## How it works

The ER Firming Serum (Retinol) is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Retinol, named eighteenth on its own ingredient list. The same list carries Niacinamide, Allantoin and Dipotassium Glycyrrhizate, so the active is not the only thing on it worth naming. How much of the Retinol stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum ilso sells in Korea, Retinol and all.

## How to use

1. Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM.

## FAQ

### Where does this serum go in my routine?

After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Retinol and not three changes at once.

### Is this the Korean-market serum or a US version?

The Korean-market one, Retinol and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.

### What else is on the list besides Retinol?

Niacinamide, Allantoin and Dipotassium Glycyrrhizate. The order they are printed in on this serum's panel is the order on the box, so you can see where Retinol sits relative to them. Further down the same panel: Adenosine, Tocopheryl Acetate and Pentaerythrityl Tetra-di-t-butyl Hydroxyhydrocinnamate.
