bindi
A forehead mark that consists of a colored dot (or sticker) worn on the center of the forehead. It is worn by Hindus, Jains and Buddhists from the Indian subcontinent. The mark is always applied close to the eyebrows or in the middle of the forehead
Note that China historically had a mark similar to the bindi, called the cinnabar mole (朱砂痣, zhushazhi) or the dot cinnabar (点丹 diandan). The cinnabar it was made from gave it the red pigment, but was highly toxic. It was used as a status symbol, with links to taoism.
Use forehead mark or circle facial mark instead if the image has no correlation with Hinduism, Buddhism or Jainism.
