Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a plant A alcohol wrinkle-removing and firming composition suitable for sensitive skin and an application thereof. Background Art

[0002] Skin is the largest and most superficial organ of the human body and undergoes a complex and cumulative aging process throughout life. Of the ultraviolet (UV) radiation from the sun, UVA (long wave 320-400nm) and UVB (medium wave 280-320nm) are harmful to our skin and can cause problems such as pigmentation, premature aging, edema, erythema, hyperplasia, etc. One of the hallmarks of photoaging is the aggregation of dystrophic elastin, which causes an imbalance in the extracellular matrix.

[0003] Elastin is a protein present in several connective tissues and has unique physiological elasticity. Elastin is synthesized by fibroblasts and keratinocytes to provide support for blood vessels, lungs and skin. Reduced elastin synthesis and functional damage lead to loss of elasticity, resulting in sagging skin, prone to wrinkles and fat masses. Microfibrils can serve as a "scaffold" for the aggregation of tropoelastin (a soluble elastin precursor) and play an important supporting role. They are composed of components such as fibrillins, fibrobulins, microfibril-associated glycoproteins (MAGPs) and proteoglycans. After elastin is synthesized and released from cells, it aligns the cross-linked domains of microfibrils, aggregates and precipitates on this "scaffold", regulates the maturation of elastin, and microfibrils profoundly affect the biological properties of elastin. However, increased expression of matrix metalloproteinase 1 (MMP-1) reduces the synthesis of elastin and microfibrils, which is a characteristic detection indicator of photoaged skin.

[0004] The prior art provides a lot of anti-aging active substances, but most of the anti-aging active substances provided by the prior art are mainly based on exogenous collagen supplementation, and the research on endogenous anti-photoaging is not comprehensive and the effect is not ideal. Furthermore, after UVB irradiates the skin, the framework of its skin fibers is one of the structures most seriously affected by it. Its degradation leads to the gradual loss of tissue support, thereby affecting the appearance. There is a lack of a composition that effectively exerts its good biological functions, such as improving the accumulation of abnormal elastin in the extracellular space, structural degradation of elastic fibers, wrong elastic fiber orientation, and protection of the dermis. In addition, most of the anti-aging compositions provided by the prior art fail to balance high efficiency and mildness, and still have irritation problems. They are not suitable for people with sensitive skin, which limits the scope of product use. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a plant A alcohol anti-wrinkle and firming composition suitable for sensitive skin, which can effectively resist photoaging, thereby achieving excellent wrinkle removal and skin firming effects, and also has certain oil control and skin brightening effects and its application.

[0121] Effect Example 1

[0122] The effect examples of the present invention explore the effects of the anti-wrinkle and firming compositions prepared in Examples 1-15 and Comparative Examples 1-8, and the anti-photoaging liposomes on the expression of metalloproteinase MMP-1 in fibroblasts induced by UVB, as well as the effect on the expression of elastin.

[0123] 1. Effects on the expression of metalloproteinase MMP-1 in fibroblasts induced by UVB

[0124] UVB irradiation accelerates the skin aging process by enhancing the expression of various matrix metalloproteinases (MPPs), such as MMP-1, inducing the degradation of extracellular matrix proteins, and downregulating the expression of skin fibroblasts. This part of the test includes the following steps:

[0125] (1) Experimental materials: phosphate buffered saline (PBS), Solebol, Shanghai; dimethyl sulfoxide (DMSO), Damao, Tianjin; high glucose medium 1×DMEM, Gibco; fetal bovine serum (FBS), Gibco; hyaluronidase and hyaluronic acid, Solebol; human skin fibroblasts (HSF) were purchased from the Kunming Cell Bank of the Chinese Academy of Sciences.

[0126] (2) Experimental method: Take a bottle of cells in good exponential growth phase, add 0.25% trypsin digestion solution, digest to make the adherent cells fall off, and count 1-4×10 5 The cells were plated at 4% 40 μg / mL and prepared into a cell suspension, which was then inoculated into a 96-well plate. The complete medium in the well was aspirated, PBS was added, and the well was exposed to UVB light for 15 min (irradiation intensity: 80-90 μW / cm 2 , irradiation dose: 80mJ / cm 2); the blank control group did not need irradiation. After 15 minutes of irradiation, the PBS solution was aspirated. Experimental group: add sample solution and set the sample concentration to 10μM (the sample concentration here is based on the weight of the anti-wrinkle and firming composition); UVB group: add PBS, blank control group: add PBS, and all three groups were cultured for 24 hours. Take the cell lysate and extract RNA, and set 3 parallel wells for each group. Use TRIzol method to extract total cell RNA, determine the purity and concentration of RNA, and take 1μg for reverse transcription. Use SYBR Green I fluorescent chimeric dye method to perform PCR detection on cDNA, and use 2 -ΔΔCt The relative mRNA expression was calculated by the method of normalizing the data of the blank group, and calculating mRNA (%) = Σ (mRNA expression of the sample group / average mRNA expression of the blank group) / 3*100%; the results are shown in Table 3.

