The present invention provides a method for determining a sensitivity to ultraviolet light non-invasively and immediately. A method for determining a UV sensitivity is provided involving: a step of irradiating the skin of a test subject with ultraviolet light to determine the UV sensitivity using the amount of biophotons to be detected within a specific period after the irradiation, wherein 50% or more of the specific period overlaps a period from 1 to 3 minutes after the irradiation.

Method for determining ultraviolet light sensitivity

A method and apparatus for analyzing skin surface conditions which includes transferring horny cells from a skin surface of a subject onto an adhesive face of a base sheet. In addition, a learning-type image measurement system equipped with autocorrelation mask patterns is executed on a morphology of the horny cells in the image, thus judging at least one of a degree of overlapping, a degree of ellipticity and a degree of area of the horny cells. Further, the skin surface conditions are analyzed using this information.

Method for analyzing skin surface and apparatus therefor

A surface profile analyzer of the present invention is a device chiefly for analyzing the profile of the skin surface of a human. It has a ring-shaped illuminating device for irradiating a predetermined place of a test surface from all peripheral directions thereof, and an image pick-up device for photographing the test surface illuminated by the ring-shaped illuminating device. A digital signal generating device for converting the image signal of the test surface coming from the image pick-up device into a digital signal is used in conjunction with a computer to analyze the surface profile.
