The single most important thing to apply to a burn is cool, running water for at least 20 minutes. After that initial cooling, what you put on the burn depends on how deep it is. Most kitchen and household burns are superficial or partial-thickness injuries that heal well at home with the right topical care. Here’s what actually works, what to avoid, and how to protect the wound as it heals.
Cool Water First, Everything Else Second
Before you reach for any ointment or cream, run cool (not ice-cold) water over the burn for a full 20 minutes. This is the single most evidence-backed step in burn first aid, and it does more for healing and pain than any product you’ll apply afterward. The water should feel comfortable, not frigid. Start as soon as possible after the injury.
While the burn is under water, remove any clothing, jewelry, or accessories near the area before swelling starts. Don’t try to peel away anything that’s stuck to the skin.
Know Which Burns You Can Treat at Home
What you apply next depends on the severity of the burn. Superficial burns damage only the top layer of skin. They turn red, may peel, and hurt but don’t blister. These always heal on their own with basic care.
Partial-thickness burns go deeper into the second layer of skin. They blister, cause noticeable color or texture changes, and are often quite painful. Small partial-thickness burns (smaller than about 3 inches across) can usually be managed at home, but larger ones need medical attention.
Full-thickness burns destroy all layers of skin and reach the fat underneath. The skin may look charred, ashen, or waxy. Because nerve endings are destroyed, these burns often don’t hurt at the site itself. Full-thickness burns always require professional treatment.
What to Apply After Cooling
Once you’ve cooled the burn for 20 minutes, gently pat the area dry and apply one of these options:
Aloe vera gel. Evidence supports aloe vera for superficial and partial-thickness burns. It can shorten healing time and increase the rate of new skin growth compared to conventional treatments. Use pure aloe vera gel, not a lotion that contains aloe as one ingredient among many fragrances and additives. You can apply it several times a day as the burn heals.
Petrolatum (petroleum jelly). A thin layer of plain petroleum jelly keeps the wound moist, which helps new skin form faster. It’s inexpensive, widely available, and doesn’t contain ingredients that could irritate raw skin. Reapply it each time you change the dressing.
Antibiotic ointment. Over-the-counter antibiotic ointments provide a moisture barrier and may help prevent surface infection in minor burns. Apply a thin layer and cover with a non-stick bandage.
For larger or more serious partial-thickness burns treated in a clinical setting, silver sulfadiazine cream is the most commonly used topical agent. It has a long track record in burn centers and reduces bacterial colonization on wound surfaces. However, for small burns at home, simpler options like petroleum jelly or aloe vera work well and don’t require a prescription.
Covering and Protecting the Burn
After applying your chosen ointment or gel, cover the burn with a non-stick gauze pad. Regular gauze or adhesive bandages can stick to the raw skin and tear new tissue when you remove them. Non-stick wound pads are sold at any pharmacy, often labeled as “non-adherent” dressings.
Wrap the non-stick pad loosely with rolled gauze or medical tape around the edges. The goal is protection from friction and bacteria, not compression. Change the dressing once a day, or sooner if it gets wet or dirty. Each time, gently clean the burn with mild soap and water, pat dry, reapply ointment, and re-cover with fresh gauze.
If you have blisters, leave them intact. Unbroken blisters act as a natural sterile barrier. If a blister pops on its own, clean the area, apply petroleum jelly or antibiotic ointment, and cover it.
Managing Pain
Burns hurt most in the first few days. Over-the-counter anti-inflammatory pain relievers like ibuprofen (400 mg every 8 hours) or naproxen (500 mg every 12 hours) help reduce both pain and the swelling that drives it. Acetaminophen (1,000 mg every 6 hours, no more than 4,000 mg in 24 hours) is a good alternative if you can’t take anti-inflammatories due to stomach or kidney issues.
Keeping the burn moist with petroleum jelly or aloe also reduces pain. Dry, exposed burns are significantly more painful than covered, moisturized ones.
What Not to Put on a Burn
Ice or ice water. Ice restricts blood flow to the injured area, which slows healing rather than helping it. It can also numb the skin enough that you don’t notice cold damage building up, potentially causing frostnip or tissue injury on top of the burn.
Butter, cooking oil, or mayonnaise. Greasy food products trap heat in the wound, slowing the cooling process your skin needs. They also introduce bacteria directly into broken skin, raising the risk of infection.
Toothpaste. Despite the persistent home remedy, toothpaste irritates burn wounds, increases pain, and raises the risk of infection and scarring. None of its ingredients have properties that promote healing.
In general, avoid anything not designed for open wounds: essential oils, egg whites, vinegar, and other folk remedies can all introduce irritants or bacteria.
Signs of Infection to Watch For
Even with good care, burns can become infected. Watch for increasing redness that spreads beyond the edges of the burn into surrounding healthy skin, especially if the area also feels warm, firm, or increasingly tender. A partial-thickness burn that appears to be getting deeper rather than healing is another warning sign.
Pus, cloudy discharge, or a foul smell from the wound all point toward infection. Fever or feeling generally unwell alongside a burn that looks worse instead of better also warrants prompt medical evaluation.
Burns That Need Professional Care
Some burns should not be managed at home regardless of what you apply. Seek professional care for burns that involve the face, hands, feet, genitals, or major joints. Burns that wrap all the way around an arm, leg, or finger also need medical attention because swelling can cut off circulation.
Size matters too. Partial-thickness or deeper burns covering more than 20% of the body in adults (or more than 10% in children under 10 or adults over 50) meet criteria for burn center referral. Any full-thickness burn larger than about the size of your palm qualifies as well. Chemical burns, electrical burns, and burns combined with smoke inhalation all require emergency evaluation regardless of how the skin looks on the surface.
