Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to an anti-aging composition, a skin care product and a preparation method thereof. Background Art

[0002] As we age, cell aging and death accumulate, and the combined influence of endogenous factors such as ultraviolet rays, oxidation, and inflammatory stress causes the gradual reduction of collagen and elastin in the skin, changes in structure and function, weakening of the skin barrier, and destruction of basal proteins, which further lead to sagging skin and wrinkles. In other words, the firmness and elasticity of the skin barrier are closely related to the degree of skin aging.

[0003] The skin barrier includes six dimensions: microbial, physical, chemical, immune, neural, and antioxidant barriers. To enhance the skin barrier, we can focus on these six dimensions, by maintaining the skin microecology, enhancing the skin stratum corneum (improving the support, stability, and elasticity of the dermis), regulating the local acid, alkali, and electrolyte homeostasis of the skin, maintaining the normal balance of inflammation-immune system, and anti-oxidation. Among them, the physical and antioxidant barriers are particularly relevant to anti-aging, and the stability of the skin barrier is the basis for supporting the firmness and elasticity of the face, which can also achieve the purpose of anti-aging. Better, compared with traditional anti-aging methods such as lifting, hydrating, and filling wrinkles on the surface, the anti-aging effects of enhancing the skin barrier, endogenous antioxidants, and endogenous and exogenous supplementation of skin matrix proteins are more fundamental and long-term.

[0004] However, many current anti-aging products can only achieve surface firming, wrinkle filling, and lifting effects, which do not last long and cannot truly affect the state of skin basal cells and the content and density of intrinsic elastin and collagen, or they use medical beauty methods that are costly and have a long recovery period.

[0005] For example, CN118178253B discloses a moisturizing and anti-aging composition and a preparation method thereof, which belongs to the field of cosmetic technology. The ingredients of the composition include bougainvillea white flower peptide, scutellaria baicalensis peptide, resurrection grass extract, sea fennel extract, avocado extract, sodium hyaluronate, propylene glycol, etc.; among them, bougainvillea white flower peptide, scutellaria baicalensis peptide and resurrection grass extract are extracted by a special extraction method of multi-stage enzymatic hydrolysis or fermentation, which can greatly improve the moisturizing and anti-aging effects of the extract.

[0006] CN118304242B discloses a skin anti-aging plant extract composition and a preparation method thereof. A skin anti-aging plant extract composition, using lactic acid-glycolic acid copolymer to wrap plant extract, then mixed with chitosan, Tween 80 and polyvinyl alcohol to prepare shell core nanobody, increase skin permeability, then mix plant essential oil with cross-linking liquid, encapsulate plant essential oil and shell core nanobody to prepare double shell core nanobody dispersion, composite plant essential oil further enhances skin permeability, and double shell core nanobody dispersion is surface modified with distearic acid acyl phosphatidylethanolamine-polyethylene glycol-N-hydroxysuccinimide to prepare plant nanofluid, and then mixed with matrix composition.

[0007] However, the above-mentioned compositions or cosmetics basically circulate on the surface of the skin and are unable to deeply inhibit tyrosinase activity, scavenge free radicals, and are unable to promote collagen and other peptide raw materials to penetrate into the skin completely or promote peptide synthesis.

[0054] The efficacy of existing anti-aging or antioxidant cosmetics varies greatly. They basically circulate on the surface of the skin and are unable to deeply inhibit tyrosinase activity, scavenge free radicals, or promote collagen and other peptide raw materials to penetrate into the skin completely or promote peptide synthesis.

[0055] A first aspect of an embodiment of the present application provides an anti-aging composition, comprising, by weight, 0.05-0.20 parts of collagen, 0.05-0.20 parts of elastin, 0.10-3.00 parts of water lily extract, 0.50-2.20 parts of mulberry leaf extract, 0.50-2.40 parts of yam extract, and 1-10 parts of β-cyclodextrin.

