Contact Dermatitis – Overview
Contact dermatitis is a common inflammatory skin condition triggered by direct contact with an irritant or allergen. It results in red, itchy, and sometimes blistered or scaly skin. This can affect people of all ages and may appear on any part of the body, though it is most frequently seen on the hands, arms, face, and neck — areas most likely to come into contact with reactive substances.
The condition occurs when the skin’s natural protective barrier is disrupted by either a chemical irritant or an allergen. Irritant this is caused by substances that physically damage the skin, such as detergents, solvents, or acids. Allergic contact dermatitis, on the other hand, occurs when the immune system overreacts to a harmless substance like nickel, fragrances, or certain preservatives, leading to a delayed hypersensitivity reaction.

This can develop suddenly or gradually, depending on the intensity and frequency of exposure. Some people may develop symptoms after a single high-dose exposure, while others may become sensitised after repeated contact over time. Though not contagious or life-threatening, the condition can be extremely uncomfortable and affect quality of life, especially if it becomes chronic.
Prevention and management involve identifying and avoiding the offending agent, protecting the skin, and using topical treatments to reduce inflammation and itching. With appropriate care, most cases resolve completely within a few days to weeks.
In summary, this is an inflammatory skin reaction caused by exposure to irritants or allergens. Early identification and avoidance of triggers are key to successful treatment and preventing recurrence.
