What is eczema?
Eczema, or atopic dermatitis, is an inflammatory skin condition in which a weakened skin barrier lets moisture out and irritants in, producing dry, red, intensely itchy patches that flare and subside. It affects around one in five children — often starting in infancy, and frequently improving with age — and roughly one in ten adults, commonly alongside asthma and hay fever. Triggers vary from soaps, fabrics and heat to stress and allergens, and the relentless itch can disrupt sleep, school and work far more than outsiders appreciate.
Diagnosis is clinical, based on the appearance and pattern of the rash and personal or family history of atopy; allergy testing is occasionally useful, and severe or atypical cases warrant dermatology referral to access stronger treatments.
Common symptoms
- Dry, rough, itchy skin
- Red, inflamed patches, often in elbow and knee creases
- Intense itching, worse at night
- Cracked, weeping or crusted skin during flares
- Thickened, leathery skin from long-term scratching
- Disturbed sleep from itching
How long will you wait?
Most eczema is managed in primary care, but routine NHS dermatology referral for severe or uncontrolled eczema commonly takes four to seven months, with further waits for phototherapy or specialist drug clinics after that first appointment.
Privately, you can typically see a consultant dermatologist within 3–7 days, with a full treatment plan started at the first visit and specialist therapies under way within 2–4 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- Emollients. Generous, daily moisturising is the foundation of all eczema care, repairing the skin barrier and preventing flares.
- Topical steroids. Steroid creams and ointments of appropriate strength settle flares quickly and are safe when used as directed.
- Topical calcineurin inhibitors. Steroid-free creams such as tacrolimus suit delicate areas like the face and eyelids and long-term maintenance.
- Phototherapy. Hospital-supervised courses of UVB light treatment help widespread eczema resistant to creams.
- Systemic and biologic treatment. Tablets or injections such as methotrexate, dupilumab or JAK inhibitors transform severe eczema under specialist care.
What does private treatment cost?
As a guide, a private dermatology consultation costs around £200–£300, with follow-ups £150–£250; a private phototherapy course typically costs £800–£1,500, while ongoing biologic drugs run to four figures annually if self-funded.
Does health insurance cover eczema?
Eczema illustrates the acute-versus-chronic distinction at the heart of private medical insurance. Policies will typically cover specialist consultations and treatment for a significant new flare or diagnostic uncertainty, but eczema is a chronic condition, so ongoing routine management — repeat prescriptions, maintenance appointments, long-term biologic therapy — usually reverts to the NHS or self-pay. Eczema you had before taking out the policy is normally excluded as pre-existing.
Frequently asked questions
Are steroid creams safe for long-term eczema?
Used correctly, yes — decades of experience support them, and undertreating eczema causes more harm than appropriate steroid use. Problems such as skin thinning arise mainly from prolonged, continuous use of potent steroids on thin-skinned areas like the face. The safe pattern is treating flares promptly with the right strength for the right body site, then stepping down to emollients and, where needed, steroid-free maintenance creams. Your prescriber should explain amounts using fingertip units.
Will my child grow out of eczema?
There is a good chance. Most children who develop eczema in infancy see substantial improvement through childhood, and many are largely clear by their teens. A proportion continue with eczema into adulthood or see it return later — often triggered by irritant jobs, stress or environment — and children with severe eczema, or accompanying asthma and food allergies, are more likely to have persistent disease. Consistent skincare habits established early pay off either way.
Is eczema caused by an allergy I could test for?
Usually not in the way people hope. Eczema is primarily a skin barrier and immune condition, not a hidden allergy, and blanket allergy testing rarely reveals a single fixable cause. Specific triggers do matter for some: certain foods in young children with severe eczema, house dust mite, or contact allergens such as fragrances and nickel. A dermatologist can judge whether targeted testing is worthwhile.
