High frequency (also known as the Tesla high frequency current) was first developed in the late 1800’s by renowned scientist Nikola Tesla. While it offers a number of functions, before the invention of ‘modern’ antibiotics it was largely used for medical purposes such as in the treatment of strep throat and other infections. In the 1970’s, European salons discovered the cosmetic and healing benefits of high frequency electrical stimulation on the skin and by 1980, the technology became widely used by skin care professionals. using a Perspex electrode to treat various contours of the face and body, when applied to the surface of the skin, a mild electrical current pass through a neon, or argon gas filled electrode, causing it to emit a subtle glow neon red/orange or violet/blue and buzzing noise. During the high frequency treatment, enriched oxygen molecules are produced that create an anti-bacterial action and a “natural” thermal tissue warming. This reaction helps blood vessels push away toxins, while the skin cells are enriched with nutrients. This in turn creates an increase in blood circulation and cell renewal that supports increased levels of collagen and elastin. The skin is left feeling instantly energized and noticeably softer after just one treatment. High frequency has proven to be effective on almost any skin lesion from acne and burns, to waxing procedures and cold sores.
