I've heard nothing but great things about these patches and COSRX skincare in general. I decided to give them a try, not really believing it was as great as I'd heard. I am glad I was wrong. These patches are amazing. They do what they say. I have sensitive skin, a habit of touching when I break out, and I scar easily. This patch keeps the pimple protected from my wandering hands and actually does draw out the pus. I had a small pimple pop up a few days ago on my forehead, popped a patched on, and it was all good in a day. Definitely money well spent and I'll be purchasing more soon!
