Rosacea
"I have rosacea triggered by heat/intense exercise. Went through 2 rounds of accutane in college, which helped for a short while. Got reprieve through my late 20s/30s, then it game back in my 40s w exercise. Tried to treat it naturally for two months, then gave up and saw the dermatologist. Started the doxycycline 1 pill 2 times a day and my face, which had virtually every pore affected with a bump --and under eye area affected, was almost completely clear in one week.  After 2 weeks I went down to one pill per day. On that dose I get a couple bumps after working out, but they go away in a day instead of 3 weeks. Also do the metro gel and sulfur wash. Been a month now. A little heartburn/sour stomach after taking it, but excellent results."
