The product contains urea — will it sting if my heels are already cracked, and how should I apply it in that case? — Foot Cream "Gentle Feet" Nourishing 90 ml - Dr. Sante

Urea is a well-established humectant in foot care because it helps the outer skin layer hold water more effectively. However, on skin where the barrier is compromised — visible cracks, raw areas, or inflamed fissures — urea can cause a noticeable stinging or burning sensation. The product information notes this explicitly. If your heels have shallow, dry lines without open breaks, you can apply the cream normally after washing and drying your feet, focusing on the thickened edges. For deeper cracks that are painful or weeping, it's more practical to treat those spots first with a simple occlusive ointment (such as plain petrolatum or a pharmacy barrier cream) to let the skin close. Once the surface is intact, you can introduce the urea-containing cream to help prevent recurrence. If stinging persists beyond a minute or two on seemingly intact skin, rinse off and discontinue — this may indicate individual sensitivity rather than just the urea effect. People with diagnosed skin conditions (eczema, psoriasis, contact dermatitis) on the feet should check with a pharmacist or dermatologist before using urea products.
