Introduction
This condition primarily occurs on areas of the body exposed to intense sunlight and is also common in high-altitude regions with strong ultraviolet (UV) radiation. When UV allergy develops, preventive measures should be taken: practice sun protection daily and wear protective gear when outdoors. Sunscreen must be applied to exposed areas such as the face and limbs. Additionally, maintain sun protection in daily life—remember to carry an umbrella or wear a sun hat when going outside.
Prolonged sun exposure and chronic ultraviolet (UV) radiation may trigger an allergic reaction, causing significant discomfort. What are the symptoms of UV allergy?
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 erythema (redness), papules, and vesicles. The longer the exposure duration, the more severe the symptoms become.
These symptoms primarily affect sun-exposed areas and are more common in high-altitude regions with intense UV radiation. When UV allergy occurs, preventive measures should be taken—regular sun protection is essential. When outdoors, wear protective clothing and accessories. Apply broad-spectrum sunscreen to exposed areas such as the face and limbs. Additionally, be mindful of phototoxic foods—such as parsley, celery, and lettuce—and limit their intake. Spicy and irritating foods should also be minimized to avoid exacerbating allergic symptoms. Topical corticosteroid ointments may be applied. For severe pruritus (itching), topical corticosteroid preparations may be used.
In daily life, remember to carry an umbrella or wear a wide-brimmed hat when going outdoors. Avoid prolonged direct sun exposure—especially on sun-drenched surfaces—to prevent post-inflammatory hyperpigmentation. Consuming foods rich in vitamin C is also beneficial: not only does it help brighten the skin, but it also inhibits melanin production. We hope this information is helpful to you.
