Beauty Obsession: YSL Touche Éclat Radiant Touch

YSL Touche Éclat Radiant Touch ($41, ysl.com) is a cult beauty favorite with celebrities and makeup artists, and with good reason: its light-reflecting particles banish even the darkest shadows. After test-driving, I found that my entire face looked brighter and more well-rested, even during a nasty bout with the flu. You can apply it down the center of the nose, above and beneath the eyebrows, the inner corners of your eyes, the top of your cheekbones, laugh lines or outline your lips. Happy highlighting!
