Skin allergies are hypersensitivity reactions that occur on the skin. They typically arise from contact with allergens and can manifest with symptoms such as redness, itching, swelling, and rashes. Common allergens include pollen, dust mites, pet dander, certain foods, and chemical substances. Skin allergies can present in different forms, such as atopic dermatitis, contact dermatitis, and urticaria. Treatment options include antihistamines, corticosteroid creams, and avoidance of allergens. Identifying the factors that trigger allergies and implementing appropriate treatment methods is essential for maintaining skin health.
