For a fresh burn, the first thing to reach for isn’t a cream or ointment. It’s cool running water. Hold the burned area under a gentle stream of cool (not cold) water for about 10 minutes. This is the single most effective immediate treatment, and it does more to reduce pain and limit tissue damage than any product you apply afterward.
Once the burn is cooled, what you put on it depends on how severe it is. Most kitchen and household burns are minor enough to treat at home with a few simple supplies.
Cool Water First, Then Assess
Running cool water over the burn for 10 minutes draws heat out of the deeper layers of skin and slows the inflammatory response. Cold water or ice can actually make the injury worse by constricting blood vessels and damaging tissue further, so keep the temperature comfortable. After cooling, gently pat the area dry with a clean cloth and take a closer look at what you’re dealing with.
A first-degree burn looks like a sunburn: dry, red, and painful, with no blisters. The damage is only in the outermost layer of skin, and it heals on its own within a week. A second-degree burn goes deeper. You’ll see blisters, the skin looks moist and red, and it’s extremely painful to touch. Third-degree burns destroy the full thickness of the skin and may appear white, brown, or black. They’re often less painful than second-degree burns because the nerves themselves are destroyed. Any burn that looks white, waxy, or charred needs emergency care.
What to Apply on a Minor Burn
For first-degree burns and small second-degree burns (smaller than about 3 inches across), here’s what works:
Petroleum jelly is the go-to topical treatment. It keeps the wound moist, which is critical for healing, and it protects raw skin from friction and bacteria. You might assume antibiotic ointment would be better, but research shows antibiotic ointments offer no advantage over plain petroleum jelly for wound healing. They do, however, carry a meaningful risk of causing contact dermatitis, an allergic skin reaction that can make things worse. Many dermatologists now use only petroleum-based ointments for wound care and skip the antibiotics entirely.
Aloe vera is a reasonable option, especially for first-degree burns. A systematic review of clinical trials found that aloe vera shortened burn healing time by nearly 9 days compared to conventional treatments and improved healing rates for first- and second-degree burns. Look for pure aloe vera gel rather than products with added fragrances or alcohol, which can sting and dry out the skin. If you have an aloe plant, the gel straight from a leaf works well.
Apply a thin layer of petroleum jelly or aloe vera to the burn two to three times a day, or whenever the area feels dry.
How to Cover and Protect It
After applying petroleum jelly or aloe, cover the burn with a non-stick dressing. Regular gauze or adhesive bandages can stick to the raw surface and tear new skin when you change them. Non-stick or silicone-based wound pads are widely available at pharmacies and are specifically designed to protect healing tissue without adhering to it. Secure the pad loosely with medical tape or a gauze wrap.
Change the dressing once or twice a day, or sooner if it gets wet or dirty. Each time, gently clean the area with cool water, pat dry, and reapply your ointment before putting on a fresh dressing. For burns that are weeping fluid, you may need to change the dressing more often. As healing progresses over several days and the wound dries out, you can switch to less frequent changes.
Managing the Pain
Burns hurt, sometimes intensely, and the pain can linger for days. Over-the-counter pain relievers help considerably. Ibuprofen works well because it reduces both pain and inflammation. A standard dose is 400 mg every 8 hours. Acetaminophen is an alternative if you can’t take ibuprofen, at 1,000 mg every 6 hours, but don’t exceed 4,000 mg in a 24-hour period.
Taking pain relief on a regular schedule for the first day or two, rather than waiting until the pain becomes unbearable, keeps it more manageable overall. After that, you can taper to as-needed use as the burn starts to heal.
What Not to Put on a Burn
Several popular home remedies make burns worse. Butter and cooking oils trap heat in the skin, deepening the injury. Toothpaste contains chemicals that irritate raw tissue. Ice and ice water constrict blood flow and can cause frostbite on already damaged skin. Egg whites carry a risk of bacterial infection. None of these have any evidence supporting their use, and all of them can delay healing or cause additional harm.
You should also leave blisters intact. They’re your body’s natural bandage, protecting the raw skin underneath from infection. If a blister breaks on its own, gently clean the area, apply petroleum jelly, and cover it with a non-stick dressing.
Signs the Burn Needs Medical Attention
Most small first-degree burns and minor second-degree burns heal fine at home within one to three weeks. But certain burns need professional care. Seek medical attention if the burn is larger than 3 inches across, or if it’s on the face, hands, feet, groin, or over a joint. Burns that wrap all the way around a finger, arm, or leg also need evaluation because swelling can cut off circulation.
Any burn that appears white, leathery, or charred is a third-degree burn and requires emergency treatment. The same goes for chemical burns and electrical burns, which often cause deeper damage than what’s visible on the surface.
During the healing process, watch for signs of infection: increasing redness spreading outward from the burn, oozing or streaking from the wound, worsening pain after the first couple of days, or fever. These are signals that bacteria have taken hold and you need medical treatment.
