The faster the wound heals, the less likely it is to leave scars.
Experts pointed out that the general principle is that the faster the wound heals, the shallower the scar. The ideal scar is thin, flat and white, parallel to the skin lines, and not easy to detect. Many thin, flat and white scars formed by long-term degradation are also ideal scars. Most of the "stubborn" scars are wide, concave or convex, or form long scars, hypertrophy and redness. The most "intractable" scar is "swollen crab feet" (scar hyperplasia).
Generally speaking, the healing of normal wounds can be divided into three stages: inflammation and contraction reaction, granulation tissue repair and tissue reconstruction to form scars. Among them, the first stage, inflammation and contraction reaction, is very important. In the process of wound healing, inflammation and contraction are very important to avoid infection and scar formation. In addition, the contraction of the wound edge will also prompt the wound skin to secrete collagen to repair the wound tissue, which will affect the wound healing.
Age and postoperative maintenance determine the speed of wound healing.
Some people heal quickly, while others heal slowly. What does it have to do with? Experts pointed out that there are many factors that affect the speed of wound healing, including age and wound infection. , but also related to anemia, nutritional status, stress, postoperative maintenance, diet aftercare and so on.
The wound healing speed of the elderly will be significantly slower than that of the young. People who are malnourished or obese and those who lack vitamin A or C or zinc, iron and copper will gradually recover. After plastic surgery and trauma, if the blood circulation of the wound is poor and the wound is subjected to gravity, the wound will heal slowly.
Postoperative maintenance should not be underestimated. If you smoke, drink and eat spicy food after operation, the wound healing speed will slow down. People who often take hormone drugs and suffer from diabetes, chronic obstructive pulmonary disease, uremia, cancer, liver failure and vascular diseases also need longer time for wound healing than ordinary people. It must be mentioned that psychological factors also have an impact on wound healing, and people with great pressure heal slowly.
