How it works
NINELESS B-Boost 1% Kojic Acid Toner is a toner sold in NINELESS's Korean-market packaging and format. Niacinamide is listed 5th of 21 ingredients, an early, prominent position on the list, carrying this formula's brightening and tone-evening work. Kojic Acid is listed 6th of 21 ingredients, an early, prominent position on the list, carrying this formula's brightening and tone-evening work. Adenosine is listed 11th of 21 ingredients, a supporting position further down the list, adding the conditioning, moisture-supporting quality this formula relies on. Sodium Hyaluronate and Dipotassium Glycyrrhizate are also present on the list, in a supporting amount alongside the ingredients above. It takes the step right after cleansing of a Korean-style layering routine, used after cleansing, am and/or pm.
Key benefits
- Niacinamide sits early in the 21-ingredient list, a tone-evening ingredient that works on visible unevenness and surface texture
- Kojic Acid sits early in the 21-ingredient list, a brightening acid derived from fermentation, used in this formula for an evener finish
- Adenosine sits mid-way through the 21-ingredient list, a smoothing ingredient long used in Korean formulas to soften the look of fine lines
- Sodium Hyaluronate sits in the back third of the 21-ingredient list, a salt form of hyaluronic acid that draws and holds water at the skin's surface
- Formulated as a toner from NINELESS, sized for regular use in a routine
- Comes in a 200ml format, sized for the toning step right after cleansing

What is NINELESS B-Boost 1% Kojic Acid Toner for?
It is a toner in NINELESS's Korean-market lineup, built around Niacinamide (5th of 21 ingredients). After cleansing, AM and/or PM. Pat onto the face with hands or a cotton pad before serum. What ships is the same Korean-market formula and packaging NINELESS sells at home, not a US-reformulated version.
Where does this go in a routine, and how do I use it?
After cleansing, AM and/or PM. Pat onto the face with hands or a cotton pad before serum. It takes the step right after cleansing of a Korean-style layering routine. Give it a minute to settle before adding the next product on top.
Does B-Boost 1% Kojic Acid Toner contain Niacinamide?
Yes, Niacinamide is listed 5th of 21 ingredients on the panel, an early, prominent position. It is a tone- and texture-focused brightening active in this formula, working alongside the other ingredients on the panel.
Is this the authentic Korean-market version, not a US retail reformulation?
Yes. What we ship is NINELESS's Korean-market formula and packaging, sourced for the Korean market rather than a US-facing reformulation. The intact Korean barcode and batch code on the box are part of that proof.
Who is this product best suited for?
Normal, Combination, Dull or uneven-tone skin and Dry skin types are the best fit, based on the actives on its ingredient panel. Patch test first, as with any new addition to a routine.

20 of 20 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.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- 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.
- Kojic Acid active
- Kojic Acid comes from the fermentation of rice by Aspergillus, the mould used to make sake. It is used in formulas addressed to the look of uneven tone, and it darkens in air.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Polyglyceryl-10 Myristate emulsifier
- Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
- 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.
- 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.
8 more explained
- 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.
- 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.
- 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.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Lactobacillus Ferment ferment
- Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
- Bifida Ferment Lysate ferment
- Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
- Lactococcus Ferment ferment
- A ferment of lactococcus, one of the lactic acid bacteria used to make cheese and buttermilk. It supplies peptides and organic acids and is used as a conditioning ferment.
- 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.

How to use
- Use the B-Boost 1% Kojic Acid Toner straight after cleansing, morning and evening, while the face is still damp.
- Apply a moderate amount to the face using a cotton pad or your hands.
- It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
- Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.
Worth knowing
- Patch test on the inner arm 24 hours before adding this to your face or scalp, as with any new product.
- Introduce it gradually alongside the rest of your routine rather than adding several new actives at once.
