Brief summary: Open-label, non-randomized, prospective, multi-center, self-controlled clinical study.

Detailed description: Eligible patients will receive combined treatment on both upper arms, included 1 or 2 SofWave treatments and 4 Pure Impact treatments. At the first session (Visit 1), subjects undergo SofWave treatment, and may undergo Pure Impact treatment also at the same visit. If conducting the two procedures on the same day, Pure Impact shall be applied before SofWave. If the procedures are done in separate visits, schedule the Pure Impact 2-7 days after the SofWave procedure. If the two treatments are conducted on the same day, then the second Pure Impact session will be 7-10 days after; similarly, the third and fourth Pure Impact sessions will be performed 7-10 days apart following the previous session. The last (fourth) Pure Impact treatment may occur on the same day or after the optional second SofWave treatment. If conducting the two procedures on the same day, Pure Impact shall be applied before SofWave. If the procedures are done in separate visits, schedule the SofWave 2-7 days after the fourth Pure Impact procedure.

All patients will return to the clinic for two follow-up visits at 4±1 weeks and at 12±2 weeks post last treatment (FU1 and FU2).
