poly-L-lactic acid

Poly-L-lactic acid (PLLA) is a biodegradable, synthetic material derived from lactic acid, a natural compound produced by the body during metabolism. Widely used in medical and cosmetic procedures, PLLA is injected into the skin to stimulate collagen production, which helps improve volume and reduce wrinkles over time. Its effects gradually develop as the body absorbs the material and creates new collagen, resulting in a natural-looking enhancement. PLLA is biocompatible and resorbable, meaning it safely breaks down in the body without leaving permanent traces, making it a popular choice for facial rejuvenation treatments.
