color, and/or illumination pattern of the lights to provide feedback to a user, such as to indicate a device status and/or provide an alert to the user, examples of which are discussed herein. 
     First circuit board  176  (as illustrated in at least  FIG.  5   ) may be configured to control some or all of the other autonomous operation of example cosmetic blending device  11  (e.g., determining blend parameters, running the heating and blending during a blending cycle, adjusting blend parameters during a blending cycle, controlling operation of the various electronic actuators, receiving feedback from the various sensors, etc.). Thus, first circuit board  176  may include charge coil connector  169 . 
     Additionally or alternatively, first circuit board  176  may include a thermistor connector  199  that may be configured to electrically connect first circuit board  176  to a thermistor  198  of thermal sensor  196 . Thus, thermal sensor  196  may include thermistor  198 , and thermistor  198  may be configured to measure a temperature of one or more thermal element(s)  110 , blending chamber  100 , capsule  300 , cosmetic liquid  330 , and/or blending element  22 , as described in more detail herein. Thermistor  198  may be coupled to an exterior, peripheral surface of thermal element  110  and/or bowl-shaped depression  64 , as illustrated in at least  FIGS.  7 - 8   . Thermal element  110  may further include a thermal breaker  112  that may be configured to automatically restrict and/or interrupt current flow to thermal element  110  to protect thermal element  110  from damage and/or to prevent overheating of thermal element  110 , blending chamber  100 , solid-shell cosmetic ingredient capsule  300 , cosmetic liquid  330 , blending element  22 , and/or other components of example cosmetic blending device  11 . Thus, thermal breaker  112  may be a circuit breaker. In the example illustrated in  FIGS.  4 - 10   , thermal element  110  may include a flex circuit. 
     Base  60  also may include a bowl mount  80  positioned between bowl-shaped depression  64  and the batteries and central controller  174 . Thus, bowl mount  80  may separate central controller  174  and batteries  167  from bowl-shaped depression  64 . Bowl mount  80  may be configured to provide structural support and/or stability to bowl-shaped depression  64 . Thus, bowl-shaped depression  64  may rest on and/or be physically/mechanically supported by bowl mount  80 . 
     Base  60  further may include a motor connector  190  coupled to, included in, and/or supported by, first circuit board  176 . The motor connector  190  may electrically connect wiring  192  for drive mechanism  120  to first circuit board  176  and/or batteries  167 . Wiring  192  may extend from motor connector  190  through an aperture in base mount  80  to second electrical contacts  209 , which may be included in threads  136 , as described above, and/or may be included in their own dedicated structure(s) (as illustrated in at least  FIG.  4   ) in example cosmetic blending device  10 . In particular, wiring  192  may include positive wires  193  that extend to threads  136 , and negative wires  194  that extend to one of second electrical contacts  209  that may comprise its own dedicated structure (i.e., to an electrical contact that is not included in threads  136 ). Thus, electric current in positive wires  193  may flow between motor connector  190  and the threads  136 , and electric current in negative wires  194  may flow between motor connector  190  and one or more of second electrical contacts  209  that may form, define, and/or include their own physical structure in example cosmetic blending device  11 . 
     Current may flow between lid  20  and base  60  by flowing between the second electrical contact  209  and the first electrical contact  207 , as described above. Positive wires  193  then may connect the one or more of the first electrical contacts in contact with threads  136  to drive mechanism  120 , and negative wiring  194  may connect the different one of the first electrical contacts (the one not in contact with the threads) to drive mechanism  120 . Thus, wiring  192  may be included in both lid  20  and base  60 , and may be interrupted only in the transition between lid  20  and base  60 , where first electrical contact  207  and second electrical contact  209  (e.g., threads  136 ) of the power transmitting structure  204  may be configured to selectively transfer current between the wiring in lid  20  and base  60 . 
     Second electrical contact  209  may include at least one second electrical contact  209 , at least two second electrical contacts  209 , at least three second electrical contacts  209 , and/or at least four second electrical contacts  209 . As an example, base  60  may include three second electrical contacts  209 . Two of the three second electrical contacts may be separated from one another by 180 degrees (and thus may be referred to as the diametrically opposed contacts of the three second electrical contacts) and the other one of the three second electrical contacts is positioned in-between these two electrical contacts (hence it is referred to herein as a middle contact of the three second electrical contacts). As one such example, the middle contact is positioned equidistant between the other two of the three second electrical contacts (i.e., 90 degrees from each of the two of the three second electrical contacts). As another example, base  60  may include two threads  136  that are positioned on opposite sides of top cap  61  (e.g., 180 degrees apart from one another as perhaps best illustrated in  FIG.  10    and also as illustrated in  FIGS.  3 - 8   ), each of which include second electrical contact  209 . A third second electrical contact may be included between the two threads and may include its own structure (i.e., it may not be included in a thread). For example, as illustrated in  FIG.  4   , the middle contact of the three second electrical contacts may include a hemispherical contact that extends through an aperture in top cap  61 . 
     The middle contact (e.g., the hemispherical contact) may be configured to connect to opposite wiring from the other two second electrical contacts of the three second electrical contacts. As an example, the hemispherical contact and the threads may be configured to each connect to opposite wiring. In some such examples, the hemispherical contact may be connected to the negative wiring in the base and may be configured to selectively connect to the negative wiring in the lid (via one of the first electrical contacts in the lid), and the threads may be connected to the positive wiring in the base and may be configured to selectively connect to the positive wiring in the lid (via one or more of the first electrical contacts in the lid). 
     First electrical contact  207  may include at least one first electrical contact  207 , at least two first electrical contacts  207 , at least three first electrical contacts  207 , and/or at least four first electrical contacts  207 . As an example, lid  20  may include three first electrical contacts  207 . In some such examples, two of the three first electrical contacts may be configured to connect at least a portion of the negative wiring in the lid to the middle contact of the second electrical contact (e.g., the hemispherical contact) in the base (and thus connecting to the negative wiring in the base). The other first electrical contact may be configured to connect at least a portion of the positive wiring in the lid to at least one of the threads in the base (and thus connecting to the positive wiring in the base). Similar to the second electrical contacts, two of the three first electrical contacts (e.g., the ones configured to selectively connect to the hemispherical contact) may be positioned 180 degrees apart, and the contact in-between these two of the three first electrical contacts (e.g., a middle contact of the three first electrical contacts) may be positioned the same distance from these two of the three first electrical contacts as the middle contact of the three second electrical contacts is positioned from the two diametrically opposed contacts of the three second electrical contacts. In this way, when the lid and the base are adjusted to the closed position, the middle contact of the three first electrical contacts may physically contact one of the two diametrically opposed contacts of the three second electrical contacts (e.g., may physically contact thread  136 ) and one of the two diametrically opposed contacts of first electrical contacts may physically contact the middle contact (e.g., the hemispherical contact) of the three second electrical contacts. 
     By including three of the first electrical contacts and/or three of the second electrical contacts, the lid and the base may be adjusted to the closed position in two different orientations. Stated slightly differently, the closed position may include two different orientations between the lid and the base, and the closed position may be achieved in both orientations. 
     Drive mechanism  120  may include at least one electric motor  121 . Electric motor  121  may have any suitable power rating, or output, to drive blending element  22  to blend capsule  300  to form cosmetic liquid  330 . For example, electric motor  121  may have a motor constant K M  of at least 0.1 Newton-centimeter per square root watt (N·cm·W −1/2 ), at least 0.2 N·cm·W −1/2 , at least 0.3 N·cm·W −1/2 , at least 0.4 N·cm·W −1/2 , at least 0.45 N·cm·W −1/2 , at least 0.5 N·cm·W −1/2 , at least 0.6 N·cm·W −1/2 , at least 0.7 N·cm·W −1/2 , at least 0.8 N·cm·W −1/2 , at least 0.9 N·cm·W −1/2 , at least 1.0 N·cm·W −1/2 , at most 3 N·cm·W −1/2 , at most 2.5 N·cm·W −1/2 , at most 2 N·cm·W −1/2 , at most 1.75 N·cm·W −1/2 , at most 1.5 N·cm·W −1/2 , at most 1.25 N·cm·W −1/2 , and/or at most 1 N·cm·W −1/2 . Thus, positive wires  193  may be connected to a positive terminal of electric motor  121 , and negative wires  194  may be connected to a negative terminal of electric motor  121 . Electric motor  121  may be configured to convert electric energy supplied by controller  172  and/or batteries  167  into mechanical rotation (torque output). Torque output by electric motor  121  may be transmitted to blending element  22  via mechanical linkage  122 . Mechanical linkage  122  may include a belt  124 , worm gear  126 , and helical gear  128 . Belt  124  may be stretched around an output gear of electric motor  121  and worm gear  126  and may be configured to rotate worm gear  126  when electric motor  121  spins. Worm gear  126 , in turn, may be configured to rotate helical gear  128 , except the axis of rotation of worm gear  126  and helical gear  128  may be orthogonal to one another. That is, worm gear  126  may rotate along a rotational axis that is parallel to lateral axis  252 , and helical gear may rotate along a rotational axis that is parallel to vertical axis  250 . In this way, torque output by electric motor  121  may be converted to a vertical orientation when electric motor  121  is oriented in a horizontal position. 
