Common Name(s): Myr-penta-17,lash growth peptide
CAS Number: N/a
DESCRIPTION
What It Does: Stimulates keratin synthesis in follicle keratinocytes for enhanced eyelash and eyebrow growth and density.
Why It's Used: Used in lash serums and brow treatments for keratin gene-mediated hair fiber thickening and growth stimulation.
How It Works: Myristoyl lipid tail delivers pentapeptide to follicle keratinocytes. activates keratin gene expression (particularly keratin 6 and keratin 16) and growth factors promoting follicle activity.
Typically Found In: Eyelash serums,brow treatments,hair growth products
