Abstract: The present invention relates to the use of an active substance that promotes the inhibition of the formation of AGEs, for preparing a composition to prevent and/or combat the reduction in elastic and plastic properties of tissues, and in particular of the skin, for inhibiting the formation of AGEs, or for preventing and/or combating glycation of proteins in the skin. The invention also relates to a method of screening such active substances.

Abstract: The invention relates to the use, as an active ingredient, of at least one substance that promotes the deglycation of AGEs for preparing a composition, especially for limiting the presence of AGEs in a tissue. The invention particularly relates to the use of such a substance for preparing a composition intended to prevent and/or combat a reduction in flexibility and/or plasticity and/or elasticity and/or functionality of a tissue, and/or to prevent and/or combat the ageing of a tissue, by promoting the deglycation of AGEs in the tissue, said tissue preferably being the skin, or the tissue wall of a blood vessel or of an organ.

Abstract: The present invention relates to a novel sebum secretion inhibitor and use thereof for the production of cosmetic and pharmaceutical, notably dermatological, compositions, intended for preventing and/or reducing the secretion of sebum and notably of squalene.

Abstract: The invention relates to active principles which are capable of inducing the conversion of inactive TGFb-Latent into active TGFb. The invention relates in particular to the use of such an extract for the manufacture of a composition for increasing the concentration of active TGFb1 in the skin, notably in the dermis. The present invention also relates to the uses which are derived from said use, as well as to cosmetic or pharmaceutical compositions which comprise said extract.

Abstract: A method for tinting, for coloring skin, or for increasing the tanned appearance of skin comprising the use of an extract of a plant from the family of Compositae or Asteraceae, preferably an extract of chicory (Cichorium intybus L.), and a method of screening a plant for the manufacture of a cosmetic composition for coloring, particularly for tinting, at least one part of skin.

Abstract: A composite product is disclosed as a collagen support comprising at least one porous collagen layer covered on at least one side with an essentially compact collagen membrane consisting either of a collagen film prepared by drying a collagen gel, preferably in air or a gaseous fluid, or of a very highly compressed collagen sponge. At least one of the two layers, i.e. the porous layer and the essentially compact membrane, may comprise normal, genetically modified or malignant living cells originating particularly from young or elderly subjects. This composite product is used as a collagen support for the manufacture of artificial skin intended especially for performing in vitro tests on the efficacy of potentially active substances or for reconstructing damaged areas of skin in vivo.

Abstract: The invention relates to a collagen product containing collagen of marine origin with a low odor. The collagen product includes one or more collagens or derivatives thereof, including hydrolyzates, with a low odor, at least part of the collagen or the derivatives being of marine origin and having been subjected to a deodorization treatment, particularly with an oxidizing substance such as a sulfite, hydrogen peroxide or ozone, at any stage of the manufacture of the collagen product. The invention also makes it possible to improve the mechanical properties and to use this low-odor collagen product in cosmetic or pharmaceutical products.

Abstract: The present invention relates to water-insoluble solid particles, especially pigments, which characteristically are coated with at least one layer of at least one product resulting from the reaction between at least one molecule capable of becoming hydrated in contact with water and at least one lipophilic molecule. It further relates to cosmetic, pharmaceutical and agricultural compositions comprising such particles and to the manufacture and use of said particles.
