Which term describes the alternating, interrupting electric current used for certain facial treatments?

The term that describes the alternating, interrupting electric current used for certain facial treatments is faradic. This type of current is characterized by its ability to stimulate muscle contractions, which can enhance treatment outcomes for various esthetic procedures. Faradic current is primarily used in electrotherapy applications, where its alternating nature aids in muscle toning and improving circulation in the skin.

In contrast, galvanic current is a continuous direct current used mainly for chemical treatments and iontophoresis, where substances are introduced into the skin, but it does not have the same stimulating effect on muscles as faradic current. Tesla current, on the other hand, refers to high-frequency alternating current, often used for sparking and thermal applications rather than the direct muscular stimulation associated with faradic currents. Volt is a unit of measurement for electric potential, not a specific type of current or treatment method.

Understanding these distinctions highlights why faradic is the correct choice in this context.
