O'Keeffe's® Working Hands is a unique formulation of moisturizing ingredients guaranteed to improve the health of your hands. This revolutionary conditioner uses key ingredients to assist in healing of dry damaged skin. First is glycerin, which draws water into the skin and helps it retain moisture, a step necessary for healing. Next is allantoin, derived from the comfrey, which facilitates the removal of dead skin cells to prepare your skin for better penetration and absorption of moisturizing ingredients. The most valuable tool we all have is our hands -- so you better take care of them.
