A prospective, randomized, controlled double-blind study of a moisturizer for xerosis of the feet in patients with diabetes.

Xerosis is frequently noted in the feet of people with diabetes. The presence of xerosis increases the risk of complications, including infection and ulceration, making it imperative to counteract its effects. A prospective, randomized, controlled double-blind study was conducted to compare the efficacy of a test moisturizer containing 10% urea and 4% lactic acid versus its emulsion base vehicle in the treatment of xerosis of the feet in patients with diabetes.
