     TECHNICAL FIELD 
     The subject matter of the present invention is a new use of an extract of plant origin of  Globularia  and a preferred method of obtaining said extract by in vitro plant culture. 
     The present invention concerns more generally the cosmetics industry, that produce and/or use extracts of plant origin for preventing of treating disorders of skin, scalp, mucous and appendages (such as hair, eyelashes, eyebrows, nails or hairs) of animal or human mammals. 
     According to the invention, “extract of plant origin” means an extract that can be obtained directly from a plant or that can be obtained by culture of plant cells or tissues. 
     BACKGROUND ART 
     In cosmetics, there are many ways to improve the overall condition of the skin, hair and nails including imparting or restoring skin tone, hydration, pigmentation or depigmentation, protection against external aggressions such as UV radiations or coldness, calming irritation, redness, acne, reducing micro-oedemas (such as bags under the eyes), reducing dark circles, signs of aging such as wrinkles, fine lines, pigmentation, restoring suppleness and elasticity, treating hair loss, acting on the adipose tissues, adding volume, density, improving the texture etc. 
     Since a long time and in all parts of the world, the plant kingdom is an abundant and widely used source of biologically active substances in particular in the pharmaceutical and cosmetics fields.  Globularia  genus belongs to the Plantaginaceae family, Globularioideae subfamily, and comprises several species, including those known:  Globularia alypum, Globularia bisnagarica, Globularia cordifolia, Globularia nudicaulis, Globularia vulgaris, Globularia gracilis, Globularia repens  and  Globularia valentina.    
     They are small herbaceous plants, with leaves simple, alternate, with flowers in round heads, from subtropical to temperate regions. They are found mainly in Europe and North Africa. 
     EP0006059 discloses a process for extracting  Globularia  alypum and  Globularia  vulgaris according to which the whole plant, stems, or the leaves are treated by means of two extraction solvents differing in polarity. The extract obtained according to this process is useful in human and veterinary therapy, in particular in the treatment of brucellosis. 
     Specific flavones, flavonoids, iridoids and phenolic compounds have been identified in the  Globularia  genus, and in particular in the  Globularia cordifolia  species (“6-Hydroxyluteolin and Scutellarein as phyletic markers in higher plants”, in the journal Phytochemistry, vol. 10, no. 2, 1971-02, p367-378; “Globularifolin, a new acyl iridoid glucoside from  Globularia cordifolia ”, Helvetica Chimica Acta, vol. 63, no. 1, 1980-01-23, p. 117-120; “Phenolic compounds from  Globularia cordifolia ”, Turk J Chem, vol. 28, 2004, p. 455-460 and “Iridoid and bisiridoid glycosides from  Globularia cordifolia” Journal of biosciences, vol.  58c., 2003, p. 337-341). 
     SUMMARY OF THE INVENTION 
     The aim of the present invention is to provide a new extract of plant origin for the cosmetic industry always in demand of new active ingredients. 
     To this aim, the present invention proposes the use of an extract of plant origin of the  Globularia  genus for a non-therapeutic cosmetic treatment of the skin and/or appendages. 
     The skin is subject to many external stresses: UV, electromagnetic waves, oxidants, pollutants, biological agents, etc. These stresses induce, among other deleterious effects, micro-inflammatory phenomena that are more or less chronic and the formation of toxic products in epidermal cells or at their periphery. 
     Among these products are the pre-inflammatory mediators and some growth factors that cause a local over-densification of epidermal nerve endings associated with a hyper-reactivity to external stimuli. This results in lowering the threshold of the skin regarding these stimuli. It becomes very sensitive, generating discomfort but also most of the time transient rednesses. 
     In addition, the skin gradually accumulates debris of various origins, composed of proteins, carbohydrates and altered lipids. These components (carbonylated proteins, lipoperoxides, lipofuscin, etc.) will also act as toxins that disrupt the physiology and cellular homeostasis and modify fragile metabolic balances. 
     Over time, they alter mitochondrial respiration, membrane integrity, enzymatic activity, and detoxification mechanisms such as the proteasome. Such changes can cause changes in behavior of certain cells such as stem cells. As a matter of fact, the latter are in a particular environment in which the change may lead to the weakening of their character and their progenitor phenotype (cell size larger, reduction of the multipliers capacity etc), making them less able to hold their role in the renewal of keratinocytes. 
     Experimental data show that mild stress received in an early stage can delay degradation and therefore skin aging, helping the body to later deal with more severe stress (external events). This phenomenon is called hormesis. It is based on the activation of detoxification mechanisms and cellular defense in response to a mild stress or in response to substances which are said to have a hormetic effect (molecules called hormetins). The hormesis will contribute to a better adaptation of the cell and thus of the body with regards to subsequent stresses, allowing it to fight more effectively against the harmful effects mentioned above. 
     It is thus very interesting from a cosmetic point of view to mimic the effects of hormesis to improve the physiology of the skin and allow it to better fight against future stresses and thus against skin ageing. 
     For a better understanding of this hormetic effect, it can be spoken of an anti-ageing vaccine. However, the hormetic effect, although showing its effect on long term (anti-aging), will also improve rapidly the condition of the skin on the short term by giving it a lower sensitivity to external stresses and by providing more transparency and brightness (or radiance) to the skin. 
     It is this set of original and unexpected properties that has been particularly shown for the extract of  Globularia  through a series of tests (developed below). 
     Thus, the detailed description given below, shows that this extract has in vivo properties completely unexpected and original in targeted technical fields, comprising increasing skin transparency and cutaneous reactivity, producing a remarkable effect on the visual quality of the skin: radiance, clarity, purity and homogeneity of color, smoothness, etc. thanks in particular to a stimulation of the hormetic defenses of the skin. 
     Furthermore, the  Globularia  extract of the invention has shown efficacy on dermal stem cells. Dermal stem cells are involved in healing, morphogenesis and development of the hair follicle. Other properties are linked to dermal stem cells: they are precursors of the dermis, maintain and form a reservoir of cells thanks to their potential to differentiate into several cell types. 
     An increased and maintained number of dermal stem cells mean more fibroblasts in good shape in the dermis and thus more macromolecules and fibers (collagen, elastin, etc.). All cosmetic applications related to the replumping of dermis can be envisaged, for example the treatment of wrinkles and fines lines, or treatment of firmness. Another application is hair regrowth that can be enhanced and/or hair loss prevented since it is known that the formation of a complete hair follicle is induced by dermal cells. 
     Detailed in vitro example studies are given thereafter showing that the invention can apply in particular for:
         preventing and/or treating skin ageing by stimulating the detoxification reactions and cellular regeneration through a hormetic type response; and/or   improving the radiance and/or transparency of the complexion; and/or   for preventing and/or treating sensitive and/or reactive skins; and/or   for preventing and/or treating rednesses; and/or   for preventing protein glycation; and/or   for increasing and/or maintaining the number of dermal stem cells; and/or   for increasing and/or maintaining the dermal macromolecules, in particular collagen and elastin; and/or   for increasing the volume of the dermis (replumping of the dermis); and/or   for preventing and/or treating fines lines and wrinkles; and/or   for firming skin; and/or   for preventing hair loss and/or stimulating hair regrowth.       

