It's often said that the devil is in the details--a maxim that holds especially true when it comes to cosmetics (after all, a single renegade smear can ruin an entire makeup application). Conversely, the right beauty details can instantly take a look it from eh to oooh, so some of the most valuable products are those that play secondary roles, offering little tweaks that pack a wallop without taking center stage. One such product is DuWop's Browwow kit ($34; sephora.com), an easy-to-use compact that makes arches so flatteringly well-defined, it deserves an award for Best Supporting Cosmetic.

The kit includes a dual-sided angled brush for flawless application; powder, to add color and bulk up wimpy brows; a tinted pomade, to smooth stray hairs and add shine; and the cherry on top, a champagne highlighter, to dab on the browbone. Unlike juggling a myriad of products to achieve ocular perfection, Browwow is cleverly proportioned for makeup kits and on-the-go touch-ups. Plus, it comes in two shades, the lighter of which enhanced my blonde brows without looking unnatural. The real test? The first time I rocked my newly perfected arches, my friend stared at me suspiciously: "Did you get your hair done?" No. "Something's different. A facial?" No. And my favorite: "Did you lose weight?" Bottom line: From now on, my brows are now speaking softly and carrying a big ol' stick. --Zoe Stagg
