Getting the right amount of glow from blush is all about balance. Add too much, and you risk an unnatural disco-ball sheen. Too little, and the sought-after effect goes missing. Get it right, though, and you're rewarded with a flattering flush of color with a satiny finish. Applying luminizer underneath a cheek stain or sheer matte blush is one way to tip the scales in your favor, but Benefit's newest blush, Hervana ($28), is a one-step solution. Swirl the accompanying brush in its four hues, and they blend together to create a soft pink color with a satiny finish — especially pretty on very fair complexions. Hervana lands on counters next month, but today, Benefit is holding a one-day flash sale for those who just can't wait for their next face powder.