     Other uses are possible, whitening, moisturizing, slimming, epidermis volume increasing, acne, anti-inflammatory, etc. 
     Particularly in cosmetics, applications can be offered for example in the ranges of moisturizers, cleansers, cleansing, anti-aging, antioxidant, protective, restorative (hands, feet, lips), contours (face, eyes, neck, lips), makeup skin care and for appendages, including eyelashes, lip products, solar products, remodeling, plumping, reshaping, lipofiling (e.g. on the hands, chest, breasts), hair products, etc. 
     Preferably, the present invention is directed to the  Globularia cordifolia  species which demonstrated particularly interesting results. 
       Globularia cordifolia  (or heart leaf globe daisy) is a small mountain rock plant which grows at altitudes of up to 2000 m. It survives at temperatures of −30° C. and thrives in poor chalky soils. It hails from the mountains of Europe and Central Asia. 
     According to other features, the extract for the invention use is preferably obtained by in vitro plant culture, more particularly by plant cell culture or by tissue culture from cellular or tissular lines from different plant organs. 
     The invention covers also the use of an extract obtained from the whole plant or specific parts of it, more preferably obtained from leaves. 
     The obtaining of extracts of plant origin by in vitro culture presents numerous advantages over the agro-industrial path (plant culture in open fields and subsequent extraction in factories). The obtained extracts are free of toxic substances (herbicides, pesticides, fertilizers, heavy metals and other contaminants, such as those that may come from plant parasite). Moreover, the strict control of in vitro culture conditions reduces the risk of spontaneous variation of the strain profile and ensures a reproducible secondary metabolites profile that corresponds to the molecules of interest sought, contrary to the culture in an open field where there is the problem of variability due to weather and geography. Furthermore, this technology overcomes obstacles such as the natural biological cycle of the plant and the seasonality of production of the secondary metabolites, thus allowing a better safety and supply rapidity. 
     In addition, the environmental impact is minimal avoiding consumption of arable lands and soils pollution. Furthermore, biodiversity is preserved since it takes only one plant or even a seed to initiate an in vitro culture. Finally, this technology offers the ability to direct cellular metabolism toward the production of molecules of interest (elicitation of the cultures) and to achieve some controlled and relatively rapid protocols in order to maximize yields. 
     Among the today existing technics in the field of in vitro plant culture, the followings can be used according to the invention: 
     Culture of undifferentiated cells: this method involves first the creation of highly proliferative cell lines in agar medium. These lines are then grown in liquid medium in order to substantially increase the biomass. At the end of the growth cycle and environmental conditions to be defined and optimized (searching for the appropriate elicitation parameters), the cell biomass will synthesize the molecules of interest. The culture is then stopped and extracted at the optimum time to obtain an extract, said to be of plant origin, containing a maximum amount of molecules of interest. Existing cell lines already available can also be used initially. 
     Culture of tissue or organ: this type of culture can concern the root part (“root culture”) or the aerial part (“shoot culture”). In this type of method, there are cultures that have been transformed by genomics bacteria  Agrobacterium rhizogenes  (root) or  Agrobacterium tumefaciens  (stems). Roots or aerial parts cultures thus transformed have a high growth rate and are genetically very stable. They are used to synthesize the molecules of interest after optimizing the elicitation parameters. These molecules are then extracted by conventional means. 
     In vitro micropropagation through vegetative multiplication, in particular somatic embryogenesis: the first step for this technique is to select a parent plant with optimal characteristics (in terms of growth and production of metabolites of interest). In embryogenesis, the next step is the induction of callus from explants from the parent plant. These undifferentiated cells can give rise to numerous somatic embryos that it will be possible to multiply and extend through successive cycles of culture. From the lines of the most proliferative and productive, seedlings are regenerated in a suitable medium and extracted in at the appropriate time for optimal production of metabolites of interest. The second step is the induction of stems with leaves from explants of the parent plant on a suitable culture medium thanks to its hormonal composition. An amplification phase of leafy stem is followed by a rooting phase to induce roots. It is then possible to regenerate plantlets in large quantities, to grow them in a suitable medium and extract the molecules of interest. 
     The present invention preferentially provides a method of manufacturing according to the first technique of plant culture of undifferenciated cells. 
     More particularly, the method is of type comprising from a line of undifferentiated plant cells:
         A step of pre-cultures for increasing the biomass,   A step of cultures in a bioreactor comprising a proliferation phase and then an elicitation phase, and   A recovering step of said extract.       

     According to other features:
         The step of pre-cultures comprises the completion of pre-cultures of increasing volumes, each pre-culture of smaller size for generating cellular biomass in sufficient quantities to inoculate the pre-culture of a larger size.   The subsequent step of cultures in bioreactor is achieved in a bioreactor inoculated with the biomass produced in the pre-culture step. After an initial phase of cell proliferation in a base medium, a medium of elicitation of secondary metabolites is added to the bioreactor. Culture is stopped when the desired level of secondary metabolites has been achieved. Preferably, to achieve this level, according to the invention, an elicitation medium deficient in sucrose and macronutrients is used.   The recovery step (or harvesting step) includes an extraction stage of this biomass by any physiologically acceptable solvent, or any mixture of these solvents. The extraction can be done by different known methods that can be combined: heat, maceration, decoction, infusion, pressure, leaching, ultrasonic, microwave, by lysing the cells by any chemical or physical appropriate method. Phase separation can be achieved by filtration or centrifugation. Alternatively, it is possible to extract the biomass with a supercritical fluid or subcritical. Alternatively also, it is possible to achieve a purification using an adsorbent resin, chromatographic methods or liquid-liquid partition.   According to a preferred embodiment, the cells are lysed in order to transfer the cell contents in water. More preferably according to the present invention, the lysis is performed by lowering to an acidic pH. After several filtrations, a sterile extract is obtained. Its pH is then adjusted advantageously according to the further use of the extract, for example at pH 4 for a cosmetic application as described below.       

