Depending on the climate, patients usually benefit from 5-minute, lukewarm baths followed by the application of a moisturizer such as white petrolatum. Frequent baths with the addition of emulsifying oils (1 capful added to lukewarm bath water) for 5-10 minutes hydrate the skin. The oil keeps the water on the skin and prevents evaporation to the outside environment. In infants, 3 times a day is not a great burden; in adults, once or twice a day is usually all that can be achieved. Leave the body wet after bathing.
Advise patients to apply an emollient such as petrolatum or Aquaphor all over the body while wet, to seal in moisture and allow water to be absorbed through the stratum corneum. The ointment spreads well on wet skin. The active ingredient should be applied before the emollient. Newer emollients such as Atopiclair and Mimyx have been advocated as having superior results, but they are expensive and need further evaluation
A midstrength steroid ointment (triamcinolone or betamethasone
valerate) is applied 2 times daily to lesions on the trunk until the eczematous lesions clear.
