Shaving creams, soaps, gels, foams and oils provide lubrication between the razor and skin. Soaps and creams designed for a shaving brush are worked into a lather with water; brushless creams, ready-made foams and suitable gels or oils can be applied without a brush. Choose by your preferred preparation and the visibility you need: a transparent gel can help when shaping edges, while lather covers the shaving area; check whether the specific formula lathers and how it should be applied.
