Is it okay to use laser resurfacing for acne after you have been on roacutane (oral pills)?

Depends. It depends on how long ago you were on the meds, how high the dosage was, and if you need laser resurfacing. Your doctor can evaluate that during a consult prior to booking the procedure.
wait 6 months. If you have been on Accutane you must wait before getting laser resurfacing. I usually tell my patients about 6 months to be on the safe side.
