Abstract
La présente invention concerne un procédé cosmétique de soin et/ou de maquillage des matières kératiniques, en particulier de la peau et/ou des lèvres et notamment de la peau du visage et/ou du cou, comprenant l’application topique sur lesdites matières kératiniques d’une composition cosmétique comprenant un extrait de feuilles de thé noir de l’espèce Camellia sinensis provenant de l’Ile Maurice. The present invention relates to a cosmetic process for the care and/or makeup of keratin materials, in particular of the skin and/or lips and in particular of the skin of the face and/or neck, comprising the topical application to said keratin materials of a cosmetic composition comprising an extract of black tea leaves of the species Camellia sinensis originating from Mauritius.
Description
DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
La présente invention concerne le domaine cosmétique et en particulier l’utilisation cosmétique d’un extrait de thé noir en provenance de l’île Maurice dans un procédé cosmétique de soin et/ou de maquillage des matières kératiniques.The present invention relates to the cosmetics field and in particular to the cosmetic use of a black tea extract from Mauritius in a cosmetic process for caring for and/or making up keratin materials.
ETAT DE LA TECHNIQUESTATE OF THE ART
La peau est la première barrière de protection de l'organisme vis-à-vis de l'environnement. Elle est donc soumise à des facteurs d’origine exogène (ex : rayonnements UV, variations de température, pollution atmosphérique, fumée de cigarette…) ou endogène (ex : hormones…) susceptibles d’induire des signes du vieillissement cutané, que l’on appellera respectivement vieillissement extrinsèque ou vieillissement intrinsèque (ou physiologique), entraînant notamment l’apparition de rides, un teint inhomogène et/ou une perte de sa fermeté, sa souplesse et son élasticité.The skin is the body's first protective barrier against the environment. It is therefore subject to factors of exogenous origin (eg: UV radiation, temperature variations, atmospheric pollution, cigarette smoke, etc.) or endogenous (eg: hormones, etc.) likely to induce signs of skin aging, which the extrinsic aging or intrinsic (or physiological) aging will be called respectively, resulting in particular in the appearance of wrinkles, an uneven complexion and/or a loss of its firmness, its suppleness and its elasticity.
Il existe donc un besoin constant de trouver des agents capables de prévenir et/ou diminuer les signes du vieillissement cutané, notamment de stimuler et/ou favoriser la vitalité et l’énergie cellulaire, pour une peau plus jeune et éclatante.There is therefore a constant need to find agents capable of preventing and/or reducing the signs of skin aging, in particular of stimulating and/or promoting cellular vitality and energy, for younger and radiant skin.
De manière inattendue, la Demanderesse a mis en évidence qu’un extrait de thé noir provenant de l’île Maurice, en particulier obtenu par un procédé permettant d’enrichir sa teneur en petites molécules d’ARNs, et comparativement à un extrait de thé noir provenant d’Inde obtenu selon le même procédé, avait des effets bénéfiques sur la respiration mitochondriale des cellules et la synthèse d’ATP des cellules de la peau, permettant ainsi de favoriser et/ou stimuler la vitalité des cellules cutanées. Les extraits de feuilles de thé décrits dans l’art antérieur sont obtenus avec des solvants organiques et donc riches en polyphénols de type catéchine (WO2006/111666), mais contiennent peu de molécules organiques telles que des sucres, des acides aminés ou encore des oligo-ribonucléotides. L’extrait de thé noir provenant de l’île Maurice utilisé selon l’invention est avantageusement obtenu par un procédé répondant aux critères de naturalité recherchés par le consommateur, et présentent également une bonne stabilité dans le temps et une absence de toxicité.Unexpectedly, the Applicant has demonstrated that an extract of black tea from Mauritius, in particular obtained by a process making it possible to enrich its content in small molecules of RNAs, and compared to an extract of tea black from India obtained using the same process, had beneficial effects on mitochondrial cell respiration and ATP synthesis in skin cells, thus promoting and/or stimulating the vitality of skin cells. The tea leaf extracts described in the prior art are obtained with organic solvents and therefore rich in polyphenols of the catechin type (WO2006/111666), but contain few organic molecules such as sugars, amino acids or even oligos. -ribonucleotides. The black tea extract from Mauritius used according to the invention is advantageously obtained by a process that meets the criteria of naturalness sought by the consumer, and also has good stability over time and an absence of toxicity.
