rosacea
"I've been struggling with Rosacea for a long time. Skipped the red vein part and went straight for the pimples, boils. Later purple thickness and seborrheic eczema came with it too. I did not like the idea of using antibiotics. Don't like the thought of treatment resistant bacteria as a result. But, I had to take something. 
First night after taking doxycycline, I woke several times, because of extreme itching. Everytime I went to the bathroom and saw my face in the mirror that night, it looked already a bit better. 
The pain Rosacea brought me was gone in a week. The flakes of the seborrheic eczema after a few weeks. The last pimples disappeared a few weeks after that, to only return, very mildly, just before menstruation."
