Microneedling on a 1 year old atrophic scar. Morning everyone 1 year ago i was on a ladder, fell, and the ladder hit my forehead. I ended up in emergency with some glue on it. Today my scar looks way better but still looks a little depressed with a thin white line in its middle. I have been performing microneedling treatments at home, every 6 weeks or more. I bet i have done 3 or 4 treatments till now, on it, since i was waiting a full year to finally heal. My question is, can i get rid of the depression using a 2mm needle depth?. Thanks
