What is a one-sentence summary of the following article?
Ointments seal the burn, and may actually prevent healing if you apply them too soon. For first-degree burns, wait 24 hours before you apply any burn care or other ointments. If you are not near a medical facility and you have a second-degree burn, apply bacitracin ointment (an antibiotic) to the burn to prevent infection as you get to treatment. This is the only situation in which you should apply bacitracin to burned skin. Benzocaine is a local anesthetic that numbs nerve endings in the skin, providing relief from burn pain. The pharmacy may have any of a variety of benzocaine brands such as Anacaine, Chiggerex, Mandelay, Medicone, Outgro, or Solarcaine. Furthermore, these products are available in a wide variety of applications: cream, spray, liquid, gel, ointment, or wax. Read the instructions on the package to learn the correct application method and dosage. Make sure not to overuse benzocaine, as it soaks into the skin more easily than some other local anesthetics. You can relieve some of the pain from a minor burn by taking an over-the-counter pain reliever. An oral NSAID (nonsteroidal anti-inflammatory drug) such as ibuprofen or naproxen will help relieve pain and inflammation from the burn. Follow all dosing instructions on the packaging. Take the smallest dose that is effective at relieving your pain. If cold water doesn't make the pain diminish, shaving cream is a surprisingly effective solution! Shaving creams like Barbasol contain a chemical called triethanolamine. Triethanolamine is an active ingredient in Biatine, a prescription cream used to treat even severe burns in hospital settings. Just spread it over the affected skin and leave it alone until the pain goes down.  Avoid mentholated shaving creams, as they may cause further irritation. This should only be considered when you have a first-degree burn. Do not attempt this method with a burn that is any more severe than a sunburn.
Do not apply burn ointments for the first 24 hours. Find over-the-counter benzocaine products. Take an over-the-counter pain reliever. Spread shaving cream over the burn site.
