## How it works

The Seoul 1988 Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named seventh on its own ingredient list. The same list carries Adenosine, Retinal and Bakuchiol, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the serum format rather than by the list alone. K-Secret sells this Niacinamide serum in Korea, and this is that version.

## How to use

1. After toner, AM and/or PM. Press or smooth over the face and let it settle before the next step.

## 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 Niacinamide and not three changes at once.

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

Adenosine, Retinal and Bakuchiol. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: sh-Oligopeptide-1, sh-Oligopeptide-2 and Tocopherol.
