From the Manufacturer's Label:
Protects chapped Skin
Condition: Skin in need of protection from wind burn and environmental factors.
Solution: Pure Lanolin is a powerful, natural moisturizer that can promote the smoothness and translucency associated with healthy, youthful skin. Derived from the wool of sheep, lanolin is remarkably close to our own natural skin oils and has a texture that is similar to petroleum jelly. It is perfect for use on very dry, rough or chapped skin.
