Abstract:
The present invention relates to a method for identifying biological markers for characterizing children's skin. The method of the invention thus makes it possible to identify molecular markers that are expressed differently in children's skin than in the skin of adults. The present invention therefore enables the skin to be characterized at the molecular level from birth and the changes thereof with age to be tracked.

Moreover, the invention relates to a method for cosmetic care of the Skin, appendages and mucosae in order to improve the condition or appearance thereof, comprising the administration of one such composition or one such extract.
Abstract:
A method for reducing the formation of and/or treating skin stretchmarks is described. The method is characterized in that a composition is applied to the areas of skin liable to form or comprising stretchmarks, including skin of the thighs, abdomen, and/or breast. The applied composition includes a soya peptide, a tripeptide consisting of the amino acids glycine, histidine, and lysine, and/or mixtures of the soya peptide and tripeptide in a suitable application vehicle. The composition displays good skin tolerance.
Abstract:
The invention relates to a method for the extraction of all unsaponifiable fraction contained in a vegetable oil, an oil originating from a micro-organism or a vegetable butter or in a co-product from the vegetable oil refining industry, such as deodorisation discharge. The method includes at least: A) a step comprising the transformation of the aforementioned oils, butter or co-product from the vegetable oil refining industry or oils originating from micro-organisms into a hydro-alcoholic solution by means of, in particular, a step selected from saponification and esterification steps; B) a step comprising the extraction of the hydro-alcoholic solution in which the fatty fraction is separated from the unsaponitiable fraction by means of liquid/liquid extraction; and C) an optional step comprising the purification of the unsaponiable fraction, selected from the group containing crystallisation and liquid/liquid extraction steps. According to the invention, at least one step from the liquid/liquid extraction steps in step B, the crystallisation steps in step C and the liquid/liquid extraction steps in step C is performed using a first solvent system containing a concentration of solvent selected from among: fluorinated aromatic solvents, particularly trifluorotoluene (BTF) and hexalluorobenzene (BHF); tert-butyl ethers, particularly 2-ethoxy-2-methylpropane, also known as ethyl-tert-butyl-ether (ETU); solvents comprising at least one silicon atom, particularly hexamethyldisiloxane (HMDS) and tertramethylsilane (TMS); methyl-tetrahydrofuran (MeTHF); and mixtures thereof, representing at least 50 vol.-% in relation to the total volume of the solvent system. The invention also relates to the fractions obtained using this method and to compositions containing said fractions.
Abstract:
The invention relates to a medicament which comprises a peptide extract of avocado and which can also comprise a composition containing D-mannoheptulose and/or perseitol, such as a water-soluble extract of avocado sugars, and/or a peptide extract of lupine.
