No Plexr is not a laser. They have differing operating principles. Laser uses photons to treat, vaporise and modify tissues. It absorbs energy by the tissues in a different way.
Plexr is a Micro Plasma Generator. As a result there is No Thermal damage and an absence of necrotic tissue. Plexr is clinically proven to shrink the epidermal layer but NOT damage the basal membrane (basal lamina). In addition safety glasses are not required.
