100% Natural Lanolin in 4 oz. container. Lanolin is a byproduct from sheep and a renewable resource. It is a safe and friendly product perfect for a wide range of personal skin care applications, protecting the skin against drying effects of wind and cold; it helps with healing the skin just as it does for the sheep. We've found these effects to be true for ourselves and our friends - it may be the same for you! In a scientific study of 825,000 people, only 6 were found to be allergic to lanolin. Bottled and packaged by Cestari Sheep & Wool Company.
