O'Keeffe's GRGOKWH is a unique formula designed for dry, cracking hands. Dry hands tend to occur either from the air temperature or from working in the Engineering and Automotive industry, where you would be working with different types of oils and lubricants. When the skin begins to get dry it naturally starts peeling. This damages the skin barrier. Once the barrier is broken it leads to an increased water loss which creates the dry skin. O'keefe has created a formula that will help even the toughest of hands. It not only protects the skin by creating a protective barrier but it also draws the moisture back into the skin. Supplied as a single unit.
