Proraso Shaving Soap Shea Butter doesn’t just take such natural ingredients for their entrancing aroma; all are in fact chosen for their benefits to skin during and after the shave. The chief addition of Shea Butter helps combat the tightening and drying of skin during shaving, increasing elasticity and softening in the process. Glycerine forms the base of the soap, calming and soothing throughout the shave for the smoothest experience possible with true barber quality. The real difference is in how it’s made; the world renowned ‘hot process’ permanently setting the soap apart by maturing and concentrating it ahead of application.
