What's Actually Soaking Into Your Skin

Low Molecular Hyaluronic Acid That Actually Sinks In
Most hyaluronic acid in drugstore masks sits on top of the skin, giving temporary surface plumpness. Our formula uses low-molecular-weight HA, a smaller molecule that penetrates deeper, drawing moisture into the layers where dehydration starts. It's the difference between a quick drink and an overnight soak.

Collagen And Probiotics For A Resilient Barrier
Low-molecular collagen works with galactomyces ferment filtrate — a fermented yeast derivative beloved in K-beauty — to not just hydrate but actually mend the skin's defense layer. Think of it as reinforcing the mortar between your skin cells, so moisture stays locked in and irritants stay out.

Silky Enough To Sleep In
It sounds too good to be true, but the lightweight, non-sticky fabric really does stay put all night. No sliding off onto your pillow, no gooey residue that makes you want to wash your face. The hydrogel clings gently, and in the morning it peels off cleanly, leaving only the softened, dewy skin behind.

One Sachet, Zero Mess
No jars to dip fingers into, no guessing how much to apply. Each single-use sachet is precisely dosed with enough essence for one full treatment, with a little extra to pat into your neck and hands after. It's the ultimate lazy-girl routine: tear, unfold, relax.
The Numbers Behind The Mask
- 4masks per box
- 15-20 minminimum wear time
- 1sachet per single-use mask
Fifteen Minutes Or All Night — Your Call
- 1Cleanse and tone as usual.
Start with clean, dry skin. No heavy oils or creams underneath — just your regular toner if you use one.
- 2Tear open a sachet and unfold the mask.
The hydrogel sheet is folded inside, soaked in a creamy essence. Peel away the protective film and smooth it onto your face, pressing gently to fit.
- 3Relax for 15-20 minutes — or tuck yourself in.
For a quick boost, leave it on for at least 15 minutes while you scroll, read, or decompress. If wearing overnight, adjust it so it's snug and sleep on your back for best adherence.
- 4Remove and pat in the leftovers.
Peel off the mask slowly — it shouldn't tug. Whatever essence remains on your face and in the sachet, press gently into your skin and neck. No need to rinse.
- 5Wake up glowing — literally.
In the morning, your skin should feel softer, look plumper, and show less fine-line emphasis. If you used it overnight, you can skip morning moisturizer if your skin feels satisfied.

The Story Behind The Mask
- 1The Tight, Tired Feeling By Nightfall
You know the look: skin that feels stretched, papery, almost thirsty by the time you brush your teeth. Makeup sits on top instead of blending, and fine lines linger longer than they did last year. It's the signal that your barrier is losing the moisture it worked to hold all day — and overnight, without help, it'll lose even more.
- 2What Overnight Really Costs Your Skin
While you sleep, transepidermal water loss jumps — it's the silent process that leaves skin duller and more fragile by morning. Without a strong barrier to lock hydration in, the cycle repeats: dehydration, irritation, deeper-looking lines. Drugstore creams sit on top; sheet masks are often rinsed off after minutes. Neither stays long enough to interrupt the damage.
- 3A Sheet Built To Work While You're Unconscious
This isn't a quick-fix sheet. It's a hydrogel mask designed for extended wear — up to eight hours of deep saturation. Low-molecular hyaluronic acid and collagen are sized to sink past the surface, while galactomyces ferment filtrate quietly rebuilds the barrier. The fabric stays non-sticky and in place, so you can wear it under your usual night cream, or alone, and let it do the heavy lifting while you sleep.
- 4Morning Skin, Reimagined
Wake up, peel it off, and pat the leftover essence into your skin. No rinsing. No panic about greasy pillowcases. Just smooth, plump skin that catches the light. Makeup glides on without catching dry patches, and your face looks like it actually got the rest you wish you'd had. Four sachets in this box — four mornings of reimagined skin.

Questions and answers
Yes, it's designed for overnight wear. The hydrogel fabric clings lightly and stays put for the full 8 hours. It's not sticky; it feels like a cool, damp sheet that gradually sinks in. In the morning it peels off cleanly, leaving no residue.
The formula skips alcohol and fragrance. The galactomyces ferment filtrate is actually known for calming and barrier strengthening, so even reactive skin types tell us it feels comforting. Always patch test first, but most sensitive-skin users report no irritation.
Night cream sits on top of the skin; a hydrogel sheet creates a sealed environment that pushes actives deeper over hours. Low-molecular HA and collagen in this formula are small enough to penetrate, not just coat. Plus, the single-dose sachet locks in freshness without preservatives.
Once a week is ideal for maintenance, but you can use two in one week before an event. Most people see a visible difference after the first use, and consistent weekly use builds cumulative barrier strength over a month.
Patting the leftover essence into your skin is usually enough for normal-to-combination skin. Dry skin types can layer a light moisturizer on top if they want extra cushion. No need to rinse.
Absolutely. The mask still delivers a serious hydration boost in 15-20 minutes. Pat in the essence, wait a minute for it to absorb, and apply your makeup as usual. It creates a smooth, hydrated canvas.
