Description

Technical Field

[0001] The invention belongs to the technical field of skin care product raw material formula, and specifically relates to a firming, soothing and repairing composition and a preparation method and application thereof. Background Art

[0002] As consumers' demands for skin care products become increasingly diversified, the coordinated realization of multiple functions such as firming, soothing and repairing has become an important direction for the research and development of skin care products. However, most products in the existing technology tend to focus on a single function, such as only focusing on anti-wrinkle or moisturizing, which is difficult to meet users' needs for comprehensive skin care effects. In addition, commercially available products often rely on chemically synthesized ingredients (such as retinol, acid compounds, etc.). Although the short-term effects are significant, long-term use can easily cause skin irritation, sensitivity and other problems, and are especially not suitable for people with damaged barrier or sensitive skin.

[0003] In recent years, natural plant extracts have gradually attracted attention due to their mildness and rich active ingredients. However, the application of plant extracts in the existing technology still has many limitations: first, the synergistic effect between different plant components is not well studied, which makes it difficult to maximize the efficacy of the compound composition; second, traditional extraction processes, such as high temperature and long-term decoction, are easy to destroy heat-sensitive active ingredients and reduce the biological activity of the extracts; third, the molecular weight of the key ingredients in some formulas is too large, which makes it difficult to be absorbed through the skin, affecting their actual efficacy.

[0061] 1.2 Sample addition

[0062] The experiment was divided into a test sample group, a model control group, and a blank control group. Each group had 4 replicate wells, and the addition amounts of the solutions in each group were shown in Table 3.

[0063] Table 3 Experimental grouping and sample addition

[0064]

[0065] 1.3 Determination

[0066] Leave it at room temperature for 15 min for reaction, and measure its absorbance at 420 nm with an enzyme-labeled instrument.

[0067] 1.4 Result calculation

[0068]

[0069] In the formula: A0 - the average absorbance of the blank control well;

[0070] A1 - the average absorbance of the sample well;

[0071] A2 - the average absorbance of the model control well.

[0072] 1.5 Data statistics

[0073] Use the SPSS 19.0 statistical software package for statistical analysis. If the test data is normally distributed, the independent T-test method is used for statistical analysis; if the test data is non-normally distributed, the rank sum test method is used for statistical analysis. The statistical method uses a two-tailed test, and the test level a = 0.05.

[0074] 1.6 Experimental results

[0076]

[0077]

[0078] Note: "a" indicates a significant difference compared with the model control, "aa": p < 0.01, "aaa": p < 0.001; "b" indicates a significant difference compared with test sample 2, "bb": p < 0.01, "bbb": p < 0.001.

[0079] 1.7 Result analysis

[0080] According to the data in Table 4, there were significant differences in the inhibitory rates of test samples 1 - 8 on porcine pancreatic elastase. The inhibitory rate of test sample 2 was the highest, reaching 47.12%, and there was a highly significant difference compared with the model control group (p < 0.001), indicating that its firming and anti-wrinkle effect was the best.

[0081] The inhibition rates of test samples 1 and 3 were 42.43% and 45.84% respectively, showing no significant difference from test sample 2, indicating that soluble type XXI collagen, Euglena gracilis extract, Acer rubrum extract and Nymphaea alba flower extract in the present invention exhibit good efficacy within a certain ratio range.

[0082] The inhibition rates of test samples 4 - 8 decreased significantly, indicating that the absence or excess of any one component in soluble type XXI collagen, Euglena gracilis extract, Acer rubrum extract and Nymphaea alba flower extract has a great impact on the performance of the formulation. Among them, although the inhibition rate of test sample 8 is higher than that of compositions 4 - 7, it is still significantly lower than that of compositions 1 - 3, suggesting that the balance of each component in the formulation is crucial, and the excessive presence of a single component may destroy the synergistic effect of the overall formulation.

[0091] 2.2.2 Grouping and administration

[0092] The RAW 264.7 cells cultured to the logarithmic growth phase were seeded at 1×10 5Inoculate at a density of cells per well in a 96-well plate and divide into groups: normal group, model control group, and test sample group. Repeat 6 wells in each group as duplicates. Except for the cells in the normal group, add complete medium containing LPS at a final concentration of 1 μg / mL to the cells in the other groups. After culturing for 24 h, add samples according to the grouping shown in Table 5 and culture for another 24 h:

[0093] Table 5 Stimulation and drug administration

[0094]

[0095] After culturing for 24 h, collect the cell supernatant and determine the content of IL-1β in the cell supernatant according to the operating steps of the ELISA kit.

[0096] 2.3 Data statistics

[0097] Use the SPSS 19.0 statistical software package for statistical analysis.

[0105] 2.5 Result analysis

[0106] According to the results in Table 6, it can be seen that the inhibition rates of test sample groups 1, 2, and 3 on inflammatory factors reached 83.54%, 84.54%, and 79.68% respectively. Among them, test sample group 2 had the best effect and was significantly different from the model control group (p < 0.001). This indicates that soluble type XXI collagen, Euglena gracilis extract, Acer rubrum extract, and Nymphaea alba flower extract in the present invention also show good anti-inflammatory and soothing effects within this ratio range.

[0107] 3 Repair efficacy

[0108] 3.1 Principle

[0109] Keratinocytes are important cells in the epidermal layer. The behavior of keratinocytes has an important impact on whether the skin can recover in time after being damaged. By comparing the migration changes of keratinocytes in the blank control group and the sample group, it can be evaluated whether the test sample is beneficial to the reconstruction of the barrier function in the case of damaged skin barrier.

[0114] Test sample group 1: complete medium containing 1 wt% of test solution 2;

[0115] Test sample group 2: complete medium containing 0.5 wt% of test solution 2;

[0116] Test sample group 3: complete medium containing 0.1 wt% of test solution 2.

[0117] Blank control group: complete medium.

[0118] 3.4 Cell preparation

[0119] The cryopreserved cell culture was subcultured stably twice and then inoculated into a 24-well plate, and the plate was placed in a 5 v / v% CO2 incubator and cultured overnight.

[0120] 3.5 Testing method

[0121] Remove the cell culture insert from the monolayer cells in culture, and continue to culture the cells with the medium containing the sample. Observe the area of the cells migrating to the scratched area after 24 h, and calculate the change in the area of the cells migrating to the scratched area.

[0122] 3.6 Evaluation criteria

[0123] Compared with the blank control, the scratch between cells in the test sample group decreased and there was a significant difference (P < 0.05), indicating that the test sample group has the ability to promote keratinocyte migration in this mode.

[0124] 3.7 Experimental results

[0125] Under normal culture conditions, the migration of keratinocytes is shown in Table 7.

[0126] Table 7 Keratinocyte Migration Rate

[0127]

[0128] Note: "*" indicates significant difference compared with the blank control group. "*": P < 0.05, "**": P < 0.01.

[0129] Compared with the blank control group, the migration area of keratinocytes in the complete medium containing 1 wt% of the test solution 2 increased significantly, and the migration rate was 23.557%; the migration area of keratinocytes in the complete medium containing 0.5 wt% of the test solution 2 increased significantly, and the migration rate was 13.629%; the migration rate of keratinocytes in the complete medium containing 0.1 wt% of the test solution 2 was 5.107%. As the concentration of the test solution 2 increased, the keratinocyte migration rate showed a continuous increase, indicating that the composition provided by the present invention can effectively promote skin repair and has the effect of repairing the skin barrier.
