What condition results from UV exposure after essential oils from citron rind contact the skin?
Phytophotodermatitis
A distinct, non-allergic skin reaction known as phytophotodermatitis can occur when components found in citrus fruits, specifically the essential oils concentrated in the rind, interact with ultraviolet (UV) radiation from sunlight. This process is characterized as a chemical burn reaction. If these oils transfer to the skin—for example, during extensive handling while peeling or zesting citron—and the area is subsequently exposed to the sun, a delayed adverse event follows. This manifestation typically includes redness, blistering, and subsequent discoloration, known scientifically as hyperpigmentation, appearing hours or even days after the initial exposure event.
