The risks of any surgical or cosmetic procedure that causes even slight skin injury while on Accutane or within 6 months of stopping treatment are well known. Although not everyone has problems, if you do, would it really be worth it? Patients even postpone necessary surgical procedures until after Accutane is out of their system. Please wait the 6 months after treatment to insure your tattoo looks it's best and won't cause excessive scarring which you will NEVER be able to get rid of.
Thank you for your question. A side effect of Accutane is skin sensitivity and an increase risks of scarring if any trauma or injury is done to the skin, which includes cosmetic procedures such as chemical peels, microdermabrasions, laser treatments, tattoos, or piercings, etc. Getting tattoos while taking Accutane may result in scars or keloids; therefore, in my opinion, postponing getting a tattoo while taking Accutane is the best choice. I highly recommend you consult with your prescribing physician regarding your questions and concerns. Take care and good luck.
