## How it works

Dipotassium Glycyrrhizate is named on the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Pueraria Lobata Root Extract and Pinus Palustris Leaf 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 serum step, AM and PM, after toner and before moisturizer, 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 the exact Korean-market formula, not a US-shelf reformulation. molvany 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 serum 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 Dipotassium Glycyrrhizate do in this formula?

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. It is named on this product's own ingredient panel.
