[0017] See also Figure 1, a cosmetic composition with nourishing and anti-aging effects, the raw materials of the composition include: kava root extract, mung bean seed extract, glyceryl glucoside, magnolia sieboldii extract, laver extract, centella asiatica extract, agave extract, cymene, lactobacillus fermentation product, royal jelly extract, xylitol and deoxyribonucleic acid; The weight ratio of raw materials and their functions are: Kava root extract 5-8%; Kava Kava Root Extract: Has relaxing and calming properties that help relieve skin inflammation and irritation; Mung bean seed extract 2-5%; Mung bean seed extract: Rich in protein and multiple vitamins, it helps nourish and repair damaged skin cells; Glyceryl glucoside 8-10%; Glyceryl Glucoside: As a humectant, it helps retain the skin's hydration and forms a protective film to prevent water loss; Magnolia sieboldii extract 1-3%; Magnolia sieboldii extract: has antioxidant and anti-inflammatory properties, used for anti-aging and soothing skin sensitivity; Laver extract 2-4%; Laver extract: contains high levels of vitamins and minerals, has a moisturizing and repairing effect on the skin, and is used for anti-wrinkle and firming of the skin; Centella asiatica extract 7-13%; Centella Asiatica Extract: Possesses healing and regenerative abilities, used as an ingredient to promote skin repair and slow down aging; Agave extract 1-2%; Agave Extract: This extract contains antioxidants that help protect against environmental damage and is used in anti-aging day creams; Cymene 5-6%; Cymene: has antibacterial properties and is used to increase the sensory experience of the product; Lactobacillus fermentation products 1-2%; Lactobacillus ferment: acts as an antioxidant and moisturizer, helping to strengthen the skin barrier function; Royal jelly extract 3-7%; Royal jelly extract: Rich in nutrients, it is used in anti-aging products to help improve skin elasticity and reduce fine lines; Xylitol 9-10%; Xylitol: As a natural sweetener and humectant, it helps maintain formula stability and provides moisturizing effects; DNA 7-9%; Deoxyribonucleic acid: Used to repair damaged DNA and slow down the aging process.

[0018] Example 1 Specifically, the preparation process of Kava root extract is as follows: S1.1, Raw material selection: Select kava roots with a diameter of 1.5 cm, a length of 40 cm, a dark brown appearance, no insect pests, and a growth period of more than three years, to ensure that the raw materials meet the quality standards for extraction; S1.2, Washing: Use clean water to wash to remove dirt and dust external pollution, and reduce the impurities that may be introduced into the extract; S1.3, reduce moisture: use a freeze dryer to perform freeze drying at -30°C for 6 hours to reduce the moisture in the raw materials, which is beneficial to improve the subsequent extraction efficiency. Low-temperature freeze drying prevents the active ingredients from being destroyed during the high-temperature drying process and ensures the efficacy and function of the extract; S1.4, crushing: use a crusher to crush the dried kava root into powder with a particle size of 2mm-3mm to increase the contact area between the solvent and the plant material, thereby improving the extraction efficiency. The particle size of 2mm-3mm is moderate. Too fine will lead to difficulty in filtering during extraction, and too coarse will affect the extraction rate; S1.5, primary alcohol extraction: 65% ethanol was selected as the extraction solvent, and ethanol and Kava root powder were mixed evenly in a ratio of 5:1. After the mixed solution was allowed to stand for 8 hours, the ethanol in the mixed solution was evaporated by heating reflux method, and finally condensed and recovered. The experiment was repeated 5-7 times to obtain a primary alcohol extraction mixture, thereby more fully extracting the effective ingredients, because it can effectively extract the required ingredients from the plant material and is easy to process later. The extraction time and number of times need to be determined according to the experimental results to ensure the maximum extraction of effective ingredients; S1.6, Filtration: Filter the mixture after alcohol extraction using an ultrasonic filter to separate the plant residue and the extract, and collect the extract with a contrast ratio of 1:3 compared with laboratory pure water. Filtration not only removes insoluble impurities, but also helps to improve the purity and quality of the final product; S1.7, Concentration: Place the extract into a vacuum concentration device, set the temperature to 45°C, set the time to 5 hours, and finally obtain the Piper methysticum root extract to reduce the volume of the extract, thereby obtaining a high-concentration extract, avoiding high-temperature and long-term treatment, and reducing thermal decomposition or volatilization loss of active ingredients.

Harvesting and pretreatment: The flowers of Magnolia sieboldii are selected as the raw materials for extraction. The flower parts are rich in whitening and antioxidant ingredients, such as phenols and magnolidine; S2.2, crushing: crush the flowers of Magnolia sieboldii into 10-20 meshes using a crusher, so that the subsequent extraction process is more complete and efficient; S2.3, extraction: select pure water as the extraction solvent, mix the crushed Magnolia sieboldii flowers with pure water in a ratio of 8:1, and heat at 35℃-37℃ for 15h-16h, or stand at 5℃-10℃ for 7-9 days for cold soaking extraction. After heating or standing, put it into a centrifuge tube, centrifuge it at a centrifugal speed of 400 rpm for 30min, age it at 5℃-10℃ for 3-5 days, and take the supernatant; S2.4, Filtration and concentration: The supernatant was concentrated in vacuum on a rotary evaporator to 1 / 10 of its original volume, thereby obtaining the Magnolia sieboldii extract. Most of the solvent was removed to leave the concentrated solution.

