For a minor burn, cool running water and a simple layer of aloe vera gel or petroleum jelly are the most effective first steps. What you put on a burn in the first few minutes matters, but so does what you avoid. Butter, toothpaste, oil, and ice all make burns worse, not better.
Cool the Burn With Running Water First
Before you put anything on a burn, hold it under cool (not cold) running water for at least 10 to 20 minutes. This is the single most important thing you can do. Cool water draws heat out of the deeper layers of skin and limits tissue damage. Cold water or ice, on the other hand, can constrict blood vessels and actually worsen the injury. Room-temperature or slightly cool tap water is ideal.
If running water isn’t available, a clean, cool, damp cloth held gently against the burn can help, though it’s less effective. Don’t submerge a large burn in cold water, as this can drop body temperature dangerously, especially in children.
What to Apply After Cooling
Once the burn has been cooled and gently patted dry, you have a few good options for what to put on it.
Aloe vera gel is one of the best-studied home treatments for minor burns. A meta-analysis of randomized controlled trials in the Journal of Burn Care & Research found that aloe vera reduced healing time by nearly four days compared to other topical treatments in second-degree burns, without increasing the risk of infection. Look for pure aloe vera gel without added fragrances, alcohol, or dyes. If you have an aloe plant, the fresh gel from a leaf works well.
Petroleum jelly (like Vaseline) is another reliable choice. It keeps the wound moist, which promotes healing and reduces pain from air exposure. Apply a thin layer and reapply after cleaning the burn. It doesn’t have antibacterial properties on its own, but it creates a protective barrier.
Medical-grade honey has antibacterial properties and is used in clinical wound care. Products containing medical-grade honey gel have been shown to reduce bacterial counts on burn wounds to levels comparable to silver-based wound treatments. Regular grocery store honey isn’t sterile and isn’t recommended for open wounds. If you want to try honey, look for products specifically labeled for wound care.
Over-the-counter antibiotic ointments like bacitracin can help prevent infection on small, superficial burns. Apply a thin layer before covering with a bandage. Avoid anything with neomycin if you’ve had allergic reactions to topical antibiotics in the past.
How to Bandage a Burn Properly
After applying your chosen ointment or gel, cover the burn with a non-stick (non-adherent) dressing or a petroleum-based gauze pad. Never place dry gauze directly on an open burn, as it will stick to the wound and tear healing skin when you remove it. Layer dry sterile gauze over the non-stick dressing, then secure everything with medical tape or a gauze roll. If you’re wrapping a finger, hand, or limb, start wrapping from the point farthest from your body and work inward. Keep it snug but not tight, since swelling is common and a tight wrap can cut off circulation.
Change the dressing once a day or whenever it gets wet or dirty. Each time, gently clean the burn with mild soap and water, pat it dry, reapply your topical treatment, and re-bandage with fresh materials.
Managing Pain at Home
Burns hurt, and the pain can linger for days. Over-the-counter pain relievers are the standard approach. Ibuprofen works well because it reduces both pain and inflammation. Acetaminophen is a good alternative if you can’t take ibuprofen. You can also alternate between the two for more consistent relief. Keep the burn elevated when possible, as this reduces throbbing. Reapplying a thin layer of aloe vera or petroleum jelly also helps by keeping air off exposed nerve endings, though research on aloe’s direct pain-relieving effects remains inconclusive.
What Not to Put on a Burn
Some of the most common home remedies for burns are the worst things you can use. Butter, cooking oil, and toothpaste all trap heat inside the wound. Instead of cooling the burn, they act as insulation, keeping the skin cooking from the inside and causing deeper damage. They can also introduce bacteria into a wound that’s already vulnerable.
Ice and ice water are equally harmful. While they feel soothing initially, extreme cold damages already-injured tissue and can cause frostbite on skin that’s lost its protective barrier. Stick with cool water only. Egg whites, vinegar, and essential oils are other folk remedies that have no evidence of benefit and carry real risks of infection or chemical irritation.
Know Your Burn’s Severity
Home treatment works well for first-degree burns (red, painful skin without blisters, like a mild sunburn) and small second-degree burns (blistered, very painful, swollen skin). These are the burns most people get from touching a hot pan, splashing hot water, or grabbing a curling iron.
Some burns need professional care. The American Burn Association’s referral criteria flag several situations that go beyond what home treatment can handle:
- Burns on the face, hands, feet, genitals, or over joints carry higher risks of scarring and functional problems.
- Burns covering a large area, roughly larger than the size of your palm, especially in children under 10 or adults over 50.
- Third-degree burns of any size. These look white, brown, or leathery and may not hurt because nerve endings have been destroyed.
- Electrical or chemical burns, which often cause deeper damage than what’s visible on the surface.
If a burn wraps all the way around a finger, hand, or limb, that also needs immediate medical attention because swelling can cut off blood flow.
Tetanus Risk With Burns
Burns are classified as “dirty or major wounds” under CDC guidelines for tetanus prevention. If your last tetanus shot was five or more years ago, a booster is recommended after a burn injury. If you’re unsure of your vaccination history or haven’t completed the full tetanus series, you may also need a dose of tetanus immune globulin for immediate protection. This is especially relevant for burns that break the skin or involve contact with a contaminated surface.
Signs of Infection to Watch For
Even well-treated burns can get infected. In the days after a burn, watch for increasing redness spreading outward from the wound’s edges, streaks radiating out from the burn, oozing that turns yellow or green, increasing pain instead of gradually decreasing pain, or a fever. Infection typically shows up two to three days after the injury. If you notice any of these signs, the burn needs medical evaluation and likely a course of antibiotics.
