BACKGROUND OF THE INVENTION
The skin acts an a protective barrier from the external environment. When damaged, a cascade of events is triggered to repair to the damaged tissue. Wound healing is a complex process, progressing through four stages (inflammation, proliferation, remodeling, and epithelialization) to repair the damaged area. Although wound healing is a natural process, disruption of the events involved may lead to incomplete healing and further damage to the tissue. Current methods of treating wounds include applying a dressing to the wound to stem bleeding, prevent infection and encourage healing. Wound dressings are often made from breathable material (for example, gauze). Occlusive dressings have been used on wounds, but the effects of occlusion on wounded skin are not completely understood (see e.g., Leow and Mailbach; J Dermatol Treat, (1997) 8, 139-142).
However, current methods of using occlusion on wounded skin is unsatisfactory because current occlusive dressings are not durable, convenient, or long lasting. Moreover, some current occlusive coverings require subjects to wrap plastic around the area to be treated, lowering subject compliance because the treatment is cumbersome and uncomfortable. Lastly, current occlusive coverings do not permit the exposure of the wound to the environment to be modulated based upon the nature of the wound. For example, current occlusive dressings are designed to exclude both air and water, and generally it is not possible to permit exposure to one and not the other.
Headaches cause pain in the head and neck and arise from a myriad of causes. While most are not life-threatening, headaches can be very painful and debilitating. Headache remedies include from over the counter analgesics, prescription medications, acupuncture and massage.
The commercially available polymer materials used in therapeutic products today do not necessarily provide the elasticity, environmental resistance and skin adhesion for long lasting product performance nor do they provide the aesthetic feel and appearance required by the consumer of therapeutic products.
SUMMARY OF THE INVENTION