[0020] Specifically, the preparation process of the lactobacillus fermentation product is as follows: S3.1, raw material preparation: select soy milk and Lactobacillus plantarum as raw materials, sterilize the fresh soy milk at 98°C for 10 minutes, then concentrate it to 1 / 15 of the original volume at 90°C, cool it at room temperature and set it aside to remove impurities and bacteria that are not conducive to the growth of lactic acid bacteria; S3.2, Pretreatment stage: sterilize the fermentation tank and agitator under ultraviolet light for 2 hours, and test the accuracy of the temperature control system and pH control system at the same time. When the accuracy reaches more than 99%, start the fermentation equipment and preheat the instrument for 30 minutes; S3.3, fermentation stage: put the concentrated soy milk and Lactobacillus plantarum into a fermentation tank, adjust the fermentation temperature of the temperature control system to 35°C-38°C, adjust the fermentation pH value of the pH control system to 4.5-5.5, and control the fermentation time to 36h-48h, which is the most suitable pH range for the growth of lactic acid bacteria. Exclude oxygen to create an anaerobic environment, and promote the growth of lactic acid bacteria by filling with nitrogen or carbon dioxide; S3.4, post-processing stage: After the fermentation is completed, the fermentation liquid is extracted, sterilized, filtered and concentrated to finally obtain the lactobacillus fermentation product. The fermentation liquid that meets the hygiene standards and product requirements is packaged and stored to ensure the safety and hygiene of the product.

[0022] Specifically, in step one, the solid raw material includes mung bean seeds, which are dried, crushed and sieved to obtain mung bean seed extract to ensure its fineness and easy mixing. The liquid raw material includes royal jelly extract and kava root extract. The concentration of active ingredients is determined in advance and adjusted to a predetermined usage concentration, and the concentration range is 96%-99%.

The water phase is pre-prepared: the water phase components include dissolved glycerol glucoside solution, the water phase components are heated to 70°C, and the temperature is maintained for 8 minutes.

[0024] Specifically, the conditions for adding sensitive raw materials in step five are: when the temperature drops to 40°C-42°C, add agave extract, magnolia sieboldii extract and deoxyribonucleic acid in sequence; when the temperature drops to 30°C-35°C, add Centella asiatica extract.

[0025] Specifically, in step six, the pH value and viscosity are adjusted: in a sterile environment, the pH value of the composition is adjusted to 5.5-6.0 using kava root extract, lactobacillus fermentation product and laver extract, and finally xylitol and royal jelly extract are added to adjust the viscosity and rheological properties of the product.

[0026] Specifically, an application of a cosmetic composition with nourishing and anti-aging effects, wherein the composition prepared according to the above preparation method is used for anti-aging, balancing oil and protecting the skin barrier.

[0027] Comparative Example 1 The freeze dryer in S1.3 of Example 1 was replaced with an oven, the temperature was changed from -30°C to 80°C, the duration was changed to 1.5 h, and the other steps remained unchanged.

[0028] Comparative Example 2 The agave extract, magnolia sieboldii extract, deoxyribonucleic acid and Centella asiatica extract in step five of Example 2 are added in step four (before cooling), and the other steps remain unchanged.

[0029] The laboratory tested the activity of the kava root extracts prepared in Example 1 and Comparative Example 1, including the content of medicinal ingredients, moisture, ash and heavy metal content. The results are shown in Table 1 below:

[0030] The Kava root extract in Example 1 has high efficacy and high safety in terms of the content of active ingredients, moisture, ash and heavy metal content, while the high-temperature drying process in Comparative Example 1 shortens the drying time, but the high temperature reduces the quality and efficacy of the extract.

[0031] The laboratory tested the finished products of the compositions prepared in Example 2 and Comparative Example 2 for skin moisturizing, skin repairing, whitening, anti-inflammatory and wound healing. The test data are shown in Table 2 below:

[0032] The finished product of Example 2 shows higher effects in skin moisturizing, skin repair, whitening, anti-inflammation and wound healing than the finished product of Comparative Example 2. The sensitive ingredients are added during the cooling process, and the low temperature retains their activity, thereby improving the moisturizing, repairing, anti-inflammation and whitening functions of the prepared composition. Since the sensitive ingredients of the product in Comparative Example 2 are damaged by the high temperature during the preparation process, the preparation method of Example 2 of the present invention can better protect the activity of the sensitive ingredients, thereby making the final product perform better in multiple skin care effects.
