What Is Eczema?
Eczema causes dry, itchy, and inflamed skin that can appear anywhere on the body. There are several types, and it can look different from person to person.
Definition and Overview
Eczema is a term for a group of conditions that lead to inflamed, red, and itchy skin. The most common type is atopic dermatitis, but other types include contact dermatitis and seborrheic dermatitis.
People with eczema often have patches of skin that may become rough, cracked, or blistered. These areas can cause discomfort and affect daily activities. Eczema is not contagious and can affect both children and adults.
Certain factors like a family history of allergies, asthma, or hay fever can make people more likely to develop eczema. Dry climates, stress, and exposure to irritants may cause flare-ups. For more details on the clinical features and causes, see this review of eczema.
Difference Between Eczema and Dermatitis
The words "eczema" and "dermatitis" are often used as if they mean the same thing. Both describe conditions that cause redness, swelling, and itching of the skin.
Eczema refers to a set of conditions, while dermatitis means skin inflammation in general. For example, atopic dermatitis and contact dermatitis are two specific types with different causes. Atopic dermatitis is linked to genetics and allergies, while contact dermatitis is usually triggered by touching an irritant or allergen.
The table below shows some differences:
| Condition | Main Cause | Symptoms |
|---|---|---|
| Atopic dermatitis | Genetic, immune system | Itchy, dry skin, rash |
| Contact dermatitis | Irritants/allergens | Red, inflamed patches |

How Eczema Develops
Eczema usually starts with dry, sensitive skin. A weak skin barrier allows irritants and allergens to enter. Immune cells in the skin react, causing inflammation and symptoms like redness, swelling, and itch.
Scratching breaks the skin and can make things worse. This might let bacteria or viruses get in, sometimes leading to infection.
Flare-ups may happen when people are exposed to triggers like soaps, detergents, harsh weather, or stress. Some research has found that certain everyday items like detergents do not make eczema worse for everyone, but they can still irritate sensitive skin. A detailed review of what may cause flares can be found in this systematic review on eczema triggers.
Common Types of Eczema
Eczema describes several skin conditions that cause redness, itching, and inflammation. Each type has its own symptoms and triggers. Understanding these differences helps people manage their symptoms better.
Atopic Dermatitis
Atopic dermatitis is the most common form of eczema. It often starts in childhood but can appear at any age. The skin becomes red, itchy, and dry. Many people notice patches on the face, elbows, knees, or hands. Flare-ups may occur due to certain soaps, allergens, or changes in weather.
This type is linked to other allergic conditions like asthma and hay fever. Genetics also play a big role. Scratching the skin can lead to infection or thickened patches. Moisturizers and prescription creams are common treatments, and avoiding triggers helps reduce flares.
Contact Dermatitis
Contact dermatitis happens when the skin reacts to something it touches. There are two main types: allergic and irritant. Allergic contact dermatitis is caused by substances like nickel, fragrances, or poison ivy. Irritant contact dermatitis develops after repeated contact with soaps, detergents, or cleaning products.
Symptoms usually show up as red, itchy, and sometimes blistered skin. The affected area is usually limited to where the skin made contact with the substance. Removing the trigger is the most important step. Mild cases may improve with over-the-counter creams, while severe reactions sometimes need medical attention. People who work with chemicals or have sensitive skin should watch for early signs.
Dyshidrotic Eczema
Dyshidrotic eczema causes small, itchy blisters on the sides of the fingers, palms, and sometimes the soles of the feet. The blisters are often filled with fluid and can cause burning or pain. This type is more common in adults, especially women.
Triggers may include stress, sweating, or contact with metals like nickel or cobalt. The blisters usually last a few weeks before drying and peeling. Keeping hands and feet dry and avoiding irritants can prevent flare-ups. Treatment often involves steroid creams to reduce itching and inflammation.
Nummular Eczema
Nummular eczema, also called discoid eczema, leads to round or oval patches of irritated skin. These spots can be red, scaly, and sometimes ooze fluid. It is more common in older adults and often appears after skin injuries or very dry skin.
