Lanolin is a special kind of wax derived from sheep's wool. It has a significant and long-lasting effect on skin smoothness. It also helps prevent water loss through the skin, which helps keep the skin from drying out. It has been shown effective in helping to heal dryness, flaking, scaling, and cracking of the skin, and helps relieve pain and itching.
