Sculptra is an injectable poly-L-lactic acid (PLLA) that works gradually, over time, to help stimulate the body’s own, natural collagen production.

Poly-L-lactic acid is one of the most well-researched polymers used for applications both in cosmetics and medical device applications. A synthetic compound, it is derived from renewable plant sources, such as sugar cane, cassava root and corn starch, and is one of the components of dissolvable stitches. These natural sources are why, although it is considered a “plastic,” it is also bioactive (capable of having an effect or interaction with living tissue) and biodegradable (capable of being broken down or decomposed by living things, such as microorganisms).

Sculptra is not injected just under the skin to give it fullness. Rather, it is injected in the deep dermis layer of skin, where it can work to restore the skin’s underlying structure.
