Lanolin oil is a secretion from sheep’s skin. The purpose of lanolin is to condition and protect sheep’s wool. Lanolin oil is extracted by putting sheep’s wool through a centrifuge machine that separates the oil from other chemicals and debris. The process is performed after the sheep is sheared so the extraction of lanolin causes no harm to sheep.
Lanolin oil is known as an emollient, which means it helps soothe dry or dehydrated skin. Lanolin is classified as an emollient and an occlusive moisturizer, which means it has the ability to slow water loss from the skin, and reduce the appearance of fine lines and wrinkles.
