Palmitoyl Tripeptide-1 for Collagen Stimulation & Wrinkle Reduction — Skin & Hair
Signal peptide that stimulates collagen production and is a key component of Matrixyl 3000.
Overview
Palmitoyl Tripeptide-1 (previously known as Pal-GHK) is a signal peptide and one of the two active components in Matrixyl 3000. It stimulates collagen synthesis by mimicking the peptide sequence released during collagen breakdown. When combined with Palmitoyl Tetrapeptide-7, it creates a synergistic effect that both stimulates collagen production and reduces inflammation. Clinical studies show significant improvements in wrinkle depth, skin firmness, and overall skin quality. The palmitoyl attachment enhances skin penetration.
Indications
