28 { summer 2019 } h o u s e c a l l s Sunscreen 101 Let's shine a light on this all-important sun protectant WHO needs sunscreen? Everyone! Though it's best to keep babies under 6 months old out of direct sunlight using shade and protective clothing, the American Academy of Pediatrics recommends using sunscreen with an SPF of at least 30 on exposed areas such as the face and hands. WHAT kind? In all cases, choose a broad-spectrum sunscreen— products that combine several ingredients to prevent ultraviolet A and B rays from reaching the skin. For extended outdoor use, a stronger, water-resistant sunscreen will adhere better; for everyday use, an SPF-rated moisturizer may be more suitable. Chemical sunscreens have mimicked hormones in lab studies, may cause skin allergies, and could contain the environmental contaminants oxybenzone and octinoxate, so Dr. Rahbar recommends mineral (zinc- or titanium-based) sunscreens. Also take note of a sunscreen's expiration date as it loses effectiveness once expired. WHEN do we need it? Apply sunscreen 30 minutes prior to sun exposure to allow the product to bind to the skin. Sunscreens are ranked with a Sun Protection Factor, or SPF, that measures their ability to prevent UVB damage to the skin. (If unprotected skin reddens in 20 minutes, SPF 15 sunscreen theoretically stops burning 15 times longer, so roughly five hours.) Regardless of strength, however, the Skin Cancer Foundation advises slathering on more sunscreen every two hours, especially if you've been swimming, sweating, or toweling off. WHERE should it be used? Apply it to any part of the body that isn't covered by protective clothing. Don't forget the edges of ears, tops of feet, backs of hands, any exposed scalp (think hair part), and decollage. The Skin Cancer Foundation recommends applying one ounce—roughly a shot glass worth—of sunscreen to the body and a half teaspoon (a dollop about the size of a lima bean) to the face and neck alone. WHY wear sunscreen daily? Our skin absorbs plenty of ultraviolet radiation as we go about our everyday activities, though this incidental exposure may not cause us to burn. Even without reddened skin, which is a reaction to UVB rays, plenty of damage can be done by UVA rays—even on cloudy days.
