I am 43 years old, female, suffering from cystic acne since I was 13 and not cured but 80% cured. The only advice I can give you after so many years of this horror desease is not wasting your time with topicals, as I did.
The only thing that improve my skin (but not cured) was the ingredients antiDht as Diane35, zinc 50 mg, pumpkin seed oil 50 mg, and recently I have started taking SawPalmetto. I also think tha Spiro has been a great solution for some people, but I have low blood pressure and I fainted the first week with just 50 mg of Spiro. Check out Green Gables posts about Spiro, they are awesome.
