I was curious to see what the hype is all about so I purchase one to test. And I was not disppointed. It dries out my pimple fast and was very happy I bought it. Cosrx, I would say is one of the best Korean brands I've come across with.

Works great! It makes my pimples almost disappear over night! 

Very good, the best quality hydrocolloid patches I have ever used!!

Stick it on your ugly acne and rest assured you'll wake up to a less problematic acne
