Description

BESCHREIBUNG DESCRIPTION
Verfahren zur Depigmentierung der HautMethod for depigmenting the skin
Die Erfindung betrifft ein Verfahren zur Depigmentierung, dadurch gekennzeichnet, dass eine kosmetische Zubereitung auf die zu behandelnde Haut appliziert wird und anschließend mit Hilfe einer rotierenden oder oszilierenden Bürste in die aufzuhellende Haut eingearbeitet wird oder dass eine kosmetische Zubereitung auf eine Bürste aufgetragen wird, die Bürste mit Hilfe eines Antriebes in Rotation oder Oszillation versetzt wird und die zu behandelnde Haut anschließend mit Hilfe der rotierenden oder oszilierenden Bürste behandelt wird, wobei die kosmetische Zubereitung in beiden Verfahrenswegen mindestens einen hautaufhellenden Wirkstoff enthält.The invention relates to a process for depigmentation, characterized in that a cosmetic preparation is applied to the skin to be treated and then incorporated by means of a rotating or oszilierenden brush in the brightened skin or that a cosmetic preparation is applied to a brush, the brush is rotated by means of a drive in rotation or oscillation and the skin to be treated is then treated by means of the rotating or oscillating brush, wherein the cosmetic preparation contains in both process routes at least one skin lightening agent.
Kosmetische Zubereitungen die nach Applikation auf die Haut eine Aufhellung (Depigmentierung) der Haut hervorrufen sollen gibt es viele. Insbesondere ist es im Stand der Technik weit verbreitet, kosmetische Zubereitungen mit sogenannten hautaufhellenden Wirkstoffen anzureichern, da diese eine Erhöhung der Hautfeuchte versprechen.Cosmetic preparations that are supposed to cause a whitening (depigmentation) of the skin after application to the skin are many. In particular, it is widely used in the prior art to enrich cosmetic preparations with so-called skin-lightening active ingredients, since these promise an increase in skin moisture.
Die hautaufhellende Leistung der Zubereitungen bei einmaliger Applikation reicht aber bei stark pigmentierter Haut oftmals nicht aus um eine Aufhellung über einen längeren Zeitraum zu erhalten. Nur ein wiederholtes Applizieren schafft hierbei Linderung.However, the skin-lightening performance of the preparations with a single application is often insufficient in heavily pigmented skin to obtain lightening for a longer period of time. Only repeated application creates relief.
Aus EP 1 304 989 ist eine Vorrichtung zur Reinigung der Haut bekannt, bei der mit Hilfe einer rotierenden Bürste und einer Wasch- bzw. Peelingzubereitung die Haut gereinigt werden kann. Der Fachmann spricht hier von Mikrodermabrasion. Dabei werden die o- bersten Schichten der Epidermis abgetragen und die zurückbleibende Haut erscheint jünder und frischer. Eine solche Behandlung stellt jedoch eine erhebliche Belastung für die behandelten Hautareale dar. Insbesondere werden neben den toten Hautzellen auch Hautfett und Wasser entfernt. Für den Fachmann unerwartet war, das unter Verwendung einer Vorrichtung, welche eine rotierende und/oder oszillierende Bürste aufweist, die Einarbeitung von kosmetischen Zubereitungen, die der kosmetischen und/oder dermatologischen Hautaufhellung oder Reduktion von Pigmentflecken dienen, eine erheblich stärkere Hautaufhellungswir- kung und/oder Reduktion von Pigmentflecken hervorrufen, als wenn sie normal mit den Fingern/Händen eingearbeitet wird.From EP 1 304 989 a device for cleaning the skin is known in which the skin can be cleaned with the aid of a rotating brush and a washing or exfoliating preparation. The specialist speaks here of microdermabrasion. In doing so, the uppermost layers of the epidermis are removed and the remaining skin appears younger and fresher. However, such treatment is a significant burden on the treated skin areas. In particular, skin fat and water are removed in addition to the dead skin cells. For a person skilled in the art, using a device which has a rotating and / or oscillating brush was unexpected, the incorporation of cosmetic preparations which serve for cosmetic and / or dermatological skin lightening or reduction of pigmented spots would have a considerably greater skin lightening effect and / or or reduction of pigmented spots, as if it were incorporated normally with the fingers / hands.
Wirkstoffe die eine Depigmentierung und/oder Hautaufhellung bewirken, werden vom Fachmann als Whitening-Wirkstoff bezeichnet.Agents that cause depigmentation and / or skin lightening are referred to by the expert as whitening agent.