Unlike other types, nummular eczema is not linked to allergies or asthma. Cold weather and low humidity can make it worse. The patches might be mistaken for ringworm, but a doctor can help diagnose and treat the condition. Treatment includes strong moisturizers, topical steroids, and avoiding triggers that dry out the skin.
Symptoms and Signs
Eczema can show up in many ways, but the most common symptoms are changes in the skin’s appearance and how it feels. The skin may become inflamed, irritated, or even infected if not managed quickly.
Rash and Patches
A hallmark of eczema is a persistent rash. This rash often appears as red or brownish-gray patches on the skin. These patches can show up anywhere but are more common on the hands, feet, ankles, wrists, neck, upper chest, eyelids, and inside the bends of elbows and knees.
The rash might look scaly, thick, or cracked. It can also form small, raised bumps that may leak fluid when scratched. Some people notice blisters or oozing areas, especially during flare-ups.
Children sometimes develop eczema on their cheeks and scalp. In adults, the patches may become rough and leathery from scratching or rubbing. These patches may become crusty or develop scabs if skin infections happen. More details can be found in this article about clinical symptoms of atopic eczema.
Itching and Itchy Skin
Itching is often the most bothersome symptom. The urge to scratch can become overwhelming, especially at night or after sweating. Scratching usually makes the skin worse by causing more irritation and sometimes breaking the skin open.
Itchy skin might come before any visible rash. Sometimes, the skin just feels tight or uncomfortable. Even light scratching can quickly turn a mild rash into a more severe one.
Ongoing itching often leads to thickened skin. Over time, scratching can leave lasting marks or dark spots. If the skin barrier breaks down, there’s a higher risk for skin infections. For an overview of itching as a symptom in eczema, visit this article on symptoms in atopic eczema.
Redness and Swelling
Inflamed areas appear as bright red or pink patches, showing that the skin is irritated. Swelling may occur, especially if there is a lot of scratching or if a skin infection develops.
This redness can be especially visible in people with lighter skin. In those with darker skin, inflamed patches might look dark brown, purple, or gray instead of red. The skin may feel warm or tender to the touch.
Severe swelling and redness can point to an active infection, which may need medical attention. Sometimes, the area can ooze pus or fluid, signaling the need for treatment. To learn about the way eczema signs are measured, see this guide about clinical signs of atopic eczema.
Causes and Triggers
Eczema has many causes and is made worse by different triggers. Genetics, problems with the immune system, and factors in the environment all play a role. Everyday items like soaps, detergents, and some foods can make symptoms worse.
Genetics and Immune System
Some people are more likely to get eczema because of their genes. Children often get it if their parents have eczema, asthma, or hay fever. Certain genes make the skin barrier weaker, which lets moisture out and irritants in.
The immune system in people with eczema overreacts to things like allergens and even small injuries to the skin. This causes inflammation, itching, and redness. The way the body responds is not the same for everyone. Eczema can show up at any age, but it often starts in childhood.
Problems with both genes and the immune system often make the skin more sensitive and likely to react to common triggers.
Environmental Factors
Many things in the environment can trigger eczema. These include sudden changes in weather, dry air, heat, humidity, and sweating. When the air is very dry, the skin can lose moisture and become itchy or cracked.
Pollutants like tobacco smoke, fumes, and even dust can make eczema worse. Stress is another trigger, since it can change how the immune system works, leading to more inflammation and flares. Contact with certain fabrics, especially wool or rough textiles, may also worsen symptoms, which is noted in systematic reviews.
Being in crowded or hot places where people sweat more can also trigger itching and outbreaks.
Irritants and Allergens
Everyday products often contain irritants that can harm sensitive skin. Soaps, shampoos, bubble baths, detergents, and cleaning sprays are common culprits. They can strip away oils from the skin, making it dry and less able to defend against germs or other threats.
Common irritants include:
- Harsh soaps and cleansers
- Laundry detergents
- Fragrances and perfumes
- Household cleaners
Allergens can also trigger eczema flares. These may include dust mites, pollen, mold, or pet dander. Some people react to specific foods, such as eggs, milk, peanuts, or wheat. Food allergies are more common in young children with eczema, according to medical studies.
