severe cystic acne

When I was in high school I had problems with acne. I am not sure how it lasted but maybe about three years. I applied difficult products just to get rid of acne and pimples but it didn’t help at all. They said, most teenagers got acne problems then my worries were lessening and I was hoping to go away in the right time. So if you have problems of severe cystic acne, please visit a dermatologist.
