and maybe some tips how to improve my skin

Thats good progress my friend. Accutane really works and is a wonder drug for ppl but it is especially important that you stay more healthy if taking drugs like accutane that can tax your body. Tbh I think you will be 100% clear maybe for the rest of your life after a 6 month accutane treatment but you and I both know the dangerous side effects so try to stay healthy, eat more healthier, reduce sugar, increase good fats, maybe some high quality supplements etc. Also dont use any soap or stuff like that on ur face, stick to water only.

I know my doctor said i should take zinc pills and eat healthy

That's amazing o.o Congrats
