Omg where has this been my whole life? Why has nobody talked about hydrocolloid patches when I was a teen? These truly do shrink your pimples (as long as it is an open or popped one). I just put one on before bed and by morning, viola! All that's left is a small bump, if anything. Seriously couldn't believe my eyes. (All those years of suffering from acne! I'm in my 30s now with hormonal acne btw.) I also wish there were more smaller circle patches since i don't really have that many giant pimples. But it doesn't matter. These are magic! Get this now!
