The use of iodophor can promote wound healing to some extent, however, the main purpose of iodophor is to disinfect and sterilize the wound. However, iodophor can promote the growth of granulation tissue to a certain extent, so it can promote wound healing to a certain extent. Wound healing is mainly related to the growth of soft tissue in the patient’s skin and the secretion of regenerative factors. At the initial stage of the wound, medical iodophor can be used to disinfect and sterilize the area, killing the bacteria, budding spores, fungi and some viruses on the wound surface.
