### Types of Skin Allergies Skin allergies occur when your immune system reacts to a substance that is usually harmless to most people. Here are some common types: 1. **Eczema (Atopic Dermatitis)**: This is a chronic condition that causes itchy, inflamed skin. It often appears in childhood and can be triggered by allergens like pollen or pet dander. 2. **Contact Dermatitis**: This occurs when your skin comes into direct contact with an allergen or irritant, leading to redness, itching, and sometimes blisters. Common triggers include soaps, cosmetics, and certain metals like nickel. 3. **Hives (Urticaria)**: These are red, itchy welts that can appear anywhere on the body. They can be triggered by foods, medications, or insect stings. 4. **Angioedema**: This is similar to hives but affects deeper layers of the skin, causing swelling, especially around the eyes and lips. It can be triggered by the same allergens that cause hives. ### Symptoms Common symptoms of skin allergies include: - Redness - Itching - Swelling - Blisters or hives - Dry, cracked skin ### Treatments Treatment options vary depending on the type and severity of the allergy: 1. **Avoiding Triggers**: The best way to manage skin allergies is to avoid the allergens that cause them. 2. **Topical Steroids**: These creams or ointments can reduce inflammation and itching. They are commonly used for eczema and contact dermatitis. 3. **Antihistamines**: These medications can help relieve itching and reduce hives. They are available over-the-counter and by prescription. 4. **Moisturizers**: Keeping your skin hydrated can help manage eczema and prevent flare-ups. 5. **Immunotherapy**: For severe allergies, your doctor may recommend allergy shots to gradually desensitize your immune system to the allergen. 6. **Emergency Epinephrine**: For severe allergic reactions like anaphylaxis, an epinephrine auto-injector can be life-saving. ### Prevention To reduce the risk of skin allergies: - Use hypoallergenic products - Wear protective clothing - Keep your skin moisturized - Avoid known allergens
