  • Patent number: 8165698
    Abstract: A face mask for cleansing of facial skin. The face mask 100 comprises two or more electrodes 22, 23 to which an electric cleansing signal generated by a cleansing signal generator of the face mask is conveyable, the electrodes provided in the face mask 100 being arranged as electrode pairs 24 which comprise a positive electrode 22 and a negative electrode 23 such that all electrode pairs 24 reside in the face mask 100 substantially in the facial area. The face mask is characterized in that the outer edge of the face mask 100 has an edge portion 101 provided with gripping means 120 for fitting the face mask onto the skin of a user of the face mask.

  • Patent number: 7069088
    Abstract: A skin cleansing device comprising includes two or more electrodes attached to the cleansing pad, a cleansing signal generator for generating an electric cleansing signal, and elements for conveying the cleansing signal from the cleansing signal generator to the electrodes. Electrode pairs include a positive electrode and a negative electrode located in the cleansing pad. The cleansing signal generator operates on low voltage direct current and generates a square wave alternating current cleansing signal with a voltage lower than 5V and frequency higher than 2000 Hz. The cleansing pad of the cleansing device has a sandwich construction, including at least a detachable absorbent layer receiving a cleansing solution to be arranged against the skin, a layer receiving the electrodes and an outer surface layer.

  • Patent number: 6694183
    Abstract: A skin cleansing device for cleansing facial skin includes electrode pairs attached to a facial mask and a cleansing signal generator for generating an alternating electric cleansing signal, the electrode pairs being operatively connected to the signal generator to apply the cleansing signal to charged molecules of the cleansing solution located at mask absorbent areas to create alternate backward and forward motion of the facial skin surface.
