Abstract
Description
Die vorliegende Erfindung betrifft die Verwendung von 4-Oxoreti nol und dessen Derivaten in kosmetischen Zubereitungen. Ferner betrifft die Erfindung kosmetische Zubereitungen mit einem wirk samen Gehalt an 4-Oxoretinol und dessen Derivaten. Insbesondere betrifft die vorliegende Erfindung kosmetische Zubereitungen zur Prophylaxe gegen Alterungsprozesse in der Haut.The present invention relates to the use of 4-oxo-ethers nol and its derivatives in cosmetic preparations. Further The invention relates to cosmetic preparations with an effective seed content of 4-oxo-retinol and its derivatives. In particular The present invention relates to cosmetic preparations for Prophylaxis against aging processes in the skin.
Die menschliche Haut unterliegt gewissen Alterungsprozessen, die teilweise auf intrinsische Prozesse (chronoaging) und teilweise auf exogene Faktoren (environmental, z. B. photoaging) zurück zuführen sind. Zusätzlich können vorübergehende oder auch an dauernde Veränderungen des Hautbildes auftreten, wie Akne, fettige oder trockene Haut, Keratosen, Rosaceae, lichtempfind liche, entzündliche, erythematöse, allergische oder autoimmun reaktive Reaktionen wie Dermatosen und Photodermatosen.Human skin is subject to certain aging processes partly due to intrinsic processes (chronoaging) and partly back to exogenous factors (environmental, eg photoaging) are to be supplied. In addition, temporary or even can permanent changes in the appearance of the skin, such as acne, oily or dry skin, keratoses, rosaceae, photosensitivity Liche, inflammatory, erythematous, allergic or autoimmune reactive reactions such as dermatoses and photodermatoses.
Zu den exogenen Faktoren zählen insbesondere das Sonnenlicht oder künstliche Strahlungsquellen mit vergleichbarem Spektrum sowie Verbindungen, die durch die Strahlung entstehen können, wie un definierte reaktive Photoprodukte, die auch radikalisch oder ionisch sein können. Zu diesen Faktoren zählen auch Zigaretten rauch und die darin enthaltenen reaktiven Verbindungen wie Ozon, freie Radikale, beispielsweise das Hydroxylradikal, Singulett sauerstoff und andere reaktive Sauerstoff- oder Stickstoffver bindungen, die die natürliche Physiologie oder Morphologie der Haut stören.The exogenous factors include in particular sunlight or artificial radiation sources with a comparable spectrum as well Compounds that can be generated by the radiation, as un defined reactive photoproducts, which also radical or can be ionic. These factors include cigarettes smoke and the reactive compounds contained in it, such as ozone, free radicals, for example the hydroxyl radical, singlet oxygen and other reactive oxygen or nitrogen ver Compounds that have the natural physiology or morphology of Disturb skin.
Durch den Einfluß dieser Faktoren kann es unter anderem zu direk ten Schäden an der DNA der Hautzellen kommen sowie an den Kolla gen-, Elastin- oder Glycosaminoglycanmolekülen der extrazellu lären Matrix, die für die Festigkeit der Haut verantwortlich sind. Darüberhinaus kann es zu einer Beeinflussung der Signal transduktionsketten kommen, an deren Ende die Aktivierung matrix abbauender Enzyme steht. Wichtige Vertreter dieser Enzyme sind die Matrixmetalloproteinasen (MMPs, z. B. Kollagenasen, Gelati nasen, Stromelysine), deren Aktivität zusätzlich durch TIMPs (tissue inhibitor of matrix metalloproteinases) reguliert werden.Due to the influence of these factors, it can, among other things, to direk damage to the DNA of the skin cells and to the collagen gene, elastin or glycosaminoglycan molecules of the extracellu Larian matrix responsible for the firmness of the skin are. In addition, it may affect the signal Transduction chains come at the end of the activation matrix degrading enzymes is. Important representatives of these enzymes are the matrix metalloproteinases (MMPs, eg collagenases, gelati nasal, stromelysin) whose activity is further enhanced by TIMPs (tissue inhibitor of matrix metalloproteinases).
Die Folgen der o. g. Alterungsprozesse sind Verdünnung der Haut, schwächere Verzahnung von Epidermis und Dermis, Reduktion der Zellzahl sowie der versorgenden Blutgefäße. Dabei kommt es zur Ausbildung von feinen Linien und Falten, die Haut wird ledrig und es können Pigmentstörungen auftreten.The consequences of o. G. Aging processes are thinning of the skin, weaker interlocking of epidermis and dermis, reduction of Cell number as well as the supplying blood vessels. It comes to it Formation of fine lines and wrinkles, the skin becomes leathery and it can pigmentation disorders occur.
Die gleichen Faktoren wirken auch auf Haare, wo es ebenfalls zu einer Schädigung kommen kann. Die Haare werden spröde, weniger elastisch und glanzlos. Die Oberflächenstruktur der Haare ist ge schädigt.The same factors also affect hair, where it too damage can occur. The hair becomes brittle, less so elastic and lackluster. The surface structure of the hair is ge damaged.
Kosmetische oder dermatologische Pflegeprodukte mit Eigenschaf ten, die den beschriebenen oder vergleichbaren Prozessen ent gegenwirken oder deren schädliche Folgen mindern oder rückgängig machen sollen, zeichnen sich häufig durch folgende spezifische Eigenschaften aus - radikalfangend, antioxidativ, entzündungs hemmend oder feuchthaltend wirksam. Sie verhindern oder reduzie ren u. a. die Aktivität der matrixabbauenden Enzyme oder regulie ren die Neusynthese von Kollagen, Elastin oder Proteoglycanen.Cosmetic or dermatological care products with properties ent, which correspond to the described or comparable processes counteract or reduce or reverse their harmful consequences are often characterized by the following specific Features off - radical scavenging, antioxidant, inflammatory inhibiting or moisturizing effective. They prevent or reduce ren u. a. the activity of the matrix degrading enzymes or regulie renal synthesis of collagen, elastin or proteoglycans.
Die Verwendung von Retinsäure bzw. Retinoiden zum Schutz gegen die Photoalterung ist bereits vielfach beschrieben (u. a. in EP A-0 230 498, EP-A-0 379 367, EP-A-0 253 393 und US 4,603,146). Allerdings ist durch die hohe Reizwirkung von Retinsäure der therapeutische Effekt stark beeinträchtigt. WO 98/14167 be schreibt die Verwendung von Retinoiden in Hautpflegezubereitungen mit niedrigerem Irritationspotential.The use of retinoic acid or retinoids for protection against photoaging has been described many times (ia in EP-A-0 230 498, EP-A-0 379 367, EP-A-0 253 393 and US 4,603,146). However, due to the high irritant effect of retinoic acid the therapeutic effect severely impaired. WO 98/14167 be writes the use of retinoids in skincare preparations with lower irritation potential.
