Treatment for Lifting Upper Arm Lax Skin

Eligible patients will receive 2 treatments on both upper arms (4-6 weeks apart) using the Sofwave System.

Treatment may be administered after the enrollment and screening at the first visit, or it may occur later following the enrollment and screening activities based on site scheduling availabilities. All patients will return to the clinic for follow up visit at 3 months ± 2 weeks post last treatment (FU1).

Methodology described in the protocol to evaluate efficacy and safety of treatments will be carried out at each visit at the clinic.
