Researchers in Korea noted that wearing masks had become essential for many people in view of the COVID-19 pandemic,
However, the number of people complaining of skin problems caused by wearing masks is increasing.
Therefore, they investigated the characteristics of changes in sensitive skin caused by wearing a mask, and if moisturiser could help improve problems.
Writing in the journal, Skin Research and Technology, they explained: “Twenty healthy Korean women with sensitive skin participated in this study.
“To determine any skin-related changes caused by mask-wearing, we evaluated redness, hydration, transepidermal water loss (TEWL), and moisture at 2.5 mm below the surface before and 4hours after wearing a Korea Filter 94 mask.
“In addition, we tested whether applying a moisturiser for 30 min after mask removal could reverse any mask-induced changes.”
They found that skin redness and TEWL were significantly increased at four hours after wearing a mask, while skin hydration and the 2.5 mm moisture were significantly decreased.
After applying the moisturiser, skin redness and TEWL were significantly decreased compared to their values four hours after wearing masks, whereas skin hydration and the 2.5 mm moisture were significantly increased.
They added: “Moreover, after applying the moisturiser, skin redness and TEWL were significantly reduced compared to the pre-masking baseline, whereas skin hydration was significantly increased; the 2.5 mm moisture showed no significant change.”
