Glycerin – sometimes spelt `Glycerine` and also known as Glycerol – is a humectant which means it helps attract water and keep it in the skin. It is a very effective moisturizer that smooths dry skin and gives it long-lasting moisturization and care. It is both colorless and odorless.

Urea is also produced naturally by the skin and is part of the essential Natural Moisturizing Factor (NMF) which regulates skin’s moisture content. Urea is hygroscopic, which means it is able to bind moisture into the outermost layer of skin, thus relieves itching and roughness, helping  to  fight  dry  skin symptoms. It is also keratolytic, meaning it improves natural exfoliation and soothes and smoothes the skin’s surface. As a substance produced naturally by the skin, Urea is well-tolerated even by dry and sensitive skin. Because all of these effects and very good study data, Urea is the gold standard in treating of dry skin.*
