Shaving creams, soaps, gels, foams and oils are different formats that create a lubricating layer between the razor and the skin. Hard soaps and many creams are lathered with a shaving brush, while brushless creams, gels, foams and oils are applied directly to the skin; transparent gels and oils keep the shaving area visible, whereas creams, soaps and foams cover it. Choose according to whether you want to use a brush, how much preparation and visibility you prefer, and the manufacturer’s stated suitability for your skin type.
