This Moisturizing Treatment Claims To Leave Skin 290% More Hydrated After a Single Use—1,000 Five-Star Reviews Agree

During the coldest days of winter, your skin needs extra moisture to make up for the lack of moisture in the air, which means that oftentimes your usual serums and moisturizers just won’t cut it. These dry, desperate times call for desperate measures, which means you may want to kick your complexion-nourishing regimen up a notch with a hydrating mask like GLAMGLOW THIRSTYMUD™ 24-Hour Hydrating Treatment Face Mask ($60).

GLAMGLOW THIRSTYMUD™ 24-Hour Hydrating Treatment Face Mask — $66.00

With more than 1,000 five-star reviews on Sephora’s website, this mask is exactly the tall drink of water your winter skin has been thirsting for. It serves double duty in quenching hydration and strengthening the skin barrier, which is important for keeping all of that oh-so-important moisture locked beneath the surface of your complexion.

First up on the ingredients list is hyaluronic acid, which you may know for its ability to hold 1,000 times its weight in water. This powerful humectant draws moisture beneath the skin—think of it as a heavy-duty sponge—and holds it there throughout the day. This surge of H2O also makes skin look instantly more plump, which helps diminish some of the fine lines and “crinkles” that tend to pop up when your skin is extra dry. Next on the list is coconut extract, which is rich in fatty acids and B vitamins that help fortify the barrier of your skin; and ginger extract, which is rich in antioxidants that protect skin from environmental aggressors (like pollution and UV damage), and stave off free radical damage. Together, these three ingredients make skin feel smooth and nourished—which isn’t an easy feat when temps are dipping below freezing.

The mask can be used as a 10-20 minute treatment before you apply your standard moisturizer, or can be left on overnight as a sleeping mask. And your face isn’t the only place that you’ll be able to reap its hydrating benefits: According to the brand, you can also use it on your hands, feet, or limbs—really, anywhere your dry skin needs an extra dose of moisture.

In a 12-person clinical trial conducted by Glamglow, participants saw a 290 percent increase in the hydration of their skin after a single application. Since the trial was fairly small, though, it’s unclear whether or not you should expect to see the same results in your own skin. But that said, reviewers make it clear that this stuff really lives up to the hype. “Whenever my skin feels dull and dry this helps bring it back to life,” writes one fan of the product. “So happy that I finally found something that helps with my dry winter skin. My skin [is] so soft and the glow is EVERYTHING,” agrees another, who also notes that it’s “worth every penny.”
