Stem Cells and Derma-stamping?

A dermatologist in Korea is selling "grow factor derma-stamping". His claim is that 2-5 treatments, which involve the use of cells from human tissue, will create thicker, clearer skin. He also claims this is FDA approved. He stated he invented this specific treatment. The cost is 400USD/session. I would appreciate your comments. I have a friend who swears by this treatment.
