ok don't listen to Frodo, he really is NOT a doctor. and instead of choosing something off an infomercial, this is what you can do instead.
Choose a good non-comodogenic soap. Cetaphil is a good brand. If you cannot shower at your facility, at least wash your face with this stuff. It doesn't leave any oils or fragrances on your face, and will help to get all that dirt and other misc stuff that's sticking to your face after rolling.
If the acne continues, then I recommend a low % benzoyl peroxide cream. Anything over 5% is too much and will instead dry out your skin. The "miracle cure" in proactive, believe it or not is actually 3.5% benzoyl peroxide. Neutrogena has a 2.5% cream called "On The Spot."
Wash your face with the non-comodogenic soap, and apply the benzoyl peroxide to your face. Once in the morning, and once at night before bed. I guarantee that it will clear up majorly in 3-4 days. If the peroxide is drying your face out, then get some facial lotion - oil free, preferably SPF15.
It should only cost an initial investment of $20 or so, and will help out a lot.
