Eczema: Symptoms, Triggers, and What Actually Helps

Eczema (atopic dermatitis) is a chronic inflammatory skin condition characterised by intense itching, dry skin, and recurring flares of redness and rash. It affects an estimated 10–15% of children in India and a significant proportion of adults. It's not contagious and not caused by poor hygiene — it's a genetic skin barrier problem amplified by environmental triggers.

What Eczema Is and Why It Happens

The skin of people with eczema has a genetic impairment of the barrier function — mutations in the filaggrin gene and other barrier proteins mean the outermost layer doesn't seal properly. Water evaporates through the barrier too easily (increased transepidermal water loss), and irritants and allergens penetrate inward more easily than they should.

The result is skin that is chronically dry, prone to irritation, and hypersensitive to environmental triggers. The immune system in atopic individuals (those with eczema) also has a tendency toward inflammation — this is why eczema often accompanies allergic asthma and allergic rhinitis (the "atopic triad").

Eczema Symptoms

Chronic baseline:

• Dry, dull skin
• Itching — the most dominant symptom; often worse at night
• Rough patches that may be slightly discoloured

During flares:

• Intense itching — often described as unbearable; scratching provides temporary relief but worsens the skin
• Red, inflamed patches — the classic eczema rash. In darker skin tones (common in Indians), the rash may appear brown, grey, or purple rather than the red-on-white appearance typically depicted
• Dry, scaly patches
• Thickened, leathery skin from chronic scratching (lichenification)
• Small fluid-filled blisters that weep and crust in acute flares
• Cracked, fissured skin — painful, at risk of infection

Common locations in adults: the folds of the elbows, backs of the knees, wrists, ankles, neck, and around the eyes. In children: the face (particularly cheeks in infants) and the limbs.

Common Triggers in India

• Soaps and detergents: alkaline soaps with fragrances are among the most common triggers. Dish soap and laundry detergent without adequate rinsing from clothing are significant irritant exposures.
• Dust mites: one of the most common allergic triggers for eczema in India; dust mites thrive in mattresses, pillows, carpets, and soft furnishings
• Sweat: hot, humid Indian weather causes sweating that irritates eczema skin
• Wool and synthetic fabrics: rough textures irritate eczema skin; cotton is the recommended fabric
• Certain food allergens: in children particularly — eggs, cow's milk, wheat, soy, nuts are common. The link in adults is less clear and varies individually
• Stress: emotional stress reliably triggers or worsens flares in many patients
• Sudden temperature changes: moving between hot sun and cold AC, for example
• Fragranced products: perfumes, scented cosmetics, scented washing powder

Management: The Three-Part Approach

1. Consistent moisturising — the foundation of all eczema care

Restoring and maintaining the skin barrier with regular, generous moisturiser application is the most important ongoing management. Not just during flares — continuously.

The 'soak and seal' method: bathe in lukewarm water for 10–15 minutes (hydrates the outer skin layer), then immediately — within 3 minutes — apply a thick moisturiser to seal in the water.

Best moisturisers for eczema: those containing ceramides (skin barrier lipids), emollients, and occlusives. Ointments (most occlusive) > creams > lotions for eczema. Petroleum jelly (Vaseline) is inexpensive and highly effective for very dry eczema skin. Cetaphil cream, Vaseline Intensive Care, and similar barrier-repair formulations.

Apply twice daily minimum — morning after bathing and before bed.

2. Topical corticosteroids for flares

When a flare occurs, topical corticosteroids are the most effective treatment for reducing inflammation. Applied to the inflamed areas once or twice daily for 5–7 days.

Steroid selection:

• Mild (hydrocortisone 1%): for the face, neck, and skin folds
• Moderate (clobetasone butyrate, betamethasone valerate): for the body
• Strong (clobetasol propionate): for thick, lichenified skin; short-term use

Do NOT use strong steroids on the face. Do NOT use for extended periods without medical supervision — skin thinning and other side effects occur with prolonged use.

3. Identifying and avoiding triggers

Keeping a flare diary (noting when flares occur and what exposures preceded them) helps identify personal triggers. Common avoidances:

• Switch to fragrance-free, pH-neutral soap (syndet bars)
• Use fragrance-free laundry detergent, double-rinse clothing
• Wash new clothing before wearing
• Cover mattress and pillow with dust-mite proof covers; wash bedding weekly at 60°C
• Wear cotton clothing; avoid wool directly on skin
• Keep fingernails short to reduce skin damage from scratching

Other treatments

Topical calcineurin inhibitors (pimecrolimus, tacrolimus): prescription non-steroid alternatives for sensitive areas (face, skin folds) where steroid side effects are most concerning. Effective for maintenance and mild flares.

Antihistamines (cetirizine, loratadine): reduce itching, particularly at night. Sedating antihistamines (chlorpheniramine) at night help with sleep-disrupting itch.

Wet wrap therapy: for severe flares — moisturiser applied heavily, skin wrapped in damp bandages, then dry outer layer. Highly effective for children with severe eczema; requires physiotherapy guidance.

Dupilumab (Dupixent): a biologic injection (anti-IL-4/IL-13) for severe adult eczema not responding to other treatments. Highly effective; now available in India though expensive.

Phototherapy (UVB): for widespread moderate-severe eczema; multiple sessions at a dermatology clinic.

When to See a Doctor

• Eczema affecting sleep, work, or daily function despite moisturising
• Spreading, worsening, or not responding to mild steroid within 2 weeks
• Signs of infection (yellow crust, weeping, warm skin, fever) — bacterial infection of eczema skin is common and needs antibiotics
• Eczema affecting the face
• In children: eczema not responding to 2 weeks of appropriate management, or concerning their growth or sleep
