What does microcurrent primarily mimic to stimulate muscles?

Microcurrent primarily mimics the body's natural impulses to stimulate muscles. This low-level electrical current operates at a frequency that closely resembles the electrical signals naturally produced by the body's cells. This similarity allows microcurrent therapy to facilitate muscle contraction and promote overall muscle tone by enhancing the natural communication between nerves and muscles. As a result, microcurrent is often used in facial treatments to lift and tighten the skin by encouraging the muscles underneath to engage and respond as they would with typical body functions. By closely imitating the body's intrinsic signals, microcurrent therapy can effectively enhance cellular repair and rejuvenate tissues.
