Sculptra is an injectable poly-L-lactic acid that is injected under the skin. This stimulates the production of new collagen, which leads to more volume. Sunken areas of the face appear young and fresh again, while the elasticity and density of the tissue and the firmness of the skin improve at the same time, resulting in two to four years, sometimes even longer. Then the result slowly regresses - depending on the influences of genes, the environment and lifestyle. Even if the effect slowly disappears over the years, up to 50% of the result usually remains forever.
