What is the reason for bloodshot skin?

The appearance of red blood streaks on the skin is caused by skin damage. Skin thinning, damage, skin peeling, allergies, etc. will expose the capillaries under the skin to the surface of the skin, causing blood streaks to appear on the skin surface, which looks a bit scary. The appearance of red blood streaks on the skin is due to damage to the dermis below the epidermis. Some mites drill into the dermis and form red blood streaks after a period of time. So, how do red blood streaks appear? Let me give you a detailed introduction below.

Red blood streaks are mainly manifested as dilation of skin capillaries, which is caused by low skin immunity. The common cause of red blood streaks is damaged keratin, which causes capillaries to lose the natural protection of the stratum corneum and are thus exposed to long-term external environmental stimulation, leading to blood vessel dilation, congestion, and damage. It is a facial phenomenon caused by the congenital shallow position of capillaries on the face, thin and sensitive skin, and the face becomes redder when it is too cold, too hot, or emotionally excited, thus forming the red blood streak phenomenon.

Causes

Long-term use of drugs, A acid, fruit acid, and skin peels can cause skin damage, thinning, and fragility.

Caused by external force or improper extrusion. Many people have deformed capillaries in the wings of their noses and nasal grooves, which is the result of improper squeezing of acne and pimples.

Parasites such as mites enter the dermis through the hair follicles and can cause serious damage to the skin after a period of time, causing local "red face".

Regional factors: such as plateau climate stimulation and high altitude, which causes skin hypoxia, leading to an increase in the number of red blood cells and causing capillary dilation and rupture. The capillaries suffer from poor circulation due to lack of oxygen, and the blood vessels become necrotic.

Physical factors: living in high-altitude cold areas or suffering from frostbite, which leads to obstructed blood circulation and congestion of blood vessel walls, resulting in red blood streaks on the face; cold stimulation, dry air, sandy climate, and sun exposure make the capillary tolerance exceed the normal range, causing the capillaries to dilate and rupture.

Occupational factors: such as chefs, welders, etc. who are exposed to flames.

Disease factors: Complications of local or systemic diseases causing dilation and rupture of capillaries.
