Myristoyl Pentapeptide‑17 – The Safe, Peptide‑Based Solution for Naturally Longer, Thicker Eyelashes
A biomimetic pentapeptide that activates keratin‑5 gene expression (up to 160%), stimulates lash follicle growth, and delivers clinically proven results – 59% increase in lash density in 6 weeks. Gentle, non‑irritating, no damage to hair follicles.
Product Overview:
Myristoyl Pentapeptide‑17 is a synthetic peptide specifically designed to promote eyelash growth. It works by targeting keratin‑5 gene expression, which is essential for the production of keratin – the key structural protein of hair. Each eyelash follicle goes through three phases: anagen (growth), catagen (transition), and telogen (resting). With age, most follicles remain in telogen, and lashes become shorter, thinner, and sparser. Myristoyl Pentapeptide‑17 reactivates dormant follicles by upregulating keratin gene expression by up to 160%, stimulating the production of keratin‑5 and promoting the anagen phase, resulting in visibly longer, thicker, and darker lashes.
