Abstract: 【Abstract】 Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with genetic, immunological, and environmental factors. Smoking may induce and aggravate AD through various mechanisms, such as impairment of the skin barrier, epigenetic modifications, reduction of regulatory T-cell function, activation of the aryl hydrocarbon receptor, and oxidative stress. Smoking is closely related to the prevalence, severity, comorbidities, and long-term control of AD. Conversely, patients with AD may have a higher rate of smoking. This review summarizes research progress in the relationship between smoking and AD.

Key words: Dermatitis, atopic, Smoking, Skin barrier, Epigenesis, genetic, T-lymphocytes, regulatory, Aryl hydrocarbon receptor, Oxidative stress
