A method for determining UV coverage on an irradiation target in real time comprises the steps of irradiating an irradiation target () with light including UV light () immediately after applying a sunscreen (); detecting an amount of fluorescent light () emitted from the irradiation target in response to the light irradiation and storing the amount of the fluorescent light as reference data; irradiating the irradiation target () with the light including UV light () after a predetermined passage of time, or after applying a predetermined stress on the sunscreen (); detecting an amount of fluorescent light () emitted from the irradiation target in response to the light irradiation and storing the amount of the fluorescent light as measurement data; and determining UV coverage by dividing the amount of the fluorescent light of the reference data by the amount of the fluorescent light of the measurement data, wherein the irradiation target () includes at least one substance emitting fluorescent light in response to the light irradiation.

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.

The present invention relates to a device () for supplying a mist of liquid (F). The device () is used in combination with a container () with an opening () for containing the liquid (F). The device () includes a main body () comprising: (i) a center axis (C); (ii) a liquid chamber () formed inside the main body (), into which a predetermined amount of liquid (F) can be taken up; (iii) a first port () formed in a base wall () of the main body () forming a bottom surface () of the liquid chamber () so as to face the opening () when the device () and the container () are combined with each other, through which the liquid (F) can flow; (iv) a second port () formed in the base wall () at a position different from the position where the first port () is formed so as to face the opening () when the device () and the container () are combined with each other, through which the liquid (F) can flow; and (v) an aperture () connected to the liquid chamber (), through which a mist of liquid (F) can be released to the outside of the main body (). The device () further includes: a connecting section () provided on the main body () so as to extend from it in a direction away from the base wall () and used for connecting the container () to the main body (); an atomizing element () interposed between the liquid chamber () and the aperture () to atomize the liquid (F) taken up in the liquid chamber () and release a mist of the liquid (F) to the outside of the main body () from the aperture (); a first valve () mounted on the main body () corresponding to the first port (), wherein the first valve () permits the liquid (F) in the container () flowing into the liquid chamber () through the first port () under the influence of gravity, and prevents the liquid (F) in the liquid chamber () flowing into the container () under the influence of gravity; and a second valve () mounted on the main body () corresponding to the second port (), wherein the second valve () prevents the liquid (F) in the container () from flowing into the liquid chamber () through the second port () under the influence of gravity, and selectively permits or prevents the liquid (F) in the liquid chamber () flowing into the container () through the second port () under the influence of gravity.
