How long does it take for the proactiv acne solution to help your acne go away?

Maybe never: Prescription stuff works much better and even in our loony health care system should be cheap enough. I start with topical clindamycin, with a topical retinoic acid derivative if there are blackheads, moving to systemic antibiotics as appropriate if these prove insufficient. This is the 21st century and you deserve better than a labor-intensive benzoyl peroxide kit. Good luck.
