Accutane
"Don't let the bad review deter you. I was a teenage with very bad acne: on my face, on my back and I couldn't do anything without being self-concious. 
I tried everything from topical creams to oral meds like doxycycline to stuff like Proactiv. NOTHING WORKED.

When my doctor suggested that I get on Accutane I was hesitant. I had to take a pregnancy test among other tests every month. But I agreed.

Yes I did have extremely dry skin, and severly dried lips. but honestly...when you have severe acne that is nothing in comparison. 
Now I'm 22 and my skin is CLEAR! My back is completely CLEAR! Its a miracle. 

If you have acne you HAVE to try Accutane."