[0127] 2. Impact on elastin expression test

[0128] Elastin in human skin is a protein that allows many tissues in the body to maintain their original shape after stretching and contracting, and allows the skin to return to its original shape after being squeezed. As we age, the elastin fibers in the skin will gradually break and be lost, causing wrinkles and loss of elasticity. Compared with human skin, zebrafish skin is highly similar to human skin in structure, except that the epidermis is differentiated epidermal cells and mucus layer instead of stratum corneum. The elastin gene is highly conserved. Elastin in the human body is synthesized by the Eln gene, and the corresponding gene of this gene in zebrafish is Elna. By testing whether the sample promotes the expression of the Elna gene in zebrafish, it can be judged whether the sample promotes the regeneration of elastin, helps the skin anti-wrinkle, and achieves the effect of skin firming. Many domestic and foreign cosmetics achieve skin anti-wrinkle and firming effects by promoting the regeneration of elastin. This part of the test includes the following steps:

[0129] (1) Use wild-type AB strain zebrafish (Daniorerio) from a reliable source (such as the China National Zebrafish Resource Center) for spawning tests. Parent fish should have good reproductive ability, and the best age is 6 to 12 months. Cross-crossing should be used as much as possible to maintain genetic diversity. A new batch of pure strain broodstock should be replaced after 5 generations. Brood fish should not have obvious visible signs of infection and disease, and should not have undergone drug treatment within 2 months. Before the breeding and spawning test, the broodstock should be domesticated for more than 14 days after being introduced into the laboratory. Test solution preparation: Use fish embryo culture medium to directly dissolve the test substance to prepare a sample solution. The concentration in the solution should not exceed 0.1% (the test concentration of the test substance must ensure a 10% mortality rate for zebrafish embryos, and the test concentration of the test substance is based on the weight of the wrinkle-removing and firming composition).

[0130] (2) Test grouping: Zebrafish were randomly selected and evenly distributed into well plates, with 12 zebrafish in each well. The zebrafish were irradiated with 312nm UVB (accumulated irradiation to 0.3J / cm 2 ) irradiated zebrafish, with 2.5mL of fish embryo culture solution added as UVB group, 2.5mL of fish embryo culture solution containing 0.8g / L acetyl hexapeptide-8 added as positive control, 2.5mL of sample solution with a concentration of 5g / L (the sample concentration here is based on the weight of the anti-wrinkle and firming composition) added as sample group, and no UVB treatment as blank control. Six parallels per group. Place in a 28℃±1℃ incubator and culture for 24h±1h. Collect 12 zebrafish in each well into a 1.5mL tube, remove the solution, add 0.5mL of RNAlater solution, and store frozen.

[0131] (3) RNA extraction: During the test, remove the RNAlater solution and rinse with PBS solution three times. Place in an ice bath, remove the PBS solution, and add 500μL TRIzol reagent. Homogenize the embryos with a pellet pestle and place in an ice bath for 10 minutes. Add 100μL chloroform, vortex for 1 minute, and place in an ice bath for 5 minutes. Centrifuge the sample for 20 minutes, transfer the upper layer solution to a 1.5mL centrifuge tube, add 250μL isopropanol, vortex for 1 minute, place in an ice bath for 10 minutes, and centrifuge the sample for 20 minutes. Remove all supernatant, add 500μL ethanol, vortex for 1 minute, centrifuge the sample for 5 minutes, and place in an ice bath for 10 minutes. Repeat this step three times. Remove the ethanol, centrifuge the sample for 5 minutes, and open the lid in a fume hood to air-dry the sample for 10 minutes. Add 10μL DNase / RNase-free ultrapure distilled water and heat at 55℃ for 15 minutes.

[0132] (4) cDNA synthesis: Dilute the RNA sample to 1000 ng / 7 μL with DNase / RNase-free ultrapure distilled water. Synthesize RNA into cDNA using PrimeScript RT Kit containing gDNA Eraser (Takara; Cat no. RR047A) and store frozen.

