  • 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 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 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 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.
