Portrait plasma is a thermal energy-based treatment that stimulates the skin’s collagen and elastin production to rejuvenate the skin from the inside. A special handpiece is waved over the areas to be treated without direct contact with the skin. This delivers millisecond pulses of nitrogen-based plasma to the skin’s surface and causes a controlled heating of the skin's tissues. Portrait plasma leaves the skin's surface intact and the preserved outer layers of the skin serve as a protective dressing until new skin grows.