Avoiding known irritants and allergens can prevent many flares and help keep symptoms under control.
Risk Factors
Eczema risk depends on factors like age and other health conditions. Some people are more likely to develop eczema because of their age or existing medical issues.
Age Group Differences
Eczema can affect anyone, but it is most common in young children. Babies and preschool-aged children have the highest risk. Some children outgrow eczema as they get older, while others continue to have symptoms into adulthood.
Among adults, eczema is less common, but the risk remains. Adult eczema may be triggered by stress, environmental factors, or workplace exposures. Adults with eczema may also have a higher risk for certain health issues, including cardiovascular problems.
Related Conditions
People with a family history of allergies, asthma, or hay fever have a greater chance of getting eczema. Many people with eczema also have one or more of these conditions, a connection known as the atopic triad.
Eczema is also linked to mental health, especially anxiety and depression. The stress from itching and discomfort can affect mood and emotional well-being. Managing related health issues like allergies and mental health may help reduce eczema flares.
Diagnosis of Eczema
A dermatologist uses several methods to diagnose eczema. Physical signs, patient history, and identifying potential triggers are important.
Physical Examination
During a physical exam, the dermatologist looks for signs of eczema such as redness, dryness, swelling, and itching. Commonly affected areas include the hands, arms, face, and behind the knees.
Doctors ask about when the rash started and how it has changed. They also check for a personal or family history of allergies, asthma, or hay fever. Sometimes, a patch test is done to see if a contact allergen is causing the reaction.
Eczema is usually diagnosed based on the skin's appearance and the person's symptoms. Rarely, a skin sample (biopsy) is taken to rule out other conditions.
Checklist used in diagnosis:
- Location of skin changes
- Itching and dryness
- Pattern of flare-ups
- Personal or family history of allergies
Identifying Triggers
Finding eczema triggers is important for controlling flare-ups. Common triggers include soaps, detergents, fabrics, weather changes, stress, and sweating.
A dermatologist may ask patients to keep a diary of symptoms and daily activities. This helps identify if a food, product, or habit is making eczema worse. Sometimes, patch tests are used to find if contact with certain substances is causing eczema.
Avoiding triggers can reduce how often symptoms return. Allergy testing may help when standard treatments are not effective.
Treatment Options
Eczema treatment aims to reduce symptoms and prevent flares. The best approach combines medications, lifestyle changes, and regular skin care.
Topical Medications
Topical medications are often the first treatment. Doctors commonly prescribe topical corticosteroids to control inflammation and itching. These creams or ointments come in different strengths and are applied to affected areas once or twice a day.
Calcineurin inhibitors like tacrolimus or pimecrolimus are sometimes used, especially for sensitive areas like the face or skin folds. These do not thin the skin. Overuse of steroids can cause side effects such as thinner skin and stretch marks.
Nonsteroidal anti-inflammatory creams may also be used. Patients should follow their doctor's instructions and report any new symptoms. Proper use of topical treatments often improves the skin and reduces the need for stronger medicines (more about topical treatments).
Systemic and Oral Medications
For severe eczema or cases that do not respond to topical treatments, doctors may recommend systemic or oral medications. These include oral corticosteroids and immunosuppressive drugs such as cyclosporine, methotrexate, or azathioprine. Oral steroids should only be used for short periods because long-term use can cause serious side effects.
Antihistamines may help with itching, especially at night. Some patients may be prescribed newer injectable medicines called biologics, like dupilumab, which target specific immune system pathways.
Doctors consider a person’s age, medical history, and symptom severity when choosing a medication. Regular check-ups may be needed to monitor side effects and adjust treatment (learn more about oral medications).
Phototherapy
Phototherapy, or light therapy, uses certain types of ultraviolet (UV) light to treat eczema. It is often used when topical or oral treatments do not work. Narrowband UVB is the most common type, as it is less likely to damage the skin.
Phototherapy is usually done in a doctor’s office several times a week. Each session only takes a few minutes. Doctors monitor the skin to avoid burns and other risks. Over time, phototherapy may reduce the need for medications.
