I've had acne (moderate/severe) for about 8 years now, but lately I started breaking out badly on my forehead. Then, on my chin and cheeks. I was so fed up with it, and had to find a solution because I didn't want it to get worse.
So, I went to a dermatologist and she prescribed me Doxycycline. I took 100 mg once a day. It took a while (1-2 months) for it to work, so be patient. First, I broke out like crazy, then after a while it cleared up.
Now, I am on my third month of taking it and I am very pleased with the results. I am acne-free, but every time I forget to take my prescription (let's say for two or three days) I get a zit or two, so I am a little hesitant to get off my meds, because I know it will come back to haunt me again.