Insbesondere sind Zubereitungen vorteilhaft, die mindestens einen Wirkstoff aus der Gruppe Dioic acid (insbesondere Octadecendioic acid), Süßholzextrakt, Vitamin C und Derivate; Flavonoide, Q10, Ubiquinol, Hydroxymatairesinol, 8-Hexadecen-1 ,16- dicarbonsäure, Ursolsäure, Agouti-Peptide, Süßholzwurzelextrakt, Hydrochinon, Grüntee- Extrakt, Arbutin, Biotin, Maulbeerextrakt (Uvae Ursii), Glycyrrhizin, Plazentaextrakt, As- corbylglucoside, Endothelin-Antagonisten aus Kamillenextrakt enthalten. Zubereitungen im Sinne der Erfindung sind insbesondere Emulsionen, die neben einer Wasserphase auch eine Ölphase enthalten. Der Vorteil von Emulsionen ist, das die Gleiteigenschaften erheblich besser sind als bei rein wässrigen Zubereitungen. Die Haut wird dadurch viel weniger gereizt (irritiert) als bei der bekannten Reinigungs- bzw. Mikro- abrassionsbehandlung. Die mit dem erfindungsgemäßen Verfahren erzielten Ergebnisse sind bei genauerer Betrachtung nicht vergleichbar obwohl die augescheinliche betrach- tung der behandelten Hautareale nicht unbedingt einen Unterschied zeigt. Das erfindungsgemäße Verfahren wirkt sich durch seine verstärkte Aufhellung auf die tieferliegenden Hausschichten aus und nicht wie der Stand der Technik auf die oberste tote Zellschicht. Dar erfindungsgemäße Verfahren zeigt dadurch eine länger andauernde Wirkung die sich bei regelmäßiger Anwendung in einer allgemeinen Verjüngung der Haut wiederspiegelt. Eine regelmäßige Mikrodermabrasionsbehandlung ist auf Grund der starken Reizwirkung dagegen nicht durchführbar und würde zu einer anhaltenden Schädigung führen, da mit dem Entfernen der toten Hautzellen eine hauteigene Schutzwirkung verloren ginge.In particular, preparations are advantageous, the at least one active ingredient from the group dioic acid (especially octadecenedioic acid), licorice extract, vitamin C and derivatives; Flavonoids, Q10, ubiquinol, hydroxymatairesinol, 8-hexadecene-1, 16-dicarboxylic acid, ursolic acid, agouti peptides, liquorice root extract, hydroquinone, green tea extract, arbutin, biotin, mulberry extract (Uvae ursii), glycyrrhizin, placental extract, ascorbyl glucosides, Endothelin antagonists from chamomile extract included. Preparations in the context of the invention are, in particular, emulsions which, in addition to a water phase, also contain an oil phase. The advantage of emulsions is that the sliding properties are considerably better than with purely aqueous preparations. The skin is therefore much less irritated (irritated) than in the known cleaning or micro-abrasion treatment. The results obtained with the method according to the invention are not comparable on closer inspection although the eye-clear view of the treated skin areas does not necessarily show a difference. The method according to the invention has an effect on its intensified lightening on the lower-lying building layers and not on the uppermost dead cell layer, as is the case with the prior art. The process according to the invention thereby shows a longer-lasting effect which, with regular use, is reflected in a general rejuvenation of the skin. On the other hand, regular microdermabrasion treatment is impractical due to the strong irritant effect and would lead to persistent damage, since the removal of dead skin cells would result in the loss of a skin's own protective effect.
Die Zubereitungen enthalten gemäß der Erfindung außer den vorgenannten Substanzen gegebenenfalls die in der Kosmetik üblichen Zusatzstoffe, beispielsweise Parfüm, Farbstoffe, antimikrobielle Stoffe, rückfettende Agentien, Kompleκierungs- und Seque- strierungsagentien, Perlglanzagentien, Pflanzenextrakte, Vitamine, Wirkstoffe, Konservierungsmittel, Bakterizide, Pigmente, die eine färbende Wirkung haben, Verdickungsmittel, weichmachende, anfeuchtende und/oder feuchthaltende Substanzen, oder andere übliche Bestandteile einer kosmetischen oder dermatologischen Formulie- rung wie Alkohole, Polyole, Polymere, Schaumstabilisatoren, Elektrolyte, organische Lösemittel oder Silikonderivate.The preparations according to the invention contain, in addition to the abovementioned substances, if appropriate, the customary additives in cosmetics, for example perfume, dyes, antimicrobial substances, lipid-replaceable agents, complexing and sequestering agents. cationic agents, pearlescent agents, plant extracts, vitamins, active substances, preservatives, bactericides, pigments which have a coloring effect, thickeners, softening, moisturizing and / or moisturizing substances, or other customary constituents of a cosmetic or dermatological formulation such as alcohols, polyols, polymers , Foam stabilizers, electrolytes, organic solvents or silicone derivatives.
