Try some natural remedies. If you have been dealing with this a long time, I dont think you want to start taking any of the strong medicines for the rest of your life.
I have heard that Accutane results are unpredictable. It may render your skin incredibly and unpleasantly dry. It won't only dry your face, so I would worry that there could be consequences for mucus membranes, but I don't know. I have read of people complaining about depression and wanting to commit suicide.
I would try using white vinegar on your oily areas at night. Use a foundation like Rimmel Stay Matte clarifying matte foundation.
I suspect a dietary issue or food intolerance because changing my diet improved my skin. In my case I had Celiac disease, but I also took most dairy out of my diet and fried food. I increased fresh fruits and vegetables. I still eat chocolate and that does not seem to matter. Adding Metamucil could make a huge difference as it becomes a gel and absorbs cholesterol and lowers cholesterol. Seems like that should help your skin too. Worth a try. Skin health is connected strongly with digestion, so it makes sense.
