healthNew Rules for SunscreensIf you use sunscreens, be sure to reapply them frequently. Many sunscreens contain the filters octylmethoxycinnamate, benzophenone-3 or octocrylene, which reflect ultra violet rays away from your skin to protect it only when they are on the surface of the skin. However, when these sunscreens are absorbed and the skin is not re-coated, they increase skin production of harmful oxidants that can cause skin aging and cancer (Free Radical Biology & Medicine, September 2009). Reapplying the sun screen so some remains on the skin's surface can prevent this damage.
A comprehensive review of more than 1,000 sunscreens was conducted by the Environmental Working Group in summer of 2009. Their findings, with brand name listings and recommendations, are available here.
