Abstract: A system advantageously includes a handheld device with a body with two pairs of electrodes mounted or carried by respective arms extending from the handheld body, where at least one pair of arms is movable (e.g., pivotal, rotatable) with respect the body and hence with respect to the other pair of arms. The moveable arms can be biased toward an un-rotated position or orientation, applying a tension to bodily tissue via the moveable arms when rotated out of the un-rotated position or orientation. The system optionally includes a circuit integral to the handheld device, or integral to a console to which the handheld device is coupled, the apparatus operable to deliver microcurrent signals via two separate channels and via interferential signals between the two separate channels, to facilitate kinesiology facial sculpting application in conjunction with the delivery of microcurrent signals, which can be employed in cosmetic applications.
