Embodiment Construction

[0084] figure 1 The system 1 according to the invention is shown comprising a portable device 20 and a color reference chart 30, which will now be described in detail in turn.

[0085] Color Reference Chart

[0086] figure 2 Non-limiting examples of graphs are shown.

[0087] The diagram comprises at least one region, preferably a plurality of regions, whose color coordinates are precisely known in a reference color space, preferably in the CIE (1976) L*a*b* color space.

[0088] Preferably, the diagram is made to be as insensitive as possible to different illuminants, and thus can be made using molds that are weakly metameric or non-metameric, especially with respect to the standard CIE illuminants D65, A and CWL .

[0089] Preferably, the color reference chart comprises at least three different gray levels G1, ..., Gn and at least three different colors C1, ..., Cm, preferably at least six gray levels and six colors, for example two flesh tones , two blues, one red a...

Abstract

Cosmetic method in which: a) a color is acquired from a region of the body of an individual, by using a device (20) equipped with a color camera (21) and by placing a color reference chart (30) in the field of said camera during the acquisition; and b) using the device, and the color acquired in a), and optionally knowledge of the tanning pathways of various skin colors, at least one indication is delivered concerning skin type and/or at least one indication is delivered concerning at least one skin color obtainable by the individual via the pigmentation or depigmentation process and/or at least one indication is delivered concerning photoprotection and/or application or administration of a product intended to temporarily modify the color of the skin.

Description

technical field [0001] The present invention relates to skin pigmentation and provides advice on photoprotection to be applied and / or to the various skin colors that can be obtained by tanning. Background technique [0002] The idea of ​​differentiating various skin types based on their sensitivity to solar radiation has been around for a long time. Thus, as early as 1977 the Fitzpatrick classification differentiated the six paradigms of paradigms I through VI from non-tanned Caucasian skin to hyperpigmented African skin. [0003] Subsequently, A. Chardon, I. Cretois, C. Hourseau suggested a more precise classification in Skin color typology and suntanning pathways International Journal of Cosmetic Science 13, 191-208 (1991). This classification is based on the knowledge of the CIE (1976) L*a*b* color coordinates of the skin and the calculation based on the individual type angle (ITA°)=(arctan((L*-50) / b*))*180 / pi . According to this classification, high ITA° angles charac...
