1.MECHANISM OF ACTION

Palmitoyl Tripeptide-5 stimulates collagen synthesis by activating fibroblasts and upregulating the production of collagen types I and III. Its palmitoyl tail facilitates deep dermal delivery, where the peptide sequence binds to specific receptors involved in extracellular matrix remodeling. This action not only boosts collagen and elastin formation but also inhibits matrix metalloproteinases (MMPs) that break down these structural proteins, resulting in improved skin density, firmness, and resilience.
