Sun allergy is a condition characterized by reactions such as redness, itching, and blisters on the skin when exposed to sunlight. This condition can be more common, especially in spring and summer months, when sun exposure increases. There are various types of sun allergies, the most common being polymorphic light eruption (PMLE) and solar urticaria.

Polymorphic Light Eruption (PMLE)

PMLE is the most common form of sun allergy and generally manifests as a rash on the skin a few hours after sun exposure. These rashes typically occur in sun-exposed areas such as the chest, arms, and legs. PMLE symptoms can be controlled with sun protection and treatments targeting the allergy.

Solar Urticaria

Solar urticaria is a reaction where itchy and raised redness appears on the skin immediately after sun exposure. This condition generally starts within a few minutes and quickly improves once out of the sun.

Diagnosis and Treatment

The diagnosis of sun allergy is usually made through the patient’s medical history and observation of symptoms. In some cases, more specific tests may be conducted. Treatment typically depends on the severity of the symptoms and may include:

  • Sun Protection: The most effective precaution for individuals with sun allergy is to avoid direct sunlight. Protective clothing such as wide-brimmed hats, long-sleeved shirts, and sunglasses can be used.
  • Sunscreen: High SPF, broad-spectrum sunscreens provide protection against UVA and UVB rays.
  • Topical Treatments: Mild corticosteroid creams may be used to alleviate skin inflammation and itching.
  • Antihistamines: Oral antihistamines can relieve allergic reactions such as itching and redness. It can be challenging to prevent sun allergy completely, but appropriate sun protection measures can significantly control symptoms.


Before going into the sun, using high-protection sunscreen in skincare routines and avoiding being outside during the peak sunlight hours are crucial.

Sun allergy can make summer months challenging for some people but can be managed with the right treatment and precautions. Noticing suspicious symptoms and consulting a specialist doctor (dermatologist) is important for accurate diagnosis and treatment.

Risk Factors for Sun Allergy

The risk of developing a sun allergy can be higher in some individuals due to genetic predisposition. Sun sensitivity is more common in those with family members who have sun allergies. Fair-skinned individuals often have more sensitivity to the sun. Some medications and cosmetic products can also increase photosensitivity in the skin, leading to sun allergy symptoms. 

In children, sun allergy can be more pronounced due to their still-developing immune systems. Therefore, before children go out in the summer, it is important they use high-factor sunscreens and wear protective clothing.

Daily Recommendations for Sun Allergy Prevention

It may not be possible to completely prevent sun allergy, but symptoms can be minimized with the right lifestyle habits. Limiting exposure to UV rays is the fundamental step. The hours between 10:00 AM and 4:00 PM are when the sun's rays are most intense. Avoiding going out or staying in the shade during these hours is beneficial for skin protection.

Incorporating high SPF sunscreens into your daily skincare routine is effective against sunburns and symptoms of sun allergy. These sunscreens should be water-resistant and reapplied every two hours. Products suitable for allergic skin types, which are free from perfumes and alcohol, should be chosen.

Nutritional Habits for Sun Allergy

A balanced diet is also essential for enhancing the skin's resilience to the sun. Foods high in antioxidants protect skin cells from the harmful effects of free radicals. Vegetables and fruits rich in vitamins A, C, and E can increase skin resistance to sun rays. Foods containing omega-3 fatty acids may also be beneficial due to their anti-inflammatory properties.

Frequently Asked Questions 

How is sun allergy treated?

Sun allergy symptoms naturally lessen as the duration of sun exposure is reduced. However, if the symptoms are severe, it is essential to consult a dermatologist. Topical corticosteroid creams, antihistamine medications, and soothing lotions can be used in the treatment process. Methods like sun acclimatization therapy can benefit some individuals. 

When do sun allergy symptoms appear?

Sun allergy symptoms can vary from person to person and usually appear within a few minutes to a few hours after sun exposure. In individuals with polymorphic light eruption, rashes become noticeable hours later, while itching and swelling in solar urticaria can be observed within minutes. Symptoms can be more severe in the spring months when the skin is not accustomed to the sun.

How is sun allergy identified and treated in children?

In children, sun allergy may manifest as itchy redness and small blisters, especially on the face, arms, and neck. Since children may not be able to express these symptoms, careful observation is crucial. During the treatment process, sunscreens formulated specifically for children should be used, they should be encouraged to drink plenty of fluids, and antihistamines recommended by a pediatrician should be chosen for allergic reactions.

Do treatment methods for sun allergy provide a permanent solution?

Treatment methods for sun allergy typically control symptoms temporarily. A permanent solution requires the immune system to develop tolerance to the sun. However, sun protection habits often need to be sustained throughout life. With modern dermatological approaches, the quality of life for individuals with sun allergy can be significantly improved.
