What is urea?
It is not until the 19th century, when the scientific world learned about an organic compound called urea, when it was extracted in a form of white crystals, reminding by its appearance the white sault.

The small size of urea’s molecules is its important feature. Such form allows for urea to penetrate in deep layers of epidermis, while transporting biologically active substances. This very feature enforces its properties: moisturizing, soothing, exfoliating, accelerating skin regeneration, reducing inflammation, with antibacterial effect.

Epidermis with urea normal level is firm, smooth, and has a healthy color. To achieve such effect, it is added to cosmetic products in a concentration of 2% to 10%. Recommended concentration for a dry, but healthy skin is 5%.

There has been performed a research in Cincinnati university (state Ohio, USA), regarding urea safety application on the skin. It was proven, that urea does not hold any negative effect if applied on skin, inhaled or swallowed.
