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.

There is provided a method of manufacturing a cutting element for use in a hair cutting device, the cutting element comprising an optical waveguide, the method comprising providing a preform for an optical waveguide, the preform comprising a core and an outer layer, wherein the outer layer is arranged around the core along the length of the core; forming a shaped preform by removing a portion of the outer layer along the length of the core to expose part of the core, wherein a remaining portion of the outer layer is a support structure for the core; heating the shaped preform; and pulling the shaped preform in the direction of the axis of the core to reduce the cross-section of the shaped preform and form the optical waveguide. Also provided is a cutting element manufactured according to the above method and a cutting element for use in a hair cutting device, the cutting element comprising an optical waveguide comprising a core and a support structure, wherein the support structure contacts the core along the length of the core to support the core, and wherein part of the core is exposed along the length of the core to form a cutting face for contacting hair. The thickness of the support structure tapers linearly or non-linearly from a thin side at which the support structure contacts the core to a thick side.

A shaving razor cartridge includes a housing and at least one razor blade. The housing extends between a front and rear end and defines an overall width. The housing includes a blade support portion and a housing portion. The blade support portion is positioned between the front and rear ends and includes a cap and a guard spaced from the cap. The handle interface portion is positioned between the front and rear ends and includes a front and rear wall. The front wall includes lower and interior surfaces. The rear wall includes a lower surface, a central portion, a first distal portion, and a second distal portion. The central, first distal and second portions each include respective interior surfaces. The at least one razor blade is disposed in the blade support portion. Each of the first distal portion and the second distal portion extends from the central portion.

A shaving razor handle includes a main body, a pair of arms extending from the main body, and a pivoting head that extends between an upper end and a lower end. The pivoting head includes a base member and a biasing member. The base member is pivotally coupled with the pair of arms to facilitate pivoting of the pivoting head about a pivot axis between a home position and a fully pivoted position. The base member includes a front wall and a rear wall. The front wall includes a first vertical height. The rear wall includes a second vertical height. The biasing member is operably coupled with the main body and is configured to bias the pivoting head into the home position. The first vertical height is less than the second vertical height.
