a) acquiring at least one image of the facial region using a camera and generating image data representing the at least one image;

b) processing the image data and additional information with a processor to obtain a treatment recommendation, wherein the additional information includes at least an indication of a condition affecting an appearance of the facial region and an indication of a treatment type to treat the condition, wherein the treatment type is one of local injections of a substance, external application of a substance, intake of a composition, internal use of a certain pharmaceutical substance, or combinations thereof;

c) outputting the obtained treatment recommendation to a display screen or to a further computer;

wherein the step of processing the image data includes improving the image quality, identifying and/or measuring facial structures and/or generating statistical data,

wherein the processing step includes a comparison substep to compare with a comparison module of the processor information derived from the image data with reference information to obtain a reference measure, the reference measure being an assessment of the severity of a condition, an assessment of the effects of the condition on appearance compared to a standard, a target state or a comparison individual or group and/or an assessment of progression or regression of the condition compared to an earlier point in time, wherein the reference measure is selected from a group consisting of a binary information, a ternary information, a value, and a multi-dimensional quantity, and

wherein the processing step further includes a classifying substep which is based on the reference measure and yields the treatment recommendation, wherein the treatment recommendation includes at least one of the following:
