3 Reasons to Wear Sunscreen While Driving
Windshields block UVB but not UVA The glass in your windshield stops most UVB rays, but UVA rays—which cause aging and skin cancer—pass through easily.
Side and rear windows offer even less protection These windows are usually not treated to block UVA, so your arm and the side of your face get exposed during commutes or errands.
The damage adds up silently over years You won’t notice the radiation until a dermatologist does. A daily moisturizer with SPF 30 or higher takes ten seconds to apply before you leave.
