How it works
The panel on this toner names five forms of hyaluronic acid rather than one: Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Hydrolyzed Sodium Hyaluronate. 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. On this panel it sits alongside Niacinamide, Gluconolactone and Betaine Salicylate. 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.
Key benefits
- Five forms of hyaluronic acid on one panel, not a single token inclusion
- Niacinamide on the same panel, the formula's active
- Gluconolactone on the same panel, the formula's exfoliant
- 200 ml to a unit
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item
Inside the formula
Inside the formula
Where does this formula come from?
It comes from the Korean-market catalog rather than a US-shelf reformulation, and the packaging carries the same Korean-market batch coding a shopper would find on the box in Korea. That sourcing is checked on this row before the page is written, not assumed from the product name. It is the detail worth checking against the box on arrival.
Can I use this alongside other actives in my routine?
Yes. Glycerin is the lead active here, and it is formulated to sit alongside the rest of a routine rather than replace it. Introduce any new step on its own for the first week or two before adding it next to another strong active, so it is easy to tell which product is responsible for any change. Once it is settled into the routine, it layers the way any other toner in a Korean routine does.
How do I know this is authentic and not a US-reformulated version?
Check the box against the listing: an authentic Korean-market SKU carries Korean-primary packaging and an intact Korean-market batch code, not a US-only relabel. Numbuzin's Korean-market formulas are sourced specifically to preserve that, rather than substituted for the US-shelf version some retailers carry under the same name.
What does Sodium Hyaluronate do in this formula?
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. It is named on this product's own ingredient panel.
What does Niacinamide do in this formula?
Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

Ingredient list read from incidecoder.com on 10 September 2026.
27 of 33 explained
- 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.
- Methylpropanediol humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- 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.
- Sorbitol humectant
- Sorbitol is a sugar alcohol used as a humectant. It hydrates like glycerin with a smoother, less sticky finish, and it adds a little body to watery textures.
- 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.
- 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.
- Hydroxyethyl Urea humectant
- Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- Sodium Polystyrene Sulfonate film former
- A water soluble sulfonated polymer used as a film former and a stabiliser. It carries a strong negative charge, which is what keeps other charged ingredients evenly dispersed.
- Hydroxyethyl Cellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- 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.
15 more explained
- 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.
- Polyquaternium-51 film former
- Polyquaternium-51 is a polymer, sometimes sold as Lipidure, built on the same phosphorylcholine structure as a cell membrane. It holds water in a film on the surface and gives a distinctive soft, dry finish.
- 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.
- Papaya Fruit Extract plant extract
- Papaya fruit extract. The fruit is where the enzyme papain comes from, and the extract is used both as a conditioning extract and in gentle enzyme formulas.
- 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.
- 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.
- Centella Asiatica Extract plant 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.
- 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.
- 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.
- 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.
- Matricaria Flower Extract plant extract
- Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
- Rosemary Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- 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.
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.

How to use
- Apply within a minute of cleansing while the face is still wet, so the water goes in rather than off.
- Pour a generous amount into damp palms and press it over the face and down the neck.
- Add a second layer on a tight feeling day rather than reaching for a heavier cream instead.
- Do not wipe it off with a dry cotton pad, since the cotton takes a share of the dose and gives nothing back.
Worth knowing
- Introduce it two to three nights a week at first and watch how skin responds before using it nightly.
- Layer sunscreen the following morning, since any exfoliating step raises how visible the sun's effects can be.
