What is high frequency ?

“High frequency facial machines work in conjunction with high frequency electrodes which are made of clear tempered glass and come in a variety different shapes and sizes to facilitate the treatment of various contours of the face and body. When the high frequency electrode is firmly inserted into the high frequency hand piece, a gentle alternating electrical current is generated by the high frequency machine which then passes through the attached glass electrode upon contact with the skin. This contact ignites the inert gas within the electrode which produces healing electrical light energy and unstable oxygen which instantly converts into purifying ozone. In other words, when mixed with the air outside of the electrode, the electrical current infuses the skin with rejuvenating oxygen molecules and a therapeutic zapping or tingling sensation is experienced.” Joyfulyoga
