For a fresh minor burn, the first thing to put on it is cool running water for about 10 minutes. After that, a thin layer of petroleum jelly or pure aloe vera gel protects the wound and supports healing. What you don’t put on a burn matters just as much: butter, toothpaste, and oils can trap heat in your skin and increase infection risk.
The right treatment depends on how severe the burn is, so here’s a practical walkthrough of what works, what doesn’t, and how to care for a burn as it heals.
Cool Water First, Always
Before you put anything on a burn, run cool (not cold) water over the area for about 10 minutes. This stops the heat from continuing to damage deeper layers of skin. Ice, ice water, or very cold water can actually make the injury worse by constricting blood vessels and causing further tissue damage. Room-temperature to slightly cool tap water is ideal.
If the burn is on a spot that’s hard to hold under a faucet, you can soak a clean cloth in cool water and gently drape it over the area. Just don’t leave a wet cloth sitting on the burn for long stretches, since prolonged cooling can lower your body temperature.
Know What Kind of Burn You’re Treating
Not all burns can be managed at home, and what you put on a burn depends on its depth.
- First-degree burns affect only the outer layer of skin. They look dry and red, similar to a sunburn, and they’re painful. These heal well at home.
- Second-degree burns go deeper into the skin. They’re moist, red, may blister, and are extremely painful. Small second-degree burns (smaller than about 3 inches across) can often be treated at home, but larger ones or burns on the face, hands, feet, groin, or joints need professional care.
- Third-degree burns destroy the full thickness of skin. They can appear white, black, brown, or red, and they feel dry. Counterintuitively, they may hurt less because the nerve endings are destroyed. These always require emergency medical treatment. Do not put anything on a third-degree burn other than a clean, dry covering while you get to a hospital.
What to Apply After Cooling
Once you’ve cooled the burn, gently pat the area dry with a clean cloth. Then apply a thin layer of one of these:
Petroleum jelly is one of the simplest and most effective options. It keeps the burn moist, which is what wounds need to heal properly. You don’t need anything medicated. MedlinePlus specifically notes that the ointment you use does not need to contain antibiotics, and that some antibiotic ointments can actually cause allergic reactions on burned skin.
Pure aloe vera gel is another solid choice. A systematic review of clinical studies found that aloe vera shortened burn healing time by nearly 9 days compared to standard treatment, and it increased the rate of successful healing in first- and second-degree burns. Look for 100% aloe vera gel without added fragrances, dyes, or alcohol. If you have an aloe plant, fresh gel straight from the leaf works well.
Reapply your chosen ointment two to three times a day, or whenever you change the dressing.
What Not to Put on a Burn
Some of the most popular home remedies for burns are the worst things you can use.
Toothpaste is a common suggestion that can cause real harm. The ingredients in toothpaste, including sodium fluoride, seal heat underneath your skin layers rather than drawing it out. This causes more damage beneath the surface. Even fluoride-free or baking soda formulas will only prolong healing. Toothpaste also introduces bacteria to the wound.
Butter and cooking oils (including coconut oil and olive oil) have the same problem. They create a barrier that traps heat against damaged tissue. They’re also not sterile, which raises your infection risk on skin that’s lost its natural protective barrier.
Ice or ice water applied directly to the burn can cause frostbite on already-damaged skin and restrict blood flow to the area right when it needs circulation for healing.
How to Cover and Protect the Burn
After applying ointment, you want a dressing that protects the burn without sticking to it. Pulling an adhered bandage off a healing burn is painful and tears new tissue.
For most minor burns treated at home, a non-stick gauze pad secured with medical tape works well. You can find these at any pharmacy, often labeled as “non-adherent” pads. Change the dressing once a day or whenever it gets wet or dirty.
Hydrogel dressings are a step up if you want more comfort. They’re mostly water-based, provide a cooling sensation, and don’t stick to the wound bed. They also keep the burn moist, which promotes cell migration and tissue repair. These are available over the counter at most pharmacies.
For very small, superficial burns (think: a brief contact with a hot pan), a transparent film dressing can work. These are thin, flexible, and waterproof while still allowing the skin to breathe. They’re best for burns that aren’t producing any fluid.
What to Do About Blisters
If your burn blisters, your instinct might be to pop it. The right approach depends on the blister’s size.
Small, intact blisters (under about 6 millimeters, roughly the size of a pencil eraser) should be left alone. They act as a natural bandage that protects the wound underneath and helps control pain. They’re unlikely to rupture on their own.
Large, thin-walled blisters are more likely to burst on their own, and uncontrolled rupture increases infection risk. According to guidelines from the British Burn Association, these are best deroofed (the dead skin removed entirely) so the wound underneath can be properly assessed and treated. The same goes for blisters that have already ruptured, since the loose skin becomes non-viable tissue that can harbor bacteria. If you have a large blister or one in an area that limits movement (like on your palm or a finger joint), it’s worth having a healthcare provider handle it rather than trying to manage it yourself.
Managing Pain at Home
Burns hurt, and the pain from a first- or second-degree burn can last several days. Over-the-counter pain relievers like ibuprofen or acetaminophen can help. Ibuprofen has the added benefit of reducing inflammation around the burn.
Keeping the burn moist with petroleum jelly or aloe vera also reduces pain. Dry, exposed burns are significantly more painful than covered, moist ones. Cool compresses can provide temporary relief, but avoid re-cooling the burn for extended periods after the initial 10-minute treatment.
Signs the Burn Needs Medical Attention
Most small first-degree burns and minor second-degree burns heal within one to three weeks with basic home care. But certain burns should be seen by a professional promptly:
- Burns on the face, hands, feet, groin, or over a joint carry higher risks of complications and scarring.
- Burns larger than 3 inches across, even if they look superficial.
- Burns that wrap around an arm, leg, or finger can restrict circulation as swelling develops.
- Any burn that looks white, brown, black, or leathery, which suggests full-thickness damage.
- Signs of infection developing days later: increasing redness spreading beyond the burn edges, swelling, green or yellow discharge, fever, or worsening pain after the first day or two.
Chemical and electrical burns can cause internal damage that isn’t visible on the surface and should always be evaluated professionally, even if the skin looks only mildly affected.
