Description
L’invention se rapporte à une composition, utile en dermatologie et/ou en cosmétique, permettant de prévenir, réduire ou éliminer les imperfections cutanées et de traiter des troubles cutanés tels que l’acné.The invention relates to a composition, useful in dermatology and/or in cosmetics, making it possible to prevent, reduce or eliminate skin imperfections and to treat skin disorders such as acne.
La séborrhée est une condition biologique, et l’hyper séborrhée et l’hyperkératinisation sont des troubles biologiques de la peau, qui mènent tous les trois à l’apparition d’imperfections cutanées.Seborrhoea is a biological condition, and hyperseborrhoea and hyperkeratinization are biological skin disorders, all three of which lead to the appearance of skin imperfections.
La séborrhée et l’hyper séborrhée concernent la sécrétion de sébum. Un fonctionnement biologique normal de la peau nécessite la sécrétion de sébum par les glandes sébacées situées dans le derme. Le sébum forme un film lipidique à la surface de l’épiderme et des poils. Ce film protège la peau contre le dessèchement, lubrifie le poil, et a un rôle protecteur en favorisant les microorganismes anaérobies et lipophiles : on parle de séborrhée. La sécrétion de sébum peut devenir excessive et entraîner l’apparition d’imperfections cutanées : on parle d’hyper séborrhée. Les imperfections cutanées résultant de la séborrhée sont une peau grasse, voire luisante et brillante, des pores dilatés, un grain de peau épais, des rougeurs.Seborrhoea and hyper seborrhoea concern the secretion of sebum. Normal biological functioning of the skin requires the secretion of sebum by the sebaceous glands located in the dermis. Sebum forms a lipid film on the surface of the epidermis and hair. This film protects the skin against drying out, lubricates the hair, and has a protective role by promoting anaerobic and lipophilic microorganisms: we speak of seborrhea. Sebum secretion can become excessive and lead to the appearance of skin imperfections: this is called hyper seborrhea. Skin imperfections resulting from seborrhea are oily, even shiny and shiny skin, dilated pores, thick skin texture, redness.
L’hyperkératinisation est un trouble biologique qui induit aussi des imperfections cutanées. Généralement induite par les hormones androgènes, elle consiste en une augmentation de la synthèse des cellules cornées. Les imperfections cutanées résultant de l’hyperkératinisation sont une perte d’éclat du teint, et une peau terne.Hyperkeratinization is a biological disorder that also induces skin imperfections. Generally induced by androgen hormones, it consists of an increase in the synthesis of horny cells. Skin imperfections resulting from hyperkeratinization are a loss of complexion radiance and dull skin.
En plus des imperfections cutanées évoquées précédemment, l’hyper séborrhée et l’hyperkératinisation peuvent provoquer, indépendamment ou ensemble simultanément des pathologies comme l’acné. L’acné est une maladie inflammatoire chronique du follicule pilo sébacé qui atteint la plupart des adolescents et des adultes. La pathologie est variée dans sa présentation et sa sévérité. L’élément commun réside dans la rétention sébacée qui se traduit cliniquement par des lésions élémentaires spécifiques.In addition to the skin imperfections mentioned above, hyper seborrhea and hyperkeratinization can cause, independently or together simultaneously, pathologies such as acne. Acne is a chronic inflammatory disease of the pilo-sebaceous follicle that affects most adolescents and adults. The pathology is varied in its presentation and severity. The common element lies in the sebaceous retention which clinically results in specific elementary lesions.
Ainsi, l’hyperkératinisation et l’hyper séborrhée provoquent, ensemble ou séparément, l’obstruction des follicules piligères, c’est-à-dire des pores de la peau. Cette obstruction est visible par l’apparition de troubles cutanés appelés « comédons », soit ouverts, aussi appelés « point noir », quand le sébum reste exposé à l’air et noircit du fait de l’oxydation, soit fermés, aussi appelés « point blanc », quand le sébum n’est plus exposé à l’air (i.e. quand l’obstruction est due l’hyperkératinisation).Thus, hyperkeratinization and hyper seborrhea cause, together or separately, the obstruction of the piligerous follicles, that is to say the pores of the skin. This obstruction is visible by the appearance of skin disorders called "comedones", either open, also called "blackhead", when the sebum remains exposed to the air and blackens due to oxidation, or closed, also called " white point", when the sebum is no longer exposed to the air (i.e. when the obstruction is due to hyperkeratinization).
