There are 4 states of matter; solid, liquid, gas then plasma!
Advanced plasma technology
Plasma is where the gaseous state has been ionised by very high temperatures and electricity. The Plasma BT machine generates plasma in the minuscule air gap between a tiny needle and your skin. This causes pinprick size burns and sterilises the area. It also changes the positive and negative charges in the skin cell membrane, aiding regeneration of new tighter skin and thereby increasing the formation of collagen and elastin.
