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 Panthenol and not three changes at once.

Is this the Korean-market lotion or a US version?

The Korean-market one, Panthenol and all. We match this lotion 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 Panthenol?

Niacinamide, Adenosine and Madecassoside. The order they are printed in on this lotion's panel is the order on the box, so you can see where Panthenol sits relative to them. Further down the same panel: Asiaticoside, Asiatic Acid and Madecassic Acid.

How it works

The Panthenol Barrier Emulsion is a 150ml lotion, used as the last skincare step, morning and evening, over serum. The humectant it is built around is Panthenol, named third on its own ingredient list. The same list carries Niacinamide, Adenosine and Madecassoside, so the humectant is not the only thing on it worth naming. How much of the Panthenol stays on the skin, and for how long, is decided by the lotion format rather than by the list alone. This is the Original Korean Formula, the lotion COSNORI sells in Korea, Panthenol and all.

1 of 3

53 of 53 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.
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.
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.
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.
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.
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.
Macadamia Integrifolia Seed Oil emollient: Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
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.
Terminalia Ferdinandiana Fruit Extract plant extract: Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
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.
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.

41 more explained

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.
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.
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.
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.
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.
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.
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.
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.
Helianthus Annuus (Sunflower) Seed Oil emollient: Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
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.
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.
Lactobacillus/Panax Ginseng Root Ferment Filtrate ferment: Ginseng root fermented with lactobacillus and strained. Fermentation cuts the large ginsenosides into smaller forms, which is why Korean brands ferment ginseng so often.
Saccharomyces/Potato Extract Ferment Filtrate ferment: Potato extract fermented with yeast and strained. It supplies sugars and amino acids and is used as a conditioning ferment.
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.
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.
Lactobacillus/Rice Ferment ferment: Rice fermented with lactobacillus, the same bacteria behind kimchi and makgeolli. Fermentation breaks the rice starch into smaller sugars and amino acids that hold water.
Saccharomyces/Coix Lacryma-Jobi Ma-Yuen Seed Ferment Filtrate ferment: Job's tears, the yulmu of Korean grain tea, fermented with yeast and strained. It supplies sugars and amino acids and is used as a conditioning ferment.
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.
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.
Sorbitan Isostearate emulsifier: Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
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.
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.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Hydrolyzed Hyaluronic Acid humectant: Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
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.
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.
Madecassoside active: Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
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.
Ceramide AP barrier lipid: Ceramide AP is a second cosmetic ceramide, distinguished by an extra hydroxyl group. Formulas that name several ceramides are copying the mix skin actually holds rather than relying on one.
Ceramide NS barrier lipid: Ceramide NS is another of the ceramides skin makes for itself. It is used alongside NP and AP so a formula supplies a mixture rather than a single lipid.
Ceramide AS barrier lipid: Ceramide AS is a further member of the same lipid family. Its presence usually signals a formula built around a full ceramide profile rather than a single headline one.
Decyl Glucoside surfactant: Decyl Glucoside is a sugar and coconut-derived surfactant, one of the mildest cleansers available. It produces a soft, low foam and rinses without stripping.
Eucalyptus Globulus Leaf Extract plant extract: Eucalyptus leaf extract, the water-based extract rather than the essential oil. It carries tannins and flavonoids with only a trace of the aroma.
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.
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.
Asiaticoside active: Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
Asiatic Acid active: Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
Madecassic Acid active: Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
Phytosphingosine barrier lipid: Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
Ceramide EOP barrier lipid: Ceramide EOP is the ceramide with the longest tail, and in skin it acts as the rivet holding the lipid layers together. It is the third member of the standard cosmetic ceramide trio.

Worth knowing

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