The plump, rounded facial contours associated with youth are largely due to a thick layer of collagen that lies directly beneath your skin. As the years go by, much of that collagen is lost. That lost volume allows your skin to pool and sag into lines, wrinkles, and folds. Restoring lost facial volume is one of the most powerful anti-aging treatments, and is the primary focus of a wide range of dermal filler formulations. Dermal fillers, however, work by delivering a gel-like formulation into your facial tissues, plumping your skin and smoothing wrinkles and folds. Sculptra takes a different approach to improve facial volume and tone.
