Skin treatment personal care device and method of manufacture
A skin treatment personal care with a handle having a gripping portion at one end and a head portion at an opposing end. The head portion includes a heat dissipating housing having a top surface and defines a pocket. The heat dissipating housing is made of a material having a thermal diffusivity greater than 10 W/m K. A light emitting diode adapted to provide one or more skin benefits is positioned within in the pocket. A window forms a water tight seal covering the LED.
