What should I do if my facial skin is allergic, red, and itchy?

Facial skin allergies presenting as redness and itching may be caused by contact allergens, food allergies, climate changes, irritants in skincare products, and other factors. Below are some initial management steps and recommendations: 1. **Identify the allergen**: Carefully recall and identify substances that may have triggered the allergy, such as cosmetics, skincare products, foods, medications, pollen, or dust mites. 2. **Avoid exposure**: Once the allergen is identified, avoid further contact with it as much as possible to prevent recurrence of allergic symptoms. 3. **Skincare**: Use gentle cleansing products and avoid facial cleansers or toners containing irritating ingredients such as alcohol or fragrances. Use lukewarm water for washing your face, avoiding water that is too hot or too cold, which may irritate the skin. After washing, gently pat the skin dry rather than rubbing vigorously. 4. **Avoid irritation**: Refrain from scratching the face, as this may worsen allergy symptoms or lead to infection. Avoid prolonged exposure to strong sunlight; if going outdoors, take proper sun protection measures. 5. **Dietary adjustments**: Maintain a light diet and avoid consuming spicy, irritating, or greasy foods such as chili peppers, mustard, and coffee. Eat more fresh vegetables and fruits to obtain essential vitamins and minerals, which can help enhance the skin's resistance. If symptoms are severe or do not improve, seek professional medical assistance promptly.
