Most minor burns can be treated at home with cool water, a simple ointment, and a non-stick bandage. The key is acting quickly in the first few minutes, then keeping the wound clean and moist as it heals. How you treat a burn depends on how deep it goes, so the first step is figuring out what you’re dealing with.
Identify How Serious Your Burn Is
Burns fall into three main categories based on how deep the damage reaches into your skin. Superficial burns (first-degree) only affect the outermost layer. Your skin turns red, may peel, and it hurts, but these are always manageable at home. A mild sunburn or a quick touch to a hot pan falls into this category.
Partial-thickness burns (second-degree) go deeper, damaging the top two layers of skin. These are more painful, can blister, and may cause noticeable changes in skin color or texture beyond simple redness. Many smaller partial-thickness burns can still be treated at home, but they need more careful attention.
Full-thickness burns (third-degree) destroy all layers of skin and can reach the fatty tissue underneath. Because nerve endings are destroyed, these burns paradoxically don’t hurt at the burn site itself. The skin may look charred black, ashen, or gray. These always require professional medical care.
When a Burn Needs Emergency Care
Certain burns should never be treated at home. Get medical help right away if a burn covers a large area of the body, particularly partial-thickness or full-thickness burns larger than about the size of your palm. Burns on the face, hands, feet, genitals, or over major joints like the elbow or knee also need professional treatment regardless of size, because scarring in these areas can limit movement or cause serious complications.
For children under 10 and adults over 50, the threshold is lower. Any full-thickness burn larger than roughly 5% of the body’s surface (about the area of one arm from wrist to elbow) warrants a burn center referral at any age.
Cool the Burn Immediately
Run cool (not cold) water over the burned area for about 10 minutes. This stops the heat from continuing to damage deeper tissue and helps reduce pain and swelling. Use a gentle stream from a faucet if possible.
Do not use ice, ice water, or very cold water. Cold temperatures can cause additional tissue damage on top of the burn itself, making the injury worse rather than better. Room-temperature or slightly cool tap water is ideal.
Skip the Home Remedies
Butter, toothpaste, egg whites, milk, and flour are all common folk remedies for burns. None of them help, and several can actively cause harm. Butter and oils trap heat against the skin. Toothpaste is particularly problematic because its ingredients work against a healing wound in multiple ways: sodium fluoride irritates damaged skin, glycerol can serve as a growth medium for bacteria, and mint flavoring intensifies the burning sensation. Sorbitol, another toothpaste ingredient, acts like sugar in a wound, creating stickiness and debris that encourage infection.
Stick with clean water and the simple wound care steps below.
Cover and Protect the Burn
Once the burn is cooled, apply a thin layer of petroleum jelly or an antibiotic ointment like bacitracin to keep the area moist. Moist wounds heal faster and with less scarring than dry ones. Apply the ointment to a non-stick dressing first, then place the dressing ointment-side down on the burn. You can also buy gauze pads that come pre-coated with petroleum jelly, which simplifies the process.
One thing to watch for: if you use an antibiotic ointment, switch to plain petroleum jelly after about a week. Using topical antibiotics longer than that can cause a skin rash, which is the last thing you need on top of a burn.
Change the dressing daily or whenever it gets wet or dirty. Each time, gently clean the wound with cool water, pat it dry, and reapply ointment and a fresh bandage.
What to Do About Blisters
Blisters are common with partial-thickness burns, and there’s genuine debate even among doctors about the best approach. Some recommend leaving intact blisters alone because the fluid inside provides a natural sterile cushion over the wound. Others prefer to drain them in a sterile setting. What everyone agrees on is that if a blister breaks on its own, the dead skin should be carefully removed because it becomes a source of potential infection.
If your burn has blistered, the safest approach at home is to leave unbroken blisters intact and protect them with a loose non-stick bandage. If a blister pops, gently clean the area, trim any loose dead skin with clean scissors if you can do so safely, and cover it with ointment and a fresh dressing.
Managing Pain During Healing
Superficial burns and partial-thickness burns can be quite painful, especially in the first few days. Over-the-counter pain relievers like ibuprofen or acetaminophen help manage the discomfort and, in the case of ibuprofen, also reduce inflammation. Cooling the burn in the first minutes provides immediate pain relief, but the ongoing ache as the wound heals is best managed with oral pain medication taken as directed on the label.
Keeping the burn covered also reduces pain. Exposed nerve endings are sensitive to air movement and contact, so a moist, bandaged burn typically hurts less than an uncovered one.
How Long Burns Take to Heal
Superficial burns affecting only the top layer of skin generally heal within a week or so. The skin reddens, peels, and regenerates without scarring. Think of a typical sunburn peeling and fading.
Partial-thickness burns take longer, often two to three weeks for more shallow ones, and potentially longer for deeper partial-thickness injuries. These burns carry a higher risk of scarring, especially if they get infected or if the wound dries out repeatedly during healing.
Full-thickness burns don’t heal well on their own because the skin’s regenerative structures have been destroyed. These typically require medical procedures like skin grafting, and recovery can take months.
Reducing Scars After a Burn
Once a burn has healed over, the scar that forms can continue to change for months. Silicone gel sheets are one of the most evidence-backed options for improving burn scars. Applied directly over the healed skin, they help make scars more flexible and smooth. Research has shown significant improvement in scar appearance after about four months of consistent silicone gel use, including in cases of raised (hypertrophic) scars. The exact mechanism isn’t fully understood, but hydration and gentle pressure on the scar tissue both appear to play a role.
Silicone gel products come as adhesive sheets you wear over the scar or as a topical gel you apply like a lotion. Both forms are available over the counter at most pharmacies. For best results, start using them once the wound has fully closed and the skin is no longer raw or open.
Signs of Infection to Watch For
Burns are vulnerable to infection because the skin’s natural barrier has been compromised. Watch for increasing redness that spreads outward from the burn, oozing or discharge (especially if it’s cloudy, greenish, or has an odor), red streaks radiating from the wound, and fever. Any of these signs mean the burn has likely become infected and needs medical attention. Keeping the wound clean, moist, and covered with fresh dressings is the best way to prevent infection from developing in the first place.
