Sculptra® Aesthetic (injectable poly-L-lactic acid) is a biocompatible, biodegradable synthetic material which is gradually and naturally absorbed by the body that has been used by physicians for decades. It’s a facial injectable that works gradually in a series of treatments—on average, three injection sessions over a few months. It begins to work within the deep dermis, where your skin’s structure is reinforced as Sculptra Aesthetic helps to replace lost collagen. This reinforced collagen structure provides a foundation that gradually restores the look of fullness of your shallow to over time. Poly-L-lactic acid has been used for decades in dissolvable stitches and as a facial injectable since 1999 in over 30 countries.
