Myth Busting Monday: Does Butter Soothe a Burn?

Butter doesn’t soothe a burn. It insulates it. Fat is a poor conductor of heat, so spreading it over hot skin holds the heat in the tissue while the damage is still going on underneath.

MYTH	“Butter or margarine soothes a burn.”
FACT	Grease traps heat in the skin, raises the infection risk and makes the burn harder for a clinician to assess. The only thing that belongs on a fresh burn is cool running water, ideally for 20 minutes, started as soon as possible. NHS advice is never to put creams, oils or butter on a burn or scald.

Nobody argues with me about CPR. But mention butter on a burn and somebody in the room goes quiet, because their mum or their nan did it, and correcting it feels like criticising someone they loved.

So let’s deal with that first. The people who taught you this were doing their best in a kitchen that didn’t have a mixer tap and definitely didn’t have a burns unit down the road. They weren’t stupid. They were wrong, and it matters, because a burn treated with grease carries on getting deeper.

Where does the butter myth come from?

It looks like it works for about three seconds. Butter comes out of the fridge cold, and that first moment of relief is enough for the brain to file it under “this helps”. Then the cold goes and what’s left is a layer of fat sitting on damaged skin.

There’s history in it too. Grease was one of the few things in a Victorian kitchen you could spread over a wound to keep the air off, and the habit outlived the reasoning by about a century.

It also keeps bad company. Toothpaste, egg white, flour, aloe off the windowsill, a splash of vinegar. Same instinct every time: put something on it. The instinct is right. The something is wrong.

What does butter actually do to a burn?

Three things, none of them good.

It keeps the heat in. A burn doesn’t stop when the kettle is out of the picture. The tissue stays hot and carries on cooking itself, which is why a burn can look pink and unremarkable at first and considerably worse an hour later. Cooling is how you stop that. A layer of fat over the top works like a tea cosy on the injury.

It invites infection. Burnt skin has lost the barrier that keeps bacteria out. Butter and margarine aren’t sterile. They’re food, sitting at body temperature on an open wound.

It gets in the way of treatment. Grease has to come off before anyone can judge how deep the burn goes, and cleaning it off raw skin hurts. It doesn’t just fail to help. It adds a painful step before real treatment can start.

Margarine, lard, olive oil, Vaseline, dairy of any kind. Same problem, same physics. The label on the tub makes no difference.

What happens under the skin when a burn is cooled with running water, compared with what happens when it’s covered in grease.

What actually belongs on a burn

Cool running water, and nothing else, until it’s properly cooled.

The NHS says 20 minutes under cool running water, or until the pain eases. UK burns services, and the Children’s Burns Trust teach a firm 20 minutes as part of Cool, Call, Cover. Twenty is the number I teach, because it’s what burns specialists ask for and nobody has ever been harmed by cooling a burn properly.

The rest, in order:

• Water on, and keep it cool or lukewarm. Not ice, not iced water, not frozen peas. Ice damages skin that’s already injured and can deepen the burn.
• Get rings, watches and clothing off the area while you’re cooling. Everything swells. Anything stuck to the skin stays exactly where it is.
• Cool the burn, warm the person. Twenty minutes at a cold tap will chill anybody, and small children and older adults lose heat fast. Blanket over the shoulders, keep it clear of the burn.
• Cover it once it’s cooled. Cling film laid loosely over the top, never wrapped around a limb, because the area needs room to swell. A clean plastic bag works for a hand or foot. Not cotton wool; the fibres stick.
• Leave blisters alone. An intact blister is a sterile lid.

If someone has already put butter or cream on it, wash it off gently and cool the burn properly. Late cooling still helps, so don’t write off the water because time has passed.

Twenty minutes is longer than anybody thinks

This is the part that catches people out, and it isn’t the butter.

Ask a group how long they’d hold a burn under the tap and the honest answers land between one and five minutes. Nobody says twenty. What usually happens is the pain eases after a couple of minutes, and everyone takes that as the all clear. It isn’t. The pain easing is the water doing its job.

It’s a staffing problem as much as a clinical one. In a care home, a school kitchen or a salon, somebody is now stood at a sink for a third of an hour and someone else has to cover the floor. If that hasn’t been thought about before it happens, the cooling is what gets cut short.

Which burns need more than a cold tap?

Cooling starts immediately in every case. While that’s happening, someone else gets help if any of this applies:

• Bigger than the casualty’s own hand
• Skin that looks white, brown, leathery or charred, or a burn that’s gone numb rather than painful
• Face, hands, feet, genitals, or right around a limb or across a joint
• Chemical or electrical burns, or any significant burn to a baby, a child, someone pregnant, someone frail or over 60
• Soot around the nose or mouth, a hoarse voice, coughing or any difficulty breathing. That’s an airway burn and an immediate 999 call

For children, the Children’s Burns Trust threshold is simple, and I like it: anything bigger than a 50p coin, get advice.

A burn that has stopped hurting is not a burn that’s improving. Numbness usually means the nerve endings have gone, which makes it deeper, not milder.

Cool, Call, Cover: the first 20 minutes, and the burns that need help on the way.

What changes if it happens at work

Some burns are reportable. Under RIDDOR 2013, a specified injury includes any burn covering more than 10% of the whole body’s total surface area, or causing significant damage to the eyes, respiratory system or other vital organs. That’s a legal duty sitting on top of the first aid, and it catches employers out.

Check what’s actually in your kit. Plenty of workplace kits carry burn gel dressings, and they’re a perfectly good covering once cooling is done. They are not a replacement for 20 minutes of running water, and I’ve seen them used as one. Water first, gel afterwards.

If you run a kitchen, a care home, a nursery, a salon or a workshop, this is a five-minute conversation at a team meeting. Where’s the nearest tap that runs cool? Who covers the floor for 20 minutes? Where’s the cling film?

FAQs

Training that answers this before the kettle does

Burns get dealt with by whoever is standing nearest, which is why the 20-minute rule needs to be in more heads than just the designated first aider’s.

Emergency First Aid at Work (EFAW) is the level most workplaces need, and higher risk settings like kitchens and workshops usually need the three day First Aid at Work qualification. Schools want Emergency First Aid for Schools, and anyone working with young children needs Emergency Paediatric First Aid or the two-day Paediatric and Early Years First Aid for Ofsted compliance.

THE VERDICT: BUSTED

Butter belongs on toast. A fresh burn wants cool running water, and rather more of it than most people are willing to give.
