1. A microstructure apparatus, comprising:

  • a substrate; and

    a plurality of microelements affixed upon a first surface of said substrate;

    said plurality of microelements being of predetermined sizes and shapes for use in scraping skin cells from skin when said microstructure apparatus is placed upon said skin and moved in at least one direction;

    said predetermined sizes and shapes including at least one substantially sharp edge at a distal end of the microelements, said predetermined sizes and shapes having a characteristic such that the microelements do not create substantial focal discrete points of pressure on said skin;

    said plurality of microelements having an inverted wedge shape each having at least one side wall, the plurality of microelements form open areas between at least some of the side walls of adjacent microelements, the open areas being configured for accumulating skin cells.
