Collagen Stimulators
Collagen stimulators such as poly-L-lactic acid and PDLLA are injectables that trigger the skin's own collagen production, gradually restoring volume and firmness over 2 to 3 months with results lasting up to two years.
Overview
They suit people wanting natural, gradual improvement rather than instant filler volume. Correct dilution and technique prevent nodules.
