The FDA is coming out with clearer, more concise labeling for sunscreen this fall. Labels now show an SPF which tells you how long the sunscreen will protect you from UVB rays. UVA rays, which usually affect the skin on a deeper level and are a cause of skin cancer, have no existing test that can measure the level of protection as of yet. In order not to mislead the consumer, the new labeling will show a four star rating that reflects the level of UVA protection (low, medium, high and highest). This system would work together with the current SPF rating.
Remember, The Skin Cancer Foundation recommends using a sunscreen of 15 SPF or more with a combination of the following ingredients: stabilized avobenzone, ecamsule, oxybenzone, titanium dioxide and zinc oxide.
