An epidemiological study on face masks and acne in a Nigerian population.

Abstract

BackgroundAcne vulgaris is a skin disorder that affects males and females with significant impact on quality of life. The onset of the COVID-19 pandemic led to a series of non-pharmaceutical interventions globally to reduce the spread of the virus particularly since there have been no known cures or definitive treatment for the disease. One key non-pharmaceutical intervention was recommendation on wearing of face masks. There are reports of discomfort associated with wearing face mask including complaints of various skin rashes, acne and headaches which could hinder appropriate use of face masks. While the dermatological problems associated with face mask use have been comprehensively explored in high income countries, the data is sparse in sub-Saharan Africa. We aimed to determine the association between face mask use and development of acne vulgaris in our developing country setting. We subsequently determined risk factors for development of acne vulgaris such as duration of wearing face masks, type of face mask, and prior dermatological skin condition history. We aimed to also determine the potential of acne development secondary to face mask use to reducing predisposition to wearing face masks.MethodsThis was an observational cross-sectional study conducted in within two local government areas of the Federal Capital Territory, Abuja. Trained interviewers administered pre-tested questionnaires to 1316 consecutive consenting adult participants randomly approached for informed consent at various public locations. Information was inputted into MS Excel and analyzed using Epi-info.ResultsA total number of 1316 persons participated in this study with mean age 34.4 ±12.3 years and median age 35.5years. Male: female ratio was 1:1.41. New onset acne or worsening of acne following consistent wearing of face masks was reported by 323 (24.5%) of the 1316 participants in this study. The surgical face mask was the least likely to predispose to acne pConclusionOur finding of greater predisposition to development or worsening of acne following consistent use of face masks could have implications for the control strategy of COVID-19. The finding that the N95 face mask was more significantly associated with acne is of concern as this is the preferred face mask in healthcare settings. It is important for the medical community to investigate feasible and safe recommendations to help alleviate this condition.
