The Beauty Prep -- and Products -- for a Sunny Day

Makeup
On the beach or by the pool, wear as little makeup as possible because, in bright sunlight, it becomes "quite visible" and you risk looking clownish, says Allure's Wells. For the lip gloss (with SPF) and waterproof mascara you might wear, choose soft, natural colors, she suggests. "It's not the time for opaque Parisian French lipstick ... and no shimmer on the face. It looks strange in the light of day."

However, once you're done in the sun for the day and your skin has a deeper tone -- whether it's natural or bottled -- it's time to punch up the color, advises makeup artist Ashunta Sheriff.

Sheriff, an adviser to Mary Kay Cosmetics, recently returned from a Caribbean vacation and made the shift from a light coral blush to a full-blown spice color, she says. She'll pack a similar color for clients Alicia Keys and Mary J. Blige on their summer travels.

"You should wear the same color family that you wear in the winter or spring, but now you should be getting deeper," she advises. For a woman with light skin who gravitates toward pinks and nudes for her lips and cheeks, try tawny or apricots, and those with olive skin who normally wears peach might consider coral. Orange-coral colors, raspberry, cinnamon and spicy brown all complement darker skin once they've had a hint of sun.

She does shy away from concealer, powder and foundation because a tan tends to even out skin discoloration, Sheriff explains.
