The Effect of UV-Induced Gene Activation On Photo Skin Aging

The primary mechanism of UV-induced skin aging is mediated by the generation and accumulation of free radicals including reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS or free radicals not only can damage proteins, DNA, cellular membrane and … Continue reading

Enhanced Expression of Cylooxygenase-2(COX-2) In Chronological Skin Aging And Photoaging

Skin aging can be attributed to photoaging (extrinsic) and chronological (intrinsic) aging. Photoaging and intrinsic aging are induced by damage to human skin attributable to repeated exposure to ultraviolet (UV) irradiation and to the passage of time. COX-2 is a … Continue reading
