### What is Contact Dermatitis? Contact dermatitis is a skin reaction that occurs when you touch a certain substance. It can be red, itchy, and uncomfortable but is not life-threatening. There are two main types: allergic contact dermatitis and irritant contact dermatitis. ### Causes - **Allergic Contact Dermatitis**: This happens when your immune system reacts to a substance as if it's under attack. Common triggers include poison ivy, nickel, and certain cosmetics. - **Irritant Contact Dermatitis**: This occurs when a substance damages the protective layer of your skin. Common irritants include detergents, soaps, and prolonged exposure to water. ### Symptoms - Redness - Itching - Dry, cracked, or scaly skin - Bumps or blisters (rare) - Swelling - Burning sensation - Tenderness ### Specific Areas - **Hands**: Can be affected by both types, especially in dry winter months or with frequent hand washing. - **Lips**: May crack and peel due to an allergic reaction. - **Feet**: Can react to materials in socks or shoes. ### Treatment - **Home Remedies**: Avoid scratching, use moisturizers, and wash off irritants immediately. - **Medical Treatments**: Steroid creams or ointments prescribed by a doctor. In severe cases, oral medications may be necessary. ### Prevention - Identify and avoid triggers. - Use protective gloves or barrier creams if you can't avoid contact with irritants. - Wash off allergens or irritants as soon as possible. ### When to See a Doctor - If the rash is severe, persistent, or spreading. - If you develop blisters or signs of infection.
