Would removing mold from my bathroom walls cause me to break out in acne? i took accutane and im 6.5 months off accutane.

Probably not: I'm glad you stayed the course while taking Accutane, a challenging but rewarding medicine. Acne can recur by itself after a few months, as was probably explained to you when you took the medicine. It may be easier to manage now. It's seldom helpful to try to second-guess what's causing your acne -- simply care for it. If you need to get out the benzoyl peroxide, please do so. Best wishes.
