Skimp on Sunscreen
"Your sunscreen probably isn't shielding you from sun damage because most of us don't apply the shot-glass-sized amount (1 ounce) of SPF 30 or higher sunscreen -- the minimum experts say we need to protect us.'Most people under-apply by one-fourth. Whatever you're putting on is probably too little, so at least double it,' says Jeffrey Dover, MD, FRCPC, associate clinical professor of dermatology at Yale University School of Medicine] and director of SkinCare Physicians in Chestnut Hill, Mass. Also, many people also don't apply sunscreen every two hours as dermatologists recommend."
