Abstract
A system and method for treating the skin by heating at least one discrete skin volume, comprising at least one treatment tip reversibly connectable to at least one applicator. The treatment tip comprises one or more electrodes, with the electrodes having one or more spaced apart protruding conducting elements. The protruding conducting elements are characterized by dimensions of height A and hypotenuse B, where the ratio A/B is in a predetermined range, and the protruding conducting elements penetrate the skin surface at discrete locations. The electrodes are configured to apply energy to skin volumes around the discrete locations so as to heat the skin volumes. The applicator comprises an energy generator configured to apply energy to the skin volumes by means of the electrodes and the spaced apart protruding conducting elements.
