Abstract:
A pore ruler for objectively measuring attributes of facial skin pores and methods of using same. The pore ruler device includes a scale having indicia of at least two different pore attributes captured in a medium, determined by the following steps: (i) Taking multiple photographs of multiple subjects; (ii) Sorting the photographs, thereby classifying them according to said pore attributes to obtain sorted data; (iii) Analyzing said sorted data; (iv) Selecting representative images from each bin, thereby creating a pore ruler scale; and (v) Validating said pore ruler scale by clinicians and consumers to show that consumers can distinguish pore attributes and correlate them with said scale. A cosmetic product system is also provided which includes a cosmetic composition for reducing the appearance of facial skin pores, and a pore ruler device packaged with the composition. A method for assessing pore attributes on the pore ruler scale, as well as of evaluating progress of the combat against the signs of pores occurring over a period of time within which the composition is applied to an area of skin being monitored is provided.
