Abstract
A coupling arrangement including a coupling member arranged on a skin contact surface of an electrode of a radio-frequency (RF) skin treatment device for electrically coupling the electrode to a user's skin. The coupling member includes a first layer and a second layer. The first layer has a first electrically conductive material configured to be arranged on the skin contact surface via one side of the first layer. The second layer has a second (different) electrically conductive material arranged on the first layer, on an opposite side of the first layer. The first layer has a thickness in a range from 10 μm to 100 μm, and the first electrically conductive material has a modulus of elasticity of at least 100 kPa. The second layer has a thickness of 10 μm or less, and the second electrically conductive material has a viscosity of 1,000 CPS or less.
