Which skin condition is triggered by a chemical or substance and leads to redness and vesicles that ooze?

Contact dermatitis is a skin condition that occurs when the skin comes into direct contact with an irritant or allergen, causing an inflammatory reaction. This condition is characterized by redness and the development of vesicles, which are small fluid-filled blisters that often ooze when they rupture. The irritation leads to a localized inflammatory response, manifesting as itching, swelling, and discomfort in the affected area.

In contrast, urticaria, also known as hives, is primarily characterized by raised, itchy welts on the skin due to an allergic response but does not typically involve vesicles that ooze. Atopic dermatitis, or eczema, is a chronic condition related to inflammation and dry skin that may also have vesicles but is not predominantly triggered by direct contact with a substance. Psoriasis is an autoimmune condition that typically presents as red, scaly patches and does not involve vesicular eruptions nor is it primarily induced by contact with irritants or allergens. Therefore, the features of contact dermatitis align perfectly with the symptoms described in the question.
