overdrying

So like most of you, I've been getting some acne. Thankfully it's mostly mild, but I'm still freaking out. Recently it's bothered me so much I've been really drying it out though 10% benzoyl peroxide, clindamycin, and at times I'd use toothpaste. But I'm not really sure if overdrying will eventually make if worse. If you know that it'll make it better please tell me & I'll continue. But if it's bad, why?

i hate acne so much

I have fairly mild acne (I usually only have several pustules on my face at once), which is not too bad, but its not close to good either. I know that since I've gotten my acne, I've become extremely self-conscious whenever I go outside, which usually makes me constantly touch my face like all the time (which makes me breakout even more) . And I know that touching my face is really bad, but I don't know how to stop. Has anyone broken this habit and would like to give me some tips?
