Glycerin

Also called glycerol it is present in all natural lipids (fats), whether animal or vegetable. It can be derived from natural substances by hydrolysis of fats, coconut and palm oil, and by fermentation of sugars. Glycerin is a humectant and extremely hygroscopic, meaning it readily absorbs water from other sources. So, in part, 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 in the surface layers of skin. Another aspect of glycerin’s benefit is that it is a skin-identical ingredient, meaning it is a substance found naturally in skin. In that respect it is one of the many substances in skin that help maintain the outer barrier and prevent dryness or scaling.