     According to the invention, the cell line may be an existing line or a line created in a preliminary stage, with said step being performed separately in time. 
     According to the invention, the step of creating the cell line comprises the steps 1) induction of callus (clusters of undifferentiated cells), 2) selection of the best callus line and 3) transfer to cell suspensions and optimization of the growth parameters and production of molecules of interest (e.g. elicitation). 
     More particularly:
         1) The induction of callus can be done with all parts of the plant, including leaf, fruit, root, bud, seed, stem, branch, and meristematic tissues, in particular cambium; preferably according to the invention, the undifferentiated cell culture is achieved from the leaves of the plant.   2) The selection of the best lines, before a transfer in liquid medium, is performed according to the invention including in particular to the following criteria: high proliferative capacity, tender and friable texture, uniform color, and good dispersion in liquid medium and long-term stability of these parameters.   3) Optimization of secondary metabolites growth and production characteristics in liquid medium for the selected lines through the choice of the most appropriate media, in a first step to ensure rapid growth of the biomass and in a second time to allow maximum efficiency of secondary metabolites synthesis by cells at the end of exponential phase. This second phase corresponds to the culture elicitation and can be achieved in different ways among those available to the skilled person. These include: the addition to the cultivation of microbial fractions, stress molecules known to direct cells to their secondary metabolism, the application to the culture of a change in temperature or pH, or an osmotic stress, the use of an impoverishment of the environment, adding to the culture of adsorbent resins, which in addition to eliciting the compounds of interest can trap them. The preferred method of elicitation according to the invention is to impoverish the culture medium in macro-elements and sugar.       

     Therefore another object of the invention is a method for obtaining an extract of plant origin of  Globularia  in particular for implementing the use according to the invention by in vitro plant culture, comprising from a line of undifferentiated plant cells:
         A pre-culture step, designed to increase biomass;   A culture step in a bioreactor comprising a proliferation phase followed by an elicitation phase; and   A recovering step of said extract;       

     wherein the elicitation phase in the bioreactor step is achieved with a deficient in sucrose and macronutrients medium and in that said recovery step of said extract comprises an acid pH cell lysis. An original cell line for producing an extract of plant origin for implementing the invention is thus obtained, original and active in the searched fields as shown by the efficacy tests given below, preferably a cell line of  Globularia cordifolia.    
     Another object of the invention is thus the extract that can be obtained with the method of the invention as mentioned above. 
     A further object of the invention is a topical composition comprising a  Globularia  extract, and preferably a  Globularia cordifolia  extract, more preferably a  Globularia cordifolia  extract obtained by in vitro culture of undifferentiated plant cells as disclosed here-above according to the invention. 
     Such a topical composition may comprise a physiologically acceptable medium and additional actives (as mentioned thereafter in the galenic examples). The topical composition may be used for cosmetic applications or dermo-pharmaceutical applications. 
     The present invention also covers an extract of plant origin obtained conventionally by solvent extraction of the whole plant or specific parts of the plant, by supercritical fluid, micro-wave or ultrasounds, but comparative results showed superiority of the extract obtained from a cell line compared to a conventional solvent extract. These results are given below in the detailed description. The  Globularia  extract for implementing the invention can be used pure or diluted in a physiologically acceptable medium forming an excipient or matrix. 
     According to other advantageous features of the present invention, the extract of  Globularia  can be combined with at least one additional active ingredient, in order to preferably provide an end product with a wider range of properties. Additional active ingredients can be for example selected from whitening agents, anti-redness, UV sunscreens, moisturizing, humectant, exfoliating anti-aging, anti-wrinkles, thinning, volumizing, improving the elastic properties, anti-acne, anti-inflammatory, anti-oxidant, anti-radical, depigmenting, propigmenting, depilatories, anti-growth or promoting hair growth, peptides, vitamins agents etc. These active ingredients can be obtained from plant materials such as plant extracts or products of plant culture or fermentation. 
     More specifically, in a cosmetic composition, the extract of plant origin according to the invention can be combined with at least one of the compounds selected from the compounds of the B3vitamin compounds such as niacinamide and tocopherol, retinoid compounds such as retinol, hexamidine, α-lipoic acid, resveratrol or DHEA, peptides, including N-acetyl-Tyr-Arg-O-hexadecyl, Pal-VGVAPG (SEQ ID NO: 1), Pal-KTTKS (SEQ ID NO: 2), Pal-GHK, Pal-KMO2K and Pal-GQPR (SEQ ID NO: 3), which are conventional active ingredients used in topical cosmetic or dermo-pharmaceutical compositions.

