Contact Dermatitis – Consultant Dermatology Diagnosis & Treatment in London
Contact dermatitis is a common skin reaction caused by exposure to irritants or allergens, resulting in redness, itching, and discomfort. While often short-lived, it can become chronic without treatment. At Skinhorizon, we provide expert diagnosis and tailored care to relieve symptoms and prevent recurrences.
What is contact dermatitis?
Contact dermatitis is an inflammatory skin reaction that occurs when the skin comes into direct contact with substances that either irritate the skin or trigger an allergic response. It is one of the most frequent dermatological complaints and can affect anyone, from infants to older adults. While not life-threatening, the condition can significantly disrupt daily life by causing itching, burning, and visible rashes.
Contact Dermatitis Causes and triggers
There are two main types of contact dermatitis:
- Irritant contact dermatitis: Caused by direct damage to the skin barrier from substances like soaps, detergents, solvents, or acids. This is the most common type.
- Allergic contact dermatitis: Triggered when the immune system reacts to an allergen, such as nickel, fragrances, preservatives, or latex.
Risk factors include frequent handwashing, occupational exposure (e.g., healthcare, cleaning, hairdressing), use of harsh products, or genetic predisposition such as eczema.
Who is affected by Contact Dermatitis?
Contact dermatitis can occur at any age, but those who work with chemicals, wet environments, or allergens are more likely to develop it. Individuals with sensitive skin or a personal history of atopic eczema also face a higher risk.
Contact Dermatitis Symptoms and signs
The condition usually appears on exposed areas such as the hands, face, or arms. Common symptoms include:
- Red, itchy patches.
- Dry, cracked, or scaly skin.
- Burning or stinging sensations.
- Blisters that may ooze and crust in severe cases.
- Thickening of skin with chronic exposure.
Contact Dermatitis Diagnosis
Diagnosis is typically made by a dermatologist based on history and examination. For allergic types, patch testing can help identify the specific trigger. Identifying whether the dermatitis is irritant or allergic is essential for targeted management.

Management focuses on reducing symptoms, repairing the skin barrier, and preventing recurrences. Treatments include:
- Avoidance: Identifying and eliminating contact with irritants/allergens.
- Topical corticosteroids: To reduce inflammation and itching.
- Emollients: To repair the skin barrier and reduce dryness.
- Oral antihistamines: For relief of severe itching.
- Advanced therapies: Phototherapy or systemic treatments in resistant cases.
At Skinhorizon, we provide customised plans including patch testing and medical-grade skincare to manage both acute and chronic cases effectively.
Prevention and aftercare
Preventive measures are crucial. These may include:
- Wearing protective gloves in occupational settings.
- Using fragrance-free, hypoallergenic skincare products.
- Moisturising regularly to strengthen the skin barrier.
- Avoiding prolonged wet work without protection.
- Regular check-ups for individuals with recurrent dermatitis.
Special considerations
In skin of colour, dermatitis may present with dark brown or grey discolouration instead of redness. Chronic cases can lead to lichenification (skin thickening) and hyperpigmentation, which may require tailored treatment approaches.

What is the difference between irritant and allergic contact dermatitis?
Irritant dermatitis results from direct damage to the skin barrier, while allergic dermatitis is due to an immune response to a specific substance.
How long does it take for contact dermatitis to clear?
With proper treatment and avoidance, symptoms often improve within 2–4 weeks. Chronic cases may take longer.
Can contact dermatitis be cured permanently?
While there is no permanent cure, identifying and avoiding triggers can prevent recurrences. Treatment controls flare-ups effectively.
Is contact dermatitis contagious?
No, it is not contagious and cannot spread from person to person.
Should I see a dermatologist for contact dermatitis?
Yes, especially if the rash is persistent, severe, or recurrent. A dermatologist can perform patch testing and prescribe targeted treatment.
