Answer

Lukewarm or cool baths or showers reduce itching and help rehydrate the skin; a gentle soap or liquid cleanser may be used. Skin should be patted dry and then moisturizers are applied to still-damp skin. The "soak-and-smear" therapeutic regimen includes a 20-minute plain water soak each night followed by application of steroid ointment or petrolatum to wet skin and includes alteration of cleansing habits so that soap is applied only to the axilla and groin. One study showed greater than 90% response in 27 of 28 patients with refractory chronic pruritic eruptions when the regimen was followed as directed. [31]