     Cosmetic Treatment Method 
     The present invention also concerns a cosmetic treatment method to improve the general condition of the skin, comprising the topical application to the skin and/or the appendages of an effective amount of an extract of  Globularia  as recited above. 
     The extract of  Globularia  for the invention may be applied locally onto areas of the face, lips, neck, neckline, hands, feet, or body. One of the major advantages of the present invention resides in the ability whenever necessary or desirable to be able to apply local selective “gentle” treatments through this topical, non-invasive method of application. In the case of anti-wrinkle use for example it may be applied very locally using a syringe or micro-canula. 
     It is also possible, however, to consider a composition containing the extract according to the invention intended to be injected subcutaneously. 
     According to other specific features the cosmetic treatment method according to the invention can be combined with one or more other treatment methods targeting the skin such as lumino-therapy, heat or aromatherapy treatments. 
     According to the invention, devices with several compartments or kits may be proposed to apply the method described above which may include for example and non-restrictively, a first compartment containing a composition comprising the extract of  Globularia , and in a second compartment a composition containing another active ingredient and/or excipient, the compositions contained in the said first and second compartments in this case being considered to be a combination composition for simultaneous, separate or stepwise use in time, particularly in one of the treatment methods recited above. 
     The treatment method of the invention is particularly suited to prevent and/or treat skin aging by stimulating the detoxification reactions and/or cell regeneration through a hormetic type response, in particular for improving the radiance and/or transparency of the skin, for preventing and/or treating sensitive and/or reactive skins, for preventing and/or treating rednesses and/or preventing glycation of proteins. 
     The treatment method of the invention is also particularly suited for increasing and/or maintaining the number of dermal stem cells, and/or for increasing and/or maintaining the dermal macromolecules, in particular collagen and elastin, and/or for thus increasing the volume of the dermis (replumping), and/or for preventing and/or treating fines lines and wrinkles, and/or for firming skin, and/or for preventing hair loss and/or stimulation hair regrowth. 
     A) Example of Obtaining an Extract of Plant Origin According to the Invention by Undifferentiated Cell Culture of  Globularia cordifolia    
     I) Creation of a Cell Line 
       Globularia cordifolia  plants were obtained from seeds. 
     Leaves are collected, and thereafter cleaned and rinsed with water, and decontaminated and further rinsed. 
     a) Step of Induction of Undifferentiated Cells or Callus 
     Pieces of leaves are cut and placed on the surface of a nutrient agar, containing an assimilable carbon source, a solution of micro and macro-elements and a combination of adapted hormones and vitamins. This nutrient medium, thanks to its composition, will trigger the production of clusters of undifferentiated cells called callus at the site of healing of the leaf. Composition of the solid nutrient medium used (according to Gamborg): solution of macro-elements and micro-elements, saccharose, agar plant, plant hormones and vitamins. 
     pH is Adjusted Between 5,5 and 6. 
     This medium will be thereafter referred to the “basic medium”. This induction step lasts 1 to 4 months. Culture is made at 25° C. in the dark. 
     b) Stabilization and Selection Step of the Cultures in Agar Medium. 
     Callus stabilization is obtained after successive transplantations, every 3 weeks, on fresh medium. Stable and homogeneous cultures are thus obtained thanks to their phenotypic characteristics (color, friability, proliferation). 
     The selection is to choose the best callus cultures for the transfer in liquid medium, among the tens initiated earlier. The selected lines are characterized by high growth, a soft and crumbly texture, uniform color, good dispersion in liquid medium and stability of these parameters during the subcultures. 
     This step lasts from 6 months to 1 year. 
     c) Transfer in Liquid Medium and Optimization of the Production of Secondary Metabolites 
     The selected lines are transferred in liquid medium in order to optimize in an initial stage their growth parameters. 
     Cell growth and appreciation of the different phases (latence, exponential, stationary) are assessed by regular measurement of the percentage volume occupied by the culture cells or “packed cell volume” (PCV). 
     Different suspensions from the callus are placed on an orbital shaker, agitated at 110 rpm in the dark at 25° C. (in Erlenmeyer flasks each containing 100 ml of medium and 10 grams homogeneous texture, color and growth callus). Several media and hormone combinations are tested and compared in order to optimize the growth curve. The optimization of the initial density of the inoculum is also seeked for reducing the lag phase and thus the global duration of culture. 
     Furthermore, the selected initial density for the inoculum corresponds to a PCV of 10%. 
     The next step is to determine the optimal environmental conditions to direct the cellular metabolism toward the production of secondary metabolites at the end of the growth phase of the culture. These secondary metabolites and the other components of the extract medium as well, will participate in the activity of the extract obtained at the end. 
     Thus, in the medium, a high proportion of polar molecules were identified, including sugars, amino acids, primary metabolites, cinnamic acid and caffeic derivatives, and mixture of phenylethanoid glycosides. The phenylethanoid glycosides were chosen as indicators of secondary metabolites biomass production, their total dosage being easily achieved by the method of Arnow, a spectrophotometric method based on the oxidation of total polyphenols in alkaline medium by sodium nitrite and sodium molybdate (reading at 510 nm). Other classes of molecules are assumed to be present in the medium, such as flavonoids or iridoids but could not be identified. It is obvious that all of these molecules will be responsible for the activity of the final extract. 
     The elicitation chosen according to the invention to lead to the production of secondary metabolites is then to place the cells in medium depleted of sucrose and macronutrients, preferably in the same proportions. 
     This transfer phase in liquid medium and optimization of the parameters of growth and production can last from 6 months to 1 year. 
     After this step, a line giving the best results was selected. 
     It was subjected to a deposit under the Budapest Treaty on Oct. 27, 2010, with DSMZ (Deutsche Sammlung von Mikroorganismen and Zellkuturen GmbH) at Inhoffenstr. 7B, D-38124 Braunschweig, Germany, under the reference DSM25009. 
     The present invention covers an extract of  Globularia Cordifolia  species obtained from the cell line recorded under the number DSM25009. 
     2) Extract Obtaining 
     a) Production of Pre-Cultures in Bioreactors 
     Successive pre-cultures of the cell line selected of 1-liter, then 5 liter, and then 25 liter and finally 100 liter are realized. Each is seeded at 10% PCV and then grown to 50% of PCV. The cell biomass thus produced is used to inoculate the larger size culture. This stage can last from 1 to 3 months. 
     b) Transfer to Bioreactor Comprising the Elicitation Phase 
     A single use bag bioreactor (600 liters of total volume and 300 liters of total culture volume) is then seeded between 5 and 20% PVC. 
     The bioreactor is in particular equipped with:
         A rocker system for cell agitation and oxygenation, and for culture temperature regulation, preferably selected because being more suitable with regard to the fragility of plant cells compare to shearing of a conventional bioreactor;   A control tower equipped with different sensors (oxygen, pH and temperature) for the follow-up and the regulation of the culture steps;   A single-use sterile bag for the cell culture, equipped with different sensors (pH, oxygen), a filter for gas supply and exchange systems for sampling or inoculating sterile fluids.       

     After 10-15 days of culture in the bioreactor, the culture reaches a PCV of about 30 to 45%. The deficient medium is then added to trigger the production of secondary metabolites, including here phenylethanoid glycosides. The addition of fresh medium is 10 to 50% of the final culture volume. After 3-5 days, the culture was stopped at 35-50% of PCV, the phenylethanoid glycosides then being around 2 grams per liter in the culture. 
     This entire phase in bioreactor lasts 2 to 3 weeks. 
     c) Recovery of the Extract 
     The aim of this subsequent step is to produce an aqueous and clarified extract. 
     A cell lysis is achieved, leading to the release of secondary metabolites in the liquid phase. This lysis is carried out by acidification. A cascade filtration is then carried out, the first in-depth, followed by sterile filtration, to obtain the aqueous extract of the invention. This step is intended to stabilize the extract. 
     The extract obtained this way by plant cell culture is clear, colorless to pale yellow, to the contrary of the “classic” plant extract which is bright yellow, which is an advantage for a direct subsequent formulation of the extract in a cosmetic ingredient or other. 
     Variants of this Process Exist, Including: 
     1) For the extraction of the molecules of interest:
         The cell lysis step can be performed by biomass thermal treatment, for example by injecting steam into the biomass. It can also be made by grinding the cells with microbeads.   After the cell lysis step, it is possible to purify the crude extract, in order to enrich it in molecules of interest. According to this, biomass is first removed by filtration or centrifugation. The resulting clarified liquid phase is then contacted with an adsorbent resin, selected for its affinity with the molecules of interest. This resin is then loaded into a glass chromatography column. The resin is eluted with appropriate mixtures and the elution of the product concentrated.   The recovery of the extract according to the invention can be implemented using liposomes.       

