Minor steam burn on finger, about the size of a pea, what can i put on to prevent infection and stop the burning?

Burns: Skin care: You need a barrier to keep it moist, clean, and healthy. So, creams such as a& d or any over the counter burn cream and then gauze bandage until it is healing is good. If the spot gets infected then you need to get to a good health care professional.

Try Vaseline cream: Or vitamin a & d ointment plus neosporin. It should help!
