Method of filling skin imperfections

The invention relates to a method of filling imperfections such as recessed areas, in particular of the skin, with improved resistance that consists in applying, advantageously using an applicator suitable for the areas to be treated, an anhydrous cosmetic composition containing at least one adhesive compound, one liquid fatty phase and one pulverulent phase. The invention also relates to a particular cosmetic composition for making up and/or non-therapeutically treating the skin. The term "filling" is intended to mean, not simply depositing a layer which moulds the profile of the recessed areas and which fills only the bottom thereof, but, on the contrary, filling at least a large part (typically 50% or more), preferably to the brim, of the recessed area to be masked, in particular wrinkles, pores or scars.

Preferably, the deposit of filling product is limited so as not to spread beyond the recessed area.

The presence of skin imperfections such as particular recessed areas of the skin on the face, such as pores, wrinkles or scars, poses aesthetic problems which may be difficult to live with.

Various means exist for attempting to solve the problem of masking these imperfections. It is possible, for example to use cosmetic compositions that bring about an optical blurring or else a tightening effect. However, these two solutions are only effective on slight imperfections such as enlarged pores, and the durability of the effect is generally very short. It is also possible to use cosmetic active agents. This solution only leads to a result that is more or less satisfactory over the long term and unfortunately does not apply to scars, but only to minor blemishes. It is also possible to resort to plastic surgery to repair these imperfections on the skin. However, this severe and expensive method has many contraindications, presents certain risks and, in certain cases, does not guarantee results for all that.

One advantageous solution appears to consist in covering the skin with a complete layer (without being limited to the sole recessed area to be masked), a little bit like film industry skin camouflage. However, the result is uncomfortable, especially in the event of perspiration, and often the thick layer does not stay in place over time. In addition, the aesthetic appearance of the skin is lost. Finally, this technique poses the problem of demarcations, in particular for compositions comprising a high content of colorants, such as those described in Application EP 2 168 565. On the contrary, such compositions make surface imperfections more visible after application. Indeed, unless all the visible skin is covered, an outside observer quickly notices that certain parts of the skin do not have the same appearance as the rest. It is therefore necessary, if an aesthetic result is desired, to treat the thick layer and also the skin that is not covered in order to limit the demarcation effects. This technique is furthermore contraindicated for sensitive skin.

There therefore remains the need to have a composition that can be applied in a single action to the keratin materials and that makes it possible to lastingly, effectively and comfortably fill the recessed area, advantageously with no demarcation effect.

We have found that it is possible to locally apply an anhydrous cosmetic composition containing at least one adhesive compound, one liquid fatty phase and one pulverulent phase. This discontinuous application gives an effective, lasting and comfortable filling. The application can be carried out with the fingers or preferably with a suitable applicator. Surprisingly, the composition is not tacky despite the presence of the adhesive compound. It has a high stiffness which, combined with its adhesive nature, makes it possible to stay in place throughout the day.

It may also flow above a certain yield stress, which enables an easy application. The remarkable and unexpected properties obtained with the composition according to the invention are especially due, on the one hand, to its rheological behaviour and, on the other hand, to its chemical composition.

Rheological properties

The composition according to the present invention is advantageously in the form of a paste.

The term "paste" is here intended to mean a product or a composition for which the viscosity can be measured, as opposed to the solid structure of a wand or stick, the viscosity of which cannot be measured.

The products or compositions used for implementing the method according to the invention advantageously have characteristic rheological parameters comprising the flow point, the elastic modulus and the viscosity.

The flow point or destructuring yield stress τθ of the filling product is defined as being the pressure required to cause a macroscopic flow of the product; it can be determined by performing a stress sweep, for example using a Haake CS150 controlled stress rheometer at a temperature of 25°C in striated plate-plate geometry. The destructuring yield stress, also referred to as the flow point, will advantageously be between 10 and 1000 Pa, preferably between 50 and 800 Pa.

Moreover, the elastic modulus of the filling product can be measured for a stress frequency of 1 Hz, in the "linear viscoelasticity" zone defined by the fact that the stress applied during the measurement is lower than the destructuring yield stress of the composition.

The composition according to the invention may thus be characterized by its elastic modulus in the linear viscoelasticity zone. This modulus, measured at 25°C with a stress frequency of 1 Hz will advantageously range from 10 000 to 500 000 Pa, preferably from 20 000 to 200 000 Pa.

