Sculptra is an injectable cosmetic filler that contains poly-L-lactic acid (PLLA), a biocompatible synthetic material. It’s primarily used to correct facial volume loss, particularly in areas like the cheeks, temples, and jawline, by stimulating the body’s natural collagen production. Unlike hyaluronic acid fillers, Sculptra provides gradual and long-lasting results, typically requiring multiple treatment sessions spaced several weeks apart to achieve optimal outcomes.
