Matrixyl- Summary
- Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.
- Matrixyl is the most widely used collagen-stimulating cosmetic peptide. As a matrikine — a fragment of type I procollagen — it signals skin cells to synthesize new collagen, elastin, and fibronectin, reducing wrinkle depth and improving skin firmness and elasticity.
