Tallow Skincare Routine For Eczema – What Nobody Is Telling You

Eczema affects one in eight New Zealand children and one in twelve adults. That’s not a fringe condition. That’s a significant portion of the population waking up with skin that itches, weeps, flares and refuses to settle — often despite doing everything they’ve been told to do. The standard advice is familiar: an emollient cream, a steroid when it flares, a gentle liquid soap. And for infected eczema, diluted bleach baths — a medically endorsed practice that many families find themselves turning to out of desperation.

There is nothing wrong with seeking medical guidance. But there is a conversation that rarely happens in those appointments — about what the skin’s own ecosystem actually needs to heal, and about the growing body of research connecting what happens on the skin to what’s happening inside the body. This is that conversation.

We talk about the skin barrier as though it’s a wall — something fixed that you either have or you don’t. But your skin is far more complex than that. Covering more than two square metres of your body, it hosts over 1.5 trillion microbes across hundreds of species. A living, dynamic ecosystem that plays a vital role in immune function, wound healing and keeping the outside world out.

Eczema is strongly associated with an overgrowth of Staphylococcus aureus — a bacterium that thrives when the skin’s microbial diversity is disrupted. When the ecosystem is out of balance, the barrier becomes compromised, moisture escapes, irritants get in, and inflammation cycles. This is why eczema is so persistent. It’s not just dry skin. It’s a disrupted ecosystem that needs conditions to rebalance — not constant intervention.

Here’s the part nobody talks about. The products sitting in most New Zealand bathrooms — the liquid hand soaps, the body washes, the gentle cleansers — are often working directly against eczema-prone skin. Most liquid soaps and cleansers contain something called sodium lauryl sulfate, or SLS — it’s what makes them foam. The problem is that SLS strips the skin. Not just dirt and bacteria, but the skin’s own protective oils and moisture. Research has shown it measurably increases the rate at which moisture escapes through the skin.

People with eczema already have lower levels of ceramides — the natural fats that hold the skin barrier together and keep moisture in. That makes their skin significantly more vulnerable to this kind of damage. In other words, the soap designed to gently clean their skin is quietly making their barrier worse every single time they use it.

SLS isn’t the only problem hiding in plain sight. Synthetic fragrance is responsible for up to 40% of allergic reactions from personal care products — and products labelled ‘unscented’ may still contain masking fragrances that trigger reactions. Even some products labelled natural, organic or herbal contain common allergens. As the Eczema Association of New Zealand notes — natural does not mean safe.

Parabens, propylene glycol, alcohol-based toners, formaldehyde-releasing preservatives — the list of common skincare ingredients that can aggravate eczema-prone skin is long. And these ingredients aren’t hidden in obscure products. They’re in the ones most heavily marketed to people with sensitive skin. That squeaky-clean feeling after washing? It’s not clean skin. It’s stripped skin. And stripped skin — skin that’s lost its natural oils, its ceramides, its microbial balance — is exactly what Staphylococcus aureus thrives on.

Here’s what rarely comes up in a dermatology appointment. Your skin and your gut are in constant conversation.

It’s called the gut-skin axis — and it simply means that what’s happening in your digestive system shows up on your skin. Research has found that babies with less diverse gut bacteria are significantly more likely to develop eczema. Chronic stress raises cortisol, which weakens the gut lining and increases inflammation throughout the body — affecting both the gut barrier and the skin barrier at the same time.

Researchers now describe this as leaky gut and leaky skin. Two barriers. Both compromised. Both connected.

Stress isn’t just emotional. It has a direct physical impact on the skin. The Eczema Association of New Zealand acknowledges that emotional stress can play a large role in triggering eczema flares — and the reason is straightforward. When we’re stressed, cortisol rises. That disrupts the gut, drives inflammation through the body, and throws off the delicate microbial balance the skin depends on to stay healthy.

This is why eczema is rarely just a skin problem. What you put on your skin matters enormously. But it is one part of a much larger picture. That larger picture doesn’t make topical care less important. It makes choosing the right products more important.

The skincare industry has a problem it doesn’t like to talk about. Not a lack of innovation or research — there is plenty of both. The problem is that the conversation about what eczema-prone skin actually needs has been largely absent from the products designed for it.

Your skin barrier is made of lipids — ceramides, cholesterol, fatty acids. When that barrier is compromised, as it is in eczema-prone skin, it needs ingredients that speak its language. Not synthetics. Not petroleum. Fats that the skin already recognises. Grass-fed tallow shares the same fatty acid profile as human skin sebum — oleic, palmitic and stearic acid. These are the building blocks your barrier is made from. Because of this, it absorbs rather than sits. It works with your barrier rather than coating it.

