Why is antibiotic ointment used when treating wounds?

Basically, wounds are not treated with ointments. When injured, use alcohol or hydrogen peroxide. These substances kill viruses and bacteria that have entered the wound. For wound healing, special ointments can be used that accelerate skin regeneration. They may contain antibiotics so that various microorganisms do not get into the wound and do not begin to develop there. Antibiotic ointments can also be applied to contaminated wounds to destroy the home of dangerous bacteria. Bacteria can cause rotting wounds, so they need to be destroyed.