[0056] In some optional embodiments, the preparation method of the water lily extract is as follows:

[0057] The water lily flower and ethanol are mixed, and the supernatant is collected after extraction and centrifugation, and then subjected to rotary evaporation, dissolved in water, and freeze-dried to obtain the water lily flower extract.

[0058] Optionally, the ratio of the water lily to ethanol is 1 g: 1-20 ml, preferably 1 g: 10 ml.

[0059] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0060] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0061] In some optional embodiments, the preparation method of the mulberry leaf extract is as follows:

[0062] The mulberry leaves and ethanol are mixed, the supernatant is collected after extraction and centrifugation, and then the supernatant is subjected to rotary evaporation, dissolved in water, and then freeze-dried to obtain the mulberry leaf extract.

[0063] Optionally, the ratio of the mulberry leaves to ethanol is 1g:1-20ml, preferably 1g:10ml.

[0064] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0065] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0066] In some optional embodiments, the preparation method of the yam extract is as follows:

[0067] The yam powder and ethanol are mixed, and the supernatant is collected after extraction and centrifugation, and then subjected to rotary evaporation, dissolved in water, and freeze-dried to obtain the yam extract.

[0068] Optionally, the ratio of the yam powder to ethanol is 1g:1-20ml, preferably 1g:10ml.

[0069] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0070] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0071] It should be noted that the yam powder is specifically obtained by the following method:

[0072] The yam is dried at 60°C, crushed, and sieved (80 meshes) to obtain yam powder.

[0073] In some optional embodiments, the collagen is recombinant type III collagen. In fact, collagen is a high-grade protein whose molecules are composed of a variety of amino acids, including proline, glycine, etc. Its unique biological activity is built on the three-dimensional structure of triple superhelix. As the most abundant and widely distributed protein in the human body, collagen builds a tough support structure in the skin, bones and connective tissue, and is closely related to key processes such as maintaining the youthful state of the skin, wound healing and cell regeneration. Adult skin is mainly rich in type I collagen, while infant skin is mainly based on type III collagen, which gives the skin delicateness and elasticity. However, with age, the body's ability to synthesize type III collagen decreases, and the loss of collagen accelerates, thereby causing signs of skin aging.

[0074] In some optional embodiments, the elastin is recombinant elastin. It should be noted that elastin is the second most water-insoluble hard protein in the human body, and its structure is complex, containing more than 713 amino acid residues. These residues form two types of short peptide chains, which are arranged alternately to construct a unique elastic fiber structure, playing a key role in maintaining skin elasticity. It is mainly distributed in connective tissue, mainly giving it elastic properties, and can reach several times the original length under stretching. Elastin and collagen, elastin, glycoprotein, etc. together form the extracellular matrix (ECM) to ensure the elasticity and firmness of the skin. When elastin is missing, the muscle base tissue loses the reticular support, which leads to the appearance of skin relaxation and wrinkles. Elastin participates in the regulation of various cell behaviors, and it interacts with proteoglycans, integrins, etc., prompting various cell types (such as fibroblasts) to migrate and proliferate, triggering biological reactions. In addition, it also stimulates the synthesis of endogenous elastin, as well as the migration and differentiation of keratinocytes. However, with endogenous aging as well as external stimuli such as ultraviolet rays, elastin and the fibers it compose undergo denaturation, breakage, and loss of elasticity, which becomes one of the main signs of aging.

[0075] Moreover, recombinant elastin actually has excellent superoxide radical scavenging activity, which fundamentally slows down the occurrence of oxidative aging.

[0076] A second aspect of the present application provides a method for preparing an anti-aging composition, comprising the following steps:

[0077] By weight, 1-10 parts of cyclodextrin are dissolved in water and stirred until it becomes transparent. Then, 0.05-0.20 parts of collagen, 0.05-0.20 parts of elastin, 0.10-3.00 parts of water lily extract, 0.50-2.20 parts of mulberry leaf extract, and 0.50-2.40 parts of yam extract are added in sequence, and stirred at room temperature to obtain a liquid phase, which is then filtered and freeze-dried to obtain an anti-aging composition.

