I am using steriods for low platlets as suggested by my doctor, my skin is getting darker what should I do?

I have moon face syndorme also,

I know you probley have heard this already but I think the only thing you can do is talk to your doctor or dermatologist and see if the steroids are causing it and if so u should stop the use and ask your doctor about something different because obviously your body is responding to it in a bad way.
