What Are The Types Of Contact Dermatitis?

There are primarily 2 main contact dermatitis types:

1. Irritant Contact Dermatitis: This type of dermatitis occurs due to direct contact with irritant substances, leading to skin inflammation. It does not involve an allergic reaction but is caused by the irritating properties of the substance.
2. Allergic Contact Dermatitis: Allergic contact dermatitis results from an exposure to allergens, triggering an immune response known as type 4 hypersensitivity reaction. It manifests as skin inflammation due to the immune system's reaction to the allergen.

What Causes Contact Dermatitis?

Contact dermatitis can be caused by various irritants and allergens.

Some common contact dermatitis causes include:

1. Irritants: Substances like soaps, detergents, solvents, acids, and alkalis can directly irritate the skin, leading to irritant contact dermatitis.
2. Allergens: Allergic contact dermatitis can be caused by exposure to allergens such as nickel (found in jewellery), fragrances, preservatives, rubber, and certain plants like poison ivy or poison oak.
3. Chemicals: Chemical compounds present in cosmetics, hair dyes, latex gloves, and topical medications can promote contact dermatitis.
4. Metals: Metals like nickel, chromium, and cobalt commonly found in jewellery, metal tools, and belt buckles can cause allergic reactions leading to contact dermatitis.
5. Plants: Certain plants like poison ivy, poison oak, and poison sumac contain oils that can cause allergic contact dermatitis upon skin contact.

What Are The Symptoms Of Contact Dermatitis?

Contact dermatitis presents with various symptoms, including:

1. Pruritus: Itching is a common symptom which is associated with contact dermatitis.
2. Erythema: The affected skin appears red due to contact dermatitis inflammation.
