Allergic reactions occur when the immune system overreacts to a typically harmless substance, known as an allergen. These reactions can manifest on the skin, causing irritation, inflammation, and discomfort. Dermatologists specialize in identifying triggers and managing symptoms effectively.
Common Causes of Skin Allergies :
1. Contact Allergens:
Examples: Nickel, cosmetics, fragrances, or latex.
Reaction: Contact dermatitis—red, itchy, or blistered skin at the point of contact.
2. Environmental Allergens:
Examples: Pollen, dust mites, or animal dander.
Reaction: Hives (urticaria) or generalized itching.
3. Food or Drug Allergies:
Examples: Peanuts, shellfish, certain medications.
Reaction: Rash, hives, or, in severe cases, anaphylaxis (a life-threatening condition).
4. Insect Bites or Stings:
Examples: Bee stings, mosquito bites.
