Sculptra is an injectable collagen treatment that uses a substance called poly-L-lactic acid, PLLA. Sculptra contains microparticles of PLLA that are injected into the deeper skin layers . The microparticles are mixed with sterile water before injecting, so the injected volume will have an initial effect that will fill out wrinkles and add volume to the skin. A few days after the injection, the water and other constituents are absorbed by the body while the PLLA microparticles remain in place. Now you will look like you did before the treatment, but deep inside the skin, collagen production will increase. Slowly but surely, Sculptra starts rebuilding collagen. Sculptra provides proven volume. On average 3-4 treatments are needed.
