Definitions

• composition against ageing of the intimate area skin Composition against ageing of the intimate area skin
• the present invention relates to a cosmetic agent, a composition against ageing of the intimate area skin, and the use thereof.
• the present invention belongs to the following classes of the International Patent Classification A6lKlb, A61K8/14, A61Q19/08, A61Q90/00,
• a technical problem solved by the present invention is the obtaining of a composition intended for intimate area skin care and prevention of ageing, i.e. loss of elasticity.
• the present invention provides a pH value of the intimate area of 3.8-4.5, provides a reduction of the possibility of infection, an increase in the sensation of skin hydration, facilitation of intimate relations, depigmentation.
• European Patent No. EP2648739 relates to a multi-purpose gel for the dryness of the vagina with direct and delayed effect.
• the gel comprises colostrum fraction enriched with immunoglobulin, growth factors, chemotactic factors, and antimicrobial/antiviral factors. This gel is used in the treatment of vaginal dryness and an anti-ageing effect is not indicated.
• the International Patent Application Publication WO 2017/069793 relates to the compositions of the vaginal gel and methods for use thereof.
• the gel listed in this international application solves the problem of vaginal dryness.
• the anti-ageing effect is not attributed to the gel, but is indicated only as one of the effects of vitamin E.
• This application addresses the problem of vaginal dryness by a viscous pharmaceutical composition containing a water-soluble gel containing niacin and/or L-arginine.
• L-arginine is listed as an ingredient or as an alternative ingredient of the gel.
• vaginal preparations used for the treatment of vaginal dryness, but none of them deals with the problem of ageing of the intimate area.
• the preparations of the prior art are applied vaginally, while the composition according to the present application is applied to the skin of the intimate area outside. Treatment that involves the application of the composition to the intimate area outside, rather than vaginal application, is more acceptable to women.
• the present composition prevents changes in the skin, thereby contributing to improved circulation, reduced pigmentation, skin hydration, and through circulation, gives effects in the vagina.
• the composition according to the present application prevents the skin from thinning by stabilizing the DNA strands of the skin cells and by stimulating microcirculation with antimicrobial activity and under the conditions of a well-defined pH value (pH 3.8-4.5).
• This composition provides the pH value of the intimate area of 3.8-4.5, thus reducing the possibility of infection, in addition, the sensation of skin hydration increases, intimate relations are facilitated, depigmentation is achieved.
• the pH value of female intimate area increases, by ageing, up to pH 6.
• the present composition affects the alteration of the pH of the intimate area skin by readjusting the pH to the optimal value i.e., 3.8-4.5, preferably 4.0-4.4.
• the composition can be used for showering (cleanses the skin, hydrates the skin%), instead of the lubricant, it reduces scar tissue and has a hypoallergenic effect.
• the present invention advantageously avoids the leakage effect of the composition, since the composition is not in the form of an aqueous solution, but is enclosed by liposomes.
• intimate area/zone refers to the female external reproductive organs and the perineum, i.e. labia majora and labia minora, the clitoris, the vaginal opening and the perineum.
• the skin of an intimate area that includes the female external reproductive organs has a number of specificities and specific issues that are expressed only in this area.
• This area of the skin has its own specific pH of 3.8-4.5 which is lower than the pH of the other parts of the skin, in order to represent defense against various infections.
• epithelium alters from the keratinized stratified squamous, to the stratified squamous, and that line of epithelium alteration represents the risk point for the action of adverse agents, toxins and microbes.
• This area of the skin is highly exposed to mechanical lesions and damage of the surface parts of the skin.
• Alteration of skin properties of this zone, i.e. ageing thereof, pH alteration and the reduction of thickness and elasticity lead to a direct negative impact on the female reproductive and general health.
• the present treatment provides optimal pH and serves as the first defense against infections, and active ingredients that are incorporated into phospholipid liposomes lead to increased tissue circulation, considerable elimination of free radicals in cells, stabilization of DNA strands of the cells and high hydration.
• This composition provides the pH value of the intimate area of 3.8-4.5, thus reducing the possibility of infection, in addition, the sensation of skin hydration increases, intimate relationships are facilitated, depigmentation is achieved.
• the pH value of female intimate area increases up to pH 6.
• the present composition affects the alteration of the pH of the intimate area skin by readjusting the pH to the optimal value i.e., 3.8-4.5, preferably 4.0- 4.4.
• composition comprising: L-arginine, turmeric, hyaluronic acid or a salt thereof, lactic acid and vitamin E as active ingredients encapsulated in liposomes.
• the present composition may further comprise lecithin, glycerol and/or one or more preservatives, e.g., potassium sorbate and/or sodium benzoate.
• preservatives e.g., potassium sorbate and/or sodium benzoate.
• the present composition may additionally contain vitamin C, niacin and/or lysine.
• vitamin C niacin and/or lysine.
• L-arginine, a white turmeric derivative, hyaluronic acid or a salt thereof, lactic acid and tocopherol (vitamin E) are present.
• the present composition contains up to about 20% arginine, which is accomplished by the use of liposomes within which the active substances of the present composition are contained.
