Patch-test first. Avoid the eye area and broken skin, and take it off if you notice redness or itching.

  • Before a big day

    “I'm definitely using it the day before anything important.”

    Translated from Korean

  • Stays on while you move

    “I cleaned and stretched with it on, and not a single spot lifted.”

  • Cool, calm feel

    “The next day my skin had a glow and my makeup went on so well!”

    Translated from Korean

From customers in Korea who bought D-1. Translated from Korean and shortened.

The night before

Everyone has a big day coming.

A pitch. A first date. An early flight. A reunion. Photos you'll keep for years. You don't need a ten-step routine for any of them. You need one night, done right.

A pitch A first date An early flight A job interview A reunion Photo day Day one at a new job A wedding An anniversary Graduation A concert A big trip A dinner reservation Filming day

Why DAYBFOR

Most skincare asks for consistency. Every night, forever, and maybe in a few months you'll see something.

DAYBFOR asks for one night.

In Korea, the night before has a name: D-1.

The yesterday layer

By the night before, your skin is carrying the week.

Stress, short sleep, travel and dry air leave a layer on the surface: dull, flaky buildup and oil. It's what makeup clings to and what cameras read as tired. Most night-before fixes just add water on top of it.

  • Foundation catches on flakes
  • Oil breaks through by noon
  • Cameras read it as tired

Why the usual fixes fall short

Most fixes either give or take. D-1 does both.

How it works

It gives. Then it takes.

Bio-cellulose is grown, not pressed — one continuous web that holds on, and changes as it dries.

Holds on
01

Holds on

Peel one mesh, press it on, peel the other. The mesh helps you place it without tearing; then the sheet grips every curve and stays put while you move.

Gives
020–30 min

Gives

A sheet that holds about 50× its weight in essence keeps your skin bathed in it, with a cool, calming feel — stop here for IN 30.

IN 30
Takes
0330–60 min

Takes

As it dries it contracts — skin feels firmer and lifted, and surface oil and dull, flaky buildup lift onto the sheet. That's OUT 60.

OUT 60

Uncomfortably tight? Take it off early — next time, stop at IN 30. Never sleep in it.

Sheet-material lab tests (KATRI): 50× its weight, skin surface about 5°C (9°F) cooler, fibers about 1/1,000 the width of pulp fiber. Not clinical results for the finished product.

Real footage · No filters · Results vary

The rinse test

Feel it hold. Feel it firm. Then see what it lifted.

Rinse the used sheet under water and look closely. What it lifted off the surface stays on the sheet. What shows up varies by skin and day.

  1. Feel it holdIt stays on while you get ready, read or pack a bag.
  2. Feel it firmAs it dries down, the sheet tightens to a firm, lifted feel.
  3. See what it liftedRinse the used sheet. What came off the surface stays on it.

Reviews

Worn before the days that mattered.

What comes up again and again: it stays on. Also the moisture, the glow, and how well makeup goes on after.

“Other 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~!”

Translated from Korean

kim**** Korea · Oct 2026 Before a get-together

“My 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 ^^*”

Translated from Korean

ahn**** Korea · Oct 2026 Oily skin

“The 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!”

Translated from Korean

Verified buyer Korea · Oct 2026 Stays on, even with a beard

“Wash, 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.”

Translated from Korean

Verified buyer Korea · Oct 2026 Peel, press, done

“I 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.”

Translated from Korean

jh33*** Korea · Oct 2026 Bought the 10-pack

“Once 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.”

Translated from Korean

Verified buyer Korea · Oct 2026

“I 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. First time I’ve ever stocked up on masks. When these run out, I’ll stock up again!”

Translated from Korean

Verified buyer Korea · Oct 2026 Second order

“I 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.”

Translated from Korean

Verified buyer Korea · Oct 2026 Dry, sensitive skin

“The day before divorce court I wanted to pamper myself! This mask serum felt great, the mask held in place during a soak in the tub and my skin glowed after. Look out soon to be ex, I am feeling confident.”

Pamela P. United States · Oct 2026 The day before court

“It 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.”

Translated from Korean

Verified buyer Korea · Oct 2026

“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.”

Translated from Korean

Verified buyer Korea · Oct 2026 Bride-to-be

“I’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.”

