The role of the Demodex mites in the development of rosacea and perioral dermatitis

Current review contains the latest data on the Demodex mites and their role in the development of rosacea and perioral dermatitis, which are the most common acneiform dermatoses. Despite years of intense research and multiple publications devoted to this problem, the etiology of these dermatoses remains unknown, the mechanisms are still unclear. In recent decades, the role of Demodex folliculorum and Demodex brevis in the development of rosacea and perioral dermatitis has actively been discussed; however, the impact of the Demodex mites remains poorly understood so far.