[0133] (5) Perform real-time RT-PCR: Prepare primer mix and real-time PCR master mix for each primer. Dilute the cDNA sample 10-fold with ultrapure distilled water without DNase / RNase. Add 9 μL of PCR master mix and 1 μL of diluted cDNA sample to each well of a 96-well PCR plate. Seal the 96-well PCR plate with optical film, centrifuge the plate for 5 minutes, and perform real-time PCR amplification.

[0134] (6) Data and result calculation: Real-time PCR data were collected. Ct was used as the amplification result, and the amplification amount of β-actin gene was used as the housekeeping gene.-ΔΔCt The relative expression of the elastin gene (Elna) was calculated as the test result. The data of the blank group were normalized, and mRNA (%) was calculated as follows: Σ(mRNA expression of the sample group / average mRNA expression of the blank group) / 3*100%; the results are shown in Table 3;

[0137] Note: Compared with the blank control group, the significance is indicated by #, and P value < 0.05 is indicated by #. Compared with the UVB group, the significance is indicated by *, and P value < 0.05 is indicated by *, P value < 0.01 is indicated by **, and P value > 0.05 is indicated by ns.

[0138] As can be seen from Table 3, the product obtained by the technical solution of the present invention has an inhibitory effect on the overexpression of MMP-1 induced by UVB, and can also inhibit the reduction of elastin induced by UVB, and the inhibitory effect is significant. However, when any one of Pseudostellariae Cyclotide B, Rhizoma Alpiniae Extract, Herba Lycopodiellae Extract, and Phytol is missing, the inhibitory effect of MMP-1 and elastin reduction of Comparative Examples 1-4 is significantly reduced, and when other functionally similar combinations are replaced, the effects obtained by Comparative Examples 5-8 are far less than the effects obtained by the technical solution of the present invention.

[0139] Effect Example 2

[0140] The effect examples of the present invention explore the long-lasting antioxidant capacity of the wrinkle-removing and firming compositions prepared in Examples 1-11 and Comparative Examples 1-8, and the liposomes containing anti-photoaging prepared in Examples 12-15. The antioxidant effect is to fight free radicals and inhibit free radical oxidation reactions. Free radicals slow down the metabolic rate of cells inside the skin, reduce the skin's ability to store moisture, and fail to lock in moisture, which in turn causes dry skin, damaged barriers, and decreased elasticity, leading to skin aging. DPPH (1,1-diphenyl-2-trinitrophenylhydrazine) is a stable free radical, and its alcohol solution is purple. The stronger the sample's inhibition rate of DPPH, the lighter the color of the mixed solution, and the stronger the antioxidant property, which can be used as one of the indicators for antioxidant testing. The experiment includes the following steps:

[0141] (1) Solution preparation: 0.2 mM DPPH solution: Dissolve 0.001972 g DPPH in anhydrous ethanol solution, add dimethyl sulfoxide to make up to 25 mL, measure the absorbance at 517 nm and record the absorbance value between 200-800. Sample solution: Dilute the sample solution to 50% solution with dimethyl sulfoxide solution for later use.

[0142] (2) Test steps: Prepare solutions in tubes A, B, and C as follows, incubate at room temperature in the dark, add the same volume of DPPH solution every 3 h, measure the absorbance at 517 nm at different test stages and record the absorbance values, and repeat 3 times for each sample.

[0143] Tube A: 2 mL sample + 2 mL DPPH (0.2 mM) solution;

[0144] Tube B: 2 mL DPPH test solution + 2 mL PBS;

[0145] Tube C: 2mL PBS + 2mL sample;

[0146] Zero adjustment: dimethyl sulfoxide solution.

[0147] (3) Calculation method:

[0148] DPPH free radical scavenging rate: 1-(AC) / B×100%

[0149] Where:

[0150] A—absorbance value of the sample tube, i.e., absorbance value of the solution after the sample reacts with DPPH;

[0151] B—DPPH background absorbance value;

[0152] C—Sample background absorbance

[0153] The results are shown in Table 4.

