Skin trouble from wearing a mask for long hours became a worldwide complaint from 2020. In Japan, mask-wearing has remained fairly common since then, and a body of everyday know-how about "mask rash" (マスク荒れ, masuku-are) has built up. This article sums up the causes and the habits people here use.
| Cause | What happens | Direction of action |
|---|---|---|
| Friction | Redness on the cheeks, nose and behind the ears | Get the size right; a soft inner material; slip in a layer of gauze |
| Humidity | Humidity and temperature rise inside; sweat and sebum build up | Take it off now and then to wipe away sweat; change the mask |
| Drying | When you take it off, the moisture inside evaporates all at once | Moisturise after removing it |
The Japanese Dermatological Association lists contact dermatitis, worsening of acne and dryness around the mouth among mask-related skin problems, and advises choosing a material that suits your skin and keeping it clean. With non-woven masks, the ear loops and the metal nose strip can also be irritants.
[Verify] Check the content of the Japanese Dermatological Association's Q&A and the Ministry of Health, Labour and Welfare's current position on mask-wearing.
Inside a mask the skin is humid, so ingredients penetrate more easily and irritate more easily. "Thin and simple in the morning" is the practice shared among people in Japan.
Sweat, sebum and moisture from your breath build up, irritating the skin and letting bacteria multiply. Many people change masks once at midday.
Cloth can irritate too, through detergent residue, loose fibres and damp that never fully dried out. Cleanliness and fit matter more than the material.
Layering make-up over a chafed area increases friction and irritates again when you remove it. While the skin is sore, the cautious choice is to leave that area bare.
If redness, itching or bumps last 1–2 weeks or more, contact dermatitis or a similar condition is possible. See a dermatology clinic (covered by Japanese health insurance). This is not something to keep dealing with within the limits of cosmetics.
