## How it works

A hydrocolloid patch is a physical cover rather than a formula: it sticks to a clean dry surface, absorbs what a weeping spot gives off, and keeps your fingers off it. That last part is most of the value, since picking is what turns a two day spot into a two week mark. Being thin, these sit flat enough to wear under makeup rather than only overnight, which is what the mixed sizes are for. That is the difference from a spot cream, which is the better choice for a closed bump because a patch has nothing to hold onto and nothing to absorb. What you can judge is whether the patch has gone cloudy when you take it off.

## How to use

1. Cleanse and dry the area completely, since a patch will not hold onto damp or creamed skin.
2. Pick the smallest patch that covers the spot with a little margin around it and press the edges down.
3. Leave it in place for at least six hours, or overnight, rather than checking it every hour.
4. Do not put a patch over moisturizer or sunscreen, because it will lift within minutes and do nothing at all.

## FAQ

### What does a hydrocolloid patch do?

It covers a spot, absorbs what an open one gives off, and keeps your fingers away from it. That last part matters most, since picking is what turns a short lived spot into a lasting mark. You judge it on whether the patch has gone cloudy by the time you take it off.

### Where does it go in my routine?

Onto clean dry skin with nothing else on the area. Do the rest of your routine around it, avoiding the spot itself, since cream or sunscreen under a patch stops it sticking. Most people apply one at the end of the evening and take it off in the morning.

### Can I wear one under makeup?

These are thin enough for that, which is what the smaller sizes are for. Apply it to bare clean skin first, then work makeup around and lightly over the edges. Do not apply moisturizer under it, because the patch will lift within minutes and be useless for the day.

### How long should I leave one on?

At least six hours, and overnight is easiest. Taking it off early to check gives you a patch that no longer sticks and a spot you are now touching. If it goes cloudy and lifts at an edge before six hours, replace it with a fresh one rather than pressing it back.

### Is this the Korean-market formula?

Yes. This is the Original Korean Formula sheet, the same one sold on Korean shelves.
