I've had hormonal based acne recently, and I still don't know what hormone was the problem. I ended up seeing my MD and she perscribed a face cream wiht a low dose of antibiotic that helped clear it up. I've been ttc for a while now, so my OB is doing blood work to check my hormone levels.
I wish I had better advice. I do know there are a lot of mom's here who take a variety of herbs to help balance hormones such as: Vitex, red raspberry leaf, and vitamins like B6. I think finding which one works for you is a trial and error thing though.
