"i took this in my sophomore year in high school since i was suffering with severe acne all over my face, chest and back. astonishingly, it cleared it all up within the second month. i felt great but got a call from my doctor saying that i should immediately get off this medication because my liver function tests sky rocketed. it was very scary but my liver eventually recovered. a year later my acne came back, and came back hard. it was hard to go to school and i had bad cystic acne. i talked to my doctor and decided to go back on. i am now two months into the medication again and seem to be having a lot more side effects. i&#039;m still experiencing bad acne with redness but i know it will clear up sometime. as for the liver, every things fine so far."
