Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens
Advanced Healthcare Materials, EarlyView.High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.
