  • Patent number: 7211090
    Abstract: The invention is directed to an appliance for the epilation of the human skin, having a housing to accommodate a motor and a drive mechanism for driving at least one clamping device (43) by which the user's hairs can be extracted. Moreover, a stimulation mechanism is provided to reduce the sense of pain during epilation. This mechanism includes at least one element (55) that is movable toward and away from the skin when the appliance is placed in epilating position on the user's skin. According to certain embodiments of the present invention, the at least one element (55) has a free end (56) and is arranged adjacent to the side of the rotary clamping device (43). In consequence, the user perceives at least subjectively a reduced sense of pain during epilation. Still further, a method for epilation and a method for the use of the appliance of the present invention are described.

  • Patent number: 5704935
    Abstract: An appliance for epilating hair of the human skin includes an epilation head with at least two electrical conductors and a clamping device for gripping and plucking the hair. The electrical conductors at least temporarily engaging the skin during hair plucking. A casing is attached to the epilation head and a motor housed in the casing drives the clamping device to cause the clamping device to automatically and periodically perform its functions of gripping and plucking. A generator electrically connected to the electrical conductors provides a stimulator current to the skin when the electrical conductors are in contact with the skin so as to electrically stimulate the nerve system under the skin during hair plucking.
