For minor, uncomplicated burns, Neosporin (Triple Antibiotic Ointment) is a suitable treatment option. Other potential treatments include bacitracin, Polysporin, or petroleum jelly.
You should apply the ointment or cream and cover the wound with a non-stick dressing or pad such as Telfa (not a cotton ball).
For more severe burns, it's important to seek medical attention immediately.
