Urea is a commonly used moisturizing ingredient in foot-care products because it helps attract and bind water in the upper layers of the skin. In this cream, the concentration is 4%, which makes it suitable for softening dry, rough foot skin and supporting moisture retention in areas that often become thick or coarse, such as heels and soles.
Urea also helps loosen the links between hardened surface cells. In practical terms, this means rough patches may gradually feel smoother when the cream is used consistently. However, this product should not be understood as a strong peeling or intensive callus-removal treatment; the source information describes this moderate concentration as being aimed more at hydration and softening.
The effect is supported by other moisturizing and protective ingredients in the formula. Glycerin adds another water-binding action, while dimethicone forms a light film that helps limit moisture loss. Mineral oil and fatty alcohols contribute to the richer texture, which is appropriate for foot skin. Use on intact skin only, and introduce carefully if your feet are sensitive or irritated.
