High Frequency Current is also known as what?

High frequency current is known as radiant current. This form of current is characterized by its ability to produce thermal and physiological effects when applied to the skin. It operates at a very high frequency and is commonly used in various esthetic treatments, particularly for its antibacterial properties and its capability to stimulate circulation, promote healing, and improve skin texture.

In contrast, direct current refers to a steady flow of electrical charge in one direction, which is different from the alternating nature of high frequency. Galvanic current is a type of direct current used primarily for iontophoresis and product penetration, while test current is a term that is less standardized and does not relate to high frequency. Radiant current, the term that correctly describes high frequency current, reflects its ability to generate radiant heat and electromagnetic waves effective in skin treatments.
