What should I do if my face is red and itchy due to an allergic reaction?

When facing facial allergy and redness, the first step is to identify the allergen, which may include food, medications, cosmetics, or environmental factors. Once a potential allergen is identified, exposure should be immediately discontinued, followed by the following treatments:

1. Gentle cleansing: Use mild, soap-free facial cleansers and avoid vigorously rubbing the face to reduce physical irritation.

2. Avoidance of irritants: Avoid skincare products containing alcohol, fragrances, or other irritating ingredients to prevent worsening of symptoms.

3. Cold compress: Wrap cold water or an ice pack in a towel and gently apply it to the swollen area to help alleviate inflammation and itching.

4. Moisturizing: Choose fragrance-free, non-irritating moisturizers or gels to help repair the skin barrier and reduce water loss.

5. Medications: Antihistamine medications such as Levocetirizine Dihydrochloride Tablets or Desloratadine Tablets may be taken orally under medical supervision to effectively relieve symptoms. For topical treatment, initially apply boric acid solution as a cold compress to reduce redness and itching, followed by topical application of medications such as Boric Acid, Zinc Oxide, and Borneol Ointment or Tacrolimus Ointment.

If the above measures are ineffective or if severe symptoms occur (such as difficulty breathing or swelling), prompt medical attention is necessary. Consult a dermatologist for professional advice, as topical corticosteroids or other treatment methods may be required.
