GlossaryPhototoxicity

skin reaction from sunlight exposure to certain chemicals

Phototoxicity refers to a skin reaction that occurs when certain chemicals or medications on the skin are exposed to sunlight, leading to damage. This can result in redness, inflammation, and sometimes blistering, similar to a severe sunburn. For professionals, it's important to note that phototoxic reactions are typically caused by the interaction of ultraviolet (UV) light with photosensitizing agents, which can be found in some topical treatments, systemic medications, or even certain plant compounds.
