Severe Nappy Rash Treatment for Stubborn, Angry-Looking Skin

When Ordinary Nappy Rash Balm Has Not Been Enough

ANGRY BITS is our more intensive balm for very red, stubborn nappy skin that needs extra moisturising, protection and barrier support. Rich, concentrated and soft enough to press gently onto sensitive skin without dragging. For intact skin only. If the area is broken, bleeding, weeping, blistered or infected-looking, speak to your pharmacist, health visitor or GP instead of applying a new cosmetic product.

When the Ordinary Balm Is Not Quite Enough

RICHER CARE FOR STUBBORN, INTACT SKIN

When you have changed the nappy, cleaned gently and applied the usual balm, but the bottom is still furious, you need a more intensive next step.

ANGRY BITS combines a rich tallow base with beeswax, zinc oxide, calendula, rosehip, panthenol, chamomile and tamanu oil.

Together, these ingredients moisturise and soften the affected area, calm the look of angry redness and create a protective coating against further dampness and rubbing.

The balm melts between warm fingertips, so you can press on a thin layer without scraping thick paste across skin that has already had quite enough excitement for one nappy change.

Richer barrier care for very unhappy-looking skin, provided the surface remains intact.

Why ANGRY BITS Is More Intensive


ANGRY BITS begins with the same rich tallow-based foundation as BUM + BODY, but it is made for stubborn areas that need a richer balm.

The main ingredient difference is tamanu oil. We include it alongside tallow, calendula, rosehip, panthenol, beeswax and zinc oxide in the targeted ANGRY BITS formula.

ANGRY BITS moisturises and softens irritated-looking skin, calms the appearance of angry redness, shields the area from further moisture and rubbing, supports the skin barrier while it repairs, and melts on gently and stays in place without becoming chalky.

It is concentrated, so more is not better. A thin layer is enough to cover the affected area and give it proper protection.

ANGRY BITS is our more intensive formula. It is not a medicine and does not treat fungal or bacterial infection.

WHAT’S INSIDE

Ingredients Chosen for Stubborn, Angry-Looking Skin


ANGRY BITS uses grass-fed beef tallow as its rich, moisturising base. Beeswax and zinc oxide help the balm stay in place and shield the skin from the constant moisture and rubbing inside a nappy.

Calendula, rosehip and panthenol moisturise and care for the irritated skin underneath. Chamomile gives the balm its light botanical scent, while tamanu oil is the main ingredient difference between ANGRY BITS and BUM + BODY.

Each ingredient has a clear job. Grass-fed beef tallow creates a deeply moisturising base, while beeswax helps the balm stay in place and zinc oxide supports protection from moisture. Calendula helps soothe and calm the look of irritation, rosehip oil nourishes and softens, and panthenol moisturises and conditions the skin. Chamomile adds further soothing support, while tamanu oil gives ANGRY BITS its more targeted, intensive formula.

Tamanu caution: Follow the allergy and sensitivity information on the product label. Patch test before first use and do not apply ANGRY BITS if there is a known sensitivity to tamanu.

Matylda Baby founders behind a gentle nappy rash balm made by mums for babies

MADE BY MUMS

Why We Made ANGRY BITS

Matylda Baby began because my daughter Matylda’s skin was red, sore and getting nowhere with the growing collection of products beside the changing mat.

Emma, my best friend and a natural cosmetics expert, and I first created BUM + BODY as our everyday balm. But some stubborn, angry-looking patches needed more.

That is why we developed ANGRY BITS: a richer formula with tamanu oil for the moments when the ordinary balm is doing its best, but the skin still looks furious.

It is not intended to replace medical care or go onto broken skin. It is our more intensive option for intact skin that needs a richer, targeted balm.


No Dragging. No Chalky Paste.

When a baby’s bottom looks extremely red, the last thing you want is a cream that needs rubbing, scraping or the upper-body strength of a small builder.

ANGRY BITS is firm in the tin, then melts quickly between warm fingertips into a silky, oil-like texture.

Press or smooth a very thin layer over clean, dry, intact skin. It leaves a rich protective coating without feeling gritty or requiring a minor wrestling match at every change.

A little truly goes a long way.

Frequently Asked Questions

When Is ANGRY BITS the Right Matylda Balm?