For eczema-prone skin, the occlusive — the ingredient that seals in moisture — you choose matters more than most people realise. Petroleum-based creams create a physical seal — nothing more. They don’t contribute to barrier repair. They don’t bring anything the skin can use. Tallow does something different — sealing and supporting at the same time. It also brings fat-soluble vitamins A, D, E and K — nutrients that support cell turnover, calm inflammation and protect against oxidative stress. And because a well-made tallow balm contains nothing it doesn’t need to — no water, no emulsifiers, no preservatives — there is very little for sensitive skin to react to. For more on how tallow supports the skin barrier, read my piece on healing your skin barrier naturally.

Botanicals aren’t decoration. For eczema-prone skin they are concentrated plant intelligence — compounds developed over centuries to protect, repair and calm.

Calendula is one of the most studied skin-healing herbs, known for promoting tissue regeneration and reducing inflammation. Chamomile brings calming, anti-inflammatory properties that are well documented for reactive skin. Annatto — the richest known plant source of tocotrienols — offers antioxidant protection significantly more potent than conventional vitamin E, quietly protecting the repair work happening underneath.

St John’s Wort — Hypericum perforatum — has a long history of topical use for wounds, burns and inflammatory skin conditions. Studies suggest its active compound hyperforin has both anti-inflammatory and antibacterial properties, including a potential effect on Staphylococcus aureus — the bacterium most strongly associated with eczema flares. In a clinical study, topical St John’s Wort outperformed placebo at every point over four weeks in the treatment of mild to moderate eczema — and participants found it gentle and comfortable on skin.

What makes this particularly striking is that the same ingredient shown to damage eczema-prone skin — SLS — was used as the irritant in studies testing St John’s Wort’s anti-inflammatory properties. Researchers deliberately irritated skin with SLS to create a measurable inflammatory response, then demonstrated that St John’s Wort reversed that damage. The botanical that may help eczema-prone skin was proven effective against the very ingredient found in most of the products being sold to people with eczema.

These botanicals aren’t in most eczema products. They’re in Fatglow’s — and St John’s Wort will be joining them soon.

A Simple Tallow Skincare Routine for Eczema-Prone Skin

The golden rule for a compromised barrier: fewer products, better ingredients, applied with care.

Cleanse gently – Use a mild, non-stripping cleanser or a tallow-based soap free from SLS, synthetic fragrance and harsh preservatives. Check your labels — the ingredients in your cleanser matter as much as what you apply afterwards.

Apply to damp skin – Immediately after cleansing, before moisture has fully evaporated, your skin is most receptive. Don’t wait. For a deeper look at why this matters, read our guide to healing your skin barrier naturally.

Serum first — if your skin can tolerate it – For skin that isn’t in an active flare, a lightweight botanical serum brings essential fatty acids and antioxidant support before the final step. The Fatglow Red Velvet Botanical Serum — jojoba, olive squalane, rosehip, pomegranate, red velvet oil and grass-fed tallow — was made for this moment. Press a small amount gently into damp skin.

Seal with tallow balm – The Fatglow Roman Chamomile Tallow Balm — with calendula and annatto — brings botanical anti-inflammatory support while the tallow seals everything beneath it. Warm a small amount between your fingertips and press gently into skin. A little is genuinely enough.

Two steps after cleansing. Nothing more needed.

Managing Bacteria Without Destroying Your Skin Microbiome

For infected eczema, bleach baths are sometimes recommended to reduce Staphylococcus aureus — and for actively infected skin, this has medical backing. The Eczema Association of New Zealand provides detailed guidance on this approach for those whose eczema is infected and difficult to control.

But your skin is home to an extraordinary diversity of microbes — and not all bacteria are the enemy. For eczema that isn’t actively infected, protecting that microbial ecosystem may matter as much as reducing harmful bacteria. Gentler bathing options offer a soothing alternative that helps rebalance the skin’s environment without disruption. Colloidal oat baths are a well-regarded option, known for their ability to calm inflammation and relieve itching in eczema-prone skin.

After any bath, pat skin dry gently and apply a tallow balm immediately while skin is still slightly damp. That final occlusive step is what gives your barrier the conditions it needs to begin repairing.

Always consult your health professional about what’s right for your situation.

When Your Skin is in a Flare

Skip the serum. Cleanse gently with a non-stripping tallow soap, apply tallow balm to damp skin, and leave your skin alone. No actives, no treatments, nothing that promises to transform. A barrier in a flare needs calm, not intervention. Given the right support and time it can begin to recover. Resist the urge to reach for more.

If you have been using topical steroid creams long term, read my separate guide on topical steroid withdrawal before making any changes to your routine.
