What should you know about over washing hands dermatitis?

Cleaning your hands remains important, but technique, water temperature, drying, and moisturising can reduce irritation.

Repeated contact with water, soap, alcohol sanitiser, detergents, and cleaning chemicals can disturb the outer skin barrier. Once that barrier is impaired, irritants enter more easily and water escapes more readily. The hands may become red, rough, tight, scaly, sore, or split around the knuckles and fingertips. Contact allergy, atopic dermatitis, or infection can produce similar findings, so persistent symptoms should be assessed.

Use lukewarm water and a gentle, fragrance-free cleanser when washing is needed. Rinse thoroughly, pat dry rather than rubbing, and apply a thick emollient while the skin is slightly damp. Reapply after washing and before sleep. Wear suitable protective gloves for wet or chemical work, with clean dry hands underneath, and change gloves if moisture collects. Prescribed topical corticosteroids may be used for an inflamed flare when appropriate.

Arrange medical review for painful cracks, recurrent flares, spreading redness, blisters, oozing, crusting, or symptoms that interfere with work or sleep. Seek urgent help for rapidly increasing swelling, severe pain, fever, or redness spreading up the hand or arm.

Ask whether this is irritant or allergic dermatitis, which emollient texture suits your work, whether patch testing is needed, and when topical corticosteroids or another treatment should be used.
