Abstract

A shaving razor system with a heating element for transferring heat during a shaving stroke. The heating element has a skin contacting surface. An insulating member for delivering heat to the heating element has a plurality of spaced apart thermal sensors are mounted to the insulating member and positioned below the skin contacting surface. An electrical circuit is configured to deliver energy to the insulating member. The electrical circuit has a control circuit for temperature regulation. A power source is in communication with the electrical circuit. The thermal sensors measure the temperature of the heating element and are in communication with the control circuit.
