Collagen production in the body decreases as you get older and/or are exposed to the sun. Wrinkles are on of the first visible signs of this. Sculptra is injected into the deep layer of the skin where collagen naturally exists and is made. Sculptra works by initially filling a wrinkle with small PLLA (Poly-L-lactic Acid) beads. As the beads biodegrade the body may produce new collagen where Sculptra is injected. Sculptra will provide gradual, longer-lasting results with minimal downtime.
