Sculptra is not a hyaluronic acid filler; it is a powerful biostimulator. Its active ingredient is poly-L-lactic acid (PLLA), a biocompatible substance that acts as a 'seed' for new collagen growth.
When injected, Sculptra kickstarts your body's natural collagen production mechanism. Over the following weeks and months, your skin gradually builds its own new collagen around the PLLA microparticles. This process restores volume and structure from within, creating a remarkably natural and long-lasting result. It doesn't just fill wrinkles; it addresses the underlying cause of facial aging.
