Diluted bleach baths reduce the severity of eczema.

Is it true that Diluted bleach baths reduce the severity of eczema?

Partly. Two randomized trials (Malaysia, and a pediatric crossover trial) and one small open-label adult trial report that diluted bleach baths improve atopic dermatitis severity, but the pediatric randomized crossover trial found no advantage over plain water baths, and the evidence covers only specific populations and short treatment periods.
