CA 2609413

Images of a first and a second area of skin of an individual are obtained (s1, s3) wherein one of said first and second areas of skin comprises an area of skin of the individual generally not exposed to sunlight. The images are then processed (s2,s4) to determine the concentration and distribution of one or more chromophores in the imaged areas of skin. A relative measure of skin damage is then calculated (s5) using the determined of concentrations and distributions of chromophores in said imaged areas of skin. The calculated measure for an area of skin can be based upon determined co-variances for the distribution of chromophores in the sampled areas. Differences between measurements for exposed and unexposed areas of skin provide the relative measure of sun damage.