     Helical gear  128  may be configured to co-rotate with blending element  22  such that blending element  22  spins whenever helical gear spins. As examples, helical gear  128  may be integrally formed with blending element  22  (i.e., they may form a unitary piece) and/or may be coupled to blending element  22  (specifically, shaft  24  of blending element  22 ). For example, helical gear  128  may be bonded to blending element  22  and/or fastened to blending element  22 , such as via a threaded engagement. Thus, helical gear  128  and blending element  22  may be rotationally fixed relative to one another, such that they do not rotate relative to one another. That is, they may rotate together (i.e., at the same rate and direction). Electric motor  121  and mechanical linkage  122  may be physically and/or mechanically supported by a motor mount  48 . Motor mount  48  may be positioned above bottom cap  38  of lid  20 , between bottom cap  38  and electric motor  121  and mechanical linkage  122 . 
     In some examples, a blending element seal  32  (shown in  FIG.  10   ) may be included between helical gear  128  and bottom cap  38  of lid  20  to provide a fluid seal between blending element  22  and lid  20 . Thus, blending element seal  32  may fluidly seal blending chamber  100  from the internal component of lid  20  (elements positioned above bottom cap  38  of lid  20 ). Additionally or alternatively, example cosmetic blending device  11  may include a seal  78  in cavity  42  of bottom cap  38 . Seal  78  may be coupled to bottom cap  38  in the cavity and may help fluidly seal blending chamber  100  from the internal components of lid  20 . 
     As illustrated in  FIGS.  3     9 , and  11 , blending element  22  may include three cutting edges  28 , although a greater or lesser number of cutting edges may be utilized as discussed herein. The cutting edges may be spaced apart from one another and may curve upwards, towards helical gear  128 . In some examples, the cutting edges may include the same geometry, size, shape, angle of curvature, pitch, and/or dimensions. Additionally or alternatively, the cutting edges may be positioned at the same height on shaft  24 . For example, the cutting edges may be flush with bottom  26  of blending element  22  and may angle upwards along shaft  24  at a designated pitch. In another example, the cutting edges may be spaced above the bottom of blending element  22  at a common height. However, in other examples, the cutting edges may be different geometries, sizes, shapes, pitches, and/or dimensions, and/or may be positioned at different heights along shaft  24 . 
     Focusing on  FIG.  11   , three examples of blending elements  22  are shown and generally indicated at  23 . The left-most example of blending element  23  comprises a forked cutting surface, effectively including two cutting edges  28 . The middle example of blending elements  23  is the same as the example blending element shown in  FIGS.  3  and  9 - 10    and includes three cutting edges  28 . The right-most example of blending element  23  does not comprise cutting edges  28  and may comprise one or more blunt projections and a flat bottom. As illustrated in  FIG.  11   , blending elements  22  optionally may include one or more voids  30  that may be configured to reduce a weight of blending element  22 . The one or more voids  30  also may be referred to as hollow regions  30 , apertures  30 , and/or cavities  30 . The voids  30  may reduce the weight of the blending element  22  and may therefore reduce the power consumption of electric motor  121 . In this way, the energy efficiency of example cosmetic blending device  11  may be increased. Voids  30 , when present, also may provide more turbulent and/or efficient blending of capsule  300  to produce cosmetic liquid  330 , such as by permitting portions of capsule  300  and/or cosmetic liquid  330  to flow through the voids during operation of device  11 . 
       FIGS.  12  and  13    schematically illustrate examples of solid-shell cosmetic ingredient capsule  300 , according to the present disclosure. For brevity&#39;s sake, solid-shell cosmetic ingredient capsule  300  (also referred to as packageless cosmetic ingredient capsule  300 , single-use cosmetic ingredient capsule  300 , unblended cosmetic product  300 , to-be-blended cosmetic product  300 , cosmetic liquid precursor  300 , not-skin-ready cosmetic product  300 , and/or blendable non-homogenous cosmetic product  300 ) may be referred to as simply capsule  300  in the discussion of the solid-shell cosmetic ingredient capsule herein.  FIG.  12    schematically illustrates how solid-shell cosmetic ingredient capsule  300  may be shipped and/or sold in packaging  340 , which as discussed herein, is removed from the solid-shell cosmetic ingredient capsule prior to insertion of the solid-shell cosmetic ingredient capsule into cosmetic blending device  10 .  FIG.  13    schematically illustrates more detailed cross-sections of various examples of solid-shell cosmetic ingredient capsules  300  according to the present disclosure. 
     More specifically,  FIG.  12    illustrates solid-shell cosmetic ingredient capsule  300  schematically, with a portion of shell  302  cut away, revealing optional components of the solid-shell cosmetic ingredient capsule  300 , such as personal care ingredient  318 .  FIG.  13    illustrates cross-sections of eight example configurations of solid-shell cosmetic ingredient capsule  300 . The eight example configurations are separated by broken lines and illustrate various example combinations of optional components of the solid-shell cosmetic ingredient capsule  300 . However, it should be appreciated that other combinations of the optional components are possible. Additional optional examples are disclosed in U.S. Patent Application Publication No. 2019/0070078, the disclosure of which is incorporated herein by reference. 
     As illustrated in  FIGS.  12  and  13   , solid-shell cosmetic ingredient capsule  300  includes a shell  302  defining an enclosed inner volume  316 . The enclosed inner volume  316  may be, may form, and/or may define a hollow cavity that may be at least partially, and optionally completely, filled with a cosmetic material  317 . Cosmetic material  317  may include at least one of a personal care ingredient  318  and an active ingredient  320 . Thus, the personal care ingredient and/or the active ingredient may be included in enclosed inner volume  316 . Additionally or alternatively, active ingredient  320  may be included in the shell. 
     Shell  302  may be configured to one or more of form, define, enclose, encapsulate, confine, surround, encase, protect, retain, hold, fluidly seal, and/or otherwise provide a barrier between enclosed inner volume  316  and the exterior of solid-shell cosmetic ingredient capsule  300  (i.e., the outside environment). In particular, shell  302  may be configured to be sufficiently rigid to define enclosed inner volume  316  and/or to maintain the shape, integrity, and/or volume of enclosed inner volume  316  prior to insertion of solid-shell cosmetic ingredient capsule  300  into the blending chamber of cosmetic blending device  10 . In particular, shell  302  may be configured to be a solid (i.e., not a liquid) prior to being heated and blended in cosmetic blending device  10  (e.g., from when manufacturing of solid-shell cosmetic ingredient capsule  300  is complete, to when solid-shell cosmetic ingredient capsule  300  is placed into the blending chamber of cosmetic blending device  10 ). Thus, shell  302  may be configured to be a solid during transportation, sale/purchase, and/or storage of solid-shell cosmetic ingredient capsule  300 , and shell  302  may not melt, leak, and/or otherwise deform prior to being inserted into the blending chamber of cosmetic blending device  10 . As such, solid-shell cosmetic ingredient capsule  300  may be referred to herein as being “shelf stable,” meaning that it may be configured to remain solid and/or not oxidize, such as during transportation and/or prior to use in cosmetic blending device  10  to form cosmetic liquid  330 . 
     When shell  302  is below its melting point (also referred to as its melting temperature), and is therefore a solid (i.e., in a solid phase or state), shell  302  may be configured to only deform when compressive loads of at least 1724 N/m 2 , at least 3447 N/m 2 , at least 5,200 N/m 2 , at least 5400 N/m 2 , at least 9,890 N/m 2 , at least 6,900 N/m 2 , at least 8,600 N/m 2 , at least 10,300 N/m 2 , at least 12,000 N/m 2 , at least 13,700 N/m 2 , at least 15,400 N/m 2 , at least 17,100 N/m 2 , at least 18,800 N/m 2 , at least 19,500 N/m 2 , at least 21,200 N/m 2 , at least 24.00 N/m 2 , at least 27,000 N/m 2 , at least 30,000 N/m 2 , at least 33,000 N/m 2 , at least 36,000 N/m 2 , at least 39,000 N/m 2 , at least 42,000 N/m 2 , at least 45,000 N/m 2 , at least 48,000 N/m 2 , at least 51,000 N/m 2 , at least 54,000 N/m 2 , at least 57,000 N/m 2 , at least 60,000 N/m 2 , at least 63,000 N/m 2 , at least 66,000 N/m 2 , at least 69,000 N/m 2 , at least 72,000 N/m 2 , at most 110,000 N/m 2 , at most 105,000 N/m 2 , at most 100,000 N/m 2 , at most 95,000 N/m 2 , at most 90,000 N/m 2 , at most 85,000 N/m 2 , at most 80,000 N/m 2 , at most 75,000 N/m 2 , at most 70,000 N/m 2 , at most 65,000 N/m 2 , and/or at most 60,000 N/m 2  are applied to shell  302 . Further, shell  302  may have a melting point of at least 27° C., at least 28° C., at least 29° C., at least 30° C., at least 31° C., at least 32° C., at least 32.2° C., at least 33° C., at least 34° C., at least 35° C., at least 36° C., at least 37° C., at least 38° C., at least 39° C., at least 40° C., at most 52° C., at most 50° C., at most 48° C., at most 46° C., at most 44° C., at most 43° C., at most 42° C., at most 41° C., at most 40° C., at most 39° C., and/or at most 38° C. This compressive force at which shell  302  begins to deform may be referred to as the load-bearing capacity of shell  302 . Thus, at compressive forces below the load-bearing capacity of shell  302 , shell  302  may not deform, but at compressive forces above the load-bearing capacity of shell  302 , shell  302  may begin to deform. 
