acne
"I am 31 years old male and currently taking 100mg once a day. I have taken doxy 3 years ago for 4 months and it definitely worked like a miracle back then. I am glad my skin stayed fine for 3 years!! Sad part is..its back again! I never had any side effects especially if you are having plenty of fluids and not mixing with other supplements such as Iron and multivits tablets. In the beginning I felt as if my skin was more responsive to hot and cold temperatures but it's gone now. I would highly recommend doxy to all suffering from mild to severe acnes BUT you have to be patient to see it working!"
