1EMS micro current, stimulate ATP production, stimulate collagen activity, while assisting radio frequency, it can lift and tighten skin. 2RF multipolar radio frequency technology, focus on the dermis, restimulate epidermal skin, stimulate collagen regeneration, skin restores elasticity. 3635nm red light penetrates deep into the skin to promote skin microcirculation, repair damaged barrier, improve gloss. 4Temperature sensing, the 3 golden bars of the contact detect the skin temperature in all directions, and the radio frequency will be automatically stopped when it exceeds 43C to ensure skin safety. 53 gears design, suitable for all skin types, easy to adjust. Skin sensor, it emits red light when it fits the skin to avoid accidental irradiation of red light.
