1. A system for applying RF energy to aplurality of discrete regions of skin, said system comprising:
- an applicator comprising an electrode including flat parts and a plurality of protruding electrically conducting spaced apart pins terminated by sharp tips, the pins configured to penetrate throguh epidermis into the dermis and apply RF energy to one or more discrete tissue volumes that are completely located in the dermis, so as to heat the tissue volumes to a coagulation temperature;
a radio frequency energy source configured to apply radio frequency energy to the electrode with at least the plurality of protruding electrically conducting spaced apart pins to generate an electrical current in the dermis from the tips higher than from the flat parts of the electrode;
a control unit configured to allow input selected values of parameters of the RF energy to at least one located below skin tissue surface dermal tissue volume producing dermal tissue temperature increase to cause thermal collagen remodeling; and
tubes in flat regions between the protruding electrically conducting spaced apart pins for circulating a cooling fluid there through and cooling the electrode and the skin surface.

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.

6. A method for heating a plurality of discrete dermis volumes to a coagulation temperature, said method comprising:
-
applying to skin surface an applicator comprising at least one electrode including flat parts and a plurality of protruding electrically conducting spaced apart pins terminated by sharp tips, the tips configured to penetrate through epidermis into dermis reaching a plurality of discrete volumes located in dermis; applying a voltage to the at least one electrode with the plurality of protruding electrically conducting spaced apart pins to generate in the dermis an electrical current from the tips higher than from the flat parts of the electrode simultaneously heating a plurality of dermis volumes to a coagulation temperature; and cooling the electrode and the skin surface by circulating a cooling fluid through tubes in the flat parts between the protruding electrically conducting spaced apart pins.

12. A method for invasive collagen remodeling with reduced skin redness, the method comprising:
-
applying to the skin an electrode including flat parts and a plurality of spaced apart protruding conducting pins terminated by sharp tips; pressing the electrode such that protruding conducting pins terminated by sharp tips penetrate into the dermis; supplying RF voltage to the electrode and treating the skin simultaneously in a plurality of discrete skin volumes located in the dermis; cooling the electrode and the skin surface by circulating a cooling fluid through tubes in the flat parts between the protruding electrically conducting spaced apart pins; and wherein location of the plurality of discrete skin volumes located in the dermis reduces skin redness occurring at the treated regions of the skin.
