Urea (also known as Carbamide) is produced naturally by the skin and is an essential Natural Moisturizing Factor (NMF) regulating skin’s moisture content. Urea is hygroscopic, which means it is able to bind moisture in to the outermost layer of skin. It is also keratolytic, meaning it breaks down the connections between dead skin cells, and has anti-itch and anti-microbial properties. As a result, it improves natural exfoliation and soothes and smooths the skin’s surface. As a substance produced naturally by the skin, Urea is well-tolerated even by dry and sensitive skin.