     As described above, shell  302  may deform prior to the heating and blending because blending element  22  may crush the shell when lid  20  and base  60  are adjusted to the closed position, after capsule  300  has been inserted into the blending chamber of the cosmetic blending device. That is, when lid  20  and base  60  are adjusted to the closed position, blending element  22  may apply a compressive force to shell  302  that is greater than the load-bearing capacity of the shell and/or otherwise sufficient to deform the shell (i.e., greater than the compressive load above which shell  302  may be configured to deform). However, shell  302  still may be solid after the lid and the base are adjusted to the closed position, before the heating and blending cycle commences. Shell  302  only may be deformed at this point. Thus, although shell  302  may be crushed, squished, and/or otherwise deformed by blending element  22 , shell  302  may not melt to a liquid until the heating and blending cycle commences. That is, shell  302  may only melt and become a liquid after the heating and blending cycle commences. Shell  302  may have any suitable thickness to provide these properties. As examples, shell  302  may have a thickness of at least 0.5 mm, at least 0.75 mm, at least 1 mm, at least 1.25 mm, at least 1.5 mm, at least 2 mm, at least 2.25 mm, at least 2.5 mm, at least 2.75 mm, at least 3 mm, at least 3.25 mm, at least 3.5 mm, at least 3.75 mm, at least 4 mm, at most 10 mm, at most 9 mm, at most 8 mm, at most 7 mm, at most 6 mm, at most 5.5 mm, at most 5 mm, at most 4.5 mm, and/or at most 4 mm. 
     Shell  302  additionally or alternatively may be configured to restrict and/or prevent fluid transfer between enclosed inner volume  316  and the exterior of the solid-shell cosmetic ingredient capsule, such as when enclosed inner volume  316  includes liquids and/or when the capsule is exposed to humid environments. For example, shell  302  may be configured to be, and/or may be constructed from ingredients such that shell  302  is, one or more of hydrophobic, water-resistant, waterproof, and/or otherwise impervious to water. Shell  302  also or alternatively may be configured to not dissolve when exposed to water. In this way, shell  302  may be configured to retain, hold, and/or keep one or more water-based liquids (e.g., when the personal care ingredient and/or active ingredient is water-based) within enclosed inner volume  316 , and/or to prevent escape, leakage, and/or spilling of the liquids out of solid-shell cosmetic ingredient capsule  300 . Thus, shell  302  may be configured not only to define enclosed inner volume  316 , but also to fluidly seal enclosed inner volume  316  from the outside environment. In this way, when cosmetic material  317  includes liquids, shell  302  may be configured to hold, retain, and/or otherwise keep the liquids within enclosed inner volume  316  and prevent them from leaking and/or spilling to the outside environment. Further, shell  302  may be configured to remain solid when in contact with cosmetic material  317  of enclosed inner volume  316 . In this way, shell  302  may be configured to not dissolve and/or otherwise deform when exposed to cosmetic material  317  of enclosed inner volume  316 . Thus, shell  302  may be configured to maintain its shape and/or the shape of enclosed inner volume  316  even when the cosmetic material of enclosed inner volume  316  includes various liquids and/or other fluids. 
     Shell  302  may be configured to have the opposite polarity as personal care ingredient  318 . For example, shell  302  may be configured to be hydrophobic, lipophilic, and/or nonpolar when personal care ingredient  318  is configured to be hydrophilic, lipophobic, and/or polar. Such an opposite polarity may improve the ability of shell  302  to retain cosmetic material  317 , and/or personal care ingredient  318  or active ingredient  320  thereof, within enclosed inner volume  316 . In particular, shell  302  may include one or more nonpolar molecules that may be hydrophobic and/or may not be water-soluble. As one such example, shell  302  may include one or more lipids  305 , such as one or more of fats  306  (butters and/or oils), waxes  308 , and/or phospholipids. Specifically, the lipids may include one or more fatty acids and/or one or more fatty acids in combination with one or more alcohols (e.g., glycerol) to form fatty acid esters, which may comprise the one or more of the butters, oils, waxes, and/or phospholipids. As an example, three fatty acids may combine with glycerol to form a triglyceride (a type of fat). 
     Shell  302  may include only one type of triglyceride in some examples, or shell  302  may include various combinations/blends of triglycerides in other examples. Additionally or alternatively, shell  302  may include one or more triglycerides in combination with various other lipids, such as other butters, oils, waxes, and/or phospholipids. In the description herein, butters are used to refer to fats that are solid at room temperature (20° C.), and oils are used to refer to fats that are liquid at room temperature. Thus, butters and oils are both fats, but butters have a higher melting point than oils (i.e., they may have a higher concentration of saturated fatty acids and/or a lower concentration of unsaturated fatty acids as compared to oils). Examples of suitable oils may include one or more of avocado oil, grape seed oil, hemp oil, primrose oil, bergamot oil, argan oil, and/or olive oil. Examples of suitable butters include one or more of shea butter, coconut-derived fats that are solid at room temperature (e.g., coconut oil), cocoa butter, kokum butter, palm-derived fats that are solid at room temperature (e.g., palm oil), Illipe butter, Murumuru butter, Babassu butter, and/or mango butter. Fats  306 , and in some examples, the triglycerides, may comprise at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at most 99%, at most 95%, at most 90%, at most 85%, at most 80%, at most 75%, at most 70%, at most 65%, at most 60%, at most 55%, and/or at most 50% by weight of shell  302 . 
     Waxes  308 , when present, may include one or more types of waxes. As examples, the waxes may include plant waxes and/or animal waxes, including one or more of carnauba wax, rice bran wax, beeswax, soy wax, lanolin, jojoba wax, and/or paraffin wax. The waxes may be present in shell  302  in any particulate form, such as in bead form. As an example, waxes  308  may include jojoba wax beads and/or other types of wax beads. When included in shell  302 , waxes  308  may comprise at least 2%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at most 45%, at most 40%, at most 35%, at most 30%, at most 25%, at most 20%, at most 15%, and/or at most 10% by weight of shell  302 . 
     Additionally or alternatively, shell  302  may include other nonpolar molecules, such as resins  310 . The resins, when present, may include one or more terpenes and/or terpenoids. As an example, the resins may include shellac. When included in shell  302 , resins  310  may comprise at least 2.5%, at least 5%, at least 7.5%, at least 10%, at least 12.5%, at least 15%, at least 17.5%, at least 20%, at least 25%, at most 40%, at most 35%, at most 30%, at most 25%, at most 20%, at most 17.5%, at most 15%, at most 12.5%, and/or at most 10% by weight of shell  302 . 
     Shell  302  additionally or alternatively may include one or more crystal promoters  312  that may be configured to promote and/or stabilize crystallization in shell  302  (i.e., the formation of crystals in shell  302 ). Thus, the crystal promoters may be configured to form and/or stabilize crystalline and/or lattice structures in shell  302 . As examples, the crystal promoters may include one or more of saturated fats, hydrogenated oils, stearin, interestified fats (and in particular interestified triglycerides), fatty acids, fatty alcohols, fatty acid esters, and/or emulsifiers. When included in shell  302 , crystal promoters  312  may comprise at least 0.25%, at least 0.5%, at least 1.0%, at least 1.5%, at least 2%, at least 2.5%, at least 3%, at least 4%, at least 6%, at least 8%, at least 10%, at least 12%, at least 14%, at most 25%, at most 24%, at most 22%, at most 20%, at most 18%, at most 16%, at most 14%, at most 12% and/or at most 10% by weight of shell  302 . 
