A handheld plasma pen that fires ionised gas at damaged or unhealthy skin could be used to treat people with a range of conditions, from acne to diabetes. The plasma treatment, which is non-invasive, could be used to replace some surgical procedures, and can significantly reduce scarring
How does a plasma pen work?
Plasma Pen works on the principle of ionized gas in the air. At the right distance from the skin (treated area), oxygen and nitrogen are mixed, and the electrostatic energy produces the plasmatic effusion, which discharges on the skin with thermals. … The Plasma energy is directed through a precise tip of the hand piece.
