Which condition is characterized by itchy, red, and inflamed skin often linked to allergies?

The condition defined by itchy, red, and inflamed skin commonly associated with allergies is contact dermatitis. This skin reaction occurs when the skin comes into contact with a substance that provokes an allergic response or irritates the skin. Common allergens can include certain metals in jewelry, fragrances in personal care products, or chemicals in cleaning products. In contact dermatitis, the symptoms typically manifest at the site of exposure, resulting in localized redness, swelling, and discomfort.

In contrast to other options, urticaria, also known as hives, presents with raised, itchy welts on the skin but is more often linked to systemic allergic reactions rather than direct contact with an irritant. Psoriasis is a chronic autoimmune condition characterized by thick, scaly patches on the skin that are usually not directly linked to allergies—rather, they are associated with genetic and immune factors. Angioedema involves deeper layers of the skin and mucous membranes, often resulting in swelling around the eyes and lips, but it is not mainly characterized by red, inflamed skin in response to allergens. Thus, contact dermatitis is the most fitting answer for the symptoms described.