Side effects can include dryness, redness, or increased risk of skin aging. Regular appointments are needed for the best results (phototherapy details).
Moisturizing
Moisturizing is a key part of managing eczema. Using fragrance-free creams or ointments helps keep skin hydrated and repair the skin barrier. Moisturizers should be applied right after bathing, while the skin is still damp.
Switching to gentle, mild cleansers and taking short, lukewarm baths can help reduce dryness and itching. Applying a thick layer of moisturizer several times a day helps prevent flare-ups.
Wet wrap therapy can boost the effect of moisturizers. In this method, a layer of wet gauze is wrapped over the lotion and covered by a dry layer. This helps heal very dry or inflamed skin (emollient therapy explained).
Eczema Management and Prevention
Managing eczema depends on gentle daily care and smart choices to avoid skin irritation. Good habits lower the chance of flares and help keep skin from getting dry or itchy.
Daily Skin Care Routine
A steady skin care routine protects the skin barrier and reduces eczema flare-ups.
- Moisturize often: Apply fragrance-free cream or ointment right after bathing and several more times each day to keep skin moist.
- Gentle cleansing: Use lukewarm water and mild, unscented cleansers. Harsh soaps can strip the skin’s natural oils and cause irritation.
- Bathing habits: Take short showers or baths, no longer than 10 minutes. Avoid very hot water, which dries out skin.
- Pat, don’t rub: Gently pat skin dry with a soft towel after washing. Rubbing can damage sensitive skin.
- Choose soft fabrics: Wear loose, breathable clothing like cotton. Avoid rough materials such as wool.
Following these steps every day supports the skin’s barrier and helps prevent eczema from returning. See more on evidence-based skin management for eczema.
Avoiding Triggers and Irritants
Avoiding triggers can help prevent flares.
- Avoid harsh products: Many detergents, soaps, and cleaning sprays contain chemicals that irritate the skin. Use gentle, fragrance-free products.
- Avoid dry air: Use a humidifier in winter or in dry climates to add moisture to the air.
- Watch for irritation: Wool clothing, strong perfumes, and certain skincare additives can irritate skin. Choose milder alternatives.
- Be aware of weather changes: Sudden drops in temperature can dry the skin and trigger flare-ups.
Limiting contact with irritants and maintaining a healthy environment can reduce itchiness and help stop new flare-ups. Learn more about managing eczema triggers and prevention at guidelines for hand eczema.
Complications and When to See a Doctor
Eczema can lead to more than just dry, itchy skin. Sometimes, it causes infections or long-term problems that need medical care.
Infections and Skin Damage
Eczema weakens the skin’s protective barrier, making it easier for bacteria like Staphylococcus aureus to cause infection. Signs of infection include increased redness, warmth, swelling, pain, yellow crusts, or oozing. Blisters, pus, or a burning feeling can also appear.
Scratching can break the skin, raising the risk for bacterial infection and sometimes viral infections, such as herpes simplex, that may spread quickly.
See a doctor if skin becomes sore, hot, swollen, or has pus. Early treatment helps prevent serious problems. Learn more about eczema complications at Complications and diseases associated with atopic eczema.
Severe Eczema and Long-Term Effects
Severe eczema can make skin very dry, thick, or leathery. Deep cracks or small wounds may develop and not heal well.
Long-term outbreaks can affect sleep, concentration, and stress levels. Constant itching and pain can interfere with daily activities.
Medical treatment is needed if eczema worsens quickly, covers large areas, or does not improve with over-the-counter treatments. Children and adults with frequent flare-ups should see a dermatologist to check for complications and review the treatment plan. For more on managing severe eczema, read GPs' experiences of diagnosing and managing childhood eczema.
Impact on Quality of Life
Eczema can cause itching, pain, and irritation that affect daily life. Living with eczema often brings challenges at home, in school, and in social situations.
Social and Emotional Effects
Eczema can lead to embarrassment because of visible rashes, redness, or scaly skin. Children and adults may avoid certain activities or clothing to hide their symptoms and may feel left out.
Kids with eczema sometimes have trouble making friends or are teased. Adults may struggle with self-esteem, especially if eczema is on the face or hands. Eczema's impact on quality of life can be significant, affecting relationships.
