Skin Allergies

How Allergies Affect the Skin

An allergy occurs when the body has a hypersensitive immune response to a particular substance. Triggers can be airborne (pollen, dust), ingested (foods, medications), touched (metals, fragrances, plants), or injected (insect stings, drugs). When this happens, the body overproduces antibodies, causing skin reactions such as rashes, hives (urticaria), blisters, swelling, and itching.

For many people, allergies are seasonal. For others, symptoms persist year-round depending on the trigger. In either case, a dermatologist can help identify the cause and develop an effective management plan.

Common Allergic Skin Conditions

Contact dermatitis occurs when the skin reacts to direct contact with an allergen or irritant, such as nickel, fragrances, latex, or certain plants like poison ivy. It typically presents as a red, itchy rash at the site of contact.

Hives (urticaria) are raised, itchy welts that can appear anywhere on the body and may be triggered by foods, medications, insect stings, or environmental factors. Eczema (atopic dermatitis) is a chronic inflammatory condition that causes dry, itchy, inflamed skin and is often linked to allergies and immune system sensitivity.

Diagnosis and Treatment

Our dermatologists evaluate your symptoms, medical history, and potential triggers to determine the cause of your allergic skin reaction. Patch testing may be recommended to identify specific contact allergens. Treatment options include topical medications, oral antihistamines, prescription creams, and strategies to avoid known triggers and reduce future flare-ups.
