It may sound a little extreme (and even more unglamorous), but if you're hanging out in the sun all day, sun-protective clothing is a must. "Regular clothing gives very little sun protection," Graf says. "A white shirt will give you [SPF] three to five, while darker colors still only give you [SPF] eight to nine."

Before you roll your eyes at sun-protective clothing, check out brands like Mott 50 and Parasol (which is carried at Neiman Marcus). The fabric has an Ultraviolet Protection Factor (UPF) rating of 50, and they make dresses, tees, pants and skirts.

Make like your favorite Old Hollywood actresses and don oversize sunnies and a wide-brimmed hat while outdoors. Or grab a parasol to shield yourself from UVA/UVB rays. (Yes, we really are trying to bring back the parasol.) Believe it or not, the eye is a common spot for skin cancer, and shades can help. Hats are great for protecting your face, and there are lines -- like Solartex -- with extra-high SPF.

Not ready to rock a hat? New York City dermatologist Gervaise Gerstner M.D. says, "Don't forget SPF on the scalp and part line!" While pulling the hair back to cover up your part helps, it's still important to spray sunscreen over the hair, as the scalp is one of the most common areas people overlook when applying sunscreen.

Sure, you may reach for a pair of sunglasses when you get in the car, but you may not realize just how much sun exposure you get while driving. While glass blocks UVB rays, and your windshield is designed to block UVA rays, your car's side windows let in about 63 percent of UVA rays, according to Graf.

Because UVA rays are longer and travel deeper into the skin (making them responsible for wrinkles and other signs of aging), it's important to wear sunscreen when driving -- yes, even in winter -- or apply clear, UV-protective film to your car windows.

Eating healthy is not only good for your waist line -- it also helps protect your skin from sun damage. Antioxidants like beta-carotene (found in carrots, sweet potatoes and spinach), catechin (found in green tea, dark chocolate, berries and apples), lycopene (found in tomatoes, watermelon and pink grapefruit) and sulforaphane (found in broccoli, kale and brussel sprouts) help your skin prevent, and repair itself from, sun damage.

Sunscreen in a pill? Well, sort of. You can sneak in more sun-shielding antioxidants by taking a dietary supplement like Heliocare, $16.99. Dermatologist Vivian Bucay, M.D., calls it "a multifaceted approach to protecting yourself from the sun." Heliocare contains Polypodium leucotomos, a fern native to South America that has been used for centuries to treat skin conditions like sunburn, eczema and psoriasis. "Take it in the morning, and then if you're going to be outside, take it again a few hours later," says Bucay. Just remember that it's a good complement to wearing sunscreen, not a substitute for it.
