Can you put Vaseline or a balm on a burn?

Not on a fresh burn. Cool it under running water for 20 minutes first. Once a minor burn is cooled and healing, petroleum jelly or an emollient ointment is fine.

Not on a fresh burn, but yes once it has cooled and is healing. First hold the burn under cool running water for 20 minutes, then lay cling film over it, and put no cream, oil, butter or balm on it at this stage. The NHS, the British Red Cross and St John Ambulance all say so. Later, as a small burn heals, a greasy product does have a place. The American Academy of Dermatology (AAD) says to put petroleum jelly on a minor burn two to three times a day, and the NHS says to use an emollient ointment if the skin gets itchy and dry as it heals. That is the same idea at two points in time, not a real disagreement.

• Cool: 20 minutes under running water
• Start within 3 hours (NHS)
• Fresh burn: no creams, oils or butter
• Minor burn, once cooled: petroleum jelly 2 to 3 times a day (AAD)
• Itchy and dry while healing: emollient ointment (NHS)

What counts as a burn, and what "minor" means

A burn is skin damaged by heat, and the NHS splits it in two. A burn comes from dry heat, such as fire or a hot iron, and a scald comes from hot liquids or steam. The British Red Cross puts it the same way and adds the line that matters most here: "You can treat burns and scalds in the same way." So everything below applies to both.

The AAD's petroleum jelly advice is for one kind of burn only, the first-degree burn. Its page defines that as a burn that involves "only the top layer of the skin", where the skin is red and painful and there may be mild swelling. Its examples include touching a hot stove or hair straighteners. The AAD calls second-degree and third-degree burns "more severe", and its page on minor burns does not cover them.

The NHS does not use degrees. It says small burns and scalds "can often be treated at home", while large or deep ones may need hospital. "Minor" in this article means small, not deep, and not on a part of the body that needs a doctor (the list comes further down).

Two product words matter as well. Vaseline is a brand of petroleum jelly, a soft, greasy blend of oils and waxes refined from crude oil and called white soft paraffin in the UK, as petrolatum and mineral oil explains. An emollient is any product that softens skin by laying down oil or fat. An ointment is a greasy product with no water in it, thick enough to sit on the skin as a layer. Petroleum jelly is both. A balm, the subject of this site, is much the same kind of thing, an oil and wax blend with no water, and the fine differences are in balm vs salve vs ointment vs cream.

Why nothing greasy goes on a fresh burn

All four bodies say no to creams and oils on a burn that has just happened, and between them they give three reasons.

Oil holds heat in. The British Red Cross answers the butter question head on: "Butter, cream or toothpaste will not cool the area. Butter and cream contain oils. Oils retain heat, which is the opposite of what you're trying to do." Petroleum jelly and balms are oils and waxes too, so the same logic applies to them.

It may have to come off again. The Red Cross adds a second reason: "If you put anything on top of a burn and it later needs to be removed in hospital, it may cause further pain and damage." At home you cannot always tell how deep a burn is, so you cannot be sure it will not end up in hospital.

Infection. The NHS simply says "do not put any creams, oils or butter on burns or scalds". St John Ambulance says not to use ice, creams or gels, because "they may cause damage and increase the risk of infection". The AAD says not to put ointments, toothpaste or butter on a burn, "as these may cause an infection", and not to use topical antibiotics.

Cooling products fare no better. The Red Cross says toothpaste often contains menthol, which "may give a superficial feeling of cooling, but does not effectively help a burn". Menthol is in many cooling lip balms and rubs as well. It makes nerves report cold, as menthol and camphor safety limits explains, which is not the same as taking heat out. None of the four bodies suggests a scented, herbal or cooling balm at any stage, so this page does not either.

Step by step: first aid for a burn

The four bodies agree on almost every step. Here is the order, with who says what.

1. Cool it under running water, now. The NHS says to hold the burn under cool running water for 20 minutes, "as soon as possible, within 3 hours of it happening". The Red Cross says cold running water "for at least 20 minutes", and St John Ambulance says cool running water "for at least 20 minutes or until the pain feels better". The AAD says cool tap water or cold, wet compresses "for about 10 minutes or until the pain subsides". The next section explains why 20 is the figure to use.
2. No tap? Use what you have. The NHS suggests cool bottled water or a wet towel, St John Ambulance cold milk or canned drinks, and the Red Cross milk, soft drinks or beer.
3. Take off rings, watches and clothing near the burn. St John Ambulance says to do it "before the area begins to swell". The NHS, the Red Cross and St John Ambulance all say to leave anything that is stuck to the burn.
4. Cover it loosely with cling film once it has cooled. The NHS says to lay cling film over it and "do not wrap the cling film around it". St John Ambulance says to lay it lengthways, because "the area needs space to swell". On a hand or foot, the Red Cross and St John Ambulance both say a clean plastic bag will do. The Red Cross says cling film "won't stick to the burn".
5. No plasters. The NHS says not to use plasters or sticky dressings, and the Red Cross says adhesive bandages "stick to the skin and can cause further damage".
6. Leave blisters alone. The NHS, the AAD and St John Ambulance all say not to burst them, and the AAD says to let them heal while keeping the area covered.
7. Take a painkiller if you need one. The NHS names paracetamol or ibuprofen, and the AAD names acetaminophen (the US name for paracetamol) or ibuprofen.

