[0075] By comparing Examples 1 to 5 and the placebo example, it can be seen that the skin care lotions to which the anti-wrinkle and firming compositions of Examples 1 to 5 are added are mild and non-irritating, while the placebo example is slightly irritating, indicating that the anti-wrinkle and firming compositions are not only mild and non-irritating themselves, but also can reduce the irritation of the formula system.

[0076] Anti-wrinkle and firming effect test: 70 female volunteers aged between 35 and 55 years old with mild to moderate skin sagging and fine lines were selected and randomly divided into 5 groups of embodiment, 8 groups of comparative example and a control group, with 5 people in each group.

[0077] Experimental process: 5 groups of volunteers in the example groups used the skin care lotions prepared by the anti-wrinkle and firming compositions and lotions of Examples 1 to 5 respectively in the morning and evening every day, and 8 groups of volunteers in the comparative example groups used the skin care lotions prepared by the anti-wrinkle and firming compositions and lotions of Comparative Examples 1 to 8 respectively in the morning and evening every day, and were respectively recorded as Example 1 to 5 groups and Comparative Example 1 to 8 groups; volunteers in the control group used the same amount of placebo as the volunteers in the example group and the comparative example group in the morning and evening every day.

[0078] The experimental period is 8 weeks. Evaluation index: through the skin firmness tester (such as ) to measure the skin firmness index, and use a skin image analyzer (such as VISIA skin detector) to evaluate anti-aging indicators such as wrinkle depth and skin elasticity, and test the volunteers to compare the improvement before and after using the samples.

[0079]

[0080]

[0081] Analysis of the results of the embodiments: The average skin elasticity (R2 value) of the experimental group volunteers of the embodiments 1 to 5 groups increased by 20.86% before and after using the samples; the control group volunteers increased by 6.2% before and after using the samples. This shows that the composition of the present invention has a significant effect on improving skin elasticity. The average skin firmness of the experimental group volunteers of the embodiments 1 to 5 groups increased by 16.88% before and after using the samples, and the control group volunteers increased by 3.1% before and after using the samples. This shows that the composition has a significant effect on improving skin firmness. The average wrinkle depth of the experimental group volunteers of the embodiments 1 to 5 groups increased by 19.1% before and after using the samples, and the control group volunteers increased by 2.7% before and after using the samples. This shows that the composition has a significant effect on improving wrinkle depth.

[0082] At the same time, it was found that, on the whole, Examples 1 to 3 had obvious improvements, while Examples 4 to 5 had insignificant improvements, indicating that the effect was limited after the addition amount exceeded the amount of each component in Example 3.
