For a minor burn, the best immediate treatment is cool running water for 20 minutes, followed by a thin layer of antibiotic ointment or petroleum jelly and a non-stick bandage. That simple combination handles most kitchen and household burns effectively. What you put on a burn matters, but so does what you avoid: butter, toothpaste, oil, and ice all make burns worse.
Cool Water First, Everything Else Second
Before you reach for any ointment or cream, run cool (not cold) water over the burn for a full 20 minutes. This step does more than relieve pain. It reduces cell damage at the burn site, improves wound healing, and decreases eventual scarring. The cooling works as long as you start within three hours of the burn, so even if you don’t get to a faucet immediately, it’s still worth doing.
Cold water or ice might seem like a faster solution, but both can injure already-damaged tissue. You want the water comfortably cool, like what you’d wash your hands in on a warm day.
What to Apply After Cooling
Once the burn is cooled and gently patted dry, a topical ointment protects the area from bacteria and keeps the skin moist so it can heal. For most minor burns, an over-the-counter antibiotic ointment containing bacitracin and polymyxin B (sold as Polysporin) is a solid choice. It’s easy to apply, easy to remove when you clean the wound, and safe for sensitive areas like the face. Apply a thin layer and cover it with a non-stick bandage.
Plain petroleum jelly is another option if you don’t have antibiotic ointment on hand. It keeps the wound from drying out, which is the main goal in the early healing phase. The key is maintaining a moist environment under a clean dressing rather than leaving the burn exposed to air.
Aloe Vera
Aloe vera gel is one of the most popular home remedies for burns, and there’s some basis for it. The gel contains compounds that promote collagen production, support new blood vessel growth, and may have mild antimicrobial properties. That said, the clinical evidence is limited, and most studies on aloe for burns have significant design flaws.
If you use aloe, stick to a commercially prepared gel rather than slicing open a plant leaf. Homemade aloe preparations aren’t sterile and can introduce bacteria into a wound. Test it on a small patch of unburned skin first, since aloe can trigger allergic reactions in some people, particularly those who are also allergic to onions or garlic.
What Never to Put on a Burn
Butter, toothpaste, cooking oil, and egg whites are all common folk remedies that actively harm burn wounds. These substances trap heat against the skin, which deepens the injury. They can also irritate raw tissue and introduce bacteria. If someone has already applied one of these, gently wash it off with cool water before applying an appropriate ointment.
Ice and ice water fall into the same category. While they numb the pain temporarily, they constrict blood vessels in the area and can cause frostbite-like damage on top of the burn.
How to Bandage a Burn
After applying ointment, cover the burn with a non-stick dressing. Regular gauze by itself tends to stick to the wound and tears away new skin when you remove it. Non-adherent mesh dressings or foam dressings are better choices and are available at most pharmacies.
For burns that are oozing a lot of fluid, foam or alginate dressings absorb excess moisture while keeping the wound bed moist. Change the dressing often enough to manage oozing but not so frequently that you’re disturbing the healing surface. For most minor burns, once or twice a day works well. Each time you change the bandage, gently clean the wound with mild soap and water, reapply ointment, and re-cover it.
Keeping the wound covered reduces exposure to bacteria that can cause infection. Signs of infection include increasing redness, swelling, warmth spreading beyond the burn edges, pus, or a fever developing days after the injury.
Managing Burn Pain
Burns hurt, and the pain can last for days. Over-the-counter pain relievers help significantly. Acetaminophen (Tylenol) works well at 1,000 mg every six hours, with a maximum of 4,000 mg per day. Ibuprofen at 400 mg every eight hours or naproxen at 500 mg every 12 hours are also effective and have the added benefit of reducing inflammation at the burn site.
Cool compresses applied over the bandage can provide additional relief between doses. If the pain keeps you from sleeping or isn’t controlled by these options, that’s a signal the burn may be more serious than it looks.
Know Your Burn’s Severity
What you can safely treat at home depends on how deep the burn goes. First-degree burns affect only the outer layer of skin. They look like a sunburn: dry, red, and painful. These heal on their own in a few days with basic care.
Second-degree burns go deeper. The skin is moist, may blister, and is extremely painful. Small second-degree burns (smaller than about 3 inches across) can often be managed at home with the ointment-and-bandage approach described above, though they take two to three weeks to heal.
Third-degree burns destroy the full thickness of the skin. They can appear white, black, brown, or waxy, and are often less painful than second-degree burns because the nerves in the skin have been destroyed. These burns cannot heal on their own and always need professional treatment. Burns that wrap around a finger, hand, foot, or joint, burns on the face or genitals, and any burn larger than your palm also warrant medical attention regardless of depth.
