I never had acne anywhere other than my forehead for years, but lately I have been breaking out on my back and chest. I m a 21 year old female, and for the past year my menstrual cycles have been both unpredictable and debilitating. They have also been surprisingly frequent (sometimes I start a cycle only ten days after finishing my previous one), to the point of having two in one month. Why could this be happening, and could the upheaval in my hormones be connected to the acne on my back and chest? I eat healthily, drink plenty of water and get enough sleep every night. I ve also been taking vitamin and mineral supplements (B12, C and Zinc) in an attempt to regulate both my cycles and my skin issues. Any answers are greatly appreciated!
