Risk factors for the development of acne in healthcare workers during the COVID-19 pandemic.

The COVID-19 pandemic has led to many healthcare workers having prolonged contact with tight-fitting masks, leading to maskne. "Maskne" is defined as acne secondary to mask use. There are limited studies on maskne during the COVID-19 pandemic. The objective of this study is to identify risk factors for the development of maskne amongst healthcare workers. A cross-sectional survey was completed by 227 medical students, resident physicians, and nursing students at Johns Hopkins Medicine, with 68.7% of participants reporting development of maskne. Surgical masks and respirators were the most prevalent mask types worn at work. The most common prevention methods were the use of mild cleansers and moisturizers. Chi-squared analysis was used for data analysis. The results of this study indicate that gender (p = 0.003) and duration of mask use (p = 0.048) are significant risk factors for maskne development. These factors are non-modifiable, but may be used for more targeted education for prevention.
