Eczema: Causes, Symptoms, and How It Affects the Skin

Eczema: Causes, Symptoms, and How It Affects the Skin

Eczema is a common skin condition that affects the skin’s ability to protect itself.

It can develop at any age.
It may appear in babies, children, or adults.
For some people, symptoms are mild and occasional.
For others, eczema can be long-lasting and difficult to control.

Although it often looks similar on the surface, the reasons behind it — and the way it behaves — can vary from person to person. Understanding what it is, and how it affects the skin, helps explain why gentle, consistent care matters.

This page is your central guide to understanding eczema. It explains what eczema is, why it happens, how it affects the skin, and how symptoms can vary by age, trigger, and body area. Throughout the guide, you’ll find links to more detailed pages on specific eczema types, causes, and care approaches.

If you’re exploring a specific cause, trigger, or care approach, this guide links to more detailed pages below to help you go deeper where needed.

What Is Eczema?

It is linked to a weakened skin barrier.

The skin barrier is the outermost layer of the skin.
Its role is to lock moisture in and protect the body from irritants, allergens, and bacteria.

When this barrier does not function properly, the skin loses moisture more easily and becomes vulnerable to irritation and inflammation.This process is explained in more detail in our guide to skin barrier function and healing.

Over time, repeated inflammation leads to many of the symptoms commonly associated with eczema.

It is not contagious. It cannot be passed from one person to another through touch or contact.

Types of Eczema and Where It Appears

 

Atopic Eczema (Atopic Dermatitis)

Atopic eczema (also called atopic dermatitis) is the most common form. It is linked to a weakened skin barrier, which allows moisture to escape and irritants to enter more easily.

It often begins in childhood but may continue into adulthood or appear later in life.

Infant and Baby Eczema

Infant eczema is also a common form that appears in babies and young children. It often affects areas such as the cheeks, scalp, arms, legs, and body.

Although it can be distressing for parents, many children improve as their skin barrier strengthens with age.

Dyshidrotic Eczema

Dyshidrotic eczema affects the hands, fingers, feet, and toes. It often causes small blisters, itching, and soreness, especially during flare-ups. Triggers may include stress, sweating, or exposure to irritants.

Facial and Eyelid Eczema

The condition affects areas where the skin is thinner and more sensitive, including the cheeks, eyelids, and around the eyes. Because facial skin reacts easily, symptoms may flare in response to fragrances, skincare products, or environmental triggers.

Contact Dermatitis (Irritant or Allergic )

Contact dermatitis occurs when the skin reacts to an irritant or allergen it comes into contact with, such as soaps, fragrances, or detergents.

Symptoms usually appear only where contact occurs.

Learn more about Contact Dermatitis.


Seborrheic Dermatitis (Eczema in Oily Areas)

Seborrheic dermatitis is often confused with dandruff.

It tends to affect:

  • The scalp

  • The eyebrows

  • The sides of the nose

  • Behind the ears

It is associated with oil-producing areas of the skin and may flare in colder months or during periods of stress.

In oily areas of the skin, eczema-like symptoms may behave differently, which is discussed in more detail in our guide to seborrhoeic dermatitis.


Can You Have More Than One Type of Eczema?

Yes.
Many people experience overlapping forms, or symptoms that change over time.

For example:

  • Atopic eczema may appear alongside contact dermatitis

  • Facial eczema may flare alongside seborrheic dermatitis

  • Hand eczema may involve both dyshidrotic and irritant triggers

This is why the management often focuses on supporting the skin barrier, reducing triggers, and using gentle, fragrance-free skincare.


Why Identifying the Type of Eczema Matters

Although the symptoms may look similar, different types of eczema often need slightly different care approaches.

Knowing the type and location can help you:

  • Avoid common triggers

  • Choose gentler skincare

  • Apply moisturisers more effectively

  • Seek medical advice when needed

If symptoms are severe, spreading, oozing, or not improving, it’s always best to speak with a GP or dermatologist.


