Which of the following best describes electrical energy treatments?

Electrical energy treatments primarily involve advanced techniques that utilize various forms of energy, such as sound or light, to achieve cosmetic or therapeutic effects on the skin. This can include methods like microcurrent therapy, LED light treatments, or ultrasound, all aimed at rejuvenating the skin, improving its appearance, or treating specific skin conditions. These treatments are distinct from basic facials, which typically rely on creams and oils, and do not necessitate hospitalization. Additionally, they are not limited to traditional methods of facial care, but rather incorporate cutting-edge technologies to enhance results. As such, the description of advanced techniques using sound or light energy aligns perfectly with the nature of electrical energy treatments.
