How it works
The Advanced Snail Mucin Glass Glow Hydrogel Mask_ is a 1ea sheet mask, used after toner, in place of your serum step, in the evening. The humectant it is built around is Snail Secretion Filtrate, named second on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, so the humectant is not the only thing on it worth naming. How much of the Snail Secretion Filtrate stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. This is the Original Korean Formula, the sheet mask COSRX sells in Korea, Snail Secretion Filtrate and all.

Key actives
Snail Secretion Filtratehumectant
Snail Secretion Filtrate is the mucin a snail produces, filtered for cosmetic use, and it is the ingredient the Korean snail category is built on. It carries glycoproteins, hyaluronic acid and glycolic acid, and it is used for hydration and a smoother-looking surface. The name on the box points at it, and it is named second on this sheet mask's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fifth on this sheet mask's list, alongside Snail Secretion Filtrate.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. It is named seventeenth on this sheet mask's list, alongside Snail Secretion Filtrate.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. It is named twenty-first on this sheet mask's list, alongside Snail Secretion Filtrate.
Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. The panel names it twenty-eighth on this sheet mask's list, beside Snail Secretion Filtrate.

Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Snail Secretion Filtrate and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Snail Secretion Filtrate and all. We match this sheet mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Snail Secretion Filtrate?
Niacinamide, Allantoin and Adenosine. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Snail Secretion Filtrate sits relative to them. Further down the same panel: Gluconolactone, Tocopherol and Ceramide NP.

How to use
- Use the Advanced Snail Mucin Glass Glow Hydrogel Mask_3ea after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Snail Secretion Filtrate on the list.
- Gluconolactone on this list makes this sheet mask an exfoliating step, so do not stack it with another one on the same night.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
