There’s no doubt that ultraviolet (UV) radiation from the sun is a primary contributor to skin aging as well as other skin conditions, but researchers are now starting to question the effects of our digital devices. High energy visible (HEV) blue light from personal electronics has become a hot topic in medical research with some arguments that it may prevent and treat some skin diseases while others find it can increase DNA damage and cell and tissue death. So which one is it? Preliminary studies find concerning results, but the data is far from conclusive. However, the research literature seems to indicate that blue light from sun exposure, even on a cloudy day, is more significant than exposure through digital use. If you’re looking to maintain healthy skin, the most important first step is to apply sunscreen daily. For glowing youthful skin, shop our large variety of medical-grade products at Dr. J. J.
