Doxycycline
"Update!- As below I stated that doxycycline and Epiduo did an outstanding job. It continued to do so for 1 and a half months but they say all good things come to an end. Because I was getting used to the tetracycline antibiotic,  I started getting little pimples-definitely not as bad as before so my dermatologist switched me over to Oratane for the cure. I really am so happy doxycycline kick started my clear skin. Don't forget to moisturize and sunscreen!"
