"a year ago my doctor prescribed doxine (doxycycline) and i found that after about 2 weeks of taking a tablet a day and increasing my usual water consumption, my skin started getting better and much more clear. a relief after struggling with mid-teen acne. eventually my skin was fine (3 months after starting) and i stopped, thinking that it was now my body and not the medicine that was healing my skin. but soon afterwards my acne started appearing once more, and so i began taking doxycycline again about 2 months ago. it&#039;s been great and i&#039;ve really got my confidence back as my skin naturally is quite oily and acne prone. note that while taking the medicine it is still common to get a tiny pimple or two sometimes as the drying process of the skin isn&#039;t so intense on this medication. my only side effects were my increased desire for water and a slight aversion to strong sunlight."
