Key benefits
- Azelaic acid is the third ingredient, ahead of every other active on the list
- Niacinamide is the fifth, sitting directly under the azelaic acid
- Succinic acid, gluconolactone, lactic acid and salicylic acid add a mild multi-acid layer beneath it
- Asiaticoside, madecassic acid and asiatic acid are the calming side; no whole-leaf extract is declared despite the Madeca name
- No percentage appears anywhere on the list, so the number in the product name is not verifiable from the formula

Centellian24 Madeca Azelaic Acid 10+ Calming Serum 30ml
What does the Madeca Azelaic Acid 10+ Calming Serum 30ml actually do?
It sits in the line for serum work rather than a single fast fix. Azelaic Acid is an acid associated with an even-looking tone and clearer-looking pores and Niacinamide is a tone-focused ingredient that shows up across the brand's line. This product works best as a treatment step after toner and before moisturizer rather than as a stand-alone fix.
Is this suitable for sensitive or reactive skin?
Centellian24 positions its skincare line around barrier support and comfort rather than aggressive actives, and reactive-leaning skin is the audience that positioning targets. Anyone new to an ingredient on this formula's list still does well to patch test on the inner arm first and build up frequency slowly.
How long before I notice a difference with the Madeca Azelaic Acid 10+ Calming Serum 30ml?
Surface-level changes such as texture and softness tend to show first, usually within a couple of weeks of consistent use. Anything tied to tone or firmness takes longer to become visible because it builds with repeated use rather than a single application. Results depend on keeping the step in the routine; skipping it for stretches of time slows how quickly a difference shows.
Can this be layered with the rest of a routine?
It layers easily after toner and before a moisturizer. Introducing any new treatment step one at a time, rather than several at once, makes it easier to tell what a change in the skin is actually responding to.

Ingredient list read from centellian24.com on 18 August 2026.
45 of 45 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.
- Propylene Glycol humectant
- Propylene Glycol is a small glycol used as a humectant and solvent. It hydrates and helps actives dissolve; newer formulas often swap it for propanediol, which does the same job with a lighter feel.
- 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.
- Sodium Hydroxide pH adjuster
- Sodium Hydroxide is a strong base used in traces to bring an acidic formula up to skin-friendly pH. None of it remains as itself once the formula is neutralised.
- 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.
- 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.
- Succinic Acid active
- Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here.
- 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.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- Xylitol humectant
- Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
- 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.
- 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.
33 more explained
- 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.
- 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.
- 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.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- 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.
- 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.
- Biosaccharide Gum-1 polysaccharide
- Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- Gardenia Florida Fruit Extract plant extract
- Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
- 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.
- Beta-Glucan polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- Cynanchum Atratum Extract plant extract
- Cynanchum Atratum is a root used in Korean traditional practice. Its extract is used as a conditioning plant extract in formulas for reactive skin.
- Althaea Rosea Flower Extract plant extract
- Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.
- 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.
- 4-Terpineol fragrance component
- A terpene alcohol, and the main constituent of tea tree oil. On a label it is an aromatic plant constituent rather than a functional ingredient.
- Pantothenic Acid vitamin
- Pantothenic Acid is vitamin B5, the form skin converts panthenol into. It is used as a conditioning humectant that leaves skin feeling soft rather than tight.
- 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.
- Salicylic Acid exfoliant
- Salicylic Acid is a BHA, and the only common exfoliant that is oil soluble, so it can work inside a pore rather than only on the surface. It loosens the dead cells that block pores and is used for the look of congested, oily skin.
- Aloe Barbadensis Leaf Water plant extract
- Aloe leaf water, the dilute form of aloe used in place of plain water. It carries some of the leaf polysaccharides and sugars.
- Lactic Acid exfoliant
- Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin.
- Phytic Acid chelator
- Phytic Acid comes from rice bran and other seed husks. It binds metal ions, which keeps a formula stable, and it is also used as a very mild exfoliant.
- 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.
- Anthemis Nobilis Flower Extract plant extract
- Roman chamomile flower extract. It carries flavonoids and is one of the classic plant ingredients in formulas aimed at the look of reddened skin.
- Lavandula Angustifolia (Lavender) Extract plant extract
- Lavender extract, the water-soluble fraction rather than the essential oil. It is used as a conditioning extract and carries a light lavender scent.
- Origanum Vulgare Flower/Leaf/Stem Extract plant extract
- Oregano extract from the whole plant above ground, rich in the phenols carvacrol and thymol. It is used as an antioxidant plant extract.
- Rosmarinus Officinalis (Rosemary) Extract plant extract
- Rosemary extract with the plant part unstated. Rosemary carries rosmarinic and carnosic acid, and it is also used to keep the oils in a formula from going rancid.
- Thymus Vulgaris (Thyme) Extract plant extract
- Thyme extract, carrying the phenols thymol and carvacrol. It is used as an antioxidant plant extract and resists microbes.
- 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.
- Mentha Rotundifolia Leaf Extract plant extract
- Apple mint leaf extract, a softer-scented mint than peppermint. It is used as a conditioning extract with a faint cooling character.
- Thymus Vulgaris (Thyme) Leaf Extract plant extract
- Thyme leaf extract, carrying the phenols thymol and carvacrol along with rosmarinic acid. It is used as an antioxidant herbal extract.

How it works
This serum sits in Centellian24's centella-based range, built around the ingredients printed on its own box rather than a single headline claim. Azelaic Acid is an acid associated with an even-looking tone and clearer-looking pores. Niacinamide is a tone-focused ingredient that shows up across the brand's line. Panthenol rounds out the formula as a comfort ingredient for softness. In use, it works as a treatment step after toner and before moisturizer. Give the formula a few weeks in the routine before judging it, and adjust frequency to how skin responds rather than a fixed schedule.
How to use
- Use it in the evening after toner and before moisturizer.
- A thin layer over the whole face, avoiding the eye area and any broken skin.
- Follow with a moisturizer, because an acid step goes on better under a seal.
- Start every other evening and build up. Do not use it in the same routine as a retinoid or a scrub.
Worth knowing
- New to this formula: patch-test on the inner arm and wait a day before applying it to the face.
- Discontinue use if redness, itching, or irritation develops and rinse the area with water.
