Abstract

A skin contact sensor and method are disclosed in a dermatologic treatment device that includes a skin contacting structure, a treatment source capable of being activated to supply a dermatologic treatment through the skin contacting structure. A plurality of sensors are positioned around a periphery of the skin contacting structure, and control circuitry coupled to the plurality of sensors inhibits activation of the dermatologic treatment device unless contact with a compliant surface is sensed. Another embodiment employs a single sensor which is positioned distal to the skin contacting structure so that a non-compliant surface in contact with the skin contacting structure is unable to activate the single sensor.
