Direct-high frequency is considered a timeless rejuvenating treatment for the skin. The first high-frequency appliance was developed in the late 1800s by the renowned scientist Nikola Tesla and he originally named it “Violet Ray” due to the purple gas it was producing.
At that time it was specifically used for medical purposes to treat infections because it was particularly useful in the healing of wounds. In the 1970s European salons discovered the healing benefits of direct high-frequency electrical stimulation on the skin. A mere ten years after that, this technology became widely used in North America by skin experts.
It was considered to be a very safe and non-invasive procedure with no side effects at all and it became extremely popular amongst licensed aestheticians who used it to provide treatments for many skin conditions ranging from acne to wrinkles and even hair loss.
