I've had micro-derm today......it does improve the appearance of the skin. However, my dermatologist put me on a vitmin c, skin lightning lotion and 30 block sunscreen every day. Also I had the "photorejuventation" laser treatment which is expensive but I am "of a certain age" so I thought why not! And, it has truly made a difference.
Ravinder's day spa on 4th St. between Washington & Bloomfield does micro-dermabrasion so you could ask her for a test patch. Hope it helps!
