Acne
"I started taking Doxycyline this week, and already my skin seems to be getting better. I&#039;m 20, and recently developed bad acne on my back, as well as a mild case on my face. After five days, my skin is clearer. I haven&#039;t had any of the nausea people have mentioned, although I occasionally get cramps if I haven&#039;t eaten. I have noticed that I&#039;m getting sunburnt easier, but that&#039;s nothing a good dose of sunblock can&#039;t remedy."
