How it works
Medicube Azelaic Acid 16 Calming Serum is a serum built for the treatment step right after toner. Its ingredient list leads with Azelaic Acid, Niacinamide, and Allantoin, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Azelaic Acid does the most work here as a clarity and tone, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the Azelaic Acid 16 Calming Serum line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Key actives
Azelaic AcidClarity and tone
Azelaic Acid sits near the top of the ingredient list, where the formula puts its heaviest-weighted ingredients. It is an ingredient chosen for clarity and tone: a multitasking acid known for evening out the look of blemish-prone, redness-prone skin without the sharper feel of some other acids.
NiacinamideTone and texture
Niacinamide sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for tone and texture: a form of vitamin B3 that supports a more even-looking tone and a smoother surface texture with regular use, and layers comfortably under most other actives.
AllantoinComfort
Allantoin sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: a comfort ingredient with a long safety record, added to keep the finish gentle on skin that is dealing with dryness or mild sensitivity.
Centella Asiatica ExtractComfort
Centella Asiatica Extract sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: a cica extract long used in Korean formulation for its calming reputation, chosen here to keep the finish comfortable on skin that flares easily.
PanthenolComfort
Panthenol sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: provitamin B5, a humectant and comfort ingredient that softens the finish and helps a formula feel less drying over repeated use.
Medicube Azelaic Acid 16 Calming Serum
What does the Azelaic Acid 16 Calming Serum actually contain?
Its ingredient list is led by Azelaic Acid, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Azelaic Acid 16 Calming Serum?
Use this serum as the treatment step right after toner. To apply, smooth or press onto cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Azelaic Acid 16 Calming Serum the same formula sold in Korea, or a US version?
This Azelaic Acid 16 Calming Serum is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Azelaic Acid 16 Calming Serum with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Azelaic Acid 16 Calming Serum suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. Check the listing for the exact size in stock. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Payment and security
We accept
How to use
- Use it in the evening after toner and before moisturizer, on skin that is dry to the touch.
- Three or four drops for the face, or only over the areas that run red, pressed in rather than rubbed.
- Follow with a moisturizer every time, and wear sunscreen the next morning.
- Start at two nights a week and build up. Do not use it alongside another acid or a retinoid on the same night.
Worth knowing
- Introduce it two to three nights a week at first and watch how the skin responds before moving to nightly use.
- Pair it with a daily sunscreen step, since brightening and exfoliating actives can make skin more reactive to sun exposure.

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.
