Abstract: The present invention relates to the cosmetic, nutraceutical and/or pharmaceutical, notably dermatological, use of a strain of Lactobacillus crispatus and/or of a composition comprising it for maintaining and/or increasing the expression of extracellular matrix molecules of the skin and/or of mucous membranes and notably for maintaining and/or increasing the biomechanical properties of healthy skin and/or healthy mucous membranes, preferentially the firmness and/or elasticity and/or density of healthy skin and/or healthy mucous membranes.

Abstract: The present invention relates to the cosmetic use of a Khaya senegalensis extract, obtained by aqueous extraction, for maintaining and/or increasing the expression of collagen XVIII in the skin and/or the mucosae and/or the scalp and/or the skin appendages, for maintaining and/or increasing the firmness and/or the elasticity of the skin and/or the mucosae and/or the scalp and/or for reducing the visibility of the skin's pores and/or making the skin smoother and/or for limiting and/or reducing perspiration and/or limiting and/or reducing loss of head hair and/or body hair and/or increasing the growth of head hair and/or body hair and/or reducing or limiting sebum production.

Abstract: The present invention relates to a cosmetic method for increasing collagen gene and/or protein expression comprising topically applying an effective amount of an extract of the plant Quassia amara onto skin and/or mucous membranes. The present invention relates as well to a cosmetic method comprising topically applying an effective amount of such an extract for increasing the firmness of skin and/or mucous membranes of an individual in need thereof. The present invention also relates to a method of cosmetic care comprising topically applying a composition comprising an effective amount of the extract of Q. amara onto skin and/or mucous membranes, for increasing the collagen gene and/or protein expression.

Abstract: The invention relates to the stimulation of the synthesis and of the activity of an isoform of lysyl oxidase, and more particularly of the LOXL (lysyl oxidase-like) isoform. The invention relates notably to a method of identifying an active principle which stimulates the formation of elastic fibers. The aim of the invention is mainly to provide such a method of identification so as to provide compositions which enable stimulating the formation of elastic fibers.

Abstract: The invention relates to a novel active ingredient that stimulates the proliferation and/or the activity of fibroblasts and also to its applications in the cosmetic or pharmaceutical, in particular dermatological, field. In particular, the active ingredient according to the invention comprises a combination of at least one Hibiscus Abelmoschus extract and a soy extract containing at least peptides.

Abstract: The present invention concerns a novel agent which is capable of stimulating the expression of LOXL and of increasing quality and functionality of collagen fibres and has anti-oxidizing, anti-elastase, anti-MMP properties as well as its use in producing cosmetic or pharmaceutical compositions, especially dermatological compositions, or food compositions.

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: Use of collagen of aquatic origin for the production of supports for tissue engineering is disclosed. The collagen may be obtained from fish skin, preferably in its native form. Novel tissue engineering supports with a low risk of contamination are produced.
