Abstract
A system for reducing wrinkles on human skin utilizes an electrode to conduct a microcurrent through the surface of the wrinkle into the underlying dermal layer. The electrode is moved in multiple passes along the length of the wrinkle with the electrode in contact with the surface of the wrinkle while generating a periodically repeating microcurrent having a peak amplitude in the range of 10-40 microamps, a peak current density in the range of 10-50 microamps/cm2, and a frequency in the range of 5-15 Hz. The electrode device is self-contained in a battery-containing, cordless case from which a contact electrode protrudes. A hand-engaging second electrode on the surface of the case completes a conductive path through the user's body.