Common Symptoms of Eczema

Symptoms can look different depending on skin tone, age, and the area of the body affected…

Common symptoms may include:

    • Persistent dryness

    • Itching, which may range from mild to severe

    • Red or inflamed patches

    • Skin that feels tight, sore, or uncomfortable

    • Flaking, scaling, or cracking

In some cases, the skin may ooze or crust during flare-ups.
In others, symptoms may remain subtle but ongoing.

Itching is often the most disruptive symptom.
Scratching can further damage the skin barrier and increase irritation, creating a cycle that is difficult to break.

Why Eczema Develops

The condition does not have a single cause.

One common cause of eczema symptoms is contact dermatitis, which happens when the skin reacts to irritants or allergens it touches.

Eczema can also overlap with sensitive skin, where the skin barrier reacts easily to products, weather, or daily care routines.

Instead, it usually develops due to a combination of factors, such as:

    • A naturally weaker skin barrier

    • Genetic tendencies

    • Immune system responses

    • Environmental influences

When the skin barrier is already vulnerable, everyday exposures such as soaps, detergents, fragrances, fabrics, stress, or weather changes can trigger inflammation.

These triggers are explained in more detail in our guide to common  triggers.
This is why it often follows a pattern of flare-ups and calmer periods, rather than remaining constant.


How Eczema Affects Different Areas of the Body

The condition does not behave the same way across all areas of the skin.

The appearance and sensation of the condition can vary depending on location.

For example:

    • On the face, eczema may cause redness, dryness, or sensitivity

    • On the hands, it may lead to cracking and soreness

    • On the scalp, it can present as dryness or irritation

    • In skin folds, eczema may feel itchy and inflamed

For a deeper explanation, see our dedicated guide on facial eczema, including common triggers and care tips.


Eczema at Different Stages of Life

It can appear at any stage of life.

In infants, it often affects the cheeks, scalp, or body.
In children, it commonly appears in the bends of the arms and knees.
In adults, it may involve the hands, face, eyelids, or other sensitive areas.

For a deeper explanation, see our dedicated guide on baby eczema, including early signs and gentle routines.

Some people find their symptoms improve with age.
Others continue to experience the condition into adulthood.

Even when symptoms are mild or inactive, the skin may remain more sensitive than average.


Why Ongoing Skin Care Is Important

Because it is closely linked to a weakened skin barrier, daily skin care choices play an important role in symptom control.

Frequent washing, harsh cleansers, or fragranced products can increase irritation.
Gentle, consistent routines help reduce unnecessary stress on the skin.

For many people, managing the condition is not about quick fixes.
It is about long-term support and understanding how their skin reacts to everyday life.

Why Different Types Can Overlap

Many people experience features of more than one type.

For example, someone may have atopic dermatitis but also react to irritants, leading to contact dermatitis symptoms.
This overlap can make it feel unpredictable.

Understanding these distinctions helps guide appropriate care and avoids unnecessary treatments.


What This Means for Eczema Care

Because there are multiple subtypes, there is no single solution that works for everyone.

Care often depends on:

    • The type of eczema involved

    • The area of the body affected

    • The person’s age and triggers

Later sections of this guide will explore how it affects different age groups and body areas, and how gentle skin care principles apply across all types.


Eczema Triggers, Flare-Ups, and Supporting the Skin

Symptoms rarely stay the same all the time.

Most people experience periods when their skin feels settled, followed by flare-ups when symptoms worsen.
Understanding what triggers these changes can make eczema easier to manage over time.


What Is an Eczema Flare-Up?

A flare-up is a period when eczema symptoms become more active.

During a flare, the skin may:

    • Feel itchier than usual

    • Become red or inflamed

    • Appear drier or more sensitive

    • React more strongly to everyday products

Flare-ups can last days or weeks.
They often improve once triggers are reduced and the skin barrier is supported.


Common Triggers

Triggers vary from person to person.
However, several factors are commonly linked to flare-ups.

These include:

    • Soaps and harsh cleansers

    • Fragrances and essential oils

    • Laundry detergents

    • Synthetic or rough fabrics

    • Temperature changes

    • Stress or lack of sleep

A more detailed breakdown is covered in Sensitive Skin Triggers.

