Benzoyl peroxide / erythromycin
"I was prescribed this gel for a reaction to an antibiotic called Cirpoflaxacin that caused severe redness in my skin. I used it three times a day for five months and now have almost completely restored my skin back to its original clarity. I was taken off the gel after it was discovered I had psoriasis versus what doctors had initially diagnosed. 

Persistent usage of this antibotic is imperative for skin clarity. I noticed no improvement in my skin color/inflamatory symptoms until after a month of usage.

My only complaint is that the gel was painful to apply. It stung like a bee sting every time I applied it, often times worse if my skin was really inflamed."
