I have had Acne for about 28 years, believe it or not. I had done just about everything except go on Accutane to cure it. The only thing that worked was liverflushing and doing a lot of bowel cleansing, and that included getting colonics.
I had done tons of bowel cleansing, fasting detoxes, and a ton of candida cleanses, but nothing really PERMANENTLY cured me.
If I keep my bowel clean and liver flushed, I have no Acne at all. I do take supplements and I also had all my silver mercury Amalgams replaced, because mercury exposure causes terrible candida, a HUGE contributor to acne.
Persistant Acne can be a huge puzzle, but with the right knowledge, you should be able to cure it, but you MUST take a multi-pronged approach. Bowel cleansing is a MUST for people with acne....it's just as important as liver flushing. I did a kidney cleanse, and that seems to have helped as well.
