My face gets hot and red in the afternoon

In daily life, there must be people who blush easily. Some of them are because they are nervous, which causes blood flow to accelerate, making their face red and hot. This is very normal. But some people would blush just by sitting in their seats, and would blush while talking to others. This kind of blushing is not because of shyness. It is most likely due to skin sensitivity or certain skin diseases. You still need to go to the hospital for examination as soon as possible.

The following is an introduction to the pathological nature of facial redness and the causes of redness:

There are many reasons for facial flushing, one of which is facial redness. Facial red blood streaks refer to a skin disease caused by dilation of facial capillaries. Dilated facial capillaries can give the face a "red face" appearance. It can be roughly divided into two types: hereditary and induced. The hereditary type is mostly inherited and often familial; the induced type is the most common.

Causes of flushing:

One is that long-term local use of corticosteroids causes capillary dilation, leading to skin thinning and atrophy.

The second is living in high-altitude cold areas or suffering from frostbite, which causes obstructed blood circulation and congestion of blood vessel walls, resulting in red blood streaks on the face.

The third is cosmetic skin resurfacing. Because skin resurfacing products mainly contain benzoic acid, benzoic acid repeatedly stimulates the thin, delicate facial areas, exposing the unprotected dermis to the outside and exposing it to strong ultraviolet rays.

Fourth, sensitive skin generally has a thin stratum corneum, and is more sensitive to external sunlight, medicines, cosmetics, temperature (hot or cold), etc., which causes the blood vessels to tighten and loosen, presenting repeated congestion, causing the blood vessels to dilate tortuously, and forming red blood streaks.

People with facial flushing are easily affected by climate and emotions. The flushing phenomenon will be more obvious after exercise and when they are emotionally excited. Frequent entry and exit of spaces with large temperature differences in winter will cause the capillaries in the face to dilate, aggravating the severity of facial flushing. Many people living in plateaus and cold areas experience facial flushing, which is the most powerful evidence of the impact of temperature environment on the face.
