What Are the Symptoms of UV Allergy?

UV allergy is an allergic reaction that occurs when the face and limbs are exposed to sunlight. After sun exposure, the skin may develop symptoms such as redness, papules, and blisters. The longer the exposure time, the more severe the symptoms become.

These symptoms primarily occur in areas exposed to strong sunlight and are also common in high-altitude regions with intense UV radiation. When suffering from UV allergy, preventive measures should be taken. Pay attention to sun protection in daily life and wear protective gear when going outdoors. Sunscreen must be applied to exposed areas such as the face and limbs. Additionally, be mindful of certain photosensitive foods—such as parsley, celery, and lettuce—and try to consume them in moderation. Spicy and irritating foods should also be limited to avoid aggravating allergic symptoms. Topical ointments can be used. If itching is severe, corticosteroid creams may be applied.

In daily life, remember to carry a parasol or wear a sun hat when going outside. Avoid prolonged sunbathing in direct sunlight to prevent hyperpigmentation. It's also beneficial to eat more foods rich in vitamin C, which not only help whiten the skin but also inhibit melanin production. We hope this information is helpful to you.
