Operation: The active ingredient in the base rich in skin moisturizers in Maxiderma heel and foot care balms is Urea (25%), a natural moisturizer that is normally found in the skin and makes up approximately 7% of natural skin moisturizers. Urea increases the absorption of water in the dermis and thus increases the degree of hydration of the skin. Maxiderma heel and foot care balm can also be used in the treatment of dry, hard and cracked feet characteristic of diabetes. Packing: 56g