     Shell  302  additionally or alternatively may include one or more chemically inert materials  314  that may be configured to not chemically react with other components of shell  302 , such as the fats, waxes, preservatives, and/or resins, when included. As examples, the chemically inert materials may include one or more of silica, alginate, starches, sugars, minerals, and/or gelatin. When included, chemically inert materials  314  may comprise at least 2%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at most 60%, at most 55%, at most 50%, at most 45%, at most 40%, at most 35%, at most 30%, at most 25%, at most 20%, at most 15%, and/or at most 10% by weight of shell  302 . Including the chemically inert materials in the shell may reduce the amount of lipids  305  included in the shell. That is, the chemically inert materials may dilute the lipids in shell  302 . In this way, the chemically inert materials may be included to alter one or more of the strength, rigidity, and/or melting point of capsule  300 . In particular, the amount of chemically inert materials in shell  302  may be increased to increase the strength, rigidity, and/or melting point of capsule  300 . Additionally or alternatively, inclusion of chemically inert materials in the shell  302  may alter the physical properties of the cosmetic liquid. For example, the amount of chemically inert materials in shell  302  may be adjusted to alter one or more characteristics such as texture, color, sheen, skin feel and/or viscosity of cosmetic liquid  330 . 
     Shell  302  additionally or alternatively may include active ingredient  320 . Active ingredient  320  may be configured to provide, and at least contribute to, the desired and/or purported effect of capsule  300  and/or cosmetic liquid  330 . In particular, capsule  300  may be advertised and/or otherwise described to provide one or more purported skin, hair, and/or nail benefits for a user or consumer. As an example, a label may be included with solid-shell cosmetic ingredient capsule  300  that describes the desired effect(s) of the solid-shell cosmetic ingredient capsule  300 . The desired and/or purported effects may include treatment for the underlying causes of one or more skin, hair and/or nail issues/conditions (dryness, wrinkles, acne, pigmentation issues, rosacea, psoriasis, eczema, keratosis pilaris, seborrheic dermatitis etc.), treatment for the symptoms of the one or more skin, hair, and/or nail issues/conditions, anti-aging benefits, anti-wrinkle benefits, lightening, darkening, strengthening, protection, nourishment, and/or other changes to the physical and/or chemical structure of the skin, hair, and/or nails. 
     Additionally or alternatively, active ingredient  320  may be configured to be one or more of pain relieving, antibacterial, anti-inflammatory, antispasmodic, disinfecting, astringent, hypoallergenic, regenerating, hydrating, moisturizing, conditioning, and/or relaxing. As examples, active ingredient  320  may include one or more of alpha-hydroxy acids (e.g., glycolic, lactic, tartaric, and citric acids), polyhydroxy acids, beta-hydroxy acids (e.g., salicylic acid), botanical derivatives (e.g. kojic acid), vitamins (e.g., retinoids, Vitamin A, Vitamin C, Vitamin E, etc.), minerals, silicas, acrylate, essential oils, prescription ingredients, proteins, peptides (e.g., copper peptide), anti-aging agents (e.g., hyaluronic acid, allantoin), antioxidants (e.g., alpha-lipoic acid), anti-wrinkle agents (e.g., dimethylaminoethanol or DMAE), sunscreen agents (e.g. titanium dioxide, zinc oxide), hair repair agents, humectants (e.g., propylene glycol, glycerin), rejuvenating and soothing agents, skin lightening agents (e.g., hydroquinone), skin darkening agents, astringents, disinfectants, and/or liposomes. 
     In some examples, active ingredient  320  may be included by itself in shell  302  without an encapsulating coating  321 . However, in other examples, active ingredient  320  may be included in shell  302  with an encapsulating coating  321 . Examples of encapsulating coating  321  include one or more of a gelatin, wax, fats, lipids, phospholipids, triglycerides, and/or cellulose coating. When coated with encapsulating coating  321 , active ingredient  320  may be discrete and/or non-homogenous with the rest of shell  302 . However, when encapsulating coating  321  is not included, active ingredient  320  may form a homogenous or non-homogenous mixture with the rest of shell  302 . Encapsulating coating  321  also may be referred to as active ingredient coating  321  and/or protective coating  321 . When coated with active ingredient coating  321 , active ingredient  320  may be referred to as a microcapsule  322 . Thus, the microcapsule may include the active ingredient and the active ingredient coating. The protective coating may be configured to prevent dissolution of the microcapsule and/or active ingredient within the solid-shell cosmetic ingredient capsule. Additionally or alternatively, the protective coating may be configured to only dissolve when the solid-shell cosmetic ingredient capsule is heated and blended by cosmetic blending device  10  to produce the cosmetic liquid. Thus, the protective coating may have a melting point of at least the melting point of shell  302  and/or the components of shell  302 . 
     However, because the shell  302  is designed to remain solid prior to insertion into cosmetic blending device  10 , when active ingredient  320  is included in shell  302  without protective coating  321 , the active ingredient nonetheless may not dissolve within shell  302 . Additionally or alternatively, the active ingredient may not oxidize in shell  302  at least in part because of the chemical composition of the shell. In particular, shell  302  may be substantially anhydrous (i.e., at most 4%, at most 2% and/or at most 1% by weight water) and/or completely anhydrous (i.e., may not contain any water) and/or may not contain any gaseous oxygen, and may therefore not oxidize active ingredient  320  when the active ingredient is included in the shell. Thus, by including the active ingredient in the shell, not only may the concentration of the active ingredient in the solid-shell cosmetic ingredient capsule be increased, but also the efficacy of the active ingredient may be increased because the shell may significantly reduce and/or prevent oxidation of the active ingredient compared to the amount that the active ingredient may oxidize in the enclosed inner volume. That is, the active ingredient may oxidize less in the shell than in the enclosed inner volume, particularly in examples where the enclosed inner volume includes air and/or water. 
     Further, by including the active ingredient in the shell, protective coating  321  may be omitted, therefore reducing the cost and complexity of solid-shell cosmetic ingredient capsule  300 . And, as mentioned above, by including the active ingredient in the shell in addition to, and/or instead of, in the enclosed inner volume, the amount (e.g., concentration) of active ingredient in the solid-shell cosmetic ingredient capsule may be increased relative to the amount that may be included when the active ingredient is included only in the enclosed inner volume. In particular, active ingredient  320  may begin to precipitate (i.e., out of the personal care ingredient and/or cosmetic material) at lower concentrations than it will tend to precipitate out of the shell. Thus, by including the active ingredient in the shell, the active ingredient may be included at higher concentrations in the shell than in the enclosed inner volume, without precipitating, thereby increasing the effective dosage of the active ingredient. 
     In examples where active ingredient  320  is included in shell  302 , active ingredient  320  may comprise at least 0.05%, at least 0.1%, at least 0.2%, at least 0.3%, at least 0.4%, at least 0.5%, at least 0.6%, at least 0.7%, at least 0.8%, at least 0.9%, at least 1%, at least 1.1%, at least 1.2%, at least 1.3%, at least 1.4%, at least 1.5%, at least 1.7%, at least 2%, at least 2.25%, at least 2.5%, at least 2.75%, at least 3%, at most 10%, at most 9%, at most 8%, at most 7%, at most 6%, at most 5%, at most 4.5%, at most 4.25%, at most 4%, at most 3.75%, at most 3.5%, at most 3.25%, at most 3%, at most 2.75%, at most 2.5%, at most 2.25%, at most 2%, at most 1.75%, at most 1.5%, at most 1.25% and/or at most 1% by weight of shell  302 . 
     When included in shell  302 , active ingredient  320  may be embedded in the shell. As an example, active ingredient  320  may be fully embedded in shell  302 , such that the shell  302  fully surrounds the active ingredient  320 . Additionally or alternatively, the active ingredient may be partially embedded in shell  302 , such that at least a portion of the active ingredient  320  and/or its encapsulating coating  321  (when included) protrude into and/or, are directly exposed to, enclosed inner volume  316 , as illustrated in  FIG.  13   . 
     Additionally or alternatively, a shell coating  324  may be applied to shell  302  as illustrated in  FIG.  13   . In particular, shell coating  324  may be applied to an interior surface  303  and/or an exterior surface  304  of shell  302 . The shell coating may be configured to provide one or more of added structural integrity to shell  302 , added resistance to oxidation of the shell, and/or added resistance to water penetration into the shell, and/or a barrier between the interior surface of the shell and the contents of the shell&#39;s enclosed internal volume prior to blending of the capsule in the cosmetic blending device. Shell coating  324  additionally or alternatively may be configured to increase the melting point of the shell. As examples, coating  324  may include a gum (e.g., xanthan gum), starch, resin, proteins (e.g. gelatin, zein) and/or cellulose. 
