Myristoyl Pentapeptide-4

Product Description

Myristoyl Pentapeptide-4 is a synthetic lipopeptide composed of a fatty acid (myristic acid) linked to a five-amino acid peptide chain (Lys-Thr-Thr-Lys-Ser). It functions as a signal peptide that stimulates the production of extracellular matrix components like collagen and fibronectin, improving skin firmness and elasticity. Additionally, it is known to support the growth of eyelashes, eyebrows, and scalp hair by encouraging keratin expression in hair follicles. It is commonly used in anti-aging skincare products, lash serums, and hair growth treatments due to its proven ability to condition skin and hair while maintaining excellent skin tolerance.
