## How it works

Glutathione is named on the ingredient panel on this cream. Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it. On this panel it sits alongside Niacinamide, Loquat Leaf Extract and Coptis Japonica 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. Apply it last, after toner and serum, while the layers underneath are still slightly damp.
2. Warm a small amount between the fingertips so it spreads in one pass instead of dragging.
3. Press it over the whole face rather than onto the darker patches only, since even tone needs even coverage.
4. Do not skip the morning sunscreen, since a cream doing tone work assumes that last layer is going on.

## FAQ

### 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.

### When in a routine should I use this cream?

Use it as the moisturizer step, AM and PM, as the last step of the routine. Placing a cream out of order is the most common reason a Korean routine feels like it is not working, so keep this one at its own step rather than doubling it up with a product built for a different stage. Give it a few weeks at that placement before judging the result.

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

This is the exact Korean-market formula, not a US-shelf reformulation. 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.

### What does Glutathione do in this formula?

Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting 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.
