I used to think my acne was a hormonal imbalance. I don't have problems with blackheads but my face kept breaking out. I starting using liquid minerals and that seem to help. I have read acne is a sign of mineral deficiency such as zinc or sulfur, which can be caused by mercury.
But when I got my 3 large fillings out it cleared up within 2 weeks. As far as products I use organic tea tree cleanser and cleaning pads.
