This product worked for me when nothing else did. I am 19 years old. I developed severe acne when I was 12, and for years could not find anything that could help my skin, which had a crippling effect on my confidence and self esteem. I would cry about how ugly and helpless I felt all the time. I tried over the counter drugs, every type of pill my dermatologist could find, and accutain TWICE to absolutely no effect. Finally a family friend recommended spiro, and I tried it. After 2 months of terrible initial breakout, my skin suddenly started to clear. Within 2 weeks all of my acne was gone. I cant believe how different and free I feel now that I have clear skin.
