I am 60 yrs of age, have olive complexion, some pigmentation, sun damage and open pores. Sounds terrible but really not in too bad condition. My concerns are, scarring from the treatment and is it possible that it may make my pigmentation worse. Besides having normal to oily skin, my skin is quite sensitive. I have been previously advised by a dermatologist that dermabrasion would not suit my skin type. Any advice, comments would be much appreciated.