[0154] Table 4

[0155]

[0156]

[0157] As can be seen from Table 4, the product obtained by the technical solution of the present invention has an inhibitory effect on DPPH. The scavenging rates of DPPH at the 1h test point of Examples 1-15 provided by the present invention are all higher than 80%. However, when any one of Pseudostellariae Cyclotide B, Rhizoma Alpiniae Extract, Herba Lycopodiellae Extract, and Phytol is missing, the scavenging effect of DPPH obtained in Comparative Examples 1-4 is significantly reduced, and when other functionally similar combinations are replaced, the effects obtained in Comparative Examples 5-8 are also far less than the effects obtained by the technical solution of the present invention. Further, it can be seen from Examples 1 and 12-15 that with repeated addition of DPPH solution, the wrinkle-removing and firming composition in Example 1 shows antioxidant fatigue at 3h and 6h, and the scavenging rate of DPPH is not as good as that of the anti-photoaging liposomes formed by encapsulating the wrinkle-removing and firming composition in Examples 12-15, and when the mass ratio of the core layer and the shell layer of the anti-photoaging liposomes is not within the preferred range, the long-term antioxidant capacity of the liposomes will decrease.

[0158] Effect Example 3

[0159] The effect example of the present invention explores the human efficacy of the cream prepared by application examples 1-13, comparative application examples 1-8 and blank application examples, comprising the following steps:

[0160] According to the "Technical Specifications for Safety of Cosmetics" (2015), 176 volunteers aged 45-60 with sensitive skin (lactic acid stinging score>3) were selected and randomly divided into 22 groups, 8 people in each group. The volunteers must have at least obvious fine lines under the eyes or crow's feet, and nasolabial folds are preferred. Under normal circumstances, the volunteers continued to use the product on their entire face for 28 days, and the anti-aging effects of application examples 1-13, comparative application examples 1-8 and blank application examples were evaluated. The specific steps are as follows:

[0161] After cleansing and moisturizing the face every morning and evening, volunteers took an appropriate amount of cream and applied it to the face, massaged it for absorption, and used it on the whole face once in the morning and evening, and returned on days 0, 7, 14, and 28. On the day of the volunteer's visit, the test area washed the face with water without applying any product, and sat quietly in an air-conditioned room with a temperature of 21±1℃ and a humidity of 50±10% for 20 minutes. Instruments were used to quantify and photograph the improvement of facial aging indicators, including Cutometer 2mm MPA 580 to measure skin firmness value (R0) and skin plastic elasticity value (R2), which showed significant improvement before and after use, and the sample was judged to have elasticity and firming effect; Visia7 to measure fine lines under the eyes, which showed significant improvement before and after use, and the sample was judged to have firming effect; Primos and Visia 7 to measure crow's feet, which showed significant improvement before and after use, and the sample was judged to have anti-wrinkle effect on crow's feet; Primos to measure nasolabial folds, which showed significant improvement before and after use, and the sample was judged to have anti-wrinkle effect on nasolabial folds; Skin-Colorimeter CL400 and Visia 7 (IPP) to measure skin brightness, which showed significant improvement before and after use, and the sample was judged to have improvement effect on skin brightness; Sebumeter SM 815 to measure skin oil content, which showed significant improvement before and after use, and the sample was judged to have oil control effect;

[0162] Improvement rate before and after use = (X mean before use - X mean after use) / X mean before use × 100%;

[0163] The results are shown in Table 5:

[0164] Table 5

[0165]

[0166]

[0167] Note: When the t-test method is used for statistical analysis, the significance is indicated by * compared with the control group, P-value < 0.05 is indicated by *, and P-value > 0.05 is indicated by ns.

[0168] It can be seen from Table 5 that the product provided by the technical solution of the present invention can significantly improve the firmness, plasticity and elasticity of facial skin, and significantly improve nasolabial folds and crow's feet, and has the effects of significantly improving wrinkle removal and firming, promoting skin elasticity, and having anti-aging effects; at the same time, the product prepared by the technical solution of the present invention can also significantly improve skin color and condition, and reduce oil secretion.

[0169] It can be seen from Application Example 1 and Comparative Application Examples 1-8 that when any one of Pseudostellariae Cyclopeptide B, Tengcha Extract, Herba Lycopodiellae Extract, and Phytol is missing, or when other functionally similar combinations are used to replace them, the effects obtained are far inferior to those obtained by using the technical solution of the present invention; among them, the comparison charts of the crow's feet test results on the left face of volunteers using the cream of Application Example 1 and Comparative Application Example 1 on D0 and D28 are as follows: Figure 1 and Figure 2 As shown, from Figure 1-2 It can also be intuitively seen that the technical solution provided by the present invention can significantly reduce the wrinkle area.

[0170] Finally, it should be noted that the above embodiments are intended to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
