acne
"I've been on this medication for just over 2 months now, taking 40mg a day. When I started on a low dose, the first 3 weeks I experienced severe dry skin, lips, and especially my nose and under my eyes even. The first 5 weeks my skin broke out worse. And from the beginning I started getting severe back pain. Now in week 9, my skin has settled down and is a tiny bit better, but all my blackheads have disappeared. My skin is still drier than usual, but it's actually improved, and my lips are fine as long as I apply vaseline 2-3 times a day. The only significant side effect I still have is my back and bone/joint pain. So far I'm very happy with what I've achieved (the blackheads) and expect things to keep improving."
