First, please ensure the area has been thoroughly rinsed with cool water. Regarding your options, Fucibet cream (containing fusidic acid and a steroid) should be avoided, as steroids can delay healing and increase infection risk on burns. Betadine (povidone-iodine) is an antiseptic that can prevent infection, but it can sometimes dry out or irritate healing tissue. For gentle healing, keeping the area clean and applying a plain petroleum jelly under a sterile bandage is often best. If the burn is deep, blistered, or painful, please see a doctor right away to ensure it heals safely.
