TACTICS: "Slough off any dead, dry skin with a gentle daily scrub -- or monthly microdermabrasion treatments -- to enable foundation to go on smoothly," says Shaw. "Avoid tinted moisturizers," says celebrity makeup artist Napoleon Perdis. "They can obscure the natural glow of pretty, normal skin, leaving it looking dull and oily. If you're trying to enhance your complexion, a regular moisturizer, concealer, and shimmery bronzer is all you need." Perdis recommends spreading on a hydrating primer after applying moisturizer (and before foundation) to plump up the skin and fill in fine lines. "Drier skin can benefit from a foundation brush when applying makeup," says Quinn. "Using your fingers can cause streakiness -- especially on sensitive skin."

"Apply only the thinnest layer of foundation on your forehead -- or none at all," says Perdis. "Chances are you have fine lines and dry patches there, and makeup may exaggerate them."
