Vampires aren’t the only creatures averse to sunlight. But unlike Edward Cullen, those unfortunate enough to suffer from a sun allergy don’t just endure a conspicuous sparkle. They usually deal with worse skin problems ranging from a rash to blisters.

So, what is a sun allergy? If you have it, are you doomed to avoid the morning sun and be housebound during daylight? This article answers the basic questions you may have about skin photosensitivity. If you suspect you have this condition, consult with a specialist immediately.

What Causes a Sun Allergy?

According to DailySkin Clinic’s dermatopathologist Riza Milante, FPDS, DDSP-PDS, ICDP-UEMS, a sun allergy is not an official diagnosis but rather a broad, colloquial term to describe reactions to sun exposure. “Often, it refers to solar urticaria or polymorphous light eruptions (PMLE),” she explains.

Solar urticaria is a chronic photosensitivity disorder that causes those afflicted to break out in a rash, welts, or hives. Other symptoms include a burning or stinging sensation, redness, and swelling. PMLEs typically exhibit the same signs but are triggered by sudden contact with sunlight after a period of reduced exposure. For example, an influx of PMLEs usually occurs during the spring – after the relative darkness of winter.

Most “sun allergies” can be inconvenient, even debilitating, and may require careful maintenance, but they are hardly life-threatening. However, extreme sensitivities can be dangerous. Take, for example, Bella Thorne’s character in the 2018 film Midnight Sun. She has xeroderma pigmentosum, a rare genetic disorder that impedes the body’s ability to repair damage caused by ultraviolet light. XP patients usually battle skin and eye abnormalities and face a higher chance of certain cancers.

A sun allergy can be a condition in itself, such as the ones mentioned above. However, it can also be a side effect of medication (oral isotretinoin and topical retinoids, among others), chemicals you apply on the skin (triclosan and certain fragrances), and other skin diseases, like lupus, says Dr. Milante.

Can You Treat a Sun Allergy?

Your photosensitivity is manageable, especially if you exercise precautions.

Dr. Milante adds: if you suspect photosensitivity, work with your doctor to figure out the root of the issue. Treating the cause will likely solve the sun allergy problem. Another curative option is UVA (Ultraviolet A) radiation hardening, wherein the skin is incrementally exposed to light to make it more resistant.

According to a 2018 study in the International Journal of Environmental Research & Public Health, early exposure to sunlight – such as when you were a kid – could reduce the likelihood of photosensitivity.

Dr. Milante also advises precautions, such as avoiding triggers and diligence when it comes to sun protection.

“Use a broad-spectrum sunscreen or sunblock with high SPF to protect the skin from harmful UV rays,” she suggests – advice that is useful to everyone, with or without a sun allergy.
