Microcurrent therapy works primarily by mimicking the way the brain relays messages to the muscles. This process involves the transmission of electrical signals that stimulate muscle contractions, promoting tissue repair and improving muscle tone. Microcurrent devices utilize a low-level electrical current that is similar to the body's natural bioelectrical signals, facilitating better communication between the muscles and the nervous system.

The effectiveness of microcurrent therapy is notable in its ability to enhance the body's natural healing processes, reduce inflammation, and promote cellular activity. This approach is particularly useful in aesthetics for skin rejuvenation, muscle toning, and overall revitalization. It aligns well with the physiological processes of the body’s own mechanisms for repairing and maintaining muscle and skin health.

The other choices, while they describe important physiological functions, do not reflect the specific mechanism of action that microcurrent therapy is based on. The heart pumping blood, nutrient absorption by the skin, and gas exchange in the lungs are distinct processes that do not directly relate to the electrical signaling and muscle interaction that microcurrent therapy aims to replicate.
