Description

Technical Field

[0001] This invention belongs to the field of skin care ingredient formulation technology, specifically relating to a firming, soothing and repairing composition, its preparation method and application. Background Technology

[0002] As consumers' demands for skincare product efficacy become increasingly diversified, the synergistic effect of multiple benefits such as firming, soothing, and repairing has become an important direction in skincare product development. However, most products in the current 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 skincare effects. In addition, commercially available products often rely on chemically synthesized ingredients (such as retinol, acid compounds, etc.), which, although showing significant short-term effects, can easily cause skin irritation and sensitivity with long-term use, and are especially unsuitable for people with damaged skin barriers or sensitive skin.

[0003] In recent years, natural plant extracts have gradually gained attention due to their mildness and rich active ingredients. However, the application of plant extracts in existing technologies still has many limitations: First, there is insufficient research on the synergistic effects between different plant components, making it difficult to maximize the efficacy of compound compositions; second, traditional extraction processes, such as high-temperature and long-term decoction, easily destroy heat-sensitive active ingredients and reduce the bioactivity of the extracts; third, the molecular weight of key components in some formulations is too large, making it difficult to absorb through the skin and affecting their actual efficacy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a skincare composition that offers multiple benefits including firming, anti-wrinkle, soothing, and repairing, while being made with natural ingredients, scientifically formulated, and processed gently.

[0063] Table 3 Experimental grouping and sample addition

[0064]

[0065] 1.3 Determination

[0066] The reaction was placed at room temperature for 15 min, and the absorbance was determined at 420 nm by using an enzyme marker.

[0071] A2 is the average absorbance of the model control hole.

[0072] 1.5 Data statistics

[0073] SPSS19.0 statistical software package was used for statistical analysis. If the test data is normally distributed, independent T test method is used for statistical analysis; if the test data is not normally distributed, rank sum test method is used for statistical analysis. The statistical method uses two-tailed test, and the test level a = 0.05.

[0081] The inhibition rates of the test samples 1 and 3 are 42.43% and 45.84% respectively, and there is no significant difference with the test sample 2, which indicates that the soluble collagen type 21, the euglena gracilis extract, the Acer Rubrum extract and the Zantedeschia aethiopica flower extract in the present application have good efficacy performance within a certain ratio range.

[0082] The inhibition rates of the test samples 4-8 decrease significantly, which indicates that the absence or excess of any one of the soluble collagen type 21, the euglena gracilis extract, the Acer Rubrum extract and the Zantedeschia aethiopica flower extract has a great impact on the performance of the formula, and the inhibition rate of the test sample 8 is still significantly lower than that of the test samples 1-3, which indicates that the balance of each component in the formula is crucial, and the excess of a single component may destroy the synergistic effect of the whole formula.

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

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

[0117] Blank control group: complete culture medium.

[0118] 3.4 Cell preparation

[0119] After two stable passages of the cell culture from the frozen preservation, inoculate in a 24-well plate, and place the well plate in a 5v / v% CO2 incubator for overnight culture.

[0120] 3.5 Test method

[0121] Remove the cell culture insert from the cultured monolayer cells, and continue to culture the cells using the sample-containing medium. After 24h of observation, calculate the area change of the cells migrated to the scratch area.

[0122] 3.6 Evaluation basis

[0123] Compared with the blank control, the cell-to-cell scratch of the test sample group is reduced, and there is 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 Test results

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

[0126] Table 7 Keratinocyte migration rate

[0127]

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

[0129] Compared with the blank control group, the keratinocyte migration area of the complete medium containing 1wt% of the test solution 2 has a significant increase, and the migration rate is 23.557%; the keratinocyte migration area of the complete medium containing 0.5wt% of the test solution 2 has a significant increase, and the migration rate is 13.629%; the keratinocyte migration rate of the complete medium containing 0.1wt% of the test solution 2 is 5.107%, and with the increase of the concentration of the test solution 2, the keratinocyte migration rate shows a continuously increasing result, which shows that the composition provided by the application can effectively promote the repair of the skin and has the effect of repairing the skin barrier.
