High frequency electric wave launched by RF beauty equipment can stimulates anion and cation in the cell to generate heat by friction ,accelerates blood circulation of dermis and subcutaneous tissue, stimulates collagen rebirth and reconstruction, repairs aging and damaged collagen ,in order to tighten skin and reduce wrinkle

The two electrodes of RF beauty equipment  can separately set in each side of body. Only one electrode in the handle (insulating on the surface), in view of promote the depth launched by handle electrode and the deepest is above 20mm. There is no electricity between handle electrode and skin, its totally depends on launching electric wave. So the depth care really come true.
