It seems like every day a patient will ask a recommendation for a sunscreen. One realizes that one knows little about the safety of these products. The thrust of sunscreen promotion is the iconic SPF: Sun Protective Factor. This has gone from 15 to 30 to 50 to 80 and now to 100!! The reality is that a SPF of 15 or 30 is enough. What should concern you more is the safety of these products. GoodGuide is reputable organization whose goal is to "provide the world's largest and most reliable source of information
