I am Male, 30yrs, oily skin. I had normal acne on face only, for 16 years prior. While I was traveling around the world for 6 months, I was taking one DoxyCycline pill a day (continuously) for those 6 months. After 1.5 months of taking Docycycline, the Acne cleared. However, after I stopped taking the pill after 6 months, I have permanently fixed Acne. I dont even have to wash my face any more! These should be taken under direct medical supervision as they can cause severe side effects in some users. But I did not seek medical advice. While in Thailand, with no script, I asked for a 6 month supply of DocyCycline (very low cost) to assist in preventing malaria. I experienced no side effects at all and I accidentally found it fixed my acne for good. Im SO happy. I'm now 33 yrs old and never breakout anymore.
