Pure vanilla extract, egg whites, either will provide relief..if it's blistering, painful, doesn't show improvement, see your doctor.
Cool the burn with cool water, as Corey said do not put butter or anything like it, that type of thing will keep the heat in. Aloe Vera, straight from the plant or 100% aloe vera gel, your doctor can prescribe a burn cream called silvadene that will help you best. Keep it covered lightly, don't want it dirty at all. Once it's healing, you can use vitamin E oil to lessen scarring, but only when it's headlining.
