Sculptra® contains a special synthetic material known as poly L lactic acid, or PLLA. For more than 10 years, the medical community has relied on PLLA-based dissolvable sutures to help support the healing process after surgery. Based on the proven effects of PLLA, Sculptra® was developed to provide a unique treatment that corrects problems that are caused by fat loss under the skin, including sagging, drooping, hollow areas under the eyes, and a “too thin” appearance. Replenishing the skin’s volume also affects the way light falls on the face, giving a more youthful and beautiful appearance.
