Doxycycline
"I've had acne since I was 12 and had tried several topical antibiotics but they never seemed to work. I went to the Dr and he prescribed me 100 mg doxycycline hyclate once a day and duac gel twice a day. The first few weeks it dried my face out but not TOO bad.. Just be sure to stay moisturized and drink lots of water other wise it'll be worse. After about a month I seen results here and there but I'd still break out. 2nd month started to get a little better. I'm now on my 3rd month (almost finished) and I honestly can't believe how much of a difference I see from when I first started taking it. All I have is a few scars but that's NOTHING. I'm so excited!! I've been waiting for this day forever :) I highly recommend it."
