Abstract
A heat delivery element for a shaving razor with a face plate having a skin contacting surface and an opposing inner surface. A heater having a heater track is positioned between an upper dielectric layer and a lower dielectric layer. A heat dispersion layer having a lower surface directly contacts the inner surface of the face plate. An upper surface of the heat dispersion layer directly contacts the lower dielectric layer of the heater.
