Key actives
14Cholesterol
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.
15Palmitic Acid
Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
19Hydroxypropyl Bispalmitamide Mea
A synthetic ceramide analogue, built to the same shape as a natural ceramide from palmitic acid. It is used as one of the lipids in a barrier style formula.
27Adenosine
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.

How do I use this toner?
Pat or sweep onto clean skin right after cleansing, morning and night, before serum or moisturizer, to prep the skin for what follows.
Do I need a separate essence if I use this?
A toner and an essence can both sit in the same slot; use one or layer both, thinner formula first, based on how much hydration your skin wants that day.

43 of 48 explained
- Water / Aqua / Eau 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.
- 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.
- 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.
- 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.
- Pentaerythrityl Tetraethylhexanoate emollient
- Pentaerythrityl Tetraethylhexanoate is a light ester emollient that gives a dry, silky finish and disperses pigment evenly.
- 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.
- 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.
- 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.
- 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.
31 more explained
- 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.
- 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.
- 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.
- Synthetic Fluorphlogopite colorant
- Synthetic mica, grown rather than mined, which makes it purer and more transparent than the natural mineral. It scatters light and carries pearlescent pigments.
- Fragrance / Parfum fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- Hydroxypropyl Bispalmitamide Mea barrier lipid
- A synthetic ceramide analogue, built to the same shape as a natural ceramide from palmitic acid. It is used as one of the lipids in a barrier style formula.
- 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.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
- 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.
- 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.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- 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.
- 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.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
- Phenoxyethanol preservative
- Phenoxyethanol is the most widely used cosmetic preservative outside the paraben family. It keeps a water-containing formula from growing bacteria and mould, and is capped at one percent in most markets, so it always sits low on a list.
- Hippophae Rhamnoides Fruit Extract plant extract
- Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
- Hemerocallis Fulva Flower Extract plant extract
- Orange daylily flower extract, from an edible flower in Korean cooking. It is used as a conditioning floral extract.
- Glycyrrhiza Uralensis (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.
- Benzyl Benzoate fragrance component
- Benzyl Benzoate is a faintly balsamic aromatic that also acts as a fixative, holding a fragrance on skin longer. It is one of the 26 declarable fragrance components.
- Panax Ginseng Root Extract plant extract
- Ginseng Root Extract is the signature ingredient of Korean traditional skincare, carrying ginsenosides. It is used for the look of tired, dull skin, and brands often ferment it to break the ginsenosides into smaller forms.
- Tin Oxide colorant
- A white mineral used in small amounts alongside pearl pigments, where it helps them disperse and brightens the effect.
- Phellodendron Amurense Bark Extract plant extract
- Amur cork tree bark, another traditional berberine-bearing herbal ingredient. It is yellow and appears in blends aimed at the look of congested skin.
- 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.
- Myristic Acid fatty acid
- Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
- Arachidic Acid fatty acid
- Arachidic Acid is a long-chain saturated fatty acid used to thicken and stabilise a formula.
- Ganoderma Lucidum (mushroom) Extract plant extract
- Reishi mushroom extract. Like most mushroom extracts it carries beta-glucan-type polysaccharides, which hold water and leave a light film.
- Rice Ferment Filtrate (sake) ferment
- Rice Ferment Filtrate is the clear liquid from fermented rice, the same process that makes sake. It carries amino acids, sugars and organic acids and is used as a conditioning ferment.
- Citral fragrance component
- Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- 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.

How it works
Cholesterol is named on the ingredient panel on this emulsion. 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. On this panel it sits alongside Palmitic Acid, Hydroxypropyl Bispalmitamide Mea and Adenosine. Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
