Glycerin, which is also called glycerol, is polyol compound. It is a monomeric polyol or an alcohol that contains three hydroxyl groups. It is an integral component of triglycerides. It is colorless and odorless, and has a high viscosity. It has a sweet taste. It is used in several pharmaceutical preparations such as cough syrups, tinctures, and elixir. It is also used in creams and ointments as a preservative or a softening agent. It is also used in skin care products such as soaps, lotions, and body scrubs due to its ability to retain moisture.

► As a Humectant
A humectant is a substance that facilitates water retention. These substances are often added to other products in order to help them retain moisture. Glycerin also acts like a humectant for the skin. It is hygroscopic in nature. It has the ability to attract or draw water from air. Being a humectant, it attracts moisture from the atmosphere into the skin. Water loss due to evaporation is also minimized. This keeps the skin moisturized and nourished.
► Cell Maturation
It is believed that glycerol may play a role in cell maturation. Research has revealed that glycerol is transported through aquaporin 3, a channel expressed in skin cells. The interaction between glycerol and an enzyme called phospholipase D is believed facilitate skin cell maturation. A study was conducted on mice that were genetically modified so that they didn't have the channels through which glycerol is transported. When glycerol was applied topically or given orally to them, their skin problems were alleviated to a great extent.
