Description

USE OF AN ORAL COMPOSITION COMPRISING A MIXTURE OF AT LEAST ONE POLYPHENOL, ZINC, AND VITAMIN C.

The present invention relates to uses and methods, in particular cosmetic or pharmaceutical, using an oral composition comprising a mixture of at least one polyphenol, zinc, and vitamin C.

In general, it is desirable to improve the appearance of the skin, beautify the skin, treat imperfections or skin disorders. Such objectives may be pursued in particular to reduce or even avoid certain undesirable effects on the skin caused by (i) various cosmetic or pharmaceutical physical or chemical treatments, or (ii) skin aggressions due to environmental causes.

For purposes of this disclosure, cosmetic treatments include aesthetic treatments.

For the purposes of the invention, topical treatments include topical physical and chemical treatments.

Chemical treatments include oral administration and topical application to the skin or scalp of at least one cosmetic or medical substance.

The physical treatments include treatments comprising a step of exposing the skin or scalp (i) to a mechanical action, for example a step of abrasion of the skin or scalp to cause desquamation or (ii) ) to a source of energy, for example light energy such as UV radiation, infra-red radiation, laser light, pulsed light source, etc. In particular, physical treatments include aesthetic treatments selected from photodynamic therapy using lasers, blue or red lights, intense pulsed light (IPL) or non-intense "gentle waves" type. Physical treatments also include those specifically targeting the sebaceous glands, as described in "Cosmetic Applications of Laser and Ligh Based Systems" (William Andrews Press, Gupreet S. Ahluwalia ed., Chapter 21: Photodynamic Therapy for Acne, rejuvenation and Hair removal. pp399-411; 2009, which includes resurfacing treatments using a laser.

For purposes of this disclosure, the term "treatment" includes the implementation of a method of treatment on a subject. Said method of treatment includes at least one step of administering at least one asset, where appropriate in the form of a composition comprising said asset (s), which (s) is (are) optionally combined with an excipient or a combination of physiologically acceptable excipients.

A "cosmetic treatment" encompasses the implementation of a method of cosmetic treatment on a subject, and comprises at least one step of administering at least one cosmetic active agent, optionally combined with one or more cosmetically acceptable excipients.

"Pharmaceutical treatment" includes the implementation of a method of pharmaceutical treatment on a subject, and comprises at least one step of administering at least one pharmaceutical active ingredient, optionally combined with one or more pharmaceutically acceptable excipients. Pharmaceutical treatments include dermatological treatments. The term "pharmaceutical / dermatological" means "pharmaceutical, especially dermatological".

Skin reactions, including skin irritation, are known to be induced by a variety of exogenous causes, including (i) chemical causes, eg, xenobiotics, antigens, allergens, chemicals, compounds that may cause skin irritation, cosmetic chemical peeling processes, (ii) environmental origin (temperature, climate, UV radiation, atmospheric pollution, especially heavy metals, ozone, cigarette smoke ...) or (iii) of physical origin, including of mechanical origin (friction, shaving).

In particular it is known that skin irritations or cutaneous reactions of discomfort can be induced by certain treatments, which respectively include certain cosmetic treatments and certain pharmaceutical treatments, including certain dermatological treatments, administered topically or orally.

Skin reactions may also manifest as discomfort experienced by the user on the skin. It can typically be redness, itching, heating, burning, tingling, tugging. Cosmetic treatments can remedy this discomfort.

Skin reactions can also be caused by oral pharmaceutical treatments. For example, cutaneous reactions are known, in particular skin discomfort, skin dryness or skin peeling, which may be caused by the oral administration of retinoid compounds.

Skin discomfort can be caused by some topical treatments to limit skin imperfections or disorders, including imperfections or skin disorders associated with acne, associated with oily skin or associated with aging skin.

