urea
Mammalian metabolic byproduct
Urea is a nitrogen-rich compound produced when the body breaks down proteins, excreted primarily in urine.
It's also manufactured synthetically for use in fertilizers, animal feed, and various industrial applications.
In skincare, urea appears as a moisturizing ingredient: This cream contains 10% urea for dry skin.
