Efficacy and Safety of Poly-L-lactic Acid (Sculptra)

A Prospective, Randomized, Multicenter, Self-controlled, Blinded Trial on the Efficacy and Safety of Poly-L-lactic Acid - SCULPTRA - for the Treatment of Corporal Skin Flaccidity.

This study aims to assess efficacy and safety of Sculptra in the treatment of skin flaccidity in selected areas - arms, anteromedial region, and gluteal regions. To assess the efficacy of Sculptra®, via adapted Global Aesthetic Improvement Scale -GAIS- score determined by blind evaluator, in the treatment of skin flaccidity on the anteromedial region of arm and gluteal region, 4 months after initiating the treatment, based on the assessment of the corporal side randomized to be the first to receive treatment . Considering as an alternative hypothesis of interest a 70% value of the subjects the treated side would have higher GAIS than the untreated side.