Acne occurs most often in the youngest teens from the age of 11-12 with a peak of activity around 15-18 years indicating in particular the contribution of sex hormones in its etiology. It can then be expressed throughout life in varying degrees and most often in outbreaks. In parallel with the extent of the affected areas, various stages of the pathology, are described such as follicular hyper proliferation, sebum production, even inflammation as well as activity levels of Propionibacterium acnes. Acne can be classified by the dermatologist since the moderate stages to very severe stages in relation to the types of cutaneous lesions observed such as comedones, papules, pustules nodules or even scars generated. The major treatments for acne or its unsightly aesthetic consequences are topical or systemic retinoids, antibiotics, topical benzoyl peroxide alone or in combination with topical or systemic antibiotic treatments or even in the most extreme cases of treatment with chemical peels or even laser treatments or photodynamic therapy using especially photoactivatable derivatives such as 5-aminolevulinic acid as described in acne vulgaris: lasers, light sources and photodynamic therapy, an update 2007; Michael H Gold, Rev.Anti expert infected. Ther. 5 (6), 1059-1069 (2007).

Oily or hyperseborrhoeic skin is characterized by a shiny skin, sometimes oily in appearance, thick, with enlarged pilosebaceous pores. Sebaceous hypersecretion is most often linked to hyperandrogenism due either to an androgen hyperproduction by an endocrine gland, or to a peripheral hyperproduction notably in the sebaceous gland. This sebaceous hypersecretion, combined with an accumulation of epithelial cells resulting from an abnormal cell multiplication, can lead to an obstruction of the sebaceous follicles, localized especially on the face, which can evolve into comedones. In addition, an anaerobic resident bacterium, Propioni bacterium acnes, proliferates in this environment rich in sebum and follicular cells and may contribute locally to inflammation.

A fatty skin with an acne tendency therefore generally has cutaneous imperfections, dilated pores, an inhomogeneous texture of the skin, redness and a shiny and shiny appearance.

The cosmetic treatment of this type of skin generally involves the topical application to the skin of a mixture of compounds making it possible to act on the various causes of the imperfections and in particular to control the production of sebum (retinoids, zinc salts, cinnamon, ulmary or laminar extracts) and / or to promote desquamation (alpha- and beta-hydroxy acids) and / or to limit microbial growth (iodopropynyl butylcarbamate, triclosan, octoxyglycerine, octanoylglycine).

Mixtures comprising zinc and copper pidolates, in a composition also comprising at least one α-hydroxy acid, at least one algae extract and at least one haloalkynyl carbamate, are also known from patent application EP 1 437 124, for the cosmetic treatment of acne-prone skin. In addition to the expected beneficial effect in terms of curative effect, however, the active ingredients can cause cutaneous intolerance of the skin reaction type of discomfort on the skin.

Also, use is made of cosmetic compositions containing, for example, keratolytic and / or desquamating active ingredients for combating aging, and in particular exfoliating active agents and / or promoting agents for cell renewal, such as α-hydroxy acids (in particular lactic acid, glycolic acid). , citric), β-hydroxyacids

(especially salicylic acid) or retinoids (especially retinoic acids, all trans or 13-cis-retinol-adapalene ...).

In particular circumstances, the use of these active ingredients, for example in high concentrations, may also lead to the appearance of skin irritations or skin reactions of discomfort.

In order to temper the undesirable effects they generate, compounds that can cause skin irritation or skin discomfort can be used in low doses. Alternatively, the treatment must be stopped prematurely. In both cases, it leads to a reduction, sometimes substantial, of the effectiveness of said treatments. In general, there is a need for compositions or methods for reducing or avoiding skin imperfections, skin disorders or discomfort skin.

In particular, there is a need for cosmetic compositions or methods for reducing, partially or totally, alterations or disorders of the skin surface, including skin irregularities, which are caused by physical or chemical treatments. whether in the form of cosmetic treatments or pharmaceutical treatments, or which are caused by affections of the skin, which alterations or irregularities of the skin remain after said disorders are physiologically resolved. By way of illustration, there is a need for cosmetic compositions or methods aimed at reducing, partially or totally, the residual irregularities of the surface of an acneic skin, especially after the treatment of acne has been successfully performed.

There is a need for compositions or methods able to reduce in whole or in part the disadvantages associated with cosmetic or pharmaceutical treatments administered topically or orally, and in particular the cutaneous disadvantages described above, and thus to improve the tolerance of the subjects vis-à-vis these cosmetic or pharmaceutical treatments or increase the effectiveness of such treatments.

