Argan oil has long been touted for the shine-enhancing and hydrating properties it provides to hair. But when it comes to skin, this potent beauty ingredient works just as impressively. Josie Maran's Argan Exfoliating Powder ($35) is a gentle exfoliant that not only buffs away dead skin cells, but also hydrates and smooths your complexion, leaving a healthy glow behind. To use, add a few shakes to your hand and mix in some water to form a creamy paste. It's gentle enough to apply daily for those with normal skin, while people with more sensitivity should use it less. Whatever your skin type — or disposition — it's guaranteed to make you feel totally renewed.
