I was super excited when I ordered these because I didn't know acne patches existed!  I totally thought this was going to be a game changer and it has!  But only on whiteheads.  I get papule acne on my jaw and chin and these don't work so well on those.  They shrink in size but not significantly enough that I would consider sticking one of the patches on.  I'm going to make my way through other brands but if I don't find anything better, I'll probably repurchase these but reserve them for whiteheads.
