Skin Allergies

Q: What is the difference between a skin allergy and sensitive skin?

Sensitive skin reacts to many products without involving the immune system. A skin allergy is a specific immune response to a particular substance. Allergy testing can distinguish between the two.

Q: Can I develop an allergy to something I have used for years?

Yes. Allergies can develop at any time, even to substances you have used for years without issues. This is called delayed-type hypersensitivity.

Q: Can skin allergies be cured?

There is no cure, but allergies can be managed effectively. Avoiding triggers and using appropriate treatment allows most people to live comfortably.

What Are Skin Allergies?

A skin allergy occurs when the immune system overreacts to a normally harmless substance (allergen), causing inflammation, redness, itching, and rashes. Skin allergies can be triggered by direct contact with an allergen (contact dermatitis), ingestion of food or medication, or inhalation of airborne allergens.

Common types of skin allergies include allergic contact dermatitis (from touching allergens like nickel, fragrances, or latex), atopic dermatitis (eczema triggered by allergens), and urticaria (hives). Identifying the specific trigger is essential for effective management.

Common Symptoms

Red, itchy rash: Appears at the site of contact with the allergen.
Bumps or blisters: Small, fluid-filled bumps that may ooze and crust.
Swelling: Localised swelling around the affected area.
Dry, cracked, scaly skin: Especially with repeated exposure.
Burning or stinging: The skin may feel warm or tender.
Delayed reaction: Contact allergy symptoms often appear 24 to 48 hours after exposure.

How Skin Allergies Are Diagnosed

Your doctor will take a detailed history of your symptoms, including when they started, what products or substances you were exposed to, and any patterns you have noticed. Patch testing is the gold standard for diagnosing contact allergies. Small patches containing common allergens are applied to your back and left for 48 hours. The doctor checks your skin for reactions at 48 and 96 hours. This helps identify exactly which substances trigger your allergy.

Skin Allergy Treatment Options

Treatment focuses on relieving symptoms and avoiding triggers:

Avoidance: Once identified, avoid the offending allergen or irritant. This is the most effective long-term strategy.
Topical corticosteroids: Prescription creams to reduce inflammation and itching during flare-ups.
Oral antihistamines: Help control itching and allergic reactions.
Moisturisers: Fragrance-free, hypoallergenic moisturisers to repair the skin barrier.
Skincare routine: Gentle cleansing and moisturising with products suitable for sensitive skin.
Management plan: Step-by-step guidance on handling flare-ups when they occur.

Lifestyle & Home Care for Skin Allergies

Read product labels: Avoid known allergens in skincare, cosmetics, and household products. Look for fragrance-free, hypoallergenic labels.
Patch test new products: Apply a small amount of a new product to your inner arm for a few days before using it on your face or body.
Gentle skincare: Use mild, fragrance-free cleansers and moisturisers. Avoid harsh exfoliants and alcohol-based products.
Protect your hands: Wear gloves when handling cleaning products, chemicals, or known irritants.
Cool compresses: Apply a cool, damp cloth to soothe itchy or inflamed skin.
Avoid scratching: Scratching worsens inflammation and can lead to infection. Keep nails short.
