Abstract
The present invention relates to a cosmetic ink application device which functions by producing a region as an alignment marker on human skin and detecting the region to align an applicator with the skin, and a method thereof. A cosmetic ink application device according to the present invention comprises: a light source for irradiating human skin with ultraviolet light; an optical sensor for detecting intensities of fluorescence in a ultraviolet range and/or a visible light range emitted from the skin in response to the irradiation of the ultraviolet light; an applicator for applying a cosmetic ink to the skin; a head portion for holding the light source, the optical sensor, and the applicator; and a controller, wherein the controller defines a region on the skin, which emits fluorescence having an intensity different from fluorescence emitted from other regions of the skin when irradiated with the ultraviolet light, as a marker region, wherein the controller determines a position of the ink application based on the marker region, and wherein the controller causes the applicator to apply the ink on a predetermined portion of the skin.
