During the treatment, a handheld device called a Plasma Pen emits a plasma plume that causes a controlled, superficial burn to the epidermis. The plasma plume is a very small electrical arc which is formed through the ionisation of atmospheric gasses to stimulate the instant contraction and tightening of the skin. The plume evaporates and leaves a very small brown mark. The controlled damage process instantly shrinks the targeted skin, causing the skin tissue to retract and tighten giving you a more youthful looking skin.