With regard to their viscosity, the compositions according to the invention exhibit a deformability that makes it possible to carry out modelling of the skin, in particular of the facial skin, which is therefore effective for reducing the cutaneous microrelief thereof.

The viscosity is measured at 25°C with a Haake Rheostress RS 150 instrument in striated plate-plate configuration under an increasing applied stress. The viscosity of the filling product used for implementing the method according to the invention is preferably between 10 000 and 1 000 000 Pa.s, preferably between 20 000 and 500 000 Pa.s for an applied stress of 100 Pa.

These conditions are advantageous for obtaining a composition which spreads well, especially with an applicator, and which is stiff enough to stay in place well over time.

The present invention therefore relates to a cosmetic method for making up and/or non- therapeutically treating skin imperfections, ie recessed areas of the skin, comprising the application at least to said areas, of at least one anhydrous composition comprising, in a physiologically acceptable medium:

(i) at least one adhesive compound;

(ii) at least one pulverulent phase containing less than 20% by weight of colorants relative to the total weight of the composition; and

(iii) at least one liquid fatty phase,

the weight ratio of the liquid fatty phase to the pulverulent phase advantageously being between 0.3 and 5. Examples of adhesive compounds are described below.

According to one particular embodiment of the method according to the invention, the composition is applied to the skin using an applicator, such as an applicator comprising at least one tip made of silicone, of foam or of flocked fabric, especially of flat, cylinder of revolution or cone shape.

The method of the invention is especially intended to mask pores, wrinkles or scars, such as acne scars.

The invention also relates to an anhydrous cosmetic composition for topical application to the skin comprising, in a physiologically acceptable medium:

(i) at least one tackifying resin;

(ii) at least one pulverulent phase; and

(iii) at least one liquid fatty phase comprising at least one non-volatile hydrocarbon-based oil,

the weight ratio of the liquid fatty phase to the pulverulent phase advantageously being between 0.3 and 5.

According to one particular embodiment, the pulverulent phase contains less than 20% by weight of colorants relative to the total weight of said composition.

According to one preferred embodiment, the tackifying resin is chosen from indene hydrocarbon-based resins, in particular from hydrogenated indene/methylstyrene/styrene copolymers.

The invention also relates to a cosmetic packaging and application assembly, for application to keratin materials, especially the skin, comprising at least:

(a) a packaging device comprising at least one composition as defined in the invention; and

(b) an applicator.

Adhesive compound

An 'adhesive compound' according to the invention means in particular a compound having an adhesion energy on keratin materials, in particular the skin, which is superior to the cohesion energy of the compound itself. The adhesion energy relates to the interaction strength between the compound and a substrate (keratin material), whereas the cohesion energy relates to the interaction forces inside the compound itself.

We may mention in particular the publication J.N.Israelachvili, Intermolecular and Surface Forces (Academic Press, New Tork, 1985), chap 15.

The adhesive compound is especially chosen from adhesive polymers and resins.

In particular, the adhesive compound is chosen from tackifying resins, silicone resins and copolymers of silicone resins, silicone copolymers especially acrylate/silicone copolymers and ^v ' ⁿ Y' polymers comprising at least one carbosiloxane dendrimer-derived unit _j polycondensates (polyesters), polyalkene-based supramolecular polymers, and mixtures thereof.

According to one particular embodiment, the composition according to the invention comprises at least one tackifying resin.

According to one particular embodiment, the composition according to the invention comprises at least one silicone copolymer especially acrylate/silicone copolymers and vinyl polymers comprising at least one carbosiloxane dendrimer-derived unit.

These ingredients make it possible to improve the adhesion of the cosmetic composition to the skin without obtaining a significant tacky effect.

The adhesive compound is generally present in the composition in a content ranging from 1 % to 30% by weight, preferably from 3% to 20% by weight and preferably from 5% to 15% by weight (of active material) relative to the total weight of said composition.

Tackifying resins

Such a resin generally has a number-average molecular weight of less than or equal to 10 000 g/mol, especially ranging from 250 to 10 000 g/mol, preferably less than or equal to 5000 g/mol, especially ranging from 250 to 5000 g/mol, better still less than or equal to 2000 g/mol, especially ranging from 250 to 2000 g/mol and better still less than or equal to 1000 g/mol, especially ranging from 250 to 1000 g/mol. The number-average molecular weights (Mn) are determined by gel permeation liquid chromatography (THF solvent, calibration curve established with linear polystyrene standards, refractometric detector).

