When injected into specific areas, biostimulators like Sculptra and Radiesse work beneath the surface of the skin to activate fibroblasts, the cells responsible for collagen production. Over time, this process restores lost volume and reduces the appearance of wrinkles, with results that can last for up to two years. As collagen regenerates, it not only lifts and fills the skin but also improves its texture and elasticity. The result is a smoother, firmer, and more youthful complexion that looks completely natural.