• liposomes allows the active ingredients to reach the stratum comeum of the skin, rather than the circulation.
• the composition is in the form of a gel.
• L-arginine The effect of L-arginine on the skin has been confirmed by many scientific papers and it has been found that it stimulates circulation in the skin, stimulates the growth hormone effects, stimulates fibroblasts and prevents skin thinning. It also prevents the action of free radicals before they damage the DNA strand, thereby prolonging the life of the cells. L-arginine also helps in wounds healing and is used in some cosmetic treatments for facial skin care, but what makes our preparation unique is the L-arginine concentration of about 20%, which is not present in any known skin care product.
• Turmeric has an effect on the prevention of pigmentation of the skin, has significant antimicrobial effect and is one of the strongest antioxidants.
• Hyaluronic acid is known and widely used in cosmetics as an important skin hydration factor and collagen stimulator.
• Tocopherol is a very common ingredient in the preparation that increases the activity of the enzymes in skin cells, hydrates skin and has an antioxidant effect.
• Lactic acid is very important in this preparation because it enables achieving ideal pH, but it also has a positive effect on the exfoliation of dead skin layers, the reduction of pigmentation and the strengthening of the skin texture.
• Phospholipid liposomes which were used as carriers of the active substances.
• Phospholipid liposomes have the same structure as the cell membrane, so they adhere to it, and have the effect of preventing the loss of water from the cells. Also, their structure allows the transport of active substances into the deeper layers of the skin where they actually achieve their biological activity and allow large molecules, such as hyaluronic acid, to be absorbed and transported through the cell membrane which is otherwise impossible to achieve by other types of carriers.
• the present composition represents a combination of ingredients that gives a synergistic effect over to the individual ingredients in relation to the following biophysical parameters of the subjects skin: EC-as measure of skin moisture, TEGV-trans-epidermal water loss as a measure of barrier properties of the skin, the surface lipid content, El-erythema index, and MI-melanin index.
• composition against ageing of the intimate area skin was prepared in the form of an intimate liposomal gel with the following composition: Ingredients per 50 CC (All material is of food quality grade)
• Liposomes were formed automatically by mixing phospholipids from lecithin with a solution of L-arginine in water. The system was formed using high shear mixing and high pressure production processes. (source: Liposomes, a practical approach, edited by Vladimir P. Torchilin et al, Oxford university press, second edition).
• source Liposomes, a practical approach, edited by Vladimir P. Torchilin et al, Oxford university press, second edition.
• the liposomal intimate gel described in Example 1 was applied to women aged 25 to 70 years in the gynecological ordination Medison plus, Belgrade, Serbia, under the control of Dr Sci med. Amira-Mima Fazlagic. Over the course of two years, this gel was tested in 80 women and in the younger group there was a significant improvement of the blood circulation sensation in the intimate area and the improvement of sensitivity during intimate relations, and in the older group there was a significant increase in the hydration and the blood circulation sensation in the intimate area. In the group of women from 55 to 70 years, after the regular use of the preparation, the tissue quality improved and the intimate relationships that were previously impossible due to dryness were enabled.
• Optimal pH of the intimate area skin is 4.0-4.4.
• the total number of subjects of all age groups with normal pH before the use of the preparation was 30.
• the total number of subjects with normal pH of the intimate area skin after 30 days of daily use of the preparation was 66 (Fig. 1).
• Number of subjects by age groups with normal pH of the intimate area skin after 30 days of daily use of the preparation A sensation of better hydration of the intimate area skin after 30 days of daily use of the preparation by age groups:
• Fig. 4 Improvement of the quality of intimate relations after 30 days of daily use of the preparation is shown in Fig. 4 and in the following table, which contains the number and percentage of women with improvement of the quality of intimate relations.
• 30 had normal pH of the intimate area skin (4.0-4.4), representing 37.5% of the total number.
• 82.5% of all subjects had normal pH of the intimate area skin. This result shows a statistically significant change in the achievement of normal pH by using the preparation. The most pronounced effect was achieved in older age groups where, due to loss of estrogen, the greatest problem with optimal pH value occurs.
• the efficacy was studied after the application of the preparation on the healthy skin of the subjects-volunteers.
• the investigated preparation statistically significantly increases the skin moisture after 7 days of application (in relation to the basal value) and the hydration level is maintained at a statistically significant level throughout the test period (4 weeks of application). All the time during the test period, the preparation had a statistically significant effect on TEGV in terms of its decrease in relation to basal value, which indicates a positive effect on the barrier properties of the skin.
• the surface lipid content is increased on the skin treated with the tested preparation from the 7 th day of application, during the entire period of administration, indicating the formation of a thin phospholipid film on the surface of the skin as a result of the application of liposomes to the skin.
• the increase in MI and El indicates the anti-irritant effect of the examined preparation. All the measured parameters showed statistically significantly better results for the examined preparation compared to the preparations containing individual active principles, significantly better results than a sum of the effects of individual preparations, indicating the synergistic effect of the selected active principles.
