Moisturising for Eczema: Why It's Essential
If you have eczema, you've almost certainly been told to moisturise more. It's the most consistent piece of advice you'll get — from GPs, dermatologists, and anyone who's read anything about the condition.
But "moisturise more" is a bit like telling someone to "eat better." True, broadly helpful, and not nearly specific enough to actually change anything.
What type of moisturiser? How often? When exactly? And why does your skin still feel dry and reactive even when you're applying something every day?
Why eczema skin needs moisturiser
To understand why moisturising matters so much, it helps to understand what's happening to your skin.
Eczema is strongly associated with a compromised skin barrier — the outermost layer of skin that's supposed to keep moisture in and irritants out. In people with eczema, this barrier doesn't function as it should. It loses water more rapidly than healthy skin (a process called transepidermal water loss), and it's more easily penetrated by allergens, bacteria, and environmental irritants.
This is why eczema skin becomes dry, itchy, and inflamed — it's not just a surface problem. The barrier is structurally impaired, often due to a combination of genetic factors (particularly variations in the gene that produces filaggrin, a protein essential for barrier integrity) and environmental triggers.
Moisturisers — or emollients, as they're often called in a clinical context — can't fix the underlying cause. But they do two things that are genuinely helpful: they reduce water loss from the skin's surface, and they help repair and maintain the protective layer that eczema disrupts. Used consistently, they reduce dryness, itching, and the frequency of flare-ups. They also reduce the amount of topical steroid needed during flare-ups, which is a meaningful benefit for anyone trying to minimise steroid use over time.
How moisturisers actually help eczema
Moisturisers (also called emollients) work by:
forming a protective layer on the skin
trapping moisture inside
reducing water loss
This helps restore the skin barrier and protect against irritation.
Do moisturisers actually improve eczema?
Yes—but with realistic expectations.
Research shows:
moisturisers can reduce eczema severity
help prevent flare-ups
reduce the need for steroid creams
They are considered a core part of eczema treatment.
The difference between lotions, creams, and ointments
Not all moisturisers are equally effective for eczema, and the format matters more than most people realise.
Lotions are the lightest option — they contain a high proportion of water, which makes them easy to apply and fast-absorbing. They're pleasant to use but offer the least lasting hydration. For eczema-prone skin, particularly in drier conditions, lotions often aren't enough on their own.
Creams sit in the middle. They're thicker than lotions, provide better hydration, and are generally well-tolerated for everyday use. Most people find a good cream easier to apply consistently than an ointment — which matters, because consistency is what actually makes a difference.
Ointments are the most occlusive option. They're thick, greasy, and form a strong protective layer on the skin that significantly slows water loss. For very dry or severely affected skin, ointments are often the most effective choice — though many people find them impractical during the day. They're particularly useful at night, when you don't need to worry about how they feel on clothing or skin contact.
As a general rule: the drier and more affected your skin, the thicker the product you need. A light lotion that feels pleasant on normal skin won't do much for skin that's cracked, inflamed, or chronically dry.
What to look for — and what to avoid
The ingredients in your moisturiser matter, but not in the way that most beauty marketing would suggest.
Helpful ingredients for eczema-prone skin:
Ceramides — lipids that naturally occur in the skin barrier. Ceramide-containing moisturisers can help restore barrier function, particularly in people whose eczema is linked to impaired barrier lipid composition.
Glycerin — a humectant that draws moisture from the air into the skin. Effective and well-tolerated.
Petroleum jelly (petrolatum) — one of the most evidence-backed occlusive ingredients. Cheap, effective, and virtually non-allergenic. Vaseline is the most recognisable form.
Colloidal oatmeal — has anti-inflammatory and barrier-supportive properties. Well-suited to reactive and sensitive skin.
Shea butter and natural oils — can be helpful for some people, though responses vary.
Ingredients to avoid:
Fragrance — one of the most common contact allergens in skincare. Even "natural" fragrances can trigger irritation.
Alcohol (denat. or isopropyl) — drying and irritating for compromised skin.
Preservatives such as methylisothiazolinone (MI) — a known sensitiser associated with allergic contact dermatitis.
Strong essential oils — lavender, tea tree, peppermint, and others are frequently reactive on eczema-prone skin despite their natural origin.
The best moisturiser for eczema is usually one with a short, simple ingredient list — not one with an impressive array of actives and botanicals.
Products worth considering
Aveeno Dermexa Daily Emollient Cream
Contains colloidal oatmeal, which has anti-inflammatory properties that make it well-suited to reactive skin. Absorbs well and is comfortable for daytime use.
Cetraben Body Cream
A simple, effective emollient specifically designed for dry, sensitive, and eczema-prone skin. Light enough for daily use, and available on prescription in the UK.
QV Gentle Wash
A soap-free, fragrance-free wash designed for sensitive and eczema-prone skin. Worth including here because what you wash with matters as much as what you apply afterwards.
How often to moisturise — and when
Frequency and timing are just as important as what you're using.
At least twice a day is the minimum for eczema-prone skin. During flare-ups, or in colder, drier conditions, more frequent application — up to four or five times daily — is often necessary.
The most important moment to moisturise is immediately after bathing or showering, while the skin is still slightly damp. Warm water temporarily softens the skin and allows emollients to penetrate more effectively, but it also increases transepidermal water loss as the water evaporates. Applying moisturiser within two to three minutes of patting the skin dry traps that hydration before it escapes.
