I was watching someone administering first aid treatment to a child who had a scratch. What I saw is the mother putting first aid cream, an antibiotic ointment, directly on the wound. That can be very painful to the child or injured person.
Here is a very simple technique so as not to touch the cut. Run a strip of the antibiotic ointment directly on the bandaid itself. The ointment will spread out on it's own as you then apply the bandaid to the cut.
