Brief summary: To evaluate the safety and effectiveness of the Allergan CoolSculpting® system using CoolAdvantage applicators for non-invasive subcutaneous fat reduction of the upper arms and inner thighs in participants of Chinese descent.


Eligibility criteria: Inclusion Criteria:

* Participant (healthy volunteers) has read and signed the study written informed consent form (ICF)
* 1st or 2nd generation, non-mixed race, Chinese descent.
* Participant has clearly visible and palpable fat on the left and right lower aspects of the upper arms and/or left and right inner thighs, which in the investigator's opinion is appropriate and may benefit from the treatment.
* Participant has not had weight change fluctuations exceeding 4.5 kilograms (kg) (or 5% of body weight) in the preceding month.
* Participant has a body mass index (BMI) of ≥ 18.5 to ≤ 30. A BMI is defined as weight in kilograms divided by height in meters squared (kg/m\^2).
* Participant agrees to maintain weight (i.e., within 5% of body weight) by not making any changes in diet or exercise routine during the course of the study.
* Participant agrees to have photographs taken of the treatment area(s) during the scheduled time periods.

Exclusion Criteria:

* Participant has a history of an invasive fat reduction procedure (e.g., liposuction, surgery, lipolytic agents, etc.), or implants in or immediately adjacent to the area of intended treatment.
* Participant has a history of prior surgery or scar tissue on the arms and/or inner thighs related to the area being considered for treatment.
* Participant has a known history of cryoglobulinemia, cold urticaria, cold agglutinin disease, or paroxysmal cold hemoglobinuria.
* Participant has a known sensitivity to cold or has any condition with a known response to cold exposure that limits blood flow to the skin, such as cold urticaria, Raynaud's disease, or Chilblains (pernio).
* Participant with a clinically significant bleeding disorder, or concomitant use of oral or subcutaneous anticoagulants, or is taking any medication that in the investigator's opinion may significantly increase the participant's risk of bruising.
* Participant with a history of carpal tunnel syndrome, compartment syndrome, or deep vein thrombosis in the upper or lower extremities.
* Participant is currently taking or has taken diet pills or weight control supplements within the past 6 months.
* Participant has any dermatological conditions, such as moderate to excessive skin laxity, infection, open wound, or scars in the location of the treatment sites that may interfere with the treatment or evaluation (stretch marks are not an exclusion).
* Participant has an active implanted device such as a pacemaker, defibrillator, drug delivery system, or any other metal-containing implant within or adjacent to the area being considered for treatment.
* Participant is pregnant or intending to become pregnant in the next 3 months.
* Participant is lactating or has been lactating in the past 6 months.
* Participant is unable or unwilling to comply with the study requirements.
* Participant is currently enrolled in a clinical study of any unapproved investigational device, investigational product, or any other type of medical research judged not to be scientifically or medically compatible with this study.
* Participant has any other condition or laboratory value that would, in the professional opinion of the investigator, potentially affect the participant's response or the integrity of the data or would pose an unacceptable risk to the participant.
* Participant has had a non-invasive fat reduction and/or body contouring procedure in the area(s) of intended treatment within the past 12 months.
* Participant needs to administer, or has a known history of subcutaneous injections, into the area(s) of intended treatment (e.g., cortisone, heparin, insulin) within the past 6 months.
* Participant with known sensitivity or allergy to fructose, glycerin, isopropyl alcohol, or propylene glycol.
* Participant with impaired peripheral circulation in the area to be treated.
* Participant with neuropathic disorders such as post-herpetic neuralgia or diabetic neuropathy.
* Participant with impaired skin sensation.
* Participant with a history of hernia in or adjacent to the treatment area(s) site.
* Participant with a skin condition such as eczema, dermatitis, or rashes in the area to be treated.
* Participant diagnosed with a systemic fibrosing disease or fibrosis in the area intended or adjacent to the area to be treated.
