Cause 2. Contact Dermatitis: Skin’s Direct Protest
Contact dermatitis is an eczema type that occurs as a direct response to the skin’s contact with certain substances. This type is split into two categories: allergic contact dermatitis and irritant contact dermatitis. Both types manifest with similar symptoms, making them difficult to distinguish without medical assistance.
Allergic contact dermatitis results from an allergic reaction to a particular substance. Common culprits include nickel, fragrances, and poison ivy. The reaction can occur hours or even days after exposure, causing a red, itchy rash where the skin touched the allergen.
Irritant contact dermatitis, on the other hand, is not an allergic reaction but a direct irritation of the skin. This irritation often occurs from frequent or prolonged exposure to harmful substances like detergents, solvents, or even water. The skin’s response is typically immediate, resulting in redness, itching, and possible blistering.
Occupation can play a significant role in the development of contact dermatitis. Those in professions requiring frequent hand washing or exposure to chemicals, like healthcare workers or cleaners, are at increased risk. Therefore, preventive measures such as using gloves, frequent moisturizing, and using milder soaps can help manage and prevent this type of eczema. (2)
