For a minor burn, cool it under room-temperature running water for 10 to 20 minutes, then apply a thin layer of petroleum jelly and cover it with a non-stick bandage. That simple routine is the current standard of care, and it works better than most of the home remedies people reach for. What you put on a burn in the first few minutes matters, but so does what you avoid putting on it.
Cool the Burn First
Before you apply anything, hold the burned skin under cool (not cold) running water. Room-temperature tap water is ideal. Keep it there for at least 10 minutes, and up to 20 if the pain is still intense. This draws heat out of the deeper layers of skin and limits the damage from spreading.
Don’t use ice, ice water, or frozen packs. Extreme cold constricts blood vessels and can injure already-damaged tissue, turning a minor burn into something worse. Once you’ve cooled the area, gently pat it dry with a clean cloth.
What to Apply After Cooling
Plain petroleum jelly is the best thing to put on a minor burn. It keeps the wound moist, which is essential for skin to heal properly, and it doesn’t contain ingredients that can trigger allergic reactions. A thin, even layer is all you need. Reapply it every time you change the bandage.
Many people reach for antibiotic ointments, but research shows they offer no healing advantage over plain petroleum jelly. Ingredients commonly found in antibiotic ointments, like neomycin and bacitracin, are known to cause contact dermatitis, which means they can actually irritate the wound. The infection rate for clean wounds is already very low (under 1%), so the antibiotics aren’t doing much preventive work either. Stick with petroleum jelly unless a doctor tells you otherwise.
After applying the ointment, cover the burn with a non-stick gauze pad and secure it loosely with medical tape or a rolled bandage. Non-stick dressings are important because regular gauze can bond to the raw wound surface and tear new skin when you remove it. You can find non-stick pads at any pharmacy. Change the dressing once a day, or sooner if it gets wet or dirty.
Know What Type of Burn You’re Treating
Not every burn can be managed at home. The depth of the injury determines what kind of care it needs.
- First-degree (superficial): Only the outer layer of skin is affected. You’ll see redness or discoloration, and it will hurt, but there are no blisters. A sunburn is a common example. These heal on their own in about a week with basic wound care.
- Second-degree (partial-thickness): Both the outer layer and the layer beneath it are damaged. The skin may look red, white, or splotchy, and blisters often form. Pain can be severe. Small second-degree burns (smaller than about 3 inches across) can usually be treated at home. Larger ones need medical attention.
- Third-degree (full-thickness): All layers of skin are destroyed, sometimes extending into fat and muscle. The burned area may appear black, brown, or white and look leathery. Because nerves are destroyed, there may be surprisingly little pain. Third-degree burns always require emergency care.
The home treatment described in this article applies to first-degree burns and small second-degree burns only.
What Not to Put on a Burn
Butter, cooking oil, coconut oil, and toothpaste are among the most common things people apply to burns, and all of them make the injury worse. These substances trap heat inside the skin, essentially letting the burn keep cooking underneath a greasy seal. They also introduce bacteria and irritants to an open wound.
Other things to avoid: egg whites, honey (unless medical-grade and recommended by a provider), aloe vera gel with added fragrances or alcohol, and any adhesive bandage placed directly on the burn surface. If you don’t have petroleum jelly and non-stick gauze on hand, a clean, dry cloth loosely draped over the burn is better than improvising with kitchen ingredients.
Managing Pain
Burns hurt, and the pain from a second-degree burn in particular can be intense for the first few days. Over-the-counter pain relievers work well for minor burns. Ibuprofen reduces both pain and inflammation, while acetaminophen handles pain alone. You can alternate the two if one isn’t enough on its own. Take ibuprofen with food to protect your stomach.
Keeping the burn moist and covered also reduces pain. Exposed nerve endings dry out and become more sensitive to air currents and contact, so a well-dressed wound simply hurts less than an uncovered one.
Watching for Infection
Even with good care, burns can become infected. Check the wound each time you change the dressing. Signs that something is going wrong include increasing redness or warmth spreading outward from the burn into surrounding healthy skin, swelling and tenderness that gets worse rather than better, pus or cloudy drainage, and a fever. A partial-thickness burn that suddenly looks deeper or darker may be converting to a more severe injury due to infection.
Keep in mind that some redness around a healing burn is normal. What you’re looking for is a worsening pattern: redness that expands, pain that intensifies after the first couple of days, or skin that feels hot and firm around the edges.
Burns That Need Professional Care
Certain burns should not be treated at home regardless of how small they look. Burns on the face, hands, feet, genitals, or over major joints (elbows, knees, shoulders) carry a higher risk of complications and scarring. Second- or third-degree burns larger than your palm also warrant a trip to the emergency room.
Children under 10 and adults over 50 have thinner skin and slower healing, so the threshold for seeking care is lower. Any third-degree burn, even a small one, needs professional treatment.
Electrical and chemical burns are a different category entirely. Electrical burns can damage muscle, blood vessels, and nerves far beneath the skin, making the visible wound a poor indicator of the real injury. Anyone who has been shocked by an electrical source should be evaluated by a medical professional, even if the skin burn appears minor. For chemical burns, flush the area with large amounts of running water for at least 20 minutes before doing anything else.
Tetanus and Burns
Burns are classified as “dirty” wounds by the CDC, which means they carry a risk of tetanus. If your last tetanus shot was five or more years ago, you may need a booster. This is especially relevant for burns caused by rusty metal, outdoor cooking equipment, or anything contaminated with soil. Check your vaccination records or ask a pharmacist to look them up if you’re unsure.