[0081] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0082] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0084] The mulberry leaves and ethanol are mixed, the supernatant is collected after extraction and centrifugation, and then the supernatant is subjected to rotary evaporation, dissolved in water, and then freeze-dried to obtain the mulberry leaf extract.

[0085] Optionally, the ratio of the mulberry leaves to ethanol is 1g:1-20ml, preferably 1g:10ml.

[0086] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0087] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0088] In some optional embodiments, the preparation method of the yam extract is as follows:

[0089] The yam powder and ethanol are mixed, and the supernatant is collected after extraction and centrifugation, and then subjected to rotary evaporation, dissolved in water, and freeze-dried to obtain the yam extract.

[0090] Optionally, the ratio of the yam powder to ethanol is 1g:1-20ml, preferably 1g:10ml.

[0091] Optionally, the specific conditions of the extraction are: ultrasound at 25-40°C for 15-30 minutes, followed by standing for 60-180 minutes.

[0092] Preferably, the specific conditions of the extraction are: ultrasonication for 15 minutes at 25°C, followed by standing for 120 minutes.

[0093] It should be noted that the yam powder is specifically obtained by the following method:

[0199] Test example:

[0200] 1. TEWL (g / m2 / h) transepidermal water loss test

[0201] Test subjects: 100 healthy subjects were selected. Inclusion criteria: age 25-40 years old, arm water content less than 40%, TEWL less than 15; the tested part has no hair, dermatitis or damage.

[0202] Test environment: constant temperature (20±2℃), constant humidity (relative humidity 50%±5%) environment.

[0203] Test method: 100 subjects were divided into 10 groups, with 10 subjects in each group. Each group of subjects used the products of Examples 1-3 and Comparative Examples 1-7, respectively. The transepidermal water loss (TEWL) of the subjects was measured before and at different times after using the products using a non-invasive measuring device TEWL (Dermalab Combo).

[0204] After using the test product, TEWL decreased significantly, indicating that the skin barrier was restored and the product had a repairing effect. The average TEWL change rate of each group of subjects after using the product was calculated, and the change rate = (average TEWL of 10 subjects in each group after using the product - average TEWL of 10 subjects in each group before using the product) ÷ average TEWL of 10 subjects in each group before using the product × 100%. The test results are shown in Table 1.

[0205] Table 1

[0206] Examples After using for 7 days After 30 days of use After 60 days of use Example 1 -16.21 -18.59 -26.42 Example 2 -15.76 -17.91 -24.37 Example 3 -17.45 -20.43 -28.54 Example 4 -16.76 -19.63 -27.21 Comparative Example 1 -10.48 -15.21 -19.11 Comparative Example 2 -6.34 -10.21 -14.34 Comparative Example 3 -5.89 -9.78 -13.22 Comparative Example 4 -5.12 -8.89 -11.29

[0207] As can be seen from Table 1, compared with before use, the TEWL (g / m2 / h) values ​​of the samples of Examples 1 to 4 were significantly reduced after 7d, 30d, and 60d of use, and the effects were sustained as the use time was extended.

[0208] The degree of reduction in TEWL (g / m2 / h) of the skin transepidermal water loss using Comparative Example 1 is higher than that in Example 1. This is mainly because when cyclodextrin is not added, the water lily extract, yam extract, and mulberry leaf extract basically circulate on the skin surface without having a sustained effect. When cyclodextrin is added to form the anti-aging compositions in Examples 1 to 3 of the present application, the cavity of cyclodextrin wraps up the water lily extract, yam extract, and mulberry leaf extract to form an embedding material, which can be slowly released to the skin surface to take effect when applied.

[0209] The degree of reduction in TEWL (g / m2 / h) transepidermal water loss using Comparative Examples 2, 3, and 4 is higher than that in Example 1, which mainly illustrates that the synergistic effect of the three ingredients of water lily extract, yam extract, and mulberry leaf extract is more conducive to avoiding skin moisture loss.

