Palmitoyl tripeptide-1 is a peptide that has shown the ability to stimulate collagen synthesis in a human fibroblast culture and prevent its degradation after the exposure to UVA light. It promotes the production of elastin, hyaluronic acid, glycosaminoglycan, and fibronectin with a visible reduction of wrinkles in terms of length, depth, and roughness. Comparable to retinoic acid with regards to its activity, it does not trigger irritation. Collagen and glycosaminoglycan synthesis are stimulated, the epidermis is reinforced, and wrinkles are diminished.
