Doxycycline
"This really works. Battled with acne, pimples, rosacea most of my life. Been taking this for 8 months. The difference is so good. I am 44, in Australia it is a cheap medication. Doctor says to stay on it as a low dose. Worries me a bit, but having been off it only a week, my skin is awful. Chin outbreak of awful hard pimples. So I am going back on it. Hope that's not a bad thing on my body but I am far less stressed and happy."
