How it works
The Glutathione Toning Boosting Ampoule is a 30ml ampoule, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Glutathione, named twenty-sixth on its own ingredient list. The same list carries Niacinamide, Tranexamic Acid and Bisabolol, so the antioxidant is not the only thing on it worth naming. How much of the Glutathione stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule Centellian24 sells in Korea, Glutathione and all.

- Niacinamide, Tranexamic Acid, Bisabolol and Adenosine on the same list, actives
- Milk Exosomes and Melatonin further down the same list
- Ascorbic Acid and Tocopheryl Acetate further down the same list
- Glutathione named twenty-sixth on the manufacturer list printed on this page
- Original Korean Formula, the ampoule sold on Korean shelves
Key actives
Glutathioneantioxidant
Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it. The name on the box points at it, and it is named twenty-sixth on this ampoule's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named third on this ampoule's list, alongside Glutathione.
Tranexamic Acidactive
Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired. The panel names it tenth on this ampoule's list, beside Glutathione.
Bisabololactive
Bisabolol is the main active fraction of chamomile oil, usually supplied from candeia wood. It is used for the look of redness in formulas for reactive skin, and it helps other ingredients absorb. The panel names it eighteenth on this ampoule's list, beside Glutathione.
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 nineteenth on this ampoule's list, alongside Glutathione.
Centellian24 Glutathione Toning Boosting Ampoule 30ml
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 Glutathione and not three changes at once.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Glutathione and all. We match this ampoule to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Glutathione?
Niacinamide, Tranexamic Acid and Bisabolol. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Glutathione sits relative to them. Further down the same panel: Adenosine, Milk Exosomes and Melatonin.

Payment and security
We accept
How to use
- Use it after toner and before moisturizer, morning and evening.
- A thin layer pressed over the whole face rather than dabbed on individual marks.
- Follow it with a moisturizer, because a tone step goes on better under a seal than bare.
- Twice a day. Keep sunscreen in the morning routine instead of doing tone work without it.
Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Glutathione on the list.
- Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Glutathione rather than to three changes at once.