This resin is advantageously a resin as described in the Handbook of Pressure Sensitive Adhesive Technology, edited by Donatas Satas, 3rd ed., 1989, p. 609-619.

It is advantageously chosen from rosin, rosin derivatives, hydrocarbon-based resins and mixtures thereof.

• Rosin is a mixture predominantly comprising organic acids known as rosin acids (mainly acids of abietic type and of pimaric type).

There are three types of rosin: rosin ("gum rosin") obtained by incision on live trees, wood rosin, which is extracted from pine wood or stumps, and tall oil ("tall oil rosin"), which is obtained from a by-product originating from the production of paper.

The rosin derivatives may be derived in particular from the polymerization, hydrogenation and/or esterification (for example with polyhydric alcohols such as ethylene glycol, glycerol or pentaerythritol) of rosin acids. Examples that may be mentioned include the rosin esters sold under the reference Foral 85, Pentalyn H and Staybelite Ester 10 by the company Hercules; Sylvatac 95 and Zonester 85 by the company Arizona Chemical, or Unirez 3013 by the company Union Camp.

Silicone resin

More generally, the term "resin" is understood to mean a compound which has a three-dimensional structure. They are referred to as "silicone resins" or "siloxane resins". Thus, within the meaning of the present invention, a polydimethylsiloxane is not a silicone resin.

The nomenclature of silicone resins (also referred to as siloxane resins) is known under the name "MDTQ", the resin being described as a function of the various siloxane monomer units it comprises, each of the letters M, D, T and Q characterizing a type of unit.

The letter "M" represents the monofunctional unit of formula R1 R2R3SiOi _/2 , the silicon atom being bonded to only one oxygen atom in the polymer comprising this unit.

The letter "D" means a difunctional unit R1 R2Si0 ₂ /2 in which the silicon atom is bonded to two oxygen atoms.

The letter T represents a trifunctional unit of formula R1 Si0 _3/2 .

Such resins are described, for example, in "Encyclopedia of Polymer Science and Engineering, vol. 15, John and Wiley and Sons, New York, (1989), p. 265-270, and US 2,676,182, US 3,627,851 , US 3,772,247, US 5,248,739 or else US 5,082,706, US 5,319,040, US 5,302, 685 and US 4,935,484.

In the M, D and T units defined previously R, namely R1 , R2 and R3, represents a hydrocarbon-based radical (especially alkyl) having from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or else a hydroxyl group.

Finally, the letter "Q" means a tetrafunctional unit Si0 _4/2 in which the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the rest of the polymer.

As silicone resins that may be used in the compositions according to the invention, use may be made, for example, of silicone resins of MQ type, of T type or of MQT type.

MQ resins: As examples of silicone resins of MQ type, mention may be made of the alkyl siloxysilicates of formula [(R1 ) ₃ SiOi/2] _x (Si04/2) _y (MQ units) in which x and y are integers ranging from 50 to 80, and such that the group R1 represents a radical as defined previously, and is preferably an alkyl group containing from 1 to 8 carbon atoms, or a hydroxyl group, preferably a methyl group.

As examples of solid silicone resins of MQ type of trimethyl siloxysilicate type, mention may be made of those sold under the reference SR1000 by the company General Electric, under the reference TMS 803 by the company Wacker, or under the name KF-7312J by the company Shin-Etsu or DC 749 or DC 593 by the company Dow Corning.

As silicone resins comprising MQ siloxysilicate units, mention may also be made of phenylalkyl siloxysilicate resins, such as phenylpropyldimethyl siloxysilicate (Silshine 151 sold by the company General Electric). The preparation of such resins is described especially in patent US 5 817 302.

T resins:

Examples of silicone resins of T type that may be mentioned include the polysilsesquioxanes of formula (RSi0 ₃ / ₂ )x (T units) in which x is greater than 100 and such that the group R is an alkyl group containing from 1 to 10 carbon atoms, said polysilsesquioxanes also possibly comprising Si-OH end groups.

