I had microdermabrasion done a few years ago to help smooth out the area where my scars had healed (thanks to the dermaroller). It was really bumpy because of the new skin. I got it done every 2 weeks for about 3 months and then monthly for a few months. My complexion was bright and smooth. After the 3rd treatment, my red spots disappeared. My skin was smooth and the scars I had were less visible. I loved it. It will NOT get rid of indented scars. Had to stop getting treatments because my dermatologist moved to the other side of town (30min. drive) and I can not find any good estheticians on this side of town.
