What makes an essential oil photosensitive?
While known for their bright, summery scents, citrus oils are among the most common essential oils that cause photosensitivity. That’s because compounds found in citrus oils—known as furanocoumarins—greatly increase UV sensitivity. And while most photosensitive oils are citrus, other oils can contain compounds or mixes of compounds that have the same effect as furanocoumarins, meaning they’re not sun-safe either. Always check the label before application to determine the oil’s photosensitivity.
