Overview

Atopic dermatitis, more commonly known as eczema, is a condition that causes your skin to become itchy, red, dry, and cracked. It's a chronic condition, meaning it can last a long time and may come and go in flare-ups, but with care, it can be managed.

It's thought to be caused by a combination of factors, including your genes (it often runs in families), an overactive immune system, and issues with your skin's barrier function. This barrier normally helps keep moisture in and irritants out, but with eczema, it doesn't work as well. Environmental factors can also play a role in triggering flare-ups.

Eczema can affect people of all ages, but it most often starts in early childhood, even in babies. While some children outgrow it, it can continue into adulthood or even start for the first time when you're older. We want you to know that eczema is not contagious. You cannot catch it from someone else, and you cannot give it to others.

Living with eczema can be frustrating and uncomfortable, and we understand that. The constant itch can disrupt sleep, affect concentration, and make daily activities challenging. It can sometimes lead to feelings of self-consciousness, but you are not alone in this.

Symptoms

You might experience a range of symptoms, which can vary from mild to severe. Here are some of the most common ones:

Intense itching (pruritus): This is often the first and most bothersome symptom, and it can feel worse at night.
Red to brownish-gray patches: These patches can appear anywhere but are common on the hands, feet, ankles, wrists, neck, upper chest, eyelids, and importantly, in the bends of the elbows and knees. In infants, the rash often appears on the face and scalp.
Dry, scaly, or cracked skin: Your skin might feel rough, look flaky, and be very sensitive.
Small, raised bumps: These bumps may leak fluid and then crust over, especially if scratched.
Thickened, leathery skin (lichenification): Over time, from chronic scratching and rubbing, the affected skin can become thick and tough.
Raw, sensitive, or swollen skin from scratching.
Symptoms can range - from a few small, mildly itchy patches to widespread inflammation and an itch that feels unbearable.
Certain things, like allergens (dust mites, pollen), irritants (soaps, detergents), stress, or even changes in weather - can trigger or worsen your symptoms.

Diagnosis

Diagnosing eczema usually involves a doctor carefully looking at your skin and asking about your symptoms and medical history. They'll want to know if you have a family history of eczema, asthma, or hay fever, as these conditions are often linked (this is sometimes called the "atopic triad").

There isn't one specific blood test to diagnose eczema. However, if your doctor suspects allergies are playing a significant role in your flare-ups, they might suggest allergy testing (like a skin prick test or blood test) to help identify potential triggers. Sometimes, though less commonly, a skin biopsy (taking a small sample of skin for examination) might be done to rule out other skin conditions.

Management & Treatment

Living with eczema can be frustrating, especially during a flare-up, but please know that there are many ways to manage and treat the itch and rash effectively. Finding the right approach for you or your child is key, and it often starts with gentle skin care at home.

The cornerstone of eczema management is to keep the skin hydrated and protected. This simple, powerful routine is often called "Soak and Seal."

Home Care and Self-Management

Moisturize, Moisturize, Moisturize! This is the most important step. Apply a thick, fragrance-free moisturizer several times a day, especially after bathing. Ointments (like petroleum jelly) and thick creams are generally more effective than thinner lotions because they do a better job of locking moisture in.
Take Short, Lukewarm Baths: Long, hot showers can strip the skin of its natural oils. Stick to 5-10 minute baths or showers in lukewarm water. Use a gentle, soap-free cleanser.
Pat, Don't Rub: After bathing, gently pat the skin with a soft towel, leaving it slightly damp.
Seal in the Moisture: Apply moisturizer within three minutes of bathing to lock in hydration. If you are using a prescription topical medication, apply that first, then cover it with moisturizer.
Cool Compresses: Applying a cool, wet cloth to itchy areas can provide quick relief from the urge to scratch.

