Honestly, I found these to be pretty underwhelming. I thought they would be great value for money if they worked, but I didn't find them to be very effective. I have gone through 1.5 sheet of these and I don't find them to work nearly as well as the cosrx patches. The patches are very thin and contain salicylic acid, but I did not find that they did a good job at sucking out any gunk or aid in healing any spots. I also found the thin filmy material to be kind of uncomfortable on the face, and they don't adhere that well on the skin. They tend to not stick/slip around on top of moisturizer. The only good thing I found from using them was that it protected the pimple from getting worse.
