Matrixyl (Palmitoyl Pentapeptide-4)

Lipid-linked pentapeptide that signals fibroblasts to produce collagen, elastin, and hyaluronic acid. Widely studied in cosmetic dermatology as a collagen-stimulating topical. Matrikine peptide class.

Mechanism of Action

Pal-KTTKS sequence signals fibroblast matrix metalloprotease pathways. Acts as a matrikine — a collagen fragment that signals for collagen repair/synthesis (feedback mechanism). Upregulates pro-collagen I, fibronectin, and elastin production. Anti-wrinkle via structural dermis remodeling.