Dans ces comédons, la prolifération de bactéries du genrePropionobacterium spp., notammentPropionobacterium acnes, induit une réaction inflammatoire causant une rougeur et une gêne douloureuse au touché. La prolifération bactérienne peut entrainer des lésions inflammatoires superficielles (papules et pustules) et profondes (nodules).In these comedones, the proliferation of bacteria of the genus Propionobacterium spp ., in particular Propionobacterium acnes , induces an inflammatory reaction causing redness and painful discomfort when touched. Bacterial proliferation can lead to superficial (papules and pustules) and deep (nodules) inflammatory lesions.
Ainsi, l’acné est une affection du follicule pilo-sébacé dans laquelle intervient quatre facteurs qui sont étroitement liés : une hyper séborrhée, une hyperkératinisation, la prolifération dePropionobacterium acneset une inflammation.Thus, acne is a condition of the pilosebaceous follicle in which four closely related factors intervene: hyper seborrhoea, hyperkeratinization, proliferation of Propionobacterium acnes and inflammation.
Dans l’état de la technique, diverses solutions ont été proposées pour réduire la sécrétion excessive de sébum au niveau de la peau. Des compositions comprenant des agents abrasifs ou des agents astringents ont été utilisées. En effet, pour essayer de résoudre le problème d’hyper séborrhée, une action de régulation de la sécrétion sébacée, une action « purifiante » d’absorption du sébum et une action astringente sont recherchées.In the state of the art, various solutions have been proposed for reducing the excessive secretion of sebum in the skin. Compositions comprising abrasive agents or astringent agents have been used. Indeed, to try to solve the problem of hyper seborrhoea, an action of regulation of the sebaceous secretion, a "purifying" action of absorption of the sebum and an astringent action are sought.
Le document WO 2015/106175, décrit l’acide succinique comme ayant un effet bactéricide sur Propionobacterium spp. L’effet kératolytique de l’acide succinique est aussi connu, si bien qu’on lui attribue une propriété de « peeling » de la peau.Document WO 2015/106175 describes succinic acid as having a bactericidal effect on Propionobacterium spp. The keratolytic effect of succinic acid is also known, so much so that it is attributed a skin "peeling" property.
Problème techniqueTechnical problem
Beaucoup de produits restent cependant déceptifs, la plupart en raison d’une action décapante du produit, induisant un effet rebond par excitation de la glande sébacée et augmentant ainsi la production de sébum.However, many products remain disappointing, most of them due to a stripping action of the product, inducing a rebound effect by excitation of the sebaceous gland and thus increasing the production of sebum.
Ainsi, la présente invention a pour objet une composition cosmétique ou dermatologique de soin des matières kératiniques, comprenant, dans un milieu physiologiquement acceptable, au moins acide organique choisi parmi les acides dicarboxyliques linéaires ou branchés, dont la chaîne carbonée est constituée de 2 à 10 atomes de carbones, préférentiellement de 3 à 5 atomes de carbones, et tout préférentiellement de 4 atomes de carbones.Thus, the subject of the present invention is a cosmetic or dermatological composition for caring for keratin materials, comprising, in a physiologically acceptable medium, at least one organic acid chosen from linear or branched dicarboxylic acids, the carbon chain of which consists of 2 to 10 carbon atoms, preferably from 3 to 5 carbon atoms, and very preferably from 4 carbon atoms.
La présente invention a également pour objet un procédé de soin des matières kératiniques, en particulier la peau, consistant à appliquer sur lesdites matières kératiniques, en particulier la peau, une composition cosmétique selon l’invention.A subject of the present invention is also a process for caring for keratin materials, in particular the skin, consisting in applying to said keratin materials, in particular the skin, a cosmetic composition according to the invention.
L’invention a également pour objet l’utilisation cosmétique non thérapeutique d’une composition cosmétique selon l’invention pour prévenir, réduire ou éliminer les imperfections cutanées telles que la peau grasse, la peau luisante, la peau brillante, les pores dilatés, un grain de peau épais, des rougeurs, des démangeaisons, la perte d’éclat, la peau terne.A subject of the invention is also the non-therapeutic cosmetic use of a cosmetic composition according to the invention for preventing, reducing or eliminating skin imperfections such as oily skin, shiny skin, shiny skin, dilated pores, thick skin texture, redness, itching, loss of radiance, dull skin.
L’invention concerne également une composition dermatologique selon l’invention pour son utilisation dans le traitement des troubles cutanés tels que l’acné.The invention also relates to a dermatological composition according to the invention for its use in the treatment of skin disorders such as acne.
