From small to large, no matter whether the weather is hot or cold, my face is red and I don't need cosmetics. Why? How to solve it?

My skin has been allergic since I was a child. My face will turn super red when the weather is hot. Emotional after exercise, dry weather will make you blush. What should I do?

Sensitive skin, easy to blush when you exercise or get emotional, indicating that your cuticle is thin and your skin's endurance is poor. If stimulated by external or internal environment, the skin will react violently, and some redness and itching will occur. In this case, first clean the skin, wash your face with warm water in the morning and evening, then replenish moisture to the skin, repair the stratum corneum, massage the skin more, and strengthen the metabolism of the skin, all of which are helpful for the repair of the stratum corneum.

The skin is red because the cuticle is thin and the skin has poor tolerance. Just like there are cracks and holes in the wall of the house where you live, external stimuli directly stimulate the skin through these cracks. When nerve endings and capillaries are stimulated for a long time and expand, they will naturally turn red, repair the stratum corneum and enhance the skin's resistance, so that they can be slowly improved. Generally speaking, heat will dilate skin blood vessels and cause facial flushing. Although cold makes blood vessels contract, when the temperature rises, blood vessels will rebound and expand, causing blushing. But some people, at extremely cold temperatures, will also blush because of abnormal blood vessel expansion. The clinical manifestations are filiform, punctate, star-shaped or flaky erythema on the face.

When the temperature difference is too large, for example, from the cold wind blowing to the air-conditioned room, it is hot and cold, and the capillaries lose their elasticity in repeated contraction and expansion, which is reflected on the cheeks and nose, which will make the cheeks red and sting. At the beginning, the face can be restored to its original state immediately when it turns red, but if it continues repeatedly for a long time, the blood vessels contract, lose their expansion function, and harden in the state of overstretching, making the face look very red at ordinary times. In severe cases, facial flushing's symptoms will also appear after lowering the head and raising the head. This symptom is relatively calm in spring, summer and autumn, and becomes more serious in winter.

In medicine, this situation is called "flushing". Every winter, there are many patients.

Blushing is both physiological and pathological. Some healthy people have good peripheral blood circulation, a little activity and rosy complexion; Some people blush when they are shy, angry or ashamed. Some people will blush because of drinking; People living in high mountains need more red blood cells to absorb enough oxygen because the air is thinner, and once the hemoglobin carried by red blood cells increases, the color of their faces will be redder; Some people blush because of menopause, while others blush because of systemic diseases. Such as hypertension, tuberculosis and lupus erythematosus. Don't worry about physical blushing. As for pathological blushing, please consult a doctor.

From a medical point of view, blushing means that it is easier to turn red, darker and lasts longer than others due to changes in temperature or mood. There are blood vessels in the skin, which will expand or contract under the influence of nerve factors, especially the capillaries in the cheeks are rich, so the cheeks are more prone to redness. If blushing only occurs in winter, it has more to do with the change of temperature.

Generally speaking, heat will dilate skin blood vessels and cause facial flushing. Although cold makes blood vessels contract, when the temperature rises, blood vessels will rebound and expand, causing blushing. But some people, at extremely cold temperatures, will also blush because of abnormal blood vessel expansion. The clinical manifestations are filiform, punctate, star-shaped or flaky facial features.

When the temperature difference is too large, for example, from the cold wind blowing to the air-conditioned room, it is hot and cold, and the capillaries lose their elasticity in repeated contraction and expansion, which is reflected on the cheeks and nose, which will make the cheeks red and sting. At the beginning, the face can be restored to its original state immediately when it turns red, but if it continues repeatedly for a long time, the blood vessels contract, lose their expansion function, and harden in the state of overstretching, making the face look very red at ordinary times. In severe cases, facial flushing's symptoms will also appear after lowering the head and raising the head. This symptom is relatively calm in spring, summer and autumn, and more serious in winter.

The doctor suggested that in winter, we should avoid the cold environment and the sharp change of temperature, and pay attention to the moisturizing and warm work of the skin. In a particularly dry and hot room, if your face feels dry, you should replenish water in time and wash it with warm water. Scarves or masks can be used outside to prevent cold air from directly attacking the face, avoid excessive humidity difference and temperature difference, and make the dilated capillaries contract rapidly when they are cold, forming red blood. People with a history of facial frostbite should always wipe their faces in winter to promote blood circulation.

In terms of diet, doctors say that people who blush easily should eat less foods that will increase blood vessel dilation, such as coffee, tea, cola and other caffeinated foods. Supplementing some vitamin B can also help nerve repair and soothe the nerves. In addition, avoid sun exposure, alcohol, spicy food, and be less angry, nervous or overly excited, because these will all contribute to the redness of the face.
