This sounds like a no-brainer, but it's crucial – and something people too often don't do. "As soon as a sunburn becomes evident, get out of the sun," says Bowe. Some damage has already been done, and you don't want to harm your skin any more. That means moving the backyard beer session inside, calling it a day in the garden, or popping up the umbrella at your patio table. "Stay out of the sun until the burn fades," says Friedman.
