What's the matter with the little red dots under the skin

There are small red spots in the subcutaneous tissue, which are generally bleeding spots. That is to say, this phenomenon is caused by the rupture of small capillaries under the skin. There are many reasons for the rupture of small capillaries. If the weather is dry and the skin is lacking in oxygen, this situation is prone to occur. In addition, if there is vascular disease or platelet problems, such symptoms are also likely to occur.

(1) Climate and environmental factors

Long-term living in a relatively harsh living environment, such as the thin air in the plateau and skin hypoxia, leads to an increase in the number of red blood cells and compensatory dilation of blood vessels. Over time, vasoconstriction dysfunction causes permanent capillary dilation. or sailors, cooks, farmers and athletes who are exposed to wind, cold and heat for a long time.

(2) Hormone-dependent capillary dilation

It is often a sequelae of inappropriate treatment, such as the abuse of topical medications on the face (such as Fuqingsong, Piyanping, and Pikangshuang).

(3) Physical stimulation

For example, the stimulation of temperature changes causes the tolerance of capillaries to exceed the normal range, causing the capillaries to dilate and rupture. Excessive sun exposure can cause chronic photodermatitis, dry skin, etc.

(4) Abuse of cosmetics

Or long-term "skin monthly care" and improper skin peeling may cause sequelae. The acidic components of skin peeling products destroy the protective effect of the skin's stratum corneum and the elasticity of capillaries, causing capillaries to dilate or rupture.

(5) Complications of certain local or systemic diseases

Suffering from a certain skin disease (such as rosacea), etc. There are also some people whose faces turn red easily due to unclear reasons. When they have this skin problem, such as when they are hot, emotionally excited, exercising vigorously, or drinking, not only will the color deepen, but the whole face will become flushed (i.e. red face, Guan Gong face), which is difficult to subside and affects the appearance. The faces of patients with telangiectasia appear redder than normal skin color. Some patients only have redness on both sides of their cheekbones, with round borders, and are jokingly called "red balls". This type of skin is thin and sensitive, and the face turns redder when it is too cold, too hot, or emotional. It mainly affects the appearance, and some people develop psychological problems because others often misunderstand that they are too shy.
