Thanks for your question.
Even though you only took accutane for 3 weeks, you are right to be worried about potential delayed healing with any wounds from laser resurfacing. Any procedure that damages the surface of the skin leaves you at risk for abnormal or prolonged wound healing.
In your specific case, it would have been better to have waited at least a month after discontinuing accutane prior to doing your procedure. For a full 6 month accutane treatment, we don't recommend any procedures for up to 1 year. But, in your case with such a short treatment course, I believe you should be fine.
Continue to use ointment on the area, avoid being rough with the wound, and allow the scab to stay on AS LONG AS POSSIBLE. You have one good chance to heal, so take care of the area very gently and very well.
Good luck!
