Since 2024, I haven’t stepped foot on an airplane without one thing in tow: a sheet mask, more specifically, one of the gel masks from Biodance. They’re a unique construction compared to all the others on the market (now, many brands are doing the gel mask thing, but Biodance really was the first). It comes in two sheets made out of hydrogel that are cooling and slippery to the touch, and after a few hours on your face, it turns clear.

I'm a beauty editor with access to about every single face mask ever made—and I can confidently say this one outperforms all of them. Which is why I’m so stoked that it’s on sale for Amazon Prime Day at 25% off.

Trust me: I've been scouring Amazon for the best deals all week in preparation for Prime Day, and there are a lot of meh ones out there. But this face mask is currently just over $14 for four masks. Not saying you should be prepared for it to sell out, but not not saying that either, ya know?

But what gives it this outrageous glow, huh? First of all, it's got hyaluronic acid to help pull water into your skin to make it look plump and ~juicy~, while collagen helps moisturize your face so it looks bouncy. Niacinamide also helps soothe irritation, clear pores, and gently brighten your skin. Oh, and there's galactomyces, a super-hydrating, antioxidant-rich type of yeast that can help improve skin elasticity. Yup, it's basically filled with a powerhouse of ingredients your face will looove.

There are actually a few options, though. My go-to is the Refreshing Sea Kelp Real Deep Mask, which is soothing and refreshing for my inflamed, acne-prone skin. But there’s also Rejuvenating Caviar PDRN Real Deep Mask to firm and plump, as well as Hydro Cera-Nol Real Deep Mask with hyaluronic acid and ceramides for mega moisture.

Here's how to use it: At the end of your skincare routine in the evening, place the mask over your face. You'll notice that it's already cut in two pieces to help it fit perfectly over your face (which I loved sm). Then, just go to sleep. That's it. In the morning, you'll notice the mask has absorbed and is completely clear. Just remove it and go on with your usual morning skincare routine. You can also use this during the day, but keep in mind you should leave it on for three to four hours (or until it becomes transparent) for the best results.

I’ve used these countless times over the years (peek at some of my selfies above, lol), and they make my skin look so juicy. I’ll wear it on overnight flights and wake up actually looking hydrated—a phrase I absolutely never thought I’d utter in a million years with how drying airplanes can be. But even not on flights, I’ll pop one of these on while I’m working from home so I feel fresh and bright for a night out. And I can’t lie: I love a morning shed with this on days I want to feel like my best self.

Convinced? I thought so! But don’t wait to snag these, because I’m convinced they’ll sell out at this price.
