Abstract: The invention relates to a composition which contains at least one plant product and at least one texturing agent, to a kit for manufacturing a cosmetic composition containing these ingredients, and to a method for manufacturing a cosmetic composition and the use of said cosmetic composition to purify, hydrate and/or enhance the radiance of the skin.

Abstract: The present invention provides a kit comprising: a plurality of ranges of cosmetic products, each range containing a set of products associated with a common level of skin lightness, the level of lightness being identified by an identifier; and an analysis system for analyzing at least one image of the skin, and configured to deliver an identifier representative of the lightness level of the analyzed skin, the identifier being one of the identifiers of said ranges of products.

Abstract: The invention relates to apparatus for measuring color, the apparatus comprising: an acquisition system including a video camera and processing means organized to respond to the signals delivered by the camera to determine the tristimulus values of the color of the object in a reference calorimetric system by using a transfer matrix to transform the calorimetric system associated with said acquisition system into the reference calorimetric system, and to determine a correction function &Ggr; to correct the non-linearities of said acquisition system.

Abstract: A process for improving the results of cosmetic treatments on bleached hair is provided.

Abstract: The present invention provides a process for bleaching a lock or portion of lock of hair, at least partially, by irradiation of the lock using a laser beam in the form of pulses, and a device for implementation of same.

Abstract: A process for bleaching at least one lock or portion of a lock of hair, at least partially, by irradiation is provided.

Abstract: A colorimetric measurement head, for determining the internal color of a non-opaque material, in particular the internal color of the human skin, includes an emitter which emits light, towards the material to be studied, and is separated by an opaque wall from a emitter which receives light which has penetrated into the material and which is reflected thereby. An external surface of the head, which is positioned at the material to be studied, and contacts this surface either by direct application against the surface, or with optical wetting. The light received by the detector comes from the interior of the material, whereas the light possibly reflected by the surface of the material or coming directly from the emitter cannot reach the detector because of the opaque separating wall.

Abstract: Use of a colloidal suspension based on inorganic fillers, which can be prepared by the sol-gel process, as a cosmetic composition for treating the skin, hair and/or nails for the purpose of forming, after evaporation of the liquid medium of the suspension, an inorganic film on the skin, hair and/or nails.
