What type of allergic reaction occurs from exposure to allergens or irritants?

1. Atopic dermatitis

2. Contact dermatitis

3. Urticaria

4. Angioedema

The correct answer is: Contact dermatitis

Contact dermatitis is a type of allergic reaction that occurs when the skin comes into direct contact with an allergen or irritant. This skin condition can be triggered by various substances such as certain chemicals, soaps, metals like nickel, and even plants like poison ivy. The reaction typically manifests as redness, itching, and swelling in the affected area, and may even develop into blisters in more severe cases. Understanding contact dermatitis is important for estheticians because they often work with various products and ingredients that could potentially cause reactions in clients. Recognizing this type of reaction allows for better product selection and advising clients on how to care for their skin, especially if they have known sensitivities. In contrast, atopic dermatitis is a chronic condition linked to genetic factors rather than specific contact with irritants. Urticaria, commonly known as hives, involves raised welts and can result from internal factors or systemic allergic reactions, while angioedema refers to deeper tissue swelling often related to severe allergic responses. Each of these conditions has distinct characteristics and triggers separate from contact dermatitis.