In some embodiments, the therapeutic film has an appearance of natural skin upon application to the skin. The language “appearance of natural skin” includes the perception that the therapeutic film, when applied to the skin, has the look, feel and texture of real skin and that the film treated skin has the physical properties (e.g., the elasticity and stiffness) of real (e.g., live) skin. A trained observer and/or a technician would be able to determine whether the film upon application to the body has the appearance of natural skin. For example, a trained observer would be able to determine whether the film, upon application to the body, appears excessively shiny, as described in Example 3, or whether the film appears not to move with the underlying musculature of the skin by, for example, breaking, buckling or deforming, in response to natural skin motion.
A technician would be able to determine whether the film has the appearance of natural skin upon application to the body. For example, the elasticity and stiffness of skin, with or without the therapeutic film applied to it, can be assessed by a wide variety of methods (Agache et al., Arch. Dermatol. Rev., 269 (1980) 221, the teachings of which are incorporated herein by reference). For example, the DermaLab suction cup instrument provides one common method to assess the mechanical properties of skin, and has previously shown younger skin to be less stiff and more elastic than aged skin (Grahame et al. Clinical Science 39 (1970) 223-238, the teachings of which are incorporated herein by reference). With this method, the stiffness of the skin is indicated by the Young's Modulus, a measure calculated by the instrument based on the pressure required to suck skin up a predetermined distance.
In some embodiments, the Young's Modulus of the skin treated with a therapeutic formulation is reduced by between about 5% to about 70%, for example, between about 30% and about 60%, or between about 40% and about 50% compared to untreated skin. In some embodiments, the Young's Modulus of skin treated with a therapeutic formulation is reduced by between about 5% and about 25% compared to untreated skin.
The elasticity of the skin is determined by the skin retraction time. The retraction time is obtained by measuring the time it takes for the skin to drop a predetermined distance towards its natural position, after the suction pressure is removed. In some embodiments, the retraction time of skin treated with a therapeutic formulation is decreased by between about 5% and about 75%, for example, between about 30% and about 60%, or about 50% and about 65% when compared to untreated skin. In some embodiments, the retraction time of skin treated with a therapeutic formulation is decreased by between about 5% and about 10% compared to untreated skin. In some embodiments, the retraction time of the skin treated with the film approaches the retraction time of the film alone.
The skin of the bicep and hand was evaluated before and after the therapeutic treatment was applied, as shown in FIGS. 1 and 2. The DermaLab results confirmed that the skin was less stiff (FIG. 1) and more elastic (FIG. 2) after product application. The observed reduction in stiffness and the increase in skin elasticity are consistent with skin being more youthful.
The language “the film is formed” and “film formation” includes the results of the polymerization reaction that occurs upon the interaction of the reactive reinforcing component and the cross-linking component. Without being bound by theory, film formation is characterized by a phase transition from the viscous sol state of a mixture to that of a continuous interconnected polymer state of film.
A technician could determine when the film is formed on the body by using routine methods. For example, rheological measurements using, small amplitude oscillatory shear can determine the continuous evolution of the viscoelastic properties, such as elastic modulus (G′), the viscous modulus (G′′) and the loss of tangent (tan δ) of the reacting mixture continuously through the film formation process. In some embodiments, the rheometer can be used to determine the cross over time between G′ and G′′ and the time when tan δ becomes frequency independent, which is a measure of film formation. In some embodiments, the film is formed within at least about five minutes, for example, within about one minute, about two minutes, about three minutes or about four minutes. In some embodiments, the film is formed within at least about 10 seconds and about 3 minutes.
In some embodiments, the skin or therapeutic film has a Young's Modulus (e.g., tensile strength) of between about 0.01 and about 1 MPa, as illustrated in Example 1.
In some embodiments, the fracture strain of the skin or body corrective film has a fracture strain of at least about 150%, as measured by Example 1.
In some embodiments, the therapeutic film has a leather adhesive force of greater than about 20 N/mm, for example, greater than about 25 N/mm, greater than about 30 N/mm, greater than about 35 N/mm, greater than about 40 N/mm, greater than about 45 N/mm, greater than about 50 N/mm, greater than about 55 N/mm, greater than about 60 N/mm, greater than about 65 N/mm, greater than about 70 N/mm, greater than about 75 N/mm, or greater than about 80 N/mm, as determined by the leather adhesion test illustrated in Example 2. In one embodiment, the leather adhesive force is between about 50 and about 80 N/mm, as determined by the leather adhesion test illustrated in Example 2.
In some embodiments, the therapeutic film has a hysteresis of less than about 10% for example, least than about 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, less than about 2%, less than 1% or about 0%.
In some embodiments, the therapeutic film is between about 10 μm and about 1500 μm thick, for example, between about 50 μm and about 500 μm thick. In some embodiments, the film is less than about 100 μm thick. The film thickness may be measured by methods known to one of skill in the art, for example, by the combination of calipers and a calibrated microscope. The thickness of the film may also be digitally measured from a micrograph of the film cross-section. The microscope calibration allows for the conversion of measured pixelar distance into metric distance units.
In some embodiments, the therapeutic film shrinks by less than between about 1 and 30%, for example, between about 1 to about 15%. The amount of shrinking may be determined by methods known to one of skill in the art, for example, by the Croll method (Croll, S. G. J. Coatings Tech. 52 (1980) 35, the teachings of which are incorporated herein by reference). In this method the film is used to coat one side of a thin flexible substrate. The amount of curve developed in the substrate due to the shrinking of the coating is used to calculate the magnitude of shrinking of the coating (Francis et al., J Mater Sci 2002; 37:4717-31, the teachings of which are incorporated herein by reference.)
In some embodiments, the therapeutic films are physiologically stable. The language “physiologically stable” includes the durability of the film upon exposure to normal skin conditions, for example, humidity, tears, sweat or sebum. The physiological stability may be determined by methods typically used by one of ordinary skill in the art, such as an uptake test, which measures the change in weight of the film after exposure to a physiological factor. For example, the uptake test may employ a formulation of simulated sweat (e.g., 1× phosphate buffered saline solution) or simulated sebum (e.g., 25% wax monoesters, 41% triglycerides, 16% fret fatty acids and 12% squalene). In some embodiments, the weight of the film increases by less than about 10%, for example, less than about 9%, less than about 8%, less than about 7%, less than about 6% less than about 5%, less than 4%, less than 3%, less than 2%, less than 1% or exhibits no increase upon exposure to humidity, tears, sweat or sebum.
In some embodiments, the invention pertains, at least in part, to methods for treating wounds, comprising applying to a wound on a subject a formulation comprising a) a first reactive reinforcing component; and b) a second cross-linking component; wherein the cross-linking component catalyzes an in situ cross-linking of the reactive reinforcing component, such that a film is formed on the on the wound, thereby treating the wound. The language “treating a wound” includes protecting the wound from damage while healing, for example, by providing a barrier from environmental elements, such as bacteria, viruses, dirt and the like. In some embodiments, the wound is the site of a skin biopsy. In some embodiments, the wound is not a topical disorder, such as lichen simplex chronicus, cutaneous lupus, psoriasis, eczema, acne, hypertrophic scars, warts or chronic dry skin.

