jh33***, Korea ✓How does it work?
Most sheet masks are pressed cotton or pulp. They dry out, slide and peel away at the corners. D-1 is bio-cellulose, grown by fermentation from coconut water, with fibers about 1/1,000 the width of pulp fiber, so it follows every curve and grips like a second skin.
The sheet holds about 50× its weight in essence* and feeds it in over the hour, so your skin stays soaked the whole time. As it dries it tightens, lifting surface oil and dull, flaky buildup, then peels off clean: no stickiness, no residue.
Because it stays put, you don’t have to lie still. Pack, steam your outfit, run through your toast.
*KATRI lab test of the bio-cellulose sheet material. Not a clinical result for the finished product. Results vary.
What does it feel like?
Cold, weightless and soaked. It sits flat with no lifting at the edges, and the surface of your skin feels about 5°C cooler while you wear it*: calmer and less puffy by morning.
When you peel it off, skin feels moist, soft and bouncy, never sticky. It’s the calm of a high-end facial, at home, in one hour.

When and how often should I use it?
Any night before a day that matters to you: a wedding, an interview, a Monday meeting, a dinner with old friends, or just a day you want to feel good about. You decide which days count. New to D-1? Try your first sheet on a quiet night.
- Cleanse and pat dry. Skip the toner: the sheet brings its own 20 ml of essence.

- Peel (dampen it first if it has dried), press the leftover essence in, go to bed.
- How many a month? Just the big days: 4. A few nights a week: 12 (Buy 2, Get 1 FREE). Most nights: 20 (Buy 3, Get 2 FREE).

