The stages of scar formation, how the scar is formed

It's just that the cells don't grow flat when they grow new.

Scars left on ** or in internal organs due to the replacement of injured tissue by new connective tissue.

Formation of new capillaries 24 hours after tissue injury; 3 days after injury, granulation tissue is formed, and collagen fibers appear;

Scar tissue formation 1 week after injury; Later, the scar increases, the tissue edema decreases, and the wound** turns from red to normal skin color, and then enters the proliferative and mature phases.

Proliferative phase: usually occurs within 6 months of injury. After the wound heals, the scar changes from light red to bright red to purplish red, and the surface is induration, itching, and the scar thickens up to several millimeters.

It reaches its peak in 3-6 months, when the texture is hard, the itching and pain are obvious, especially at night, and joint deformity and dysfunction can occur.

Maturity stage: usually within 6-24 months after the injury, when the color of the scar changes from purplish-red to light brown, and finally closes to the color of the neighboring **, and the itching pain is reduced or disappears.

Scars, medically called scars, usually after scarring, there will be no keloid hyperplasia or only slight keloid hyperplasia and then begin to fade gradually, mature, stationary, a few scars can go through months and years, or even longer, and finally flat, soft, close to normal**, these are called normal scars. At the beginning of the formation of normal scars, the symptoms can be lightened through diet, nursing, etc., plus the repair function of ** itself.

Some scars will proliferate with the changes in the body, and even grow larger and larger, significantly higher than the ** surface, and the color is reddish-brown, the texture is very hard, often itchy, stinging or tight; Scarring, which may even erode normal**, expand and proliferate, form contractures in the joints, or cause infection due to repeated ulceration, usually require prompt scarring**.

When we are damaged, we repair ourselves. But the scar is the inevitable product of our repair process.

Scar is a very general concept, it is a general term for the appearance and histopathological changes of normal ** tissues caused by various traumas. It is a normal and inevitable physiological reaction in the natural healing process of wounds or wounds after human trauma, and it is also the inevitable result of the wound healing process. The essence of scar is a kind of abnormal and unsound tissue that does not have normal tissue structure and physiological function, and loses the vitality of normal tissue.

Scars not only destroy the beauty of the body, but also hinder the physiological function of the relevant tissues or organs, and even lead to deformities.

Scar is a normal and inevitable physiological reaction in the natural healing process of wounds or wounds after trauma, and it is also the inevitable result of the wound healing process. There are two types of trauma repair. One is a superficial wound that only affects the epidermis, starting from the epithelial cells of hair follicles and sebaceous glands, and healing through simple epithelial formation.

After repair, the complete restoration of structural integrity and function can be achieved. The other is damage that reaches deep into the dermis and subcutaneous tissues, which is repaired by scarring.

瘢, the Chinese character, the basic meaning of the word is scar, scar, spot: knife scar. Sores. Sweat scars. Sparrows.

There is no clear distinction, scar is the more commonly spoken language, and scar is written language.

Scars and scars are not the same to be precise, the difference is that scars are generally caused by trauma, mainly caused by slight friction or incisions and burns, and are relatively shallow scar symptoms, the symptoms are often not particularly severe, and sometimes they can slowly heal themselves over time, ** are often simpler than scars. Scar is a general term for the appearance and histopathological changes of normal tissues caused by various traumas, such as trauma, burns, acne, etc., which is an inevitable product of the human trauma repair process.
