LUBBOCK, TX (KCBD) – A new report on something we should all use all year. After studying more than 500 beach and sport sunscreens the environmental working group says fewer than 10% made the grade. The main problem was those big SPF numbers showing mega-protection, not because they don't work, but because they give a false sense of security. Researchers decided the big numbers sound so good that people don't re-apply them as often as they should.
Instead, they assume the high sun protection factor lasts longer than it really does. The group adds that vitamin A, added to some sunscreens to slow skin aging may instead accelerate skin damage and increase the risk for cancer when exposed to sunlight, but the theory has only been tested in mice.
