High Frequency Machine

A High-frequency treatment uses low-current high-frequency alternating currents, delivered via a glass electrode. Consequently the treatment is used to aid healing, and also to help desquamation (the skin's natural exfoliation), and stimulate sweat and sebaceous glands. At up to 250,000 Hz frequency, the hollow glass electrode behaves like a glow discharge tube, and is sometime called a "violet ray" or "violet wand", (though the color depends on the gas in the glass). Two electrodes are not required, and sparking may occur when the electrode is close to the skin which clients often enjoy.
