I buy microdermabrasion treatments when they are on sale. I will pay up to $60 for it but that is tops. Often, ads will be running special for half that.
I like how it gets all the dead skin cells off and makes my skin feel smooth. I don't listen to any claims beyond skin smoothing because it has never make a difference on me for problems like uneven skin tones or dark spots. They hype up the benefits of it.
When I have a little extra to spend and there is a special on it I do it. If you go in with realistic expectations you will enjoy the treatment and not be disappointed. It doesn't hurt but it is somewhat uncomfortable like rubbing your face with fine sandpaper. Well, not even quite that bad.
