The most effective weight-loss device is the energy-gathering weight-loss device. The principle is to soften, contract, decompose and burn the deep fat by generating biological thermal effect. Especially for intractable muscle fat mixed fat (commonly known as pork belly type) and visceral hidden fat, it has incomparable effect with other instruments. At the same time, ultra-microwave can raise the temperature of deep tissues of human body, activate lymph nodes and dilate lymphatic capillaries, and take away decomposed fat droplets and other metabolites through accelerated flowing lymph. Negative pressure and bionic micro-current have extraordinary effects on tightening and shaping, lifting hips and abdomen and restoring muscle elasticity.
