(GLY14)-HUMANIN is a synthetic peptide analog derived from the natural humanin sequence, specifically engineered with a glycine substitution at position 14 to enhance its stability and bioactivity. As a multifunctional cosmetic ingredient, it exhibits potent cytoprotective and anti-aging properties by inhibiting oxidative stress and preventing cellular apoptosis in skin tissues. (GLY14)-HUMANIN promotes mitochondrial function and supports extracellular matrix integrity, effectively reducing the appearance of fine lines and improving skin resilience. Its optimized molecular structure ensures superior skin penetration and long-lasting efficacy, making it an ideal component in premium anti-aging serums, revitalizing creams, and daily repair formulations.
