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

You could spend 30 minutes shvitzing in a steam room or squeezing lemons that really belong in your water cup onto your ankles, or you could spray on the Tan-Luxe Glyco Water Self-Tan Eraser ($33) whenever you need to remove your self-tanner in a pinch. Like the fancy waters you'll find at most grocery stores, this one is packed with vitamins B, C, and E, plus glycolic acid to break down the gilded color in mere minutes.

This is not your average facial water: the Sulwhasoo Concentrated Ginseng Renewing Water ($82) contains steamed ginseng concentrate that goes on like a gel — meaning, it doesn't run in the slightest — but bursts into tiny liquid droplets as you smear it across your skin. The result is a softer, more hydrated visage.

Think of Laneige Water Sleeping Mask ($25) like a swig of water for your skin: it keeps you looking alive. Slather it on before bed and let the formula — which is spiked with ionized mineral water and brightening apricot and primrose extracts — provide the a.m. pick-me-up.

Dry shampoo may prevent fourth-day hair from looking like the lop layer of a Digiorno pizza, but The One Signature Hair Water ($10) is a completely different style reviver — and anyone with curls, frizz, or dry ends needs it all the same. Part water, part lightweight oils, this fine mist adds a hit of hydration and removes kinks and creases from a ponytail so you can create a new style from scratch.

Primer waters in mist form aren't new, but the cool, point-tip applicator in Touch in Sol's No Poreblem Priming Water ($23) makes using the stuff way easier to control. Come for the anti-inflammatory properties you get from its 100 percent undiluted rose water, stay for how it feels like sniffing flowers in the Bagatelle Gardens every time you use it.

Not to sound too much like a pop quiz in chemistry class, but what do you get when you put sodium hyaluronate and hydrolyzed protein with some eucalyptus oil? Answer: Tuél's new Triple Splash 3 in 1 Hydrating Body Tonic ($34), which is meant to be used like a facial toner, only it's for your body, and it smells just as spa-like as it is soothing on skin.

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.

SpongeBob SquarePants was somehow immune to water's immensely plumping effect, but your hair definitely won't be with Tresemmé Thick & Full Micellar Shampoo ($4). This sudser penetrates the hair fiber and binds water for a full-on volume boost without a trip to the salon.

Guided color need not apply: the St. Tropez Self Tan Purity Bronzing Water Mousse ($42) features a water foam formula that goes on clear and dries into a soft, streak-free tan within just a few hours. It's so lightweight, you'll barely know it's there (until, you know, you look in a mirror).

Bath & Body Works Illuminating Rose Water Face Sheet Mask ($5) is like a face mist in sheet mask form, if the former also happened to smell like a flower bouquet on a warm, Summer day.
