Beauty Gizmos That Really Work

Clear Lip Liner?

When a makeup artist suggested recently that we try an "invisible" lip pencil, we wondered whether she'd gone a little light in her (Gucci) loafers. But she hadn't: Clear lip liner can keep the contour of your lipstick defined without looking harsh or artificial, says Cristina Bartolucci, the cofounder and creative director for DuWop Cosmetics. Apply the liner before your lipstick and you create a physical barrier that blocks the color from seeping into those teeny vertical lines around the lips, so your color stays neat. And because clear liner is undetectable, you'll never worry about having a ring around your mouth once your lipstick fades.

Ensure that your lipstick stays put with Benefit D'Finer D'Liner ($18).
