Sculptra is a poly-L-lactic acid implant that is biocompatible and biodegradable. Upon injection, this implant adds volume to areas that are concave or depressed, and is typically used to correct skin creases, wrinkles, folds, and other skin issues caused by the aging process. Sculptra can be used in large volume corrections, including those caused by lipoatrophy, or the loss of significant facial fat that is common in individuals suffering from HIV/AIDS. This is one of the longest lasting dermal filler available on the market, in part because the ingredients help the body create its own supply of collagen, rather than simply filling in areas with lost volume.