EXAMPLES
Example 1
Cyclic and Extension Pull Test
Sample Preparation:
For the purpose of bulk mechanical property determination, target materials were cast inside dumbbell shaped molds. The dimensions of the neck of the mold were 20 mm in length, 5 mm in width and 1.5 mm in depth. The “handles” of the mold were 20 mm by 15 mm and provided adequate area to insure secure slip-free grip during testing. The mold dimensions are consistent with the ASTM D638 guidelines.
Once the poured specimens were fully cured and dried, the formed samples were extracted from their individual molds by means of a spatula and the geometry of the finished pieces was measured with digital calipers to determine precise dimensions.
Mechanical Testing:
Mechanical characterization of specimens was carried out on the Instron 3342 (Instron, Norwood Mass.) equipped with LOON load-cell (Instron #2519-103). Dumbbell shaped samples were mounted onto the instrument via modified Instron 2710-101 grips which insured sample didn't slip or fail inside the grips during testing. Two types of tests were performed sequentially on each sample, first the Cyclic Test followed by the Extension Pull Test. It is noted that the first test (e.g., the cyclic test) had negligible effects on the result of the second test (e.g., the extension pull test). Each test was preprogrammed into Bluehill Lite Software used to operate the instrument. The parameters and data analysis associated with each of the two tests is described below.
Cyclic Test:
In order to determine the elasticity of the materials, a cyclic test was designed. The cyclic test was used to determine the most elastic (e.g., spring-like) material and an Instant Residual Strain (I.R.S.) was obtained from this test, as described below. Generally, the more elastic the material, the faster it returns to its original shape after deformation. For perfectly elastic materials, the I.R.S. and cycle test area approach zero, and therefore, the lower the value the better.
Prior to starting the test, a sample was mounted onto the instrument such that the rectangular handle portions of the specimen and none of the specimen neck were fixed within the instrument grips. The instrument grip distance was adjusted such that the sample was at neutral extension as indicated by the instrument force being close to zero (±0.01N). Subsequently, cyclic extension was performed at 1 mm/s to a maximum extension of 15% of initial sample length. A total of 15 cycles are executed and recorded. The stress strain data recorded by instrument was exported into Excel where the reported mechanical properties were calculated.
An Excel template was used to automatically extract a number of parameters. The cyclic Young's Modulus as calculated as the straight line slope of the stress-strain curve of first cycle between 1% and 4%. The R squared value of the linear fit was above 0.99 or the Young's Modulus was discarded. The Instant Residual Strain (I.R.S.) was calculated for each cycle as the strain difference between the loading and unloading curves at half the maximum stress achieved during the 1st cycle. The I.R.S. for the first cycle as well as the average I.R.S. for the 4th through 14th cycles were recorded. The area bound by the loading and unloading curves of each cycle was also calculated. Good agreement was observed between the I.R.S. and the calculated cycle area.
The majority of the materials evaluated were sufficiently flexible and elastic such that the Cyclic Test could be repeated on the same sample without a significant change in calculated properties. This suggests this test does not result in long lasting changes to the tested material.
Extension Pull Test:
The Extension Pull test was used to determine the stiffness and stretchiness of a material by measuring the Young's Modulus and Ultimate Strain. The Young's Modulus was utilized as a measure of material stiffness, while the Ultimate Strain was used as a measure of material flexibility. In order to develop a film with the appearance of skin, the Young's Modulus should fall within a target range (e.g., 0.1-1.0 MPa), while the fracture strain (as measured by the Ultimate Strain) should be sufficiently high (e.g., greater than about 150%) so that the film will not break when being deformed by skin movement.
The sample was mounted onto the instrument such that the rectangular handle portions of the specimen and none of the specimen neck were fixed within the instrument grips. The instrument grip distance was adjusted such that the sample was at neutral extension as indicated by the instrument force being close to zero (±0.01N). Subsequently, extension until sample failure was performed at 10 mm/s. The stress strain data recorded by instrument during the extension was exported to Excel where the reported mechanical properties were calculated.