Polymethylsilsesquioxane resins that may preferably be used are those in which R represents a methyl group, for instance those sold:

- by the company Wacker under the reference Resin MK, such as Belsil PMS

MK: polymer comprising CH ₃ Si0 ₃ /2 repeating units (T units), which may also comprise up to 1 % by weight of (CH ₃ ) ₃ Si0 ₂ /2 units (D units) and having an average molecular weight of about 10 000 g/mol, or

- by the company Shin-Etsu under the reference KR220L, which are composed of T units of formula CH ₃ Si0 _3/2 and have Si-OH (silanol) end groups, under the reference KR242A, which comprise 98% of T units and 2% of dimethyl D units and have

Si-OH end groups, or alternatively under the reference KR251 comprising 88% of T units and 12% of dimethyl D units and have Si-OH end groups.

MQT resins:

Resins comprising MQT units that are especially known are those mentioned in document US 5 1 10 890.

A preferred form of resins of MQT type are MQT-propyl (also known as MQTpr) resins. Such resins that may be used in the compositions according to the invention are especially the resins described and prepared in patent application WO 2005/075542.

Advantageously, the A/B weight ratio is between 95/5 and 15/85. Preferably, the A/B ratio is less than or equal to 70/30. These preferred ratios have proved to make comfortable depositions possible.

Silicone resin copolymers The silicone copolymer defined according to the invention is derived from the reaction between a silicone resin and a silicone fluid.

Copolymers of this kind are described in, for example, "Silicone Pressure Sensitive Adhesives", Sobieski and Tangney, Handbook of Pressure Sensitive Adhesive Technology (D. Satas Ed.), Van Nostrand Reinhold, New York.

In the copolymer, the silicone resin is present at a content between 45 and 75% (relative to the total weight of silicone) and the silicone fluid is present at a content between 25 and 55%, with the sum of the percentages of silicone resin and silicone fluid which is equal to 100. Preferably, the silicone resin is present at a content between 55 and 65% (relative to the total weight of silicone) and the silicone fluid is present at a content between 35 and 45%, with the sum of the percentages of silicone resin and silicone fluid which is equal to 100.

Triorganosilyl groups that can be used to form the silicone resin may be trimethylsilyl, triethylsilyl, methylmethylpropylsilyl or dimethylvinylsilyl units and mixtures thereof. The trimethylsilyl group is the preferred group within the context of the invention.

In the present patent application, the term "polydimethylsiloxanes" (also known as organopolysiloxanes and abbreviated as PDMS) denotes, in accordance with what is generally accepted, any organosilicon polymer or oligomer of linear structure, of variable molecular weight, obtained by polymerization and/or polycondensation of suitably functionalized silanes, and consisting essentially of a repetition of main units in which the silicon atoms are linked together via oxygen atoms (siloxane bond≡Si-0-Si≡), comprising trimethyl radicals directly linked via a carbon atom to said silicon atoms. The PDMS chains that may be used to obtain the copolymer used according to the invention comprise at least one polymerizable radical group, preferably located on at least one of the ends of the chain, i.e. the PDMS may contain, for example, a polymerizable radical group on the two ends of the chain or one polymerizable radical group on one end of the chain and one trimethylsilyl end group on the other end of the chain. The polymerizable radical group may especially be an acrylic or methacrylic group, in particular a group CH2 = CR1 - CO - O - R2, in which R1 represents a hydrogen or a methyl group, and R2 represents -CH2-, -(CH2)n- with n = 3, 5, 8 or 10, -CH2-CH(CH3)-CH2- , -CH2-CH2-0- CH2-CH2-, -CH2-CH2-0-CH2-CH2-CH(CH3)-CH2-, -CH2-CH2-0-CH2 CH2-0-CH2- CH2-CH2-.

The copolymers obtained generally have a molecular weight ranging from about 3000 to 200 000 and preferably from about 5000 to 100 000.

The copolymer used in the composition of the invention may be in its native form or in dispersed form in a solvent such as lower alcohols containing from 2 to 8 carbon atoms, for instance isopropyl alcohol, or oils, for instance volatile silicone oils (for example cyclopentasiloxane).

The vinyl polymer used according to the invention especially has a backbone and at least one side chain, which comprises a carbosiloxane dendrimer-derived unit having a carbosiloxane dendrimer structure.

