摘要：
The invention relates to a device (100) for radio frequency (RF) skin treatment comprising an active electrode (1 31) arranged on an operational side (15) of the device and having a first skin contact surface for electrical contact with a skin of a user during use. The device further comprises a return electrode (2 32) arranged on the operational side (15) of the device and having a second skin contact surface for electrical contact with the skin of the user during use. The second skin contact surface is at least five times larger than the first skin contact surface. An RF generator (21) is arranged to supply an RF treatment voltage between the active electrode and the return electrode when the active electrode and the return electrode are in electrical contact with the skin so as to heat the skin below the active electrode. A coupling member (45 46 61 62 402 403) is adapted to be arranged on the first skin contact surface and comprises an electrically conductive material to improve the electrical coupling of the active electrode to the skin surface. The coupling member comprises a first layer (45 61 403) of a first electrically conductive material adapted to be arranged on the first skin contact surface and a second layer (46 62 402) of a second electrically conductive material different from the first material arranged on the first layer on a side of the first layer remote from the first skin contact surface wherein the first layer has a thickness in a range from 10 m to 100 m and the first material has a modulus of elasticity of at least 100 kPa and wherein the second layer has a thickness of 10 m or less and the second material has a viscosity of 1 000 CPS or less.
