First the treatment area is cleansed and anesthetized. Then the doctor uses a machine that transmits a high-frequency electrical current to a micro-needle. The procedure is performed under strict sanitary conditions. During the procedure, the micro-needle remains above the skin and does not penetrate its surface. There is no blood associated with the treatment. Current is directed into skin growths for one to two seconds, cauterizing them. The treatment area is left open to scab over. After the scab falls off, the treatment area is replaced with healthy skin.
