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.
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.
How do I know this is the authentic Korean-market version of the Madeca Azelaic Acid 10+ Calming Serum 30ml?
Centellian24 publishes no verification route of its own for this product, so ignore any third party site that claims to run one for it. Match the batch code on the box against the code printed on the unit itself, since the two are stamped separately and should agree.

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.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
