How it works
The Black Snail Restore Serum is a 50ml serum, used after toner and before moisturizer, morning and evening. The humectant it is built around is Snail Secretion Filtrate, named first 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 serum format rather than by the list alone. This is the Original Korean Formula, the serum IUNIK sells in Korea, Snail Secretion Filtrate and all.
Key benefits
- Snail Secretion Filtrate, the humectant this serum is built around
- Niacinamide, Allantoin and Adenosine on the same list, actives
- Laminaria Japonica Extract on the same list, a plant extract
- Glycine Soja (Soybean) Seed Extract and Oryza Sativa (Rice) Extract further down the same list
- Sesamum Indicum (Sesame) Seed Extract and Solanum Melongena (Eggplant) Fruit Extract further down the same list
- Snail Secretion Filtrate named first on the manufacturer list printed on this page
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. 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 serum or a US version?
The Korean-market one, Snail Secretion Filtrate and all. We match this serum 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 serum'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: Laminaria Japonica Extract, Glycine Soja (Soybean) Seed Extract and Oryza Sativa (Rice) Extract.

33 of 33 explained
- Snail Secretion Filtrate (70%) 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.
- Centella Asiatica Leaf Water (10%) plant extract
- Centella Asiatica Leaf Water is the distilled water of the centella leaf, used in place of plain water as a formula base. It is far more dilute than the extract, so it sets the base rather than supplying the actives.
- Methylpropanediol humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- 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.
- 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.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- 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.
- 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.
- Saccharomyces/Viscum Album (Mistletoe) Ferment Extract ferment
- Mistletoe fermented with yeast, then extracted. Fermentation breaks the plant material down into smaller sugars and peptides, and the extract is used as a conditioning ferment.
- Lactobacillus/Soybean Ferment Extract ferment
- This is soybean fermented by lactobacillus. The fermentation breaks soy proteins into smaller pieces, which is what makes the extract easier for a formula to carry.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
21 more explained
- Glycine Soja (Soybean) Seed Extract plant extract
- Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
- Oryza Sativa (Rice) Extract plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- Sesamum Indicum (Sesame) Seed Extract plant extract
- Sesame seed extract. It carries sesamol and sterols and is used as a conditioning, antioxidant-rich extract.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- Saccharomyces/Imperata Cylindrica Root Ferment Extract ferment
- Cogon grass root fermented with yeast, then extracted. The root is used in formulas for its water holding sugars and potassium, and fermentation makes them more available.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- 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.
- 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.
- Centella Asiatica Extract plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Artemisia Vulgaris Extract plant extract
- Common mugwort extract. It is the same genus as the Korean mugwort artemisia princeps and is used for the look of reddened, reactive skin.
- Vaccinium Angustifolium Fruit Extract plant extract
- Lowbush blueberry fruit extract, high in anthocyanins. Berry extracts are used as plant antioxidants and can tint a formula.
- Ginkgo Biloba Leaf Extract plant extract
- Ginkgo leaf extract, carrying flavone glycosides and terpene lactones. It is one of the most studied plant extracts and is used as an antioxidant.
- Rosa Canina Fruit Oil emollient
- Rosehip oil, pressed from the fruit of the dog rose. It is high in linoleic acid and carotenoids and is used for the look of marked, uneven skin.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Pentylene Glycol humectant
- Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
- 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.
- 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.
- 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.
- Aspalathus Linearis Extract plant extract
- Rooibos extract, from the South African red bush. It carries aspalathin and other flavonoids and no caffeine, and it is used as a plant antioxidant.
