Exfoliative Keratolysis: Causes, Symptoms, and What to Do in the United Kingdom

No — it is not infectious. The condition is not caused by bacteria or viruses and cannot spread to family members or colleagues.

Heat and sweating soften the outer skin layer. As it dries, the cells detach more easily, producing the characteristic peeling. Summer activities (sports, outdoor work) also increase friction on the hands.

Eczema typically causes more itching, redness, and weeping. Fungal infections often show ring-shaped red borders, affect the feet and nails, and may have an odor. Keratolysis is usually less inflamed and primarily on the palms. A dermatologist can confirm the diagnosis.

Look for emollients that restore the skin barrier — formulas containing urea, lactic acid, or silicone are commonly effective. Consistency matters most: apply after every hand wash and before bed, regardless of the specific product.

Generally no — it is harmless. Neglected skin can develop painful cracks that raise the risk of secondary bacterial infection, but consistent moisturizing and irritant avoidance usually prevent this.

Persistent or frequent recurrence warrants a dermatologist visit. There may be an unidentified trigger at work, contact allergy, or a condition (like palmar hyperhidrosis) that responds to targeted treatment — light therapy or sweat management, for example.
