"i took this medication a couple years ago. within just a few weeks it was working amazing and my skin was clearing up and looked great!!! i went off the med so that i could go on birth control.  i&#039;ve had trouble with several birth controls and now 2 years later at the age of 22, i&#039;m not currently on any form of birth control so i started this up again about 3 months ago for my acne. i was on it for 2 months, never missed a dose....and there was not one change in my skin.  i&#039;m sure it all depended on my health 2 yrs ago and now, the different meds i&#039;m on now and wasn&#039;t in the past, etc. several factors could be played as to why it&#039;s no longer working for me at this time. so i&#039;d say at least give it a shot because when it did work, it worked!"
