When i went to back to my dermatologist to ask why I had been prescribed accutane in the first place, he told me for scarring. I said " I thought it was supposed to be a last resort treatment?" he replied " Haha, not at all." Through everything Ive ever known and learned, I have never once heard of accutane being prescribed for mild acne and scarring. If anything i know that accutane slows the healing process and therefore can lead to more scarring during and after the treatment, but can possibly prevent future scarring.
