Palmitoyl Tripeptide-5

INCI: PALMITOYL TRIPEPTIDE-5

CAS Number
None
Function
Signal peptide (Syn-Coll, DSM/Pentapharm/Symrise) that mimics TGF-β (transforming growth factor-beta), stimulating collagen synthesis in fibroblasts via the TGF-β signaling pathway. Palmitoyl lipidation enhances stratum corneum penetration. Used in supramolecular collagen nanoparticle formulations combining lactoferrin, recombinant human collagen, and this peptide.
