Description

Technical Field

[0001] This invention relates to the field of cosmetic technology, specifically to an anti-aging composition and its application. Background Technology

[0002] Every person's skin type is unique, encompassing various types such as oily, dry, combination, and sensitive. Skin aging issues also present diverse problems, including wrinkles, sagging, and age spots. Single-formula anti-aging compositions often have limited ingredients, making them unsuitable for all skin types and unable to comprehensively address these skin problems, potentially leading to poor results or adverse reactions. Furthermore, these products typically lack a comprehensive anti-aging effect because they often target only one aspect of skin aging, unlike comprehensive anti-aging products that utilize multiple synergistic ingredients to intervene in multiple stages of skin aging. In addition, single-formulas cannot meet everyone's personalized anti-aging needs, and long-term use may lead to dependence and tolerance issues. Discontinuing use may result in rebound skin conditions or reduced product effectiveness. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-aging composition with good anti-aging effects and its application.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] In a first aspect, the present invention provides an anti-aging composition comprising the following raw materials in parts by weight: 4-10 parts of tea / yeast fermentation product, 3-12 parts of white truffle extract and 1-6 parts of red algae extract.

[0006] Tea / yeast fermentation products are obtained through specific fermentation of white tea extract and yeast. They possess extremely strong antioxidant and anti-aging capabilities, effectively combating free radicals caused by external aggressors. White truffle extract contains triterpenes as secondary metabolites, thus exhibiting good in vitro antioxidant activity. Red algae extract contains sulfated polysaccharides with excellent antioxidant capacity, inhibiting free radical generation and lipid peroxidation, thereby protecting cells from oxidative damage. These three components work synergistically through multiple antioxidant mechanisms, not only leveraging their individual strengths but also complementing each other in moisturizing, hydrating, cell renewal, and repair, comprehensively enhancing the skin's antioxidant and anti-aging effects.

[0007] Preferably, the mass ratio of the tea / yeast fermentation product, white truffle extract, and red algae extract is (0.5-1):1:(0.2-0.5).

[0008] Preferably, the anti-aging composition comprises the following raw materials in parts by weight: 6 parts tea / yeast fermentation product, 10 parts white truffle extract and 4 parts red algae extract.

[0009] Preferably, the tea / yeast fermentation product is manufactured by Shandong Tiansheng Biotechnology Co., Ltd. WhiteaFuyuebai White tea fermentation products

[0010] Secondly, the present invention provides the application of the anti-aging composition of the first aspect in the preparation of cosmetics.

[0013] Preferably, the emulsifier is at least one of stearyl alcohol polyether-2, stearyl alcohol polyether-21, and cetearyl alcohol polyether-20.

[0014] Preferably, the thickener is carbomer and / or xanthan gum.

[0015] Preferably, the preservative is p-hydroxyacetophenone.

[0016] Preferably, the method for preparing the face cream includes the following steps:

[0017] S1. Heat and mix the tea / yeast fermentation product, white truffle extract and red algae extract in the specified amounts to obtain the anti-aging composition.

[0018] S2. The anti-aging composition in the specified amount is mixed evenly with glycerin, erythritol, avocado oil, meadowfoam seed oil, ergothioneine, carnosine, collagen peptide, palmitoyl tripeptide-5, acetyl hexapeptide-8, palmitoyl tetrapeptide-7, emulsifier, thickener, preservative and deionized water to obtain the face cream.

[0019] More preferably, in the cream preparation step S1, the heating temperature is 60-70°C, the mixing speed is 500-600 rpm, and the mixing time is 10-30 min.

[0060] Performance testing

[0061] 1. Antioxidant test

[0062] The antioxidant capacity of the face creams in Application Examples 1-8 and Comparative Application Examples 1-4 was verified using DPPH free radicals. The specific steps are as follows:

[0063] Take the face creams from Application Examples 1-8 and Comparative Application Examples 1-4 respectively, and add them to 95% ethanol solution to prepare a 10 g / L test solution. Take 2 mL of the test solution in a test tube, add 2 mL of 0.1 mol / L DPPH solution (prepared with 95% ethanol solution), mix well, and incubate at room temperature in the dark for 30 min. Measure the absorbance A1 at a wavelength of 517 nm. Use an equal volume of ethanol solution as a blank group and measure the absorbance A0. At the same time, use a 1.0 mg / mL VC solution (prepared with distilled water) as a positive control group. Calculate the DPPH free radical scavenging rate according to the following formula:

[0064] The data is shown in Table 3.

[0065] Table 3 shows the DPPH removal rate data of the face creams in Application Examples 1-8 and Comparative Application Examples 1-4.

[0067] 2. Skin elasticity and anti-wrinkle test

[0068] Subjects: 80 volunteers aged 18-50 years with non-hypersensitive constitutions (male-female ratio 1:4) were randomly divided into 16 groups, with 1 male and 4 females in each group.

[0069] Test samples: face creams prepared in Application Examples 1-8 and Comparative Application Examples 1-8.

[0070] Experimental procedure: The 16 test samples were prepared at a rate of 2 mL / cm³. 2 Apply the appropriate amount to the face in a single application.

[0071] (1) Skin elasticity test

[0072] Using latex gloves, the sample was evenly applied to the test area and gently patted until absorbed. It was used once daily for 28 days. Skin elasticity was measured on day 0 and day 28. After thoroughly cleansing the face with a standardized facial cleanser, the face was gently patted dry with a tissue. The skin was left to stand for 15 minutes in a room with a room temperature of 25℃±2℃ and a relative humidity of 40±2%. The results were then measured using an MPA580 multi-functional skin analyzer manufactured by Courage Khazaka. Three points were taken from each test area to measure the R2 and F2 values ​​(average values) of skin elasticity for each group of volunteers. The results are shown in Table 4.

[0073] Skin elasticity R2 value: Total elastic-plastic ratio of the rebound portion to the tensile portion. The closer the value is to 100%, the greater the elasticity of the curve; it characterizes the viscoelasticity of the skin, and the higher the value, the better the skin elasticity. Skin elasticity F2 value: The area under the envelope curve formed during the application and removal of negative pressure in all test cycles. The smaller the value, the firmer the skin.

[0074] (2) Anti-wrinkle test

[0075] The anti-wrinkle effect was measured on days 0 and 28. After thoroughly cleansing the face with a standardized facial cleanser, the face was gently patted dry with a tissue. The subjects waited 15 minutes in a room with a room temperature of 25℃±2℃ and a relative humidity of 40±2% before having their faces photographed using a VISIA facial image analyzer. The analysis area should be kept as clear as possible, avoiding reflective areas and interference from hair. The subjects' faces (including front, left, and right sides) were photographed, and the absolute scores were statistically analyzed to record the wrinkle detection data. The experimental results are shown in Table 4.

[0080] According to the results of Application Examples 1 and 4-6 in Table 3-4, when the mass ratio of tea / yeast fermentation product, white truffle extract and red algae extract in the composition is in the range of (0.5-1):1:(0.2-0.5), the antioxidant and anti-aging properties of the face cream are at a better level.

[0081] In summary, the face cream of the present invention, by adding a specific anti-aging composition, can produce a product with good antioxidant properties and firming and wrinkle reduction.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended 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.
