I've been getting dermaroller/dermabrasion procedures done by my dermatologist for acne scar treatments, but I tend to occasionally break out (a few here and there, cystic/nodular acne). My dermat recommended that I be on a low dose Accutane regimen for maintenance since my occasional breakouts are going to end up causing scars again while I still continue w/my dermaroller sessions. He says a very low dose of Accutane for maintenance won't really affect anything, is this true? Is it safe?
