Abstract
Description
Die vorliegende Erfindung betrifft die Verwendung an sich bekannter Wirkstoffe, zur kos metischen und topischen dermatologischen Hautaufhellung oder zur Verhinderung der Hautbräunung, insbesondere der durch oxidative Proteinaggregation hervorgerufenen Altersflecken.The present invention relates to the use of known active substances, the kos metic and topical dermatological skin whitening or to prevent the Skin tanning, in particular that caused by oxidative protein aggregation Age spots.
In einer bevorzugten Ausführungsform betrifft die vorliegende Erfindung kosmetische und dermatologische Zubereitungen zur Prophylaxe und Behandlung kosmetischer oder dermatologischer Hautveränderungen wie z. B. der unerwünschten Pigmentierung, bei spielsweise lokale Hyper- und Fehlpigmentierungen (beispielsweise Leberflecken, Sommersprossen), aber auch zur rein kosmetischen Aufhellung größerer, dem indivi duellen Hauttyp an sich durchaus angemessen pigmentierter Hautflächen.In a preferred embodiment, the present invention relates to cosmetic and dermatological preparations for the prophylaxis and treatment of cosmetic or Dermatological skin changes such. As the unwanted pigmentation at For example, local hyper- and false pigmentation (for example liver spots, Freckles), but also for purely cosmetic brightening larger, the indivi dueling skin type by itself quite adequately pigmented skin areas.
Für die Pigmentierung der Haut verantwortlich sind zum einen die Melanozyten, welche in der untersten Schicht der Epidermis, dem Stratum basale, neben den Basalzellen als- je nach Hauttyp entweder vereinzelt oder aber mehr oder weniger gehäuft auftretende pigmentbildende Zellen vorzufinden sind.For the pigmentation of the skin are responsible on the one hand, the melanocytes, which in the lowest layer of the epidermis, the stratum basale, in addition to the basal cells depending on the skin type either isolated or more or less frequently occurring pigment-forming cells are found.
Mit zunehmendem Alter treten zum anderen Lipofuscingranula auf, die sich in der Der mis ablagern und zu unregelmäßigen, dunklen Pigmentflecken (Altersflecken) führen. Die Pigmentablagerungen entstehen durch sogenannte "AGE's" (Advanced Glycosyla tion End products), die durch oxidative Prozesse an den Kohlenhydratresten von Protei nen der Haut und anschließende Polymerisation entstehen. On the other hand, lipofuscin granules, which develop in the der mis deposits and lead to irregular, dark pigment spots (age spots). The pigment deposits are formed by so-called "AGEs" (Advanced Glycosyla tion end products) produced by oxidative processes on the carbohydrate residues of Protei NEN of the skin and subsequent polymerization arise.
Probleme mit Hyperpigmentierung der Haut haben vielfältige Ursachen bzw. sind Be gleiterscheinungen vieler biologischer Vorgänge, z. B. UV-Strahlung (z. B. Sommerspros sen, Ephelides), genetische Disposition, Fehlpigmentierung der Haut bei der Wundhei lung bzw. -vernarbung oder der Hautalterung (z. B. Lentigines seniles).Problems with hyperpigmentation of the skin have many causes or are Be gliding phenomena of many biological processes, eg. B. UV radiation (eg., Sommerspros sen, ephelides), genetic disposition, skin pigmentation in wound healing scarring or skin aging (eg Lentigines seniles).
Es sind Wirkstoffe und Zubereitungen bekannt, welche der Hautpigmentierung entge genwirken. Im praktischen Gebrauch sind im wesentlichen Präparate auf der Grundlage von Hydrochinon, welche aber einesteils erst nach mehrwöchiger Anwendung ihre Wir kung zeigen, deren übertrieben lange Anwendung andererseits aus toxikologischen Gründen bedenklich ist. Auch die Inhibierung der Tyrosinase mit Substanzen wie Koji säure, Ascorbinsäure und Azelainsäure sowie deren Derivaten ist geläufig, hat aber kosmetische und dermatologische Nachteile.There are known active ingredients and preparations, which entge the skin pigmentation genwirken. In practical use are essentially based on preparations of hydroquinone, but which in part only after several weeks of use their We On the other hand, their exaggerated use on the other hand is toxicological Reasons is questionable. Also, the inhibition of tyrosinase with substances such as koji Acid, ascorbic acid and azelaic acid and their derivatives is common, but has cosmetic and dermatological disadvantages.
Diesem Übelstande abzuhelfen, war Aufgabe der vorliegenden Erfindung.To remedy this situation was the object of the present invention.
Die Verwendung von Flavonen bzw. Flavonoiden in der Kosmetik bzw. Dermatologie ist an sich bekannt. So beschreibt die DE-OS 44 44 238 Kombinationen von Zimtsäurederi vaten und Flavonglycosiden, beispielsweise α-Glycosylrutin als Antioxidantien und als Wirkstoffe gegen andere Indikationen. In den Patentoffenlegungsschriften JP-Heisei-08/099859, JP-Heisei-07/233046, JP-Heisei-06/321759 sowie EP-357042 wird die Ver wendung gewisser Flavonoide als sogenannte Skin-whitening-Agenzien beschrieben, wobei dies allerdings die großflächige Hautaufhellung betrifft, die einem anderen Mechanismus unterworfen sind, nämlich der Hemmung der Tyrosinaseaktivität bzw. einfach der UV-Absorption.The use of flavones or flavonoids in cosmetics or dermatology is known in itself. Thus, DE-OS 44 44 238 describes combinations of Zimtsäurederi and flavone glycosides, for example α-glycosyl rutin as antioxidants and as Active ingredients against other indications. In the patent publications JP-Heisei-08/099859, JP-Heisei-07/233046, JP-Heisei-06/321759 and EP-357042, the Ver use of certain flavonoids as so-called skin-whitening agents, However, this concerns the large area skin lightening, the other Mechanism, namely the inhibition of tyrosinase activity or simply the UV absorption.
