Palmitoyl Tripeptide-5

Palmitoyl tripeptide-5 activates the TGF-β growth factor pathway — the skin’s master switch for collagen synthesis — mimicking the body’s natural wound-healing signal to kick dermal matrix production into higher gear. Manufacturer data show increased collagen synthesis and visibly reduced wrinkle volume at low ppm dosing. As a stable, gentle peptide it suits daily use in serums and eye creams and combines safely with other actives. Its TGF-β focus differentiates it from Matrixyl-type peptides, making multi-peptide products that include both mechanisms more compelling. Expect gradual firmness and smoothing over 8–12 weeks, not overnight transformation.
