Brief summary
Evaluation of treatment on the upper arm with Sculptra and Sofwave on the same day versus Sofwave followed by Sculptra 1 month later.
Detailed description
This is a prospective, single site, split-body, intra-individual comparison pilot study. Each subject serves as their own control. 13 subjects will be recruited for a goal of treatment 10 subjects. One upper extremity (proximal medial arm) will be randomized to receive immediate combination therapy with both injectable poly-L-lactic acid (PLLA, Sculptra®) and synchronous ultrasound parallel beam technology (Sofwave™) administered over the same day. The contralateral arm will undergo sequential therapy, with PLLA administered at baseline and synchronous ultrasound parallel beam treatment one month later (Treatment Visit #2, Day 30). The study employs a randomized, split-body design to minimize inter-patient variability, with blinded investigator assessment of efficacy outcomes through assessment of standardized digital photographs and video of snap test (skin turgor test). taken during the Final Visit (Day 120).
