I'd be careful with the Yaz, personally. I always had mild acne and went on Yaz a few years ago to regulate my heavy periods. I was on it less than 2 months and it gave me horrible cystic acne including on my cheeks where I NEVER broke out before, among many other awful side effects. As I said, I was on it less than 2 months and I continued to get painful cystic acne for several months afterward and dealt with the scarring for a couple years. It's mostly better now, but there are still some scars. I'd just be cautious considering your acne showed up when you stopped it, which suggests that its effect on your hormones may be partially to blame. Either way, I agree with seeing a dermatologist and I definitely understand how you feel!
