Cracked heels are known medically as heel fissures and are most often the result of extremely dry skin, or xerosis. In fact, deep cracks can form along the back edges of the heel that are painful and sometimes deep enough to bleed. For most people, this condition is annoying, but in diabetics and those with poor circulation, deep heel cracks can provide a portal for infection.
Laclie Phramacy in Orillia compounds a remedy for cracked heels that contains 40% urea . Urea creams, such as Keralac, are used to heal certain skin conditions, but can also be used to treat heel fissures. Urea creams contain both an emollient and a keratolytic that work together to moisturize and remove dry, cracked skin. The emollient imparts an oily layer on top of the skin that holds in water and the keratolytic works by dissolving the horny layer of skin, softening it. Urea creams are for external use only, and should not be used near the mouth or eyes.
