Urea

Urea is a natural moisturizing factor (NMF) found in healthy skin. In skincare, it acts as a humectant, drawing moisture into the skin, and at higher concentrations, it has keratolytic properties, helping to exfoliate dead skin cells. It can improve skin hydration, barrier function, and texture.

Frequently asked questions

What is urea and how does it benefit the skin?

Urea is a compound naturally present in healthy skin, acting as a powerful humectant to attract and hold moisture. At higher concentrations, it also helps to gently exfoliate dead skin cells, leading to smoother and more hydrated skin.

Can urea cause irritation?

While generally well-tolerated, urea can cause mild irritation, stinging, or redness, especially at higher concentrations (above 10%) or on sensitive or broken skin. It is advisable to start with lower concentrations if you have sensitive skin.