Les effets démontrés dans la présente invention permettent donc d’envisager l’utilisation de cet extrait de thé noir provenant de l’île Maurice pour prévenir et/ou diminuer les signes du vieillissement cutané. L’extrait de thé noir provenant de l’île Maurice est notamment utilisé selon l’invention comme actif cosmétique destiné à favoriser et/ou stimuler la vitalité des cellules cutanées et/ou le renouvellement épidermique, et/ou la desquamation de la peau, et/ou la cohésion des cellules cutanées, et/ou prévenir et/ou diminuer les signes du vieillissement cutané, notamment la perte de fermeté, la perte d’élasticité, la perte de densité, l’apparition de rides et/ou ridules, la sécheresse de la peau, l’altération de la fonction barrière de la peau, l’altération de la souplesse de la peau et/ou l’altération de l’homogénéité ou de l’éclat du teint.The effects demonstrated in the present invention therefore make it possible to consider the use of this black tea extract from Mauritius to prevent and/or reduce the signs of skin aging. The black tea extract from Mauritius is in particular used according to the invention as a cosmetic active ingredient intended to promote and/or stimulate the vitality of skin cells and/or epidermal renewal, and/or desquamation of the skin, and/or cohesion of skin cells, and/or preventing and/or reducing the signs of skin aging, in particular loss of firmness, loss of elasticity, loss of density, appearance of wrinkles and/or fine lines, the dryness of the skin, the alteration of the barrier function of the skin, the alteration of the suppleness of the skin and/or the alteration of the homogeneity or the radiance of the complexion.
Le premier objet de l’invention concerne donc un procédé cosmétique de soin et/ou de maquillage des matières kératiniques, en particulier de la peau et/ou des lèvres et notamment de la peau du visage et/ou du cou, comprenant l’application topique sur lesdites matières kératiniques d’une composition cosmétique comprenant un extrait de feuilles de thé noir de l’espèceCamellia sinensisprovenant de l’Ile Maurice.The first object of the invention therefore relates to a cosmetic process for caring for and/or making up keratin materials, in particular the skin and/or the lips and in particular the skin of the face and/or the neck, comprising the application topical on said keratinous materials of a cosmetic composition comprising an extract of black tea leaves of the species Camellia sinensis originating from Mauritius.
Un autre objet de l’invention porte sur l’utilisation cosmétique d’un extrait de feuilles de thé noir de l’espèceCamellia sinensisprovenant de l’Ile Maurice tel que défini selon l’invention, comme agent actif pour favoriser et/ou stimuler la vitalité des cellules cutanées et/ou le renouvellement épidermique, et/ou la desquamation de la peau, et/ou la cohésion des cellules cutanées, et/ou prévenir et/ou diminuer les signes du vieillissement cutané, notamment la perte de fermeté, la perte d’élasticité, la perte de densité, l’apparition de rides et/ou ridules, la sécheresse de la peau, l’altération de la fonction barrière de la peau, l’altération de la souplesse de la peau et/ou l’altération de l’homogénéité ou de l’éclat du teint.Another object of the invention relates to the cosmetic use of an extract of black tea leaves of the species Camellia sinensis originating from Mauritius as defined according to the invention, as an active agent for promoting and/or stimulate skin cell vitality and/or epidermal renewal, and/or skin desquamation, and/or skin cell cohesion, and/or prevent and/or reduce the signs of skin aging, in particular loss of firmness , loss of elasticity, loss of density, appearance of wrinkles and/or fine lines, dryness of the skin, alteration of the barrier function of the skin, alteration of the suppleness of the skin and/ or alteration of the evenness or radiance of the complexion.
