What Is Myristoyl Pentapeptide-17?

Myristoyl Pentapeptide-17 is a five-amino-acid peptide modified with myristic acid, designed to stimulate keratin production in hair follicles. It is commonly used in lash and brow serums to promote thicker, healthier-looking hair.

By supporting keratin synthesis, this peptide helps strengthen the hair shaft while promoting the appearance of fuller, more defined lashes and brows.
