The Bio-Collagen Real Deep Mask from Seoul is an adhering Hydro-Gel mask that clings to skin like a second layer, absorbs completely and delivers a deep dose of collagen, hyaluronic acid and niacinamide — for hydrated, smooth, plumped skin by morning.
The tiny 243Da collagen molecule — one of the smallest in the world — penetrates deep into pores, refining them, filling out fine lines and smoothing skin texture. A blend of hyaluronic acid oligomers, galactomyces, peptides and 3 types of probiotics strengthens the skin barrier, calms redness and gives a natural glow.
- Adhering Hydro-Gel mask — no rinsing, no stickiness
- Hydration that lasts up to 150 hours after use
- Free from 19 problematic ingredients, EWG-safe

- After cleansing — cleanse your face and apply toner or serum as usual.
- Apply — remove the mask from the pack, peel off the protective layers and gently smooth onto your face from the centre outwards.
- Wait — leave on for at least 3–4 hours or overnight until the mask turns transparent and is absorbed into the skin.
- No rinsing needed — gently remove and follow with moisturiser. Any residue is fully absorbed into the skin.

The result: hydrated, plumped, glowing skin from the very first morning.

I left the mask on overnight and woke up to skin I barely recognised — hydrated, glowing and so smooth. Wish I'd found this sooner.
My skin is sensitive and flakes easily. This mask didn't sting at all, calmed the redness and I noticed a difference by the very first morning.
I use it twice a week in the evening before events — my face looks radiant, pores are less noticeable and even my makeup sits better afterwards.
Frequently Asked Questions
The mask is a serum-rich Hydro-Gel — the longer it's left on, the better it adheres to skin and the more active ingredients it releases. That's why it's ideal for overnight use or 3–4 hours during the day.
Absolutely. Collagen is effectively absorbed at a molecular weight of 500 Daltons or less. Seoul's collagen is just 243 Daltons — one of the smallest on the market — ensuring deep penetration and optimal absorption.
Clinical research showed a 166% increase in skin hydration levels, with the effect continuing for up to 150 hours after use — not just on the surface, but in the deeper layers too.
Yes. The formula is free from 19 problematic ingredients, EWG-safe and dermatologically approved — safe for sensitive skin, and for use during pregnancy and breastfeeding. If in doubt, consult your doctor.
We recommend 2–3 times a week as the final step in your evening routine. You can also use it daily if needed. During seasonal changes or before an event, a full night with the mask on gives an instant glow.
