This condition often arises as a result of direct skin exposure to irritants or allergens, leading to inflammation and irritation. Topical corticosteroids are effective because they reduce inflammation, swelling, and redness associated with this type of dermal response, promoting faster healing and symptom relief.

Topical corticosteroids work by inhibiting inflammatory mediators and decreasing vascular permeability, which helps to mitigate the symptoms of itchiness and discomfort associated with contact dermatitis. The potency of the steroid can be tailored to the severity of the condition, allowing for effective management of both acute and chronic cases.

While the other conditions listed can also utilize corticosteroids in management, they may not be treated primarily or exclusively with this therapy. For instance, zoster (shingles) typically requires antiviral medication to address the viral infection and may utilize corticosteroids to reduce inflammation, but they are not the first-line treatment.
