Abstract

See full text

The invention relates to a device (100) for RF skin treatment comprising an outer electrode (2) arranged on an operational side (15) of the device. The outer electrode has an annular or equilateral polygonal shape. An inner electrode (1) is arranged at a center of the outer electrode and is surrounded by the outer electrode. An RF generator (21) is arranged to supply an RF treatment voltage between the inner electrode (1) and the outer electrode (2). A skin contact surface of the inner electrode has a largest cross-sectional dimension in a range of 200-500 μm, and the RF treatment voltage is less than 50 V. The invention provides a device with improved safety in that it enables the creation of non-ablative fractionated skin lesions, particularly using a relatively low RF treatment voltage for treating the skin as compared to known devices and without the necessity of a feedback or monitoring system.
