Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, and in particular relates to a tea energy composition for improving tired skin caused by metabolic depletion and its application. Background Technology

[0002] With the fast pace of life, irregular schedules, environmental stress, and aging, skin cell metabolism gradually declines, leading to "energy-related aging," a common skin problem faced by contemporary populations. This type of aging differs from traditional wrinkle-related aging; while wrinkles are not yet prominent, insufficient cellular energy production and disrupted metabolic cycles cause the skin to lose its natural plumpness. Key symptoms include poor complexion, dull skin tone, and decreased radiance. Furthermore, the skin's self-repair ability is weakened, resulting in a "difficult-to-recover" state. Even with basic moisturizing and whitening skincare products, it's difficult to fundamentally improve the tired-looking appearance.

[0003] Currently, skincare products targeting tired skin can be mainly divided into two categories: one is surface-modifying products, which achieve an immediate brightening effect by adding pigments, pearl powders, and other ingredients, but cannot act on the inside of skin cells, the effect is short-lived and easily falls off, and cannot solve the root problem of skin metabolic exhaustion; the other is functional skincare products, which focus on improving a single target, such as adding ingredients like vitamin C and niacinamide to inhibit melanin production to brighten skin tone, or adding ingredients like hyaluronic acid and collagen to replenish skin moisture and matrix to increase plumpness, or adding single plant extracts to regulate local metabolism.

[0004] However, existing efficacy-based products have significant technical shortcomings: First, they lack specificity. Most products fail to accurately target the core needs of people experiencing "energy-related aging," focusing only on improving skin tone or plumpness, neglecting the core pain points of poor complexion and difficulty in recovery stemming from impaired cellular energy circulation. They fail to provide a systematic solution from the perspective of cellular energy metabolism. Second, they lack synergistic effects. In existing products, each ingredient acts independently, lacking a design that regulates the entire chain of "cellular energy generation-metabolism-regeneration." This prevents them from forming a synergistic effect to strengthen cellular energy circulation, resulting in limited and short-lived improvement, making it difficult to fundamentally reverse the fatigue caused by skin metabolic depletion. Third, the selection and compatibility of ingredients are not rational enough. Some products rely on chemically synthesized energy regulators, raising safety concerns. The application of natural extracts is often limited to single ingredients, failing to fully explore the synergistic potential of multiple natural ingredients in regulating cellular energy metabolism and repairing metabolic functions. In particular, there is a lack of technical solutions for combining tea extracts with specific plant extracts and active polysaccharides to construct a cellular energy circulation and regeneration system.

[0005] Therefore, developing a natural composition that can precisely target skin cell energy circulation disorders, construct a cell energy circulation regeneration system through the synergistic effect of multiple components, fundamentally improve the tired appearance caused by skin metabolic depletion, and has high safety and long-lasting effects has become an urgent technical problem to be solved in the current skin care field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tea energy composition for improving tired skin caused by metabolic depletion and its application. This composition, through the scientific compounding of four core components, precisely targets the core mechanism of energy-related aging, synergistically reversing deep-seated tired skin, dull complexion, and loss of elasticity caused by cellular energy metabolism depletion, achieving a synergistic anti-aging effect through the superposition of the four components' efficacy.

[0007] To achieve the above objectives, the technical solution adopted by the present invention includes: In a first aspect, the present invention provides a tea energy composition for improving fatigued appearance caused by skin metabolic depletion, the composition comprising the following components in parts by weight: 1-10 parts of black tea fermentation filtrate and 2.3-9 parts of energy extract; the energy extract comprising licorice extract, desert rose leaf cell extract and Euglena gracilis polysaccharide.

