## How it works

The AC Collection Acne Patch is a patch, used apply a patch from it to clean, dry skin at the end of the evening routine. The plant extract it is built around is Centella Asiatica Extract, named sixth on its own ingredient list. The same list carries Mineral Oil, so the plant extract is not the only thing on it worth naming. How much of the Centella Asiatica Extract stays on the skin, and for how long, is decided by the patch format rather than by the list alone. COSRX sells this Centella Asiatica Extract patch in Korea, and this is that version.

## How to use

1. Press a patch from the AC Collection Acne Patch onto clean, dry skin at the end of the evening routine.
2. Push it down from the middle outward until the edges sit flat, then leave it in place overnight.
3. Nothing goes over it, and it holds best on bare skin, so let every leave-on layer absorb first.
4. One patch per spot per session. Do not press a fresh patch onto damp skin or over a cream; it will lift within the hour.

## FAQ

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

Apply a patch from it to clean, dry skin at the end of the evening routine. Toner goes on before it, and the rest of the routine goes on after you take the patch off. 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 Centella Asiatica Extract and not three changes at once.

### What else is on the list besides Centella Asiatica Extract?

Mineral Oil. The order they are printed in on this patch's panel is the order on the box, so you can see where Centella Asiatica Extract sits relative to them. Centella Asiatica Extract itself is named sixth on it.
