Another reason to use lots of sunscreen
Sunday, September 17th, 2006 When sunscreen is applied, its UV filters reduce the amount of UV radiation that penetrates the skin. Over time however, the filters themselves penetrate below the surface of the outer layer of skin, leaving the body vulnerable to UV radiation.
In fact, when commonly used sunscreens (octylmethoxycinnamate, benzophenone-3 and octocrylene) are abasorbed, they actually generate reactive oxygen species (ROS) that cause oxidative damage. This leads to skin damage and increases in the visible signs of aging, according to researchers at the University of California, Riverside.
