ABSTRACT:
An apparatus for skin therapy employs a circuitry for generating a high voltage that is connected to an electrode. The circuitry to step up voltage from a power supply includes a transistor, transformer and rectifier; and the means to control application of the stepped up voltage to an electrode coil or transformer includes a silicon controlled rectifier in series with a capacitor and an output transformer's primary. Pulsing means, having voltage supplied from a power source on a separate circuit, to control the rate of silicon controlled rectifier firing and therefore discharge of the capacitor includes a unijunction oscillator and transistor. The output transformer's secondary powers the electrode.
