After the tattoo is repaired, you will encounter skin hyperplasia scars. This problem has been troubled for many years and cannot be solved. Here, I will analyze as many tattoos and scars as possible from various fields to make it easier for colleagues and tattoo customers to deal with them later.
1 What are scars
Scars are formed after the skin tissues of the human body are subjected to various external traumas, and the fibrous connective tissues of the wounds heal where the wounds heal, fill, connect, support, and protect the surrounding normal tissues. In other words, the formation of scars is a normal biological repair process of the human body. If there is no scar repair after the wound, the wound cannot heal. Sometimes the trauma only damages the epidermis of the skin or the superficial layer of the dermis, such as sunburn, superficial abrasions, burns, etc., without affecting the germinal layer of the skin, there will be no scars, of course, this is only very small Trauma. When a true trauma occurs and the entire layer of skin is damaged, fibrous connective tissue proliferates massively, forming hard scars, often accompanied by symptoms such as itching and pain. Sometimes the scar tissue continues to spread to the surrounding normal skin, forming hypertrophic scars or keloids.
2 Physical formation factors of scars
It is generally believed that the formation of scars is caused by the body's inflammatory reaction, the imbalance of collagen fiber synthesis and degradation, the appearance of abnormal mucopolysaccharides, and the proliferation of myofibroblasts. Hyperplastic scars have reduced lymphatic reflux and local edema, which can lead to hypertrophy of the scar. In short, scar formation is an inevitable product of the body's wound repair. When the body tissues, especially the skin tissues, are damaged to a certain depth, the wound surface first exhibits an inflammatory reaction, and white blood cells, macrophages, mast cells, etc. infiltrate, releasing a variety of cytokines ( Growth factor), fibroblasts and myofibroblasts proliferate and synthesize a large amount of collagen and matrix, causing abnormal collagen metabolism and arrangement, abnormal matrix deposition, coupled with the effects of microcirculation and free radical factors, promote the scar form.
3 Hyperplastic scars:
After the skin injury heals, the scars continue to proliferate and develop into hypertrophic scars. Hypertrophic scars protrude from the surface, irregular in shape, uneven in shape, flushed and congested, firm and firm in texture, with a burning sensation and itching sensation, which will be exacerbated when the environment changes, the temperature increases, the emotion is agitated, or when eating spicy and irritating food.
4 Formation of hypertrophic scars
Because collagen anabolism continues abnormally and exceeds the speed of catabolism, collagen fibers are formed for a long time.
