1. A device for determining a skin inflammation score or value, comprising an optoelectronic measuring instrument or device, preferably a 3D scanner, for taking a three-dimensional image of an inflammation area on human or animal skin, wherein area-related, space and color values of the three-dimensional image are detectable by the optoelectronic measuring instrument, a processing or computing unit for calculating the skin inflammation score from the area-related, space and color values detected by the measuring instrument, and a display unit for displaying the calculated skin inflammation score, wherein the processing unit distinguishes the area-related values of the scanned three-dimensional image into an inflammation focus and a focus-surrounding area adjoining and surrounding the inflammation focus by delimiting the color values of the individual pixels and by delimiting the space values of the individual pixels and in that each color value corresponds to a magenta value in the CMYK color model.