[0008] The key to the tea energy composition provided by this invention lies first in its scientifically formulated proportions (1-10 parts of black tea fermentation filtrate and 2.3-9 parts of energy extract). This ratio effectively synergistically combines four core components: black tea fermentation filtrate, licorice root extract, Rosa desertica leaf cell extract, and Euglena granulosum polysaccharide. The black tea fermentation filtrate, rich in prebiotics, organic acids, and fermentation secondary metabolites, optimizes the skin's microecology, strengthens the biological barrier, and exerts antioxidant effects, reducing energy consumption caused by microbial imbalance at its source. Rosa desertica leaf cell extract enhances the skin's antioxidant defense system and protects mitochondria from environmental damage; together, they achieve energy conservation and protection. Furthermore, the Euglena granulosum polysaccharide system regulates mitochondrial function, improving insulin sensitivity, activating the AMPK pathway, promoting autophagy in aging mitochondria, and efficient mitochondrial regeneration, thus achieving cellular energy regeneration. Simultaneously, the licorice root extract, with its core component glycyrrhizin A, precisely inhibits inflammatory pathways, clearing inflammatory barriers in energy transport and ensuring efficient energy use for skin repair, achieving unimpeded flow. The four elements form a closed-loop mechanism of "saving, protecting, regenerating, and unblocking," directly targeting the root cause of tired skin due to energy metabolism depletion. Through multi-dimensional synergy from microecological stabilization, oxidative defense, mitochondrial renewal to inflammation regulation, it systematically reverses deep-seated problems such as dullness and loss of elasticity caused by staying up late and stress, achieving an excellent anti-aging effect of "1+1+1+1>4".

[0009] Preferably, the mass ratio of the licorice extract, the desert rose leaf cell extract, and the Euglena spp. polysaccharide is (0.2-1):(0.1-3):(2-5).

[0010] This invention further precisely controls the optimal mass ratio of Glycyrrhiza uralensis extract, Rosa desertica leaf cell extract, and Euglena granulosus polysaccharide in the energy extract to (0.2-1):(0.1-3):(2-5), which better achieves the synergistic effect among the components and effectively solves the problem of tired appearance caused by skin metabolic exhaustion. Compared with compositions with non-optimal ratios, this specific ratio can provide basic metabolic power for the skin by leveraging the antioxidant and keratin metabolism promoting capabilities of black tea fermentation filtrate. It can also target and synergistically improve the dullness, dryness, and sagging of the skin caused by slowed metabolism by utilizing the anti-inflammatory and soothing properties of Glycyrrhiza uralensis extract, the water-locking and revitalizing effects of Rosa desertica leaf cell extract, and the energy replenishment and barrier repair effects of Euglena granulosus polysaccharide. At the same time, it avoids the risk of weakened efficacy or skin irritation caused by imbalance of component ratios.

[0011] Preferably, the composition comprises the following components in parts by weight: 3-5 parts of black tea fermentation filtrate and 4-6.7 parts of energy extract.

[0012] Preferably, the mass ratio of the extract of Glycyrrhiza uralensis, the leaf cell extract of Rosa desertica, and the polysaccharide of Euglena spp. is (0.5-0.7):(0.5-2):(3-4).

[0013] Preferably, the composition comprises the following components in parts by weight: 5 parts of black tea fermentation filtrate and 4.8 parts of energy extract; preferably, the mass ratio of the licorice extract, desert rose leaf cell extract and Euglena spp. polysaccharide is 0.5:1.3:3.

[0014] Experimental research has shown that when the four core components are combined in the above-mentioned optimal ratio, the prepared composition can maximize the ATP production in cells, solve the problem of insufficient energy caused by skin metabolic depletion, and significantly inhibit elastase activity, thereby effectively improving the signs of fatigue such as skin laxity and fine lines caused by slow metabolism.

[0015] Secondly, the present invention provides the application of the tea energy composition in the preparation of cosmetics.

[0016] Preferably, the cosmetic product includes anti-aging products, anti-wrinkle products, or ATP energy-boosting products.

[0017] Thirdly, the present invention provides an essence comprising the aforementioned tea energy composition.

[0018] Preferably, the essence further includes at least one of a moisturizer, an antioxidant, a thickener, a chelating agent, and a preservative.

[0019] Preferably, the humectant includes at least one of 1,3-propylene glycol, glyceryl polyether-26, and sodium hyaluronate; the antioxidant includes arginine; the thickener includes carbomer and methyl glucetol polyether-20; the chelating agent includes disodium EDTA; and the preservative includes at least one of butylene glycol, p-hydroxyacetophenone, and 1,2-ethylene glycol.

