What should you know about skin crack care?

A crack or fissure forms when the skin barrier becomes dry, inflamed, thickened or repeatedly stretched. Hands, feet, lips and areas over joints are common sites, especially after frequent washing, cold dry air or contact with detergents. Atopic dermatitis can cause itchy inflamed skin that breaks, while psoriasis can produce thick scale and fissures. A crack is a symptom, so its pattern, itch, scale and location help a clinician identify the cause.

Rinse with lukewarm water and a mild fragrance-free cleanser, then pat dry. Apply a thick emollient soon afterward and repeat whenever the skin feels tight. Cover a painful fissure with a clean dressing if friction is making it reopen. Wear protective gloves for wet work and avoid picking scale or using harsh antiseptics unless prescribed. If cracks keep returning, a clinician may recommend targeted treatment for inflammation, infection or an underlying skin condition rather than moisturiser alone.

Seek prompt medical advice if the area becomes increasingly red, hot, swollen, draining or painful, or if you develop fever. Arrange an appointment when cracks bleed repeatedly, interfere with walking or hand use, spread to new areas, or do not improve with careful barrier care. Sudden extensive cracking or symptoms around the eyes, mouth or genitals also deserve assessment.

Could atopic dermatitis, psoriasis, allergy or infection be contributing? Which emollient texture suits this body area? Should I use a prescription anti-inflammatory or protective dressing? How can I prevent the same fissure from reopening?
