MICROCURRENT THERAPY How it works. Blumene Face Pro™ utlizes microcurrent therapy. These are low-grade electrical currents that mimic the body's natural ionic flow to safely tone, lift, and contour the neck muscles. The Microcurrent causes the muscles to contract, re-training them to maintain their shape and reduce sagging. Microcurrent also promotes collagen and elastin production, two key structural proteins which are essential for keeping the skin firm and supple, and giving it a youthful glow.