An Excel template was used to automatically extract a number of parameters from the instrument generated data. The extension Young's Modulus (YM) as calculated as the straight line slope of the stress-strain curve between 6% and 11%. The R squared value of the linear fit was above 0.99 or the Young's Modulus was calculated from a more linear 5% strain range on the stress strain curve. The Shear Modulus (C) was determined from the same strain range as the YM. G was calculated as the slope of the best line fit between recorded stress and α-α-2, where α is 1 plus the instantaneous strain. The Yield strain was determined as the strain at which the measured stress differed by more than 10% from the Neo-Hookean stress; the multiple of G and (α-α-2). Ultimate Stress was calculated as the maximum stress recorded during the experiment. The mechanical property calculations presented here are consistent with ASTM D412.
Example 2
Leather T-Peel Adhesion Test
To determine adhesiveness of the target materials, the materials were spread onto a piece of soft flexible leather 25.4 mm wide and 76.2 mm long. The leather used as test substrate was light weight upholstery leather (AD1100 from Leather Unlimited, Belgium Wis.). Immediately after spreading the material onto the first piece of leather, a second equivalent piece of leather was placed on top to sandwich a thin layer of material between the two pieces. The two pieces of leather were pressed together to leave a thin homogeneous layer of material at the interface of the two leather substrates. The edges were wiped to remove access materials and the material was allowed to cure and dry to form a test specimen.
The adhesion test sample was partially pealed at one end by hand to separate enough of the two leather substrates for effective grip by Instron 3342 mounts. Each leather substrate was secured in its own instrument grip and an extension test was performed at a rate of 10 mm/s to peel the two substrates from each other. The force vs. time data was recorded by instrument during the extension and exported to Excel where the reported adhesive force was calculated.
An Excel template was used to automatically extract adhesive parameters from the instrument generated data. The sample average adhesive force was calculated by averaging the instantaneous force measured by the instrument during the experiment normalized by the sample width (25.4 mm). This test method was developed in accordance with ASTM D1876. The minimum acceptable adhesion, which depends on the stiffness of the material and the area on which the film is placed, was approximately greater than 25 N/mm
Example 3
Image Analyses Measures
Shine:
In order to measure shine, either in vitro or in vivo, a light box with a light source placed at a 45° angle relative to the site being measured was used to create shine, and a camera, positioned such that the angle formed by a line drawn from the lens to the area being measured is 45°, was used to photograph the site. The white balance, F-stop and ISO of the camera were manually fixed at set values to give adequate exposure and good color temperature. One picture was taken without any diffusing element between the light source and the site to capture the shine. Then, a diffusing surface was placed between the light source and site and another photograph was taken (altering shutter speed such that the exposure is similar or equal to the first photograph). This photograph captured the surface without any shine present while the first photograph captured the maximum amount of shine as a result of specular reflectance. These photographs were overlaid and cropped to the relevant sample area and then the diffused photograph was subtracted from the maximum shine photograph to create a photograph with only the shine highlights present. The entire subtracted photograph was then summarized by finding the average grey value along with the standard deviation. This average grey value was denoted as the shine value and was used to compare the amount of specular reflectance present in each sample. For each sample, the camera settings for each situation (with and without the diffuser) were identical.
Photo Set Up Capture:
To ensure maximum repeatability in panelist placement for every photograph taken for product performance evaluation, a Head Positioning System (HPS) was created. This HPS had two configurations: forehead-only evaluations and a whole face evaluation. In both configurations, a model 819 series table clamped chin-rest from Applied Science Laboratories (ASL) was used as a base to mount the two different configurations to a table. Two cameras were used to capture the subject from two different angles. The first camera (normal shot) was positioned face-on such that line of the lens through the camera was positioned relative to the plane of the subject's face at an angle of approximately 90°. A second camera (45° shot) was positioned to the subject's left such that the line of the lens through the camera was positioned relative to the plane of the subject's face at an angle of approximately 45° capturing primarily the left side of the subject's face. The position of the cameras relative to the chin-rest was kept fixed. In the first configuration, an ASL cheek-rest (819-2155) was mounted to the ASL chin-rest. In this setup, the panelist's head was positioned such that the line formed from the center of the camera lens to the area of evaluation is normal to the area of evaluation on the forehead. In the second configuration, an ASL forehead-rest (819-2150) was attached to the chin-rest. In this setup, the chin-rest cup was positioned such that the horizontal bar on the forehead-rest was situated at the panelist's horizontal hairline, maximizing the area of evaluation in every photograph.
