Palmitoyl tripeptide-1 is a lipophilic peptide that signals through TGF-beta pathways to promote collagen and extracellular-matrix synthesis in skin-cell cultures, making it a core active in anti-aging formulation research. Its palmitoyl anchor improves membrane penetration in topical studies. This product is a white lyophilized powder at >=99% HPLC purity in a sealed vial. Lot documentation and flexible pack sizes are available for cosmetic R&D teams. Reconstitution with sterile water or bacteriostatic water is straightforward, and the resulting solution should be used promptly or stored according to your protocol.
