Laura says blush can add life to older, sallow skin and brighten anyone's face. A key to getting it right is the color. "Blush colors should be natural," says Laura. "Don't go too extreme, like the current trend of a very orange color, if it doesn't look natural." Instead, Laura suggests choosing plum or pink shades of blush, like brownish-pink, peachy-pink or slightly golden tones that create a glow. Don't go too dark or too brown, especially if you have sallow skin, Laura cautions. If you're looking for something darker, however, consider a warm hazelnut or brownish-gold blush.