Lighting for the photography consisted of two Calumet Quattro fluorescent lamps (CF0003) with four Calumet 35 Watt 5500K daylight color temperature fluorescent lights (OL2003) placed in front of and on either side of the panelist, angled to point directly at the panelist. A glare stop polarizing filter from Visual Pursuits, Inc. was also placed on the front of each lamp. The lights were allowed to warm up for at least 10 minutes prior to taking any photographs. In addition to the lighting, a circular polarizing filter was used on each of the camera lenses to control the type of light in each photograph.
For each evaluation, two sets of pictures were taken for the normal shot camera. In the first set, the camera's circular polarizing filter was configured such that its polarization was parallel to the polarization of the fluorescent lights, giving a picture that highlighted the shine as well as the fine wrinkles, pores and skin texture. In the second set, the circular polarizing filter was configured such that the polarization was perpendicular (or cross) to the polarization of the fluorescent lights yielding a result that eliminated all glare and shows the underlying skin tone, discoloration, and deep wrinkles The 45° shot camera was configured for each evaluation such that the camera's circular polarizing filter was configured so that its polarization was parallel to the polarization of the fluorescent lights, giving a picture that highlighted the shine as well as fine wrinkles, pores and skin texture.
Brow-Lift Measure of Photo:
To measure the brow height of a photograph, a photograph was obtained using the method of photo capture previously described above. A “canthus line” was then drawn on the photograph from the medial to the lateral canthus on each eye. This canthus line was used as a base from which the brow height was measured. The eyebrow was isolated from the image by applying valley detection, edge detection and thresholding graphical operations on the image. Within one experiment, the parameters for valley and edge detection and thresholding were constant so that the same portions of the eyebrow from each image series was the same. To accurately isolate the eyebrow, these parameters were changed to account for differences in photographic exposure between experiments and skin and brow colors between panelists. From these methods, a binary mask was created which was then further manipulated in order to ensure only the eyebrows were isolated in the picture. For overall height change measurements, the center of mass of each eyebrow was then determined from its binary mask. The parameters for the binary operations and center of mass determination were always kept constant. The height of each brow was the normal from its center of mass to its corresponding canthus line. This method measured overall height change but did not capture the magnitude of change for severe arching or angling where portions were raised and portions were lowered. For such cases, instead of measuring the brow's center of mass, the heights of the brow normal to the canthus line at its left and right edges and at its center were determined from the binary mask.
Redness Reduction Photo Measure:
Photographs are obtained of the panelist using the photographic setup previously described. Comparisons of redness are only done on photographs taken within the same experiment because the exposure, and light and face positioning are only constant within a single experiment. After the series of photographs in the experiment are taken, the cross-polarized pictures are overlaid such that the area to be evaluated for redness reduction remains as fixed as is possible between each image. Using graphical manipulation software, the L*a*b* channels in the CIELAB colorspace are created for each image in the series. The L* value represents the degree of illumination, while a* and b* define the chromaticity. Specifically, a* represents the degree of redness (+values) or greenness (−values). The intensity of the red color square on the color card in the baseline photograph's a* channel is then used to normalize the subsequent images by adjusting the intensity of the subsequent image a* channels until the a* values within the red color square on the color cards in those images equals the baseline value. The area of evaluation is then cropped out of the photographs. Redness reduction is then determined by subtracting the a* values for the area in the ‘before’ photographs from the a* values in the ‘after’ photographs. A negative value from this subtraction indicates a reduction in redness while a positive value indicates an increase.
Example 4
Stress Testing Methods
The mechanical durability of the materials was evaluated by creating an artificial brow lift by applying one of the following methods of pre-tensioning the skin during product application. These methods of pre-tensioning were used to stress the skin surface and pull the brow into a lifted position:

