Atopic Dermatitis (Eczema)

Medically reviewed by Joel Nyandigira Updated August 2026

Overview


Atopic dermatitis, commonly known as eczema, is a chronic inflammatory skin condition causing dry, itchy, inflamed patches of skin. It often begins in childhood and is linked to other allergic conditions such as asthma and hay fever.

Symptoms of Atopic Dermatitis (Eczema)


  • Dry, itchy skin, which can be intense, especially at night
  • Red to brownish-grey patches, commonly on the hands, feet, ankles, wrists, neck, and the creases of the elbows and knees
  • Small, raised bumps that may leak fluid and crust over when scratched
  • Thickened, cracked, or scaly skin with long-standing or repeated scratching
  • Symptoms typically flare periodically, with calmer periods in between

What Causes Atopic Dermatitis (Eczema)?


  • Results from a combination of genetic factors affecting the skin barrier and immune system, along with environmental triggers.
  • Common triggers include dry skin, irritants (such as soaps or certain fabrics), allergens (such as dust mites or pet dander), stress, sweating, and temperature changes.
  • Often occurs alongside other allergic conditions, such as asthma and allergic rhinitis, and tends to run in families.

How is Atopic Dermatitis (Eczema) Diagnosed?


  • Diagnosed clinically based on the characteristic appearance, distribution, and chronic, relapsing pattern of the rash, together with a personal or family history of allergic conditions.
  • Specific allergy testing is not usually needed for typical cases but may be considered if a particular trigger is strongly suspected and not obvious from history.

Treatment for Atopic Dermatitis (Eczema)


Regular use of a fragrance-free moisturiser, applied generously and frequently, is a cornerstone of management and helps repair and protect the skin barrier.

A topical corticosteroid cream or ointment is used during flares to reduce inflammation and itching, applied for a limited course as directed and then stopped or reduced once the flare settles.

Identifying and avoiding personal triggers — such as certain soaps, fabrics, or known allergens — helps reduce the frequency of flares.

For more persistent or severe eczema not controlled by these measures, additional treatments such as other topical anti-inflammatory medicines or, in more severe cases, systemic treatment may be considered by a specialist.

Keeping fingernails short and addressing itching promptly helps reduce skin damage and secondary infection from scratching.

How to Prevent Atopic Dermatitis (Eczema)


  • Moisturise the skin regularly, especially after bathing, using a fragrance-free product.
  • Use lukewarm rather than hot water for bathing, and pat skin dry rather than rubbing.
  • Identify and avoid personal triggers, such as certain soaps, fabrics, or known allergens.
  • Manage stress, as it can trigger or worsen flares in some people.
  • Keep the home environment free of excessive dust where possible, particularly if dust mites are a known trigger.
