How it works
A cellulose sheet mask is the simplest way to keep an essence against the face for a set number of minutes, and a ten-pack is bought to be used regularly rather than saved. This one is soaked in an essence built on snail secretion filtrate, with panthenol, sodium hyaluronate and allantoin behind it and a little tea tree leaf oil on the same list. It goes after toner, in place of the serum step, and the essence left on the face afterwards is patted in. Skin that feels tight by the end of the evening is the case a hydrating sheet answers. Two or three evenings a week is a normal rhythm for a pack this size.
Key benefits
- Snail secretion filtrate sits fourth on the list, ahead of the preservative system
- Panthenol and sodium hyaluronate carry the hydration
- Licorice-derived dipotassium glycyrrhizate keeps the soak calm
- The cellulose sheet hugs the face closely so the essence stays put
Inside the formula
Inside the formula
COSRX Advanced Snail Mucin Power Sheet Mask 10 Sheets
How is this mask different from a more elaborate snail mucin hydrogel mask?
This is a fabric sheet mask soaked in a thinner essence, with snail secretion filtrate fourth on a list of under twenty ingredients, compared to a hydrogel format that carries a heavier gel matrix and often more ingredients overall. Both use the same core snail secretion filtrate as their lead active, but the sheet format delivers it in a lighter, faster-absorbing essence.
What is dipotassium glycyrrhizate doing in this formula?
It is a licorice-root derived soothing compound and sits in the latter half of the ingredient list alongside allantoin, the mask's calming pairing. It is a common Korean-formula inclusion for taking the edge off a mask session on skin that runs reactive.
Does this pack include enough sheets for regular use?
The pack contains ten individually wrapped sheets, which supports a few uses a week for over a month rather than a single trial. Each sheet is sealed on its own, so unopened sheets in the pack are not exposed to air until used.
Is there fragrance in this sheet mask?
No parfum or fragrance ingredient appears on the list. Any scent that is noticeable would come from the base humectants and the snail secretion filtrate itself rather than an added fragrance compound.
Can this mask be used every night?
The formula is built around humectants, snail secretion filtrate, panthenol, and allantoin, all of which are generally well tolerated with frequent use, so nightly use is reasonable for skin that tolerates it well. Anyone new to the product should start a few times a week and watch how skin responds before moving to daily use.

19 of 19 explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Glycerin humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- Snail Secretion Filtrate humectant
- 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.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- Hexylene Glycol solvent
- Hexylene Glycol is a solvent and light humectant. It keeps ingredients that resist water in solution and thins a formula so it spreads evenly.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- Allantoin active
- 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.
7 more explained
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Sodium Hyaluronate humectant
- Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Melaleuca Alternifolia (Tea Tree) Leaf Oil fragrance component
- Tea Tree Leaf Oil is an essential oil from an Australian shrub, carrying terpinen-4-ol. Korean formulas use it in products aimed at blemish-prone skin; it is potent, aromatic, and one of the essential oils most likely to bother reactive skin.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.

How to use
- Use the Advanced Snail Mucin Power Sheet Mask after toner, in place of your serum step, in the evening.
- Unfold one sheet, set it at the eyes and nose first, then smooth it out to the jaw so it lies flat.
- Take it off at the time printed on the pack, pat in the essence that is left, then go on to moisturizer.
- Two or three evenings a week. Do not leave it on until it dries out; a dry sheet takes water back off the face.
Worth knowing
- Snail secretion filtrate is animal-derived, so this is not a vegan formula.
