Where does this lotion go in my routine?

As the last skincare step, morning and evening, over serum. Anything thinner than a lotion 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.

What else is on the list besides Snail Secretion Filtrate?

Adenosine, Copper Tripeptide-1 and Ceramide NP. The order they are printed in on this lotion'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: Hydrolyzed Collagen, Beta-Glucan and Biosaccharide Gum-1.

How it works

The ULTRA S4 Snail Emulsion is a 150ml lotion, used as the last skincare step, morning and evening, over serum. The humectant it is built around is Snail Secretion Filtrate, named thirteenth on its own ingredient list. The same list carries Adenosine, Copper Tripeptide-1 and Ceramide NP, 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 lotion format rather than by the list alone. DEWYTREE sells this Snail Secretion Filtrate lotion in Korea, and this is that version.

Key actives

13Snail 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 thirteenth on this lotion's own ingredient list.

All products with Snail Mucin

27Adenosineactive

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. The panel names it twenty-seventh on this lotion's list, beside Snail Secretion Filtrate.

All products with Adenosine

46Copper Tripeptide-1peptide

Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines. It is named forty-sixth on this lotion's list, alongside Snail Secretion Filtrate.

All products with Copper Tripeptide-1

47Ceramide NPbarrier lipid

Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. The panel names it forty-seventh on this lotion's list, beside Snail Secretion Filtrate.

All products with Ceramide NP

63Hydrolyzed Collagenprotein

Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film. The panel names it sixty-third on this lotion's list, beside Snail Secretion Filtrate.

1 of 4

64 of 66 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.
Cetyl Ethylhexanoate emollient: Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
Propanediol humectant: Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
Hydrogenated Poly(C6-14 Olefin) emollient: Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.
Caprylic/Capric Triglyceride emollient: Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
Cyclopentasiloxane silicone: Cyclopentasiloxane is a volatile silicone: it spreads a formula thin and smooth then evaporates, leaving no residue. It is the silicone behind a dry, powdery primer finish.
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.
Cetearyl Alcohol fatty alcohol: Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
Stearyl Dimethicone silicone: A silicone wax, solid at room temperature. It thickens silicone and oil phases and helps a formula resist water.
Cyclohexasiloxane silicone: Cyclohexasiloxane is a volatile silicone used for a light, fast-spreading feel that leaves nothing behind.
Dimethicone silicone: Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.

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.
Cetearyl Olivate emulsifier: Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
Butyrospermum Parkii (Shea) Butter emollient: Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
Trehalose humectant: Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
Sorbitan Olivate emulsifier: Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
Sorbitan Stearate emulsifier: Sorbitan Stearate is a mild emulsifier and thickener used to hold oil and water together in creams.
Sucrose Cocoate emulsifier: Sucrose Cocoate is table sugar joined to coconut fatty acids. It is a very mild emulsifier and cleanser that also holds water, so it turns up in gentle cleansers and toners.
Glyceryl Stearate emulsifier: Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
Palmitic Acid fatty acid: Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
Stearic Acid fatty acid: Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
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.
Tromethamine pH adjuster: Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
Aloe Barbadensis Leaf Extract plant extract: Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
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.
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.
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.
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.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
Chamomilla Recutita (Matricaria) Flower Extract plant extract: Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
Nelumbium Speciosum Flower Extract plant extract: Lotus flower extract, from the same sacred lotus as the leaf. It carries flavonoids and sugars and is used as a conditioning, hydrating extract.
Phosphatidylcholine emulsifier: Phosphatidylcholine is the main phospholipid in lecithin and in cell membranes. It emulsifies and forms the liposome walls a formula uses to carry an active.
Vaccinium Macrocarpon (Cranberry) Fruit Extract plant extract: Cranberry fruit extract, acidic and high in proanthocyanidins. It is used as an antioxidant berry extract.
Rubus Idaeus (Raspberry) Fruit Extract plant extract: Raspberry fruit extract, carrying fruit acids, sugars and anthocyanins. It is used as an antioxidant-rich conditioning extract.
Cornus Officinalis Fruit Extract plant extract: Japanese cornel dogwood fruit, the sansuyu of Korean herbal medicine. Its extract carries fruit acids and iridoids and is used as a conditioning extract.
Punica Granatum Fruit Extract plant extract: Pomegranate fruit extract, carrying ellagic acid and punicalagins. It is used as a plant antioxidant.
Camellia Sinensis Leaf Extract plant extract: Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
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.
Perilla Frutescens Leaf Extract plant extract: Kkaennip, the perilla leaf eaten across Korea. Its extract carries rosmarinic acid and is used as an antioxidant conditioning extract.
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.
Houttuynia Cordata Extract plant extract: Houttuynia Cordata is heartleaf, and it is one of the two or three anchor plants of Korean calming skincare. Its extract carries quercitrin and other flavonoids and is used for the look of redness and blemish-prone skin.
Salvia Hispanica Seed Extract plant extract: Chia seed extract. Chia seed swells into a gel in water, so the extract hydrates and leaves a cushioned feel.
Biosaccharide Gum-1 polysaccharide: Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
Copper Tripeptide-1 peptide: Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
Ceramide NP barrier lipid: Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
Glycine amino acid: Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
Glutamic Acid amino acid: Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
Serine amino acid: Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
Lysine amino acid: Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
Alanine amino acid: Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
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.
Threonine amino acid: Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
Proline amino acid: Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
Betula Platyphylla Japonica Juice plant extract: Betula Platyphylla Japonica Juice is Asian white birch sap, tapped in spring. It is over 98 percent water with trace minerals and sugars, and Korean formulas use it in place of plain water as a hydrating base.
Rosa Damascena Flower Water plant extract: Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
Vanilla Planifolia Fruit Extract plant extract: Vanilla bean extract. It carries vanillin, the compound its scent comes from, along with polyphenols, so it contributes fragrance as well as extract.
Pimpinella Anisum (Anise) Fruit Extract plant extract: Anise seed extract. It carries the plant's aromatic compounds and is used as a conditioning extract that contributes scent.
Pyrus Communis (Pear) Fruit Extract plant extract: Pear Fruit Extract carries fruit sugars and mild fruit acids. It is used as a hydrating extract with a very light smoothing effect on the surface.
Hedera Helix (Ivy) Leaf/Stem Extract plant extract: Ivy Leaf and Stem Extract carries saponins, plant compounds that foam slightly in water. It is used in body and eye formulas for the look of puffiness.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
Simmondsia Chinensis (Jojoba) Seed Oil emollient: Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
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.
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 this lotion AM and/or PM, as the lightweight moisturizer step, after serum. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.

Worth knowing

Patch test this lotion on a small area and wait a day before using it more widely, especially with Snail Secretion Filtrate on the list.
Introduce this lotion on its own for the first week, so anything your skin does is traceable to the Snail Secretion Filtrate rather than to three changes at once.