There is no balm, Vaseline, butter or ice anywhere on that list.

Ten minutes or twenty: which to follow

Use 20 minutes. Three of the four bodies say it, and the fourth does not rule it out.

Search results mix UK and US pages, so people see both numbers side by side and assume one must be wrong. The AAD's figure sits on a page about first-degree burns only, and its wording is loose: "about" 10 minutes, "or until the pain subsides". Twenty minutes meets every source at once, while ten meets only one. The Red Cross also gives the reason to lean longer: "The sooner and longer a burn is cooled with cold running water, the less the impact of the injury."

Two limits come with the longer time. The water should be cool or cold, not iced: St John Ambulance says not to use ice, and the Red Cross answers its own ice question with "use cold water". And cool the burn, not the whole person: the Red Cross warns that a whole body cold shower or bath "could induce hypothermia".

When a greasy product is fine: the AAD route and the NHS route

This is where the two bodies seem to clash, since the NHS says no creams or oils and the AAD says petroleum jelly. Read each page in full and the clash mostly goes away.

The AAD route. The AAD's steps for a first-degree burn run in a fixed order. Step one is cooling. Step two is "Apply petroleum jelly two to three times daily." Step three is to cover the burn with a nonstick, sterile bandage. So the petroleum jelly comes after cooling, on a burn that only involves the top layer of skin. The page does not say why it picks petroleum jelly.

The same step two also says not to apply ointments, toothpaste or butter. Petroleum jelly is an ointment, so on its face that reads as a contradiction, and the page does not explain how the two lines fit. Our reading is the plain one: petroleum jelly is the one product the AAD recommends, and other ointments, antibiotic ones included, are what it rules out.

The NHS route. The NHS page has a short list of things to do "while burns and scalds heal". One of them is to "use an emollient ointment on the affected area if it becomes itchy and dry as it heals", and it adds that "you can ask a pharmacist for advice about what to use". So the NHS also has a place for a greasy product. It just waits for a sign, itchy and dry skin, and leaves the choice of product to a pharmacist.

So the answer to "Vaseline on a burn?" depends on when you ask. Both bodies say cool first, rule out butter and keep blisters intact, and neither puts anything greasy on a burn that is still hot. After first aid, on a small, minor burn, both routes are mainstream advice, so follow whichever one your own doctor or pharmacist works to.

What about a balm instead of Vaseline?

None of the four bodies names a lip balm, a salve or a homemade balm, so this page does not either. Most balms carry extras that plain petroleum jelly does not, such as beeswax, plant butters, essential oils, fragrance, menthol or camphor. None of the bodies recommends any of those on a burn, and the only one any of them mentions is menthol, which the Red Cross says gives a feeling of cooling without helping. If you follow the AAD route, use plain petroleum jelly. If you follow the NHS route, ask a pharmacist which emollient ointment to use. The fear that petroleum jelly itself is harmful on skin is weighed in is petroleum jelly bad for you, and how it compares with plant balms is in natural vs petroleum.

For makers, the label matters too. A balm sold "for burns" makes a medical claim, which takes it out of cosmetics law in the UK and EU and puts it under a drug monograph in the US. Cosmetic vs drug claims sets out the line, and the calendula salve page lists "for burns" among the words a cosmetic cannot use. Sunburn is no different, as the after sun balm formula explains for "soothes sunburn".

Hot wax burns in the workshop

Balm making means hot wax and oil, and a splash on the hand is the most likely injury at the bench. On this site's own figures, a balm melt runs at 70 to 80 C and tubes are poured at 65 to 72 C, as pour temperatures sets out. Molten wax is a hot liquid, so by the NHS's own split a wax splash is a scald, and the Red Cross says burns and scalds are treated the same way. The steps above apply as they stand.

