[0079]

[0080]

[0081] Efficacy verification:

[0082] The serums prepared in Examples 1-6 and Comparative Examples 1-7 were used as test samples, and recruited subjects who met the criteria were used as test subjects. The test subjects were divided into different test groups. Each test subject first cleansed their face with the specified cleansing sample and sat quietly for 30 minutes in a laboratory at a temperature of 21±1℃ and a humidity of 50±10% RH. The baseline values ​​of various indicators of the skin around the eyes (before use) were measured. Then, the test subjects took an appropriate amount of the test sample and gently applied it to the skin around the eyes. After 30 minutes or 1 hour of application, the test values ​​of various indicators were measured (after use).

[0083] 1) Test subjects: Healthy women / men aged 25-55, with crow's feet, under-eye wrinkles (wrinkle grade ≥2, refer to "Skin Aging Atlas"), and dry and loose skin around the eyes.

[0084] 2) Test indicators and instruments

[0085] The moisture content of the stratum corneum was measured using a Corneometer CM825, with the test site being the outer corner of the eye. The higher the measured value, the higher the moisture content of the stratum corneum.

[0086] Skin elasticity R2 value and skin firmness F4 value were measured using a Cutometer dual MPA580. The test site was the outer corner of the eye. The larger the R2 value, the better the skin elasticity; the smaller the F4 value, the better the skin firmness.

[0087] Crow's feet wrinkles (level 3 smile lines) were measured using Antera 3D for image acquisition. Skin texture was reconstructed from shape through coloring, and spatial and spectral analysis was performed using 24 LEDs at 7 different wavelengths to achieve a realistic 3D skin surface reconstruction. The level 3 smile atlas is shown below. Figure 1 As shown.

[0088] 3) Test Results

[0089] 3.1 Based on the length, depth, and roughness Ra value of crow's feet (level 3 smile lines) measured before (0h) and 30min after using the test sample, the reduction rate of crow's feet length (level 3 smile lines) ((length of crow's feet before use - length of crow's feet after use) / length of crow's feet before use * 100%), the reduction rate of crow's feet depth (level 3 smile lines) ((depth of crow's feet before use - depth of crow's feet after use) / depth of crow's feet before use * 100%), and the reduction rate of crow's feet roughness Ra value (level 3 smile lines) ((Ra value of crow's feet before use - Ra value of crow's feet after use) / Ra value of crow's feet before use * 100%) were calculated for each test sample group.

[0090] The test group results for Examples 1-4 and Comparative Examples 1-5 are shown in Table 3 (the results are average values).

[0091] Table 3

[0092]

[0093]

[0094] As can be seen from the results in Table 3, after using the serums prepared in Examples 1-4 as test samples for 30 minutes, compared with before use, the length, depth, and roughness Ra value of crow's feet (level 3 smile lines) all decreased significantly. Figure 1 Examples 1 and 2 in the text are Antera 3D images of crow's feet (level 3 smile lines) of two subjects before use (T0) and 30 minutes after use (T30min) using the essence of Example 1 as the test sample. Figure 1 It is evident that crow's feet (level 3 smile lines) are significantly improved after use.

[0095] As can be seen from the comparison of the effects of Example 2 and Comparative Examples 1-4, when the serum does not contain water / 1,2-pentanediol / 1,2-hexanediol / conopeptide, acetyl glucosamine / water, butylene glycol / hydroxypropyl tetrahydropyranotriol / water, or cyclodextrin / Centella asiatica extract, the reduction rates of crow's feet length, depth, and roughness Ra value all decrease to varying degrees. This indicates that water / 1,2-pentanediol / 1,2-hexanediol / conopeptide, acetyl glucosamine / water, butylene glycol / hydroxypropyl tetrahydropyranotriol / water, and cyclodextrin / Centella asiatica extract can significantly improve crow's feet (level 3 smile lines) through their combined action, achieving a significant anti-wrinkle effect.

[0096] 3.2 Based on the skin stratum corneum moisture content, R2 value, and F4 value measured before (0h) and 1h after using the test sample, the following calculations were made for each test sample group: skin stratum corneum moisture content increase rate ((skin stratum corneum moisture content after use - skin stratum corneum moisture content before use) / skin stratum corneum moisture content before use * 100%), skin elasticity R2 value increase rate ((R2 value after use - R2 value before use) / R2 value before use * 100%), and skin firmness F4 value decrease rate ((F4 value before use - F4 value after use) / F4 value before use * 100%). The test group results for Examples 1-6 and Comparative Examples 1-7 are shown in Table 4 (the results are average values).

[0097] Table 4

[0098]

[0099]

[0100] As can be seen from the results in Table 4, after using the serums prepared in each embodiment as test samples for 1 hour, compared with before use, the skin stratum corneum moisture content increased significantly, the skin elasticity R2 value increased significantly, and the skin firmness F4 value decreased significantly.

[0101] Furthermore, a comparison of the effects of Example 2 with Comparative Examples 1-5 shows that when the serum does not contain water / 1,2-pentanediol / 1,2-hexanediol / conopeptide, acetyl glucosamine / water, butylene glycol / hydroxypropyl tetrahydropyranotriol / water, glycerin / water / thyme flower / leaf extract / Buddleja officinalis extract or cyclodextrin / Centella asiatica extract, the rate of increase in skin elasticity R2 value and the rate of decrease in skin firmness F4 value both decrease to varying degrees. A comparison of Example 2 with Comparative Examples 6-7 shows that when glycerin / water / thyme flower / leaf extract / Buddleja officinalis extract is not added and the content of butylene glycol / hydroxypropyl tetrahydropyranotriol / water is increased to 0.1 parts, or when butylene glycol / hydroxypropyl tetrahydropyranotriol / water is not added and the content of glycerin / water / thyme flower / leaf extract / Buddleja officinalis extract is increased to 0.1 parts, the rate of increase in skin elasticity R2 value and the rate of decrease in skin firmness F4 value both decrease to varying degrees. This demonstrates that the present invention, by employing a combination of water / 1,2-pentanediol / 1,2-hexanediol / conopeptide, acetyl glucosamine / water, butylene glycol / hydroxypropyltetrahydropyranotriol / water, glycerin / water / thyme flower / leaf extract / Buddleja officinalis extract, and cyclodextrin / Centella asiatica extract, achieves a synergistic effect, significantly increasing the R2 value and decreasing the F4 value, thus giving the serum a significant immediate firming effect.

[0102] A comparison of Examples 3 and 5-6 shows that when the ratio of butylene glycol / hydroxypropyltetrahydropyranotriol / water and glycerin / water / thyme flower / leaf extract / Buddleja officinalis extract is 1:1, the increase rate of skin elasticity R2 value (from 9.22% and 11.56% to 12.62%) and the decrease rate of skin firmness F4 value (from 8.76% and 9.23% to 11.94%) can be further improved, achieving better immediate firming effect.

[0103] Furthermore, the results of human trials of the serums prepared in the various embodiments and comparative examples of the present invention showed that the skin reactions of the subjects were all grade 0, and no adverse reactions occurred.

[0104] This invention has many specific applications, and the above description is only a preferred embodiment. It should be noted that the above embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this invention. For those skilled in the art, several improvements can be made without departing from the principle of this invention, and these improvements should also be considered within the scope of protection of this invention.
