RET high-frequency fat dissolving principle: weight loss, slimming, shaping, slimming, fat dissolving instrument,-two electrodes are attached to the coated metal electrode, so that the tissue between the two electrodes generates bio-heat, and the tissue between the electrodes reacts, so that the energy can reach the deep part of local tissue (the deep part where visceral fat cannot be effective in a C.E.T way). Effectively solve the problem of deep parts of local tissues (visceral fat, deep parts where C.E.T can't achieve the effect).
