What should I do if my child has an allergic reaction and develops bumps on their face?

It is common for children to develop rashes on their face due to allergies, which are usually related to food, environmental factors, or contact allergens. The following measures can be taken: 1. Avoid allergens: Observe and identify possible foods or environmental factors that may trigger allergies. Avoid known allergens and maintain a clean indoor environment to reduce allergens such as dust and pollen. 2. Use anti-allergy medications: Under a doctor's guidance, use appropriate anti-allergy medications, such as oral antihistamines or topical anti-allergy creams, to relieve skin symptoms and itching. 3. Keep the skin clean and moisturized: Use mild, non-irritating facial cleansers to clean the face, and avoid skincare products containing fragrances or alcohol. Keeping the skin moisturized can alleviate dryness and irritation. If the rash on the face persists or is accompanied by severe symptoms such as difficulty breathing or worsening swelling, seek medical attention immediately.
