acne
"Doxycycline worked great at first, my skin cleared up super fast, but then after a while I still continued to get a few zits here and there. One of my greatest complaints is how sensitive it made my skin to the sun. I am outside a lot and I used to never get burned, but since on the medication I get severely burned on random places like my nose, hands, ears and feet? I get burned so bad that 2 hours in the sun (with some sunscreen) would result in scanning of my nose and ears. I have recently switched medicine because of this side effect, but if you don't go in the sun you should love the product!"
