Skin Care Tips from A to Z

Skin cancer is the second-most common cancer in women ages 20 to 29. One in five Americans will develop it in their lifetime. That means you're more likely to get this deadly disease than to get hit by a car, marry a millionaire, write a best seller-or have sex this week.

Covering your face with a towel isn't enough. From the neck down, UV exposure makes skin leathery and cellulite more dimpled. Here, the breakthroughs in safe sunning from head to toe.

While both are bad for the skin, a tan is actually worse than a sunburn, according to Hirsch. "A burn is inflammation—your body's way of healing itself after injury," she explains. "But a tan means your skin is giving up—it's not even trying to fight off the damage anymore."

With all the new lightweight, easy-to-apply formulas available, there's no excuse for not wearing sunscreen. But if you've been lazy about reapplying and start seeing red, the best treatment is to take an aspirin (this fever-reducer lowers skin inflammation, too) and slather on a topical antioxidant like coffeeberry or vitamin C. Lupo calls the Revalé coffeeberry-based line "the morning-after remedy for sun damage." The silver lining to your pain? You're probably not going back out to bake anytime soon.
