acne
"I had very bad cystic acne and had to see a dermatologist. She prescribed Aczone and Tazorac, it did not work, it made me breakout worse.  I went back to her and she prescribed doxcycline an antibiotic and within the first week  I saw an improvement. I am on antibiotics, Aczone, and Tazorac, which together works awesome, my dark spots and acne scarring is fading also."
