Abstract
The present invention relates to an apparatus for fractional treatment of skin tissue of a patient comprising a handpiece, at least one first electrode and at least one second electrode, arranged on a base plate for applying radio frequency energy, to at least one layer of the skin, wherein the apparatus is adapted to apply electrical energy to the skin tissue with a first pulse and a second pulse following the first pulse, with the first pulse being a low energy level pulse and the second pulse being a high energy level pulse having a higher energy level than the low energy level pulse.
