What do faradic devices primarily do?

Faradic devices primarily function to visibly contract muscles through the use of electrical currents. These devices utilize alternating current to stimulate the nerves and induce muscle contractions, which can enhance muscle tone and improve overall muscle strength. This muscle contraction mimics the natural movement that occurs during physical exercise, which can be particularly beneficial for those seeking to improve their muscle definition or rehabilitate muscle after injury.

While options related to enhancing skin hydration, improving blood circulation, and reducing pigmentation may have indirect benefits from muscle stimulation or overall electrical treatment, they are not the primary functions of faradic devices. Therefore, the focus on muscle contraction is what distinguishes faradic devices from other electrotherapy devices used in aesthetic and therapeutic treatments.
