SCULPTRA (PLLA) is a bio-stimulating treatment. Sculptra works by addressing the underlying cause of aging skin from loss of collagen. Once injected in the face (or buttocks), Sculptra stimulates the natural growth of new collagen. This leads to restoration of facial volume over time and a dramatic improvement of the skin texture. Results are natural and become noticeable after 2-4 sessions (based on individual concerns). The effects of Sculptra can last up to 25 months.
