Poly-L-lactic acid (PLLA/Sculptra) differs from HA fillers in that it primarily works by:
-
A
Providing immediate volumization through water-binding hydrogel expansion
-
B
Stimulating the body's own collagen production over weeks to months as a biostimulator
-
C
Cross-linking with native tissue proteins to create permanent structural support
-
D
Blocking neural signals to the overlying musculature similar to neurotoxins
