Hello Dr. Naderi
I had a microdermabrasion (with the vacuum and crystal machine they use in the dermatologist office) done a few years back and it was a bit rough and somewhat painful. The overall result was good, the acne scars went away and there really is not anything major to complain about. I did however notice a small change in the texture of some places on my cheeks. This is not hyper-pigmentation as the color is not different, but there seems to be rough patches on my cheeks that make my cheeks look a bit rough under certain lighting.(many tiny tiny little skin colored bumps). I cannot say if this appeared before the microdermabrasion or after as I just really starting noticing it recently. Does this have anything to do with the rough mechanical microdermabrasion? Or could this just be my skin being itself?
Microdermabrasion is a very light type of resurfacing that is used more as a maintenance and prevention tool. It is not aggressive or deep enough to make major changes to the skin. Now if the microdermabrasion is done too aggressively to the point your skin bleeds or gets scratched then problems could occur. I saw an African American patient who got keloid scars on her face from a bad micro-dermabrasion done at a spa. If your skin looked good after the treatment and the treatment was a few years ago then these textural issues are most likely unrelated to the microderm. I would suggest you see a dermatologist so he/she can check your skin.