     The exterior surface  304  of shell  302  may interface directly with the external environment (e.g., packaging  340 , ambient air, bowl-shaped depression  64  of cosmetic blending device  10 , etc.). In some examples, shell  302 , and in particular exterior surface  304  of shell  302 , may directly interface with ambient air. In particular, when being placed into cosmetic blending device  10  by a user, solid-shell cosmetic ingredient capsule  300  may not be covered by anything (e.g., packaging, lining, wrappings, etc.) and may interface directly with only ambient air and/or a user&#39;s fingers. Correspondingly, when placed in cosmetic blending device  10 , the exterior surface  304  of shell  302  may directly interface with only ambient air and/or cosmetic blending device  10  (e.g., bowl-shaped depression  64  and/or cosmetic ingredient receptacle  150 ). Thus, when heated and blended by cosmetic blending device  10 , the solid-shell cosmetic ingredient capsule  300  may be devoid of all packaging, wrappings, and/or linings, hence the reference herein to the capsule as packageless cosmetic ingredient capsule  300 . 
     As introduced above, enclosed inner volume  316  may be formed, enclosed, and/or otherwise defined by shell  302 . Thus, enclosed inner volume  316  may define and/or form a hollow enclosed volume, space, and/or cavity that may be configured to be fluidly sealed from the exterior environment. Enclosed inner volume  316  may be configured to comprise, contain, include, and/or otherwise be filled with cosmetic material  317 , such as personal care ingredient  318  and/or active ingredient  320 . Thus, cosmetic material  317  may at least partially, and optionally fully, fill enclosed inner volume  316 . As examples, cosmetic material  317  may fill at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 97%, at least 98%, at least 99%, 100%, at most 100%, at most 99%, at most 95%, at most 90%, at most 85%, at most 80%, at most 75%, and/or at most 70% of the total volume of enclosed inner volume  316 . 
     Since active ingredient  320  already has been discussed (in the context of shell  302 ), for the sake of brevity, the composition of active ingredient  320  is not discussed again herein. When active ingredient  320  is included in cosmetic material  317  and in shell  302 , the active ingredient(s) in cosmetic material  317  may be the same as or different from the active ingredient(s) in shell  302 . By including different actives in shell  302  and cosmetic material  317 , solid-shell cosmetic ingredient capsule  300  may contain two different actives that may otherwise be incompatible with one another. That is, by segregating the two different actives in separate and discrete portions of the solid-shell cosmetic ingredient capsule, the two different actives may not interact prior to the heating and/or blending. In this way, chemically incompatible actives may still be contained in the same solid-shell cosmetic ingredient capsule. 
     Like in shell  302 , active ingredient  320  optionally may include encapsulating coating  321 . When active ingredient  320  is included, encapsulating coating  321  may be configured to prevent dissolution of the active ingredient within the enclosed inner volume  316 , and more specifically to prevent dissolution of the active ingredient in personal care ingredient  318 , when personal care ingredient  318  is included in enclosed inner volume  316 . The encapsulating coating may be configured to provide a fluid seal/barrier between the personal care ingredient and the active ingredient. In this way, the active ingredient may be suspended in and/or fluidly sealed off from personal care ingredient  318  when included in enclosed inner volume  316 . Encapsulating coating  321  thus may prevent and/or restrict oxidation of active ingredient  320 , thereby increasing the efficacy of the active ingredient when solid-shell cosmetic ingredient capsule  300  is applied to a user&#39;s body. However, in other examples, active ingredient  320  may not include the protective coating when it is included in the enclosed inner volume  316 . 
     In other examples, such as illustrated in  FIG.  13   , active ingredient  320  may be included in an optional compartment, or subcapsule,  326 . That is, solid-shell cosmetic ingredient capsule  300  may include a compartment  326  that may include the active ingredient. The compartment  326  may be larger than coating  321  and may be configured to hold, contain, and/or include a larger amount (e.g., weight) of the active ingredient. The compartment  326  may comprise similar materials to active ingredient coating  321 , and/or may include other materials that are configured to be waterproof, water-resistant, nonpolar, hydrophobic, and/or otherwise impervious to water. Thus, the compartment  326 , protective coating  321 , shell coating  324 , and/or shell  302  may be configured to be the opposite polarity of personal care ingredient  318  (e.g., hydrophilic vs. hydrophobic, nonpolar vs. polar) so that they do not dissolve and/or otherwise break down when exposed to personal care ingredient  318 . 
     When included in enclosed inner volume  316 , active ingredient  320  may comprise at least 0.05%, at least 0.1%, at least 0.2%, at least 0.3%, at least 0.4%, at least 0.5%, at least 0.6%, at least 0.7%, at least 0.8%, at least 0.9%, at least 1%, at least 1.1%, at least 1.2%, at least 1.3%, at least 1.4%, at least 1.5%, at least 1.7%, at least 2%, at least 2.25%, at least 2.5%, at least 2.75%, at least 3%, at most 5%, at most 4.5%, at most 4.25%, at most 4%, at most 3.75%, at most 3.5%, at most 3.25%, at most 3%, at most 2.75%, at most 2.5%, at most 2.25%, at most 2%, at most 1.75%, at most 1.5%, at most 1.25%, and/or at most 1% by weight of cosmetic material  317 . 
     Personal care ingredient  318 , when present, may be configured to serve as a base for cosmetic liquid  330  and/or a carrier for active ingredient  320 . Thus, personal care ingredient  318  may be configured to be compatible for application to one or more of a user&#39;s skin, nails, hair, and/or other external body surfaces, but may not actively treat one or more skin, hair, and/or nail issues like, or may not treat to the same degree as, active ingredient  320 . As examples, the personal care ingredient  318  may include a water or oil base and/or may include one or more thickening agents, emollients, emulsifiers, surfactants, and/or other elements that may modify the texture and/or viscosity of cosmetic liquid  330 . Because the personal care ingredient  318  may include water and/or oil, personal care ingredient  318  may be configured to one or more of moisten, or moisturize, a user&#39;s skin, hair, nails, and/or other external body surfaces. As examples, the personal care ingredient may include one or more of a cream, water, oil, gel, serum, mousse, sunscreen, shampoo, conditioner, facemask, lipstick, blemish balm, pigment, emollient (stearyl alcohol), thickening agents (cetyl alcohol, xanthan gum) chemically inert substance (e.g., silica, silicone, dry water, etc.), surfactant, emulsifier, gelatin, and/or cellulose. 
     Personal care ingredient  318  may be in one or more phases, such as solid, liquid, and/or gas. When in liquid form, personal care ingredient  318  may be water-based and/or may include water. Additionally or alternatively, personal care ingredient  318  may include water, but at least some and/or all of the water may be fully encapsulated in a coating, such as a silica-based coating (e.g., dry water). In other examples, personal care ingredient  318  may be oil-based and may be lipophilic and/or may include lipids. Further, when personal care ingredient  318  comprises a liquid, it may include suspended solids, such as the microcapsule. Thus, the microcapsule and/or other solids may be suspended in the personal care ingredient, such as when personal care ingredient  318  is in liquid form. However, in other examples, personal care ingredient  318  may not include any water and/or may be completely anhydrous (i.e., 0% by weight water) and/or substantially anhydrous (i.e., at most 4%, at most 2%, and/or at most 1% by weight water). When personal care ingredient  318  and/or active ingredient  320  include liquid water, the cosmetic material may include a preservative. However, when the cosmetic material is substantially anhydrous and/or otherwise does not include liquid water, cosmetic material  317  and/or the entire solid-shell cosmetic ingredient capsule  300  may be free of preservatives. Additionally or alternatively, personal care ingredient  318  may include a solid phase. As an example, personal care ingredient  318  may include a dry powder. 
     When included in enclosed inner volume  316 , personal care ingredient  318  may comprise at least 50%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at most 100%, at most 99%, at most 98%, at most 97%, at most 96%, at most 95%, at most 90%, at most 80%, at most 70%, and/or at most 60% by weight of cosmetic material  317 . 
     As discussed above in the description of  FIG.  1   , solid-shell cosmetic ingredient capsule  300  may be sized and/or otherwise configured to fit and/or be received in cosmetic blending device  10 , and more specifically, in bowl-shaped depression  64  of the base of cosmetic blending device  10 . As examples, the solid-shell cosmetic ingredient capsule may have a total volume of at least 0.5 ml, at least 0.75 ml, at least 1.0 ml, at least 1.25 ml, at least 1.5 ml, at least 1.75 ml, at least 2 ml, at least 2.25 ml, at least 2.5 ml, at least 2.75 ml, at least 3 ml, at least 3.25 ml, at least 3.5 ml, at least 4 ml, at least 4.5 ml, at least 5 ml, at least 6 ml, at least 7 ml, at least 8 ml, at least 9 ml, at least 10 ml, at most 20 ml, at most 18 ml, at most 16 ml, at most 14 ml, at most 13 ml, at most 12 ml, at most 11 ml, at most 10 ml, at most 9 ml, at most 8 ml, at most 7 ml, at most 6 ml, at most 5 ml, at most 4 ml, and/or at most 3 ml. Enclosed inner volume  316  may comprise a volume of at least 0.4 ml, at least 0.5 ml, at least 0.6 ml, at least 0.7 ml, at least 0.8 ml, at least 0.9 ml, at least 1.0 ml, at least 1.25 ml, at least 1.5 ml, at least 1.75 ml, at least 2 ml, at least 2.25 ml, at least 2.5 ml, at least 2.75 ml, at least 3 ml, at least 3.25 ml, at least 3.5 ml, at least 3.75 ml, at least 4 ml, at least 4.5 ml, at least 5 ml, at most 10 ml, at most 9 ml, at most 8 ml, at most 7 ml, at most 6 ml, at most 5 ml, at most 4 ml, at most 3 ml, at most 2.5 ml, at most 2 ml, and/or at most 1.5 ml. 
