Biostimulators, or biostimulatory fillers, are injectables that work by triggering an inflammatory response in the body. That response leads to a boost in collagen production not seen with other dermal fillers.
Each filler’s ingredients vary, but they all work similarly. Sculptra Aesthetic is made of poly-L-lactic acid (PLLA), and Radiesse is made of calcium hydroxyapatite (CaHA), essentially ions of calcium and phosphate similar to what’s naturally occurring in our bones.
