Hand holdable human skin treatment apparatus

An electrical human skin treatment apparatus which comprises a housing within which is incorporated an electrical circuit. The housing includes a pair of terminals which are spaced apart. The user's hand must be in contact with one terminal with the other terminal to be in contact with the area of application such as the face or neck of the user. The electrical circuit includes a slow voltage current rise to minimize the possibility of electrical shock to the user. A switch is incorporated on the exterior of the housing to not only activate the apparatus, but also to select anaphoresis or cataphoresis.

Claims

2. The hand holdable human skin treatment apparatus as defined in claim 1 wherein:

said electrical circuitry including slow voltage current rise means which causes the operating voltage and current within said electrical circuitry to rise slowly so as to minimize the possibility of electrical shock to the human user.

3. The hand holdable human skin treatment apparatus as defined in claim 1 wherein:

said housing including a reversing current switch for reversing said current, said reversing current switch being connected to said electrical circuitry, said reversing current switch being manually movable between a positive position and a negative position, with said reversing current switch in said positive position a cataphoresis charge is conducted between said first electrical conducting terminal and said second electrical conducting terminal, with said reversing current switch in said negative position an anaphoresis charge is conducted between said first electrical conducting terminal and said second electrical conducting terminal.
