PENTAPEPTIDE-17.

Operating at a molecular level, Myristoyl Pentapeptide-17 is paramount for promoting strong hair and lash development through the potent activation of keratin genes, which are fundamental for structural hair proteins. On the skin, it stimulates cell regeneration and markedly increases the synthesis of collagen types I, III, and IV, leading to a visibly smoother texture, improved elasticity, and enhanced firmness. It fortifies the extracellular matrix by boosting glycosaminoglycan production, actively contributing to the reduction of visible wrinkles. This peptide also exhibits anti-inflammatory effects by reducing pro-inflammatory cytokines, thereby calming and soothing irritated skin. Furthermore, it provides a biological defense, demonstrating efficacy against common skin microbes such as C. acnes and various fungi, while acting as an antioxidant to shield skin from environmental damage. It also plays a role in enhancing skin hydration and evening out tone by lightening age spots and reducing fine lines.