[0020] Preferably, the essence comprises the following components in parts by weight: 3.3-19 parts of tea energy composition, 4-6 parts of 1,3-propylene glycol, 2-4 parts of glyceryl polyether-26, 0.05-0.25 parts of carbomer, 0.01-0.1 parts of disodium EDTA, 0.01-0.1 parts of sodium hyaluronate, 0.1-1 parts of methyl glucetol polyether-20, 0.1-0.2 parts of arginine, 1-3 parts of butylene glycol, 0.1-1 parts of p-hydroxyacetophenone, and 0.1-1 parts of 1,2-ethylene glycol.

[0021] Fourthly, the present invention provides a method for preparing the aforementioned essence, comprising the following steps: S1. Mix the humectant, chelating agent and thickener with water, heat to 75-85℃, and then homogenize for 2-5 minutes to obtain mixture A; S2. After dissolving the antioxidant in water, add it to mixture A, which has been cooled to 45-55℃, and stir until homogeneous to obtain mixture B. S3. Cool mixture B to below 45°C, add preservatives, then add tea energy composition, and stir at 400-600 rpm for 3-5 minutes to obtain the essence.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The composition of this invention, through the synergistic effect of black tea fermentation filtrate and desert rose leaf cell extract, reduces energy consumption and mitochondrial damage caused by microecological imbalance and environmental stress at the source, establishing a "saving-protecting" dual-effect barrier for cells. Euglena polysaccharide, as the core driving component, activates autophagy, clears aging mitochondria, and promotes the generation of highly efficient new mitochondria, fundamentally regenerating the cellular energy factory and significantly alleviating fatigue and metabolic stagnation caused by cellular energy depletion. Glycyrrhiza uralensis extract, through its potent anti-inflammatory effect, clears inflammatory barriers in the energy transport pathway, ensuring cellular energy security. Energy is efficiently directed to the skin repair and regeneration process, improving energy utilization efficiency. The four types of active ingredients form a closed-loop mechanism of "saving-protecting-regenerating-unblocking" under specific ratios. This not only directly targets the core mechanism of energy-related aging—cellular energy metabolism exhaustion, but also works synergistically through multiple pathways such as microecological stability, antioxidant protection, mitochondrial renewal, and inflammation regulation. As a result, it achieves a remarkable anti-aging effect of "1+1+1+1>4" in improving dull skin, loss of elasticity, and deep signs of fatigue. It is especially suitable for prominent problems such as poor complexion and weak recovery caused by staying up late and stress. Attached Figure Description

Application of Comparative Examples 1-11 Comparative Examples 1-11 provide a serum in which the active ingredients are, respectively, the compositions described in Comparative Examples 1-11. The formulation of the serum is shown in Table 4 (total parts by weight: 100 parts). The preparation method of the serum is the same as that of the application examples, except for the formulation.

[0030] Table 4 shows the formulation (parts by weight) of the serums described in Comparative Examples 1-11. Example 1 This efficacy example uses the compositions described in Examples 1-7 and Comparative Examples 1-11 as test samples. The protective effect of the samples on cells is evaluated by detecting the amount of ATP produced in the cells.

[0031] (1) Experimental Principle: Mitochondria are important regulators of cellular energy and metabolism, playing a crucial role in maintaining cell growth and survival. The core function of mitochondria is to synthesize ATP through oxidative phosphorylation, which is the well-known mitochondrial bioenergetics. Mitochondria maintain oxidative phosphorylation through the membrane potential gradient generated by the electron transport chain, thereby driving ATP synthesis. This step is accomplished by the proton pump located in the inner mitochondrial membrane. The proton pump can pump protons (H+) from the matrix into the intermembrane space. The transmembrane transport of protons causes a large number of protons to accumulate in the mitochondrial intermembrane space, forming a transmembrane potential across the inner mitochondrial membrane, i.e., the mitochondrial membrane potential. When the protons return, they drive the production of ATP, the most important energy currency of living organisms. 95% of the ATP in the human body is provided by mitochondria. This test assesses the protective effect of the sample on cells by detecting the amount of ATP produced in cells.

