The salon called me to ask me to come in an hour earlier if possible as they had a free slot. However when I arrived the door was locked and I had to call them to let me in. Once in, I still had to wait 40 mins before they could start the treatment so I don't know why they told me to come in early. I had never had a microdermabrasion treatment before and informed them of this. I expected that perhaps I would have a consultation or at least a description of what to expect but I got nothing. I can't compare the results to anything but I could see no difference afterwards.
