If Accutane Does Not Cause Rosacea, Why is the Flushing Still Persistent After a Year?

Hi, I have been taking accutane for merely a month, but the dose was too high in my opinion. I have had flushing and blushing throughout the month. Time later, although the blushing is gone, the flushing remains. When i press on my skin, my skin blaches and it is like that on my entire upper body. My skin is not dry and not sensitive anymore (it went back to normal once i stopped the medication). Why am i still flushed?
