How do you heal a scab that is infected?

To heal an infected scab, start by gently cleaning the area with mild soap and water to remove any dirt or debris. Apply an over-the-counter antibiotic ointment to help prevent further infection, and cover it with a sterile bandage. Keep the area clean and dry, and avoid picking at the scab to allow it to heal properly. If signs of infection worsen, such as increased redness, swelling, or pus, consult a healthcare professional.
