What is Myristoyl Pentapeptide-17?

Myristoyl Pentapeptide-17 is a lab-engineered cosmetic ingredient formed by linking a myristic acid chain to a sequence of five amino acids, known as pentapeptide-17. This modification improves its ability to penetrate skin and hair follicles. Primarily used in hair conditioning products and lash serums, it functions as a signaling agent that interacts with cellular pathways in follicles, potentially influencing the hair cycle's active phase. In formulations, it appears in lightweight serums or conditioners, where the lipopeptide structure aids targeted delivery to promote visible improvements in hair density and length over time. Derived from amino acids, it offers a gentle alternative in cosmetic routines focused on hair health.