Wax differs from a splash of tea in two ways. It does not run off: melting methods notes that molten fat clings to skin, and the how to make lip balm method says wax and oil at 80 C stick to skin and keep burning after contact. It also sets as it cools, so you can end up with a hard crust over the burn.

None of the four bodies mentions wax by name, but their rule for anything stuck to a burn is the one that fits. The NHS says "do not remove anything that is stuck to the affected area", and the Red Cross says not to remove anything stuck to the burn "as it may cause more damage". So cool the area, wax and all, and do not peel or pick the set wax off. Wax that lifts away with no pulling can go. Wax that is stuck stays, for a doctor or nurse to deal with.

A few workshop habits make the first minute easier:

• Keep the route to the tap clear. You want running water a few steps from the hob, with nothing to move first. Workshop setup covers bench layout.
• Keep the tap water away from the melt. The equipment page warns never to let water splash into hot oil, because it spatters, so cool the burn at a sink that is not next to the pot.
• Keep cling film in the workshop. It is the cover all three UK bodies name, and a clean plastic food bag also works for a hand.

A worked case: wax on the back of the hand

Take a maker pouring lip balm tubes at about 70 C. Suppose the jug tips and a splash the size of a coin lands on the back of their left hand, next to a ring. Nobody tested this exact case. What follows is the four bodies' advice, walked through one small scald.

1. The first seconds. The maker sets the jug down and moves to the sink, away from the pot, switching off the hob only if it is within easy reach.
2. The first minute. The hand goes under cool running water, and while it runs they slide the ring off before any swelling. The splash has set into a thin crust of wax. Part of it floats away by itself, but one patch stays stuck to the skin, so they leave it there.
3. Minute ten. The pain eases. Under the AAD's "about 10 minutes" they could stop here, but under the NHS, the Red Cross and St John Ambulance they keep the water running.
4. Minute twenty. They turn off the tap and slip the hand into a clean plastic food bag, or lay cling film over it loosely. They take paracetamol for the pain.
5. The check. The patch is small and on the hand, not on the face, genitals or bottom, and it did not come from a chemical or electricity. The skin is red and sore but not blistered, which fits the AAD's picture of a first-degree burn. If any of that were in doubt, the next step would be NHS 111, which the NHS says to use if you are not sure what to do.
6. The days after. On the AAD route, they put petroleum jelly on two to three times a day and cover it with a nonstick sterile bandage. On the NHS route, they leave it covered and put nothing on until the healing skin turns itchy and dry, then ask a pharmacist for an emollient ointment. Either way, if a blister forms, it stays intact.
7. Two weeks on. The NHS says small burns and scalds can take around 2 weeks to heal. Once the skin has healed, the AAD says to protect it from the sun with shade, clothing, or a broad-spectrum, water-resistant sunscreen of SPF 30 or higher, because redness from a burn sometimes lasts for weeks, especially on darker skin.

The jar of balm on the bench stays shut throughout.

When to get help instead

In the UK, the NHS says to call 999 or go to A&E if a burn or scald:

• is very large or deep;
• is on the face, genitals or bottom;
• was caused by an acid or chemical, or by electricity.

The NHS adds that you should not drive yourself to A&E: ask someone to drive you, or call 999 for an ambulance. If you are not sure what to do, get help from NHS 111, and call 111 for advice about a child under 5.

The Red Cross goes further for children and says always seek medical advice for a baby or child who has been burned. Its reason is that, depending on the child's age and the size, depth and place of the burn, "even small burns can be potentially life-threatening to a baby or child". Cool their burn for at least 20 minutes first, and if you call 999, keep cooling until the ambulance arrives.

In the US, the AAD says to go to an emergency room straight away if a first-degree burn is very large, if the person burned is an infant or an elderly person, or if you think the burn is more severe. St John Ambulance ends its steps with "Seek medical advice". The NHS covers acid and chemical burns on a separate page, and this one does not.

The four bodies side by side

The four agree on cooling first, no grease in first aid and leaving blisters alone. They differ on cooling time and cover.

What this answer does not cover

This page answers one question, whether petroleum jelly or a balm goes on a burn and when, and makes no claim the four bodies do not make. It is not a guide to judging how deep a burn is. A burn you are unsure about, a burn on a child, or one that is large, deep, chemical or electrical needs NHS 111, A&E or your own doctor, not a product. The AAD's petroleum jelly advice is for first-degree burns only, so do not stretch it to deeper ones. The worked case is a walkthrough of published advice, not a report of a real injury, and no source here compares healing with and without petroleum jelly. None of the four pages covers burns inside the mouth.

One fire point sits outside first aid: dressings that soak up petroleum jelly catch fire more easily, as lip balm and Vaseline with home oxygen explains.
