Contact allergies

Allergic contact dermatitis is an immune system response from allergy of a substance that makes the skin dry, itchy and irritated. It can be caused by a variety of toxic or non toxic substances such as antibiotics, metals, rubber, lotions and dyes.

Mild reactions are often treated with antihistamine medication, corticosteroids or soothing lotions and infections are usually treated with antibiotics.

Protein contact dermatitis is an allergic skin reaction induced principally by proteins of either animal or plant origin such as food, tree or plant products. PCD is caused by contact with the proteins in plant, animal, flour, and proteolytic enzymes and is often diagnosed in patients that have an occupation or hobby involving exposure to one of these protein allergens.

In protein contact dermatitis, avoidance of the particular allergen is of primary importance. Antihistamines, corticosteroids or immunomodulatory agents can be used to relieve symptoms, depending on the severity.

A cosmetic allergy is a reaction to cosmetic or beauty products which can cause contact dermatitis. Mild to severe symptoms include hives, rashes, flaking or peeling skin, facial swelling or anaphylaxis.

Cosmetic products used to beautify, cleanse or protect the hair, skin, teeth or complexion can cause cosmetic allergies. Common examples include fragrances, make-up, moisturisers, shampoos and para-phenylenediamine found in hair dye.

Products with fewer ingredients or hypoallergenic products may decrease the chance of a reaction. Creams and ointments containing mild topical steroids, such as hydrocortisone cream, may be used to help control itching, swelling, and redness.
