"This includes walking to work, being inside your car, [or sitting in a room with a window]. UV-A rays, which cause both skin cancer and premature aging, can pass through glass windows," says Dr. Brian Ginsberg, a board-certified dermatologist and assistant professor at Mount Sinai Hospital. "Also, don't be fooled by a cloudy or snowy day. Clouds can let through up to 80 percent of the UV light, and snow reflects it, which actually increases your need for protection."
SPF should be applied anywhere that's exposed, including your face, chest, hands, ears, tops of your feet, and even your scalp. Sun Bum's Scalp & Hair Mist SPF 30, $14.99, has you covered — literally — on that last one!
