Myristoyl pentapeptide-4 is a bioactive peptide used as a cosmetic ingredient to promote hair growth. This synthetic peptide, composed of Lys-Thr-Thr-Lys-Ser (KTTKS), targets keratin to activate gene transcription and translation, enhancing hair elasticity and strength. It also stimulates HaCaT cell proliferation, human hair follicle papilla cell migration, and skin fibroblasts to produce collagen and fibronectin, aiding in wrinkle reduction, improved skin elasticity, wound healing, and skin repair.
