Causes Of Sun Allergy Rash
Having a sun allergy rash is also known as Polymorphous Light Eruption which is one form of sun allergy. The cause of having a sun allergy rash usually happens because the person has innate antibodies that are triggered when sunlight comes in contact with their skin. Their skin contains proteins that when exposed to sunlight react and change. Because of these evolved proteins the natural antibodies in your immune system respond to them and treat them like they are foreign bodies. Because the natural antibodies are not able to recognize these evolved proteins the immune response is stimulated and results in sun allergy rashes. Sometimes a sun allergy rash is referred to as photosensitivity, heat rash, or solar dermatitis.
How Is Contact Dermatitis Managed Or Treated
Treatment for both types of contact dermatitis is the same. Even with treatment, it can take several weeks for the rash to go away. Treatments include:
- Avoidance: If you can figure out whats causing the rash, take steps to avoid it or minimize exposure.
- Anti-itch creams:Corticosteroid creams can ease inflammation and itching.
- Oral steroids: Prednisone, a type of steroid, can relieve rash symptoms that dont respond to antihistamines or other treatments.
- Immunosuppressive medications: In severe cases, where repeated bouts of oral steroids are needed.

Causes Of Polymorphic Light Eruption
Polymorphic light eruption is thought to be caused by UV light altering a substance in the skin, which the immune system reacts to, resulting in the skin becoming inflamed.
It’s not passed down through families, but about 1 in 5 people with the condition have an affected relative as it’s a fairly common condition.
It’s not infectious, so there’s no risk of catching polymorphic light eruption from another person.
What Does Ple Look Like
- PLE ranges from a mild rash that lasts for only a short time to a severe and extensive eruption affecting the quality of life.
- The rash comes up equally on both sides of the body, affecting mainly those parts of the skin that are kept covered in the winter, such as the arms, the upper thighs and the upper trunk. For this reason the face, neck and backs of the hands are sometimes, but not always, affected.
- The appearance of the rash varies from person to person. The most common type has large numbers of small red bumps. In other people the rash is made up of larger red areas and small blisters. The rash of each affected person usually looks the same each time it comes back to that particular person. The rash usually disappears by itself within 7-10 days, if there is no further exposure. It heals without scaring.

Rash And Skin Disorders
A rash is an area of swollen, irritated skin that manifests in different patterns and varying shades of red, purple or brown. Some rashes are caused by allergic reactions to the environment, food or medications, while others appear because of a skin disorder or underlying disease or infection. Some clear up on their own, but others are chronic and require treatment to control symptoms.

For example, a common type of rash is contact dermatitis. It causes redness and itching in reaction to an environmental irritant that touches the skin such as poison ivy, soap, cosmetics or household chemicals. Its usually treated by over-the-counter medicines and staying away from the irritant that triggered the rash. It is uncomfortable but isnt serious or contagious.

What Are The Clinical Features Of Solar Urticaria
A stinging, itchy rash develops within minutes after a short period of sun exposure. The rash may look like weals and be red and swollen. Often the rash affects areas of exposed skin that are normally shielded from sunlight by clothing, e.g. back. The face and upper sides of the hands that are constantly exposed to the sun may be unaffected or only slightly affected. This may be put down to acclimatisation or ‘hardening’ of these chronically exposed areas.
If large areas of the body are affected, the loss of fluid into the skin may result in light-headedness, headache, nausea and vomiting.
Areas covered with thin clothing may also be affected, depending on the ultraviolet rays being emitted and the sheerness of the fabric.

Why Am I Suddenly Getting Hives From The Sun

Our Skin Research Expert Explains The Difference Between Sunburn And Sun Allergy
We know that exposure to the suns rays can cause premature aging of the skin, but in some cases it can also lead to an allergic reaction. Dr. Harvey Lui explains how to tell if that rash is from the sun and when to see your doctor.
Q: My friend says she is allergic to the sun. Is there such a thing as a sun allergy? A: Yes, people can develop an allergic reaction to the sun called polymorphic light eruption . This causes a delayed skin reaction after exposure to ultraviolet radiation, typically from the sun. People with PLE often experience a rash and itching. This differs from the pain or swelling of sunburn, which can be mistakenly called heat rash. It is actually sunlight, and not heat, that causes the skin reaction. The best way to know for sure if you have PLE, sunburn or some other type of light sensitivity is to speak with a physician.
Q: How is a sun allergy treated?A: The best defense against PLE is to block as much sunlight from reaching the skins surface as possible to prevent the return of symptoms. Patients are advised to cover up with clothing and wear sunglasses and a hat. It is also recommended to use a broad spectrum sunscreen with an SPF of at least 30, but ideally 60 or higher.

What Does A Stress Rash Look Like
Stress often affects the skin adversely. It causes the formation of a stress hormone that increases oil production in the body, making it prone to acne. Stress may also cause itchy welts to appear on the skin. These welts are commonly known as hives and can appear on any part of the skin. These welts can vary in sizes and may connect to form a larger welt.
Hives are generally red, raised, and swollen, which can be as small as a pencil tip or as large as a dinner plate, and may present with a tingling or burning sensation. Generally, a single hive disappears within 24 hours or less, and a new hive appears at a different site as the older one subsides. A bout of hives or multiple hives usually takes about 6 weeks to resolve and is known as acute hives. Hives lasting for more than 6 weeks are known as chronic hives.
Urticaria is the medical term for hives. Angioedema is an emergency condition in which the welt occurs deeper in the skin and causes the eyelids and lips to swell.
Why Do You Get Sun Rash
Prolonged exposure to the sun is one of the primary causes of sun rashes. Some people are photosensitive and are more prone to sun rash. Studies are yet to narrow down on exactly what causes a sun rash. Some experts believe it is the sun’s UV rays that cause the skin to react with a rash. In some instances, people who are sensitive to sunlamps or any artificial sources may develop a rash, resulting from an immune reaction.
Factors That Can Make Your Skin More Prone To Sun Rash Include:
- Heredity, when someone in your immediate family has the same condition
- Females are more prone to sun rash than men
- Living in colder parts of the world
- Having very fair skin
A reaction caused by sunlight on the skin, due to the application of cosmetic products, sunscreens, topical antibiotic ointments, fragrances, and prescribed oral medication, can also cause sun rash. This is known as a photoallergic eruption.
Dr. Harish Koutam, Chief Dermatologist at SkinKraft says, Polymorphous light eruption is generally uncomplicated but severe disease can lead to emotional distress, anxiety and depression. Medication that can cause this kind of sun rash includes diuretics for heart problems and high blood pressure, antibiotics, and painkillers.

What Causes The Reaction
Research into solar urticaria is ongoing, and the exact cause of the response to UV has not been established. However, it is understood to be a type of allergic reaction, known as allergic hypersensitivity .
The reaction occurs between the UV radiation and a type of chemical in the body, known as a photoallergen. The specific chemical that acts as a photoallergen remains unidentified.
Discovering this will help researchers better understand what causes the condition and may lead to more effective treatment and prevention of solar urticaria.
Drug Allergy Skin Rash
Skin tests. With a skin test, the allergist or nurse administers a small amount of a suspect drug to your skin either with a tiny needle that scratches the skin, an injection or a patch. A positive reaction to a test will cause a red, itchy, raised bump. A positive result suggests you may have a drug allergy. A negative result isnt as clear-cut.
