If you don't have a hydrating serum in your arsenal, then we seriously need to talk. Not only does it make your complexion plump and dewy instantly, it also helps skin stay smooth, soft, and youthful long-term. And our H2Glow Hydrating Facial Serum has a slew of other benefits, too. Besides hydrating hyaluronic acid and vitamin B5, it also features refining willow bark extract, brightening niacinamide and licorice root extract, and protective antioxidants.

Another point in favor of hydrating serums: As refreshing as they already are, there are a number of fun ways to use them to keep cool when the weather heats up. Read on for some of our favorites.

Serum droplets

Stash it in the fridge.

Mini skincare fridges are trending, but who needs 'em? Instead of shelling out the extra cash, stash your serum in your kitchen refrigerator. (You can even designate a special shelf for skincare.) Then, when you get home on a hot day, you'll have an icy-cold complexion pick-me-up waiting for you—right beside a bottle of rosé.

Apply it after a mist.

Facial mists feel amazing during the summer months, but if you apply them without topping them with something else, they can actually pull moisture out of your skin as they evaporate. Lock in hydration with H2Glow afterwards, when your skin is still slightly damp, and the mist will help suck in the serum's ingredients like a magnet.

CLOVE AND HALLOW H2Glow Hydrating Facial Serum

Ice up first.

Like we mentioned above, applying skincare when your face is still damp makes all your products penetrate more deeply. On extra hot days, after you wash your face, gently rub an ice cube over your complexion, then immediately apply your serum. The water's temp will also help temporarily shrink pores and combat any redness.

DIY a sheet mask.

Hot tip (ha, see what we did there?): Dry sheet masks with zero product on them are available in bulk on Amazon, ready to be used with any of your favorite serums, toners, or essences. Load one up with a dropper's worth of H2Glow, apply the sheet mask, and let the ingredients soak in for 15 to 20 minutes.

Roll it on with a gemstone roller.

Sure, these tools are all over Instagram, but they do have some real de-puffing and circulation-boosting perks—plus a serious chilling sensation. Rose quartz is especially known for staying cool, even if it's stored at room temperature. Apply your serum as usual, but instead of patting it in, reach for your gemstone roller and roll all over your face and neck in an upward motion.
