What Is Photosensitivity And What Substances Affect It?
Photosensitivity is a condition in which the skin reacts abnormally to light, especially UV rays or sunlight, due to the presence of medications, hormones, or heavy metals in the human body. Medications such as psoralen, diuretics, birth control pills, high blood pressure medicine, and antibiotics may affect photosensitivity. Certain foods such as citrus fruit and celery can increase photosensitivity.