    
    
        “brow orthogonal push,” in which a stress was applied that originated at the eyebrow and is vectored anteriorly away from the eyebrow at an angle that was between 80° and 100° relative to the line of the eyebrow,
        “corner hairline diagonal pull,” in which a stress was applied that originated at the most anterior and lateral point on the panelist's hairline and was vectored anteriorly away from and at an angle between 10° and 80° relative to the line of the eyebrow,
        “corner hairline orthogonal pull,” in which a stress was applied that originated at the most anterior and lateral point on the panelist's hairline and was vectored anteriorly away from and at an angle between 80° and 100° relative to the line of the eyebrow,
        “lateral hairline orthogonal push” in which a stress was applied that originated at the most lateral point of the hairline that was at or above the level of the eyes and was vectored anteriorly away from at an angle between 80° and 100° relative to the line of the eyebrow.
    
    


While the brow was held lifted by one of these stresses, the product was applied to the area of skin over which the tension was being applied. Once the film cured, the stress was removed and the mechanical durability of the film's ability to hold the tensions in the skin was evaluated. This evaluation was achieved by measuring the degree of brow lift using the methods described before and after product application. Durability of the effect was measured by allowing time, normal and exaggerated facial expressions and environmental stresses such as water, sweat, heat, sebum production and surface contact to interact with the film. The amount of lift was tracked at regular intervals to determine how quickly the film's ability to hold the mechanical benefit lasted. A film was determined to be mechanically durable if it could withstand the stresses previously mentioned and maintain the brow lift at the level originally achieved immediately after application.

Procedure:

Components 1-8 were mixed together and homogenized at 26,000 RPM for 10 minutes. After 10 minutes, component 9 was added and homogenized again for 10 minutes at 26,000 RPM. To this homogenized mixture, components 10-15 were added and mixed with an overhead stirrer at 2,000 RPM until homogenous in appearance (this is the siloxane phase). In a separate container, components 16-19 were mixed until homogenous to form the water phase. The water phase was added to the siloxane phase very slowly, with continuous stilling at 2,000 RPM. Once the water phase was completely mixed in, components 20 and 21 were added to the formula and mixed at 2,000 RPM until homogenous.

Example 6
Development of Cleanser to Remove Therapeutic Compositions
It was found that commercially available cleansers were not effective at removing the film formed upon application of the therapeutic compositions of the invention. To evaluate the performance of the cleansers, the film was applied to facial skin of volunteers. Following six to eight hours, the cleanser was rubbed onto the film and left on the film for 30 seconds. The subject was then instructed to remove the film with a towelette of a given surface roughness by gentle wiping the swollen film from the skin. The following commercially available products were tested:
Philosophy Purity Made Simple
Shiseido Benefiance Creamy Cleansing foam
Noxema
Estee Lauder Perfectly Clean Splash Away Foaming Cleanser
Makeup forever sens'eyes
Loreal go 360clean deep
Clinique naturally gentle eye makeup remover
Olay Total Effects 7 in 1 antiaging cleanser
Olay dual action cleanser and pore scrub
Garnier Skin Renew
Lancome Bi-Facil double action make-up remover
Neutrogena deep clean invigorating foaming scrub
Olay regenerist daily regenerating cleanser
CVS pharmacy deep cleansing makeup remover
Neutrogena Ageless essentials Continuous Hydration Cream Cleanser
CVS cleansing and makeup remover
Yes to cucumbers natural glow facial towelettes
As none of the aforementioned products were effective at removing the film, a cleanser was prepared to disrupt the mechanical integrity of the film and to facilitate the delivery of the cleanser components into the film. Without being hound by theory, the removal mechanism can be described in four steps with key formula components for each step indicated in parentheses:

