Verdict

Palmitoyl Tripeptide-1 (Gly-His-Lys sequence; component of Matrixyl 3000) drives collagen and glycosaminoglycan synthesis via fibroblast stimulation. CIR Expert Panel confirms Tripeptide-1 and its fatty acyl derivatives safe as used in cosmetics. A 28-day clinical study on 32 volunteers showed significant reductions in wrinkle depth, volume, and number. Standalone formulations show retinoid-comparable activity without irritation. No EU or US regulatory restrictions.

US Note

CIR Expert Panel confirmed Tripeptide-1, Hexapeptide-12, their metal salts and fatty acyl derivatives, and Palmitoyl Tetrapeptide-7 are safe as used in cosmetics. Covered under CIR safety assessment for this ingredient class.
