Eczema

What is this disease?

Symptoms

• Intense Pruritus (Itching) moderate

  Persistent, severe itchiness that often worsens at night, causing an intense urge to scratch that further disrupts the skin barrier.

• Dry, Erythematous Skin Patches mild

  Red to brownish-gray patches of dry, inflamed, or scaly skin commonly appearing on hands, feet, ankles, wrists, neck, inner elbows, and knees.

• Small Raised Vesicles & Oozing moderate

  Small fluid-filled bumps or vesicles that may leak clear fluid when scratched and form yellowish crusts upon drying.

• Lichenification (Thickened Skin) moderate

  Thickened, leathery, and hyperpigmented skin patches resulting from chronic, repetitive rubbing and scratching.

• Painful Skin Fissures & Excoriation severe

  Deep, raw, and bleeding cracks or excoriations in the skin barrier that cause pain and significantly increase susceptibility to secondary infections.

Causes & risk factors

• Genetic Predisposition & Filaggrin Mutation genetic

  Inherited genetic variations affecting filaggrin protein production, which weakens the skin's outer epidermal barrier and allows moisture loss and allergen penetration.

• Immune System Hyper-Reactivity cause

  An overactive immune response where skin T-cells react excessively to minor environmental irritants, triggering chronic inflammation and localized tissue swelling.

• Environmental Chemical Irritants environmental

  Frequent contact with harsh soaps, alkaline detergents, synthetic fragrances, household solvents, or wool fabrics that strip natural protective skin lipids.

• Airborne & Contact Allergens trigger

  Exposure to dust mites, pet dander, mold spores, seasonal pollens, or specific food proteins that stimulate allergic immune pathways and provoke eczema flare-ups.

• Psychological Stress & Climate Extremes lifestyle

  Elevated stress hormones (cortisol) and rapid changes in temperature, cold dry air, or excessive perspiration that trigger or aggravate skin inflammation.

Diagnosis / tests

• Clinical Physical Examination

  A detailed visual assessment by a dermatologist to evaluate characteristic skin lesions, distribution patterns, and gather personal and family history of atopic conditions (asthma, hay fever, eczema).

• Skin Patch Testing (Contact Allergen Test)

  Application of small amounts of common environmental or chemical allergens under patches on the back for 48 hours to identify or rule out allergic contact dermatitis.

• Skin Biopsy

  Removal and microscopic examination of a small skin sample to rule out other inflammatory or malignant dermatological conditions, such as psoriasis, lichen planus, or cutaneous lymphoma.

• Total & Specific Serum IgE Blood Test

  Laboratory measurement of circulating Immunoglobulin E (IgE) antibody levels in the blood to assess overall allergic sensitization and immune reactivity.

• Skin Swab Culture (Bacterial & Viral Testing)

  Swabbing active, weeping, or crusted skin lesions to test for secondary bacterial (such as Staphylococcus aureus) or viral (Herpes simplex) infections.

First aid / immediate care

1. Cool Compress

   Apply a cool, damp cloth or compress to the itchy or inflamed skin area for 5–10 minutes to soothe irritation and reduce the urge to scratch.

2. Gentle Cleansing

   Wash the area gently with lukewarm water and a fragrance-free, soap-free cleanser. Avoid hot water and harsh scrubbing, as they strip moisture from the skin.

3. Apply Thick Moisturizer

   Pat the skin dry lightly (leaving it slightly damp) and immediately apply a thick, fragrance-free cream or ointment (like petrolatum) to lock in hydration

4. Protect the Area

   Cover the treated area with soft, breathable cotton clothing to prevent direct contact with external irritants, allergens, or accidental scratching.

5. Monitor for Infection Emergency

Treatment

Educational information only — not a personal prescription. Always consult a qualified clinician.

• Regular Emollient & Moisturizer Application self care

  Apply thick, fragrance-free creams or ointments (such as petroleum jelly or ceramides) immediately after bathing to repair the skin barrier and maintain hydration.

• Topical Corticosteroids medication

  Use prescribed topical hydrocortisone or stronger corticosteroid creams during flare-ups to reduce itching, swelling, and redness.

• Calcineurin Inhibitors & Non-Steroidal Topicals medication

  Apply topical calcineurin inhibitors (e.g., tacrolimus or pimecrolimus) or non-steroidal ointments to sensitive areas like the face and eyelids where steroid use is limited.

• Phototherapy (Light Therapy) therapy

  Expose the affected skin to controlled doses of narrow-band ultraviolet B (UVB) light under medical supervision for moderate-to-severe eczema unresponsive to topicals.

• Systemic Medications & Biologics therapy

  For severe cases, use targeted biologic injections (such as dupilumab) or oral immunosuppressants as prescribed by a dermatologist to control underlying inflammation.

Prevention / protection

• Regular & Consistent Skin Moisturization

  Apply a thick moisturizer, ointment, or cream at least twice daily—especially right after bathing—to lock in moisture and reinforce the skin's protective barrier.

• Identify and Avoid Personal Triggers

  Take note of factors that worsen flare-ups (such as harsh soaps, detergents, wool or synthetic fabrics, pet dander, pollen, or stress) and minimize exposure.

• Practice Gentle Bathing Habits

  Take short baths or showers using warm (not hot) water, and use mild, fragrance-free, non-soap cleansers instead of harsh antibacterial or scented soaps.

• Choose Soft, Breathable Clothing

  Wear loose-fitting clothes made from soft, natural fibers like 100% cotton, and wash new clothes with mild, dye-free detergents before wearing them.

• Maintain a Comfortable Indoor Environment

  Use a humidifier in dry conditions or air-conditioned spaces to prevent low humidity from drying out the skin, and keep indoor temperatures cool to minimize sweating.

Diet

Things to avoid

• Incorporate Anti-Inflammatory Foods diet

  Eat a balanced diet rich in omega-3 fatty acids (like salmon, flaxseeds, and walnuts), antioxidants, and colorful vegetables to help manage systemic inflammation.

• Eliminate Personal Trigger Foods & Excessive Sugar things to avoid

  Avoid high-sugar, heavily processed foods and known personal food allergens (such as dairy, eggs, soy, or nuts if diagnosed) that may spark eczema flare-ups.

• Practice Stress Reduction Techniques lifestyle

  Stress is a common trigger for eczema flare-ups. Engage in regular mindfulness, deep breathing exercises, yoga, or meditation to keep stress levels under control.

• Manage Sweat & Shower Promptly After Workouts exercise

  Exercise in cool environments to minimize heavy sweating, which can irritate sensitive skin. Shower immediately after physical activity with lukewarm water and reapply moisturizer.

• Stay Hydrated & Maintain Consistent Sleep Habits general advice

  Drink plenty of water throughout the day to support skin hydration from within, and prioritize 7–9 hours of restful sleep nightly to support overall skin repair and immune health
