What Is High Frequency Current?
The high frequency current is an alternating current called the “Tesla Current”. This current can produce a 60, 000 to 200, 000 hertz frequency, depending on how it is regulated. (The frequency indicates the repetition of the current per second). High frequency treatments may involve placing the electrode directly on the skin (direct high frequency) or leaving a gap between the electrode and skin (indirect high frequency). The glass electrodes are filled with a gas, either Argon (produces a violet ray) or Neon (produces an orange / red ray).
The Difference Between Argon and Neon Gas:
- Argon – used on Acne-type lesions
- Neon – used on general Oily-type skins or to create warmth in localized area for improved product penetration.
(It is the ELECTRODE not the machine base unit to determine the different gases)
High Frequency Treatment Applications:
1. Direct High Frequency - Is an external application that produces a germicidal effect through ozone formation of the skin’s surface, via the glass electrode, where the air sparks between the electrode and the skin combines with oxygen.
Use for Direct High Frequency:
- Acne-type lesions using an argon gas electrode for a “sparking” treatment.
- Oily skins with overall congestion using a neon gas electrode for drying and germicidal effects.
2. Indirect High Frequency - Is the use of the current for relaxation and sedation. Unlike the direct method the current flows through the surface of the body, and has a regenerating action.
Use for Indirect High Frequency:
- To aid penetration of a treatment cream/ampule by increasing blood flow in certain areas, whereas infra-red or massage would stimulate the entire face.
- To assist in massage for an aging skin using the indirect method.
