Abstract:
A method of non-invasively analysing skin structure, comprising the steps of:(i) measuring radiation having a wavelength within a wave band extending from 600 nm and into infrared from at least one location in an area of skin under investigation so as to give an indication of papillary dermis thickness over said area;(ii) measuring skin colour co-ordinates at said at least one location in said area of skin;(iii) using data obtained in measuring steps (i) and (ii) to calculate corrected skin colour co-ordinates over said area which correspond to a predetermined papillary dermis thickness, and;(iv) comparing the corrected skin colour co-ordinates obtained in step (iii) with a reference colour co-ordinate range for healthy skin of said the same predetermined papillary dermis thickness.
