摘要 |
Method for determining the aptitude of a cosmetic or dermatological product for diffusing or absorbing light, has the following steps: illumination of the product (P) or a zone of a support (S) to which the product is applied with a light beam (20) incident so as to generate backscattering; acquisition of an illumination spot image; analysis of the image to determine, as a function of the variation of the luminosity, the product's aptitude for diffusing or absorbing light. Independent claims are also included for the following:- (a) a method for determining a characteristic of a cosmetic or dermatological product; (b) a method for monitoring the evolution over time of a characteristic of a cosmetic or dermatological product; a device for determining the aptitude of a cosmetic or dermatological product for diffusing or absorbing light; (c) and a fabrication method for a cosmetic or dermatological product. |
