The noninvasive treatment involves zapping your face with tiny electrical currents to stimulate, tone and tighten facial muscles. "It's been used for facial paralysis for about 70 years, and it's a common use for other areas of the body. Next, the aesthetician would use two metal prongs to apply electrical currents to the skin's surface, stimulating the facial muscles underneath. They're delivering currents back and forth," Bays said while performing a microcurrent facial procedure on a patient at the Plastic Surgery Centre of Atlanta in early February. For instance, when people have facial paralysis or Bell's palsy, they would see a physical therapist to learn how to move and retrain certain facial muscles, Knott said.
