For a minor burn, the best immediate treatment is cool running water for at least 10 to 20 minutes, followed by a thin layer of antibiotic ointment or petroleum jelly and a non-stick bandage. Most small burns from cooking, curling irons, or brief contact with hot surfaces heal well at home with simple supplies you likely already have.
What you put on a burn depends on how severe it is, so knowing the difference matters before you reach for anything in your medicine cabinet.
How to Tell if You Can Treat It at Home
First-degree burns affect only the outermost layer of skin. They look dry and red, similar to a sunburn, and they hurt. These are the most common kitchen and household burns, and they’re safe to treat on your own.
Second-degree burns go deeper into the skin and produce blisters. The skin looks moist and red, and the pain is more intense. Small second-degree burns (smaller than about 3 inches across) in non-sensitive areas can often be managed at home, but larger ones or those on the face, hands, feet, groin, or over a joint need professional care.
Third-degree burns destroy the full thickness of the skin. They can appear white, black, brown, or red, and the surface looks dry or leathery. Surprisingly, they’re often less painful than second-degree burns because the nerves in the skin have been destroyed. These always require emergency treatment.
Cool Water First, Always
The single most effective thing you can do for a fresh burn is hold it under cool running water. The International Liaison Committee on Resuscitation recommends this as the standard first-aid step for thermal burns in both adults and children. Start as soon as possible after the injury.
Use cool water, not ice-cold. There’s no firm consensus on the exact ideal duration, but most guidelines suggest 10 to 20 minutes. The goal is to pull heat out of the tissue and limit how deep the damage goes. If you can’t get to a faucet, a cool, clean wet cloth held against the burn works as a temporary substitute. Avoid submerging the burn in ice water or applying ice cubes directly, as extreme cold can cause additional tissue damage on already-injured skin.
What to Apply After Cooling
Once the burn is cooled, gently pat the area dry with a clean cloth. Then apply a thin layer of one of these options:
- Petroleum jelly (Vaseline): This is the simplest and most widely available option. It keeps the wound moist, which promotes faster healing and reduces scarring. Reapply it each time you change the bandage.
- Antibiotic ointment: A basic over-the-counter antibiotic ointment adds a layer of infection protection on top of keeping the wound moist. It’s a good choice if the skin is broken or blistered.
- Aloe vera: Pure aloe vera gel (not the bright green kind with added fragrances) can soothe first-degree burns and help with mild inflammation. It’s best suited for sunburns and very superficial burns rather than anything with broken skin.
- Medical-grade honey: Manuka honey and other medical-grade honey products have genuine antibacterial properties and are used in clinical wound care. Look for products specifically labeled as medical-grade or sterile if you go this route. Regular grocery store honey is not sterile enough for open wounds.
After applying your ointment of choice, cover the burn with a non-stick bandage or dressing. Fine mesh gauze designed for wounds works well. Avoid plain dry gauze if you can, because it sticks to the wound as it heals and causes pain and tissue damage when you pull it off. Foam dressings and hydrogel pads are other good options available at most pharmacies.
What Not to Put on a Burn
Some of the most popular home remedies for burns actually make things worse. Butter, milk, eggs, and flour all trap heat in the skin and introduce bacteria directly into the wound. Butter in particular is one of the most persistent myths in burn care, and it does the opposite of what you want.
Toothpaste is another common but harmful remedy. It contains ingredients like sodium lauryl sulfate, which irritates damaged skin, and sorbitol, a sugar-like compound that can encourage bacterial growth in the wound. Mint-based toothpaste adds to the burning sensation rather than relieving it.
Ice and ice-cold water are also problematic. While cooling is essential, extreme cold constricts blood vessels and can cause frostbite-like damage to skin that’s already compromised. Stick to cool (not cold) running water.
Managing Pain at Home
Burns hurt, especially in the first few days. Over-the-counter pain relievers work well for minor burns. Ibuprofen is particularly helpful because it reduces both pain and inflammation. Acetaminophen is a good alternative if you can’t take ibuprofen due to kidney concerns or stomach sensitivity.
Keeping the burn covered and moist also reduces pain significantly compared to leaving it exposed to air. If the bandage itself sticks or causes discomfort during changes, try wetting it with clean water before removing it to loosen the adhesion.
How to Tell if a Burn Is Getting Infected
Even well-treated burns can develop infections, so keep an eye on the healing process over the first week or two. Normal healing involves some redness and mild swelling that gradually improves. Infection looks different.
Watch for pain that gets worse over time rather than better, green or yellow discharge from the wound, a foul smell, or red streaks spreading outward from the burn. Fever, chills, or nausea alongside a worsening burn are signs that the infection may be spreading beyond the wound itself. Any of these warrant prompt medical attention.
Caring for Blisters
If your burn produces blisters, resist the urge to pop them. Intact blisters act as a natural sterile bandage, protecting the raw skin underneath from bacteria. Cover them gently with a non-stick dressing and let them heal on their own.
If a blister breaks on its own, clean the area gently with mild soap and water, apply antibiotic ointment or petroleum jelly, and cover it with a fresh bandage. Leave the loose skin in place rather than peeling it off, as it still provides some protection to the healing tissue beneath it. Change the dressing daily or whenever it gets wet or dirty.
