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 Fragrance. 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, Streptococcus Thermophilus Ferment and Saccharomyces Ferment Filtrate. 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: Micrococcus Lysate, Tocopherol and Beta-Glucan.

All products with Streptococcus Thermophilus Ferment

18Saccharomyces Ferment Filtrateferment

Saccharomyces Ferment Filtrate is a brewers yeast ferment filtered clear. It supplies amino acids, B vitamins and sugars, and it is one of the ferments the Korean essence category was built on. It is named eighteenth on this toner's list, alongside Niacinamide.

All products with Saccharomyces Ferment Filtrate

27Adenosineactive

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. The panel names it twenty-seventh on this toner's list, beside Niacinamide.

All products with Adenosine

32Micrococcus Lysateferment

Micrococcus Lysate is a bacterial culture with the cells broken open. It is used as a conditioning ferment component, most often in formulas aimed at the look of sun-exposed skin. The panel names it thirty-second on this toner's list, beside Niacinamide.

1 of 3

33 of 36 explained

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.
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.
Glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
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.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
Squalane emollient: Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
Streptococcus Thermophilus Ferment ferment: Streptococcus Thermophilus Ferment is a yoghurt-culture ferment. It is used for its conditioning effect on the outer layer of skin.
Xylitol humectant: Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
Sodium Hyaluronate humectant: Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
Pyrus Malus (Apple) Juice plant extract: Apple juice used in place of part of the water in a formula. It carries sugars and malic acid and is a dilute base ingredient rather than an active.
Theobroma Cacao (Cocoa) Extract plant extract: Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
Vincetoxicum Atratum Extract plant extract: Baekmi, a traditional Korean herbal root extract. It is used as a conditioning plant extract, usually beside other Korean herbal ingredients.

21 more explained

Pyrus Communis (Pear) Fruit Extract plant extract: Pear Fruit Extract carries fruit sugars and mild fruit acids. It is used as a hydrating extract with a very light smoothing effect on the surface.
Althaea Rosea Flower Extract plant extract: Althaea Rosea is hollyhock, a mallow relative rich in mucilage. Its flower extract hydrates and leaves a cushioned, slippery feel.
Aloe Barbadensis Leaf Extract plant extract: Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
Saccharomyces Ferment Filtrate ferment: Saccharomyces Ferment Filtrate is a brewers yeast ferment filtered clear. It supplies amino acids, B vitamins and sugars, and it is one of the ferments the Korean essence category was built on.
Linum Usitatissimum (Linseed) Seed Extract plant extract: Flaxseed extract. Flaxseed swells into a mucilage in water, so the extract hydrates and leaves a cushioned, slippery feel.
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.
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.
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.
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.
Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener: This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
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.
Ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
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.
Sodium Polyacrylate thickener: Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
Sodium Phytate chelator: Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
Dextrin thickener: Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
Beta-Glucan polysaccharide: 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.
Micrococcus Lysate ferment: Micrococcus Lysate is a bacterial culture with the cells broken open. It is used as a conditioning ferment component, most often in formulas aimed at the look of sun-exposed skin.
Ectoin humectant: Ectoin is a small molecule that microbes in salt flats and hot springs make to survive extreme conditions. In skincare it holds water tightly around itself, which is why it appears in formulas aimed at reactive, easily dehydrated skin.
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.
Fragrance fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.

How it works

The Aqua Serum Toner is a 200ml 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, Streptococcus Thermophilus Ferment and Saccharomyces Ferment Filtrate, 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. JUNGSAEMMOOL sells this Niacinamide toner in Korea, and this is that version.

How to use

Apply a few drops to cleansed skin and pat in gently before moisturiser.

Worth knowing

Patch test this toner on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
This list names Fragrance, so skip it if fragrance components are something you avoid.