Missing school, work, or hobbies is common during severe flare-ups, leading to frustration and less participation in favorite activities. Fewer social experiences can make mood and self-image worse over time.
Mental Health Considerations
People living with eczema often feel stress, sadness, or anxiety. The constant itch and discomfort can disturb sleep, making it harder to focus or feel rested. These sleep problems can lead to mood swings and irritability.
Research shows that eczema and mental health issues such as depression often go together. Children with eczema may feel lonely or helpless. Adults have a higher risk for anxiety and depression, especially if eczema is severe or long-lasting.
Worrying about flare-ups or treatments may also increase stress. Some people fear being judged because of their skin. Support from family, friends, and mental health professionals can help with both the physical and emotional challenges of eczema.
Eczema in Different Body Areas
Eczema symptoms and triggers often change depending on where it appears. Areas like the face, hands, and feet are more sensitive and may react differently to irritants or treatments.
Face and Neck
Eczema on the face and neck is often more noticeable and can be uncomfortable due to itching, dryness, and redness. The skin in these areas is thinner, making it more sensitive to soaps, lotions, and weather changes. Flare-ups may cause swelling around the eyes, scaly patches, and small cracks along the sides of the nose or lips.
Common triggers include sweat, makeup, or shaving products. Sun or cold weather can make symptoms worse. Use gentle, fragrance-free facial cleansers and moisturizers. Doctors may recommend mild topical steroids or calcineurin inhibitors for these sensitive areas. Regular moisturizing and protecting the skin from harsh weather can help prevent flare-ups. More information on eczema in different body areas can be found in this medical overview.
Hands and Elbows
Eczema is common on the hands and elbows, especially for people who frequently wash their hands or use cleaning products. Hands are exposed to more irritants and environmental stress, which can lead to dryness, redness, cracking, and blisters. Elbows may develop rough, thickened patches that itch or burn.
Contact with water, soaps, and chemicals are major triggers. Wearing cotton gloves during cleaning and moisturizing after washing hands are helpful steps. For elbows, applying thick ointments like petroleum jelly can help protect the skin. Some people may need prescription creams or to avoid certain jobs. Localized hand eczema can greatly impact daily tasks and quality of life.
Legs and Feet
Eczema often affects the legs, knees, ankles, and feet. Itching and scaly patches on the lower legs or behind the knees are common, especially in children. On the feet and ankles, eczema can cause cracked heels, peeling, and soreness. Tight shoes or socks that don’t breathe can make symptoms worse.
Dry skin from hot showers or cold air is another problem. Keeping legs and feet clean but not overly dry is important. Apply moisturizing creams right after bathing to lock in moisture. Some people are sensitive to dyes or fabrics in socks, so cotton or other soft materials are better. Regularly check for signs of infection—like redness or oozing—since scratching can open the skin and increase infection risk.
Scalp and Ears
On the scalp, eczema may look like flaky scales, redness, and mild hair loss or thinning. The skin can itch and feel sore, especially around the hairline or behind the ears. Eczema also affects the ears, causing cracked, dry patches inside or around the ear canal.
Shampoos with harsh chemicals or fragrances can trigger symptoms. Use gentle, non-medicated shampoos and moisturizing sprays to manage dryness. Some people benefit from topical steroids or antifungal creams if the scalp is inflamed or infected. For ears, clean gently and avoid cotton swabs inside the ear canal. Protecting these areas from cold wind and wearing hats made of soft fabrics can help prevent symptoms from getting worse. For more details about eczema types and body sites, see this resource on eczema.
Living With Eczema
Managing eczema takes patience and consistent care. Daily routines, helpful resources, and support systems can make life easier for people with this condition.
Support Resources
Support resources include professional help, online communities, and patient organizations. Dermatologists provide guidance on treatment plans and help adjust medicines as symptoms change. They can recommend skin care routines and identify triggers.
For emotional support, many turn to online forums and local groups where people share experiences and advice. Organizations such as the National Eczema Association offer information, webinars, and helplines.
