What is High Frequency?
High frequency is an advanced facial device that consists of a glass electrode that houses either neon gas or argon gas. A mild electrical current flows through the neon or argon as the electrode is attached to your skin, triggering a reaction that produces both red and violet rays (argon and neon).
As opposed to many other energy-based devices, the current doesn't pass through your skin. It is this light that treats various skin concerns: violet light is used to treat acne and blemishes, and red light to treat aging skin. After studying the effects of light therapy for years, it is evident that either light is effective for treating a number of skin concerns.
