I've had microdermabrasion before so knew what the treatment entailed. As it was my first time at this salon I had to sign a waiver. A lot of the content in that waiver wasn't stated to me though, maybe because I told the beautician I had microdermabrasion before. I thought that was a bit of an oversight. The treatment was good, the part I didn't enjoy was the white head extraction which really hurt. Next time I'll ask the beautician to leave them alone.
