Allergies are of various types, and it is essential first to identify and eliminate the allergen. Allergy immunotherapy can be given, or symptoms can be alleviated through allergy medications. It's crucial to target the treatment specifically, avoid re-exposure to allergens during treatment to prevent worsening of the condition. If there is an allergic reaction on the face, try to avoid using topical medications containing corticosteroid hormones. If the allergy is severe, it is recommended to seek investigation and management at a formal medical institution. In daily life, pay attention to diet and lifestyle, and avoid contact with allergenic foods.
