Red blood classification

The symptom of red blood streaks is quite common in life. Most people are prone to having red blood streaks on their faces. Most of these people have thin stratum corneum and fragile skin. Especially under the sun's exposure or the stimulation of cosmetics, the red blood streaks will become particularly obvious. There are many types of red blood streaks, some are congenital and some are acquired. The following is an introduction to the classification of red blood streaks.

Red blood streaks are mainly caused by the weakness of the facial stratum corneum, which makes the position of the capillaries more easily exposed to and sensitive to changes in the external environment, thus causing the capillaries to expand and cause a facial phenomenon. The face of a patient with facial erythema appears redder than normal skin color.

People often call it plateau face, red cheeks or rotten apples. Some of them are just redness on both sides of the cheekbones, with round borders, generally arranged in silk-like shapes. This type of skin is thin and sensitive, and the face turns redder when it is too cold, too hot, or emotional. In severe cases, deposited pigmentation may form and be difficult to cure. It not only affects the beauty of appearance, but also causes psychological trauma and brings great inconvenience to normal life.

The formation of facial red blood streaks is relatively complex and can be roughly divided into two categories: congenital and acquired.

Congenital

Including congenital facial telangiectasia, facial nevus telangiectasia, etc. (This type of person's blushing usually starts from childhood). Most primary cases are congenital and inherited, that is, parents or someone in the family has suffered from the disease.

Acquired

The formation of red blood streaks is mostly caused by various damaging factors in the future. The epidermis of the skin has no capillaries. The nutrition of the cells in the epidermis mainly comes from the third layer of the epidermis, the stratum spinosum. When the cells in the stratum spinosum are damaged, their ability to supply nutrition decreases. Our skin has its own repair ability. At this time, the capillaries in the dermis expand upward autonomously to help the spinous cells provide nutrients, thus forming red blood vessels. The more severe the damage to the epidermal cells, the longer the damage time, and the more severe the capillary proliferation and migration, the more severe the red blood streaks will be. When the skin is damaged by 30℅, the red blood streaks appear as dots; when the skin is damaged by 50℅, the red blood streaks appear as lines; when the skin is damaged by 70℅, the red blood streaks appear as a network; when the skin is damaged by 90℅, the red blood streaks appear as flakes.

Causes of red blood streaks

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. Facial flushing caused by transient capillary dilation. Some natural plants such as rutin have significant vascular repair effects. They can improve the contraction and relaxation of blood vessels, reduce the permeability of blood vessel walls, and thus improve red blood streaks.

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

2. 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.

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

4. 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.

5. Physical factors: Living in high-altitude cold areas or suffering from frostbite, which results in obstructed blood circulation and blood vessel wall congestion, causing red blood streaks on the face; cold stimulation, dry air, sandy climate, and sun exposure make the capillary tolerance exceed the normal range, causing capillary dilation and rupture.
