Accutane is a cancer drug that is widely known to cause erectile dysfunction. Acne scars are superficial and can be hidden and treated, a droopy you know what can't without old man viagra pills. As a young man who finishes Accutane, you may end up with flawless skin, but you may have the sex drive of a 90 year old nursing home patient. It's kind of funny, guys take Accutane to look good and pick up chicks, but many of them now can't actually do anything with them. Actually, its NOT funny. It's horrible.
It also causes psychosis, organ failure, stroke, hair loss, and suicide. I don't want to go on a 2 page tangent about the side effects, read the medical journals and FDA reports. They are far understated than what the people on this board believe based on heresay or their Dermatologist/paid spokesperson. Medical journals are now catching up and recognizing that a good portion side effects are occurring years after Accutane cessation. There is a reason Roche pharmaceuticals discontinued it, they could never win the lawsuits that were coming their way every day.
Focus on your diet. You say you eat practically everything and drink milk daily. Please, for the love of god.... lay off dairy, limit refined carbs, and use herbs like thyme and oregano. Try to limit grain carbs in general. Eat lots of beans, starchy vegetables (limit potatoes though) instead. Juice a ton of fruit and vegetables. Take zinc. But most importantly, stay away from things like cookies, chips, french fries, bread, pasta, rice, etc. Switch to brown rice, whole wheat pasta, corn tortillas if you must have these types of foods, but try to get at least half your carbs from legumes and veggies. Also, don't shave, use a beard trimmer only. Take probiotics every day or every other day and make sure you are getting enough Vitamin D (go in the sun).
I know you have an appt soon but what are you really expecting? 95% of them just switch up meds, which are band aid solutions that only treat the symptom. Try to make an appointment with a naturopathic physician as well, or a Dermatologist who understands the lifestyle-diet-acne link. They will be much more empathetic and will tend to lay off the heavy stuff and try to find a real reason you are getting acne. Remember, most developing countries who are not exposed to our diet have little to no acne at all. The American Academy of Dermatology actually acknowledged for the first time in 2013 that studies have known proven diet and acne have a direct link, particularly through insulin responses and allergic reactions.
Holistic and/or practical minded derms try to avoid hurting you with dangerous chemicals just to keep their job. I have been to one of these types in my lifetime and they gave great advice about supplements, practical things you can do, etc. They offered prescriptions but never forced them on me, while also telling me there were plenty of other things I could try which are just as effective if I wanted to keep my insides safe.
WOW what a concept, first do no harm....