     Shell  302  may comprise at least 40%, at least 42%, at least 44%, at least 45%, at least 46%, at least 47%, at least 48%, at least 49%, at least 50%, at most 60%, at most 58%, at most 56%, at most 55%, at most 54%, at most 53%, at most 52%, at most 51%, and/or at most 50% by weight of solid-shell cosmetic ingredient capsule  300 . Cosmetic material  317  may comprise the remaining weight of the solid-shell cosmetic ingredient capsule. For example, the cosmetic material  317  may comprise at least 40%, at least 42%, at least 44%, at least 45%, at least 46%, at least 47%, at least 48%, at least 49%, at least 50%, at most 60%, at most 58%, at most 56%, at most 55%, at most 54%, at most 53%, at most 52%, at most 51%, and/or at most 50% by weight of solid-shell cosmetic ingredient capsule  300 . It should be appreciated that the percentage weight of the various components of the solid-shell cosmetic ingredient capsule relative to the entire weight of the solid-shell cosmetic ingredient capsule may be calculated based on their percentage weight in the shell and/or cosmetic material  317 , since the total weight of the solid-shell cosmetic ingredient capsules may be equal to the sum of the weights of the cosmetic material and the shell. For example, when enclosed inner volume  316  only includes personal care ingredient  318  (i.e., where personal care ingredient  318  comprises 100% by weight of the cosmetic material  317  and/or the cosmetic material does not include active ingredient  320 ), the weight ratio of the shell to the personal care ingredient may be at least 2:3 and at most 3:2. In other embodiments, the weight ratio of the shell to the personal care ingredient may be 1:1, at least 0.8:1, at least 1.2:1, at least 1:2, at least 1:3, at most 3:1, and/or at most 2:1. 
     As illustrated in  FIG.  13   , solid-shell cosmetic ingredient capsule  300  may include various combinations of the above described components. As illustrated in the eight examples of  FIG.  13   , shell  302  may include one or more of active ingredients  320 , with and/or without active ingredient coating  321 , lipids  305  (including one or more of fats  306  and waxes  308 ), resins  310 , crystal promoters  312 , chemically inert materials  314 , and/or shell coating  324 . Additionally or alternatively, enclosed inner volume  316  may include one or more of personal care ingredient  318 , active ingredient  320  (with and/or without active ingredient coating  321 ), and/or compartment  326 . Although eight different examples are illustrated showing various combinations of the above components, other combinations of the above components also are within the scope of the present disclosure, as discussed herein. 
     Solid-shell cosmetic ingredient capsule  300  may be configured to include an identity characteristic and/or the unique identifier that may identify the identity characteristic. As discussed above, the unique identifier may include a QR code, barcode, RFID tag, image, and/or any other identifying letter, number, image or indicia that may be recognized and/or read by cosmetic blending device  10 . Thus, cosmetic ingredient capsule  300  may include one or more of a QR code, RFID tag, barcode, and/or other identifying letter, number, image or other indicia. When included, the barcode, QR code, letter, number, image, and/or other indicia may be printed on the exterior of shell  302 . The RFID tag, when included, may be embedded in shell  302  and/or coupled to the exterior surface of shell  302 . As described above, the entirety of the solid-shell cosmetic ingredient capsule may be heated and/or blended to produce cosmetic liquid  330 . Thus, in such examples, the unique identifier may be heated and/or blended and may become part of cosmetic liquid  330 . 
     Solid-shell cosmetic ingredient capsule  300  may include one or more of decorations, designs, etchings, and/or other ornamentations that may be configured to increase the aesthetics of the solid-shell cosmetic ingredient capsule. 
     As described above, the contents of enclosed inner volume  316  may be confined, retained, secured, kept, and/or otherwise held within enclosed inner volume  316  by shell  302 . However, when placed into cosmetic blending device  10  and heated and/or blended by cosmetic blending device  10 , solid-shell cosmetic ingredient capsule  300  may be configured to transform (e.g., melt and/or mix) to cosmetic liquid  330 . In particular, when heated to above its melting point and/or blended by cosmetic blending device  10 , shell  302  may melt to a liquid and may mix with the contents of enclosed inner volume  316 . In some examples, solid-shell cosmetic ingredient capsule  300  may require the heat and blending forces provided by cosmetic blending device  10  in order to transform to cosmetic liquid  330 . For example, solid-shell cosmetic ingredient capsule  300  may not melt and/or blend when rubbed, squeezed, or otherwise manipulated by a user&#39;s hand. That is, friction and/or compressive forces applied by a user&#39;s hands alone may not be sufficient to form cosmetic liquid  330 . 
     As discussed above in the description of  FIG.  1   , because the solid-shell cosmetic ingredient capsule  300  may not include any packaging, wrapping, and/or lining when it is placed into cosmetic blending device  10 , the entirety of the solid-shell cosmetic ingredient capsule  300 , including the shell  302  and at least one of the personal care ingredient  318  and the active ingredient  320 , may form cosmetic liquid  330 . Cosmetic liquid  330  thus will be in a liquid phase when produced by the cosmetic blending device. In some examples, cosmetic liquid  330  may be warm to a user&#39;s touch (e.g., warmer than a user&#39;s 37° C. body temperature) and/or frothy, as discussed herein. 
     However, even in a liquid phase, cosmetic liquid  330  optionally may be designed to still contain suspended solids. For example, when shell  302  comprises wax beads (e.g., jojoba wax beads), the wax beads may remain in a solid phase, even after heating and blending in cosmetic blending device  10 . Thus, cosmetic blending device  10  may not be configured to melt all of solid-shell cosmetic ingredient capsule  300 . That is, some components of solid-shell cosmetic ingredient capsule  300  may be selected to have melting temperatures that are higher than the maximum blending temperature of cosmetic blending device  10 . Such suspended solids may provide a desired texture and/or feeling to a user, and/or may encourage exfoliation. 
       FIGS.  14  and  15    illustrate examples of methods according to the present disclosure. In particular,  FIG.  14    illustrates examples of methods  400  that may be performed by a user to operate and/or use cosmetic blending device  10  to prepare and/or apply cosmetic liquid  330  from at least one solid-shell cosmetic ingredient capsule  300 .  FIG.  15    illustrates examples of methods  450  that may be performed to form and/or manufacture solid-shell cosmetic ingredient capsule  300 . 
     To operate a cosmetic blending device (e.g., cosmetic blending device  10 ) a user optionally may open a blending chamber (e.g., blending chamber  100 ) of the device at  402 . In particular, a user may adjust a lid (e.g., lid  20 ) and a base (e.g., base  60 ) of the device to an open position to provide access to the blending chamber. A user may open the blending chamber by moving the lid relative to the base. As examples, a user may rotate, translate, and/or pivot the lid relative to the base. In some examples, the opening the blending chamber may include decoupling the lid from the base. 
     At  404 , a user may place a capsule (e.g., solid-shell cosmetic ingredient capsule  300 ) into the blending chamber. As described previously, the user may place the capsule in a bowl-shaped depression (e.g., bowl-shaped depression  64 ) of the base. Optionally, the user may place the capsule into a cosmetic ingredient receptacle (cosmetic ingredient receptacle  150 ) that may line the bowl-shaped depression and/or may be selectively removed from bowl-shaped depression. The user may insert a single capsule in the blending chamber, or may place more than one capsule in the blending chamber, such as two, three, four, and/or five capsules in the blending chamber. 
     A user may close the blending chamber at  406 . In particular, the closing the blending chamber may comprise adjusting the lid and the base to the closed position. As discussed previously, this may include rotating, translating, and/or pivoting lid  20  relative to base  60 . The closing the blending chamber optionally may comprise crushing the capsule at  408 . In particular, when adjusting the lid and the base to the closed position, a blending element (e.g., blending element  22 ) of the lid may crush the capsule. The crushing may include squashing, crushing, breaking, and/or otherwise deforming the capsule. In particular, the crushing may include crushing a shell (e.g., shell  302 ) of the capsule to permit leakage and/or spillage of a cosmetic material (e.g., cosmetic material  317 ) to the bowl-shaped depression. 
