Where does this essence go in my routine?

After toner and before serum, morning and evening, on damp skin. Anything thinner than an essence 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.

Does this essence contain fragrance?

Yes. The ingredient list names Fragrance. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this essence is not the one.

What else is on the list besides Niacinamide?

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

Key actives

5Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this essence's own ingredient list it is named fifth.

All products with Niacinamide

21Adenosineactive

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-first on this essence's list, beside Niacinamide.

All products with Adenosine

27Asiaticosideactive

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. The panel names it twenty-seventh on this essence's list, beside Niacinamide.

All products with Asiaticoside

28Madecassic Acidactive

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. It is named twenty-eighth on this essence's list, alongside Niacinamide.

All products with Madecassic Acid

31Asiatic Acidactive

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. It is named thirty-first on this essence's list, alongside Niacinamide.

1 of 3

60 of 64 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.
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.
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.
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.
Polyglyceryl-3 Methylglucose Distearate emulsifier: Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
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.
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.
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.
C9-12 Alkane solvent: A light plant-derived hydrocarbon that evaporates off skin, used in place of a volatile silicone. It carries other ingredients and then leaves.
Hydroxyacetophenone preservative booster: Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.

48 more explained

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.
Fragrance 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.
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.
Dimethiconol silicone: Dimethiconol is a high-molecular-weight silicone that leaves a longer-lasting smooth film than dimethicone. It is used for lasting slip and shine.
Polyacrylate-13 thickener: Polyacrylate-13 is a pre-neutralised thickener that gels instantly and holds an emulsion together, so a formula can be built without heat.
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.
Polyisobutene film former: Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
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.
Ethoxydiglycol solvent: Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
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.
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.
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.
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.
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.
Theobroma Cacao (Cocoa) Extract plant extract: Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
Octyldodecanol emollient: Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
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.
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.
Maltodextrin film former: Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
Portulaca Oleracea Extract plant extract: Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, reactive skin.
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.
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.
Hydrolyzed Elastin protein: Hydrolyzed Elastin is fragments of elastin, the protein that gives skin its snap back. Like collagen it cannot rebuild the real thing from the outside; it holds water and leaves a smooth film.
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.
Vitis Vinifera (Grape) Seed Extract plant extract: Grape seed extract, one of the richest plant sources of proanthocyanidins. It is a water-based antioxidant extract and is a different ingredient from grape seed oil.
Galactomyces Ferment Filtrate ferment: Galactomyces Ferment Filtrate is a yeast ferment filtered clear, the ingredient that made the Korean and Japanese essence category. It carries amino acids, vitamins and organic acids and is used for the look of dullness and rough texture.
Glyceryl Glucoside humectant: Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
Sodium DNA active: Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to.
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.
Dextrin thickener: Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
Rice Ferment Filtrate 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.
Caviar Extract protein: Caviar Extract is an extract of sturgeon roe, carrying proteins, amino acids and lipids. It is a fish-derived ingredient.
Glutathione antioxidant: Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
Lepidium Meyenii (Maca) Root Extract plant extract: Maca root extract, from a high-altitude Andean root. It carries sugars, amino acids and sterols and is used as a conditioning extract.
Propolis Extract plant extract: Propolis is the resin bees collect from tree buds and use to seal the hive. It is rich in flavonoids, carries a warm amber colour and scent, and is used for the look of dull, stressed skin. It is a bee product, so it is worth knowing about if you react to those.
Pearl Extract protein: Pearl Extract is ground pearl treated so its calcium carbonate and protein fractions disperse. It is used as a mineral-and-protein conditioning ingredient with a faint light-scattering effect.
Rose Extract plant extract: A rose extract declared by common name, with neither species nor plant part stated. Rose extracts carry polyphenols and aromatic compounds and are used as conditioning botanicals.
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.
2,3-Butanediol humectant: 2,3-Butanediol is a fermentation-derived glycol. It hydrates and, like the other longer glycols, makes a formula harder for microbes to grow in.
Arginine/Lysine Polypeptide peptide: A polypeptide built from the amino acids arginine and lysine. It holds water strongly and leaves a smoothing film.
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.
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.
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 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.
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 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.

How it works

The Madeca Youth Perfection Essence Lotion is a 100ml essence, used after toner and before serum, morning and evening, on damp skin. The active it is built around is Niacinamide, named fifth on its own ingredient list. The same list carries Adenosine, Asiaticoside and Madecassic Acid, 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 essence format rather than by the list alone. Centellian24 sells this Niacinamide essence in Korea, and this is that version.

How to use

Pat into clean, slightly damp skin after toner and before serum, morning and/or night, as a lightweight hydrating layer.

Worth knowing

Patch test this essence on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
This list names Fragrance, so skip it if fragrance components are something you avoid.
