Urea is a multifunctional skincare ingredient that acts as a humectant, drawing moisture into the skin, while also working as a keratolytic, helping to gently exfoliate dead skin cells and improve skin texture. Naturally found in the skin’s Natural Moisturizing Factor (NMF), urea supports barrier repair and increases the skin’s ability to retain water.
At lower concentrations (2–5%), urea is deeply moisturizing. At higher concentrations (10%+), it also offers gentle exfoliation, making it effective for treating dry, rough patches, keratosis pilaris, eczema-prone areas, and calluses. It is commonly used in lotions, creams, foot balms, and hand treatments.
