Urea
WHAT IT DOES:
Urea is a component of urine, although synthetic versions are used in cosmetics. It is an essential part of the natural moisture factor (NMF) of human skin and a common ingredient in hydrating products. In high volumes, urea acts as a keratolytic to soften skin.
HOW IT WORKS:
In small amounts, urea has beneficial water-binding and mild exfoliating properties for skin. In larger concentrations it can cause sensitivity.
MG SAYS:
Urea has been used in modern medicine for some time in treating the itching and burning effects of psoriasis, dermatitis, and ichthyosis. A known keratolytic urea encourages the desquamation of dead skin cells by increasing moisture in the outermost layer of the skin.
