Patent number: 8914123Abstract: The invention concerns a method for performing an electric inhibition of the facial muscles for purely aesthetic purposes, using a device comprising a support at the head of a user (1), two contact electrodes (2), an electronic circuit (3) for generating low-voltage electric pulses at said electrodes (2), a direct current electric power supply (4) and means for fixing and locking (7) said components on the head. The invention is characterized in that it includes the following steps: placing the electrodes (2) on either side of the upper part of the nose, at the glabella; passing the electric pulses via the electrodes (2) through the pyramidal muscle of the nose so as to cause said pyramidal muscle of the nose to relax and hence its antagonist muscle, the forehead muscle and the double eyebrow muscle.Type: GrantFiled: September 7, 2005Date of Patent: December 16, 2014Assignee: Cefaly Technology SPRLInventor: Pierre Rigaux
