Abstract:
1. A controlled abrasion device comprising a hand piece, an abrasive tip, a feedback control mechanism, and an electrical motor, wherein the abrasive tip does not contain a micro-needle, wherein the feedback control mechanism comprises (a) a source electrode, (b) a return electrode and (c) a controller, wherein the source electrode is located in the abrasive tip, wherein the return electrode is located at the proximal end of the hand piece, wherein the abrasive tip connects directly or indirectly to the motor such that the motor is able to cause the abrasive tip to move, and wherein the abrasive tip is attachable to and removable from the proximal end of the hand piece, and wherein the source electrode and the return electrode are in electrical communication with the controller, and wherein the feedback control mechanism measures the conductance through the skin in real time and calculates in real time the rate of change in the conductance over time when the device is applied to the skin to control the level of skin abrasion.