Erfindungsgemäß weisen die Vorrichtungen eine Antriebseinheit und eine Bürste auf, die eine Vielzahl von Borsten oder Noppen trägt, die sich von der Oberfläche einer Trägerplatte in den Raum erstrecken und die Trägerplatte eine Verbindung/Kupplung zur An- triebseinheit aufweist. Durch die Antriebseinheit wird die Bürste in Rotation oder in oszillierende Bewegungen versetz. Beim erfindungsgemäßen Verfahren wird die Bürste mit der kosmetischen Zubereitung benetzt und diese anschließend unter Rotation der bzw. Oszillation der Bürste auf der Haut appliziert oder die kosmetische Zubereitung wird aus die Haut aufgebracht und anschließend mit der rotierenden bzw. oszillierenden Bürste in die Haut eingearbeitet.According to the invention, the devices comprise a drive unit and a brush which carries a multiplicity of bristles or nubs which extend from the surface of a carrier plate into the space and the carrier plate has a connection / coupling to the drive unit. By the drive unit, the brush is set in rotation or in oscillating movements. In the method according to the invention, the brush is wetted with the cosmetic preparation and this then applied with rotation of the or oscillation of the brush on the skin or the cosmetic preparation is applied from the skin and then incorporated with the rotating or oscillating brush in the skin.
Die Antriebseinheit kann einen Elektromotor aufweisen, der z.B. durch eine Batterie oder Akkumulator gespeist wird. Es ist auch im Sinne der Erfindung alternative stromlose Antriebseinheiten zu verwenden, z.B. Federantriebe oder Federaufzüge.The drive unit may comprise an electric motor, e.g. powered by a battery or accumulator. It is also within the meaning of the invention to use alternative electroless drive units, e.g. Spring drives or spring lifts.
Im Sinne der Erfindung ist es Bürsten zu verwenden, die nicht nur Borsten einer Sorte tragen, sondern Borsten unterschiedlicher Dimensionen und/oder Härte gemischt oder Borstenbüschel unterschiedlicher Dimensionen und/oder Härte gemischt auf der Trägerplatte anzuordnen.For the purposes of the invention, it is to be used brushes that not only bristles of a variety, but bristles of different dimensions and / or hardness mixed or bristle tufts of different dimensions and / or hardness mixed on the support plate to order.
Besonders vorteilhaft haben sich Bürsten erwiesen, die zwischen 1.000 und 35.000, insbesondere 20.000 bis 30.000 Borsten aufweisen, wobei die Borsten eine Faserstärke von 0,045 bis 1 ,2 mm aufweisen. Die Länge der Borsten ist vorteilhafter Weise zwischen 0,4 bis 1 ,5 cm gewählt.Brushes have proven particularly advantageous, which have between 1,000 and 35,000, in particular 20,000 to 30,000 bristles, wherein the bristles have a fiber thickness of 0.045 to 1, 2 mm. The length of the bristles is advantageously chosen between 0.4 to 1, 5 cm.
Im Sinne der Erfindung ist es auch anstelle der borstenbesetzten Bürsten, Bürsten zu verwenden die eine Vielzahl von Fingern aus gespritzten elastischen Borsten tragen. Fingerbesetzte Bürsten haben den Vorteil einer besseren Reinigbarkeit, da die Finger einzelständig auf der Trägerplatte angeordnet sind. Auch ist der Massageeffekt von Fingern höher als der von Borsten. Bevorzugt ist die Bürste lösbar mit der Antriebseinheit verbunden, so das die Bürste austauschbar ist. Die hat den Vorteil, das sich die Bürste einfach entsorgen lässt (Einmalbenutzung) bzw. leicht separat reinigen lässt. Im Sinne der Erfindung ist es, die Bürste rostfrei, insbesondere Metallfrei, auszugestalten, so das z.B. auch eine Reinigung in einer Waschmaschine und/oder Geschirrspüler möglich ist.For the purposes of the invention, it is also in lieu of bristled brushes to use brushes carrying a plurality of fingers of molded elastic bristles. Fingerbesetzte brushes have the advantage of better cleanability, since the fingers are arranged individually on the support plate. Also, the massage effect of fingers is higher than that of bristles. Preferably, the brush is detachably connected to the drive unit, so that the brush is replaceable. This has the advantage that the brush can be easily disposed of (single use) or can be easily cleaned separately. In the context of the invention, the brush stainless, in particular metal-free, to design, so that, for example, a cleaning in a washing machine and / or dishwasher is possible.
