Most minor burns can be safely treated at home with cool water, basic wound care, and over-the-counter pain relief. First-degree burns (like sunburns) and small second-degree burns with blisters generally heal on their own within five days to two weeks when you care for them properly. The key is acting quickly, keeping the wound clean, and knowing which burns need professional attention.
Cool the Burn Immediately
The single most important thing you can do is run cool or cold water over the burn for at least 10 minutes, ideally 20 minutes. This is the recommendation from the American Red Cross, and it applies to any thermal burn from cooking, steam, hot liquids, or contact with a hot surface. Start as soon as possible after the injury. The water doesn’t need to be ice cold; tap water works well.
If running water isn’t available, a clean, cool compress can substitute. But don’t use ice, ice water, or frozen packs directly on the burn. Extreme cold can damage the already-injured tissue and make things worse. You want to draw heat out of the skin gradually, not shock it.
What Not to Put on a Burn
Butter, toothpaste, and egg whites are old home remedies that do more harm than good. Toothpaste is particularly problematic. Sodium lauryl sulfate (a common foaming agent) irritates damaged skin. Glycerol, another toothpaste ingredient, actually serves as a growth medium for bacteria, meaning it can encourage infection in an open wound. Mint flavoring intensifies the burning sensation. And sorbitol acts like sugar on the wound, creating a sticky surface that traps debris.
Stick with products designed for wound care. Anything from your kitchen cabinet or bathroom counter that wasn’t made for open skin is a risk.
Manage Pain and Swelling
Ibuprofen is typically the best first choice because it reduces both pain and inflammation. Acetaminophen works for pain and fever but won’t address swelling. A combination product containing both is available over the counter for adults and children 12 and older. Don’t exceed 4,000 milligrams of acetaminophen in a 24-hour period from all sources combined, as higher amounts can cause liver damage.
Pain from first-degree burns usually fades within a few days. Second-degree burns with blisters tend to hurt more and longer, partly because the deeper skin layers are exposed to air and pressure. Keeping the burn covered (more on that below) helps reduce this discomfort significantly.
Apply Aloe Vera or Petroleum Jelly
Aloe vera has genuine evidence behind it for minor burns. A systematic review of four clinical trials involving 371 patients found that burns treated with aloe vera healed nearly nine days faster on average than those receiving conventional treatment. You can use pure aloe vera gel from a bottle or directly from a plant leaf. Apply a thin layer to the burn after it has been cooled and gently patted dry. Reapply when the gel dries out or after washing the area.
Petroleum jelly is another solid option. It keeps the wound moist, which promotes healing and reduces scarring. The University of Iowa Health Care recommends it as a simple, effective covering for home burn care. Avoid antibiotic ointments unless a doctor specifically recommends one, as they can cause allergic reactions on damaged skin.
Cover the Burn Properly
After applying aloe or petroleum jelly, cover the burn with a non-stick material. You don’t need specialized medical supplies. Cheesecloth from a grocery store, a clean piece of cotton fabric (an old cotton t-shirt or bedsheet works), or a fragrance-free maxi pad for burns that are oozing all serve as effective dressings. The goal is to protect the wound from friction, dirt, and bacteria without sticking to the raw skin.
Change the dressing once or twice a day. Each time, gently wash the burn with mild soap and water, pat it dry, reapply your ointment or gel, and put on a fresh covering. Clean hands every time you touch the wound.
How to Handle Blisters
This is where most people get conflicting advice. The general rule: leave small, intact blisters alone if they’re smaller than about 6 millimeters (roughly the size of a pencil eraser). These blisters act as a natural bandage and pain barrier, and they’re unlikely to rupture on their own.
Larger blisters, especially thin-walled ones, are a different story. They’re likely to pop on their own, which creates an uncontrolled opening that raises infection risk. If a blister has already ruptured, gently clean the area and remove any loose dead skin, as leaving non-viable tissue on the wound slows healing and invites bacteria. Blisters on fingertips, palms, or the soles of your feet often cause enough discomfort and mobility problems that draining them makes sense. If you’re unsure or uncomfortable doing this yourself, a doctor or urgent care clinic can handle it in minutes.
Watch for Signs of Infection
Even well-cared-for burns can become infected. Check the wound daily for these warning signs:
- Oozing fluid that is cloudy, greenish, or increasing in amount
- Foul smell coming from the wound
- Increasing swelling or redness spreading beyond the burn’s edges
- Fever
- Dizziness or feeling generally unwell
Any of these signs mean the burn needs professional evaluation. Infected burns can escalate quickly, and you may need prescription treatment to clear the infection and prevent scarring.
Which Burns Need Medical Care
Not every burn belongs in the “treat it at home” category. A quick way to estimate burn size: your palm (fingers together) represents roughly 1% of your total body surface area. Use that as a measuring tool.
You should seek medical attention for burns that:
- Cover more than 10% of body surface area in adults ages 10 to 50 (smaller than that in children under 10 or adults over 50, where the threshold drops to 5%)
- Involve the face, hands, feet, genitals, or any major joint like the elbow, knee, or shoulder
- Wrap all the way around a limb, finger, or toe (circumferential burns)
- Appear white, brown, or leathery, which suggests a deeper third-degree burn
- Were caused by chemicals or electricity
What Healing Looks Like
First-degree burns typically heal in five to ten days. The skin may peel as it recovers, similar to a sunburn. No scarring is expected.
Superficial second-degree burns, the kind with clear blisters and pink, weeping skin underneath, generally heal within two weeks. Some pigment changes are possible, meaning the healed skin may be slightly lighter or darker than the surrounding area for months. Scarring is uncommon with proper wound care but becomes more likely if the burn gets infected or if blisters are handled roughly.
During healing, the skin will feel tight and itchy. This is normal and a sign of repair. Moisturizing the area after it has closed (no longer open or weeping) helps with comfort and flexibility. Protect newly healed skin from sun exposure for at least several months, as it burns far more easily than the surrounding skin.
