This is a holy grail. Due to hormones, i sometimes break out here and there. And lately because I'm using vitamin C serum, it's purging my skin so more pimples (yeay me). This is a life saver for two reasons, 1. I don't get to touch my pimples when i have the patch on, 2. overnight, it literally sucks out all the puss and yucky things and once you remove it the next day, it all transfers to the patch. Sometimes I do have to use another one (especially for the more difficult pimples), but in the end, I do not end up scarring, which has been a problem with me before. I would only recommend using it after your white head is visible. Anything before and it won't really do much. I will be re-purchasing it for sure. Also, the big patches, i would suggest to cut them in half b/c they're usually two big. You at least get two uses out of it.
