How it works
Azelaic acid is a slow, steady active rather than a fast one, and in a cream base it can be worn daily instead of a few evenings a week. This one carries azelaic acid near the front of its list, with panthenol and madecassoside behind it to keep the base comfortable. It goes on after toner as the treatment step, and a plain moisturizer can go over the top of it. Skin that looks flushed across the cheeks and nose and breaks out in the same places is the case it fits. Start in the evening a few times a week, then move to twice a day once skin has settled into it.
Key benefits
- Azelaic acid is the second ingredient on the list
- The number in the name is the brand's stated strength; the list itself declares no percentage, so we claim none
- Madecassoside, licorice root extract and zinc PCA calm the look of redness
- Alpha-arbutin and niacinamide support a more even tone where marks linger
Key actives
COSRX Azelaic Acid 10 B5 Redness Soothing Cream
What is the Azelaic Acid 10 B5 Redness Soothing Cream meant to target?
Azelaic acid sits second on this jar's own ingredient list, right after water, with panthenol, madecassoside, niacinamide, and alpha-arbutin all appearing further down. The list itself does not carry a declared percentage for azelaic acid, so any number in the product name is not something we repeat as a verified figure here. What the list does confirm is a redness- and tone-focused formula built around azelaic acid supported by soothing plant extracts.
Is this cream appropriate for redness-prone or reactive skin?
Madecassoside and licorice root extract both appear on the list, ingredients commonly chosen to comfort reactive or redness-prone skin, alongside zinc PCA and a run of hyaluronate forms for hydration. Fragrance, essential oil, denatured alcohol, paraben, sulfate surfactants, mineral oil, and added colourant are all absent. Azelaic acid can still cause mild tingling on first use for some people, so starting at a lower frequency is a reasonable approach.
How soon will redness or uneven tone improve with this cream?
Azelaic acid and alpha-arbutin both work on the look of tone gradually, generally over several weeks of consistent use rather than after a handful of applications. The soothing ingredients further down the list, like madecassoside and panthenol, offer more immediate comfort on application while the slower tone-focused work continues underneath. This is a cream to build a routine around rather than reach for occasionally.
Can I use this alongside a brightening serum or retinoid?
Because this cream carries an active acid, pairing it with a separate brightening serum or a retinoid used at a different time of day is the more cautious approach, since layering multiple actives at once raises the chance of irritation. The label's own suggested routine starts with PM-only use before moving to twice daily as skin adjusts. Space out other actives and watch how skin responds before combining everything at once.
How can I confirm this jar is genuine Korean-market COSRX stock?
This particular jar's barcode does not check out as a genuine Korean-market code, so we do not point anyone to that number as proof. COSRX's own verification system is the reliable route: find the checker on cosrx.com and enter the batch number and expiration date printed on your jar itself. That information comes straight from your unit rather than from any number we could supply.

40 of 40 explained
- AQUA/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.
- AZELAIC ACID active
- Azelaic Acid is a grain-derived acid used for the look of redness and uneven tone. It is not an exfoliant in the AHA sense and is usually formulated at 10 percent or below in cosmetics.
- 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.
- COCO-CAPRYLATE/CAPRATE emollient
- Coco-Caprylate/Caprate is a coconut-derived ester used as a light, dry emollient in place of silicone. It spreads far and leaves a soft finish.
- 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.
- 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.
- C12-15 ALKYL BENZOATE emollient
- C12-15 Alkyl Benzoate is a light ester emollient and solvent. It gives a silky finish, dissolves pigments and UV filters, and mildly discourages microbial growth.
- SORBITAN STEARATE emulsifier
- Sorbitan Stearate is a mild emulsifier and thickener used to hold oil and water together in creams.
- 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.
- 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.
- 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.
28 more explained
- 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.
- 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.
- 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.
- 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.
- SUCROSE COCOATE emulsifier
- Sucrose Cocoate is table sugar joined to coconut fatty acids. It is a very mild emulsifier and cleanser that also holds water, so it turns up in gentle cleansers and toners.
- SODIUM POLYACRYLOYLDIMETHYL TAURATE thickener
- Sodium Polyacryloyldimethyl Taurate is a polymer thickener that holds a gel stable even with a lot of salt or acid in the formula.
- SODIUM METAPHOSPHATE chelator
- A phosphate salt that ties up metal ions in water. It also stops the calcium and magnesium in hard water from flattening a cleanser foam.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- DIPOTASSIUM GLYCYRRHIZATE active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- ZINC PCA active
- Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time.
- GLUCONOLACTONE exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- ALPHA-ARBUTIN active
- Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH.
- 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.
- 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.
- 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.
- 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 CROSSPOLYMER humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- 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.
- 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.
- 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.
- SODIUM ACETYLATED HYALURONATE humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
