Patients in convalescence must be careful not to dig the scab area with their hands, keep the wound clean and dry, avoid contact with water to prevent infection, and it is best not to eat food that is easy to cause pigmentation. If you dig a scab, you may not leave a scar. Mainly depends on the size of the wound and your own physique. First of all, if the wound is only on the dermis, there will be almost no scar after recovery, but if the injury has reached the dermis or subcutaneous tissue, it can only be replaced by fibrous tissue when recovering. When these cells heal wounds, they will produce scars. Then there is the scar constitution. No matter the size of the wound, these patients will have abnormal cell proliferation, and eventually there will be obvious scars.
After the scar appears, you can eat more fruits and vegetables, less spicy and greasy food, no seafood, no smoking and no drinking. Severe scars can also be treated with lasers and intense pulsed lasers. The thickness of scab reflects the degree of tissue fluid oozing from the wound. When it contains more cellulose and red blood cells, the scab may be thicker, which can protect the wound from bacteria and harmful substances in the air. After the wound heals, the scab will slowly fall off on its own. Scar is a protective reaction after injury. The main components of scar formation are thrombus in tissue and early formation of granulation tissue.
Repeated scabbing of small wounds will leave scars, depending on the depth of the wound. If the wound is shallow and only has cortex or burns, don't peel it off in a hurry, it will fall off naturally and basically won't form scars. Even if a shallow scar is formed, it will gradually disappear with time. Surgical resection or instrument trauma to a deeper degree will definitely form scars after healing. After the injury, go to the hospital for suture in time to reduce its tension and reduce the later scar. After the wound is healed, you can choose to use external ointment to remove the scar.
