Revolutionary Developments in Sun Protection

Today’s sunscreens are only effective in blocking ultraviolet light, not infrared or visible light. In recent German studies, it was shown that 50% of free radicals produced in the skin when exposed to sun are created in the visible and infrared ranges. The implication is that even the best sunscreens may provide inadequate protection from the sun. These extraordinary findings were presented by Dr. Jurgen Lademann at the Cosmetics & Toiletries Scientific Summit in June. This may help to explain why skin cancer rates continue to increase in most developed countries in spite of widespread use of high-quality sunscreens. As a result, our future approach to sun care may include new formulation strategies to absorb other parts of light and to be much more effective in neutralizing free radicals. Ultimately, this may mandate changes in our lifestyle to further restrict sun exposure.