In particular, there is a need for cosmetic processes intended to increase the tolerance or effectiveness of cosmetic or pharmaceutical treatments, including dermatological treatments administered topically or orally.

Surprisingly, the inventors have shown that it is possible to reduce certain undesirable effects caused by the implementation of topical cosmetic physical treatments, or by the implementation of cosmetic chemical treatments or chemical pharmaceutical / dermatological treatments, by way of topically or orally, by orally administering a composition comprising at least one combination of polyphenol (s), zinc, and vitamin C. The reduction of undesirable effects caused by these treatments, which is achieved by administering oral composition comprising at least one combination of polyphenol (s), zinc, and vitamin C, allows a better compliance of said treatments by the treated individuals. It is also shown that the reduction of undesirable effects caused by the implementation of the above treatments, through the oral administration of the composition comprising at least one combination of polyphenol (s), zinc, and vitamin C, increases the effectiveness of said treatments.

In particular, it is shown that said undesirable effects are reduced when said oral composition is administered together with said topical physical treatments, said cosmetic applications or said pharmaceutical / dermatological, topical or oral applications.

The inventors have shown in particular that the oral administration of the composition defined above makes it possible to reduce the cutaneous reactions of discomfort caused by cosmetic treatments and certain pharmaceutical treatments, in particular certain dermatological treatments, such as these cosmetic or pharmaceutical treatments. are administered topically or orally.

Disorders and skin imperfections and discomforts include skin reactions such as redness, itching, heat and / or burning sensations, tingling sensation, or tightness.

In particular it is shown according to the invention that the oral administration of a composition as defined above makes it possible to reduce the general discomfort caused by a topical treatment of cutaneous disorders associated with acne.

It has also been shown that the oral administration of a composition as defined above also makes it possible to reduce the general discomfort caused by a treatment of skin imperfections, in particular skin imperfections resulting from hyper-seborrhea. , likely to be accompanied by an obstruction of the pores of the skin.

The present invention relates to the cosmetic use of an oral composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C as a soothing agent.

In advantageous embodiments, said oral composition also comprises magnesium, preferably in the form of a magnesium salt.

In advantageous embodiments, said oral composition also comprises vitamin B6. For the purposes of the present description, a soothing agent exerts, in particular, a reduction effect, partial or total, of skin discomfort caused by the topical application of a physical treatment, for example exposure of the skin to radiation (UV, IR, pulsed light, laser, etc.) or a topical or oral chemical treatment, that is to say a treatment with at least one cosmetic or pharmaceutical active topically or orally. In particular, a soothing agent may partially or completely reduce the redness, itching, heating, burning sensation, tingling sensations and skin tightness sensations that are caused by said cosmetic or pharmaceutical treatment, topical or oral.

In the present description, the composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C can also be designated "soothing agent".

In advantageous embodiments, said oral composition, or soothing agent, also comprises magnesium, preferably in the form of a magnesium salt.

In advantageous embodiments, said oral composition, or soothing agent, also comprises vitamin B6.

The invention also relates to a cosmetic method for increasing the tolerance of a subject to a topical or oral cosmetic or dermatological treatment comprising the oral administration of a composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C.

In advantageous embodiments, said oral composition also comprises vitamin B6.

Thus, the present invention relates to a cosmetic or pharmaceutical process, or a composition for the implementation of such a method, which process increases the tolerance of a subject to a topical or oral cosmetic or dermatological treatment when said process or said composition is able to reduce, partially or totally, the undesirable cutaneous effects caused by said cosmetic or pharmaceutical treatment. When a cosmetic process or a cosmetic composition are concerned, said adverse effects especially include skin discomfort, as defined above. The increase of the tolerance of an individual to a cosmetic or pharmaceutical treatment, oral or topical, can be illustrated by a better observance of the patient vis-à-vis said cosmetic or topical pharmaceutical treatment.

According to still other aspects, the invention relates to a cosmetic process for the prevention or treatment of cutaneous reactions caused by a topical or oral cosmetic treatment, comprising the topical or oral administration of at least one cosmetic active agent , and the oral administration of at least one comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin vs.

