Key actives
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. On this toner's own ingredient list it is named ninth.
Beta-Glucanpolysaccharide
Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin. The panel names it fourteenth on this toner's list, beside Allantoin.
Olea Europaea (Olive) Leaf Extractplant extract
Olive leaf extract, carrying oleuropein. It is used as a plant antioxidant, and it is a different ingredient from the pressed fruit oil. It is named twelfth on this toner's list, alongside Allantoin.
Centella Asiatica Extractplant extract
Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid. It is named thirteenth on this toner's list, alongside Allantoin.
Glycyrrhiza Glabra (Licorice) Root Extractplant extract
Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives. It is named fifteenth on this toner's list, alongside Allantoin.
How to use
- Pat or sweep onto clean skin right after cleansing, morning and night, before serum or moisturizer, to prep the skin for what follows.
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 Allantoin and not three changes at once.
Does this toner contain fragrance?
Yes. The ingredient list names Citronellol and Geraniol. 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 toner is not the one.
What else is on the list besides Allantoin?
Beta-Glucan, Olea Europaea (Olive) Leaf Extract and Centella Asiatica Extract. The order they are printed in on this toner's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Glycyrrhiza Glabra (Licorice) Root Extract, Equisetum Arvense Extract and Houttuynia Cordata Extract.

How it works
The Acni Dr. 1st Control Tonic is a 130ml toner, used straight after cleansing, morning and evening, while the face is still damp. The active it is built around is Allantoin, named ninth on its own ingredient list. The same list carries Beta-Glucan, Olea Europaea (Olive) Leaf Extract and Centella Asiatica Extract, so the active is not the only thing on it worth naming. How much of the Allantoin stays on the skin, and for how long, is decided by the toner format rather than by the list alone. isoi sells this Allantoin toner in Korea, and this is that version.
Worth knowing
- Introduce once daily first if new to the formula, then move to twice daily.
