Palmitoyl pentapeptide 4 is a bioactive peptide with anti-ageing effects, commonly used as a cosmetic ingredient. It acts as a signal peptide that promotes collagen synthesis by stimulating fibroblasts to produce collagen (types I, III, and IV), fibronectin, and glycosaminoglycans. This makes it a safe and effective anti-aging ingredient for skin improvement.
