What should I do if my face itches due to an allergy to willow catkins?

When facial itching is caused by an allergy to willow catkins, the following measures can help alleviate symptoms: 1. **Avoid the allergen**: Leave areas where willow catkins are dispersing, reduce contact with the catkins, and wear protective gear such as masks and goggles when outdoors to prevent direct contact with facial skin. 2. **Keep the face clean**: Use a gentle facial cleanser to wash the face and remove any residual catkins. Avoid skincare products containing alcohol or irritating ingredients, as they may worsen the allergic reaction. 3. **Cold compress**: Apply a cold compress using chilled water or a refrigerated towel to the affected area to help relieve itching and reduce swelling. 4. **Medication**: If itching is severe, take antihistamine medications such as loratadine or cetirizine under a doctor's guidance. Topical treatments such as mometasone furoate cream or calamine lotion may also be used to alleviate symptoms. 5. **Sun protection**: During an allergic reaction, the skin is more sensitive and prone to UV damage. Therefore, it is essential to take proper sun protection measures when outdoors. If symptoms persist or worsen, seek medical attention promptly.
