Bren:
Microdermabrasion is basically a superficial sanding process. If it's overdone, there can be irritation and bruising, but these are rare, and in any case not permanent. Properly done, this procedure can make the skin look and feel smooth, though of course it needs to be combined with other procedures, like skin rpograms based on
RetinRetin a micro gel
Retin a micro gel pump
Retin-a-A, or repeated every couple of months to sustain improvement.
Best.
