The treatment required for a skin wound is to stop the bleeding, clean the wound and bandage it, and at the same time pay attention to supplementing vitamins in order to prevent scarring. 1. If the wound is a small abrasion, the blood will flow out with the wound, and the platelets have the function of coagulation, so the blood will be transformed from liquid state to solid state during the process of blood flow, so as to achieve the effect of stopping the bleeding. 2. The next step is to debride the wound. You can use hydrogen peroxide and saline to flush out the dirt and impurities in the wound for initial disinfection, and then disinfect the wound with iodophor to further sterilize and disinfect the wound and prevent infection afterwards. 3. Finally, the wound should be bandaged with sterile gauze and changed daily to reduce the chance of infection and prevent scarring. Finally, do not pick the scabs when the wound scabs, let it fall off naturally, which is an important step to prevent scarring, and eat more fresh vegetables and fruits containing vitamin C and protein-rich foods, which is conducive to the recovery of the wound.
