The product is very good. I applied it on 2-3 pimples and left it on for about 8 hours (I have no idea how long you're supposed to leave it on normally, I just do what I've seen on the internet) and the pimples disappeared. One that was a bit bigger didn't completely go away but it cleared up a lot. Overall, they are easy to apply, they stay on well (I had one on my cheek right next to my mouth, I laughed really hard and it was still there!) and they don't irritate the skin.