    
    
        1. Film wetting (Silsoft 034, Silsoft ETS, 5CS dimethicone)
        2. Penetration of formula components (siloxane emulsifiers, siloxane phase, glycols, Cremaphor EL)
        3. Film swelling (Silsoft 034, Silsoft ETS, Isododecane, 5CS dimethicone)
        4. Film release from skin (glycols, water)
    
    


Silsoft 034, Silsoft ETS, 5CS dimethicone readily wet the surface of the film. The siloxane emulsifiers or the Cremaphor EL incorporate the aqueous phase into the siloxane phase, and may facilitate delivery of the film swelling components into the film. Silsoft 034, isododecane, and Silsoft ETS contribute to swelling the film and mechanical disruption. This enables penetration of the aqueous phase, hydration of the skin and reduction of the film's adhesion to the skin.
Tables 15-17, below, provide compositions that were effective in removing the film:

Viscosity Measurements
The viscosity of a fluid can be measured by many methods known to one of skill in the art. Specifically, “The rheology handbook: for users of rotational and oscillatory rheometers By Thomas G. Mezger” or ASTM standards such as ASTM D3835-08, ASTM D2857-95, ASTM D2196-10, and ASTM D2983-09 instruct one of skill in the an on how to measure the viscosity of a fluid. Illustrative methods also include the following methods:
Method A
I. Overview
This protocol determines the viscosity (cP) on a Brookfield Viscometer. This protocol can be performed on a wide variety of formulations including but not limited to immediate effects treatment, and perfector.

Example 8
Use of Compositions to Treat Headaches and Wounds
A. Headache Use:
The reactive reinforcing component formulation of the invention can be used to treat tension headaches. A representative formulation is provided below.
Application.
To treat the headache, apply an even layer of the formulation, approximately 0.05 g per square inch on to the forehead, covering the space between the hair line and the brows. Immediately afterwards, apply the crosslinking component on top, covering and extending past the area covered by the reactive reinforcing component. The crosslinking component can be applied at a concentration of approximate 0.1 g per square inch. Allow approximately 15 minutes for the applied formulations to set and form a visually pleasing film.
Effect of Film on Treatment Area.
The resulting film provides mechanical support that relieves the load on face and neck muscles that are responsible for tension headaches effectively relieving the headache. Within minutes to hours the muscles relax in response to the reduced load and the headache is reduced. The film should be worn for as long as headache relief is desired. To remove, a removal solution can be used. The product can be reapplied daily or as often as desired by repeating the procedure above.
Additionally, the support offered by the set formulations produces a brow lift. The brow lift improves the appearance of the eye and diminishes the eye obstruction by the brow (eye lid drooping) in some cases improving comfort and vision. The set formulations are cosmetically pleasing, visual unobtrusive, and provide a non-invasive solution to a tension headache without systemic chemical side effects associated with oral or injection medication.
B. Wound Use:
The reactive reinforcing component formulation of the invention can be used to treat a skin wound. A representative formulation for this use is provided below.
Application.
To treat the wound, apply an even layer of the formulation, approximately 0.05 g per square inch on top of and surrounding the wound that has been blotted dry. Immediately afterwards, apply the crosslinking component on top of the formulation, covering and extending past the area covered by the reactive reinforcing component. The crosslinking component can be applied at a concentration of approximate 0.1 g per square inch. Allow approximately 15 minutes for the applied formulations to set and form a visually pleasing film. The film should be worn for as long as the wound persists. To remove, a removal solution can be used. The product can be reapplied daily or as often as desired by repeating the procedure above.
Effect of Film on Treatment Area.
Within minutes to hours the skin relaxes in response to the reduced load and the wound healing time is reduced. The resulting film provides mechanical support that relieves the load on wound, reducing scar formation. Furthermore the film provides an occlusive protective covering for the wound that protects the wound from physical and chemical attack while it is healing. The film has hydration and biocompatibility properties that improve wound recovery. Furthermore the film aids the controlled sustained delivery of imbedded wound healing actives directly to the wound site. The film is comfortable and aesthetically unobtrusive aiding, thereby increasing subject compliance.