It is also shown according to the invention that the implementation of the method defined above makes it possible to increase the effectiveness of a topical treatment against imperfections or skin disorders. In particular, it is shown in the examples that the administration of said oral composition increases the effectiveness of a topical treatment, in that the beneficial effects of said topical treatment are maintained over time because of the oral composition, after stopping. said topical treatment.

Unexpectedly, the inventors have shown that the systemic administration of a composition comprising at least at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a salt zinc, and (iii) vitamin C, is able to reduce the undesirable effects, in particular the effects of discomfort, caused by a local treatment, and more specifically by cosmetic treatments and certain pharmaceutical treatments, in particular certain treatments. whether these cosmetic or pharmaceutical treatments are administered topically or orally. Said systemic administration of said soothing agent is also able to reduce the undesirable effects caused by another oral, cosmetic or pharmaceutical systemic treatment.

Also, thanks to the process using the oral composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C, the duration of the cosmetic or pharmaceutical treatment, topical or oral, against disorders and / or skin discomfort can be reduced, compared to the time required when said cosmetic treatment or pharmaceutical is not accompanied by the oral administration of said soothing agent.

The inventors have also shown that it is advantageous to continue the oral administration of the composition comprising at least at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C, after stopping the cosmetic or pharmaceutical treatment. It is shown in particular that, during this additional period of time, said oral cosmetic composition may be used in substitution of the cosmetic (s) or pharmaceutical (s), topical (s) or oral (s) active (s).

The results obtained by the inventors show that the composition for oral administration above can be used successfully to reduce, partially or totally, the residual skin changes resulting from a cosmetic or pharmaceutical treatment, when said composition for oral administration is administered after said cosmetic or pharmaceutical treatment. In other words, said composition for oral administration can be used successfully, in particular after the resolution of a physiological problem of the skin, for example after treatment of the acute and / or eruptive phase of acne.

In other aspects, it may be advantageous to precede the beginning of the topical or oral cosmetic or pharmaceutical treatment with a preliminary period of administration of the oral composition comprising at least at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C.

It is therefore shown according to the invention that the oral administration of a composition comprising at least at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a salt zinc, and (iii) vitamin C, is capable of increasing the effectiveness of a cosmetic or pharmaceutical treatment, which encompasses a topical cosmetic or pharmaceutical treatment and a cosmetic or pharmaceutical treatment / dermato oral logic.

It is thus shown in the examples that the administration of said oral composition increases the effectiveness of a topical treatment, in that the beneficial effects of said topical treatment are maintained over time because of the oral composition, after the stop said topical treatment. The present invention also relates to a cosmetic method for increasing the effectiveness of a topical or oral cosmetic treatment against cutaneous imperfections, in particular against cutaneous imperfections of oily or hyperseborrhoeic fatty skin, comprising oral administration. an oral composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C.

In advantageous embodiments, said oral composition also comprises vitamin B6.

According to other aspects, the present invention relates to the cosmetic use of an oral composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a salt zinc, and (iii) vitamin C, for the prevention or treatment of aesthetic defects of the skin.

For the purposes of the invention, the skin imperfections include gloss, heterogeneity and irregularity of the color and / or relief, thickening, opacity, skin texture, shiny appearance, appearance greasy, sticky or messy, pimples and scars that may result, unsightly closed comedones or open, microcysts, nodules, papules and pustules. Aesthetic defects also include residual irregularities of the surface of the skin caused by cosmetic or pharmaceutical treatments, or caused by physiological conditions, for example by a hyperseborrhoeic state or an acne state, which justified the application of said cosmetic treatments or pharmaceuticals. For example, aesthetic defects include residual signs of an acne skin condition. In particular, aesthetic defects include residual skin surface irregularities caused by microcysts, nodules, papules and pustules.

