Description
Myristoyl Pentapeptide-17 is a specially engineered peptide for eyelash and eyebrow growth formulations. The myristoyl fatty acid modification significantly enhances its penetration through the hair follicle, ensuring efficient delivery to lash matrix cells where hair growth is regulated.
At the molecular level, this peptide upregulates keratin gene expression (KRT5, KRT14), stimulating the production of structural proteins that give lashes their strength, length, and pigmentation. Clinical trials show improvements in lash length (+25%), thickness (+18%), and darkness (+15%) after 6 weeks.
Compatible with both aqueous and ethanol-based delivery systems. Frequently combined with Biotinoyl Tripeptide-1 for enhanced dual-action eyelash serums. Recommended concentration: 2-5% in the final product.
COSPEP provides Myristoyl Pentapeptide-17 in bulk quantities with complete quality assurance documentation, including HPLC purity certificates, mass spectrometry confirmation, and stability data.
