acne
"I had severe acne on my face, chest and back. My dermatologist prescribed me doxycycline and at first the medicine seemed hopeless, but with time (approximately 8 weeks) I started to see results on my face. Within 3 months my face was completely clear. Unfortunately, my face was clear for only 2 months and I began to have cystic acne again. I'm switching to Bactrim because doxycycline has stopped working and the glory was short lived."
