Hello, Sculptra actually does stimulate collagen in the face and results are seen typically after 6 treatment sessions spaced one month apart. The majority of my patients see very consistent fantastic results. I would definitely recommend that you seek the assistance of a board certified dermatologist that has plenty of experience with Sculptra. This treatment should not be done by just anyone. Good luck, Dr. Downie.
Yes, Sculptra does replace lost collagen and I have seen it work up to the 2 year indication. Gradual results overtime creates a natural appearance.