     Optionally at  410 , methods  400  may include identifying a characteristic and/or identity of the capsule. As discussed, the physical characteristic and/or identity characteristic of the capsule may be identified by a controller (e.g., controller  172 ) based on input from the user and/or based on measured parameters. For example, the controller may determine a weight of the capsule via a weight sensor and/or may determine an identity characteristic of the capsule based on a unique identifier (e.g., RFID tag, barcode, etc.) of the capsule. Additionally or alternatively, a user may input one or more characteristics of the capsule via a user input device (e.g., user input device  210 ). 
     At  412 , methods  400  may include heating and blending the capsule to produce a cosmetic liquid (e.g., cosmetic liquid  330 ). In particular, methods  400  optionally may include initiating the heating and blending at  414 . As discussed, the heating and blending may be initiated by a user via input from user input device  210  and/or may be initiated autonomously by the controller based on sensed conditions (e.g., the lid and the base being adjusted to the closed position and the capsule being positioned in the bowl-shaped depression). During the heating and blending, methods  400  optionally may include adjusting the heating and blending. As described, the controller may adjust the heating and blending, as indicated at  416 , based on feedback from one or more sensors. For example, the controller may reduce electric power to a thermal element (e.g., thermal element  110 ) when the sensed temperature is too hot (greater than a threshold/set point or range) and/or increase electric power to the thermal element when the sensed temperature is too low (lower than a threshold/set point or range). As another example, controller  172  may increase electric power to an electric motor (e.g., electric motor  121 ) when a rotational speed of the electric motor and/or the blending element is too low and/or when a measured static torque applied to the blending element is too high (greater than a threshold/set point or range) and/or decrease electric power to the electric motor when the rotational speed of the electric motor and/or the blending element is too high and/or when the measured static torque on the blending element is too low (less than the threshold/set point or range). As described, the heating and blending process may be referred to as a blending cycle. 
     Additionally or alternatively, the set points/thresholds may be adjusted throughout the course of a blending cycle such that the heating and/or blending during a blending cycle may not be uniform and/or may vary throughout the course of the blending cycle. In some examples, and as described above, at the beginning of a blending cycle, only heating may be performed and the drive mechanism may be powered off. Additionally or alternatively, when the drive mechanism is powered on (e.g., after the initial heating-only period), the speed of the drive mechanism may be gradually increased in power until it reaches a maximum rotational speed. Additionally or alternatively, at the end of a blending cycle, the drive mechanism may be powered off and cooling may be performed before the blending cycle terminates. 
     When the heating and blending is complete, and the cosmetic liquid has been produced (the capsule has been melted and blended to form a homogenous liquid mixture), the blending cycle may be over. The user optionally may open the blending chamber at  418  and apply the cosmetic liquid at  420 . For example, the user may apply the cosmetic liquid to one or more of the user&#39;s skin, hair, and/or nails. 
     Methods  400  may include adding one or more auxiliary cosmetic materials to personalize cosmetic liquid  330 . As examples, the one or more auxiliary cosmetic materials may include one or more liquids, powders, and/or oils that may be configured to add a desired effect to cosmetic liquid  330 , such as to add and/or change a pigmentation, texture, viscosity, fragrance, etc., of cosmetic liquid  330 . In some examples, the auxiliary cosmetic materials may include one or more of a pigment, dye, and/or fragrance. One specific example of an auxiliary cosmetic material includes dry water. The one or more auxiliary cosmetic materials may be added to the blending chamber by a user before the heating and blending (e.g., such as at  404  when a user places a capsule into the blending chamber) and/or after the heating and blending (e.g., such as when the user opens the blending chamber to reveal cosmetic liquid  330  at  418 , but before the user extracts the cosmetic liquid). 
     Turning to methods  450 , at  451 , the methods  450  may comprise forming a portion of the shell. Forming the portion of the shell optionally includes preparing a liquid shell material at  452  (e.g., melting the components of shell  302 ), tempering the liquid shell material at  454 , and/or dispensing the liquid shell material into a mold at  456 . Preparing the liquid shell material may include melting the components of the shell (e.g., fats  306 , waxes  308 , resins  310 , crystal promoters  312 , chemically inert materials  314 , and/or active ingredient  320 ) and blending them together in a vat or other container. In some examples, the active ingredient may be melted and blended together with the other components prior to the dispensing. However, in other examples, the active ingredient may be added after the liquid shell material is dispensed into the mold at  460 , as discussed below. 
     Tempering the liquid shell material may include repeatedly alternating between heating and cooling the liquid shell material. Tempering the liquid shell material may encourage crystal formation in the liquid shell material when the liquid shell material solidifies. Dispensing the liquid shell material may include injecting, pouring, and/or otherwise dispensing the liquid shell material into the mold. The mold may include a plurality of depressions configured to produce a plurality of the capsules at a time. The dispensing may include dispensing the liquid shell material into all of the depressions simultaneously, or sequentially dispensing the liquid shell material into a predetermined number (i.e., a subset) of the depressions until all of the depressions are filled with the liquid shell material. In some examples, the forming the portion of the shell additionally or alternatively may include hardening, solidifying, and/or otherwise cooling the liquid shell material after it has been poured into the mold. 
     At  460 , methods  450  include adding a cosmetic material (e.g., cosmetic material  317 ) to the portion of the shell. The cosmetic material may be poured, injected, and/or otherwise dispensed into the portion of the shell formed at  451 . Further, the adding the cosmetic material may include adding the personal care ingredient and/or the active ingredient into all of the shell portions concurrently (at the same time), or sequentially adding the personal care ingredient and/or active ingredient into a predetermined number (i.e., a subset) of the shell portions until all of the shell portions are filled with, or filled with a predetermined amount of, the personal care ingredient and/or active ingredient. 
     As described, the active ingredient also may be added to the portion of the shell at  460 . In some examples, the active ingredient may be added to all of shell portions in the mold. However, in other examples, the active ingredient may be added to only a subset of the shell portions in the mold. Additionally or alternatively, the same and/or different amounts of the active ingredient may be added to the shell portions for which active ingredients are added. In this way, some of the shell portions may not include any of the active ingredient, and even the shell portions that include the active ingredient may include varying concentrations and/or amounts of the active ingredient. However, in other examples, the same amount of the active ingredient may be added to all of the shell portions. The active ingredient may be added concurrently with the personal care ingredient, or sequentially before or after the personal care ingredient. 
     At  462 , the methods  450  include forming the remaining portion of the shell. The remaining portion of the shell may be a bottom portion of the shell. Thus, the portion of the shell formed at  451  may include a top and sidewalls that are sufficient to hold the cosmetic material, and the remaining portion may be a bottom portion of the shell. Other options are within the scope of the present disclosure, such as in which the portion formed at  451  includes a bottom and sidewalls, and with the remaining portion being a top portion of the shell. The remaining portion of the shell may cover the cosmetic material and/or fully enclose and fluidly seal the cosmetic material. The remaining portion of the shell may be formed in the same and/or similar manner to the portion of the shell at  451 . Methods  450  optionally include cooling and/or hardening the shell at  464 . The cooling and/or hardening may include actively cooling the shell, such as with a refrigerator or other refrigerating device, and/or passively cooling the shell, such as by leaving the shell to cool at ambient (i.e., room) temperature. The cooling and/or hardening at  464  and/or the tempering at  454  may include forming crystals in the shell. Forming crystals in the shell may shrink the shell slightly, which may help release the shell from the mold at  466 . 
     At  466 , methods  450  may include removing the solid-shell cosmetic ingredient capsule from the mold. Methods  450  may include forming a unique identifier on the capsule and/or decorating the capsule at  468 . Decorating may include etching images and/or designs on the surface of the capsule, and/or coupling auxiliary decorations to the outside of the capsule (e.g., ribbons, glitter, etc.). As described, when the unique identifier comprises a barcode, QR code, or other optical indicia, forming the unique identifier may comprise printing, etching, or otherwise impregnating the unique identifier on the surface of the capsule. In some such examples, the unique identifier may include pigmented shell material. When the unique identifier comprises an RFID tag or other electromagnetic tag, the forming the unique identifier may comprise inserting and/or implanting the unique identifier into the capsule and/or otherwise coupling the unique identifier to the capsule. At  470 , methods  450  optionally include packaging the capsule in packaging (e.g., packaging  340 ). One or more (e.g., a plurality) of the capsules may be packaged together in the packaging to form a kit (e.g., kit  290 ), as will be described in greater detail herein. The kit may include varying proportions of capsules having the active ingredient (e.g., 100%, 50%, 25%, etc., of the capsules may include the active ingredient) and/or capsules having varying concentrations of the active ingredient (i.e., of the capsules in the kit that include the active ingredient, some may include higher or lower concentrations of the active ingredients than others). 
