Introduction
Povidone-iodine has a relatively good disinfecting effect. Both povidone-iodine and complexed iodine are common disinfectants; however, complexed iodine is a surfactant that forms unstable compounds through complexation. When used for disinfection, its effectiveness is not very good. In contrast, povidone-iodine offers superior disinfection performance and is a commonly used broad-spectrum antimicrobial agent.

Both povidone-iodine and complex iodine are common disinfectants. However, complex iodine is a surfactant that forms unstable compounds through complexation. When used for disinfection, its effectiveness is relatively poor. In contrast, povidone-iodine offers superior disinfection performance. It is a commonly used broad-spectrum antimicrobial agent capable of killing fungi, bacteria, and other microorganisms. It is widely applied for skin disinfection, burns, and similar conditions, providing effective disinfection with broad clinical utility.
Povidone-iodine is primarily formulated using water as the solvent and is non-irritating to skin and wounds. If there is a wound on the skin, povidone-iodine can be used for disinfection to prevent bacterial infection and promote wound healing. Additionally, it has minimal irritation and generally does not cause noticeable discomfort to the wound site.
Moreover, after disinfecting with povidone-iodine, proper local skin care should be maintained. The treated area should avoid contact with water for a period of time to prevent potential skin infections.
