Answer

A randomized, investigator-blinded, placebo-controlled trial including 31 patients showed that intranasal mupirocin ointment and diluted bleach (sodium hypochlorite) baths improved AD symptoms in patients with clinical signs of secondary bacterial infection. [7] Multiple studies have now confirmed that bleach baths are highly effective in treating AD by limiting disease severity. [65] The most likely mechanism is reduction of superinfection with bacteria such as S aureus, thereby mitigating proinflammatory stimuli.