[0210] 2. Skin wrinkle test

[0211] Test subjects: Several volunteers were recruited, aged between 40 and 50, all female, without serious diseases, and with wrinkles on their faces. Each group consisted of 10 volunteers. After the volunteers washed their faces with clean water and dried them, the wrinkle status of their skin was measured and recorded as the initial wrinkle measurement value.

[0212] Test method: Volunteers were divided into groups and used the test samples prepared from the anti-aging composition containing collagen in each embodiment or each comparative example, once in the morning and evening, 2 ml each time, and the test samples were evenly applied on the face to completely cover the face, and the test samples were applied until they were completely absorbed and the skin was dry. Before using the test samples, wash the face with clean water and dry it, and then apply the test samples immediately.

[0213] After using the test sample for 90 days, measure the skin wrinkle status again, which is recorded as the 90-day wrinkle measurement value. Wash the face with clean water and wipe it dry before measurement.

[0214] Test instrument: The skin fast three-dimensional imaging system PRIMOS was used to measure the wrinkle status. The five locations of the left and right eye corners, the middle of the forehead, and the cheeks on both sides were tested. The measured value was the average of the five locations. The average of each group of test data was taken. The test data was rounded to two decimal places. The lower the measured value, the fewer the skin wrinkles. The results are shown in Table 2.

[0215] Table 2

[0216] Examples Initial wrinkle measurements Wrinkle measurement after 90 days Example 1 38.42 33.21 Example 2 36.45 30.89 Example 3 39.87 30.12 Example 4 37.89 32.34 Comparative Example 1 37.13 36.11 Comparative Example 2 39.28 37.65 Comparative Example 3 40.12 37.67 Comparative Example 4 39.22 36.98

[0217] As shown in Table 2, the 90d wrinkle measurement values ​​of Examples 1 to 4 are significantly lower than the 90d wrinkle measurement values ​​of Comparative Examples 1 to 4, and the reduction values ​​of the wrinkle measurement values ​​in Examples 1 to 4 are similar, indicating that the use of Examples 1 to 4 of the present application has obvious anti-aging functions, can significantly reduce wrinkles, and the composite system of the present application has significant antioxidant properties.

[0218] Compared with Example 1, Example 1 does not perform embedding, so that the water lily extract, yam extract, and mulberry leaf extract basically flow on the skin surface without a sustained effect. At this time, it is impossible to continuously promote collagen and elastin to enter deep into the skin, so that the anti-aging effect is not obvious.

[0219] Compared with Comparative Examples 2 to 4, Example 1 shows that the comparative example destroys the compound system of water lily extract, yam extract, and mulberry leaf extract, thereby reducing the effect of eliminating free radicals, so that the comparative example has limited effect in slowing down aging and delaying the formation of wrinkles. In practice, water lily extract contains tannins, flavonoids, alkaloids, anthraquinones, saponins, cardiac glycosides, phenols and other biologically active substances, which can scavenge free radicals on the skin surface and can also act as stabilizers and reducing agents. The phenolic compounds in the mulberry leaf extract have antioxidant and anti-aging effects and can scavenge free radicals. The yam extract The extract contains p-hydroxybenzyl alcohol, p-hydroxybenzaldehyde and allantoin, which can enhance anabolic reactions and thus enhance the ability to synthesize collagen in the skin. Therefore, through the stabilizing effect of water lily extract on anabolism, the ability of water lily extract and mulberry leaf extract and even elastin to scavenge free radicals, and the ability of yam extract to activate the body's synthesis of collagen, the three work synergistically to achieve a significant anti-aging effect. In addition, through the external supplementation of collagen and the coordination of the internal synthesis effect, the speed of collagen accumulation in the skin is greatly increased, effectively reducing the number of wrinkles and improving the anti-aging effect.
