EMS Gynecomastia Reduction Massager can help reduce swelling and expedite the healing process of injured or damaged tissue. It can also help slow down and reduce excessive growth of breast tissue that causes Gynecomastia. EMS uses electrical impulses that stimulate the nerves and engage muscle fibers. The device mimics the brain: in order to activate a muscle, the brain sends shocks to the neurons in the muscle group. These currents cause the muscles to expand and contract, just like they might during usual exercise. Our massager's use of EMS helps to prevent atrophy and reduces inflammation, which are both very common symptoms of Gynecomastia. And EMS deals with these issues by channeling a low-frequency electrical current through muscle nerves and the connective tissue.
