question: Hi doctor, I am 21 years old. Before two years, I went to a dermatologist for my acne problem. He prescribed me Ziana. It helped for about three to four months. I used it for a year. I still have acne. But it got worse. I use PanOxyl at night with acne free toner and a cleanser in the morning. I want to have good results. I am having acne problem for about six years. Recently, it has got worse now. I have large multiple white and blackheads on the cheek, chin, and jawline. Please help.
