I have had one microdermabrasion treatment, and, at first couldn't tell much of a difference. But now, my skin definitely looks smoother - I also use Arbonne RE9 skin care, and find it to be amazing. Their new Line Defiance foundation is like Botox in a bottle. I plan to do the micro once a month for the next 3 or 4 months (I am 58, and have a lot of old skin buildup)and will keep you posted on the results, although, I don't have any scar issues to report on. The micro helps your skin products work more effectively.
