Less Common Sun Allergies
2. Photoallergic eruption
Are you using a new medication or a new body lotion? Photo-allergic eruption is triggered by the effect of sunlight on a chemical that has been applied to the skin or ingested, such as prescription medication. This usually causes an itchy red rash or tiny blisters. In some cases, photo-allergic eruption spreads to skin covered by clothing. Common prescription medication that can cause a photo-allergic eruption include antibiotics, diuretics for high blood pressure and heart failure, and certain oral contraceptives. In most cases, skin symptoms disappear after the offending chemical is identified and no longer used.
Here is a list of the 30 most common substances causing photosensitivity
3. Solar urticaria
This form of sun allergy is a very rare condition. It produces hives on sun-exposed skin. Solar urticaria most often affects young women. Hives usually appear on uncovered skin within minutes of exposure to sunlight. Symptoms typically fade within 30 minutes to 2 hours. However, they usually come back when skin is exposed to sun again.
What Causes Photosensitivity In Children
There are many causes of photosensitivity in children. Sometimes certain medications, like some antibiotics and a type of acne treatment, can cause a patients skin to be more sensitive and reactive to light. This is because chemicals in the medication reach the skin and are activated by light, leading to skin damage that can look and feel like a sunburn .
- Figure 1 – Causes of photosensitivity in kids.
- Chemicals from certain medications can be activated by light and cause severe sunburns. In erythropoietic protoporphyria, proteins called porphyrins build up in cells, resulting in photosensitivity. Xeroderma pigmentosum is caused by problems with DNA repair following sunlight damage. This can result in blisters and skin cancer. In cutaneous lupus, the immune system attacks skin tissue by mistake, resulting in various types of skin rashes. Solar urticaria happens when UV light activates IgE proteins on white blood cells, producing itchy red hives on the skin.
Home Treatments For Sun Allergies
If you know that its likely to disappear quickly, then you might prefer to wait for it to clear up on its own. In the meantime, you might like to try a couple of things to ease your discomfort whilst you wait for it to go away: – Keep the skin moisturised – provided you dont have particularly sensitive skin, moisturisers can help with cracked or dry skin that can occur following a reaction to the sun- Use soothing creams – if your skin feels particularly sore, a solution like calamine lotion or aloe vera can help to soothe the skin whilst the allergy clears up.

Desensitisation Or Uv Treatment
It’s sometimes possible to increase the resistance of your skin to the sun.
This involves visiting a hospital dermatology department 3 times a week for 4 to 6 weeks in the spring.
Your skin is gradually exposed to a little more UV light every visit to try to build up your skin’s resistance.
The effects of desensitisation are lost in the winter, so you’ll have to build up your resistance again in the spring.
What Can I Expect If I Have A Sun Allergy
The prognosis for people with a sun allergy varies widely. Some people appear to outgrow the condition. But many can experience symptoms for 10 to 15 years or longer.
An episode of sun allergy often resolves a few hours to days after you get out of the sun. But the rash can last a couple of weeks. The rash generally doesnt leave any scars unless you scratch and damage your skins surface.

Rash 101: When to seek medical treatment
Rashes can appear as blotches, welts, or blisters. Find out when you need to see a dermatologist for medical treatment.
To the untrained eye, all rashes may look alike and seem easily treatable with over-the-counter oral antihistamines or hydrocortisone cream. However, it is not always so simple, say dermatologists. Rashes can appear as blotches, welts, or blisters they can be red, itchy, scaly, or dry and they can occur in one area of skin or all over the body. In addition, some rashes may come and go, while others never seem to go away.
Although most rashes are not life-threatening, some rashes can signal something more serious. If you have a rash and notice any of the following symptoms, see a board-certified dermatologist or go to the emergency room immediately:
The rash is all over your body. A rash that covers the body could indicate something concerning, such as an infection or allergic reaction.
You have a fever with the rash. If this is the case, go to the emergency room. This could be caused by an allergic reaction or an infection. Examples of rashes caused by infection include scarlet fever, measles, mononucleosis, and shingles.
The rash is sudden and spreads rapidly. This could be the result of an allergy. Allergies to medications are common, and some can be serious. If breathing becomes difficult, go to the emergency room or call 911.
The rash is painful. Painful rashes should quickly be evaluated by a physician.
How Is Photosensitivity Diagnosed
Photosensitivity is sometimes confirmed by artificial light from various different sources and at different doses is shone on small areas of the skin to see whether the rash can be reproduced, or if sunburn occurs more easily than expected. These tests can be difficult to perform and to interpret and are only available in specialised centres.
Contact photosensitivity can be tested by , in association with standard patch tests. Adhesive patches containing known photosensitising materials are applied to the upper back, removed after two days, and light is shone on the area. The reaction is observed two days later.
Investigations may include:
- Connective tissueantibodies including antinuclear antibodies , extractable nuclearantigens
- Porphyrins in blood, urine and faeces
Patients suspected of porphyria cutanea tarda may also have liver function tests and iron tests.