Before bed is the second most important window. Overnight is when the skin does most of its repair work, and a thicker emollient or ointment applied in the evening can support that process significantly. Many people find that using a lighter cream during the day and a more occlusive product at night is the most practical combination.
During the day, keeping a small pot or tube accessible — at your desk, in your bag, in your car — makes it easier to reapply to dry or irritated areas as needed. The barrier benefit of emollients is cumulative rather than lasting, so regular top-ups throughout the day genuinely help
Common moisturising mistakes
Not using enough
Most people use far less than is needed. For an adult applying emollient to the full body, the general clinical guidance is around 500g per week — significantly more than most people use.
Only moisturising during flare-ups
Eczema needs daily maintenance. Stopping as soon as symptoms improve is one of the most reliable ways to trigger another flare-up.
Using fragranced products
This includes many mainstream body lotions and some "natural" products marketed to sensitive skin. Check ingredient lists carefully.
Not patting skin dry before applying
Rubbing with a towel can cause friction and irritation. Pat gently, and apply immediately while the skin still has some moisture.
Skipping after showers
This is when skin loses the most moisture. Waiting more than a few minutes after getting out of the shower significantly reduces how much hydration is locked in.
Small mistakes can make eczema worse over time.
A practical routine to start with
If you're building or refining your approach to eczema skincare, here's what a solid basic routine looks like:
Morning: Apply a fragrance-free cream or lotion after washing. Reapply to any dry areas throughout the day as needed.
Evening (after bathing): Pat skin dry and apply emollient within 2–3 minutes. Consider a thicker cream or ointment on particularly dry or affected areas. If prescribed, apply any topical treatments before the emollient.
Daily supplement: Take 2 tablets of the Skin Support Formula with food to support skin function from within.
The goal is to make this routine automatic rather than reactive — moisturising every day regardless of how your skin looks, not just when symptoms appear.
Why moisturising alone isn’t enough
For many people with persistent eczema, consistent moisturising makes a real difference — but it doesn't fully resolve the condition. This is because eczema isn't only a surface issue.
The chronic inflammation, immune system dysregulation, and nutritional factors that contribute to eczema aren't addressed by topical skincare alone. This is why symptoms often return, even for people with well-established routines. The barrier is being patched from the outside, but the internal environment that affects how the skin functions isn't being addressed.
This is the gap that internal nutritional support is designed to fill. Nutrients like zinc, vitamin D, vitamin C, biotin, and magnesium each play documented roles in skin barrier integrity, immune function, and cellular repair — the same systems that eczema disrupts. Ensuring your body has adequate levels of these nutrients provides the raw materials the skin needs to maintain and regenerate its barrier from within.
Drought's Skin Support Formulacontains 14 nutrients selected specifically for their role in skin health — designed to be taken alongside your existing skincare routine, not as a replacement for it. It's manufactured in the UK, suitable for vegetarians, and formulated for consistent daily use over time.
For people whose eczema persists despite good topical care, this kind of internal support is often the missing piece.
FAQs: Moisturising and eczema
Can moisturising cure eczema?
No. Eczema is a chronic condition influenced by genetics, immune function, and environmental factors. Moisturising is one of the most effective ways to manage symptoms and reduce flare-up frequency, but it doesn't address the underlying causes.
How often should I moisturise?
2–4 times daily, or more if needed.
What type of moisturiser is best?
Ointments are often most effective for very dry skin.
What is the best moisturiser for eczema in the UK?
There isn't a single answer — individual responses vary. Products containing ceramides (like CeraVe), colloidal oatmeal (like Aveeno Dermexa), or simple occlusive ingredients (like Cetraben or petroleum-based ointments) are consistently well-regarded. Fragrance-free is non-negotiable.
Should I moisturise even when eczema is clear?
Yes — this helps prevent flare-ups.
Can I get emollients on prescription?
Yes. Several emollients — including Cetraben, Diprobase, and Doublebase — are available on NHS prescription. If you're spending significantly on over-the-counter products, it's worth discussing this with your GP.
Should I moisturise eczema during a flare-up?
Yes — and more frequently than usual. During a flare, the skin barrier is even more compromised than normal, so consistent emollient use is particularly important. If you're using prescribed topical steroids, apply these first and then apply emollient on top.
Is Vaseline good for eczema?
Yes. Petroleum jelly is one of the most evidence-backed occlusive ingredients for dry and eczema-prone skin. It's non-allergenic, effective, and inexpensive. It's particularly useful as a nighttime treatment or on very dry, cracked areas.
Why does my skin still feel dry even with moisturiser?
This could be down to the type of moisturiser (a lotion may not be effective enough for very dry skin), the frequency of application, the timing relative to bathing, or the fact that eczema's internal drivers aren't being addressed by topical care alone.
Summary
Consistent emollient use is the most impactful single surface intervention for eczema — but format, timing, and frequency determine whether it works. Ointments for the most compromised skin, creams for daily maintenance, always applied within the two-to-three minute post-bath window, at least twice daily regardless of skin state. No emollient addresses the filaggrin deficit and Th2 immune activity driving eczema internally — but with the right product applied at the right time with the right frequency, it gives the skin's own repair processes the best possible conditions to work within.
In short:
Helps repair the skin barrier
Reduces dryness and itching
Can prevent flare-ups
Needs to be done consistently
Not a cure on its own
Moisturising is the foundation of eczema care—and without it, managing symptoms becomes much harder. But while it’s essential, it’s not the full solution.
Supporting your skin from within can help reduce flare-ups and improve long-term resilience.