Skin imperfections, especially of oily, acne-prone or hyperseborrheic skin, include defects in the sharpness of the skin, the gloss of oily skin, a cloudy or heterogeneous complexion, the shiny appearance, the greasy, sticky or messy appearance and that the difficult holding of makeups and powders related to this hyper seborrhea, and in particular the aesthetic defects and skin imperfections detailed below. More particularly in the field of skin color, it can be seen that heterogeneity of the complexion showing areas of different colors even plates or spots, buttons, scars and closed or open comedones including black dots; there is also an irregularity of the surface condition in connection with dilated pores, pimples, scars or microcysts or even fine lines compared to the largest acne lesions. The condition of the skin is particularly degraded with thickened skin, opaque in places showing sometimes dull areas sometimes bright and shiny areas or even dander, thus highlighting great disparities in the grain of the skin, especially for the face at a T-shaped area (referred to as the T-zone) encompassing the forehead, nose and chin as opposed to the rest of the face just as these disparities may also appear on the chest and upper back with respect to areas often less affected like arms and legs. Sometimes, these aesthetic defects can even affect the hair including hyperseborrhoeic individuals by loading by contact with sebum produced in the face and thus include weighing, dulling, sticking and affect the color.

According to other aspects, the present invention also relates to an oral composition comprising at least one comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt and (iii) vitamin C for the prevention or treatment of cutaneous reactions to cosmetic or dermatological, oral or topical treatment.

As is apparent from the following, the oral administration of the soothing agent according to the invention can be carried out previously, jointly and / or after the topical or oral application of the cosmetic or dermatological treatment which is sought after. to get rid of undesirable skin reactions that it is likely to induce.

In certain embodiments of the cosmetic use or process of the invention, said topical or oral cosmetic or pharmaceutical application and said oral administration are carried out in less than a part in conjunction with one another.

In certain embodiments of the cosmetic use or process of the invention, said application of a cosmetic or pharmaceutical composition, topically or orally, and said oral administration of the soothing agent are carried out simultaneously, intermittently, or separately in time.

Within the meaning of the invention, said cosmetic or pharmaceutical treatment, topical or oral, and said oral administration of the soothing agent are carried out simultaneously when the implementation of the method comprises at least one period of time during which the cosmetic or pharmaceutical treatment (eg the topical (s) or oral active (s)) and the oral composition of soothing agent are applied / administered simultaneously, ie during the same 24-hour period, for example during the same day, if necessary at different times of the same 24-hour period, the if necessary of the same day. Said period of time during which the cosmetic or pharmaceutical treatment (e.g., the topical active (s)) and the oral composition of soothing agent are applied / administered simultaneously may be of varying duration. It is at least a day.

Said application of a cosmetic or pharmaceutical composition, topically or orally, and said oral administration of the soothing agent are carried out intermittently when the cosmetic or pharmaceutical treatment (eg the active agent (s) topical (s)) and the oral composition of soothing agent are administered alternately over time, that is to say at intervals of more than 24 hours. When the cosmetic or pharmaceutical application and the oral administration of the soothing agent are carried out intermittently, (i) the period of administration of the cosmetic or pharmaceutical composition, between the beginning and the cessation of said cosmetic or pharmaceutical treatment and (ii) the period of oral administration of the soothing agent, between the onset and cessation of said oral treatment, overlap.

Said topical application and said oral administration are carried out separately in time when said cosmetic or pharmaceutical composition and said soothing agent oral composition are administered for periods of time which never overlap.

However, according to preferred embodiments, the cosmetic process of the invention is characterized in that it comprises:

the oral administration, for a first period of time, of said composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and iii) vitamin C.

the administration, for a first period of time, of a topical or oral cosmetic or pharmaceutical treatment (for example, the topical active agent (s)); and it being understood that at least a portion of said first period of time and at least a portion of said second period of time are simultaneous. The fact that at least some of said first period of time and at least a portion of said second period of time are simultaneous defines a period of joint administration of the two compositions.

The administration of the cosmetic or pharmaceutical composition, or the oral administration of the soothing agent is carried out at least once per period of time. Preferably, the periods of time can be divided into units of time, in particular of equal duration, for example in day or week. In such an embodiment, oral administration or topical administration is performed at least once per unit of time, for example at least once a day.