     2) Regarding the Elicitation Mode of the Molecules of Interest: 
     The elicitation of compounds of interest can also be done by adding microbial fractions to the culture, by adding molecules of biological origin such as, chitosan, methyljasmonate, jasmonic acid, salicylic acid, by adding molecules of non-biological origin such as paclobutrazol, by applying to the culture a temperature variation, a pH variation, and/or an osmotic stress induced by a non-metabolizable sugar, such as mannitol, by using an even more drastic impoverishment of the environment in macro-elements and sugar, by adding to the culture adsorbent resins that in addition to elicitation of the compounds of interest production can trap them. 
     3) Instead of the cell line creation stage, a cell line according to the invention already prepared and preserved can be used. In this case, the step of creating the cell line is replaced by a conventional step of amplification of undifferentiated plant cells from said cell line existing first in agar and in liquid medium. 
     The invention method could also be achieved with the other species of  Globularia.    
     B) Example of Formulation of a Composition for Implementing the Invention which is an “Active Ingredient”, a Raw Material for the Cosmetics Industry 
     The active ingredient is a cosmetic composition containing the extract of plant origin of  Globularia cordifolia  dissolved in a dermatologically acceptable medium or matrix. This active ingredient is intended for the cosmetics industry for the preparation of cosmetics, such as creams, gels, etc. (see galenic examples given below). 
     The aqueous extract obtained in Example A) above may preferably be mixed at 20 to 80% with any hydrophilic matrix as a gel, an aqueous buffer, glycerin or other short-chain polyol physiologically acceptable. 
     For example, and for the achievement of the studies and galenic presented thereafter, an extract up to 33% was preferentially used. 
     Of course, a pure extract without excipient can also be used as the active ingredient. 
     C) In Vitro and Ex-Vivo Studies 
     The applicants have demonstrated a number of remarkable cosmetic effects of the  Globularia  extract which are presented below. 
     An aqueous extract prepared according to Example B) above, up to 33%, was tested in vitro and showed various cosmetic activities, concerning several areas of the skin physiology. The tests were all performed with 2% of such  Globularia cordifolia  extract. 
     Comparative Tests 
     First, the superiority of the extract obtained by cell culture versus a hydroalcoholic extract of the whole plant has been shown. These first tests were carried out by comparing an aqueous extract prepared according to Example B) above, up to 33%, diluted to 2%, compared to the hydroalcoholic extract of whole plant at an equivalent concentration in phenylethanoid glycosides. 
     1) Non-Enzymatic Glycation of BSA 
     This simple test reproduces in vitro a stress to which regular skin proteins are subjected: their functional alteration by a non-enzymatic glycation phenomenon. 
     The study model used is a bovine serum albumin (BSA), which is contacted with a physiological reducing sugar, the fructose, giving a spontaneous and slow reaction between the two molecules that can be accelerated by temperature. In this test, the BSA and fructose are incubated in the presence or absence of the test products at 50° C. for 7 days. The glycation end products have a natural fluorescence that can be quantified using a fluorimeter (λex=360 nm and λem=460 nm). 0.03% Aminoguanidine is used as a positive control of glycation inhibition. Data are given in Table 1 below.

     The positive control has a glycation inhibition of −85% versus the control. 
     2) DPPH Anti-Radical Test 
     The DPPH (1, 1-diphenyl-2-picryl hydrazyl) is a stable free radical which is widely used for the detection of free radical scavengers. This molecule by losing its radical character is converted to DPPH2 (1, 1-diphenyl-2-picryl hydrazine). This conversion is accompanied by discoloration (purple→yellow) which can be monitored over time by spectrophotometry at 517 nm. Control with no antiradical activity keeps a constant DO. 0003% of caffeic acid is used as a positive control for anti-radical activity. Data are given in Table 2 thereafter.

         3) Anti-Singlet-Oxygen Test       

     Molecular oxygen (O 2 ) plays a vital role as an acceptor of the respiratory chain terminal electrons. However, this metabolism and others, as well as external factors, such as UV radiations, lead to the occurrence of certain derivatives particularly reactive (singlet oxygen, hydroxyl radical, superoxide anion), which will cause oxidative damage to lipids, proteins and nucleic acids, even in healthy bodies. Singlet oxygen is one of these very energetic and highly reactive forms of oxygen. It is possible to produce experimentally in vitro singlet oxygen with dyes and UVA photons or visible light. The test presented thereafter uses the Rose Bengal, a dye and visible light. The purpose of this test is to evaluate the degradation of uric acid by singlet oxygen formed from the Rose Bengal, under the action of visible light. The visualization of the production of singlet oxygen is obtained by following the destruction of uric acid at 292 nm. In the presence of a compound capable of neutralizing singlet oxygen, this destruction will be slowed. The caffeic acid at 0002% is used as a positive control of an anti-singlet-oxygen activity Data in Table 3 below.

     These three tests show the cosmetic interest of the  Globularia  extract obtained by cell culture, which also has a much higher efficiency compared to the hydroalcoholic extract obtained from the plant. 
     Studies on the  Globularia cordifolia  Cell Culture Extract 
     These studies were carried out with an aqueous extract prepared according to Example B) above, up to 33%, diluted to 2%. 
     Protection of Keratinocytes in Culture by the Extract of the Invention Facing a Double Stress, Mechanical and Oxidative 
     Confluent keratinocytes layers were put in contact (test) or not (control) with 2% of the extract of the invention to in a culture medium for 24 hours. The layers were then “wounded” in a reproducible manner and after immediately exposed to UVB to assess their ability to resist to two stresses commonly suffered by the skin. The recovery of cell layers was then evaluated by image analysis, by quantifying the surface free of cells (results in Table 4 below).

