Can you tell me how i could stop compulsively picking my acne?

Manage it: You're going to pick your acne. That's a fact of life. This isn't why you continue to have acne -- you have it because it's being neglected. If topical benzoyl peroxide as tolerated hasn't cleared you in two weeks, get with your personal physician who can give you prescription-strength Rx as a supplement. If you're offered Isotretinoin for severe acne, consider being brave and doing it. Cheers.
