When to Worry About Cracked Skin With Atopic Dermatitis

Atopic dermatitis weakens the skin barrier and can leave dry, inflamed areas that split, especially on the hands, face, folds, and other frequently rubbed sites. Itching can lead to scratching, which widens fissures and makes them sting when water or products touch them.

A crack is more concerning when the surrounding skin becomes increasingly red, hot, swollen, or tender, or when yellow crust, pus, or a bad smell appears. Repeated fissures can also interfere with sleep, work, walking, or bending a joint and may mean the treatment plan needs adjustment.

Wash gently with lukewarm water and a fragrance-free cleanser, then pat dry. Apply a thick, bland moisturiser soon after washing and reapply whenever the skin feels dry. Cover painful fissures with a clean dressing that does not stick to the wound. Keep nails short, use gloves for wet or chemical tasks, and avoid picking flakes or scabs.

Contact a clinician if cracks are deep, bleeding repeatedly, failing to heal, or limiting movement despite careful moisturising. Seek prompt care for spreading redness, increasing warmth, swelling, pus, honey-coloured crusts, fever, or rapidly worsening pain. Urgent assessment is needed if swelling affects the lips or breathing, or if a widespread blistering rash develops.

Ask whether the fissures show infection, which moisturiser and dressing are suitable, how to manage itching, and whether your current anti-inflammatory treatment needs changing. Tell the clinician about soaps, gloves, work exposures, and products that sting.