     The visual observations showed that the control layers underwent a profound alteration of their integrity (with some cell death) and had a great difficulty to recolonize the injured surface. To the contrary, the layers that were in contact with the  Globularia cordifolia  plant cell extract were less altered and re-form faster a dense and uniform layer. 
     This preliminary test illustrates well the hormetic phenomenon at work in the presence of the extract of  Globularia . Presumably, the cells pre-contact with the extract resulted in the establishment of a number of lines of defense, including antioxidant, before stress, then used by the cells to counteract the deleterious effects of stress and regenerate a normal cell layer. 
     This hormetic effect of the  Globularia cordifolia  extract has been in vitro demonstrated and quantified by studying the following three distinct axes (4-6). 
     4—Preservation of Epidermal Progenitors 
     Principle 
     The epidermis regenerates continuously in order to produce an effective skin barrier. This effect declines with age. The cells at the start of this process are called stem cells or progenitor cells. They are rare but keep their potential to regenerate because of the quality of their molecular links binding them to their immediate environment. 
     Harmful treatments such as oxidants alter the environment of these cells and make them evolve into a different phenotype, causing a change in their subsequent ability to proliferate. In vitro these cells, having lost their proliferative capacity, form small colonies, which may be invisible to the naked eye, the daughter cells in these colonies being relatively large. To the contrary, progenitor cells can multiply extensively in order to regenerate the skin and produce larger colonies with smaller cells. This potential for regeneration and therefore progenitor cell density in a culture is measured by the cloning efficacy method. This method involves counting the number of colonies visible to the naked eye after seeding cells at low density and culturing for a specific time. The number obtained is used as a measure of the progenitor vigor of the initial cell population. 
     Confluent human epidermal progenitor keratinocytes were placed in contact with an optimum medium to force their conversion into differentiated keratinocytes (so to make them lose their progenitor phenotype) in the presence or absence of the  Globularia cordifolia  extract. Following the contact, the cells of the two series were reseeded at a concentration of 1000 cells/25 cm2 (n=5) into the differentiating medium. 
     Results 
     After culturing for 12 days, the number and size of the colonies can be measured after fixation and staining. The results show that the control cases presented 5.4±1.5 colonies/1000 seeded cells and that the colonies were small in size. In parallel, contact with the  Globularia cordifolia  extract gave 2.3 times more colonies (12.6 colonies ±4.3 colonies/1000 seeded cells; +133%; p&lt;0.01) than the control and the colonies were larger in size. 
     This shows that the  Globularia cordifolia  extract prevents progenitor cells from converting to a differentiated stage and maintains their proliferative capacity. It preserves according to this the epidermal capacity to regenerate itself. 
     5—Stimulation of the Energetic Potential 
     a. Sirtuin 1 
     Hormetic effects such as calorie restriction or contact with hormetic molecules increase sirtuin enzymes and the lifespan of different organisms. The sirtuins act particularly on FOXO factor deacetylation and prevent triggering of the production of apoptotic proteins. The sirtuins also stimulate cellular anti-oxidant defenses and purification mechanisms (detoxification) and help to preserve mitochondrial function and therefore energy production. This increases survival and resistance to stresses. 
     Human keratinocytes were cultured in the presence or absence of the  Globularia cordifolia  extract for 6 days and were then grinded and the intracellular levels of sirtuin-1 were measured using an ELISA method. Results were standardized by parallel measurement of total protein (BCA). Results are given below in Table 5.

     In parallel, abdominal skin explants (58 years female) received a topical application daily for 6 days of a cream containing the  Globularia cordifolia  extract of the invention or its placebo (ex vivo test). After this treatment, the explants were prepared and labeled with fluorescent antibodies to quantify sirtuin-1. This quantification uses an image analysis system after photography (50 photos/per case). The results are given in Table 6 thereafter.

     b. Creatine Kinase 
     Creatine kinase is a ubiquitous enzyme which exists in two isoforms in the skin. It is used to store energy in cells and enables tissues to respond to urgent energy requirements. This enzyme converts creatine into phosphocreatine using ATP which is converted back to ADP. When necessary, the enzyme works in the reverse direction and returns energy. Its activity falls with age as it is one of the preferred targets of reactive oxygen groups. Maintaining and increasing the activity of this enzyme is therefore desirable. 
     Human dermal fibroblasts were placed in contact with the  Globularia cordifolia  extract according to the invention for 3 days. The cells were then exposed without said extract to an oxidative stress (hydrogen peroxide). After a further 3 days&#39; contact with the  Globularia cordifolia  extract, the cells were again exposed to the same oxidative stress before being homogenized to measure residual intracellular creatine kinase activity. Activity was measured from the production of ATP from phosphocreatine and ADP. ATP is then measured from an enzymatic reaction leading to the formation of NADPH, readed at 340 nm. Results were standardized by measuring total protein (BCA). Results are given below in Table 7.

     c. Mitochondrial Membrane Potential 
     The mitochondrion is a major site involved in the formation of reactive oxygen groups which, over time, interfere with the functioning of its respiratory chain. This causes a decrease in mitochondrial membrane potential (A′P), causing a reduction of the ATP production. 
     A fall in this membrane potential is a warning sign of ageing and cell death and it is therefore essential that this be maintained to preserve the mitochondrial ability to produce ATP. Membrane potential was measured using a specific label sensitive to mitochondrial proton micro-variations. The label exists in two forms, monomeric and polymeric, which have different emission spectra. A high membrane potential promotes the polymeric form. An increase in the monomer/polymer ratio (520 nm/590 nm) produces therefore a fall in Δψ. 
     A high ratio is therefore less conducive to cell survival than a lower ratio. 
     The same fibroblast cultures than used for creatine kinase there above were used. The results are given below in Table 9.

     This study complements the two previous studies to demonstrate the ability of the  Globularia cordifolia  extract of the invention for anti-aging prevention. It stimulates spontaneously the amount of sirtuin1. It maintains the activity of creatine kinase and protects the production of ATP in response to an oxidative stress. 
     6—Combatting Noxious Products 
     a. Endogenous Peroxides 
     One of the indicators traditionally used to assess the vitality of a cell population is the level of oxidative stress. 
     This factor can be measured reliably using a probe called DCFH-DA, whose characteristic is to fluoresce in contact with peroxides once it entered the cell. 
     Protocol 
     Confluence human keratinocytes were placed in contact or not (negative control) for 24 h with the  Globularia cordifolia  extract until they grew to confluence. The cells were then exposed to and metabolized the DCFH label in a buffer. The label can then react with both intracellular peroxides. The medium was then replaced with one containing or not the  Globularia cordifolia  extract and the oxidizing agent model hydrogen peroxide (neither the medium nor the  Globularia cordifolia  extract reacts directly with H 2 O 2 ). Fluorescence was read in order to estimate the level of the intracellular peroxide which had reacted with the label. The number of cells was quantified using a nuclear labeling method (Hoechst 33258). The results are given below in Table 10.

     The  Globularia cordifolia  extract according to the invention protects intracellular content from the rise in peroxides induced by hydrogen peroxide. This result reflects a reduction of the damage generated by free radicals or reactive oxygen species following oxidative stress in the presence of the  Globularia cordifolia  extract. 
     b. SOD and Catalase 
     Antioxidant enzymes such as catalase or SOD, produced by our bodies, as well as antioxidants, vitamins E and C, carotenoids, etc. which are drawn from our food, help to fight against the harmful effects of free radicals and reactive oxygenated species. So there is a clear interest in increasing their number by stimulating their synthesis. 
     A preliminary test on the antioxidant skin potential had shown that human keratinocytes treated with the hydrogen peroxide, a model of oxidative stress, increased their intracellular activity of SOD (superoxide dismutase) by 22%*(p&lt;0.01) compared to the negative control in the presence of the  Globularia cordifolia  extract. 
     *Positive control Trolox at 0.012%: SOD 21%; p&lt;0.01. 
     In addition, explants of abdominal skin (woman, 58 years) received 1 topical application daily for 6 days of a cream containing the  Globularia cordifolia  extract or its placebo. 
     At the end of this treatment, the explants were prepared and labeled with anti-SOD fluorescent antibody on the one hand or anti-catalase on the other. Quantification was performed using an image analysis system after taking photos (50 photos/case). The results are given in Tables 11 and 12 below.

