Doris Day, MD, Dermatology, answeredUse sun protection every day and year round to reduce the signs of aging. Don’t forget your neck and chest. Use SPF 15 and up, and remember to reapply every two hours. And not just at the beach -- this is for anytime you plan to go outdoors. UVA (think of “A” for aging) goes through glass, so you need a sunscreen with both UVA and UVB protection -- even in your car.
