Claim:
1. A method of quantifying an under eye appearance of skin of a human subject, comprising: a. capturing a digital image of the subject with a digital image capturing device; b. detecting an eye area to be evaluated on the digital image of the subject; c. selecting a region of interest in the detected eye area based on a location of the eye and a location of a corresponding eyebrow and confirming the region of interest by drawing a horizontal reference line connecting two corners of the eye, and determining a dimension of the region of interest, wherein the dimension of the region of interest is based on a dimension of the horizontal reference line and the locations of the eye and the corresponding eyebrow; d. determining a series of skin reflective intensity data within the region of interest, comprising: e. generating a skin reflective intensity profile from the series of skin reflective intensity data; f. quantifying a value of the subject's under eye appearance of skin from the skin reflective intensity profile by calculating a mean square error (MSE): wherein n is the number of discrete slices, and r i is the absolute value of the difference between the average skin reflective intensity in each discrete slice and a predefined intensity.