     The  Globularia cordifolia  therefore stimulates SOD and catalase production, independently of any stress. These “spontaneous” stimulation, found in Hormesis, enable the skin to prepare appropriate defenses against stresses which may occur later. 
     c. Proteasome and Glycation 
     Proteins which are damaged by glycation, oxidation (carbonylated proteins) or conjugation with lipid peroxides tend to accumulate in the cell during ageing. They are removed routinely by the proteasome which reduces their harmful effect on cellular homeostasis. The activity of the proteasome, however, is reduced by these accumulations, and by accumulation of lipofuscin, a lipoprotein waste product, or in time, leading to further increased amounts of damaged proteins by a vicious cycle. 
     Maintaining the activity of the proteasome is one of the beneficial consequences of hormesis as it supplements the cells anti-ageing defense armamentarium. It helps to remove waste which accumulated in the cell, leading to the production of pre-inflammatory substances which opacify the cells. 
     Human dermal fibroblasts were placed or not (negative control) in contact with the  Globularia cordifolia  extract until they grew to confluence. The  Globularia cordifolia  extract was then removed and the cells were exposed to the oxidant model, hydrogen peroxide, to produce accelerated ageing. After this stage, the cells were again exposed to the  Globularia cordifolia  extract for 3 days and then were reseeded and subjected to a further oxidative stress to amplify the effect of the initial stress. The cells were then homogenized and the residual proteasome activity measured by monitoring cleavage of a model fluorescent peptide. Results were standardized by parallel measurement of protein. Results are given thereafter in Table 13.

     The anti-glycation effect of the extract of  Globularia cordifolia  was studied using a protein model, BSA and a natural reducing sugar, fructose which glycates, i.e. binds, to the protein in a non-enzymatic manner. The product of this binding is fluorescent and is monitored with a recording system. Results are given below in Table 14.

     d) Glutathion 
     In addition to its well-known antioxidant role, glutathion is the most important detoxification element of the body and the principal agent of the good health of the body. It binds to toxins such as heavy metals, solvents and pesticides, and transforms them into water-soluble compounds that can easily be eliminated in bile or urine. 
     Glutathion synthesis was spontaneously stimulated in keratinocytes in the presence of the cell culture extract of  Globularia cordifolia: + 49%* (p&lt;0.01) compared to the negative control who did not receive the extract. 
     * Positive control Trolox at 0.012%: GSH: 53% (p&lt;0.01) 
     The hormetic type effect (“hormesis-like”) of the extract according to the invention has thus been shown in particular in 3 directions:
         A direct strengthening of the molecules and metabolite pathways that contribute the cells to be more responsive to an ulterior stress (sirtuins, SOD, catalase, glutathion);   By direct protection of the energy potential of the cell and its integrity against oxidative stress (creatine kinase, mitochondrial potential, proteasome, level of peroxides or glycated proteins) and   By maintaining the skin regenerative capacity, promoting the progenitor phenotype and therefore proliferative in cells in charge of this function.       

     Studies on Dermal Stem Cells 
     These studies were carried out with an aqueous extract prepared according to Example B) above, up to 33%, diluted to 1%, 2% or 3%. 
     As study model, dermal stem cells from the follicular dermal papilla were used (HFDPC). They were drop seeded to make a “Hanging drop” type culture, in the presence or absence of the  Globularia cordifolia  extract (n=43 drops/box). 
     The maintaining of the phenotype of stem cells in the dermal papilla through the Sphere-forming properties and specific markers, Nestin and SOX2, has been studied. 
     Sphere Forming Properties 
     The capacity of cells to in three dimensional spheres is a characteristic of dermal stem cells phenotype. The loss of this phenotype figures differentiation of these cells and the remoteness of stem feature. When a culture shows a greater number of spheres that another, it means it is richer in skin stem cells. 
     The cells are left in contact with the extract for the time for the spheres to be formed. After adhesion of the spheres, their number is counted. The results are presented in Table 15 below.

     E) In Vivo Studies 
     The tests were achieved with the cream of above example 1. 
     Principle 
     The efficacy study of the cosmetic cream containing the  Globularia  extract according to the invention was performed on a panel of 20 volunteers with dull skin to assess the improvement in facial complexion; on another panel of 22 volunteers with reactive skin to demonstrate an improvement in this effect and on a panel of 14 volunteers with visible signs of ageing (wrinkles, spots, etc.) to assess the amounts of SOD and carbonylated proteins present. 
     Several complementary methods were combined during this study:
         Analysis of clarity and redness of the complexion on standardised photographs.   Analysis of skin transparency by the Transluderm™.   Analysis of skin shine and matting by the Goniolux™.   Evaluation of reduced over-reactivity of the skin with the Neurometer®.   Evaluation of the amounts of SOD and carbonylated proteins on adhesive tape strips taken from the cheek.       

     Protocol 
     Specific Inclusion Criteria for the Different Studies 
     Women with a dull, tired and uneven complexion were included in the complexion study. 39% of these women were smokers, a factor which is very often associated with a dull complexion. 
     In the skin reactivity studies, the volunteers were selected on the basis of a positive response to the stinging test and from a questionnaire revealing a sufficient sensitivity score. The volunteers were required to follow a 15-day washout period (using the placebo). 
     In the ageing signs study, the 14 volunteers were selected if they were over 45 years old and had multiple signs of ageing: lines, blemishes or redness. As in the previous study, a washout period was required. 
     For the 3 tests, no hormonal changes were allowed during the 3 months before the tests and during the tests themselves (no change in contraceptive, hormone replacement or curative therapy). 
     Subjects had to use only the cosmetic products provided during the study. 
     Types of Study and Duration 
     The studies were conducted single blind using non-invasive measurements on:
         20 volunteers with dull skin (mean age 34 years old [range 20 to 48 years old]) who were randomized to apply the cream containing the  Globularia cordifolia  extract to half of their face and the placebo cream to the other half of their face.   22 volunteers with reactive skin (mean age 44 years old [range 25 to 64 years old]) who were randomized to apply the cream containing the  Globularia cordifolia  extract to one forearm and the placebo to the controlateral arm. The creams for this panel were slightly richer (2% glycerine added) because of the subjects&#39; reactive skin.   14 volunteers with physical signs of ageing (average age 57.5 years old [range 47 to 71 years old]) were randomized to apply the cream containing the  Globularia cordifolia  extract to one cheek and the placebo cream to the controlateral cheek.       

