cosmetic peptides
Cosmetic peptides are bioactive short-chain amino acids that deliver targeted skincare benefits through precise biological mechanisms. They are widely used in modern cosmetic and dermatological formulations for their anti-aging, brightening, moisturizing, and repairing effects.
These peptides act by stimulating collagen and elastin synthesis, scavenging free radicals, modulating neurotransmitter activity, and inhibiting melanin production. Typical examples include Argireline (anti-wrinkle hexapeptide), Copper Tripeptide (GHK-Cu) for skin regeneration, Palmitoyl Pentapeptide-4 (Matrixyl) for collagen renewal, Nonapeptide-1 for brightening, and L-Glutathione as a powerful antioxidant.
With high bioavailability and gentle efficacy, cosmetic peptides offer a science-driven approach to healthier, firmer, and more radiant skin, making them essential actives in next-generation skincare innovations.
