How it works
The Madeca Relief Toner is a 300ml toner, used straight after cleansing, morning and evening, while the face is still damp. The active it is built around is Niacinamide, named fourth on its own ingredient list. The same list carries Adenosine, Allantoin and Madecassic Acid, 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 toner format rather than by the list alone. Centellian24 sells this Niacinamide toner in Korea, and this is that version.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this toner's own ingredient list it is named fourth.
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. It is named twentieth on this toner's list, alongside Niacinamide.
Allantoinactive
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. It is named twenty-fifth on this toner's list, alongside 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 twenty-ninth on this toner's list, alongside 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. It is named thirtieth on this toner's list, alongside Niacinamide.
Where does this toner go in my routine?
Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner 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 toner contain fragrance?
Yes. The ingredient list names Limonene. It sits 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 toner is not the one.
What else is on the list besides Niacinamide?
Adenosine, Allantoin and Madecassic Acid. The order they are printed in on this toner's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Asiaticoside, Asiatic Acid and Soluble Proteoglycan.

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

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.
