Poly-L-Lactic acid injection (typically made from fermented sugar beet pulp) is biocompatible, biodegradable and used to stimulate your own restoration of collagen to help reduce overall facial volume loss.  
 
Most require a series of treatments the first typically using 2 vials followed by another 2 vials 2 months later.   If we lose 1-2% of our collagen every year over age 30, shouldn’t we fight to get some of that back?!
