Is this rosacea or flushing from Accutane? (Photos)

I've been on accutane for 5 months, and I'm about to start my 6th month. My face has been really red and I'm not sure if this is rosacea or a side effect from the medicine. I know that flushing is a common side effect but my dermatologist hasn't been able to tell me wether it is rosacea or a side effect.Im just looking for help because this is the only thing left from my accutane experience that I'm self conscious about. I appreciate the help.
