What is Urea?

Urea may sound familiar, and yes you are right, it does occur in your urine. But it does also naturally appear in your skin and is considered one of the most potent natural moisturising factors (also called NMF) These factors are vital for keeping the skin’s protective barrier functioning correctly and helping the skin remain in its healthiest state. Although urea makes up only 7% of NMF, unlike amino acids which add up to 40%, it is unique ability to act like a mild keratolytic agent which is able to break down the bonds in protein allowing more amino acids to work their way onto the surface of the outer surface, helping to improve the skin’s barrier and overall complexion. Urea is so moisturising it is able to help treat the skin with added hydration to restore balance and improve any excessive dryness and various skin conditions, such as psoriasis, eczema and certain types of dermatitis.
