    摘要: The identification of new biomarkers that are specifically associated with skin dryness. These biomarkers, which are extended synaptotagmin-3 (ESYT3), Ubiquinin-carboxyl terminal hydrolase 7 (USP7), periplakine (PPL) and Late Cornified Envelop Protein 1C (LCE1C), allow for the accurate evaluation of the moisture content of the skin, and particularly allow for the diagnosis of dry skin. Also, a method for determining the moisture content of the skin, and particularly for diagnosing dry skin in a subject, the method including a step of measuring, in a skin sample obtained from the subject, the expression level of at least one protein selected from ESYT3, USP7, PPL and LCE1C. Further, a method for evaluating the efficacy of a cosmetic treatment for hydrating the skin and to a method for screening candidate cosmetic compounds, both being based on measuring the expression level of the above biomarkers.

    摘要: Disclosed is a method for simulating the rendering of a make-up product on the face of a subject, using a database of reference images including, for each reference individual, images of the face with and without the makeup product. The method includes: acquiring an image of the subject face without makeup; processing the image to extract, for each spatial area of each spatial frequency range of the image, first color feature values of the spatial area; determining, among the database of reference images, reference individuals having, when wearing no makeup, color feature values similar to the first color feature values of the subject; determining, from the first color feature values of the subject, and from color feature values of the reference individuals with and without the makeup product, second color feature values; and generating a modified image of the subject face based on the second color feature values.

    摘要: A solid cosmetic composition including at least one lipophilic gelling agent chosen from sucrose polyesters, at least one fatty substance having a melting point between 25° C. and 55° C., at least one oil, at least one colorant. Also, a stick including the solid cosmetic composition, a method for preparing the solid cosmetic composition and a method for making up the skin, mucous membranes or integuments, including the application of the solid cosmetic composition.
