Eczema: A Complete Guide for International Patients in Shanghai

Introduction

Eczema — also known as atopic dermatitis — is one of the most common chronic skin conditions in the world, affecting people of all ages. For international patients and expatriates living in Shanghai, managing eczema can be particularly challenging due to the city's unique climate, air quality, and dietary environment. This guide is designed to help you understand eczema, recognize its symptoms, explore treatment options available in Shanghai, and know when to seek specialist care.

What Is Eczema?

Eczema is a chronic inflammatory skin condition characterized by dry, itchy, and inflamed skin. It is not contagious. The condition tends to flare periodically and then subside. While there is currently no cure, eczema is highly manageable with the right treatment plan and lifestyle adjustments.

Types of Eczema

There are several distinct types of eczema, each with its own triggers and presentation:

• Atopic Dermatitis: The most common form, often beginning in childhood and associated with asthma and hay fever. Characterized by intense itching and rash, typically in the creases of elbows and knees.
• Contact Dermatitis: Triggered by direct contact with an irritant (e.g., detergents, metals, cosmetics) or allergen. Causes localized redness, itching, and blistering.
• Dyshidrotic Eczema: Affects the hands and feet, producing small, intensely itchy blisters. Often worsened by stress and seasonal changes — both common in Shanghai.
• Seborrheic Dermatitis: Affects oily areas such as the scalp, face, and chest. Presents as scaly patches and dandruff.
• Nummular Eczema: Coin-shaped patches of irritated skin, often triggered by dry weather or skin injuries.

Symptoms & Warning Signs

Common symptoms of eczema include:

• Persistent itching, often worse at night
• Dry, sensitive skin
• Red to brownish-gray patches
• Small, raised bumps that may weep fluid when scratched
• Thickened, cracked, or scaly skin
• Raw, swollen skin from scratching

See a doctor promptly if: your symptoms are severe, you develop a skin infection (yellow crusting, warmth, pus), or over-the-counter treatments are not providing relief.

Note: Eczema can be mistaken for psoriasis, fungal infections, or contact rashes. A proper dermatological diagnosis is essential.

Causes & Triggers

Eczema results from a combination of genetic and environmental factors. Key triggers include:

• Genetics: A family history of eczema, asthma, or allergies significantly increases risk.
• Immune system dysfunction: An overactive immune response leads to skin inflammation.
• Environmental factors: Pollution, dust mites, pet dander, mold, and pollen.
• Shanghai-specific triggers: High humidity in summer, cold dry winters, seasonal air quality fluctuations (PM2.5), and dietary changes when relocating.
• Stress: A major and often underestimated trigger, particularly relevant for expats adjusting to a new environment.
• Irritants: Soaps, detergents, shampoos, disinfectants, and certain fabrics.

Diagnosis in Shanghai

Diagnosing eczema in Shanghai follows international standards. A dermatologist will typically:

• Review your personal and family medical history
• Conduct a thorough physical examination of the skin
• Order patch testing or allergy panels to identify specific triggers
• Rule out other skin conditions through clinical assessment or biopsy if needed

At Shanghai's top public hospitals, dermatology departments are well-equipped and staffed by highly trained specialists. However, navigating appointments, language barriers, and hospital systems can be challenging for international patients — this is where a medical concierge service becomes invaluable.

Treatment Options

Treatment is tailored to the severity of your condition and your individual triggers. Options available in Shanghai include:

Topical Treatments

• Corticosteroid creams and ointments: First-line treatment to reduce inflammation and itching. Available in varying strengths.
• Calcineurin inhibitors (tacrolimus, pimecrolimus): Non-steroidal options suitable for sensitive areas such as the face and skin folds.
• Crisaborole (Eucrisa): A newer non-steroidal anti-inflammatory ointment.

Systemic Medications

• Oral antihistamines: Help manage itching, particularly at night.
• Oral corticosteroids: Short-term use for severe flares.
• Immunosuppressants (cyclosporine, methotrexate): For moderate-to-severe cases not responding to topical treatments.

Biologics

• Dupilumab (Dupixent): A targeted biologic therapy approved for moderate-to-severe atopic dermatitis. Increasingly available in China and highly effective for eligible patients.

Phototherapy

Narrowband UVB light therapy is available at major Shanghai hospitals and can be effective for widespread eczema that does not respond to topical treatments.

Traditional Chinese Medicine (TCM)

Many Shanghai hospitals offer integrated TCM approaches alongside conventional treatment, including herbal medicine and acupuncture. Some patients find complementary benefit, though evidence varies. Always discuss TCM options with your dermatologist before starting.

Skincare & Daily Management

Consistent daily skincare is the cornerstone of eczema management:

• Moisturize daily: Apply a fragrance-free emollient immediately after bathing to lock in moisture. Look for ceramide-based products.
• Bathe wisely: Use lukewarm (not hot) water, limit baths to 10–15 minutes, and use gentle, fragrance-free cleansers.
• Choose skin-friendly fabrics: Wear soft, breathable cotton. Avoid wool and synthetic fabrics directly against the skin.
• Identify and avoid your triggers: Keep a symptom diary to track flares and correlate them with food, environment, or stress.
• Manage stress: Mindfulness, exercise, and adequate sleep all play a role in reducing flare frequency.

Eczema in Children

Eczema is particularly common in infants and young children. For expat families in Shanghai:

• Pediatric dermatologists at top Shanghai hospitals are experienced in managing childhood eczema.
• Communicate with your child's school or daycare about triggers and emergency protocols.
• Avoid over-bathing and use gentle, pediatric-formulated moisturizers.
• Many children see significant improvement or full remission as they grow older.

Living in Shanghai with Eczema

Practical tips for managing eczema day-to-day in Shanghai:

• Pharmacies: Major chains such as Guoda and Yifeng carry international brands (Cetaphil, La Roche-Posay, Eucerin) alongside domestic options. Prescription medications require a valid Chinese prescription.
• Air quality: Invest in a quality HEPA air purifier for your home, particularly during high-pollution days. Monitor the AQI daily.
• Humidity control: Use a humidifier in winter when indoor heating dries the air significantly.
• Hospital navigation: Top dermatology departments at hospitals such as Huashan Hospital and Ruijin Hospital are highly regarded. Booking specialist appointments and navigating the system in Chinese can be complex for international patients.