Reducing exposure to triggers does not cure the condition, but it can reduce how often flare-ups occur.


Why the Skin Barrier Matters During Flare-Ups

During a flare, the skin barrier is under increased stress.

Moisture escapes more easily.
Irritants penetrate the skin more readily.
Inflammation becomes harder to control.

This is why barrier-focused care is often recommended as part of long-term management.
The role of the skin barrier is explained further in our guide to skin barrier function and healing.


Supporting Eczema-Prone Skin Gently

Many people with eczema benefit from a simplified skin care routine.

This usually involves:

    • Using fragrance-free products

    • Avoiding harsh foaming cleansers

    • Moisturising regularly

    • Keeping routines consistent

Rather than switching products frequently, prone skin often responds better to steady, predictable care.

Some people choose to use fragrance-free, barrier-supporting creams developed specifically for sensitive or eczema-prone skin, such as Bragan Skincare’s Atopic Cream, which is designed to support dry, reactive skin without added fragrance.

This type of product is not a treatment for eczema itself, but it may help support the skin barrier when used as part of a broader routine.


Managing Flare-Ups Without Overloading the Skin

When it flares, it can be tempting to try multiple products at once.

However, adding too many new products can sometimes increase irritation.

A calmer approach often works better:

    • Reduce routines to the essentials

    • Avoid introducing new fragranced products

    • Focus on moisture and protection

    • Allow time for the skin to respond

For people with recurring flare-ups, using a consistent moisturiser formulated for sensitive skin can help maintain routine stability during difficult periods.


Stress and Eczema Flare-Ups

Stress does not cause it, but it can worsen symptoms.

Periods of emotional or physical stress may increase inflammation in the body.
This can make itching more intense and flare-ups more frequent.

Managing stress is not always easy, but recognising its impact can help explain changes in symptoms.


What Comes Next

Triggers and flare-ups are only one part of living with it.

In the next section, this guide will explore:

    • How eczema differs by age

    • How location on the body affects symptoms

    • Why care needs change for babies, children, and adults

This helps build a complete picture of the condition and how to support eczema-prone skin in everyday life.


Eczema by Age and Body Area

The condition does not affect everyone in the same way.

Age and body location both influence how eczema appears, how it feels, and how the skin responds to care.
Understanding these differences helps explain why eczema advice often varies from person to person.

This eczema hub provides the foundational overview, while each linked guide explores one aspect in greater detail.


Eczema in Babies

The condition often begins early in life.

In babies, it commonly appears on:

    • The cheeks

    • The scalp

    • The arms and legs

    • The body

Baby skin is thinner and more delicate than adult skin.
Because of this, dryness and irritation can develop quickly.

Early signs may include rough patches, redness, or frequent scratching.
These signs are explored further in our blog on early signs of eczema in babies.

Gentle skin care is especially important at this stage, as over-washing or fragranced products can easily worsen irritation.


Eczema in Children

As children grow, it often shifts location.

It commonly affects:

    • The bends of the elbows

    • Behind the knees

    • The wrists and ankles

    • The neck

Children may experience itching that interferes with sleep or concentration.
Scratching can damage the skin barrier and prolong flare-ups.

Some children see the problem improve with age.
Others continue to experience symptoms into adulthood.


Eczema in Adults

Adult eczema can appear in different ways.

Common areas include:

    • The hands

    • The neck

    • Areas exposed to frequent washing or irritation

Hand eczema is particularly common in adults due to repeated contact with water, soaps, or cleaning products.
This is discussed in more detail in our Eczema on Hands blog here.

Adult eczema may be long-standing or develop later in life, even in people who did not have eczema as children.


Facial Eczema

The skin on the face is thinner and more exposed than elsewhere on the body.

Facial may involve:

    • Redness

    • Flaking or scaling

    • Sensitivity

    • Tight or sore skin

It often affects areas such as the cheeks, eyelids, or around the nose.
Because facial skin reacts easily, care needs to be especially gentle.

Specific guidance is covered in our facial eczema blog here.


Eczema on the Scalp

On the scalp it can be difficult to identify.

