Microcurrent treatments are characterized by their ability to provide muscle stimulation. This form of therapy uses low-level electrical currents that are similar to the body’s own natural electrical impulses. When applied to the skin, microcurrent can selectively target and stimulate facial muscles, promoting toning and lifting effects. This stimulation also encourages circulation and collagen production, leading to improved skin texture and appearance.

The other options do not accurately characterize microcurrent treatments: they typically do not produce a warming sensation, as they are designed to be gentle and have a tingling sensation rather than warmth. While they involve electrical currents, they do not utilize high-frequency currents; that characteristic pertains to a different type of treatment. Additionally, a basic understanding of electrical principles can be beneficial when performing such treatments, contrary to the notion that no electrical understanding is required. Overall, the muscle stimulation feature represents the key aspect of microcurrent treatments.
