Claim Text:
1. A method of treating a skin surface with RF energy, comprising: applying to the skin surface a first semiconductive cap disposed on a first distal end of a first electrode; applying to the skin surface a second semiconductive cap disposed on a second distal end of a second electrode; and delivering RF energy from the first electrode and the second electrode through the first semiconductive cap and the second semiconductive cap, respectively, through the skin surface, wherein a waveguide is disposed between the first electrode and the second electrode to deliver optical radiation, wherein an electrically insulating region having a triangular vertical cross-section is disposed between a surface of the waveguide and one of the semiconductive caps, and wherein each of the semiconductive caps has an electrical conductivity matched or substantially matched to the skin's electrical conductivity.
