Myristoyl Pentapeptide-17 is a synthetic peptide composed of five amino acids (pentapeptide) with a myristoyl group attached. The myristoyl modification increases its lipophilicity, which improves skin penetration and stability in cosmetic formulations.
This peptide is primarily used in eyelash, eyebrow, and hair growth products. It works by stimulating keratin production and supporting the activity of hair follicle cells, promoting longer, stronger, and fuller lashes or brows. By enhancing the microenvironment of hair follicles, it helps reduce hair shedding and supports hair density and vitality.
