## Key benefits

- Four forms of hyaluronic acid on one panel, not a single token inclusion
- Niacinamide on the same panel, the formula's active
- Allantoin on the same panel, the formula's active
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item

## How it works

The panel on this sheet mask names four forms of hyaluronic acid rather than one: Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, Hyaluronic Acid. 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, Allantoin and Sophora Angustifolia Root Extract. 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. Use it as the weekly treatment, two to three times a week, for 15 to 20 minutes, giving it a moment to settle before the next step.

## FAQ

### Is this the same formula sold in Korea, or a US version?

This is sourced for the Korean market rather than reformulated for US shelves. Numbuzin sells a separate reformulation on some US shelves, and this listing is not that version. The Korean-market batch coding and packaging travel with it, which is the detail worth checking against the box on arrival.

### 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. Niacinamide 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 sheet mask in a Korean routine does.

### 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.

### 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.
