The new Hansaplast Regenerating Foot Cream features 10% urea. What exactly is urea, and how does it help to smoothen dry feet?
Dr. Ivan Bristow: Urea is a substance that exists naturally in the upper layers of our skin, produced by the body through the breakdown of skin proteins. It plays an important role in the natural moisturizing factor (NMF) complex, keeping the skin constantly moisturized. Additional urea that is applied through a foot cream increases its hydration by attracting and binding water in the upper layers of the skin, known as the epidermis. It basically acts as a binding molecule. This is not only important for maintaining supple skin, but also to strengthen its protective function. In sum, urea is a a highly effective moisturizer.
