Because acne is hormone related many believe that the pill works wonders because it regulates your hormones, but for some there can be an adverse effect which might trigger your hormones even more as opposed to regulating them. I've been using proactive it seems to be working also don't use anything with alcohol in it, it might make your acne worse. I've also been controlling what I eat and trying to stay away from fried food, junk, red meat things of that nature... Good luck!
P.S picking causes scarring I used to pick too but you have to force yourself to stop
