How it works
A hydrogel patch works by staying put: it sits against the thin skin under the eye and holds a gel there, which is something a cream rubbed in cannot do. The gel here is set with carrageenan, carob gum and guar gum, and it carries snail secretion filtrate, niacinamide, allantoin and adenosine. It goes on clean skin before serum, morning or evening, and the gel left on the skin afterwards gets pressed in. An under-eye that looks creased and tired when it is dry is the case this fits. Use it two or three times a week alongside an eye cream rather than instead of one.
Key benefits
- Snail secretion filtrate sits third on the list, niacinamide fourth
- The patches come in a smaller and a larger cut to fit the eye area and smile line
- Licorice-derived dipotassium glycyrrhizate keeps the formula calm
- A cool hydrogel that plumps the look of the under-eye before makeup
Inside the formula
Inside the formula
COSRX Advanced Snail Hydrogel Eye Patch
What is the gel material in this eye patch made from?
Carrageenan leads the gelling system, along with carob gum, guar gum and cellulose gum, all seaweed and plant-derived thickeners used to hold the hydrogel's shape and keep it in contact with the under-eye area during wear.
Where does snail secretion filtrate sit on this patch's ingredient list?
Third, right after water and glycerin. That is a high position for an eye patch, meaning the snail filtrate is a substantial part of the formula rather than a minor addition for the label.
Does this patch contain niacinamide?
Yes, niacinamide sits fourth on the list, directly behind water, glycerin and the snail filtrate. It supports the brightening-adjacent positioning common to snail mucin under-eye patches, and applying the patches to clean, dry skin gives it the best contact time to do that work during the wear window.
How long should these patches stay on?
Hydrogel eye patches built on a gelling system like this one are typically left on for fifteen to twenty minutes while the gel is still cool and moist, then removed before it starts to dry and pull moisture back out of the skin.
Is there anything soothing beyond the snail filtrate in this formula?
Yes, allantoin and dipotassium glycyrrhizate, a licorice root derivative, both appear on the list to support a calm, non-irritating feel alongside the snail filtrate and niacinamide. Applying the patches to clean, dry under-eye skin and leaving them for the full wear window lets that soothing pairing settle in before the gel is peeled away.

20 of 21 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.
- 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.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- Carrageenan thickener
- Carrageenan is a red-seaweed polysaccharide that thickens and forms a moisture-holding film. It gives a formula a slippery, cushioned body.
- 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.
- Ceratonia Siliqua (Carob) Gum thickener
- Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- 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.
- 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.
- Chlorphenesin preservative
- A preservative effective against bacteria, yeast and mould across a wide pH range, which is why it appears where a single milder preservative cannot cover the formula.
- Cyamopsis Tetragonoloba (Guar) Gum thickener
- Guar Gum is a seed polysaccharide that thickens and stabilises. It also leaves a conditioning film that makes skin feel smooth.
8 more explained
- Calcium Chloride mineral
- Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.
- 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.
- Sucrose humectant
- Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
- Cellulose Gum thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- Adenosine active
- 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.
- Potassium Chloride mineral
- Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
- 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.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.

How to use
- Use the Advanced Snail Hydrogel Eye Patch on clean skin, before serum, morning or evening.
- One patch under each eye, smoothed outward from the inner corner until the edges lie flat.
- Leave them for the time the pack gives, pat in what the gel leaves behind, then go on with serum and moisturizer.
- Two or three times a week. Do not stretch a patch to reach further across the cheek; one that has been pulled will not sit flat.
Worth knowing
- Snail secretion filtrate is animal-derived, so this is not a vegan formula.
