acne
"I've always had moderate acne around my chin and forehead. I tend to get white heads and occasional cystic acne. Now in my twenties, I've been able to manage my skin fairly well, I know my acne triggers and to keep my face clean every night. I ended up using doxycycline for a medical purpose (I went to South America and got bit by a nasty bug) and found myself with clear skin. I've only been using doxycycline for about 2 weeks but I haven't had a single pimple since I started. It's completely amazing, and fixing my gross bug bites at the same time. I'll just have to see how long my skin can stay clear."
