Phytophotodermatitis in Adult
There is no predilection for any age or ethnicity or either sex, although phytophotodermatitis may be more noticeable in lighter skin phototypes. Bartenders and revelers handling citrus fruits are at higher risk. The condition is benign and self-limited, and treatment is supportive.
The term "Berloque dermatitis" refers to phytophotodermatitis from natural oil of bergamot in perfumes. This eruption is typically seen on the face and neck of women applying aerosolized fragrances. This has become rare since the introduction of artificial oil of bergamot.
