Many people don’t know why their faces are prone to redness and are hard to get rid of, which is actually related to many reasons.
The upper layer of our skin is the epidermis, which is primarily protective (the barrier), and the lower layer is the dermis, which provides nutritional functions and performs related physiological activities. Within the dermis, a large number of small blood vessels and capillaries are distributed to transport nutrients and carry away waste. The walls of the capillaries are very thin, with the thinnest vessels allowing only one red blood cell to pass through (pictured below), which can be as thin as a cicada’s wing. Many physiological and pathological factors can cause capillaries and small blood vessels to dilate. In women, the epidermis itself is thinner, so once the blood vessels are dilated, the walls become thinner, and blood flow increases, more redness is visible to the naked eye, which is the underlying cause of red blood.The main causes of vasodilation are
