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.*

Healthy skin contains Natural Moisturizing Factors (NMFs) which attract and bind in water to the outermost layers of skin, helping to prevent it from drying out and becoming scaly and rough. The NMFs present in skin include substances such as amino acids, inorganic salts, Lactate and Urea. The UreaRepair PLUS range replicates the natural composition of NMFs in healthy skin, giving dry skin the substances it needs for optimal hydration.
