[0002] Elastin plays the role of a rubber band in the skin, enabling the skin to stretch and fold. Its function is like the spring in a mattress, responsible for maintaining and supporting the elasticity of the skin. Therefore, elastin plays an important role in maintaining skin elasticity. Elastin determines the elasticity and softness of the skin, and has the effects of preventing aging and promoting regeneration on the physiological aging process of the skin caused by physical and chemical factors such as light. Many people think that the key to skin care for retaining youth is how to supplement collagen, while ignoring another important substance in fibroblasts - elastin. If skin care products contain both elastin and collagen components, it will have a very good effect on keeping the skin young, delicate, and elastic.

[0078] Experimental Example 1

[0079] Randomly select 6 hpf wild-type AB strain zebrafish in a six-well plate, 3 mL / 30 tails / well, set up a normal control group, a model control group, a positive control group, Examples 1-3, and Comparative Examples 1-6 groups. Except for the normal control group using fish culture water as the culture medium, the other groups all use fish culture water with a hydrogen peroxide concentration of 1 mM as the culture medium; the positive control group is given the positive control drug 900 U / mL catalase in water solution, and Examples 1-3 and Comparative Examples 1-6 groups are given 1 μL / mL of the corresponding samples; the following detections are carried out respectively:

[0080] The samples were processed for 6 days, with the liquid changed daily. After 6 days, the zebrafish in each experimental group were stained with a senescence β-galactosidase staining kit. After the staining was completed, 10 zebrafish were randomly selected from each experimental group, fixed with 3% methyl cellulose, observed and photographed under a stereomicroscope. The β-galactosidase staining intensity (A) in the zebrafish was quantitatively analyzed using Image pro plus software. The ability of the samples to inhibit the enhanced β-galactosidase activity induced by hydrogen peroxide was evaluated based on the statistical analysis results of this index. The statistical processing results were expressed as mean ± SE. Graphpad Prism software was used for drawing and statistical analysis. p < 0.05 indicated that the difference was statistically significant. The calculation formula for the β-galactosidase activity inhibition rate: C = (A1 - A2) / (A1 - A0) × 100%, where,

[0081] C - the β-galactosidase activity inhibition rate, %;

[0082] A1 - the average value of β-galactosidase staining intensity in the model control group (n = 10);

[0083] A2 - the average value of β-galactosidase staining intensity in the sample group (positive control drug or Examples 1 - 3 or Comparative Examples 1 - 6) (n = 10);

[0084] A0 - the average value of β-galactosidase staining intensity in the normal control group (n = 10).

[0085] Results: After culturing with the normal control group, model control group, positive control group, Examples 1 - 3 groups, and Comparative Examples 1 - 6 groups, the zebrafish had no deaths and no obvious abnormal toxicity occurred. The test results of the β-galactosidase activity in the zebrafish of each group are shown in Table 1.

[0086] Table 1: Test results of β-galactosidase activity in zebrafish of each group

[0087]

[0088] Compared with the normal control group, ### P < 0.001; compared with the model control group, *P < 0.05, **P < 0.01 among the sample groups; compared with Example 3 group, & P < 0.05, && P < 0.01.

[0089] The staining intensity of the model control group was higher than that of the normal control group, and the difference was extremely significant (P<0.001), indicating that the model was successfully established. After administration of catalase, the samples of Examples 1-3, Comparative Example 1, and Comparative Examples 3-6, the staining intensity of the model group could be reduced, and the difference was statistically significant (P<0.05) or significant (P<0.01). Among them, the effects of each example were equivalent to those of catalase and were superior to those of each comparative example.

[0090] The composition of the present invention has a good anti-aging effect with specific component compositions and specific ratios of each component.

[0091] Experimental Example 2

[0092] Eighty female subjects aged 40-55 years were randomly divided into four groups: a blank control group, a test food group 1, a test food group 2, and a test food group 3, with 20 people in each group. Among them, the test food group 1 took the drink of the composition of Example 3 of the present application, the test food group 2 took the drink of the composition of Comparative Example 2 of the present application, and the test food group 3 took the drink of the composition of Comparative Example 5 of the present application. It was taken once in the morning and once in the evening every day, 30 mL each time, and continuously taken for 30 days. Skin elasticity and moisture were tested before and after the experiment.

[0093] Among them, a skin moisture content tester (model CM825, CK Company, Germany) was used for skin moisture testing, and a skin elasticity tester (model MPA580, CK Company, Germany) was used for skin elasticity testing. The test was carried out in a stable environment with spaciousness, good ventilation, a temperature of (21±1)°C, and a humidity of 50%±5%. The skin (forehead) moisture and elasticity of the test volunteers were measured before taking the drink of the present invention (day 0) and 30 days after taking it. Skin care products were prohibited on the day of measurement. The measured part was cleaned with a clean cotton ball dipped in distilled water under a quiet state, and after drying for 15 min, 6 measurement points were selected in the middle of the forehead, and the average value was taken. The tests of the same volunteer were completed by the same measurement personnel. The experimental results are shown in Table 2.

[0094] Table 2: Skin test results

[0095]

[0096] Note: *P<0.05 for comparison before and after the test; **P<0.01 for comparison before and after the test.

[0097] The test results showed that: after 30 days of taking the test food, the skin moisture of the subjects in the three test food groups was improved, and the skin elasticity of the test food group 1 and the test food group 3 was improved. Considering the improvement results of skin moisture and skin elasticity, the improvement degree of the test food group 1 was the most significant, superior to the test food group 2 and the test food group 3. The composition of the present invention has the ideal effects of increasing skin elasticity, anti-wrinkle, moisturizing, and increasing skin moisture, and its effects are significantly superior to the samples of the comparative example group obtained by changing the formula.

[0098] According to the above experimental results, it can be seen that through the triple compound synergistic effect of fish collagen peptide and elastin peptide, pomegranate concentrated powder and cranberry concentrated powder, and lily powder and blueberry juice powder, the obtained composition has better effects in improving skin elasticity and / or improving skin moisture and / or delaying wrinkle formation under specific component compositions and specific ratios of each component.
