Serums for Eczema-Prone Skin: Do You Need One and What to Look For?

If you have eczema-prone skin, you probably already have a moisturiser you rely on. So when your skin still feels tight, rough or uncomfortable, especially as Australian weather changes, it's natural to wonder whether a barrier serum would help, and which serum to use for eczema-prone skin.

The quick answer: a serum is optional, not essential.

A thoughtfully formulated serum can add targeted ingredients to your routine, but it shouldn't replace your everyday moisturiser. The key is choosing a simple, fragrance-free formula suited to sensitive skin, and understanding what it can realistically add.

Here's how to compare serum types, recognise useful ingredients, layer products and decide whether a serum belongs in your routine.

What does a serum do for eczema-prone skin?

A serum is a lightweight skincare product formulated to deliver selected ingredients in a concentrated format. For eczema-prone skin, the aim may be to provide additional hydration or support the skin barrier in areas that need extra attention.

Your skin barrier is the outermost layer of your skin, known as the stratum corneum. Think of it as a brick wall: skin cells are the bricks, while lipids, including ceramides, help form the mortar. When this barrier is less effective, water can escape more readily through a process called transepidermal water loss (TEWL), leaving skin feeling dry and tight.

A serum may complement your routine by:

• Attracting moisture: Humectants such as glycerin help draw water into the outer skin layer.
• Supporting barrier care: Ingredients such as ceramides and dexpanthenol have different roles in maintaining skin hydration and barrier function.
• Targeting particular areas: A lightweight formula may be convenient for dry patches on the hands, face or elbow creases.

A serum won't resolve eczema on its own, and not every serum suits every skin. Its value depends on the finished formula, the ingredients it contains and how your skin responds.

For a deeper explanation, read our guide to supporting the skin barrier with eczema.

Serum vs moisturiser for eczema: do you need both?

A serum and a moisturiser have different roles. If you choose to use both, the serum is an optional addition to your moisturising routine.

Moisturisers can contain humectants, emollients and occlusives. These ingredients attract water, soften the skin or help reduce moisture loss. So the ingredients matter more than whether the label says serum, cream or balm.

If your current moisturiser keeps your skin comfortable, you may not need another step. If particular areas remain dry despite consistent moisturising, a suitable serum may be worth considering.

If you're choosing between a serum and a moisturiser, go for the moisturiser first. Consistent use is more important than building a complicated routine.

Our guide to eczema cream vs ointment vs lotion vs balm explains how to choose a texture that suits your needs.

Which serum should you use for eczema-prone skin with a damaged barrier?

Look for a fragrance-free formula with a clear purpose, relevant ingredients and directions suited to your skin. Rather than searching for a product promising dramatic results, consider what your skin needs: hydration, softness or a simpler routine.

Ingredients to look for

Ceramides, cholesterol and fatty acids: These lipids contribute to the structure of the skin barrier. Some formulations combine them in specific ratios to support barrier care. If a brand mentions a lipid ratio, check that it applies to the specific product you're buying.

Dexpanthenol (provitamin B5): Helps skin hold on to moisture and supports its natural renewal. It's generally well tolerated in sensitive-skin products.

Glycerin: A well-established humectant that attracts water into the outer layer of skin. It can be useful in products designed for dehydrated skin.

Hyaluronic acid: A humectant that helps bind water. On dry skin, it is generally sensible to follow a hydrating serum with a moisturiser rather than relying on the serum alone.

Konjac root: A plant-derived ingredient and one of the two actives in Curezma's Barrier Repair Serum.

Ingredients to approach with caution

Not every popular facial serum is designed with eczema-prone skin in mind. Consider avoiding or seeking professional advice before using products containing:

• Fragrance and essential oils: These may irritate sensitive skin or trigger reactions in some people.
• Exfoliating acids, including glycolic, lactic and salicylic acid, particularly on irritated or cracked areas.
• Retinoids, including retinol: These can cause dryness and irritation, especially when introduced to sensitive skin.
• High-strength vitamin C: Some formulations may sting or irritate reactive skin.
• High-strength niacinamide: Higher concentrations may not be comfortable for everyone.
• Drying alcohols: Check the type and overall formulation rather than assuming every ingredient containing the word “alcohol” has the same effect.

An ingredient is not automatically unsuitable simply because it appears on this list. Your skin's condition, the concentration, the overall formula and the area of application all matter.

Barrier serum types compared: pros and cons

When comparing facial serum brands, focus on formulation, fragrance, ingredient transparency, testing, directions and value. These criteria are more useful than a universal ranking of brands.

Before choosing a product, ask five questions:

Is it fragrance-free? Are the key ingredients clearly identified? Are concentration claims provided where relevant? What testing supports its claims? And does its intended use match your needs?

In Australia, products that make therapeutic claims should be TGA-listed. Look for an AUST L number on the pack. A listing shows the product meets regulatory requirements, but it isn't a guarantee that it will suit your skin.

Choosing a facial serum for eczema-prone skin

Facial skin needs particular consideration, especially around the eyelids, nose and mouth, where irritation or cracking can make products uncomfortable.

Start with a simple, fragrance-free formula and avoid introducing several new skincare products simultaneously. If you use makeup or sunscreen, consider how the serum layers underneath them and whether the combined routine feels comfortable.

Do not apply a product close to the eyes unless its instructions specifically allow that use. Similarly, do not assume that a serum suitable for the body is automatically suitable for facial or eyelid skin.

What about seasonal changes in Australia?

