Eczema and Contact Dermatitis: Symptoms, Causes and Treatment

"Eczema" is the everyday word for almost any itchy, red, flaky or weeping rash. Medically, eczema (dermatitis) is not one disease but a group of inflammatory skin reactions. One of its most common members is contact dermatitis, which develops where the skin meets an external trigger. Treatment only works when we know which type of eczema we are dealing with, so every patient who comes to our practice with "eczema" is first assessed for type and trigger.

Types of eczema

• Atopic dermatitis: chronic eczema linked to an allergic constitution, usually starting in childhood, with dry, itchy skin. See our atopic dermatitis page.

• Contact dermatitis: eczema caused by a substance touching the skin — detergents, metals, cosmetics, dyes, latex, plants. It has two subtypes: irritant and allergic.

• Hand eczema: one of the most common adult forms, constantly re-triggered by hand washing, dishwashing, detergents and occupational exposure.

• Seborrhoeic dermatitis: flaky redness in oily areas (scalp, eyebrows, sides of the nose). See seborrhoeic dermatitis.

• Nummular (discoid) eczema, dyshidrotic eczema and stasis dermatitis are less common types.

Contact dermatitis: irritant or allergic?

Irritant contact dermatitis happens when the skin barrier is directly damaged by irritants — detergents, solvents, frequent water contact, soap. No allergy is involved and anyone exposed enough will develop it. Allergic contact dermatitis, by contrast, is an immune sensitisation to a specific substance — most often nickel, fragrances, preservatives, hair-dye ingredients and rubber chemicals — with an itchy, red, sometimes blistering rash appearing one to three days after contact. The two can look alike; they are told apart by the history and, where needed, patch testing.

Symptoms

• Itch, usually the most distressing symptom

• Redness, swelling and, in the acute phase, tiny blisters and oozing

• Thickened, cracked and scaly skin once the eczema becomes chronic

• A rash confined to the contact area — nickel under a necklace, gloves on the backs of the hands, an earring on the earlobe

Diagnosis: who needs a patch test?

Most eczema is diagnosed by examination. But when eczema keeps coming back, never fully clears, sits on the hands, face or eyelids, or is work-related, identifying the allergen changes the treatment completely. In patch testing, suspected substances are applied to the back in small patches and the skin reaction is read after 48–96 hours. Blood IgE allergy panels do not detect contact allergens — the two tests are often confused.

How treatment is planned

• Avoiding the trigger: removing the identified allergen or irritant from daily life is the foundation; patients receive a written list of products to avoid.

• Barrier repair: moisturisers and barrier creams several times a day, especially after water contact; soap-free cleansers instead of soap.

• Topical corticosteroids: for flares, at the right strength and duration. Used correctly they are safe; uncontrolled long-term use thins the skin.

• Calcineurin inhibitors and newer topical molecules: for sensitive sites such as the face, eyelids and folds, and for long-term control.

• Phototherapy, systemic drugs and JAK inhibitors: for widespread, resistant or life-limiting disease, under dermatologist supervision.

• Treating infection: scratched eczema often becomes infected; yellow crusting may need antibiotics.

Frequently asked questions

Is eczema contagious? No. No type of eczema passes from person to person.

Are steroid creams harmful? Topical steroids used at the strength, duration and site set by a dermatologist are the best-evidenced step in eczema treatment. Harm comes from uncontrolled, prolonged use.

Does hand eczema ever clear completely? Full clearance is hard while the trigger continues; with protective gloves, barrier care and the right treatment most patients achieve long-term control.
