Mechanism of Action
Myristoyl Pentapeptide-17 stimulates dermal papilla cell proliferation and extends the anagen (growth) phase of the hair cycle by upregulating vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) expression. The peptide enhances blood microcirculation in the hair follicle bulb, delivering essential nutrients and oxygen for optimal keratinocyte proliferation.
