MIAMI, FL - JUNE 15: Doctor Jonette Keri, Dermatologist University of Miami School of Medicine, displays the underside of Amy Rey's arm in contrast to the top side to compare what the sun has done to the top side as she examines her 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) less
