Which skin condition is often associated with allergic reactions?

1. Acne

2. Contact dermatitis

3. Rosacea

4. Hyperpigmentation

The correct answer is: Contact dermatitis

Contact dermatitis is a skin condition that arises primarily from an allergic reaction to substances that come into contact with the skin. This can include various allergens such as fragrances, preservatives, or metals like nickel. The condition manifests through symptoms such as redness, itching, swelling, and sometimes blisters, as the immune system reacts to these foreign substances. In contrast, acne is primarily related to clogged pores and hormonal changes, rosacea is characterized by facial redness and flushing often triggered by environmental factors rather than allergens, and hyperpigmentation involves dark patches on the skin typically caused by sun exposure or inflammation rather than direct allergic responses. Understanding the distinctive causes and symptoms of these conditions helps to clarify why contact dermatitis is specifically linked to allergies.
