## Key benefits

- 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

## 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.

## How to use

1. Apply within a minute of cleansing while the face is still wet, so the water goes in rather than off.
2. Pour a generous amount into damp palms and press it over the face and down the neck.
3. Add a second layer on a tight feeling day rather than reaching for a heavier cream instead.
4. Do not wipe it off with a dry cotton pad, since the cotton takes a share of the dose and gives nothing back.

## FAQ

### 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.
