Summary for Patent: 9,005,158
Title:Eradication of pigmentation and scar tissue
Abstract: The invention is a non-surgical method for the eradication of pigmentation and scar tissue from an area of skin. The method comprises repeatedly puncturing the area of skin with an array of needles. As the needles are inserted into the skin, the needles and surface of the skin are washed with a clean solution. As the needles are withdrawn from the skin, the flow of clean solution ceases and the dirty solution, which contains cellular fluids and pigments released by the action of the needles, is removed from the surface. The invention is also a solution, which is used to clean the needles and to aid in destroying the pigment containing cells, and an apparatus, which is especially designed to move the needles into and out of the surface of the skin and to provide synchronization of the motion of the needles and flow of the solution such as to maximize the effectiveness of the method.
