A sunburn can sneak up on you, especially with hours spent running, biking, or swimming in the sun. A pocket-sized sunscreen is just what you need for quick reapplication.
This formula has a lot going for it, says Melanie Palm, M.D, a dermatologist at Art of Skin in San Diego, California and clinical professor at Scripps Encinitas Memorial Hospital. It offers great broad-spectrum coverage against UVA and UVB as well as high energy visible light, she adds. And at $6 a pop, you can afford to stash one in every pocket and bag you own. (After all, you should be wearing sunscreen all day, every day—even if you’re stuck indoors.)
