We expect more from a nappy cream than a thick coating. BUM + BODY sinks into skin to help repair and restore its natural barrier, while protecting little bums from surprise angry poos. Our secret? There isn’t one. We haven’t cut corners: skin-loving ingredients in generous concentrations, no fillers, and a formula we made for our own babies.
The result is an intelligently formulated baby balm that is easy to use and actually works.
“I love this product. It was recommended to me, and I don’t regret buying it at all. My baby had a nappy rash, and it cleared up in no time, so it’s definitely effective. Not to mention, the ingredients are very well put together, everything has a purpose, with no unnecessary additives.”
When skin is visibly irritated, protection alone just isn’t enough.
A good baby nappy rash cream should soothe sore skin, ease the sting and help the skin recover, making things peachy again.
Even if you’re not battling an angry rash and just want everyday protection, look for a formula with ingredients as close as possible to those naturally found in your baby’s skin. Give petrochemicals and artificial fragrances a wide berth. And if you use reusable nappies, choose a formula that absorbs quickly without leaving a stubborn residue to wash out.
Shameless plug: BUM + BODY ticks all those boxes. It is fully safety-assessed and suitable from birth, with every ingredient listed so you know exactly what goes on your baby’s skin. No-brainer, right? We thought so too, but we couldn’t find a balm that did all that. So we made it.

WHY WE CREATED MATYLDA
Matylda Baby began when Hana couldn’t find a cream that helped her daughter’s red, sore skin. She teamed up with her best friend Emma, a natural skincare expert, to create BUM + BODY: a nourishing balm that uses only natural, pure ingredients and that finally helped Matylda’s skin to recover.
Today, we bring that same loving care to other families, with one simple promise: we only make products we’d confidently use on our own babies.
When a little bottom is already red and sore, the last thing it needs is a thick, grainy nappy cream. Firm in the tin, BUM + BODY Balm melts almost immediately between your fingertips into a smooth, oil-like texture. It glides gently over sore skin without dragging. Start with a small amount and add more only where needed.
A little really does go a long way.
step 1
Clean and Dry
Clean the nappy area gently and pat it dry. Avoid unnecessary rubbing.
step 2
Warm the Balm
Scoop out a small amount and warm it between clean fingertips. It will soften almost immediately.
step 3
Apply a Thin Layer
Press or smooth the balm gently over the irritated area.
Frequently Asked Questions
What Is Nappy Rash Cream?
Nappy rash cream is used when the skin under the nappy is already red, sore-looking or irritated.
It helps protect the area from further contact with moisture, wee, poo and rubbing while keeping the skin moisturised and supported as it repairs.
BUM + BODY has a soft balm texture rather than a thick white paste. It melts between warm fingertips and can be pressed gently onto the skin without unnecessary dragging.
What Makes BUM + BODY Suitable for Irritated Nappy Skin?
BUM + BODY combines several types of support in one formula.
Tallow and rosehip oil moisturise and soften. Beeswax and zinc oxide help shield the skin from further moisture and rubbing. Calendula, panthenol and chamomile help care for skin that looks red or feels uncomfortable.
The balm is waterless, concentrated and designed to be used in a thin layer. It contains no petroleum or synthetic fragrance and is safety assessed and compliant with UK Cosmetic Product Regulations.
What Is the Difference Between Nappy Rash Cream and Baby Barrier Cream?
Use barrier cream before the skin becomes sore or when it tends to redden easily.
Once the bottom is already red and uncomfortable, choose care made to moisturise, soothe and protect it while it settles.
Some balms can offer both kinds of protection, but what the skin needs at that moment should guide how you use them.
How Much Nappy Rash Balm Should I Apply?
Apply a thin, even layer over clean, dry skin.
Begin with roughly enough balm to coat the tip of one clean finger for a small area. Warm it between your fingertips before gently pressing or smoothing it onto the skin.
The skin should have a light coating, but it does not need to disappear beneath the balm. Using more does not automatically make it work faster.
Should I Use BUM + BODY at Every Nappy Change?
You can reapply BUM + BODY as needed while the skin is irritated.
At each change, remove any soiled balm gently, clean the area and pat it dry. Apply a fresh thin layer where the skin still needs protection.
Once the skin looks comfortable again, you may choose to use it less often or switch to routine preventative care during longer naps, overnight or other times when irritation is more likely.
Should I Remove All the Balm at Every Change?
No. You do not need to scrub away every trace of clean balm.
Remove anything soiled, clean the skin gently and leave any clean coating that is still in place. Add a small amount of fresh balm where necessary.
Hard rubbing creates more friction and can make the skin even less impressed with the entire nappy-changing arrangement.
Can I Use BUM + BODY Overnight?
Yes. Apply a thin layer to clean, dry skin before the overnight nappy.
The balm is rich and waterless, so it stays in place and helps shield the skin during a longer stretch in the nappy.
Change the nappy sooner if it becomes heavily soiled, particularly during diarrhoea or frequent loose stools.
Can BUM + BODY Balm Be Used From Birth?
BUM + BODY is made with grass-fed beef tallow, beeswax, zinc oxide, calendula, rosehip oil, panthenol and chamomile. Each ingredient has a clear purpose, and the finished balm has been properly safety assessed and is compliant with UK cosmetic regulations.
There is no petroleum, mineral oil or synthetic fragrance in the formula.
For us, “natural” only means something when the ingredients have been chosen to do a proper job.
What Makes This a Natural Nappy Rash Cream?
In some cases, yes. If a cream is too thick, heavily fragranced or not suited to sensitive skin, it can feel uncomfortable or trap irritation.
Some products focus only on creating a barrier, which may not help if the skin is already inflamed.
If the rash seems to worsen, it can be worth switching to a simpler, more balanced formula that supports the skin rather than overwhelming it.
Gentle, well-formulated balms are often better tolerated by reactive skin.
Does BUM + BODY Contain Zinc Oxide?
Yes. We use zinc oxide alongside tallow, beeswax, calendula, rosehip and panthenol.
It helps create separation between the skin and the damp, irritating environment inside a nappy. We use it as part of the wider formula rather than relying on a dry, zinc-heavy paste alone.
What Is the Difference Between BUM + BODY and ANGRY BITS?
BUM + BODY is our everyday formula for visible redness, soreness and regular family use.
ANGRY BITS is our more intensive balm for stubborn, angry-looking areas of closed skin when BUM + BODY does not feel like quite enough. It contains tamanu oil and should not be used where there is a known sensitivity or allergy to tamanu or related nuts.
If the rash is stubborn or very angry-looking but the skin remains closed, read our guidance onsevere or persistent nappy rash.
What Should I Do If the Rash Looks Severe or Is Not Improving?
Speak to your pharmacist, health visitor or GP if the skin is broken, bleeding, weeping, blistered, spreading, infected-looking or unusually painful, or if your baby seems unwell.
You should also seek advice if the rash is not improving despite regular changes and appropriate care.
Our guide towhen to worry about nappy rash explains the warning signs and when professional advice is the right next step.
