PlasmaMD treatment is highly controlled and targeted to a specific treatment area. This hand-held, pen-like device is held above the skin’s surface during treatment, from up to one millimeter away. PlasmaMD never comes into contact with the skin. Rather, it works by emitting plasma energy, which reacts with the naturally occurring nitrogen molecules in the air. The reaction between the plasma energy and the nitrogen molecules creates an energetic burst in the shape of an arc, creating a micro-injury in the top layer of skin as well as heating up the dermis, where it causes collagen fibers to contract.
