Key actives
4Niacinamide
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.
9Hydrolyzed Sponge
Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant.
20Adenosine
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.
22Madecassoside
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.

How is this serum used in a routine?
Apply a few drops to cleansed skin and pat in gently before moisturiser. It works as a treatment step layered under moisturiser.
Is this the same formula sold in Korea?
Yes. MEDIHEAL's Madecassoside Pore Repair Serum 40ml is sold here as the Korean-market formula, the same version carried in Korea, with intact Korean-market packaging and batch coding, not a US-shelf reformulation.
Who is this serum suited for?
Normal skin, Dry or dehydrated skin are the best fit for this serum. Patch test on the inner arm before first full use, as with any new skincare product.

Ingredient list read from medihealshop.com on 30 August 2026.
47 of 47 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hydrolyzed Sponge active
- Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant.
- Diglycerin humectant
- Diglycerin is two glycerin units joined together. It holds water like glycerin but feels less tacky, so it is used where a formula needs hydration without drag.
- 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.
- Ammonium Acryloyldimethyltaurate/Vp Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
35 more explained
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- 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.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- 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.
- 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.
- 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.
- 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.
- Trisodium Ethylenediamine Disuccinate chelator
- A readily biodegradable chelator used in place of EDTA. It ties up trace metal ions in the water so they cannot spoil the formula.
- 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.
- 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.
- 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.
- Iris Florentina Root Extract plant extract
- Iris Florentina Root Extract, or orris root, is a long-standing perfumery and skincare ingredient. It is used as a conditioning extract with a soft, powdery scent.
- 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.
- Cucumis Melo (melon) Fruit Extract plant extract
- Melon Fruit Extract carries fruit sugars and a natural antioxidant enzyme system. It is used as a light hydrating extract.
- Pogostemon Cablin Oil fragrance component
- Patchouli oil, steam distilled from the leaves. It is one of the heaviest, longest lasting aromatic oils and is used to scent a formula and to hold lighter notes in place.
- 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.
- 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.
- Ficus Carica (fig) Fruit Extract plant extract
- Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
- Cyperus Rotundus Root Extract plant extract
- Nut grass root extract, a long used South Asian botanical. The tuber carries aromatic sesquiterpenes and flavonoids and is used as a conditioning extract.
- Artemisia Vulgaris Oil fragrance component
- Mugwort essential oil. It scents a formula as well as conditioning it, and essential oils are the class most likely to bother reactive skin.
- Rosmarinus Officinalis (rosemary) Leaf Oil fragrance component
- Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
- 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.
- Diospyros Kaki Leaf Extract plant extract
- Diospyros Kaki is the persimmon tree. Its leaf extract carries tannins and vitamin C and is used as an antioxidant extract.
- 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.
- Vitis Vinifera (grape) Fruit Extract plant extract
- Grape Fruit Extract carries polyphenols and fruit acids. It is used as an antioxidant plant extract.
- Carthamus Tinctorius (safflower) Flower Extract plant extract
- Safflower Flower Extract is a traditional East Asian dye and skincare plant. It is used as a conditioning antioxidant extract and can tint a formula.
- Coffea Arabica (coffee) Seed Extract plant extract
- Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
- Polygonum Cuspidatum Root Extract plant extract
- Polygonum Cuspidatum is Japanese knotweed, the main commercial source of resveratrol. Its root extract is used as an antioxidant plant extract.
- 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.
- Castanea Crenata Shell Extract plant extract
- Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
- Zanthoxylum Piperitum Fruit Extract plant extract
- Zanthoxylum Piperitum is Korean pepper. Its fruit extract is used as a conditioning plant extract and is often paired with pulsatilla and usnea in Korean formulas.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.

How it works
Madecassoside is named on the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Hydrolyzed Sponge and Adenosine. 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.
