"i&#039;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&#039;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&#039;ve only been using doxycycline for about 2 weeks but i haven&#039;t had a single pimple since i started. it&#039;s completely amazing, and fixing my gross bug bites at the same time. i&#039;ll just have to see how long my skin can stay clear."
