 - Urea

Urea

Urea

Urea is not only a metabolic waste product of the kidneys but also a natural moisturizer which can be found on the skin with a content of up to 7 %. In case of psoriasis and neurodermatitis the content of urea is considerably reduced at the concerned skin parts (sometimes it goes down until 3,5 %). Products with a content of up to 10 % urea have a strong moisturising effect, higher concentrations have keratolytic properties (soften callused skin). There are no natural sources to obtain urea which would be suitable for cosmetics, thus nature identical urea is obtained from carbon dioxide and ammoniac under high pressure and high temperature. On irritated skin or open wounds, urea could cause a short burning feeling.

Under “special ingredients -> urea” you will find more information about our certified products with urea.