Sun Allergies On The Face
While its likely that a sun rash will appear somewhere else on your body, its important not to forget to protect your face too. If you do have a reaction on your face, this can be particularly uncomfortable if the skin becomes dry or cracked.

What Causes Sun Allergy
The exact cause of sun allergy isnt fully understood but experts believe that sunlight triggers an allergic reaction and affects the way your skin heals after a burn. Sometime around puberty, children who are prone to sun allergies can develop them. Allergies to sunlight are not uncommon in children and teenagers but they usually go away as the child ages. Sun allergies can also develop in adults.
Sun allergy rash typically appears within hours after exposure to sunlight, but it can take up to 24 hours for symptoms to appear after exposure to fluorescent lights. The rash usually appears on areas of skin that have been exposed directly to sunlight or artificial light sources such as fluorescent bulbs, tanning beds, and halogen lamps.
Although most rashes appear on exposed parts of the body such as the face, neck, arms and hands, they sometimes occur on parts of your body covered by clothing if they were exposed earlier in the day.
How Do Doctors Help Patients With Photosensitivity
Unfortunately, there is no permanent cure for photosensitivity. Doctors can help patients feel more comfortable when they have rashes, and can help prevent new skin rashes from developing.
First, it is especially important for patients with sun sensitivity to protect their skin from the sun, to avoid skin rashes . Doctors encourage patients to use sunscreen with a sun-protection factor of at least 30. SPF 30 means that it would take patients 30 times longer to burn than if they were not wearing sunscreen. Patients with photosensitivity are also recommended to wear protective clothing, such as hats and long sleeves. However, the skin produces vitamin D when it is exposed to sunlight, and vitamin D is essential for keeping our bones strong, among other functions. Avoiding the sun can lead to low vitamin D levels, so patients with sun sensitivity who avoid direct sunlight should have their vitamin D levels monitored by their doctors, and take supplemental vitamin D if their levels are too low .

What Causes Solar Urticaria
The exact cause of solar urticaria is unknown. It occurs when sunlight activates the release of histamine or a similar chemical in your skin cells. The mechanism is described as an antigen-antibody reaction.
That type of reaction occurs when your immune system produces antibodies to counteract the particular antigen or irritant that reacts to the sunlight. Hives are the resulting inflammatory reaction.
You may have an increased risk for solar urticaria if you:
- have a family history of the condition
- have dermatitis
- regularly use perfumes, disinfectants, dyes, or other chemicals that may trigger the condition when exposed to sunlight
- use antibiotics or other medications, including sulfa drugs, that may trigger the condition
In some cases, particular wavelengths of ultraviolet light trigger the allergic reaction. Most people with solar urticaria react to UVA or visible light.

In addition if you notice sun sensitivity and rashes and have other symptoms , make an appointment with your primary care doctor. A skin rash in the sun can also be a sign of certain autoimmune diseases, such as lupus, the Lupus Foundation of America points out.
Sun allergy symptoms from PMLE go away on their own within about 10 days, but Solar urticaria, on the other hand, can take days to weeks to disappear. In the meantime, there are a few treatment options that can help you find relief.
For solar urticaria or PMLE, consider taking an over-the-counter antihistamine to relieve itchiness, advises Dr. Hale. Some examples are loratadine, also known as Claritin, and Diphenhydramine . These meds quell the histamine response in hives from solar urticaria, but also the reaction in PMLE.
Keeping skin cool with cold compresses and avoiding hot temperatures, excessive perspiration, and additional sun will also help you feel more comfortable as your skin repairs, adds Dr. Massick.
