It didn't take a trip to Tahiti to discover some troubling facts about your favorite sun tan lotions. According to Consumer Reports, nearly one third of sunscreens tested failed to deliver the SPF protection promised on the label.
The group examined 34 popular lotions and sprays in the study - applying them to the backs of test subjects and exposed them to ultra-violet light. Of the products tested, 11 quote "missed the mark" according to the report by anywhere from 16 to 70 percent.
"It was water protection. They took people who had them lathered with it and they put them in tubs of water for 40 or 80 minutes and checked them again when they got out of the tub to see if it was still on because after all, when you're on the beach, you're gonna go in the water," said Dr. Marc Siegel. "They found that up to a third of them it washed off. What good is that?"
Some of the worst offenders on the list include: Vanicream SPF 50 plus, Yes to cucumbers Natural SPF 30 and Aloe Gator SPF 40 plus.
Sun tan lotions with the best rating: La Roch Melt-in-Sunscreen Milk 60, Coppertone Water Babies SPF 50 and L'Oreal Quick Dry Sheer Finish 50 plus.
An F-rating doesn't mean the lotions aren't protective however, it simply means - according to the report - that you may not be getting the protection you think you are.
