The Biggest Ingredient in Beauty Has Been in Your Glass This Whole Time

Similar to how a tired, hungover you might ravenously chug a cold glass of water after too late a night, this H2O+ Beauty Oasis Water-Infused Gel Eye Mask ($3) provides a surge of moisture for your puffy, post-drinking undereye area. Plus, the soft, squishy gel patches come in a dry fabric packaging to hold in the serum, so it won't slide all over your face when you use it — which is great because, you've gotta admit, that's a pretty big headache.
