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. Faradic current is characterized by its ability to induce muscle contractions, which can be beneficial in facial treatments aimed at improving muscle tone and promoting circulation. It operates at a frequency that allows the current to stimulate the nerves, leading to these effects.

Galvanic current, in contrast, is a direct current that is not alternating and is used primarily for iontophoresis and desincrustation. Tesla current, also known as high-frequency current, is used for various treatments as well but operates at much higher frequencies and is not characterized by an interrupting current. Volt is a measure of electrical potential and does not describe a type of current per se.

Understanding these distinctions helps clarify why Faradic is the correct term for an alternating, interrupting current used specifically for facial treatments.
