So I was super dubious about this but I had heard great things, and with cystic acne I never knew how effective it would be. But to my surprise it actually works really well, they are annoying to feel on your face but you get use to it and seriously helps reduce healing time of problematic pimple including blind pimples. Also I'm super sensitive to adhesives and chemicals but legit had NO REACTION to them. I'm a big fan and use them whenever a big annoying pimple pops up.
