The following image is of a soap that appears to be popular in the Philippines, where most women (and quite a few of them men) are obsessed with whitening their skin and maintaining a fair complexion. The image of a painted geisha face very effectively communicates the idea of a fair complexion and the purpose of the soap.
It also puts across the idea that by using the soap you will be sophisticated, artistic and elite, which are all qualities possessed by true Japanese geisha. Contrary to what most people believe, the highest class of geisha do not sell sex but are instead entertainers who sell their skills with instruments, gaming and conversation to high class clientele like politicians and wealthy businessmen.