     As illustrated in  FIG.  12   , one or more of the solid-shell cosmetic ingredient capsules may be packaged together in packaging  340  to form a kit  290 . Thus, kit  290  may include packaging  340  and one or more solid-shell cosmetic ingredient capsules  300 . Kit  290  may be configured to provide a regimented dosage schedule for active ingredient  320 . Kit  290  may also be referred to as cosmetic kit  290 , capsule-containing kit  290 , tolerance building kit  290 , and/or dosage scheduler  290 . Packaging  340  may be configured to receive, contain, support and/or otherwise hold a single solid-shell cosmetic ingredient capsule  300  or a plurality of solid-shell cosmetic ingredient capsules  300 . As an example, and as illustrated in  FIG.  12   , in addition to solid-shell cosmetic ingredient capsule  300 , packaging  340  may include a second solid-shell cosmetic ingredient capsule  300 , a third solid-shell cosmetic ingredient capsule  300 , etc. However, the packaging may include more than three solid-shell cosmetic ingredient capsules in other examples. In particular, the packaging  340  may be configured to include at least two solid-shell cosmetic ingredient capsules  300 , at least four solid-shell cosmetic ingredient capsules  300 , at least six solid-shell cosmetic ingredient capsules  300 , at least eight solid-shell cosmetic ingredient capsules  300 , at least twenty solid-shell cosmetic ingredient capsules  300 , and/or at least thirty solid-shell cosmetic ingredient capsules  300 . As further examples, the packaging may include a week&#39;s, two weeks&#39;, or a month&#39;s supply of solid-shell cosmetic ingredient capsules  300  (e.g., 7, 14, or 28, 29, 30 and/or 31 solid-shell cosmetic ingredient capsules for a one-a-day dosage). 
     Capsules  300  may be precisely arranged and/or ordered in packaging  340 , or capsules  300  may be randomly positioned within packaging  340 . As examples, capsules  300  may be arranged in rows and/or columns in packaging  340 . Additionally or alternatively, packaging  340  and/or capsules  300  may include numbering or other ordering schemes that are configured to indicate to a user the order in which to utilize the capsules of packaging  340  and/or a frequency with which to consume the capsules (e.g., one a day, two a day, three a day, etc.). Packaging  340  may include the unique identifier of capsule  300  and/or other identity and/or physical characteristics of the capsules in packaging  340 . 
     As described above, packaging  340  may include multiple capsules  300  to form kit  290 . Kit  290  may include at least one kit  290 , at least two kits  290 , at least three kits  290 , at least four kits  290 , at least five kits  290 , and/or at least six kits  290 . When kit  290  includes more than one kit, the kits may be referred to as regimented dosage scheduler  290 . Additionally or alternatively, when kit  290  includes more than one kit, the kits may be packaged together or separately. In some examples, one kit  290  may comprise a single discrete packaging  340 , such that different kits  290  are physically distinct packages. Additionally or alternatively, capsules  300  may be included in packaging  340  of each kit  290  in different orders, combinations, numbers, and/or types to form different kits  290 . As an example, the capsules in different kits  290  may include different dosages of the active ingredient. In this way, a user may increase their intake of the active ingredient by purchasing kits  290  including capsules  300  having increasingly higher dosages of the active ingredient and/or by purchasing kits  290  containing a greater number of capsules that include the active ingredient (so that the user applies the active ingredient more frequently). 
     Thus, kit  290  may be configured to provide a regimented dosage schedule for active ingredient  320 . In some examples, the concentration of active ingredient  320  in each kit  290  may be different. As one such example, a first kit may include a lower first concentration of the active ingredient, a second kit may include an intermediate second concentration of the active ingredient, and a third kit may include a higher third concentration of the active ingredient. However, in other examples, kits  290  may include more or less than three tiers of active ingredient concentrations. For example, a set of kits  290  designed for monthly use may include four kits  290 , one for each week of the month. A user may first consume the solid-shell cosmetic ingredient capsules of the first kit containing the lower first concentration of the active ingredient, and after finishing the solid-shell cosmetic ingredient capsules of the first kit, then may transition to using the second kit containing the intermediate second concentration of the active ingredient, and then after finishing the solid-shell cosmetic ingredient capsules of the second kit, may transition to using the third kit containing the higher third concentration of the active ingredient. In this way, a user may build up the user&#39;s tolerance to the active ingredient over time, and the user may periodically increase the dosage of the active ingredient by purchasing kits  290  containing increasingly higher concentrations of the active ingredient. Thus, kits  290  may provide a regimented dosage schedule that may allow a user to gradually increase or decrease the dosage of the active ingredient over time. For example, capsule  300  with retinol, acne medication (e.g., salicylic acid), steroids, or another prescription ingredient as an active ingredient may be packaged in such a manner. Additionally or alternatively, the kits may permit a user to taper off an active ingredient by, for example, purchasing kits having successively lower dosages of the active ingredient. As an illustrative example, a kit containing salicylic acid (SA) and/or retinol may include solid-shell ingredient capsules containing 0.5-2% SA and/or 0.1-3% retinol, by weight, with a subsequent kit in a series of kits optionally including greater concentrations of SA and/or retinol than a prior kit in the series, (with some of the capsules not having any SA and/or retinol, and instead configured to calm the skin), and with the last kit in the series optionally including the same or a lower concentration of SA and/or retinol than the first kit in the series. 
     Additionally or alternatively when kit  290  contains one or more capsules  300  having the active ingredient, not all of the capsules in the kit may contain the active ingredient, and/or the capsules in the kit may contain different concentrations of the active ingredient. Thus, not all of the capsules in kit  290  may contain the active ingredient. Stated slightly different, the capsules containing the active ingredient may be spaced out in a kit, with capsules devoid of the active ingredient (i.e., active-free capsules) interspersed in-between the active-containing capsules. Thus, kit  290  may include one or more of a first subset of capsules that contain the active ingredient, a second subset of capsules that do not contain the active ingredient, and/or a third subset of capsules that contain a different active ingredient than the first subset of capsules. 
     When active-free capsules are included in kit  290 , these active-free capsules may be configured to minimize and/or mitigate the side effects of the active ingredient. In particular, they may be configured to nourish, hydrate, calm, replenish, moisturize, soothe, and/or otherwise provide a break from the active ingredient. In this way, the kits may help a user build up a tolerance to the active ingredient, while minimizing the side effects of the active ingredient. For example, if kit  290  contains an active ingredient that may cause redness, dryness, or irritation of a user&#39;s skin, such as may be caused by retinol and/or some acne medicines, a kit may include a series of solid-shell cosmetic ingredient capsules that include this active ingredient, and one or more solid-shell cosmetic ingredient capsules that do not include this active ingredient. As a further example, the solid-shell cosmetic ingredient capsule(s) may include different active ingredients that may be configured to calm, reduce inflammation, reduce redness, hydrate the user&#39;s skin, and/or otherwise offset the side effects of the other active ingredients. 
     As examples, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 50%, at least 75%, at most 100%, at most 80%, at most 75%, at most 70%, at most 65%, at most 60%, at most 55%, at most 50%, at most 45%, at most 40%, at most 35%, and/or at most 30% of the capsules in kit  290  may not include the active ingredient. When the kit includes a mixture of active-ingredient-containing capsules and active-free capsules, the capsules may be arranged and/or ordered in an alternating pattern/order. That is, the active-free capsules may be interspersed between the capsules containing the active ingredient. In particular, the capsules containing the active ingredient may be spaced apart from one another at regular intervals in packaging  340  by the capsules not containing the active ingredient. As examples, the capsules containing the active ingredient may be every second, every third, every fourth, every fifth, and/or every sixth capsule in packaging  340 . In between each active-ingredient-containing capsule  300 , a cleansing capsule and/or a calming capsule may be included. These capsules not containing the active ingredient may include only personal care ingredient  318 . Thus, different capsules that serve different purposes and/or provide different desired effects may be included within the same kit. By including capsules without the active ingredient in between the capsules with the active ingredient (i.e., by spacing out the capsules with the active ingredient), undesirable side effects of the active ingredient may be reduced, providing a more soothing, less irritating user experience if the particular active ingredient has a propensity for causing an undesirable side effect. 
     In some such examples, the capsules of a given kit having the active ingredient may comprise at least approximately the same concentration of the active ingredient. Specifically, the relative concentrations of active ingredient  320  in the solid-shell cosmetic ingredient capsules  300  of a given kit may vary by no more than 10%. As an example, when the average concentration of active ingredient  320  in the solid-shell cosmetic ingredient capsules of a kit is 2% by mass, the percent by mass of the active ingredient in each solid-shell cosmetic ingredient capsule  300  may vary between 1.9% and 2.1% (plus or minus 5% of the average 2% by mass) amongst the various solid-shell cosmetic ingredient capsules of the kit. However, in other examples, the capsules of a given kit having the active ingredient may have different concentrations of the active ingredient. Specifically, the dosage of the active ingredient within a given kit may increase, rather than, or in addition to, increasing between different kits.
