Abstract:
An evaluation method for evaluating an ultraviolet radiation protection effect in a measurement sample applied on an application member includes the first step of switching to a first filter for measuring a spectral transmittance before photodeterioration by emission of light from a light source, and measuring the spectral transmittance, the second step of switching to a second filter for ultraviolet irradiation and causing the photodeterioration by the emission of the light after the measurement by the first step, and thereafter, switching to the first filter and measuring the spectral transmittance, and the third step of evaluating the ultraviolet radiation protection effect based on a change over time in the spectral transmittance obtained by the second step. Each of the first and second filters includes multiple light source filters. The first filter includes ND filters switchable in accordance with the light amount of the light source in the light source filters.
Abstract:
Provided are a counseling method and counseling device which present a skincare advice appropriate to a user. The counseling device includes an obtaining unit that obtains genetic information representing a result of a genetic test on a user and stratum corneum information representing a result of a stratum corneum test on the user; a skin constitution determining unit that determines skin constitution of the user, based on the genetic information; a skin capability determining unit that determines skin capability representing a skin condition of the user, based on the stratum corneum information; an identifying unit that identifies a skincare advice and/or a cosmetic to be proposed to the user, based on the skin constitution and the skin capability; and a presenting unit that presents counseling information including information on the skincare advice and/or cosmetic to the user.
