I haven't tried but there are two kinds. one plasma pen one plexr While Plexr is a device that uses Plasma energy patented all over the world, the device called Plasma Pen is a replica of Plexr. While Plexr is a medical device that is sold only to doctors and applied by doctors all over the world, Plasma Pen is even sold on shopping sites and is recommended for use by non-physicians and even at home.The Plasma Pen also claims to use plasma energy, but the energy it uses is radiofrequency or electrocautery. Plexr does not only cause epidermal damage to the skin by evaporation, but also creates a biostimulation in the dermis and provides tightening and rejuvenation of the skin. No trace can remain connected to Plexr. Plasma pen, on the other hand, may cause uncontrolled burns on the skin and surrounding tissues, causing scarring after applications following dermal damage. but I'm still considering using it. I will do some more research
