Sculptra is a facial injectable made from poly-L-lactic acid, which helps to replace lost collagen. Collagen is a key structural component that keeps skin looking youthful and smooth. As you age, your body’s collagen production decreases, and you may begin to see wrinkles. Sculptra works to correct shallow to deep facial wrinkles and folds by replacing lost collagen, which can help provide a refined, youthful looking appearance. On average, three injection sessions are needed over a period of a few months. The number of injection sessions and the number of injections per session varies from person to person. A full treatment of Sculptra can last more than two years.