ANGRY BITS is our more intensive formula for stubborn, very angry-looking areas that need extra moisturising and protection.

It may be the better Matylda option when:

  • The redness is much more pronounced than usual
  • The same area keeps returning
  • BUM + BODY has not felt sufficient
  • The area has not settled with ordinary care
  • The surface remains closed and intact

It is not intended for skin that is no longer intact.

What Is the Difference Between BUM + BODY and ANGRY BITS?

BUM + BODY is our everyday formula for ordinary redness, soreness and regular family use. It is also the tamanu-free option.

ANGRY BITS is richer and more intensive. It contains tamanu oil and is made for targeted use on stubborn, angry-looking areas of intact skin.

Choose according to what the skin looks like now: BUM + BODY for ordinary irritation, or ANGRY BITS when the area is considerably angrier and has not settled with ordinary care.

Can I Use ANGRY BITS on Raw-Looking or Broken Skin?

People use “raw-looking” to mean different things.

If the skin looks extremely red and angry but the surface remains intact, ANGRY BITS may be suitable.

Do not apply it to open, broken, bleeding, weeping or blistered skin. Ask your pharmacist, health visitor or GP for advice instead.

What Should I Do If the Rash Is Worsening or Not Improving?

Speak to your pharmacist, health visitor or GP if the rash persists, worsens or spreads despite frequent changes and gentle care.

Seek advice sooner if your baby appears unwell or unusually uncomfortable.

The when to worry about nappy rash guide explains the warning signs and what to do next.

Could the Rash Be Fungal or Infected?

Different rashes can look surprisingly similar. Thrush, bacterial infection, contact irritation and ordinary nappy rash can overlap, so it is not always possible to identify the cause from appearance alone.

ANGRY BITS is not an antifungal or antibiotic treatment. If you suspect infection, ask a healthcare professional for advice.

Our complete nappy rash guide explains common causes, what different rashes can look like and when to ask for professional advice.

How Much ANGRY BITS Should I Apply?

Use a very small amount on clean, dry, intact skin.

Warm it between your fingertips, then press or smooth on a thin layer without rubbing. The skin should have a light coating, but it does not need to disappear beneath the balm.

More product does not mean faster results.

Can I Apply ANGRY BITS at Every Nappy Change?

ANGRY BITS can be reapplied as directed while the stubborn area needs extra care.

At each change, remove anything soiled gently, clean the skin, pat it completely dry and apply another thin layer where needed.

If the skin is worsening or is no longer intact, stop using the balm and seek advice.

Can I Use ANGRY BITS Overnight?

Yes, on clean, dry, intact skin.

Apply a thin layer before the overnight nappy. Change the nappy sooner if it becomes heavily soiled, particularly during diarrhoea or frequent loose stools.

If the skin has worsened or is no longer intact at the next change, stop using the balm and seek advice.

What Is Tamanu Oil, and Why Is It in ANGRY BITS?

Tamanu oil is the main ingredient difference between ANGRY BITS and BUM + BODY.

We include it in ANGRY BITS for stubborn areas that have not settled with ordinary care. It works as part of the complete formula alongside tallow, calendula, rosehip, panthenol, zinc oxide and beeswax.

Follow the allergy and sensitivity guidance on the product label and patch test before use.

Can ANGRY BITS Be Used From Birth?

ANGRY BITS can be used from birth as directed on intact skin.

Patch test a very small area first, particularly if your baby’s skin is highly reactive. Follow the product’s allergy and sensitivity information because the formula contains tamanu oil.

Avoid the eyes and mouth.

What Else Can I Do Alongside Using the Balm?

Keep the routine simple:

  • Change wet or dirty nappies promptly
  • Clean gently rather than scrubbing
  • Pat the area completely dry
  • Avoid introducing several new products at once
  • Watch for worsening or spreading symptoms

Do not allow home care to delay professional advice if the rash is not improving or your baby seems unwell.

What Should I Use After the Skin Settles?

Once the angry-looking area has settled, ANGRY BITS may no longer be necessary.

Use BUM + BODY for ordinary nappy-area care and mild redness. When the skin looks comfortable and you mainly want protection against moisture and rubbing, explore our everyday baby barrier cream.
