Which is more effective micodermabrasion or glycolic peel?

in getting rid of acne scarsWhich is more effective micodermabrasion or glycolic peel?
It really depends on your skin type. I never had microdermabrasion or glycolic peel. I only had diamond peel.





But my brother tried both and the more effective one was microdermabrasion. He has very oily skin and really a lot of pimples. He's been doing that for like three months and the results are really visible. The acnes lessen and the scars starten to disappear and his face somewhat lighten.