Auch bringt die Austauschbarkeit der Bürste den Vorteil, das je nach Anwendungsbereich Bürsten unterschiedlichen Borstenbesatzes/Noppenbesatzes und/oder unterschiedlicher Härte mit der selben Antriebseinheit verwendet werden können.Also, the interchangeability of the brush brings the advantage that can be used with the same drive unit depending on the application brushes different Bristle trim / Noppenbesatzes and / or different hardness.
Die Verbindung von Antriebseinheit und Bürste muss so gestaltet werden, das die An- triebskräfte (Rotation bzw. Oszillation) des Antriebes auf die Bürste übertragen wird. Vorteilhaft ist es wenn die Bürste mit der Antriebseinheit verrastet ist. Denkbar ist auch eine Verbindung die in Form eines Klettverschlusses ausgebildet ist.The connection between the drive unit and the brush must be designed so that the drive forces (rotation or oscillation) of the drive are transferred to the brush. It is advantageous if the brush is locked to the drive unit. It is also conceivable a compound which is designed in the form of a hook and loop fastener.
In den Figuren 1 bis 12 sind einige Bürstengeometrien schematisch wiedergegeben, die sich als besonders vorteilhaft herausgestellt haben. Diese Bespiele sollen sich jedoch nicht limitierend auf die Erfindung auswirken, sondern verdeutlichen, welchen Gestaltungsspielraum es gibt.In the figures 1 to 12 some brush geometries are shown schematically, which have been found to be particularly advantageous. However, these examples are not intended to limit the invention, but to clarify which scope for design exists.
Figur 1 zeigt ein Beispiel für eine Bürste, enthaltend eine Trägerplatte (1 ) von der sich eine Vielzahl von Borsten (2) gleicher Länge parallel zu einander in den freien Raum erstrecken. Die Borsten stehen in Büscheln (3) von der Trägerplatte (1 ) ab. Die einzelnen Borstenbüschel können ungeordnet oder in geometrischer Ordnung, wie in Figur 4 bis 6 gezeigt, angeordnet sein. Im Sinne der Erfindung ist es nicht nur Borsten einer Sorte zu verwenden, sondern Borsten unterschiedlicher Dimensionen und/oder Härte gemischt oder Borstenbüschel unterschiedlicher Dimensionen und/oder Härte gemischt auf der Trägerplatte anzuordnen. Figur 2 zeigt ebenfalls schematisch eine Bürste wie sie für das erfinderische Verfahren geeignet ist. In diesem Beispiel sind nicht nur Borsten einer Länge wie in Figur 1 auf der . Trägerplatte angeordnet, sondern die Borsten sind Abschnittsweise bzw. Büschelweise in kurze Borsten (2a) und lange Borsten (2b) aufgeteilt.Figure 1 shows an example of a brush comprising a support plate (1) from which a plurality of bristles (2) of equal length extending parallel to each other in the free space. The bristles are in clusters (3) from the support plate (1). The individual bristle tufts can be arranged in a random or geometrical arrangement, as shown in FIGS. 4 to 6. For the purposes of the invention, it is not only to use bristles of one kind, but to mix bristles of different dimensions and / or hardness or to arrange bristle tufts of different dimensions and / or hardness mixed on the carrier plate. Figure 2 also shows schematically a brush as it is suitable for the inventive method. In this example, not only are bristles of a length as in FIG. Instead, the bristles are divided into short bristles (2a) and long bristles (2b) in sections or tufts.
Die in Figur 3 gezeigte Bürste weist Borsten auf, die gegenüber der in Figur 2 gezeigten bürste auch Zwischenlängen aufweist. Bürsten mit kürzeren Borsten können durch Bearbeitung (z.B. beschneiden) von Bürsten erhalten werden, die Borsten nur einer Länge aufweisen. In Figur 7 ist beispielhaft eine Bürste wiedergegeben, die nicht nur Borsten enthält, sondern auch dickere zylindrische oder kegelförmige Finger (5) aus einen verformbarem E- lastomer aufweisen. Diese Finger sind im Allgemeinen dicker als die Borsten und wirken beim erfindungsgemäßen Verfahren leicht massierend auf die Applikationsstellen. Die Figuren 8 und 9 illustrieren besondere Ausgestaltungen einer gemischten, Borsten und Finger aufweisenden Bürste nach Figur 7.The brush shown in FIG. 3 has bristles which also have intermediate lengths with respect to the brush shown in FIG.
