High frequency machines are handheld electrical devices used for anti-bacterial and treatment for oily and acne-prone skin. High frequency machine has replaceable glass wand with gas and coil inside it. The internal coil converts electrical current into energy that heats up neon or argon gas inside a tube. When the esthetician places the HF wand on the skin, a thin sterile ozone layer is created. This treatment helps to soothe the skin, reduces irritation, inflammation, and helps to treat acne, and other skin conditions.
