I have rolling, boxcar and ice pick scars in concentrated areas of the cheeks, I have been going through a whole treatment plan with my doctors that include chemical peel, derma pen with prp, and laser. Now the doctors are thinking about doing subcision and fillers next. Can the fillers be injected right after the subcision or would I have to wait? Also does subcision only work with certain type of scars, or all? And if so which?
