Cause: Wearing masks for extended periods cause heat and friction upon the skin around the mouth, nose and chin. The moisture generated when you breathe can become trapped on your skin when you wear a mask, leading to an increase in humidity that can further irritate the skin. It causes skin to become dry, raw and itchy, and it can also lead to the pores on your face becoming blocked with sweat, oil, moisture and dirt. These blocked pores can then develop into pimples or, in more severe cases, acne cysts.
Solution: Change your mask frequently and wash your face twice daily with a gentle cleanser. It is important to keep skin hydrated to avoid dryness and excess oil production and exfoliate once a week too to draw impurities out of the skin. It also helps to wear minimal or no make-up.
