## Abstract

A temporary tattooing ink is produced from concentrated genipin. In one embodiment, the concentrated genipin forms part of a solution. In another embodiment, the genipin is provided in a gel form which also includes a solvent and a thickening agent. Finally, an applicator is described into which genipin may be embedded for applying to a user's skin.