Thus, according to one embodiment, the method of the invention comprises (i) a first period of time comprising the simultaneous or intermittent administration of the oral composition of soothing agent and of the cosmetic active agent (s) ( s) or pharmaceutical (s), topical (s) or oral (s), said first period of time being followed by (ii) a second period of time comprising oral administration of said active ingredient (s) cosmetic (s), in the absence of the oral composition of soothing agent.

According to another embodiment, the method of the invention comprises (i) a first period of time comprising the administration of the oral composition of soothing agent in the absence of the cosmetic active (s) or pharmaceutical (s), topical (s) or oral (ux), said first period of time being followed (ii) a second period of time comprising the joint administration of the cosmetic (s) or pharmaceutical (s) active (s) (s) and the oral composition of soothing agent.

In some embodiments of the method, said oral cosmetic composition of soothing agent is administered during only a part or during the entire duration of administration of said (s) cosmetic or pharmaceutical active (s), topically or orally.

In preferred embodiments of the method, the administration of said oral soothing agent is continued after stopping the administration of said (said) cosmetic or pharmaceutical active ingredient (s).

Advantageously, the cosmetic or pharmaceutical active agent (s) is (are) administered topically or orally, continuously, that is to say daily, or intermittently, for a period ranging from 5 days to 120 days, which ranges from 10 days to 60 days, and from 20 days to 45 days, for example 60 days. Advantageously, said soothing agent is administered orally, continuously, that is to say daily, or intermittently, for a period ranging from 5 days to 200 days, which encompasses from 10 days to 150 days, and from 20 days to 100 days, for example 90 days.

In preferred embodiments of the cosmetic process of the invention, the administration of said soothing agent orally is initiated simultaneously with the application of the cosmetic or pharmaceutical composition and is extended beyond the latter. For example, (i) administration of the cosmetic (s) or pharmaceutical (s) active (s) and (ii) administration of the oral soothing agent are initiated simultaneously, and carried out jointly, so simultaneous or intermittent, for a first period of at least 5 days and preferably at least 30 days, then oral administration of said composition is continued for a second period subsequent to said first period, said second period having a duration at least 5 days and preferably at least 10 days,

As already mentioned, the invention also relates to an oral composition comprising at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C, for the prevention or treatment of cutaneous reactions to a cosmetic or dermatological treatment, topical or oral.

The invention also relates to the use of at least at least (i) a polyphenol or a mixture of polyphenols, (ii) zinc, preferably in the form of a zinc salt, and (iii) vitamin C for the preparation of a pharmaceutical composition, for the prevention or treatment of cutaneous reactions caused by an oral or topical cosmetic treatment, or by an oral or topical pharmaceutical / dermatologic treatment, in particular a topical dermatological treatment.

Topical pharmaceutical or dermatological treatments include the treatment of hyperseborrhoeic skin, skin imperfections, signs of skin aging, skin pigment disorders, acne, as well as moderate to severe dandruff conditions.

The various aspects of the present invention are also defined below in connection with the description of (i) the soothing oral administration agent composition used and (ii) cosmetic or pharmaceutical / dermatological treatments, by or topical or oral whose adverse effects are reduced, or whose effectiveness is increased, when said oral composition of soothing agent defined in the present description is administered.

In advantageous embodiments, said oral composition also comprises vitamin B6.

Composition for oral administration (soothing agent)

The compounds contained in the composition for oral administration, also called soothing agent in the present description, are advantageously used in doses or quantities for which an optimal effect is expected.

Thus, in certain embodiments, the method is characterized in that said oral composition is suitable for the daily administration of a combination of compounds comprising (i) from 0.1 to 5000 mg of a polyphenol or a mixture of polyphenols, (ii) from 0.1 to 1000 mg of zinc, preferably in the form of a zinc salt, and (iii) from 1 to 3000 mg of vitamin C.

polyphenols

In particular embodiments, said oral cosmetic composition is suitable for the daily administration of 10 to 500 mg, advantageously 30 to 200 mg, of a polyphenol or a mixture of polyphenols.

The polyphenol compounds include a large family of compounds widely distributed in the plant kingdom. They are found in particular in plants, from roots to fruits. Among the classes of polyphenols, there may be mentioned flavonoids, proantocyanidines, lignans, lignins, stilbenes, phenolic acids, coumarins. Thus, the polyphenol compound used in the context of the present invention may be in an isolated form or in all the forms mentioned below.