A friend recommended it, I tried one, and I bought my own. The sheet is thin, but it grips and follows every curve of my face. I dried my hair and did housework with it on and it never came off. I’m a bride-to-be, and I wore it the night before meeting my fiancé’s parents. My mom asked what happened to my skin. I’m gifting one to my mother-in-law. Perfect for the night before anything important.
Korea · Oct 2026 · Bride-to-beOther sheet masks feel like they lift a little, but this one clung to my face. I left it on for over 30 minutes, and when I peeled it off my skin felt firmer. I have a get-together with friends tomorrow for the first time in ages, so I used it tonight. Hydration goes without saying, and it feels like the flaky bits are cleared up and my skin texture is different. Love it!
Korea · Oct 2026 · Before a get-togetherMy skin hasn’t been smooth lately and my oil shows, so I’ve been trying all kinds of masks. Then I finally found a really good one. Usually you need one mask for nourishment and a separate one for oil, but this one does several things at once. For the first 20 minutes it feels like it’s feeding my skin, and by 60 minutes it takes care of the oil and feels like it tightens everything up. At first I thought it was just one thin sheet, but peel gently and the mesh comes off. It sticks snugly over my whole face, and it doesn’t drip even while I go about my day. It’s so thin it sticks with no gaps. I want to keep rebuying.
Korea · Oct 2026 · Oily skinI actually really enjoyed using this mask, especially because it requires long-term application. I used it while I was folding laundry and it never moved from my face. It left my skin feeling so refreshed and glowing.
United States · Sep 2026The perfect SOS fix before an important day. I have a beard, so other sheet masks fall off or never really stick, but DAYBFOR somehow clung right on! My skin was in great shape the next day. Recommend!
Korea · Oct 2026 · Stays on, even with a beardSo moist, and it sticks right to your face. The next day my skin had a glow and my makeup went on so well! I think I’ll keep buying these. A must before a big day, but I think I’ll use it daily too!
Korea · Sep 2026 · Repeat buyerI have zero interest in skincare. Masks and lotions everyone raved about never did anything for me. Then I happened to try a DAYBFOR mask and I was shocked. When I washed my face the next morning, my skin was so soft I kept going back to the mirror. I’d go 60 minutes over 30. It’s the first beauty product I’ve ever actually felt a difference from, so I stocked up with my own money. When these run out, I’ll stock up again!
Korea · Oct 2026 · Second orderI really like these masks! They’re easy to use, and I left them on for about 60 minutes. By the end, all the product was dry on my skin. My skin looked brighter and felt hydrated, but not sticky at all.
United States · Sep 2026I bought it on a friend’s recommendation. The sheet is thin and clings right to my face. After peeling, no stickiness at all, just moist, soft skin! Other masks feel like they sit on top of my skin, but with this one the essence feels like it sinks in. I love it. I’ll keep using it.
Korea · Oct 2026 · Bought the 10-packThe fit is unreal. I cleaned and stretched with it on, and not a single spot lifted. I’m not into beauty stuff at all, and even I can tell this mask is good. Buying again when I run out.
Korea · Sep 2026I almost never write reviews, but this one is a real find. I’m in my early 30s with very dry skin underneath and a lot of heat and redness, so I react to anything harsh. This sheet cools, calms, hydrates and takes care of oil in one go, with zero irritation. Other masks drip their essence everywhere; this sheet holds it all so my skin actually drinks it in. It sticks so well that I don’t have to lie down, so I get other things done while it’s on. The difference shows on my face the next day.
Korea · Oct 2026 · Dry, sensitive skinIt is really good, gives a beautiful glow and makes the skin hydrated! Thank you so much daybfor
Switzerland · Oct 2026My makeup went on so well that people asked if I’d switched products.
Korea · Sep 2026Wash, peel, press it on, and that’s basically my whole routine. So easy. I wake up with a glow, and my pores feel tighter. It’s simpler than layering this and that, and I can actually see the results. I thought it was a bit pricey, but it works out about the same as buying several skincare products, so it’s good value. Honestly, really good.
Korea · Oct 2026Thank you so much! I really loved this mask. It leaves my skin feeling deeply hydrated and moisturized, which I especially appreciate during this time of year when my skin tends to get much drier. I really enjoyed using it!
South Korea · Sep 2026With mesh on both sides it never curled up like my cotton masks, and the fit was excellent, even on a larger face. Around 30 minutes in, I could feel a cool, moisturizing sensation sinking into my skin, and it felt like my pores were tightening. This weather had left my face warm and noticeably flaky, and both disappeared like they’d never been there.
Korea · Sep 2026Once the mask is on, it feels like it’s gently pulling my skin toward the center, and my tired, loose-feeling skin feels taut. The sheet is so thin it clings right to my face. Peeling it off is like peeling the thin skin off the inside of an eggshell. My skin felt bouncy afterward. I felt younger, and it put me in such a good mood.
Korea · Oct 2026This is different from other sheet masks. Even after 30 to 60 minutes on, the serum doesn’t drip. I’m definitely using it the day before anything important.
Korea · Sep 2026I’ve been a mask nomad for years, and I’m settling down with this one. Every ‘good’ mask I tried left my face sticky, which I hate. This one is different: no stickiness at all right after peeling, and my skin is so hydrated, like I’d put on a really good treatment. My face is glowing. There was plenty of essence left, so I used it on my neck. Ordering more right now.
Korea · Oct 2026 · Ordered againThe bouncy, jelly-like sheet sits perfectly against your skin, so even with a long wear time it’s easy to go about your day, and the essence feels like it absorbs fast. It finishes clean, with no sticky or heavy residue, so you can do your makeup afterward. The only downside: it’s a bit pricey.
KoreaAfter using the mask, my foundation goes on naturally, like it’s sinking into my skin.
Korea · Sep 2026 · Bought againWith other masks I need one for oil and another for hydration. This one does both. I planned to try four masks over a month and buy again if they worked, but I liked them so much I’d already used two in the first week.
Korea · Sep 2026It fits perfectly with no lifting at all. It really sticks, so it doesn’t come off even when I move! After using it, my skin texture and tone seem brighter, so I love it.
Korea · Oct 2026Better than any mask I’ve used, by far. I usually skip masks because I hate how sticky my face feels after. This one isn’t sticky at all, just moist.
Korea · Sep 2026I’ve never had a mask fit like this. Other masks always had a spot that lifted, and this one feels so nice on the skin. Bought more right away. Highly recommend!
Korea · Sep 2026 · Bought againIt grips so well I could get on with everyday things with it on. The sheet itself is bouncy and feels like it’s holding my skin firm, and it felt like my whole face was being lifted upward. Afterward my skin felt brighter and plumper. One tip: if your skin is dry, take it off within 20 minutes. I’d buy it again, 100%.
