The new low voltage itch reducer is characterized by having a treatment head comprising a body of electrically insulating material having a substantially flat face surface. A pattern of spaced electrode tips project outwardly from the face surface. The pattern includes electrode tips of opposite polarity in sufficiently spaced relationship so that discharge of electrical current through the air between tips of opposite polarity does not occur under the low voltage employed. The electrode tips at the edges of the pattern define the perimeter of it. The pattern has no face dimension greater than about 20 millimeters. The outward projection of the electrode tips is substantially equal for all tips of the pattern. Pressing the treatment head against a person's skin over an itching insect bits effectively permits the flat surface of the body of the head to contact the skin of the individual with the electrodes pressing into the skin, without penetrating the skin, over the insect bite. |
