RET high-frequency fat dissolving principle: slimming, shaping, slimming, fat dissolving instrument,-coating? Two electrodes are attached to the 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 the local tissue (the deep part where visceral fat cannot work through C.E.T). Effectively solve the problem of deep parts of local tissues (visceral fat, deep parts where C.E.T can't achieve the effect).
