• Slather up. "Rain or shine, apply sunscreen every day," advises Downie. "My darker-skinned patients think they're automatically protected, and they're not. They need to apply an SPF of at least 30 in the morning and then again throughout the day."

• Don't rely on tinted moisturizers. "Remember that foundations and tinted moisturizers with SPF are makeup," Downie explains. "Meaning that you apply it heavier to some areas and lighter to others." For full sun protection, use a mattifying, oil-free sunscreen underneath any face makeup.

• See your dermatologist annually. "Just don't be burned when you come! In order to best analyze your skin, doctors need to see your skin as close as possible to its natural tone," explains Downie. "This will allow her to get a better look at any abnormalities."

• Spray your feet! And your ears, nose, back, shoulders, and knees. "People get accidentally burned in these places most often, because this is where the sun is hitting them when they go outside for lunch," says Downie. Keep a spray sun block at your desk and apply it to these spots 30 minutes before escaping your cubicle for lunch.

• And keep sunblock in the car. "The biggest hurdle to applying sunblock regularly is overcoming behavioral barriers," adds Downie. "Keep face and body block in your car so that you have it handy whenever you feel the need for application. Over time you'll just get accustomed to reapplying frequently."

• Don't rationalize tanning with a need for Vitamin D. "Vitamin D deficiencies have been a hot topic in the dermatology world," she explains. "And some people think that if they're deficient, they have license to sit in the sun, but one person dies from melanoma every 62 minutes. You should be able to get the Vitamin D daily intake you need from oral supplements and eating well."
