this really depends on what type of infection and how severe it is. typically if you have a small cut you can wash with soap and water and then apply a triple antibiotic ointment. if the infection on the skin appears red warm to the touch painful or oozing you will need to see your health care provider. skin infections can be very difficult to treat and can require prescription antibiotics if not taken seriously.
