How it works
The Hyper-fit Balancing Toner is a 150ml toner, used straight after cleansing, morning and evening, while the face is still damp. The active it is built around is Succinic Acid, named fifth on its own ingredient list. The same list carries Madecassoside, Tocopherol and Hydrolyzed Vegetable Protein, so the active is not the only thing on it worth naming. How much of the Succinic Acid stays on the skin, and for how long, is decided by the toner format rather than by the list alone. FEEV sells this Succinic Acid toner in Korea, and this is that version.

Key actives
5Succinic Acidactive
Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here. On this toner's own ingredient list it is named fifth.
11Madecassosideactive
Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams. It is named eleventh on this toner's list, alongside Succinic Acid.
14Biosaccharide Gum-1polysaccharide
Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel. The panel names it fourteenth on this toner's list, beside Succinic Acid.
16Hydrolyzed Vegetable Proteinprotein
Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface. The panel names it sixteenth on this toner's list, beside Succinic Acid.
22Tocopherolantioxidant
Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer. It is named twenty-second on this toner's list, alongside Succinic Acid.
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 Succinic Acid and not three changes at once.
What else is on the list besides Succinic Acid?
Madecassoside, Tocopherol and Hydrolyzed Vegetable Protein. The order they are printed in on this toner's panel is the order on the box, so you can see where Succinic Acid sits relative to them. Further down the same panel: Biosaccharide Gum-1, Camellia Sinensis Leaf Extract and Hydrolyzed Hyaluronic Acid.

19 of 23 explained
- Purified 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.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Succinic Acid active
- Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here.
- 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.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- Madecassoside active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
- Green Tea Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Biosaccharide Gum-1 polysaccharide
- Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
7 more explained
- Hydrolyzed Vegetable Protein protein
- Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface.
- Saccharide Hydrolysate humectant
- Saccharide Hydrolysate is a mixture of plant sugars broken down for use as a humectant. It holds water in the outer layer.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Maltodextrin film former
- Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
- 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.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.

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.
Worth knowing
- Patch test this toner on a small area and wait a day before using it more widely, especially with Succinic Acid on the list.
- Introduce this toner on its own for the first week, so anything your skin does is traceable to the Succinic Acid rather than to three changes at once.
