The skin is frequently subjected to a variety of environmental trauma and stress. It is unavoidably subjected to blue light due to the increased use of electronic equipment, including indoor lighting and digital gadgets like smartphones and laptops, which have a range of detrimental effects. Numerous studies have shown that being exposed to blue light accelerates the ageing process and produces cutaneous hyperpigmentation. At times, skin protection may be crucial for protection against blue light. Human skin exposed to blue light may produce free radicals as a result of the decline in carotenoids. It is thought that this oxidative stress on melanogenic precursors causes pigmentation alterations, such as sudden and persistent darkening of the skin. According to research, the creation of superoxide by blue light may play a substantial role in the aging and carcinogenesis of the skin. Overexposure to ROS (Reactive Oxygen Species – Free Radicals can harm skin cells, accelerate aging, cause hyperpigmentation, and cause melisma. By generating DNA damage, these unstable chemicals also cause inflammation and the destruction of the skin’s healthy collagen and elastin, which furthers skin laxity, early aging of the skin, and wrinkles.J Cosmet Dermatol.
