Also called glycerol or glycerine; it is present in all natural lipids (fats), whether animal or vegetable. Glycerin works because of its ability to attract water from the environment and from the lower layers of skin (dermis) increasing the amount of water on the surface layers of skin.

In that respect it is one of the many substances in skin that help maintain the outer barrier and prevent dryness or scaling.
