Carry sunscreen everywhere you go, and reapply it often
While many Americans have jumped on the sunscreen bandwagon, it's important to review the steps for truly protecting your skin. There's more to it than squeezing a dollop of sunscreen out of the tube and rubbing it on your face before going out to play nine holes of golf or watch a ball game.
The Skin Cancer Foundation recommends applying sunscreen liberally to all exposed skin 30 minutes before going outside—so it has time to soak in—and reapply every two hours or immediately after swimming or excessive sweating.
