Wound scabs are, in a sense, protective of the wound. However, if the scab does not fall off for a long time, it can cause wound scars to form. How to make the scabs fall off quickly is as follows: First, do not get infected, disinfect once a day with iodophor or iodine. Second, use ointment that softens the scab, such as erythromycin ointment, Bactrim ointment and other ointments can be applied. After using the ointment to make the granulation tissue grow quickly, the scab will fall off relatively quickly. But do not consciously remove this scab, which has an impact on the healing of the wound, especially the easy formation of scars.
