You should wash your face before you shave. Cleansers help soften your beard. Change razors or blades frequently. A dull blade can irritate your skin and cause rashes. Apply shaving cream or gel (without alcohol) on your face. The shaving cream or gel produces lather, which helps protect the skin as the razor cuts the hair. Go with the grain of your hair, not against it. For most guys, whiskers on the face grow down. So shaving downward on the face removes most of the hair. Shaving against the grain (or upward) can cause rashes or red bumps. It’s very important to shave slowly and gently. Let the razor blade do the work. Don’t push down too hard with the razor. t’s better to go over a part of the skin twice -- lightly -- than to press down hard. Use soft, short strokes on your jaw and chin.
After you shave, you should use a light moisturizer can soothe skin and cut down on razor burn. Don't use aftershave.