During winter, indoor heating, cool winds and hot showers may leave skin feeling drier. In warmer weather, sweat, sunscreen and frequent swimming can make your routine feel different. Changes in temperature, humidity and daily activities can all affect how comfortable your skin feels.

Rather than changing your entire routine with every season, maintain regular moisturising, use gentle cleansing practices and adjust textures if needed. A serum may be useful as an additional step, but it is not a seasonal necessity.

Where does a serum go in the routine?

The usual rule is to apply products from the lightest to the richest texture, so a serum generally goes on before your moisturiser.

A general routine can look like this:

1. Cleanse: Use a gentle, fragrance-free cleanser and lukewarm water.
2. Apply serum: If appropriate for your skin and consistent with the product directions, apply it to the intended areas.
3. Moisturise: Apply your usual moisturiser to help maintain hydration.
4. Add an ointment if needed: A richer product may be useful on particularly dry areas.
5. Finish with sunscreen in the morning: Use a broad-spectrum sunscreen appropriate for your skin and apply it according to its directions.

Allow products to settle between layers if needed. If a serum pills, feels uncomfortable or interferes with sunscreen or makeup, simplify the routine and reassess whether the extra step is worthwhile.

How to introduce a new serum without upsetting your skin

Even products formulated for sensitive skin can cause a reaction in some people. Introducing a serum carefully helps you see how your skin responds.

• Patch test according to the product's instructions. Curezma's labels recommend testing a small area and observing it for 24–48 hours.
• Introduce one new product at a time.
• Begin at the frequency directed on the label rather than automatically using more product.
• Monitor for persistent burning, worsening redness, swelling or a new rash. Stop using the product if a reaction develops.
• Avoid experimenting with new skincare on severely irritated, broken or weeping skin without professional guidance.

A brief tingle can occur with some products, particularly on compromised skin, but it isn't a sign that a product is working. Persistent or worsening discomfort warrants stopping use and seeking advice. Our guide to why eczema cream stings explains how to tell a normal tingle from a reaction.

If eczema is worsening, affecting sleep or not responding to your usual care, speak with your GP or dermatologist. Skincare products are not a substitute for an appropriate eczema management plan.

Are serums OK for kids?

A serum designed for children, fragrance-free and used as directed, can be an optional extra for stubborn patches. Children don't automatically need a serum, and a consistent moisturising routine should remain the priority.

Before introducing one:

• Check the age guidance and instructions on the pack.
• Choose a product designed for children's skin rather than adapting an adult anti-ageing serum.
• Patch test as directed and monitor for discomfort.
• Ask your GP or maternal and child health nurse before introducing a new product to a baby, particularly if the skin is irritated or the diagnosis is uncertain.

Avoid experimenting with exfoliating acids, retinoids or fragranced products on a child's eczema-prone areas without appropriate professional advice.

For families exploring a targeted option, see our kids eczema serum, the Curezma Junior Eczema Barrier Repair Serum. The product's age guidance and directions should determine whether it is suitable for your child. For more on choosing products for your child, see our best eczema products for kids guide.

Where Curezma's Barrier Repair Serum fits

Curezma takes a science-led approach to everyday eczema care, combining formulation thinking with a routine-based approach. Founder and formulation chemist Aditi Mamtani brings more than 18 years of formulation experience, and the range was created by a parent and scientist.

Curezma's adult eczema barrier repair serum lists two active ingredients:

• Konjac root powder: 2 mg/g
• Dexpanthenol: 50 mg/g

The formulation is fragrance-free, paraben-free, and formulated without corticosteroids. The product directions recommend use morning and night on the intended areas. It's TGA-listed. We're also upfront that, because of its active ingredients, some people feel a tingling or slight stinging sensation on broken skin, which is why we recommend a patch test first.

Like any serum, it works best as part of a consistent routine alongside a good moisturiser.

In Curezma's clinical trial, run by researchers at Princeton (PCR-UK) with more than 370 participants, skin barrier function was among the outcomes measured, with participants using Curezma products as part of a regimen.

The serum is an optional step, not a replacement for moisturiser or medical care when needed.

Frequently asked questions

What does a serum do for eczema-prone skin?

A serum can deliver selected hydrating or barrier-supporting ingredients in a lightweight formula. Its usefulness depends on the formulation and your skin's needs. It works best as an addition to regular moisturising, not a replacement for it.

Can I use a serum instead of a moisturiser?

Generally, no. A serum and a moisturiser serve different purposes. If you can only manage one product, prioritise a suitable moisturiser and use it consistently.

Are serums OK for kids?

Some are designed for children, but a serum is not essential for every child. Check the age guidance, follow the label and seek advice from your GP or maternal and child health nurse before introducing a new product to a baby.

What ingredients should a barrier serum have?

Look for ingredients suited to your needs, such as glycerin, dexpanthenol, ceramides or other skin-identical lipids. Niacinamide and hyaluronic acid may also be appropriate for some people. Choose a simple, fragrance-free formulation and assess the finished product rather than relying on a single ingredient.

Where does a serum go in my routine?

Generally, serum goes after cleansing and before moisturiser, following the product's directions. In the morning, sunscreen comes after your skincare layers. If you use a full range from one brand, follow its recommended order.

A considered approach to eczema care

You do not need every skincare step to care thoughtfully for eczema-prone skin. Start with gentle cleansing, consistent moisturising and guidance appropriate to your needs. If particular areas need an additional layer, a well-chosen serum may be worth exploring.

Curezma's range is science-led, clinically tested and formulated without corticosteroids, created by a parent and scientist to work together as one simple routine. Explore the Curezma routine and find an approach that fits your skin, your family and everyday life.