     The cream containing the  Globularia cordifolia  extract or the placebo was applied by massaging into the skin twice daily for 2 months. 
     The study is summarized in the diagram below.

     1.1 Study of Facial Complexion 
     Analysis of Clarity and Redness from Standardised Photographs 
     A photography system, the HeadScan (Cosm&#39;O Laboratory) was used to take identical photographs on the two occasions. The system uses a high definition digital camera equipped with flashes and filters to obtain cross-polarized light taking a shine-free image. 
     For each half of the face, 5 areas were automatically extracted with the FrameScan™ software to calculate the Clarity (L*) and Redness (a*) indices. 
     The results are given in the Tables 18 and 19 below.

     In parallel, redness complexion of these volunteers increases on the placebo side during the test by +17.1%; (p&lt;0.01). This may have been due to the different weather conditions between the two measurement times. Application of the  Globularia cordifolia  extract cream however limited this increasing trend in redness. The difference between the two sides was in favor of the side treated with the  Globularia cordifolia  extract cream: −13.4%; (p&lt;0.01) 
     From the results obtained for these two parameters, fewer imperfections and redness with a more even and radiant complexion for the face can be deducted. 
     Analysis of Skin Transparency by TRANSLUDERM™ 
     Skin transparency was assessed by an instrument developed by Orion Concept: the Transluderm™. This instrument consists of a 17 mm radius plate, the center of which contains a continuous spectrum white light diode which illuminates the skin. Sensors are arranged every 1.5 mm in all four directions, recording the amount of light given off by the skin. An image is taken using a high resolution camera and image analysis is performed with dedicated software. A “maximum propagation distance” parameter of light conducted through the skin is obtained from this. 
     Understandably, transparent skin conducts light further. 
     Results are given in table 20 below.

     The light was found to travel a far greater distance (+52.7% vs. placebo) indicating that skin transparency is greatly improved after applying the  Globularia cordifolia  extract cream. The previously observed effects are thus reinforced. 
     Analysis of Skin Radiance by the GONIOLUX™ 
     The Goniolux™ (Orion Concept) was used to assess shine and matting parameters. This instrument quantifies the interaction between light projected onto the skin (incident light) and the behaviour of the light returned by the skin (reflected light). Reflected light is measured using multiple sensors in all directions in a three-dimensional space. The light reflected can be broken down into specular (mirror effect) reflected light and diffuse reflected light (halo effect). The skin appears more youthful and more beautiful when the light returned is soft with less shine and more matting (halo). 
     Results are given below in Table 21.

     Application of the  Globularia cordifolia  extract cream for 2 months produced a beneficial mattifying effect consisting of reduced shine (−9.1%; p&lt;0.02 vs. T0), producing an improvement in results for this parameter (+5.2%; p&lt;0.07 vs. placebo) combined with an increasing trend in the matt appearance (+17.9%; p&lt;0.01 vs. T0). 
     Improvement in these 2 parameters produces a face which is smoother and softer in appearance. 
     1.2 Study of Skin Reactivity 
     In order to examine the improvement in volunteers&#39; skin reactivity, an instrument called the Neurometer® was used, this instrument being used in medicine for early detection of hyper or hypo-reactivity. 
     The Neurometer® can be used to provide both a quantitative and qualitative characterization of changes in skin sensitivity. 
     The instrument stimulates nerve cells by delivering a small current to the skin until the volunteer detects something (the procedure is entirely painless). This corresponds to the individual current perception threshold (or CPT=Current Perception Threshold). 
     If a person can perceive currents at a higher intensity than other people, this indicates that they have a higher skin tolerance to stresses and a less reactive skin. Conversely, low perception currents indicate a more reactive skin. 
     There are several types of nerve fibers, (Aβ, Aδ and C fibers) which can be excited by different frequency currents. The 3 types of nerve fibers carry different information. Because of the experiences of volunteers in the inclusion tests, forearm type Aβ fibers as the model in this study was used. These large diameters, rapid conduction fibers, carry skin touch, pressure, vibration and distension information. They are associated with four types of mechano-receptors: Meissner&#39;s corpuscles, Ruffini&#39;s corpuscles, Merkel&#39;s disks and Pacini&#39;s corpuscles. 
     Measurements were performed automatically and double-blind in this study, ensuring very reliable results, which are particularly important for this type of individually dependent, subjective sensation. Results are given in below Table 22.

     The results show a slight and insignificant deterioration in the perception threshold on the placebo site which, as a result of this fall, makes the skin more reactive than at T0. 
     Conversely, on the site which was treated with the cream comprising the  Globularia cordifolia  extract, the perception threshold rose very significantly by +23.6%; (p&lt;0.01) compared to placebo. This indicates a fall in skin reactivity after using the  Globularia cordifolia  cream according to the invention. 
     1.3 Studied SOD and Carbonylated Proteins on Adhesive Tape Strips 
     A test was conducted on volunteers with visible signs of ageing (N=14) to confirm the stimulation of SOD production seen in culture cells and in explants treated with the  Globularia cordifolia  extract cream. 
     After applications of the cream containing the  Globularia cordifolia  extract onto the cheek for 2 months, SOD activity measured from adhesive tape strips taken from the cheeks showed a marked improvement in activity of +19% on the site of the  Globularia cordifolia  extract cream compared to a fall of 13% on the controlateral placebo site. The difference of 32% is significant (p&lt;0.0/). Furthermore, the amounts of carbonylated proteins found on the stratum corneum cells removed by adhesive tape strips in the same study were also measured using the method of FUJITA et al, (2007). Carbonylated proteins were identified directly on the adhesive tape strips using an FTZ fluorescent label and measured with a fluorescence reader. Data was standardized by parallel measurement of total protein. The results are given below in Table 23.

     These results show that less carbonylated protein was collected onto the adhesive strips on the side which was treated with the  Globularia cordifolia  extract cream and that this difference was significant compared to the placebo site (−18% on the placebo side; (p&lt;0.01). 
     Thus, after 2 months&#39; application to skin with visible signs of ageing, the  Globularia cordifolia  extract cream is able to improve SOD activity and reduces amounts of carbonylated proteins present. Combined with the observations in the tests on dull skin, it can be conclude that the  Globularia cordifolia  extract cream has stimulated the skin&#39;s defences and restored its transparency and radiance. The improvement in cleansing capacity has helped to reduce reactiveness, making the skin less receptive to future stresses, as being immunized. The  Globularia cordifolia  extract cream therefore acts as a genuine anti-ageing vaccine.
