Sun Allergy

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.

Rarely, your healthcare provider may order a skin biopsy to look at skin cells under a microscope.
