It is not recommended to dry the wound with a hair dryer to form a scab, as this method cannot achieve the effect of scabbing, and if the temperature of the hair dryer is too high, it may even cause further thermal damage. For general home care of wounds, it is recommended to keep the area dry and clean, and use iodophor disinfectant and clean cotton swabs to clean and change the dressing on a regular basis. Usually, wounds will scab over on their own after a few days and do not require special treatment. If localized oozing is found, saline or boric acid solution can be used to apply cold compresses, which is conducive to rapid scabbing. If there is obvious pus in the local infection, after changing the dressing and sterilizing the wound, mupirocin ointment or fusidic acid ointment can be added for antibacterial treatment. If the situation is still not improved or even worsened, it is recommended to go to the hospital for further treatment.
