"well, it worked well for me. i took it back in the early 90&#039;s as a young teenager with moderate acne.  the side effects are bad though, really bad.  my skin was so dry, as were my lips and scalp.  i was sick, had a lot of pain and anxiety and then depression.  i took a 6 month course and it was recommended that i take a second about a year later but i couldn&#039;t face the idea of the side effects. it did, however, do miracles for my skin, it has remained clear some 20 yrs later."
