[Explanation] An epidemic situation has made masks a "standard" for everyone when they go out. Wearing a mask for a long time can effectively prevent respiratory infections, but it may also cause damage to people's skin. Li Weiwei, director of the medical cosmetology department of a hospital in Beijing, said that "mask face" refers to skin problems such as acne caused by wearing a mask for a long time, mainly in the area covered by the mask. During the severe period of the epidemic, the hospital's medical cosmetology department visit rate increased by 20%-30%, and the increase was almost all patients with "mask face".

  It is even possible that all the patients who came today were caused by seeing this stubborn acne on the face, and it was only after an explanation that it was caused by wearing a mask.

  There is redness, swelling and acne, and then itching. Because I myself have oily skin, I love to get oily, and then I feel stuffy after wearing a mask, and then in a humid environment, the problem on my face becomes more serious.

  [Explanation] At present, epidemic prevention and control have become normal, and masks may be accompanied by the public for a long time. The weather is now in the mid-week, and the hot climate may also aggravate the symptoms of "mask face".

  As soon as you sweat, you have to wear a mask to get stuffed inside, and the whole skin condition will be more uncomfortable.

  The skin sweats, and then the overall water-oil balance of the skin, it should be said that the water-oil barrier should have some influence, so at this time it is easy to appear allergies and acne.

  [Explanation] However, Li Weiwei told reporters that the number of patients who came to see the doctor due to "mask face" has decreased compared with the previous period. This is because many people can't bear wearing masks under high temperature and chose to take them off. She urged the public not to avoid wearing masks because they are worried about "mask face".

  You can't not wear a mask because you are afraid of skin damage. This is definitely not acceptable. The epidemic situation abroad is also more serious, so we say that this vigilant heart in our hearts must exist.

  [Explanation] So, how to prevent "mask face" while insisting on wearing a mask?

  [Concurrent] Li Weiwei, Director of the Department of Medical Beauty, Beijing Tsinghua Chang Gung Memorial Hospital

  The first point is that I still (think) the quality of the mask. (If) I feel there is a smell of dust today, or there are some hairs after wearing it, and then sweating after wearing it. Whether it is dust or its dander, it will induce our subsequent skin acne.

  The second point is the length of time the mask is worn. It might be better to change a mask in four hours.

  In addition, for example, if you go to an outdoor environment, you may be 1 meter to 1.5 meters away from others, so you can properly remove the mask to give your skin some time to let it breathe. But in a closed environment, you must wear a mask to protect yourself.

  [Commentary] Li Weiwei also reminded that if you have already experienced symptoms of "mask face", you should go to a regular hospital for help and treatment, and at the same time pay attention to a healthy lifestyle, eat lightly, and reduce staying up late and anxiety.
