• #1 Sun Allergy: Symptoms, Causes, Treatment & Prevention

  https://my.clevelandclinic.org/health/diseases/17681-sun-allergy

  A sun allergy happens when a person develops a rash and sometimes other symptoms after exposure to sunlight. […] If you suspect a sun allergy, talk to your primary care provider or a dermatologist. […] They can diagnose the condition based on: Discussion of your symptoms. Review of medications you take and products you put on your skin. Light testing, which involves placing different light sources (artificial and natural), wavelengths and intensities a few centimeters from your skin. It helps you understand what exactly causes a reaction. Light testing can be combined with patch testing. Your healthcare provider places patches on your skin that contain chemicals suspected to cause a reaction. […] The most effective treatment for sun allergy is avoiding sun exposure. […] For people who cannot avoid the sun or who have more intense reactions, certain treatments may help: Antihistamines such as loratadine, fexofenadine and cetirizine. Corticosteroids such as prednisone. Creams to ease itchiness. Omalizumab injections. Phototherapy, a long-term treatment that uses repeat exposure to light to try to build your skins tolerance.

• #2 Sun Allergy (Photosensitivity) – Harvard Health

  https://www.health.harvard.edu/a_to_z/sun-allergy-photosensitivity-a-to-z

  Despite the name, a „sun allergy” is not truly an allergy to the sun. Instead, it is an immune system reaction in the skin triggered by sunlight, most often causing an itchy red rash. The medical term for this condition is Polymorphous Light Eruption (PMLE). […] If you have more severe sun-related symptoms especially hives, blisters or small areas of bleeding under the skin your doctor will need to make the diagnosis. In most cases, your doctor can confirm that you have PMLE or actinic prurigo based on your symptoms, your medical history, family history (especially American Indian ancestry) and a simple examination of your skin. […] If you have symptoms of a photoallergic eruption, the diagnosis may take some detective work. Your doctor will begin by reviewing your current medicines as well as any skin lotions, sunscreens or colognes you use. […] If you have symptoms of solar urticaria, your doctor may confirm the diagnosis by using photo-testing to reproduce your hives.

  https://www.health.com/sun-allergy-7563866

  You can be allergic to the sun. A sun allergy sometimes also called photosensitivity occurs when the skin is hypersensitive to ultraviolet (UV) rays, which the sun naturally emits. […] To diagnose a sun allergy, a healthcare provider will thoroughly review your personal and family medical history, ask about your symptoms (such as when they developed and how long they lasted), and perform a physical examination. […] The provider will generally try to rule out other possible causes of your symptoms. They may evaluate your symptoms using one or more of the following tests: Phototesting: This involves exposing small areas of the skin to controlled amounts of UV light to observe any allergic reactions. This test helps determine the specific wavelength of light (UVA or UVB) that triggers an allergic reaction.

  https://www.mayoclinic.org/diseases-conditions/polymorphous-light-eruption/diagnosis-treatment/drc-20355872

  Your healthcare team will ask you a number of questions about your symptoms and your medical history, such as: […] Avoid sun exposure whenever possible. If you can’t avoid the sun, use a broad-spectrum sunscreen with an SPF of at least 30 in areas that cannot be protected by clothing. Apply it generously 15 minutes before sun exposure. Reapply it every two hours or more often if you’re swimming or sweating. This won’t totally protect you from a reaction, as ultraviolet A may penetrate through most sunscreens.

  https://www.apollohospitals.com/diseases-and-conditions/sun-allergy-types-causes-symptoms-disgnosis-and-treatment

  Sun allergy is a result of the immune systems reaction to sunlight. […] The health care provider can often diagnose a sun allergy only by looking at the skin. […] To help identify the reasons which instigated the allergic reaction, doctors may also require family history and other tests for a correct diagnosis. […] The tests may include the following: Photo patch testing: This checks if the skin reacts to sensitizing substances in the sunlight. […] UV light testing: The test enables the doctors to see how the skin reacts to different wavelengths of UV light and helps pinpoint the exact allergens. […] Blood tests and skin samples: These are only required if the doctor suspects underlying conditions such as lupus that might be causing sun allergies.

  Sun allergy is a term often used to describe a number of conditions in which an itchy red rash occurs on skin that has been exposed to sunlight. […] See a doctor if you have unusual, bothersome skin reactions after exposure to sunlight. For severe or persistent symptoms, you may need to see a doctor who specializes in diagnosing and treating skin disorders (dermatologist). […] In many cases, doctors can diagnose sun allergy simply by looking at the skin. But if the diagnosis isn’t clear-cut, you may need tests to help identify what’s going on. These tests may include: […] Ultraviolet (UV) light testing. Also called phototesting, this exam is used to see how your skin reacts to different wavelengths of ultraviolet light from a special type of lamp. Determining which particular kind of UV light causes a reaction can help pinpoint which sun allergy you have.

  Sun allergy is typically caused by an immune system reaction to sunlight, UV radiation. This reaction leads to the production of antibodies and the release of histamines, resulting in allergic symptoms. Sun allergies can be triggered even by short exposure to sun. […] Diagnosing a sun allergy primarily involves a detailed review of your symptoms, medical history, and a physical examination. The doctor may also perform specific diagnostic tests to confirm the diagnosis and rule out other conditions with similar symptoms. […] One common test is phototesting, where small areas of your skin are exposed to measured amounts of UVA and UVB light to observe the reaction. This can help determine if you have a sun allergy and the type of sun allergy you have. […] In addition to phototesting, a skin biopsy might be required in some cases. This involves removing a small sample of the affected skin for laboratory analysis. This can help identify or rule out any associated conditions. […] If you notice such symptoms after sun exposure, consult a healthcare professional for diagnosis and management.

Solar urticaria usually breaks out within minutes of sun exposure, and it goes away fast if you get out of the sun. It doesnt leave any scars. […] Your doctor may also need to do one or more tests to confirm a diagnosis: Phototesting looks at how your skin reacts to UV light from a sun lamp in different wavelengths. The wavelength your skin reacts to may help identify your particular sun allergy. […] Patch testing involves putting different substances known to trigger allergies on your skin, waiting a day, and then exposing your skin to UV radiation from a sun lamp. If your skin reacts to a particular substance, that may be what triggered the solar urticaria. […] Blood tests or skin biopsies may be used if your doctor thinks your hives may be caused by another medical condition, such as lupus or a metabolic disease.

  https://dermaclub.it/en/dermatology-fact-sheets/sun-allergy-or-photoallergy-2/

  Sun allergies are an immunological response that occur when a photo allergen (a photosensitizing chemical) absorbs radiant energy and provokes an immune response. This allergy most often manifests as skin rashes and itching, although there are many different types of sun allergies, each with their own symptoms. […] Doctors can often make a diagnosis of sun allergy through a dermatological examination. Other tests that may be used are: Photosensitivity test: a small area of skin is exposed to a controlled amount of ultraviolet light. If the typical symptoms of sun allergy appear after exposure, the test confirms a diagnosis of sun allergy. Photopatch test: the skin is put in contact with the suspected allergy-triggering substance, and then exposed to ultraviolet radiation to test the reaction. In rare cases, blood tests and a skin biopsy may be recommended to rule out systemic lupus erythematosus.
