Sculptra is an injectable cosmetic filler. Sculptra is used to restore facial volume lost due to aging or illness. It is a collagen stimulator, not a facial filler, utilized to strengthen and tighten the skin. Sculptra contains poly-L-lactic acid (PLLA), which is a biocompatible synthetic substance that stimulates collagen production. Sculptra can be used to treat deep lines, creases, and folds to give you a more youthful appearance. Sculptra is injected deep into the dermis and gradually improves the affected area. The Sculptra process takes several weeks. You gradually begin to look younger, not all at once.
