As stated before, your electrologist would most likely perfer it if you were not useing Accutane during treatment because she or he doesn’t want you to think that the pain you feel, or the state of your skin after treatment is due to the work she or he has done.
Simply put, a person useing this drug, and many others will not have the same experience as someone who has a clean system, and skin that is not under attack by sloughing agents. No one wants to be sued for an infection, or flakey skin, or any other reactions you may get because of something not under their control.
Its not like smoking while using the nicotine patch. It won’t kill you. You will just have to take real good care of your skin during this time. Keep it clean, drink your water, and stay out of the sun! If you can’t stay out of the sun, use the best sunblock you can get your hands on. Thats all.
