Facial fat transfer after Accutane?

I am on Accutane and will be done with treatment in a little over a month. My plastic surgeon told me I can have the facial fat transfer procedure after 3 months. He said doing it after 2 months is possible but not ideal because Accutane may interfere with fat retention. He said 3 months will be good. Is 3 months enough time to wait? I really don't want to compromise my results and end up with unflattering results.
