Wash your face with cold water or hot water in winter? Wash your face several times a day, won't it shine?

Wash your face with cold water or hot water in winter? Wash your face several times a day, won't it shine? Because of the cold weather in winter, some people think that it is better to wash your face with hot water, which can reduce the irritation to the skin. Others think that washing your face with cold water can play a role in beauty and health care. In general, washing your face twice a day is enough. However, for different seasons, different skin, and the number of times you wash your face, you are also particular. For oily skin, repeated cleansing can't solve the greasy phenomenon. Because normal skin itself maintains the balance of water and oil, too clean skin will make the skin surface dehydrated and the body will maintain the balance of water. It will accelerate the secretion of oil, and eventually form a unique phenomenon of "external oil drying inside" for oily skin.

In fact, washing your face with boiling water is not as good as everyone thinks, but it will cause some bad harm to your face:

First, the skin wrinkles easily. In winter, under the stimulation of strong cold air, sweat glands and capillaries on human face gather, which will expand rapidly when encountering boiling water, but after the heat is released, it will repair the situation at ultra-low temperature. When the capillary contracts like that, it's easy to wrinkle your face.

Second, let the skin get drier and drier. Many people are resistant to facial oil, but facial vegetable oil has a very important physiological function, which can maintain all the normal defense system functions of everyone's skin. If young people have strong oil secretion, it is also effective to remove vegetable oil with facial cleanser or warm water once a day. But there is no need to remove oil too frequently, which will cause other skin problems on the face. The root cause is that too much cleaning destroys the skin barrier. Especially in winter, the temperature is low, the skin oil is reduced, and sometimes the face will feel dry. At this time, the water for washing your face should not be too hot, otherwise it will affect the skin barrier. People with dry facial skin will be dry in winter, so it is necessary to control the temperature of washing your face and keep it as low as possible.

Similarly, it is not advisable to wash your face in cold water. Low temperature water will cause facial blood vessels to contract, and the metabolism of sebaceous glands will be significantly reduced. The direct side effect of this is that the skin becomes drier. Secondly, if you want to wash your face with cold water when sweating, you will be suddenly stimulated by cold water because of the high skin temperature, which will lead to the tightening of skin pores, and the oil stains and sweat in the skin pores cannot be cleaned up, which will lead to inflammation. Finally, washing your face with cold water may also cause off-line wind, and facial paralysis is mostly caused by cold and virus infection when your body's immunity drops. As a cold irritant, washing your face with cold water will stimulate the nervous system and produce off-line wind if it is not properly operated.

Therefore, it is best to wash your face with warm water below 30℃, which is not only easy to wash off the dust on your face, but also helps to clean the pores of your skin. The skin barrier is a natural barrier composed of thin cells in the stratum corneum, intercellular "lipids" and "natural moisturizing and hydrating factors". Somatic cells are the basic structural characteristics and functional enterprises of organisms. In the Secret Exhibition Area of Life of Chinese Academy of Sciences, you can see enlarged three-dimensional animal cells at a glance, and vividly grasp the appearance, various components and actual functions and effects of somatic cells.

Because of the sensitivity of skin, sensitive skin is particularly sensitive to external stimuli, so don't wash your face too often. Otherwise, washing away the protective layer on your face will make your skin more allergic. So if the weather is suitable in spring and autumn, wash your face twice in the morning and evening. As we all know, if it is summer, the skin is very prone to oil, and people with oil-soluble skin can reasonably increase the frequency of washing their faces; If in winter, too sensitive skin should moderately reduce the frequency of washing your face.

At night, you can use cleaning liquid to clean things once. Wash gently with boiling water in the morning. Cleaning the face and skin is inseparable from water. You don't have to underestimate the face wash. Even with the best facial cleanser, if the facial cleanser is not right, it will not achieve the expected actual effect. The correct way to wash your face is to use warm water first and then cold water, that is, wash your face with warm water (about 34℃) first and then pat it with cold water, which can not only clean your skin.

It can also dilate and seal the capillaries on the surface of the skin, improve the actual inhalation effect of the skin, promote the facial blood circulation system, and achieve the actual effect of beauty and fitness. The best washing water should be flowing water, that is, try not to wash your face with a washbasin. No matter whether the washbasin is clean or not, it is said that the water in the washbasin has suffered environmental pollution in the process of washing your face, and only it is "secondary pollution". So it is best to choose liquid water.
