a plasma ozone meter can be used in all parts. the epidermis did not have any wounds after the plasma ozone instrument was operated. gas aterials apply energy. the ionization generated by electrons changes to a gas state. at this time, the applied energy includes various types such as heat, alternating current, direct current, and rf. in the case of plasma, a direct current is used as an energy source. the skin elasticity after the operation of the plasma ozone meter becomes better due to the production of new collagen. no pain, no scarring, no bleeding, no wounds, non-invasive operation, more convenient operation, safer and more effective..syi
