Sculptra fillers, also known as poly-L-lactic acid (PLLA) fillers, are injectable treatments designed to stimulate collagen production in the skin. Unlike traditional fillers, Sculptra works gradually over time, offering subtle yet long-lasting results. Sculptra fillers work by stimulating the body's natural collagen production process. The biocompatible PLLA microparticles within the filler solution prompt the skin to produce new collagen, resulting in improved volume and elasticity.
