"i started having hormonal acne in my late twenties and i went through all the over the counter treatments including proactiv and murad but nothing worked... i went to the dermatologist and 
she put me on this medication 100mg and it has worked great, i been on it two months and the oilyness and bumps are gone!!! in the beginning my face became really dry due to this medication but just get a good moisturizer and it will be fine!!! it rocks"