Connecting with others who face similar challenges can reduce feelings of isolation. Family and friends also help with daily tasks and encouragement. Adults and families who seek information and help often report better quality of life with eczema.
Tips for Daily Living
A few key steps can make each day smoother for people with eczema. Choose gentle, fragrance-free soaps and moisturizers to avoid irritation. Bathe with lukewarm water instead of hot to prevent dryness. Apply moisturizer right after bathing to lock in moisture. Use a humidifier in dry climates to add moisture to the air.
Wear soft, breathable clothing like cotton to reduce friction and itching. Avoid wool or rough fabrics. Try not to scratch, even when itching is strong. Keeping nails short helps prevent skin damage.
Managing stress through relaxation, routine, or talking with a counselor may also help, as stress can trigger flares. Small lifestyle changes and careful habits can make daily life with eczema more comfortable and help control symptoms.
Differences Between Eczema and Psoriasis
Eczema and psoriasis are both skin conditions, but they are not the same. Each has unique symptoms and triggers.
Location
- Eczema often appears in the creases of the elbows and knees.
- Psoriasis usually develops on the scalp, elbows, knees, and lower back.
Symptoms
- Eczema causes itchy, red, and sometimes oozing skin.
- Psoriasis leads to thick, silvery scales and well-defined, red patches.
Triggers
- Eczema can be caused by allergens, irritants, or stress.
- Psoriasis is linked to immune system issues and can be triggered by cold weather or infections.
Differences Table
| Feature | Eczema | Psoriasis |
|---|---|---|
| Itchiness | Very common | Can itch, but less intense |
| Scales | Rare or fine | Thick, silvery, and obvious |
| Edges | Blurry, less defined | Sharp and well defined |
| Age of Onset | Often in childhood | Can appear at any age |
For more on the differences, studies compare the clinical features of eczema and psoriasis. Some research looks at distinguishing them, especially when symptoms overlap or both appear together.
Eczema is known for dryness and sometimes clear fluid, while psoriasis patches are thicker and more scaly. Genes and immune response differences also set these conditions apart, with psoriasis showing greater up-regulation of metabolism-related genes.
Frequently Asked Questions
Eczema is a group of skin problems that cause dry, itchy, and sometimes inflamed skin. Treatments, triggers, and long-term outcomes can be different for each person.
What are the most effective treatments for managing eczema symptoms?
Topical corticosteroids are often prescribed to reduce redness and itching. Moisturizers and emollients help keep the skin hydrated and prevent flare-ups.
For severe cases, doctors may suggest non-steroid creams, oral medications, or light therapy. Keeping skin clean and avoiding triggers is important for daily care.
Can eczema be completely cured, and if so, how?
There is no known cure for eczema. Many people can control their symptoms with proper care and by avoiding triggers.
Some children may outgrow certain types, but adults generally manage flare-ups rather than achieve a total cure.
What are the common causes or triggers of eczema flare-ups?
Dry skin, stress, sweat, and changing weather can trigger eczema. Soaps, detergents, and fragrances are common irritants.
Allergens like pet dander, dust mites, and some foods may also lead to flare-ups. Identifying and avoiding each person’s triggers can help prevent problems.
Which creams and moisturizers are best for soothing eczema?
Thick creams and ointments that are fragrance-free and made for sensitive skin work best. Petroleum jelly and products with ceramides help lock in moisture.
Prescription creams, such as topical steroids or non-steroid anti-inflammatories, may be needed for severe symptoms. Consistent use of moisturizers is key for relief.
Is it possible to catch eczema from someone else, or is it non-contagious?
Eczema is not contagious. It cannot spread from person to person through touch, air, or any other contact.
It is related to genetics, immune responses, and environmental factors instead of infection.
How many types of eczema exist, and what are their distinct characteristics?
There are several types of eczema. Atopic dermatitis is the most common and often runs in families. Contact dermatitis occurs when the skin touches something irritating or allergenic.
Other types include nummular eczema, which causes coin-shaped spots, dyshidrotic eczema, which leads to blisters on the hands and feet, and seborrheic dermatitis, which affects the scalp and oily areas. Each type has its own pattern and triggers.
