Health Watch -- Younger Skin: Sunblock
Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.
This week on Health Watch, we're talking about how you can keep your skin looking younger without paying a lot of money for fancy skin-care products. Dr. Sarah Weitzul, an expert on cosmetic dermatology at UT Southwestern Medical Center at Dallas, says the first and most important skin-care product you should buy is sunscreen.
Not only does sun exposure increase your risk for skin cancer, it's also the primary cause of wrinkles and other signs of aging. Look for a sunscreen that blocks both UVA and UVB radiation, and wear it every day, not just when you'll be at the beach or swimming pool. You get most of your sun exposure through daily activities like walking from your car to the office building or shopping center. If you're going to be in the sun for longer periods or if you're swimming or sweating, reapply the sunscreen regularly.