Over-the-Counter (OTC) Options

For mild eczema, you may find relief with products from your local pharmacy:

Mild Corticosteroid Creams: Low-strength hydrocortisone (0.5% or 1%) creams or ointments can help reduce redness and itching. These are meant for short-term use on small areas.
Antihistamines: If itching is making it hard to sleep, an oral antihistamine like diphenhydramine (Benadryl) might help, though it can cause drowsiness. Non-drowsy options are available for daytime relief.

When Prescription Treatments Are Needed

If your eczema doesn't improve with home care and OTC products, it's time to see your doctor. They can create a more personalized treatment plan, which may include:

Prescription Topical Steroids: These are stronger than their OTC counterparts and are very effective at calming inflammation. Your doctor will prescribe the right strength for the affected area and duration of use.
Topical Calcineurin Inhibitors (TCIs): These are non-steroidal prescription creams and ointments (like pimecrolimus and tacrolimus) that work by calming the immune system in the skin. They are often used for sensitive areas like the face, eyelids, and skin folds.
Other Non-Steroidal Topicals: Newer medications, such as PDE4 inhibitors (Crisaborole) or JAK inhibitors (Ruxolitinib), can also target inflammation in the skin.
Phototherapy (Light Therapy): For widespread or persistent eczema, treatment with specific types of ultraviolet (UV) light under medical supervision can be very helpful.
Systemic Medications: For severe, hard-to-treat eczema, a doctor may prescribe medications that work throughout the body. These can be pills or injections, such as biologics or oral JAK inhibitors, that target the specific sources of inflammation.

It can take some time to see improvement, and what works for one person might not work for another. Be patient with the process and keep open communication with your healthcare provider. If a treatment isn't working or is causing side effects, let them know so you can explore other options together.

Duration & Outlook

Eczema is typically a chronic condition, which means it tends to be long-lasting. Many people experience periods when their symptoms flare up, followed by periods when their skin clears up or improves significantly (this is called remission). It's a condition that often requires ongoing attention.

For many children, eczema improves or even disappears as they get older, though their skin may remain sensitive or prone to dryness. For others, it can persist into adulthood, or it might even start later in life. With careful management and an understanding of what triggers your flare-ups, most people can control their symptoms and maintain a good quality of life.

It's important to watch for warning signs for complications, such as a skin infection. Look out for increased redness, warmth around the rash, pus-filled bumps, yellow or honey-colored crusts, or if you develop a fever. If you notice any of these, it's important to see a doctor.

Prevention

While you might not be able to completely prevent eczema if you're genetically predisposed, you can take many steps to help reduce the frequency and severity of flare-ups and keep your skin feeling more comfortable.

Moisturize your skin regularly - at least twice a day. Use a fragrance-free, hypoallergenic moisturizer, especially after bathing, to lock in moisture and support your skin's barrier.
Try to identify and avoid your personal triggers - This could include certain soaps, detergents, fabrics (like wool or some synthetic fibers), allergens (like dust mites, pollen, pet dander), stress, or even specific foods for some individuals.
Take lukewarm (not hot) baths or showers - and limit them to about 10-15 minutes. Hot water can strip your skin of its natural oils.
Gently pat your skin dry with a soft towel after bathing – don't rub. Apply moisturizer while your skin is still slightly damp.
Choose mild, fragrance-free cleansers - instead of harsh soaps that can dry out or irritate your skin.

Causes & Triggers

The exact cause of eczema isn't fully understood, but it's believed to be a complex mix of genetic and environmental factors. Your genes can affect how well your skin barrier works; if it's not working optimally, your skin can lose moisture more easily and become more vulnerable to irritants and allergens from the environment. An overactive immune system response in the skin also plays a key role in the inflammation you see and feel.

