## Abstract

The invention relates to a radio-frequency (RF) device for non-ablative treatment of skin and subcutaneous fat using applicator with multiple RF delivering elements.

## Claims

### Claim 1

A device comprising:
a face applicator comprising a face securing member configured to secure said face applicator to at least one cheek of a subject; and
radio-frequency (RF) elements coupled to said face applicator and coupled to an RF generator; and
impedance and temperature measurement sensors coupled to said RF generator.

### Claim 2 (depends on 1)

The device according to claim 1, wherein said face securing member comprises symmetrical portions for securing said face applicator to both cheeks of the subject.

### Claim 3 (depends on 1)

The device according to claim 1, wherein said RF elements comprise a central electrode which has a polarity and side electrodes which have a polarity opposite to said polarity of said central electrode.

### Claim 4 (depends on 3)

The device according to claim 3, wherein a treatment area of said central electrode is identical to a total treatment area of said side electrodes.
