Hot Plasma-Technology (~70 °C)
Strong electrical pulses are passed through a thin nail (e.g., plasma-pen). The contact with the air at the end of the nail causes a flash. The resulting effect is called the hot plasma cord.
With this thin needle superficial skin can be burned.
The resulting crust falls off automatically within a few days. At each burning point, cleansing of the skin occurs. This reduces the skin surface.
After the healing process a tightening effect occurs.
