After appendicitis surgery, the wound is relatively small, and the human body has the ability to remove the scar, which can be repaired within 4 months. During the scar repair period, it can be applied with a hot cotton towel, or moderately massaged to promote the scar. The surrounding circulating blood can dilute the scar, or rub aloe gel and scar removal cream, which can have the effect of eliminating the scar. At the same time, eating more fresh fruits containing vitamin C and vitamin E will help remove scars, such as carrots, tomatoes, papayas, kiwi fruits, blueberries, etc. When the scar exceeds one year or so, the laser can be selected to remove the scar.
