What is the first treatment for dyshidrotic eczema?

Dyshidrotic eczema, also called pompholyx, causes intensely itchy small blisters on the palms, sides of the fingers, or soles. During a flare, a clinician may prescribe a topical corticosteroid to calm inflammation. Thick fragrance-free moisturiser supports the skin barrier between and during flares. Gloves, detergents, metals, sweat, and repeated wet work can aggravate symptoms for some people, so the pattern of triggers is useful to record.

Use the prescribed cream exactly as directed and moisturise after gentle washing. Avoid bursting blisters, harsh soaps, and prolonged contact with water or cleaning chemicals; use protective gloves with a soft lining for wet tasks. If flares keep returning or do not settle, a dermatologist may discuss patch testing or narrowband UVB phototherapy.

Arrange prompt review if the hands or feet become increasingly painful, warm, swollen, crusted, or pus-filled, or if you develop fever. Seek help quickly when blisters are extensive, walking or using your hands becomes difficult, or treatment is not controlling the flare.

How strong should the topical corticosteroid be, and for how long? Could an exposure be triggering my flares? When would phototherapy or another option be considered?
