Some photosensitizing agents, such as St. John's Wort, appear to increase the incidence of inflammatory skin conditions in animals and have been observed to slightly reduce the minimum tanning dose in humans. [35] [36] Some examples of photosensitizing medications (both investigatory and approved for human use) are: St. John's Wort [36] 9-me-bc ...
Photosensitivity is the amount to which an object reacts upon receiving photons, especially visible light.In medicine, the term is principally used for abnormal reactions of the skin, and two types are distinguished, photoallergy and phototoxicity.
Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity). [1] PDT is used in treating acne, wet age-related macular degeneration, psoriasis, and herpes.
In rare individuals an atypical response may result in serious discomfort, disease, or injury. Some drugs have a photosensitizing effect. Properties of natural or artificial light that may abnormally affect people include: Timing of light (upset of normal circadian rhythms, seasonal affective disorder, sleep disorders)
The procedure involves the application of photosensitizing compounds, also called photoantimicrobials, which, upon activation by light, generate reactive oxygen species (ROS). These ROS lead to the oxidation of cellular components of a wide array of microbes, including pathogenic bacteria , fungi , protozoa , algae , and viruses .

Phototoxicity, also called photoirritation, is a chemically induced skin irritation, requiring light, that does not involve the immune system. [1] It is a type of photosensitivity.
