Sculptra is used to reduce the appearance of fine lines and wrinkles, restore lost facial volume, tighten the skin, contour the jawline, and improve skin glow. Sculptra is a unique injectable made of poly-L-lactic acid and is a collagen stimulator, meaning it helps your body produce its own natural collagen, the protein that gives your skin its youthful fullness and elasticity. It can be injected on its own or used with microneedling.
