Solution: Covering Up

To find the best color for your skin, test the foundation on your cheek, close to the jawline. “This area will give you the truest match,” says New York City–based makeup artist Tanya Rae. When in doubt about the best shade, choose one that’s slightly darker—rather than lighter—than your complexion, so it warms your skin; going too light can make you look ashen. Blend with a damp sponge (or a brush) so the foundation lines disappear into the skin, says Rae, who likes Lancôme’s Teint Miracle (from $39, lancome-usa.com).
