It still works great to extract the oils from the pimple, especially when it's ready to pop. But if you've got one lingering around on its early days, it's not super effective. I have sensitive skin and am terribly allergic to band-aids so I'm very happy that I don't have any reactions to this product given how sticky it is. The three sizes are great but I just wish there were more of the medium sizes available.

This is effective and easy to use.

I really wish that COSRX released this product when I was in high school. This product really helped my acne to heal up quicker and protects the troubled spots well. If you have a habit of picking at your pimples/acne, this will help you from doing too much damage to your skin as it covers the troubled spots from outside contaminants. Give this a shot and you will not be disappointed.

Really helps calm and ease the breakout while doing its job overnight! By morning it’s calm down my breakout really well.

They stick well. Whilst they do not appear to have any medicinal impact, they do cover the zit effectively acting like a bandaid to stop me from touching the zit allowing it to heal. The smallest size is a bit too small for my use, but the medium size is perfect.
