What reason is red knot yellow scab repeatedly on the face

summary

There are many reasons for facial flushing, one of which is facial redness. Facial red blood is a kind of skin disease caused by telangiectasia. After the expansion of facial capillaries, the face can present a "red face" appearance.

What reason is red knot yellow scab repeatedly on the face

First: local long-term use of corticosteroid drugs, causing telangiectasia, resulting in skin thinning, atrophy, etc.; living in cold areas or suffering from frostbite, resulting in blood circulation blocked, vascular wall stasis, so that the face presents a red blood.

Second: after cosmetic skin change, because the skin change products mainly contain benzoic acid, benzoic acid repeatedly stimulates the thin, tender and delicate facial parts, so that the unprotected dermis is exposed to the outside and exposed to intense ultraviolet radiation;

Third: the stratum corneum of sensitive skin is generally thin. They are sensitive to sunlight, drugs, cosmetics, temperature (hot and cold) and so on. As a result, the blood vessels are tight and loose, showing a state of repeated congestion, resulting in the circuitous expansion of blood vessels and the formation of red blood.

matters needing attention

People with facial flush are easily affected by climate and emotion. After exercise and emotional excitement, the flush phenomenon will be more obvious. Frequent access to the space with large temperature difference in winter will cause facial capillary dilation and aggravate the severity of facial flush. Many people living in Plateau and cold areas will have facial flushing phenomenon, which is the most powerful evidence of the impact of temperature environment on the face.