According to the invention, the term "polyphenols" is more particularly understood to mean compounds of the flavonoid type, that is flavones, flavonols, isoflavones, anthocyanins, flavanols, proanthocyanidines, flavanones, chalcones (eg phloridzin), stilbenes and the chlorogenic acid family.

In the context of the present invention, the polyphenol compound may in particular derive from plant extracts chosen from extracts of green tea, grapes such as Vitis Vinifera, pine and in particular pine bark, apple, blueberry, hops, guava, cocoa, wood such as chestnut, oak, horse chestnut, hazelnut.

The term "polyphenol compound" in the context of the present invention therefore also extends to the plant extract itself, rich in these polyphenol compounds. The avononoids are the main group of polyphenols.

The catechol polyphenols constitute, for their part, a subgroup of the avonoid, which also include the flavanones, the flavones and anthocyanins, and the avonols.

Particularly suitable are the avonols, anthocyanins, flavanols, proanthocyanidines and flavanones and stilbenes.

Flavanols are especially chosen from catechins and gallocatechins.

Procyanidins are polymers of avonols present as low-level polymer blends. They can be associated with catechins in plant extracts.

The polyphenols or polyphenol mixtures include catechin, epicatechin, repigallocatechin-3-O-gallate, epigallocatechin, epicatechin-3-gallate, procyanidins, proanthocyanidins, and mixtures thereof.

It is particularly advantageous to use catechin monomers optionally mixed with procyanidin oligomers (OPC).

These inputs of polyphenols can be made from isolated compounds and / or from plant extracts and mixtures thereof.

It will be possible according to the invention to use plant extracts that can provide all of these polyphenols.

More particularly, catechins are very abundant in tea (Camellia

Simensis), coffee and grapes (Vitis Vinifera) and other fruits (apple, pear, pine cone) (Pinus Maritima). The beverages (wine, beer, tea) and chocolate (Theobroma Cacao) are sources that can constitute inputs of catechins according to the invention.

These polyphenols may be used alone or used in the form of mixtures of several polyphenols.

By way of example, mention may be made of an extract of grape seed at 83% OPC, a red wine extract with 30% total polyphenols and / or a green tea extract with 30% catechins.

Procyanidin oligomers (OPC) can be provided by a grape seed extract, which is titrated according to its OPC titre. By way of example, for an 83% OPC grape seed extract, above, it can be used at a dose of about 200 mg / day, ie about 170 mg / day OPC.

The polyphenols can be selected from one of the above categories, and mixtures can also be made. The composition for oral administration may comprise from 0.01 to 30% by weight of at least one polyphenol, relative to the total weight of said composition. In preferred embodiments, said composition for oral administration comprises from 0.1% to 60% by weight, for example from 5% to 40% by weight, based on the total weight of said composition.

It is specified that the polyphenols of the chlorogenic acid family are found mainly in coffee extracts, in extracts of artichoke, or in extracts of chicory. The family of chlorogenic acids includes compounds formed by a chlorogenic acid, or a plurality of chlorogenic acids, conjugated with quinic acid. The chlorogenic acids include chlorogenic acid per se (iran-5-O-caffeylquinic acid) as well as ferulylquinic acid, p-coumarylquinic acid, sinapylquinic acid, dicafeylquinic acid, caffeyl-2,6-dicarboxylic acid, diferulylquinic acid, di-p-coumarylquinic acid and dimethoxy cinnamylquinquinic acid.

Most preferably, a mixture of polyphenols in the form of a grape seed extract is used. Zinc

In particular embodiments, said oral cosmetic composition adapted to the daily administration of 1 to 100 mg of zinc, advantageously from 5 to 30 mg of zinc, preferably in the form of a salt or a zinc oxide, and most preferably zinc gluconate.

In the present description, an amount of salt or zinc oxide refers to the amount of elemental zinc contained in said salt or said oxide. As an illustration, 24.5 mg of zinc gluconate is expressed as 3.52 mg of zinc in the form of gluconate.

Zinc is preferentially in the form of a salt or an oxide.

