I get microdermabrasion every 4-6 weeks performed by a dermatology nurse at the cleveland clinic, and also get occasional peels. They use a diamond tipped machine, first a courser tip and then a finer one. I'm young and have some mild acne scaring/discoloration, enlarged/clogged pores and overall uneven skin. I dont get very much acne anymore but microdermabrasion helped further reduce it, and my skin just has a healthier, smoother look to it now. I wear less makeup and I actually sometimes get compliments on my skin. It's definitely still not perfect but with a little makeup my skin actually looks good. I wouldn't expect a dramatic change but it does give you the extra little boost to healthy, glowing skin.