Vinyl polymers comprising at least one carbosiloxane dendrimer unit as described in patent applications WO 03/045 337 and EP 963 751 by the company Dow Corning may be used in particular.

The term "carbosiloxane dendrimer structure" in the context of the present invention represents a molecular structure with branched groups of high molecular weights, said structure having high regularity in the radial direction starting from the bond to the backbone. Such carbosiloxane dendrimer structures are described in the form of a highly branched siloxane-silylalkylene copolymer in the laid-open Japanese patent application Kokai 9-171 154.

A cosmetic composition in accordance with the invention may incorporate at least one colorant chosen from organic or mineral colorants, especially such as the pigments or nacres conventionally used in cosmetic compositions, liposoluble or water- soluble colorant and mixtures thereof.

The term "pigments" should be understood as meaning white or coloured, mineral or organic particles, which are insoluble in an aqueous solution and which are intended to colour and/or opacify the resulting film. The pigments may be present in a proportion of from 0.1 % to 20% by weight and especially from 0.5% to 10% by weight relative to the total weight of the cosmetic composition.

As mineral pigments that may be used in the invention, mention may be made of titanium oxide, zirconium oxide or cerium oxide, and also zinc oxide, iron oxide or chromium oxide, ferric blue, manganese violet, ultramarine blue and chromium hydrate.

The colorant may also comprise a pigment having a structure that may be, for example, of silica microsphere type containing iron oxide. An example of a pigment having this structure is the product sold by the company Miyoshi under the reference PC Ball PC-LL-100 P, this pigment consisting of silica microspheres containing yellow iron oxide.

The liposoluble colorants are, for example, Sudan Red, DC Red 17, DC Green 6, β-carotene, soybean oil, Sudan Brown, DC Yellow 1 1 , DC Violet 2, DC Orange 5 and quinoline yellow. The water-soluble colorants are, for example, beetroot juice and caramel.

The colorants may be present in a proportion of from 0.1 % to 20% by weight and especially from 0.5% to 10% by weight relative to the total weight of the cosmetic composition.

According to one particular embodiment, the composition of the invention comprises less than 20% by weight, in particular less than 15% by weight, or even less than 10% by weight of colorants, relative to the total weight of the composition, so as to colour it without opacifying it.

According to another particular embodiment, the composition will be free of colorant in order to be as transparent as possible.

Fatty phase

The composition contains at least one liquid fatty phase. This liquid fatty phase is used to transport the adhesive compound. The liquid fatty phase in the composition is present in a content generally ranging from 20% to 70% by weight, preferably from 25% to 60% by weight and better still from 30% to 50% by weight relative to the total weight of said composition.

The weight ratio between liquid fatty phase and pulverulent phase will advantageously range from 0.3 to 5, preferably from 0.5 to 3, preferably from 0.6 to 2.5, or even from 0.7 to 2. According to one particular embodiment, the weight ratio between liquid fatty phase and pulverulent phase will range from 0.9 to 1 .5, in particular from 0.9 to 1 .2, and especially 1 . Indeed, too high a weight ratio may result in a composition that is too liquid and which is applied as too thin a layer; conversely, too low a weight ratio may result in a composition that is too friable, or even pulverulent.

According to one particular embodiment, the composition may also contain at least one wax having an initial melting point greater than or equal to 50°C, and better still at least one wax for which the initial melting point is greater than or equal to 65°C.

The expression "initial melting point" is understood in the present application to mean the temperature at which a wax begins to melt. This temperature can be determined by DTA (differential thermal analysis) which makes it possible to obtain the thermogram (or melting curve) of the wax in question. The initial melting point corresponds to the temperature at which a significant change of gradient can be observed in the thermogram. The melting point itself represents the minimum point of said thermogram.

More specifically, such a wax may be chosen from carnauba wax, certain polyethylene waxes and certain microcrystalline waxes such as those sold under the name Microwax ^® , in particular that sold under the name Microwax HW ^® , by the company Paramelt.

It may make it possible to thicken and stabilize the composition according to the invention. The amount of wax may generally range from 0.1 % to 25% by weight, preferably from 1 % to 15% by weight and preferably from 2% to 12% by weight relative to the total weight of said composition.

The compositions of the invention may also comprise at least one alkyldimethicone, alkoxydimethicone or phenyldimethicone such as, for example, the product sold under the name "Abil wax 2440" by the company Goldschmidt.

