What is Eczema?

Eczema is a chronic inflammatory skin disorder that results in itchy, red, and dry skin. It is a complex condition influenced by genetic, environmental, and immune system factors. While eczema is not contagious, its visible symptoms can affect self-esteem and social interactions.

Types of Eczema

• Atopic dermatitis: The most common type, often linked to allergies, asthma, and a family history of skin conditions.

• Contact dermatitis: Caused by skin reactions to irritants or allergens.

• Dyshidrotic eczema: Characterized by small, itchy blisters on hands or feet.

• Nummular eczema: Circular patches of irritated skin.

• Seborrheic dermatitis: Often affects scalp and face, sometimes called dandruff in mild cases.

Fact: Atopic dermatitis affects up to 20% of children globally and about 3% of adults.

Causes and Triggers of Eczema

The exact cause of eczema is complex, involving interactions between genetics, immune function, and environmental factors.

Genetic Factors

• Family history of eczema, asthma, or allergic rhinitis increases susceptibility

• Defects in the skin barrier protein filaggrin can lead to dry, sensitive skin

Immune System Dysfunction

• Overactive immune responses can cause inflammation and hypersensitivity reactions

• Exposure to allergens may trigger flare-ups

Environmental Triggers

• Harsh soaps, detergents, or skincare products

• Extremes of temperature or humidity

• Dust mites, pet dander, pollen, and mold

• Stress and emotional factors

Lifestyle Factors

• Poor hydration or diet lacking essential fatty acids

• Frequent scratching leading to skin barrier damage

Avoiding triggers and maintaining skin hydration are key preventive strategies.

Symptoms of Eczema

Symptoms vary depending on age, skin type, and severity.

Common Symptoms

• Dry, scaly, or cracked skin

• Intense itching (pruritus)

• Red or brownish-gray patches

• Oozing, crusting, or thickened skin due to scratching

• Skin discoloration in chronic cases

Signs of Severe Eczema

• Widespread inflammation (Inflammation and blocked pores can also cause other skin conditions such as acne, which shares some triggers with eczema like stress and hormonal changes. Learn more about its symptoms and treatments in our article on Acne: Causes, Symptoms, Treatment & Prevention.

• Painful or bleeding skin

• Secondary infections from bacteria or viruses

• Sleep disturbances due to constant itching

Early recognition of symptoms can prevent worsening and reduce complications.

Risk Factors

Certain factors make individuals more susceptible to eczema:

• Family history of eczema, asthma, or allergies

• Living in urban areas with pollution

• Dry climates or extreme weather changes

• Young age (children under 5 are most commonly affected)

• Weakened immune system or chronic stress. Like eczema, alopecia areata is another condition linked with immune system imbalance. If you’re interested in how autoimmune issues affect the skin and hair, check out our guide on Alopecia Areata: Causes, Symptoms & Treatment.

Awareness of risk factors allows for proactive management and early intervention.

Diagnosis

A proper diagnosis involves clinical evaluation and history-taking.

Medical Assessment

• Physical examination of affected skin

• Detailed medical and family history

• Assessment of environmental exposures and lifestyle factors

Laboratory and Allergy Tests

• Patch tests to identify allergens

• Blood tests for immune markers or IgE levels

• Skin biopsy in rare or atypical cases

Accurate diagnosis differentiates eczema from other skin conditions like psoriasis, fungal infections, or contact dermatitis.

Treatment of Eczema

Eczema treatment focuses on reducing inflammation, relieving itching, and repairing the skin barrier.

Home Care and Lifestyle Management

• Use gentle, fragrance-free cleansers and moisturizers 

• Apply moisturizers immediately after bathing to lock in hydration

• Wear soft, breathable clothing and avoid wool or synthetic irritants

• Manage stress to reduce flare-ups 

Medical Treatments

• Topical corticosteroids: Reduce inflammation and itching

• Calcineurin inhibitors: Alternative to steroids for sensitive skin areas

• Biologic injections: For moderate to severe cases (under supervision)

• Antibiotics or antivirals: For secondary infections

• Phototherapy: Controlled UV light exposure for persistent eczema

Complementary Therapies

• Wet wraps to soothe inflamed skin

• Oatmeal baths to relieve itching

• Essential fatty acid supplementation (Omega-3s) with medical guidance

Combining medical treatments with consistent skin care routines produces the best results.

Prevention and Daily Skin Care

• Maintain consistent moisturization routines

• Avoid known irritants and allergens

• Limit long, hot showers; prefer warm water

• Use gentle, fragrance-free laundry detergents

• Keep nails short to minimize skin damage from scratching

• Manage stress, diet, and sleep to support immune function

Preventive measures reduce flare-ups and improve long-term skin health.

Complications of Eczema

• Secondary infections (bacterial or viral)

• Chronic itching leading to sleep loss and fatigue

• Skin thickening and discoloration over time

• Emotional stress, anxiety, or depression due to appearance and discomfort

• Persistent scratching can break the skin barrier and increase the risk of bacterial infections like boils and carbuncles. If you want to know more about how these infections occur and how they’re treated, read Boils and Carbuncles: Causes, Symptoms & Treatment.

Early intervention and consistent care prevent these complications.
