A small electrical arc forms between the device tip and skin surface.
A small plasma arc creates controlled points of superficial injury to stimulate tightening and repair.
Also known as:

Improve crepey skin: Eyes & Brows, Neck, Chest & Collar, Hands, Arms, Thighs & Buttocks.
A small device creates an electrical arc between its tip and the skin without a conventional needle entering it. The arc makes tiny points of surface injury, leading to scabs and a healing response. As the area repairs, skin may contract or remodel. The treatment can cause pigment changes or scars, so the setting and operator matter.

A small electrical arc forms between the device tip and skin surface.
It creates spaced, tiny points of surface injury that form scabs.
As those spots heal, some skin contraction or remodelling may occur.
