Comparison of epidermis characteristics as a result of different mask type usage in young adults

The COVID-19 pandemic highlighted the importance of foundational disease control measures, including respiratory protective equipment; however, prolonged daily use of masks can cause a shift in the skin's physiological properties. These changes are likely the cause of mask-related acne, but not much is known about why these issues occur, and even less is known about the varying effects between mask types. This study compares the effects of surgical and cotton masks on the facial skin's pH, temperature, moisture, and oil in three areas (cheek, nose, and forehead). The epithelial characteristics of individuals were analyzed before and after both short-term and long-term mask usage. Statistical analyses revealed a significant trend of increased temperature, moisture, and oil after long-term use of both mask types. Short-term use revealed a significant rise in cheek temperature after wearing surgical and cloth masks for 45 min. However, no significant changes were found with the other epithelial characteristics after short-term mask use. Understanding these mechanisms is crucial for implementing healthy protective measures. Overall, this study provides insights into the impact of mask use on facial skin and informs mask choice amidst pandemic public health measures.
