Abstract
BACKGROUND: The spread of COVID-19 has made mask wear essential. Expecting that long-term mask wear would change the characteristics of skin, this study investigated changes in skin wrinkles and pores caused by long-term mask wear and whether or not use of moisturizers has an effect on any changes. MATERIALS AND METHODS: The study participants were 20 women who were instructed to wear a mask for at least 6 hours a day for 4 weeks. Measurements of skin wrinkles and pores were obtained before and after the 4 weeks of mask wear. The effects of application of a moisturizer were assessed by applying moisturizer within the mask-wearing area. They completed a questionnaire about skin changes at the end of the study period. RESULTS: After wearing the mask for 4 weeks, there was a significant increase in the skin wrinkles and pores; both variables decreased significantly in skin areas where a moisturizer had been applied. The results of the questionnaire-based survey indicated the study participants considered that long-term wearing of a mask had affected their skin. CONCLUSION: Wearing a mask for extended periods increases skin wrinkles and pores and using a moisturizer when wearing the mask helps to reduce this problem.
