Argireline- Summary
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.
- Argireline is the most widely researched topical 'Botox-alternative' cosmetic peptide, an acetylated hexapeptide that inhibits neuromuscular transmission to relax facial muscles and reduce dynamic wrinkle depth by 17–27% in clinical studies.
