1. A system for selectively treating a plurality of discrete skin volumes, the system comprising:
- a plurality of protruding conducting elements configured to contact a plurality of discrete skin locations, wherein the plurality of protruding conducting elements are further configured for connection to an RF voltage source for applying a voltage to the plurality of protruding conducting elements to energize the plurality of protruding conducting elements, and wherein the plurality of protruding conducting elements are further configured such that, when the plurality of protruding conducting elements are in contact with the discrete skin locations and energized, the plurality of protruding conducting elements cause selective heating of the plurality of discrete skin volumes adjacent to the plurality of discrete skin locations; and
a cooling element configured to maintain the plurality of discrete skin locations below a coagulation temperature when the plurality of protruding conducting elements are in contact with the plurality of discrete skin locations, the cooling element comprising at least one tube between protruding conducting elements and at least a coolant circulating therethrough.

Abstract
A system and method for simultaneously heating a plurality of discrete skin volumes to a coagulation temperature. The system comprises an applicator containing an electrode having a plurality of spaced apart protruding conducting elements configured to contact the skin surface at a plurality of discrete locations. A controller applies a voltage to the electrode so as to simultaneously heat a plurality of skin volumes to a coagulation temperature when the applicator is applied to the skin surface.
