NICOTINOYL SH-PENTAPEPTIDE-19.

This innovative ingredient functions as a potent signaling peptide, initiating the skin's intrinsic repair mechanisms. It is designed to stimulate the regeneration of mature skin, enhancing its structure and visibly diminishing the appearance of fine lines and wrinkles. The ingredient also contributes to a refined skin complexion and improved elasticity. Leveraging its nicotinoyl component, it is understood to upregulate collagen production in fibroblast cultures, mitigate elevated dermal glycosaminoglycans often associated with photodamage, and augment the synthesis of crucial epidermal proteins such as keratin, filaggrin, and involucrin. Furthermore, it exerts anti-glycation effects, counteracting skin sallowness, while simultaneously boosting cellular energy and impeding cellular senescence.
