What should I do if my skin itches due to sun allergy?

When skin itchiness is caused by sun allergy, the following measures can be taken to relieve symptoms: 1. Cold compress: Apply an ice pack, cold milk, or a refrigerated soothing mask gently to the affected area to lower skin temperature and reduce inflammatory responses, thereby alleviating itchiness. Be careful not to apply cold compresses for too long to avoid frostbite. 2. Moisturizing and skin repair: Choose gentle, non-irritating moisturizing products, such as creams, lotions, or masks containing aloe vera, allantoin, or green tea extract, to provide adequate hydration and nutrients to the skin and promote the repair of the skin barrier. 3. Avoid irritation: Use cosmetics and skincare products that are alcohol-free, fragrance-free, and suitable for sensitive skin. Avoid excessive rubbing or squeezing of the skin to minimize irritation. 4. Medication: If symptoms are severe, antiallergic medications such as antihistamines (e.g., loratadine) or topical anti-inflammatory creams (e.g., hydrocortisone cream) may be used under a doctor's guidance to reduce itching and inflammation. 5. Sun protection: When going outdoors, apply sunscreen with a high SPF value and wear protective items such as hats and sunglasses to reduce UV damage to the skin. 6. Seek medical advice: If the itching persists or is accompanied by other uncomfortable symptoms such as redness, swelling, or blisters, consult a doctor promptly to rule out other possible skin conditions and receive professional treatment.
