5 Surprising Triggers of Skin Allergies You Never Knew Existed

What is a Skin Allergies?

Skin allergy means that skin becomes irritated because the immune system goes into action against something that normally is inoffensive. This is an allergic reaction. Allergic reaction is manifested by rash, itching, burning and redness of the skin. There will also be bumps or hives with swelling (in severe cases).

Common Types of Skin Allergies

1. Atopic Dermatitis (Eczema)

Atopic dermatitis, commonly known as eczema, presents as easily irritated, itchy, and dry skin. It’s prevalent in children, often related to genetic and environmental factors, and can be associated with asthma, food, and seasonal allergies. Triggers like specific foods, stress, certain soaps, lotions, and environmental conditions can exacerbate eczema symptoms.

2. Allergic Contact Dermatitis

Allergic contact dermatitis occurs when the skin encounters a substance triggering a reaction. For instance, contact with nickel in jewelry or exposure to poison ivy oil can prompt allergic responses.

3. Urticaria (Hives)

Urticaria appears as raised itchy bumps on the skin due to allergens, such as certain foods or bug bites, triggering the release of histamine in the body.

4. Angioedema

Angioedema involves deep swelling in the skin, commonly occurring in areas like eyelids, lips, and throat, often concurrent with hives.

Identifying and Managing Symptoms

The symptoms of these skin allergies vary:

  • Eczema: Presents as an itchy, scaly, red, and dry rash, often observed on the face, hands, elbows, and knees, sometimes accompanied by fluid discharge.
  • Allergic Contact Dermatitis: Induces a rash, sometimes itchy and often painful, with raised bumps and blisters, occurring immediately or up to 48 hours after exposure to the triggering substance.
  • Hives: Manifests as raised, flat, itchy bumps, occasionally tender, signaling a potentially serious allergic reaction.
  • Angioedema: Causes deep-seated swelling, particularly around eyelids, lips, or throat, warranting urgent medical attention if accompanied by breathing difficulties or widespread hives.

Seeking Medical Attention

Immediate medical attention (911 or ER) is crucial when:

  • Hives cover the entire body
  • Breathing difficulties arise

Consult a doctor if:

  • Assistance is needed to manage eczema symptoms
  • Rashes show signs of infection or fail to improve after 2-3 weeks
  • Suspected development of new allergies

Diagnosis Methods

To diagnose skin allergies, doctors may:

  • Conduct inquiries about skin conditions, symptoms, and triggering factors.
  • Perform physical examinations, assessing potential allergic signs in eyes, nose, throat, and chest.
  • Recommend various allergy tests:

Skin Allergies Testing Methods

  • Skin Prick Test: Involves exposing the skin to suspected allergens, observing immediate reactions like rashes, redness, or itching.
  • Intradermal Skin Test: Utilized if initial skin prick test results are inconclusive, involves injecting allergens under the skin.
  • Blood Tests (specific IgE): Analyze blood samples for IgE reactions to suspected allergens, though they may occasionally yield false positives.
  • Challenge Test: Administering minute amounts of allergens under supervision to observe potential reactions.
  • Patch Test: Identifying allergic contact dermatitis by applying allergens to the skin under a bandage for a few days.

Treatment Approaches

Managing skin allergies involves two primary approaches:

  • Avoidance: Identifying and steering clear of known allergens.
  • Medication and Therapeutic Strategies: Utilizing creams, medications, and other remedies to alleviate itching, swelling, or pain.

Tailored Treatment for Different Allergic Skin Reactions


  • Avoid skin abrasion or excessive scratching.
  • Regularly moisturize with alcohol, fragrance, and dye-free lotions or ointments after bathing.
  • Avoid wool and lanolin-based products.
  • Use mild soaps and take lukewarm, shorter baths or showers.

Hives and Angioedema:

  • Acute cases: Employ antihistamines like Benadryl® and avoid known triggers. Consider carrying an EpiPen for severe reactions.
  • Chronic cases: Identify triggers (e.g., alcohol, aspirin), keep skin cool, and wear loose-fitting clothing. Antihistamines are common treatment options.

Allergic Contact Dermatitis:

  • Skin reactions usually resolve in 14-28 days.
  • Immediately wash the skin if exposed to allergens like poison ivy.
  • Doctors may prescribe antihistamines or cortisone medications to aid in healing.
  • Calamine lotion, cool compresses, or oatmeal baths can relieve itching and discomfort.

Preventive Measures

  • Identify and avoid potential allergens in direct contact with the skin, including soaps, hair products, makeup, lotions, and deodorants.
  • Food and medications can also trigger allergic reactions, particularly hives and swelling.


Understanding skin allergies involves recognizing their diverse manifestations, seeking appropriate medical attention, and adopting preventive measures. Timely diagnosis and tailored management strategies significantly alleviate symptoms and enhance quality of life for individuals affected by these conditions.
