Risk factors

Risk factors for having an allergic reaction to sunlight include:

• Race. Anyone can have a sun allergy, but certain sun allergies are more common in people with lighter skin.
• Exposure to certain substances. Some skin allergy symptoms are triggered when your skin is exposed to a substance and then to sunlight. Common substances responsible for this type of reaction include fragrances, disinfectants and even some chemicals used in sunscreens.
• Taking certain medications. A number of medications can make the skin sunburn more quickly — including tetracycline antibiotics, sulfa-based drugs and pain relievers, such as ketoprofen.
• Having another skin condition. Having dermatitis increases your risk of having a sun allergy.
• Having blood relatives with a sun allergy. You're more likely to have a sun allergy if you have a sibling or parent with a sun allergy.