It may cause:

    • Dryness or flaking

    • Itching

    • Sensitivity or soreness

For a deeper explanation, see our dedicated guide on scalp eczema and how it differs from dandruff.

Hair care products and washing routines often play a role in scalp symptoms.


Eczema in Skin Folds and Sensitive Areas

It can also affect skin folds, such as:

    • Behind the knees

    • Under the arms

    • Around the groin or buttocks

These areas may feel particularly itchy or uncomfortable due to heat and friction.

Because these regions are sensitive, symptoms can be distressing.
Supportive, fragrance-free care is often preferred.

More information on this topic is covered in Eczema on private parts.


Why Location Matters

Different areas of the body have different skin thickness, oil production, and exposure levels.

This means:

    • Some areas dry out more quickly

    • Some react more strongly to products

    • Some are more prone to friction or moisture

Understanding where it appears helps guide appropriate skin care choices and avoids unnecessary irritation.

What This Means for Managing Eczema

Care is not one-size-fits-all.

Effective support often depends on:

    • Age

    • Body location

    • Individual triggers

    • Skin sensitivity

Later sections of this guide will bring these factors together and explain how gentle routines can support eczema-prone skin across different life stages and body areas.


Gentle Care Principles for Eczema-Prone Skin

Eczema care is not about perfection.
It is about consistency, simplicity, and understanding how the skin behaves.

While it cannot always be prevented, gentle daily habits can help reduce irritation and support the skin barrier over time.


Focus on Supporting the Skin Barrier

Because it is closely linked to a weakened skin barrier, most care principles revolve around protecting and supporting that barrier.

This includes:

    • Keeping moisture in

    • Reducing exposure to irritants

    • Avoiding unnecessary disruption to the skin

Barrier support does not rely on strong or active products.
In fact, simpler routines are often better tolerated.


Keep Skin Care Routines Simple

Using too many products can overwhelm sensitive skin.

A gentle routine usually involves:

    • Mild, non-foaming cleansing

    • Regular moisturising

    • Avoiding frequent product changes

Introducing multiple new products at once can make it difficult to identify what the skin is reacting to.

Consistency matters more than variety.


Choose Fragrance-Free Products Where Possible

Fragrance is a common trigger for irritation.

Even natural or essential oil fragrances can cause problems for eczema-prone skin.

For this reason, many people prefer fragrance-free products designed for sensitive skin, such as those found in Bragan Skincare’s eczema-friendly range, which focuses on barrier support rather than masking symptoms with scent.

These products are not a cure, but they may help reduce unnecessary irritation as part of a wider care approach.


Moisturising Regularly Matters

Dry skin is more likely to itch, crack, and flare.

Moisturising regularly helps:

    • Reduce moisture loss

    • Improve skin comfort

    • Support recovery after flare-ups

Many people find it helpful to moisturise at least once or twice daily, especially after washing, when the skin is more prone to dryness.


Be Gentle During Flare-Ups

When it flares, the skin is already under stress.

During these periods:

    • Avoid scrubs or exfoliants

    • Avoid introducing new products

    • Reduce washing frequency where possible

    • Focus on calming and protecting the skin

Allowing the skin time to settle is often more effective than trying to “fix” it quickly.


Understand Personal Triggers

Triggers vary from person to person.

Common triggers include:

    • Soaps and detergents

    • Weather changes

    • Stress

    • Fabrics

    • Frequent washing

Keeping note of flare-ups and possible triggers can help identify patterns over time.

Next steps for eczema-prone skin

If dryness, tightness, or itching are a daily issue, many people choose fragrance-free, barrier-supporting creams designed for sensitive or eczema-prone skin.

Some people find that using a simple, fragrance-free moisturiser consistently helps reduce discomfort between flare-ups.


When to Seek Medical Advice

While many people manage the condition with daily skin care, there are times when professional advice is important.

This includes situations where:

    • Symptoms worsen suddenly

    • The skin becomes painful or infected

    • Eczema interferes with sleep or daily life

    • Symptoms do not improve with gentle care

A healthcare professional can help assess symptoms and recommend appropriate treatment where needed.
