Background During the coronavirus disease 2019 pandemic, mask wearing was obligatory in many countries to decrease infection risk among individuals. However, long-term mask wearing was associated with the development of various adverse skin reactions. Objective To assess possible dermatological complications due to mask wear during the coronavirus disease 2019 pandemic among a sample of the Egyptian population. Patients and methods The present hospital-based cross-sectional study included 320 patients who had attended outpatient dermatology clinic of the university hospitals with any dermatological symptoms. Patients wore face surgical masks during the pandemic for at least 3 months during outdoor activity.

The most common skin finding was Maskne (46.9%), followed by contact dermatitis, perioral dermatitis, and rosacea (14.1, 9.4, and 7.8%, respectively), while the remaining 21.9% were complaining of nonmask-related dermatoses. There was a significant positive correlation between mask-wearing duration and disease severity (P