Common triggers can vary from person to person, but here are some frequent ones and how you might avoid them:

Irritants: Soaps, detergents, shampoos, disinfectants, and even some natural juices from fruits, vegetables, or meats.
- How to avoid them: Use mild, fragrance-free products. Wear protective gloves when cleaning or handling potential irritants.
Allergens: Common environmental allergens include dust mites, pet dander, pollens, and molds. Food allergens can also be a trigger for some, particularly young children.
- How to avoid them: Reduce exposure to known allergens (e.g., regular cleaning, using allergen-proof bedding). If you suspect food allergies, discuss this with your doctor or an allergist.
Climate and Temperature: Hot weather, high or low humidity, and even sweating can trigger flare-ups. Sudden changes in temperature can also be a factor.
- How to avoid them: Try to dress in layers so you can adjust to temperature changes. Avoid overheating and use a humidifier in dry indoor conditions if that helps you.
Fabrics: Wool and some synthetic fabrics can feel scratchy and irritate the skin.
- How to avoid them: Choose soft, breathable fabrics like cotton. Wash new clothes before wearing them.
Stress: While stress doesn't directly cause eczema, it can certainly make it worse or trigger a flare-up.
- How to avoid it: Learning and practicing stress-management techniques like gentle exercise, meditation, mindfulness, or engaging in hobbies you enjoy can be helpful.
Hormonal changes: Some women notice their eczema flares or worsens at certain times in their menstrual cycle or during pregnancy.

Individuals with a personal or family history of eczema, asthma, or hay fever (the "atopic triad") are more likely to develop eczema. Age is also a factor, as it's most common in children, but it can occur at any age.

When to see a doctor

It's always a good idea to consult with a doctor or a dermatologist if you're concerned about your skin. Specifically, you should seek medical advice if:

Your skin condition is causing significant discomfort, itching, or pain that affects your daily activities, your child's activities, or sleep.
You've tried over-the-counter remedies and good skincare practices, but your symptoms aren't improving, are spreading, or are getting worse.
You notice signs of a skin infection. These can include pus-filled blisters, yellow or honey-colored crusts on the rash, skin that feels hot to the touch, very red streaks spreading from the rash, or if you or your child develops a fever.
The rash is widespread over your body or your child's body.
You're unsure what's causing the skin problem and need a clear diagnosis to ensure you're on the right track.

A dermatologist is a specialist in skin conditions and can confirm if it's eczema, help identify your specific triggers, and and discuss a comprehensive management plan tailored to your or your child's needs. Please remember, you don't have to manage this alone; help is available.

Frequently Asked Questions (FAQs)

Q: Is eczema contagious? A: No, eczema is absolutely not contagious. You cannot catch it from someone else, and you cannot pass it on to others.
Q: Can eczema be cured? A: Currently, there is no cure for eczema, but it can be very effectively managed. Many children find their eczema improves significantly or even disappears as they get older. For others, it can be a lifelong condition with periods of flare-ups and remission, but good control is often possible.
Q: Does stress cause eczema? A: Stress doesn't directly cause eczema to appear in the first place. However, if you already have eczema, stress can be a significant trigger for flare-ups or can make existing symptoms feel much worse. Learning to manage stress can be an important part of managing your eczema.
Q: Are there specific foods I should avoid if I (or my child) have eczema? A: While food allergies can sometimes trigger or worsen eczema flare-ups in some individuals (especially young children with more severe eczema), it's not a universal trigger for everyone. If you suspect a particular food is making eczema worse, it's best to discuss this with your doctor or an allergist. They can help determine if testing is needed. It's important not to eliminate foods from your or your child's diet without medical advice, as this could lead to nutritional deficiencies.
Q: Can I go swimming if I have eczema? A: Yes, people with eczema can usually go swimming. However, the chlorine in swimming pools or the salt in seawater can sometimes irritate eczema-prone skin for some individuals. A good tip is to rinse your skin with fresh, lukewarm water immediately after swimming and then apply a generous amount of your usual moisturizer while the skin is still damp.
Q: Will my child outgrow eczema? A: Many children with eczema do find that their symptoms improve significantly or even disappear completely as they get older, often by their teenage years. However, some will continue to have eczema into adulthood, or their skin may remain generally sensitive and prone to dryness even if the active eczema clears. Every child is different.
