The method of screening antioxidants for protecting the skin from UV radiation includes using the Briggs-Rauscher Oxidant Method (BROM) method to one or more antioxidants for predicting protection to the epidermal layer. One advantageous antioxidant formulation for use in sun screens, lip balms and other types of topically applied skin care products for protecting the skin from UV radiation includes a mixture of antioxidants in the skin care product including an effective amount of arbutin in combination with BHT, wherein the ratio of arbutin to BHT in the skin care product ranges from 1:4 to 4:1, and wherein the measured BROM value of the antioxidant mixture is greater than the sum of the BROM values of the individual antioxidants in the mixture at the same concentration. The measured BROM value of the resultant product is greater than or equal to 0.2 sec/μg. The antioxidant formulation may also optionally include hydroquinone, resveratrol, uric acid and/or atorvastatin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"UV protective skin treatment compositions and screening methods","description":"Provided are methods of screening antioxidants for skin protective capacity and antioxidant formulations which protect the skin from UV radiation.
