He suspected they were due to fluid droplets, unaware that Freund in 1916 had described hyperpigmented macules due to sun exposure after the application of eau de cologne.

Several cases were reported in the 1950s and 1960s following increased use of perfumes containing oil of bergamot and the passion for sunbathing.
