1. A skin treatment device comprising:
a plurality of electrodes configured to directly contact a skin surface of a user's skin non-invasively, wherein at least one of the electrodes at least partly encloses another at least one of the electrodes;
a plurality of radio frequency (RF) generators, arranged to deliver RF energy to the skin via the electrodes, wherein the at least one of the electrodes and the another at least one of the electrodes enclosed thereby—are connected to different RF generators; and
a control unit arranged to control RF energy delivery by the RF generators through the electrodes to the skin according to a specified transmission plan comprising controlling relative phases between the RF generators and relative electrode polarities to yield at least one pair of adjacent electrodes with the same polarity to concentrate the delivered RF energy to a specified skin volume at a predetermined depth below the skin surface,
wherein the specified transmission plan is configured to elevate a temperature of the specified skin volume with respect to the skin surface while keeping the skin surface below a specified temperature threshold.