[0032] (2) Testing instruments: Multifunctional microplate reader (Cytation 1), electronic balance (BSA-224S) (3) Test materials: Cell line: HaCaT cells; Culture medium: High-glucose DMEM medium containing 10% fetal bovine serum Test conditions: Incubation at 37℃, 5% CO2, and saturated humidity. Test reagent: ATP content assay kit (Solepro BC0300) (4) Experimental steps 1. L929 cells in logarithmic growth phase were digested into single-cell suspensions and then seeded into 6-well plates (150,000 cells per well). After cell attachment, the cells were co-incubated with the corresponding test samples for 24 hours.

[0033] 2. Collect cells into centrifuge tubes, discard the supernatant, add 1 mL of extraction buffer for every 5 million cells, sonicate to disrupt the cells, centrifuge at 10,000 rpm at 4°C for 10 min, transfer the supernatant to an EP tube, add 500 μL of chloroform, vortex thoroughly, centrifuge at 10,000 rpm at 4°C for 3 min, collect the supernatant, and place on ice for later use. Finally, add 900 μL of ATP detection solution (the reagent mixture provided in the kit) to 100 μL of sample or 100 μL of 0.625 μmol / mL standard, and measure the absorbance at 340 nm for 10 s and 3 min.

[0034] Wherein, ΔA determination or ΔA standard = OD3min - OD10s; C standard = 0.625 μmol / mL; V extraction = 1mL. All data are expressed as mean ± standard deviation. Specific test results are shown in Table 5.

[0035] Table 5 Table 5 shows that Examples 1-5, which use the preferred components and ratios of this invention, exhibit significantly higher relative intracellular ATP content than their counterparts. Specifically, Example 1 shows the highest relative ATP content at 237.4 ± 16.0%, indicating that this ratio maximizes the activation of cellular energy metabolism pathways, replenishes skin cells with energy, and effectively improves energy deficiency caused by metabolic exhaustion. In Examples 6-7, the ratios of *Glycyrrhiza uralensis* extract, *Rosa desertica* leaf cell extract, and *Euglena microphylla* polysaccharide exceed the preferred range of this invention, resulting in a decrease in relative ATP content compared to the other examples. This demonstrates that the component ratio range defined by this invention is crucial for ensuring the optimal cellular energy enhancement effect of the composition; exceeding this range disrupts the synergistic effect between components, leading to decreased efficacy.

[0036] In Comparative Examples 1-6, when one or more of the four core components—black tea fermentation filtrate, licorice root extract, desert rose leaf cell extract, and Euglena pulvinata polysaccharide—were omitted while maintaining the same total weight percentage, the relative ATP content decreased significantly compared to the examples. In Comparative Examples 8-11, when other components were used to replace the four core components of the present invention, the relative ATP content range was also significantly lower than that of the examples. These results indicate that the four core components of the present invention are not simply additive in terms of efficacy, but rather work synergistically to achieve technical effects far exceeding those of a single component or a combination of components, significantly enhancing the composition's ability to improve cellular energy metabolism.

[0037] Example 2 In this effect example, the serums described in Application Examples 1-7 and Comparative Examples 1-11 were used as test samples to test their elastase activity.

[0038] (1) Experimental principle: Collagen forms collagen fibers and reticular fibers, and elastin forms elastic fibers. These three types of fibers together constitute the connective tissue of the skin, forming a plump and elastic structure. Elastase has the ability to break down various proteins such as collagen and elastin. Changes in the structure of elastin are closely related to skin aging. The inhibitory effect of the test sample on the substrate catalyzed by elastase is detected using an enzyme-linked immunosorbent assay (ELISA) reader to determine whether the test sample has the ability to inhibit elastase.

[0039] (2) Reagents and materials: 30 U / mg elastase (pig pancreas), N-succinyl-alanine-alanine-p-nitroaniline, tris(hydroxymethyl)aminomethane, concentrated hydrochloric acid, EGCG.

