What should I do if my skin is allergic to ultraviolet (UV) radiation?

In daily life, a very small number of individuals are allergic to ultraviolet (UV) radiation. So, what should one do if their skin is UV-sensitive?

What to Do If Your Skin Is Sensitive to Ultraviolet Radiation

The primary cause of UV-induced skin sensitivity is related to individual constitution—namely, the patient’s skin is inherently more susceptible to UV exposure and thus prone to allergic reactions. Clinical manifestations typically include erythema, swelling, papules, and even vesicles on sun-exposed areas such as the face, the V-shaped area of the upper chest, and the lateral aspects of the forearms. These lesions are commonly accompanied by pruritus; in severe cases, patients may experience pain and discomfort.

Management strategies include: First, minimizing UV exposure through protective measures—such as applying broad-spectrum sunscreen, using umbrellas, and wearing hats. Second, symptomatic anti-inflammatory and antipruritic therapy. For example, oral antihistamines—including loratadine tablets and cetirizine tablets—may be prescribed. Topical corticosteroids or nonsteroidal anti-inflammatory agents—such as compound flumetasone ointment, difenhydroxylamine cream, fluocinolone acetonide ointment, or compound indomethacin tincture—may also be used. Additionally, patients with UV sensitivity should avoid consuming phototoxic foods—for instance, ingesting light-sensitive vegetables (e.g., shepherd’s purse) or certain grain-based foods may exacerbate clinical symptoms upon UV exposure, particularly after prolonged sun exposure.