Thus, the composition according to the invention advantageously also comprises at least one fatty phase structuring or gelling agent, especially chosen from waxes, polymeric thickeners or gelling agents, organogelling agents and mixtures thereof.

3) organogelling agents.

Galenic form

The composition according to the invention advantageously contains less than 2% by weight of water and preferably less than 1 % by weight of water relative to the total weight of the composition, or is anhydrous. The term "anhydrous" especially means that water is preferably not deliberately added to the composition, but may be present in trace amount in the various compounds used in the composition. The composition is advantageously in the form of a solid, a paste or a cream.

Preparation process The composition according to the invention may be produced by known processes, generally used in the cosmetics or dermatological field.

A composition according to the invention may be prepared advantageously by using, for at least one step of the process, a mixing device such as a roll mill comprising two rolls revolving in opposite directions, between which the paste passes, or a screw- mixer extruder. A screw-mixer extruder is preferably used.

The rest of the liposoluble ingredients may then be mixed together at a temperature of about 100°C. The ground material or the predispersed active agents may then be added to the oily phase.

The composition is obtained preferably by a high-temperature mixing process or by an extrusion process.

In order to effectively incorporate the waxes and the fillers, it is advantageous to carry out the preparation of the composition or at least one step of this preparation, in particular the preparation of the oily phase or one step of the preparation of the oily phase, in a screw-mixer extruder, subjected to a temperature gradient ranging from 100°C to 20°C. In particular, it is advantageous to carry out the mixing of the fillers, waxes and at least one oil, in a screw-mixer extruder, subjected to a temperature gradient ranging from 100°C to 20°C. Such a preparation is especially described in patent applications EP 1 005 856, EP 1 005 857 and EP 1 013 267.

Application process

The application process consists in spreading the composition described previously over the recessed areas, in particular of the skin, using the fingers or preferably with a suitable applicator.

Thus, the composition may be applied with precision using a tool, especially a spatula. Alternatively, the composition may be applied with less precision, and slightly overflow beyond the edges of the recessed area to be treated. In the latter case, the composition that is found at the sides will be able to be levelled off, for example with a tool that will act as a scraper. It is also possible to remove the product via absorption, suction, evaporation, or rinsing, for example with a special composition.

The applicator will ideally be chosen to both remove and spread the product.

The applicator could be separate from the cosmetic composition or in the same packaging. Any applicator capable of removing the composition could be used, for example one having a tip made of silicone, of foam or of flocked fabric. The applicator may comprise a flat tip, of cylinder of revolution or cone shape.

Preferably, the applicator will have a flat silicone tip, of silicone spatula type.

The applicator will have a tip with a size suitable for the area to be treated.

The applicator could comprise a vibrating member or a heating member to facilitate the application of the composition.

Application to the face may be carried out before or after the application of other facial products, such as for example a foundation.

The invention is illustrated in greater detail in the examples that follow, which are given as non-limiting illustrations. The percentages are weight percentages.

The powder phase B is mixed using a Baker Perkins mixer.

Phase A is heated at 100°C and stirred until a uniform mixture is obtained.

The two phases are introduced at the inlet of an extruder heated to 90°C then cooled to

10°C in the last barrel of the extruder. The composition according to the invention contains 8% of adhesive resin, 38.3% of liquid fatty phase and 37.5% of pulverulent phase. The comparative composition does not contain adhesive resin.

The composition according to the invention was characterized by the following rheological parameters: - the destructuring yield stress or flow point τ ₀ was determined by performing a stress sweep, using a Haake CS150 controlled stress rheometer at a temperature of 25°C;

- the elastic modulus was measured for a stress frequency of 1 Hz, in the "linear viscoelasticity" zone defined by the fact that the stress applied during the measurement is lower than the destructuring yield stress of the composition.

Its elastic modulus is 100 000 Pa and its yield stress is 600 Pa.

The composition was applied, using an LPE-05 silicone spatula sold by the company TOKIWA Corporation, to the imperfections of relief before application of a liquid foundation to the whole of the face.

The two compositions are applied easily to the face and make it possible to effectively mask the skin imperfections, ie recessed area, such as pores or acne scars, even deep ones. The composition according to the invention has a very good hold over time on the skin, whereas the comparative composition readily detaches from the face or has highlight points after several hours.
