Key actives
1Actinidia Chinensis (Kiwi) Fruit Extractplant extract
Kiwi fruit extract, high in vitamin C and fruit acids. It is used as a conditioning antioxidant extract. The panel names it first on this exfoliating toner's list, beside Niacinamide.
6Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this exfoliating toner's own ingredient list it is named sixth.
11Glycolic Acidexfoliant
It loosens the bonds between dead surface cells and is used for the look of dullness and rough texture. It is named eleventh on this exfoliating toner's list, alongside Niacinamide.
12Allantoinactive
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. The panel names it twelfth on this exfoliating toner's list, beside Niacinamide.
14Adenosineactive
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 fourteenth on this exfoliating toner's list, alongside Niacinamide.

Where does this exfoliating toner go in my routine?
In the evening, after cleansing, on dry skin rather than damp. Anything thinner than an exfoliating 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.
What else is on the list besides Niacinamide?
Allantoin, Adenosine and Glycolic Acid. The order they are printed in on this exfoliating toner's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Actinidia Chinensis (Kiwi) Fruit Extract, Hylocereus Undatus Fruit Extract and Ethyl Hexanediol.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from inkeedecoder.com on 26 August 2026.
16 of 16 explained
- Actinidia Chinensis (Kiwi) Fruit Extract plant extract
- Kiwi fruit extract, high in vitamin C and fruit acids. It is used as a conditioning antioxidant extract.
- Hylocereus Undatus Fruit Extract plant extract
- Dragon fruit extract, from a night-flowering cactus. It carries betalains and water-holding sugars and is used as a hydrating extract.
- Salix Alba (Willow) Bark Water plant extract
- Willow bark distillate. It is much more dilute than willow bark extract and carries little of the salicin the extract is used for.
- Pyrus Malus (Apple) Fruit Water plant extract
- Apple distillate used in place of plain water. Like every fruit water it is far more dilute than the extract of the same fruit.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Ethyl Hexanediol humectant
- Ethyl Hexanediol is a glycol that hydrates and makes a formula less hospitable to microbes, the same double role 1,2-hexanediol plays.
- Sodium Lactate humectant
- Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- Glycolic Acid exfoliant
- Glycolic Acid is the smallest AHA, which is why it is also the most penetrating and the most likely to sting. It loosens the bonds between dead surface cells and is used for the look of dullness and rough texture.
- Allantoin active
- 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.
4 more explained
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Adenosine active
- 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.
- Betaine Salicylate exfoliant
- Betaine Salicylate is a gentler salicylic derivative. Korean formulas use it at around 2 to 4 percent, which is roughly comparable to a low-strength salicylic acid, and it is easier on the skin barrier.
- Ascorbyl Glucoside antioxidant
- Ascorbyl Glucoside is vitamin C bound to glucose, which keeps it stable until enzymes in skin release it. It is a mild, slow-release route to a vitamin C formula.

How it works
The Refresh ABC Daily Toner (AHA BHA Vitamin C) is a 50ml exfoliating toner, used in the evening, after cleansing, on dry skin rather than damp. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Allantoin, Adenosine and Glycolic 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 exfoliating toner format rather than by the list alone. COSRX sells this Niacinamide exfoliating toner in Korea, and this is that version.
How to use
- Use the Refresh ABC Daily Toner (AHA BHA Vitamin C) in the evening, after cleansing, on dry skin rather than damp.
- Sweep it over the face with a cotton pad or fingertips, keeping clear of the eyelids and the corners of the mouth.
- Wait a minute, then carry on with a hydrating layer and your moisturizer the same evening.
- Start at two or three evenings a week and build from there. Do not use it in the same routine as another exfoliating acid or a retinoid.
Worth knowing
- Patch test this exfoliating toner on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Betaine Salicylate and Glycolic Acid on this list makes this exfoliating toner an exfoliating step, so do not stack it with another one on the same night.

What professionals say
What professionals say
What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
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.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic As we age, the glue that holds our skin cells together becomes denser, which slows down the natural cell turnover process.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic
1 more professional perspective
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.
