How it works
The Medeca Acnience Spot Ampoule is a 15g ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Adenosine and Asiaticoside, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. Centellian24 sells this Niacinamide ampoule in Korea, and this is that version.
Key benefits
- Niacinamide, the active this ampoule is built around
- Dipotassium Glycyrrhizate, Adenosine, Asiaticoside and Madecassic Acid on the same list, actives
- Asiatic Acid and Allantoin further down the same list
- Gluconolactone and Yeast Ferment Extract further down the same list
- Niacinamide named sixth on the manufacturer list printed on this page
Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this ampoule's own ingredient list it is named sixth.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. The panel names it forty-sixth on this ampoule's list, beside Niacinamide.
Adenosineactive
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. The panel names it forty-seventh on this ampoule's list, beside Niacinamide.
Asiaticosideactive
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. The panel names it fifty-third on this ampoule's list, beside Niacinamide.
Madecassic Acidactive
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. It is named fifty-fourth on this ampoule's list, alongside Niacinamide.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Niacinamide and not three changes at once.
Does this ampoule contain fragrance?
Yes. The ingredient list names Citronellol, Limonene and Linalool. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this ampoule is not the one.
What else is on the list besides Niacinamide?
Dipotassium Glycyrrhizate, Adenosine and Asiaticoside. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Madecassic Acid, Asiatic Acid and Allantoin.

How to use
- Apply a few drops to clean skin after toner, morning or night as directed on the pack, and follow with moisturizer to seal it in. Ampoules are typically used as a concentrated course rather than an everyday staple.
Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- This list names Citronellol, Limonene and Linalool, so skip it if fragrance components are something you avoid.
- Gluconolactone on this list makes this ampoule an exfoliating step, so do not stack it with another one on the same night.

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.
