Liquid glycerin is a thick, clear liquid found in many cosmetics and personal care products such as soaps. Glycerin is a natural solvent and is hygroscopic, meaning it draws moisture from the air. This hygroscopic quality makes glycerin an excellent moisturizer for human skin. Unlike many lotions and creams commonly used as moisturizers, glycerin helps the skin attract its own moisture. Using glycerin during hair removal through shaving is one way to benefit from its skin-moisturizing properties.

Wipe area to be shaved (such as face or legs) with a clean, damp washcloth.

Use fingers or washcloth to thoroughly wet skin. Glycerin easily dissolves in water, so make sure the area is moist enough so the glycerin spreads evenly over skin.

Put a small amount of liquid glycerin into your palm, then rub it between hands. The amount of glycerin needed will depend on the size of the area to be shaved.

Using fingertips, apply glycerin to the area you plan to shave by rubbing in a circular motion. Lather the entire area so it is covered with a thick layer of glycerin. Add more water with your fingertips if you are having trouble spreading the solution.

Using a shaving razor, shave against the grain of the hair. For example, when shaving legs, place the razor gently against the skin, starting at the ankle, and run it upward toward the knee.

Rinse remaining glycerin from skin using warm water and pat dry with a clean, dry towel.
