I recently read an article on Sculptra that said it was made from poly L lactic acid and not hyaluronic acid. What is that, and how does it differ from ingredients in other injectable fillers?
Poly-L lactic acid is a completely different molecule from hyaluronic acid. It is a molecule that has been used to manufacture an absorbable suture for many years. Sculptra is a powder made up of the same molecule. When it is injected under the skin it causes the body to form collagen around the molecules therefore building up volume and skin thickness. It takes some time for the filler to cause this result and it requires 2-3 injections to achieve this.
