FDA Announces Stricter Guidelines For Sun Screens

MIAMI, FL - JUNE 15: Doctor Antonella Tosti, Dermatologist University of Miami School of Medicine, displays an image on her iphone of a mark on the skin of Michael Casa Nova, 12, as she uses it as a dermatoscope while examinging him for symptoms of skin cancer due to sun exposure on June 15, 2011 in Miami, Florida. The federal Food and Drug Administration announced that sunscreen manufacturers are to change the labels on their products to prohibit the use of certain marketing terms. The new rules are meant to help clear up confusion about the meaning of "sun protection factor," or SPF, and other terms like "waterproof." (Photo by Joe Raedle/Getty Images)