The zinc salts are chosen in particular from acid salts and halides.

The acid salts include sulphate, borate, and carboxylic acid salts. The carboxylic acid salts include acetate, carbonate salts.

Halides of chloride, iodide and fluoride.

Preferentially, the zinc salts are chosen from gluconate, acetate, sulphate, chloride, citrate, lactate or carbonate. In some embodiments, the composition for oral administration comprises from 0.001% to 10% by weight, and preferably from 0.01% to 5% by weight of zinc, where appropriate in the form of a salt or a zinc oxide, based on the total weight of said composition.

In the present description, an amount of salt or magnesium oxide refers to the amount of elemental magnesium contained in said salt or said oxide. By way of illustration, a quantity of 266.67 mg of magnesium sulfate is expressed as 53.8 mg of magnesium in the form of sulfate.

Magnesium salts include sulfate, chloride and phosphate.

Most preferably, the magnesium salt is magnesium sulfate.

In some embodiments, the composition for oral administration comprises from 0.1% to 70% by weight, and preferably from 1% to 40% by weight of magnesium, where appropriate in the form of a salt, by weight. relative to the total weight of the composition.

EXAMPLE 8 Clinical Results Obtained with the Cosmetic Procedure in the Case of a Topical Treatment with Benzoyl Peroxide (BPO) in Acneic Substances

This dermatologically controlled study was conducted in women (n = 166) aged 18 to 40 years with mild to moderate acne. In a first phase, these women were divided into two treatment groups:

- group 1 treated with benzoyl peroxide 5% (w / w) for 60 days at one application per day (control group)

- Group 2 treated with benzoyl peroxide 5% (w / w) for 60 days at a rate of one application per day associated with the daily intake of the oral supplement as described in Example 1. The control of the tolerance to the treatments was carried out after 30 and 60 days by means of questionnaires given to the dermatologists and the subjects participating in the study.

The results of the overall clinical assessment performed by dermatologists after 60 days are shown in Table 8 below. The figures in Table 8 correspond to% of agreement response more completely agree.

Table 8

* (S): Statistically significant The results of the global clinical assessment performed by users after 60 days are shown in Table 9 below. The figures in Table 3 correspond to the% of agreement response more completely agree.

* (S): Statistically significant

The results of Tables 8 and 9 show, after 60 days of treatment, the superiority of BPO treatment + oral composition versus BPO alone in terms of eliminating / reducing acne lesions, obtaining a healthier and sharper skin. , attenuation of the shiny appearance of the oily skin, purifying and matifying action, unification of the complexion.

In addition, the efficacy results show that, after two months of treatment, the combination of the oral supplement as described in Example 1 and 5% benzoyl peroxide makes it possible to increase the rate of subjects statistically significantly. presenting a "Net improvement" of acne lesions compared to benzoyl peroxide 5% alone.

Group 1: out of 53 subjects, 21 subjects show a net improvement (40%) Group 2: out of 113 subjects, 71 subjects show a net improvement (63%)

Tables 10 (evaluations by dermatologists) and 11 (self-evaluations of subjects) summarize the tolerance results obtained in groups 1 and 2. Quite unexpectedly, a statistically significant difference was found as early as 30 treatment days in favor of group 2. In other words, the tolerance to treatment in group 2 is better than that of group 1 highlighting the interest of the oral composition as described in example 1 to improve tolerance to benzoyl peroxide.

The results of the dermatologic evaluation of treatment tolerance in groups 1 and 2 after 60 days of treatment are shown in Table 10 below. The results are expressed in% of subjects.

The food composition therefore advantageously replaces the topical treatment after a 60-day etching phase combining the oral composition and the topical medicinal treatment, in other words, the oral composition alone justifies an efficacy superior to that of BPO on items such as reducing / eliminating acne lesions, obtaining a clearer and healthier skin, reducing the shiny appearance of oily skin, homogeneity of complexion, purifying and mattifying action. This superiority is also accompanied by a better tolerance in group 3 compared to group 1.

The food composition therefore advantageously replaces the topical medicinal treatment after a 60-day etching phase combining the oral composition and the topical medicinal treatment.
