Key actives
7Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this eye cream's own ingredient list it is named seventh.
27Allantoinactive
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 twenty-seventh on this eye cream's list, alongside Niacinamide.
38Adenosineactive
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 thirty-eighth on this eye cream's list, alongside Niacinamide.
58Acetyl Hexapeptide-8peptide
Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable. The panel names it fifty-eighth on this eye cream's list, beside Niacinamide.
59sh-Oligopeptide-2peptide
sh-Oligopeptide-2 is a second fermentation-produced peptide, used alongside sh-oligopeptide-1 for the look of firmness. It is named fifty-ninth on this eye cream's list, alongside Niacinamide.

Isntree TW-Real Eye Cream 30ml
Where does this eye cream go in my routine?
After serum and before moisturizer, morning and evening. Anything thinner than an eye cream 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 Niacinamide and not three changes at once.
What else is on the list besides Niacinamide?
Allantoin, Adenosine and Acetyl Hexapeptide-8. The order they are printed in on this eye cream's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: sh-Oligopeptide-2, sh-Polypeptide-1 and sh-Oligopeptide-1.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

62 of 62 explained
- Bifida Ferment Lysate ferment
- Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
- 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.
- 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.
- 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.
- Squalane emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- Hydrogenated Polydecene emollient
- Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
- 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.
- 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.
- Pentaerythrityl Tetraethylhexanoate emollient
- Pentaerythrityl Tetraethylhexanoate is a light ester emollient that gives a dry, silky finish and disperses pigment evenly.
- Arachidyl Alcohol fatty alcohol
- Arachidyl Alcohol is a long-chain fatty alcohol used as a thickener and emollient, usually alongside behenyl alcohol.
- 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.
- 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.
50 more explained
- 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.
- C12-16 Alcohols fatty alcohol
- C12-16 Alcohols is a blend of medium-chain fatty alcohols used to thicken and stabilise an emulsion.
- Polyglyceryl-2 Stearate emulsifier
- Polyglyceryl-2 Stearate is a plant-derived emulsifier used to stabilise creams with a light finish.
- Behenyl Alcohol fatty alcohol
- Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- Polysorbate 60 emulsifier
- Polysorbate 60 is a water-loving emulsifier used with a fatty co-emulsifier to build stable lotions and creams.
- 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.
- 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.
- 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.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- Stearyl Alcohol fatty alcohol
- Stearyl Alcohol is a solid fatty alcohol used to thicken and stabilise creams. Like the other fatty alcohols it is an emollient, not a solvent.
- Dimethicone/Vinyl Dimethicone Crosspolymer silicone
- This is a silicone elastomer, a soft springy gel. It fills the look of fine texture and gives the velvety, blurred finish of a primer.
- Arachidyl Glucoside emulsifier
- Arachidyl Glucoside is a sugar-derived co-emulsifier, usually supplied with arachidyl and behenyl alcohols as a plant-based cream base.
- 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.
- 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.
- 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.
- Illicium Verum (Anise) Fruit Extract plant extract
- Star Anise Fruit Extract carries aromatic plant compounds. It is used as a conditioning extract and contributes scent.
- Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is a pre-neutralised polymer thickener that gels on contact with water and stabilises an emulsion without heat.
- Mangifera Indica (Mango) Seed Butter emollient
- Mango seed butter, pressed from the kernel. It is a soft solid at room temperature and melts on skin, so it is used where a formula needs richness without the waxiness of shea.
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
- Isohexadecane emollient
- Isohexadecane is a branched hydrocarbon emollient that spreads easily and leaves a dry finish. It is often paired with a thickener to build a gel-cream.
- Persea Gratissima (Avocado) Oil emollient
- Avocado oil, rich in oleic acid and plant sterols. It is one of the heavier plant oils, which suits dry skin and cleansing balms.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Scutellaria Baicalensis Root Extract plant extract
- Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
- 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.
- Polysorbate 80 emulsifier
- Polysorbate 80 is an emulsifier and solubiliser used to keep oils, fragrance and oil-soluble actives dissolved in water.
- 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.
- Hydrogenated Vegetable Oil occlusive
- Plant oil hardened by hydrogenation. It behaves as a soft solid, so it gives balms and sticks their body and slows water loss from the surface.
- 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.
- 3-O-Ethyl Ascorbic Acid antioxidant
- 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
- Sorbitan Oleate emulsifier
- Sorbitan Oleate is an emulsifier for water-in-oil formulas. It keeps a rich cream or a cleansing oil from separating.
- Glucose humectant
- Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
- 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.
- Daucus Carota Sativa (Carrot) Root Extract plant extract
- Carrot Root Extract carries carotenoids, which give it a strong orange colour. It is used as an antioxidant extract and can tint a formula.
- 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.
- Sodium Phosphate pH adjuster
- Sodium Phosphate is a buffer salt. It holds a formula at a steady pH so its actives stay in the form they work in.
- 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.
- Deoxyphytantriyl Palmitamide MEA barrier lipid
- A synthetic ceramide-like lipid. It sits in the spaces between skin cells the way skin's own ceramides do and helps hold water in.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- 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.
- Polysorbate 20 emulsifier
- Polysorbate 20 is a solubiliser: it dissolves small amounts of oil or fragrance into a watery formula so nothing separates or floats.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Lecithin emulsifier
- Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
- 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.
- Acetyl Hexapeptide-8 peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
- sh-Oligopeptide-2 peptide
- sh-Oligopeptide-2 is a second fermentation-produced peptide, used alongside sh-oligopeptide-1 for the look of firmness.
- sh-Polypeptide-1 peptide
- sh-Polypeptide-1 is a longer fermentation-produced peptide. It is used in formulas built around the look of resilience and recovery.
- Astaxanthin antioxidant
- Astaxanthin is a deep red antioxidant from microalgae, the pigment that makes salmon pink. It is oil soluble, colours a formula noticeably, and is used as an antioxidant.
- sh-Oligopeptide-1 peptide
- sh-Oligopeptide-1 is a peptide made by yeast fermentation rather than synthesis, which is what the sh prefix records. It is used for the look of firmness and skin recovery after irritation.

How it works
The TW-Real Eye Cream is a 30ml eye cream, used after serum and before moisturizer, morning and evening. The active it is built around is Niacinamide, named seventh on its own ingredient list. The same list carries Allantoin, Adenosine and Acetyl Hexapeptide-8, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the eye cream format rather than by the list alone. Isntree sells this Niacinamide eye cream in Korea, and this is that version.
How to use
- Use the TW-Real Eye Cream after serum and before moisturizer, morning and evening.
- A grain of rice per eye, tapped along the orbital bone with the ring finger rather than dragged toward the lashes.
- Serum first, this second, moisturizer over the top and out to the edges of the eye area.
- Twice a day. Do not apply it right up to the lash line; the product travels on its own as the day goes on.
Worth knowing
- Patch test this eye cream on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Introduce this eye cream on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.
