Doxycycline
"I have suffered from moderate to severe acne. My doctor prescribed me this medication the first week of July 2015. I literally saw NO results until after 4 weeks. I told my dermatologist that it doesn't look like it really works for me BUT, he told me It usually takes 3-4 months to really see the improvement. Also, a week after I saw him I did see a HUGE improvement. I had a lot of bumps on my forehead and all around my chin. My face is very smooth now, just have a couple of scars. Nothing good makeup can't hide when I have to head out. I also avoid the sun as much as I can. Bc I started to notice my skin was getting flakey but I use a good moisturizer to get rid of that. I take one when I wake up and one before I go to bed."
