Collagen inducers
Collagen stimulators are injectable active ingredients (e.g., PLLA, PCL, CaHA) that boost the body's natural collagen synthesis. Instead of providing immediate volume, these formulations naturally stimulate fibroblasts, resulting in gradual, long-lasting skin-tightening and rejuvenating effects. The results develop over 6–8 weeks and can last up to 12–24 months. They are particularly suitable for treating deep wrinkles, volume loss, and contour deficiencies, especially in the midface, temples, jawline, and neck areas. It is important to note that their application requires medical expertise and precise protocols.
