Myristoyl pentapeptide-4 is a bioactive peptide known for its hair growth promotion effects and is used as a cosmetic ingredient. This synthetic peptide (KTTKS) targets keratin, activating keratin gene transcription and translation to improve hair elasticity and strength. It also promotes the proliferation of HaCaT cells, stimulates the migration of human hair follicle papilla cells (HDPCs), and encourages skin fibroblasts to produce collagen and fibronectin, which can reduce wrinkles, improve skin elasticity, and aid in wound healing and skin repair.
