Atopic dermatitis (AD) is a common skin disorder, especially in the pediatric population. Genetic and immunological factors, epidermal barrier defect, as well as skin microbiota imbalance with increased colonization by Staphylococcus aureus (SA) are involved in the pathogenesis of the disease. One of the AD topical treatments is sodium hypochlorite (NaOCl) as a 0.005% water bath solution. This substance has been used for years as an antiseptic preparation. Studies show that NaOCl has an antimicrobial effect but probably at higher concentrations than those used in AD treatment. Nevertheless, many research studies confirm the anti‐inflammatory and anti‐itching effects of NaOCl, which contributes to clinical improvement in AD patients as well as reducing the need for local steroids and antibiotics. Bleach baths seem to be a well tolerated, cheap, and easily available therapy. However, research still should be continued to evaluate its antibacterial efficacy, anti‐inflammatory effects, and safety.
