Plasma pen.

What the gurus are saying

Controlling burn depth to avoid scarring is the core concern dermatologists flag, since the plasma pen offers no reliable way to stop the energy once it penetrates the skin. Beyond that, the lack of training standards means untrained people are performing the procedure on themselves and others, which adds real safety risk. One dermatologist noted the device does coagulate tissue and stop bleeding, but stressed that any mole removed this way must be sent for pathology testing to rule out skin cancer, and emphasized this is not a procedure to attempt at home.