Translated from Korean

Verified buyer Korea · Oct 2026 Ordered again

“The 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.”

Verified buyerKorea · Sep 2026

“So 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!”

“My makeup went on so well that people asked if I'd switched products.”

“With 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.”

Verified buyerKorea · Sep 2026

“Someone I know gave me one to try, and I liked it so much I bought more. It sticks better than other masks. I do housework with it on and it doesn't fall off. Lots of essence, too. The problem is, my husband keeps using them.”

“This 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.”

Translated from Korean

Verified buyerKorea · Sep 2026

“The 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.”

“I 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.”

“After using the mask, my foundation goes on naturally, like it's sinking into my skin.”

“It 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%.”

The day before divorce court I wanted to pamper myself! This mask serum felt great, the mask held in place during a soak in the tub and my skin glowed after. Look out soon to be ex, I am feeling confident 😉

D-1 Bio-Cellulose Mask

Store owner replied: Pamela, thank you so much for your lovely review! It makes us so happy to hear that the mask helped you feel more confident. For the remaining masks, just a small tip: the bio-cellulose sheet has mesh protection on both sides, so make sure to peel off both mesh layers before applying it to your skin for the best fit and experience. We’ll always be cheering you on for every important day ahead! ✨

FAQ

Before you try it.

Anything else? Email hello@daybfor.com. We reply within one business day.

I'm told never to try anything new before a big day.

Good rule. Try one sheet a week or so before, then use the next one the night before. That's why Box 1 has four.

Could it irritate my skin?

Every batch is safety-screened, but skin is personal. Patch-test first, avoid the eye area and broken skin, and take it off if you notice redness or itching.

How long do I leave it on?

30 minutes for hydration and a cool, calm finish (IN 30). 60 minutes to let it dry down for a firm feel and to lift surface oil and flaky buildup (OUT 60). Go by your skin: oily skin usually does well with the full 60. If your skin is dry, 20 minutes or less may be plenty, and very dry skin can start to feel tight after 10–15. Take it off when it does and follow with moisturizer. Don't sleep in it.

Do I take off both mesh layers?

Yes, both come off: one before the sheet touches your skin, the other as soon as it's on. Peel the mesh off one side, press that side onto clean, dry skin, then peel off the outer mesh. The mesh only helps you place the sheet, so don't wear it with a mesh layer still on.

Why not just a regular sheet mask or a serum?

A regular sheet adds water and slides around. A serum can't take anything away. D-1 holds on, gives, then lifts surface oil and flaky buildup as it dries.

How is it different from my gel mask?

Gel masks give moisture and sit there for hours. D-1 gives, then dries down to a firm feel — and takes what's on the surface with it. One hour, not overnight.

Which box should I get?

Most people start with the subscription: four sheets every month, about one a week, at $6.99 a sheet. Just want to try it once? Get Box 1. Want ten at once? Box 2. Sharing, gifting or stocking up? See our bundles.

Why does it cost more than a regular sheet mask?

Because it isn't a regular sheet. Bio-cellulose is grown by fermentation, not pressed from pulp, and holds about 50× its weight in essence, so it can stay on for up to an hour. It's made for the nights before the days that matter, so you don't need one every night. On subscription it's $6.99 a sheet.

How does the subscription work?

Four sheets every month for $27.95 — 30% off. Free express shipping on every box and a surprise K-beauty mini from your second box. It renews monthly until you cancel. Skip, pause or cancel anytime from your account.

What if it's not for me?

Try Box 1, on its own or as your first subscription box. Not for you? Email us within 30 days of delivery for a full refund — no need to send it back. One Box 1 per customer, on your first order. Refund policy

When will it arrive?

It ships the same business day from Korea and takes 3–5 business days to the US. Have a date coming up? Order about two weeks ahead so it arrives in time to try one a week before. With a subscription, your next box is already on its way.

Will I pay customs?

Our prices include free express shipping but not import duties or taxes. Your carrier collects them on delivery, and we don't add any fees of our own. Details are in our shipping policy.

Can men use it?

Yes, and they do. One early buyer's complaint: her husband keeps using hers. No makeup skills needed: put it on, do something else, peel it off. Sharing? Box 2 has ten.

Your next big day is coming. Be ready the night before.
