Abstract

Skin photoaging, clinically characterized by wrinkles and hyperpigmentation, accounts for 80% of extrinsic aging. Chronic UV exposure drives this process via oxidative damage. However, its synergistic axis with mitochondrial dysfunction remains mechanistically elusive. This study aims to elucidate the mechanistic link between mitochondrial oxidative stress and UV-induced photoaging, focusing on reactive oxygen species overproduction as a central driver of cellular decline.
