Radiofrequency literally means radio transmission frequency (300 kHz~1,200 kHz). However, Radiofrequency in medical devices refers to Radiofrequency current, and unlike general commercial alternating current, it uses alternating current of 100 kHz to tens of MHz. In other words, treatment using Radiofrequency is a method of obtaining medical or cosmetic effects by applying Radiofrequency current to the biological tissues of the human body and using the frictional heat generated as ions in cells move between the anode and cathode.

When Radiofrequency current is passed through the human body, heat is generated in the tissues, which is called deep heat. When heat of an average of 38°C to 45°C is repeatedly and continuously delivered through deep heat, arteries and capillaries expand and metabolic function becomes active. In addition, it helps blood and lymph circulation, has a sterilizing effect due to high temperature, and induces the production of collagen in dermis. It also plays a role in loosening knotted muscle tissue, and is widely known to have excellent effects in obesity treatment, pore reduction, wrinkle removal, hair promotion, and pain relief.
