Glycerin is a chemical compound used in skin care products and cosmetics as a humectant, that is, a skin conditioning agent that increases water content of the top layers of the skin by drawing moisture from the surrounding air. Glycerin also acts as a lubricant on the skin surface, which gives the skin a soft and smooth appearance 1.
In oral solutions, glycerin is used as a solvent, sweetening agent, antimicrobial preservative, and viscosity-increasing agent. It can also be used in film coatings for tablets.1.
Glycerin is included in the U.S. Food and Drug Administration (FDA) Inactive Ingredients Guide as safe to use in the amounts present in our products.
