What to know about asteatotic eczema in older adults

Asteatotic eczema, also called eczema craquele or winter itch, develops when the skin barrier becomes very dry and irritated. The lower legs are common sites, although the arms, trunk, and other areas can be affected. The skin may look flaky or fissured, with fine cracks forming a pattern like dried riverbed lines.

Age-related dryness, low humidity, hot bathing, harsh cleansers, and frequent washing can all remove protective oils. Scratching adds inflammation and can create breaks that let germs enter. A clinician can distinguish this pattern from infection, contact reactions, medication effects, or other rashes.

Use a fragrance-free, rich moisturiser several times a day and apply it soon after bathing while the skin is still slightly damp. Choose lukewarm rather than hot water, keep bathing brief, and use a gentle cleanser only where needed. Pat dry instead of rubbing.

Wear soft fabrics, keep nails short, and use a cool compress when itching rises. A clinician may recommend a short course of an anti-inflammatory cream or another treatment if moisturising alone is not enough. Follow the directions for the product and avoid applying a medicated cream to new areas without advice.

Arrange a review when cracks persist, the rash repeatedly returns, or itching disrupts sleep. Seek prompt care for spreading redness, warmth, swelling, pus, fever, or increasing pain, which can signal infection. A rash that does not improve with careful moisturising also deserves an examination.

Ask which moisturiser texture suits your skin, whether a cleanser or medicine may be worsening dryness, how to use prescribed treatment on cracked skin, and what signs mean the rash needs an earlier review. Mention any new medicines or health changes.
