Acne and PCOS

Molly
Any help with acne related to PCOS?? I am on metformin and hoping that helps but man, the acne is really bad on my jaw line and under my chin and neck. ANY help would be appreciated. I use cetephil(ABC??) face wash nightly and don't have too oily of skin. What has worked for you?!
