It is a brand name for a dermal filler substance used in cosmetic injectables to repair wrinkles, creases, and loss of face volume. It is constructed of poly-L-lactic acid, a synthetic substance that is both biocompatible and biodegradable. Sculptra differs from other dermal fillers, such as hyaluronic acid fillers, in that it stimulates collagen formation in the skin rather than filling wrinkles or adding volume.
