Description

The Invention relates to a method for skin moisturization, characterized that a cosmetic preparation is applied to the skin to be treated and then with the help of a rotating or oscillating brush incorporated into the skin to be moisturized or that a cosmetic preparation on a brush is applied, the brush by means of a drive is placed in rotation or oscillation and the treatment to be treated Skin then with the help of rotating or oscillating Brush is treated using the cosmetic preparation contains at least one moisturizer in both process routes.

cosmetic Preparations which after application to the skin moistening To cause the skin there are many. In particular, it is in State of the art widely used, cosmetic preparations with so-called Moisturizers enrich, as these increase the skin's moisture promise.

The Skin-moisturizing performance of the preparations with a single application However, in very dry skin is often not enough to a skin moisturizing to get a longer period. Only a repeated Applying creates relief.

Out EP 1 304 989 is a device for cleaning the skin is known in which using a rotating brush and a washing or exfoliation preparation, the skin can be cleaned. The specialist speaks here of microdermabrasion. The top 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 the person skilled in the art using a device that which has a rotating and / or oscillating brush, the incorporation of cosmetic preparations the moisturizers contained, the skin moisture increased significantly more can be as if the preparation applied with bare fingers becomes.

Under Skin moisturizing is the treatment of the skin with moisturizers to understand. They serve to enrich moisture in the skin and protect against drying out of the skin.

moisturizer For the purposes of the invention, substances are the skin with moisture enrich and protect from drying out. According to the invention suitable Moisturizers are glycerin, urea, hyaluronic acid, panthenol, Propylene glycol, taurine, ceramides, phytosterols, aloe vera extracts, Creatine, creatinine, sodium hyaluronate, polysaccharides, biosaccharides gum-1 (trade name Fucogel), cucumber extracts, butylene glycol, Propylene glycol, methylpropanediol, ethylhexylglycerol, sorbitol, Amino acids (especially glycine, glycine soy, histidine, Tyrosine, tryptophan) and amino acid derivatives and lactic acid and / or lactates, in particular sodium lactate, ethylhexyloxyglycerol, Pyrrolidone.

Furthermore, it is particularly advantageous to use polymeric moisturizers from the group of water-soluble and / or water-swellable and / or water-gellable polysaccharides. Hyaluronic acid, chitosan and / or a fucose-rich polysaccharide, for example, which are filed in the Chemical Abstracts under the registry number 178463-23-5 and z. B. under the name Fucogel ^® 1000 of the company SOLABIA SA is available.

preparations For the purposes of the invention are in particular emulsions, in addition to a Water phase also contain an oil phase. The advantage of Emulsions is significantly better than the slip properties in purely aqueous preparations. The skin is thereby much less irritated (irritated) than in the known cleaning or microabrasion treatment. The with the inventive Method results are not on closer inspection comparable though the eye-level consideration of the treated skin areas does not necessarily show a difference. The invention Procedure affects by its increased hydration on the lower-lying house layers and not like the state the technique on the top dead cell layer. Dar inventive This process shows a longer-lasting effect with regular use in a general Rejuvenation of the skin reflects. A regular microdermabrasion treatment is not feasible due to the strong irritant effect and would lead to persistent injury, because with the removal of dead skin cells a skin's own protective effect would be lost.

The Preparations contain according to the invention except the above-mentioned substances optionally the usual in cosmetics Additives, for example perfume, dyes, antimicrobial Substances, moisturizing agents, complexing and sequestering agents, Pearlescent agents, plant extracts, vitamins, active ingredients, preservatives, Bactericides, pigments that have a coloring effect, Thickener, softening, moisturizing and / or moisturizing Substances, or other common ingredients of a cosmetic or dermatological formulation such as alcohols, polyols, polymers, Foam stabilizers, electrolytes, organic solvents or silicone derivatives.

According to the invention the devices a drive unit and a brush which carries a variety of bristles or nubs that extending from the surface of a carrier plate in extend the space and the carrier plate a connection / coupling to the drive unit. By the drive unit is the Move the brush into rotation or in oscillating motion. In the method according to the invention, the brush wetted with the cosmetic preparation and this afterwards under rotation or oscillation of the brush on the Skin applied or the cosmetic preparation gets out of the skin applied and then with the rotating or oscillating Brush incorporated into the skin.

The Drive unit may have an electric motor, the z. B. by a battery or accumulator is fed. It is also in the sense the invention to use alternative electroless drive units, z. B. spring drives or spring lifts.

in the It is the purpose of the invention to use brushes that are not only bristles of one variety, but different bristles Dimensions and / or hardness mixed or tufts of bristles mixed on different dimensions and / or hardness to arrange the carrier plate.

Especially Advantageously, brushes have proven that 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 between 0.4 chosen to 1.5 cm.

in the In accordance with the invention, it is also in lieu of bristled brushes, Brushes use a variety of fingers wear sprayed elastic bristles. Fingerbesetzt brushes have the advantage of better cleanability, since the fingers are detached are arranged on the support plate. Also, the massage effect of fingers higher than that of bristles.

Prefers the brush is detachable with the drive unit connected, so that the brush is interchangeable. She has the advantage that the brush can be easily disposed of (Single use) or easy to clean separately. in the The purpose of the invention is to rust the brush, in particular Metal-free, to design, so the z. As well as a cleaning in a washing machine and / or dishwasher possible is.

Also The interchangeability of the brush brings the advantage that Depending on the application, brushes with different bristle trimmings / knob trimmings and / or different hardness with the same drive unit can be used.

The Connection of drive unit and brush must be designed this way that the driving forces (rotation or oscillation) of the drive is transmitted to the brush. It is advantageous if the brush with the drive unit is locked. Also conceivable is a connection in the form of a Velcro is formed.

In the 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.

1 shows an example of a brush, comprising a support plate ( 1 ) from which a plurality of bristles ( 2 ) extend the same length parallel to each other in the free space. The bristles are in clusters ( 3 ) from the carrier plate ( 1 ). The individual bristle tufts can be disordered or in geometric order, as in 4 to 6 shown to be arranged. 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.

2 also schematically shows a brush as it is suitable for the inventive method. In this example, not just bristles of a length as in 1 arranged on the support plate, but the Bristles are sections or tufts in short bristles ( 2a ) and long bristles ( 2 B ) divided up.

In the 3 The brush shown has bristles opposite to the one shown in FIG 2 shown brush also has intermediate lengths. Brushes with shorter bristles can be obtained by machining (eg, trimming) brushes that have bristles of only one length.

In 7 is exemplified a brush that contains not only bristles, but also thicker cylindrical or conical fingers ( 5 ) of a deformable elastomer. These fingers are generally thicker than the bristles and act in the process of the invention slightly massaging the application sites. The 8th and 9 illustrate particular embodiments of a mixed, bristles and finger brush having after 7 ,

10 shows an example of a purely of fingers (nubs) existing brush whose nubs were applied by two-component injection molding in a second manufacturing step on a hard carrier plate. These types of brushes have an increased massaging effect whereby the applied preparations can be excellently transported into deeper skin layers. The 11 and 12 illustrate special embodiments of a reiner finger or knob brush made of elastomeric material.

13 schematically shows the structure of an apparatus for carrying out the method according to the invention, comprising a brush 10 and a drive unit 11 , The drive unit is made in the case shown here from a motor 12 , a switch 13 and a power source 14 together, passing through the switch 13 the connection between motor and power source can be made or interrupted.
