"i am 19 years old with severe acne. i took this when i was around 16 or 17 for about 3 months. i was never happier with how my face looked i had absolutely not one pimple after taking this for 3 months but i stopped taking it because i was happy with the results when i was supposed to take it for 9 months. don&#039;t do that! because my acne came back almost just as bad. i hear if you take it for the full amount it works though. i honestly had no real side effects. i think because i only took it for 3 months."