[0040] (3) Instruments and equipment: analytical balance (accurate to 0.001g), ultrasonic cleaner, pipette, pipette, colorimetric tube, volumetric flask (10mL, 100mL).

[0041] (4) Solution preparation: 1. Preparation of 0.2 mol / L Tris-HCl buffer solution at pH 8.0: Solution A: Accurately weigh 4.8456 g of Tris particles, add 100 mL of deionized water, stir and mix well to dissolve to obtain a 0.4 mol / L Tris solution; Solution B: Dilute 3.34 mL of concentrated hydrochloric acid with 96.66 mL of deionized water to obtain a 0.4 mol / L HCl solution; Mix 100 mL of solution A and 44.76 mL of solution B, adjust the pH to 8.0, and add deionized water to bring the volume to 200 mL.

[0042] 2. Elastase solution: Prepared with pH 8.0 Tris-HCl buffer. Take 0.033g of elastase and add it to 10mL of pH 8.0 Tris-HCl buffer to prepare a 100U / mL elastase solution. Prepare immediately before use.

[0043] 3. Substrate solution: Weigh 1.8057 mg of N-succinyl-alanine-alanine-alanine-p-nitroaniline and dissolve it in 10 mL of pH 8.0 Tris-HCl buffer.

[0044] 4. Positive control EGCG solution: Weigh 0.001g of EGCG powder, dissolve it in 1mL of pH8.0 Tris-HCl buffer to prepare a 1.0mg / mL solution, and then dilute it with buffer to prepare solutions of 0.5, 0.1, 0.01, 0.005, 0.003, 0.002, and 0.001mg / mL.

[0045] (5) Prepare the test solution: Table 6 Add each solution to a 96-well plate in the order shown in Table 6, incubate at room temperature for 60 min, detect absorbance at 410 nm using an ELISA reader, record and save the data, and calculate the elastase inhibition rate (%) according to formula (2).

[0046] Elastase inhibition rate (%) = [1 - (OD)] A -OD B ) / (OD C -OD D )]×100%——Formula (2) In the above formula, OD AThe absorbance values ​​are for the sample group (containing enzyme and substrate). OD B The absorbance value is for the control group (containing enzyme but not substrate); OD C The absorbance value is for the blank group (containing enzyme and substrate but no sample); OD D The absorbance value is for the blank control group (containing enzyme but no substrate and no sample).

[0047] (6) Precision: The absolute difference between two independent measurements obtained under repeatability conditions shall not exceed 10% of the arithmetic mean. Specific test results are shown in Table 7.

[0048] Table 7 Table 7 shows that the serums prepared from the compositions described in Examples 1-7 can effectively inhibit elastase activity, thereby effectively reducing the degradation of elastic fibers and improving problems such as loss of elasticity and dullness of the skin caused by metabolic exhaustion. In particular, the serum prepared from the composition of Example 1 has the best elastase inhibition ability.

[0049] When any one or more of the following components were missing in Comparative Examples 1-6—black tea fermentation filtrate, licorice root extract, desert rose leaf cell extract, and Euglena spp. polysaccharide—the elastase inhibition rate of the prepared essences was significantly lower than that of the Examples. This indicates that all four core components are essential for their anti-aging effects, and the absence of any one or two of them leads to a significant decrease in the elastase inhibition capacity of the composition. Furthermore, there is a significant synergistic effect among the four components, rather than a simple additive effect. In Comparative Examples 8-11, samples that replaced the four core components of the present invention with other components also showed significantly lower elastase inhibition rates than those of the Examples.

[0050] The above results fully demonstrate that the tea energy composition of the present invention, composed of black tea fermentation filtrate, licorice extract, desert rose leaf cell extract and Euglena polysaccharide, can effectively inhibit elastase activity under the preferred ratio and has good anti-aging effects; the four core components are indispensable and synergistic, thereby effectively improving the fatigue caused by skin metabolic depletion.

[0051] Finally, it should be noted that the above embodiments are used to illustrate the technical solutions of the present invention and not to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
