1. Layer Your Moisturizer
Sun, chlorine and saltwater can take a toll on skin, leaving your body dry and itchy. Instead of slathering on a heavy cream, which sounds as appealing as wearing a wool sweater to the beach, Airan suggests rehydrating in the shower (Olay's body wash contains vitamins E, B3 and B5 to help reduce water loss), then applying a lightweight lotion to damp skin.

"A dull complexion is the biggest complaint I hear after beach season," says Airan. Her solution: Wash with a mild soap and face-cleansing brush to remove dead skin, then dust on a light-reflecting powder throughout the day. "I keep an extra compact in my desk for when I need a boost," she says.

3. Spots Be Gone
Freckles, sun splotches -- as far as this porcelain-skinned derm is concerned, they both need attention. While prescription-strength bleaching creams help, these formulas also cause sun hypersensitivity, so wait until the fall to start using one. For stubborn spots, Airan uses the YAG laser (about $350 per spot) to zap away pigmentation.

4. Take Vitamins
"We're constantly telling our patients to minimize sun exposure," says Airan. "But UV rays actually trigger vitamin D synthesis, which studies have found to help prevent osteoporosis." If you aren't getting at least 10 minutes of direct sunlight three times a week, consider taking a daily supplement.
