Experiment 2

810 female volunteers are randomly selected, the age of the volunteers is 30-40 years, the volunteers are divided into 27 groups, each group of 30 female volunteers is respectively coated on the face of the anti-aging emulsion prepared by the embodiment and the comparative example, the anti-aging emulsion is used twice a day, once in the morning and at night, 2mL is taken each time, the anti-aging emulsion is used for 28 days, the volunteers are subjected to the following detection, and the average value of the detection results of the volunteers in each group is recorded.

Detection 1

The moisture content of the stratum corneum of the volunteer before and after the anti-aging emulsion is used 28 days is detected by a Corneometer CM825 (wherein, the larger the detection value is, the higher the moisture content of the stratum corneum is), and the change rate (%) of the moisture content of the stratum corneum is calculated and recorded.

The data from the above experiments are shown in Table 1.

TABLE 1

According to the comparison of the data of examples 4-6 in table 1, the addition of the radix scrophulariae extract is beneficial to better enhancing the anti-aging effect of the anti-aging emulsion, and is beneficial to better improving the clearance rate of free radicals, so that the aging speed of the skin is slower; meanwhile, the water content of the skin can be better improved, so that the elasticity and the compactness of the skin are higher, and the generation of skin wrinkles can be better reduced; in addition, the components in the anti-aging emulsion are natural extracts, and are non-toxic and harmless, so that the skin is not easy to be allergic.

According to the comparison of the data of the example 4 and the examples 7-8 in the table 1, the epimedium extract is added, so that the absorption of effective components in the anti-aging emulsion of a human body is favorably promoted, the free radicals in the skin are favorably reduced, the aging of the skin is favorably delayed, and the anti-aging effect of the anti-aging emulsion is better; meanwhile, the skin care product is beneficial to better improving the water content of the skin, and is beneficial to better improving the elasticity and the firmness of the skin, so that wrinkles of the skin are reduced. In addition, the components in the anti-aging emulsion are all natural extracts which are non-toxic and harmless, and are not easy to damage the skin.

According to the comparison of the data of example 4 and examples 9-12 in table 1, the anti-aging effect of the anti-aging emulsion is not greatly affected by adding the dandelion extract alone, and only when the epimedium extract and the dandelion extract are synergistically matched with each other, the anti-aging effect of the anti-aging emulsion can be better improved, so that the better removal of free radicals in the skin can be facilitated, and meanwhile, the water content of the skin can be better improved, so that the elasticity and firmness of the skin are higher, and the wrinkles of the skin can be better reduced.

As can be seen from the comparison of the data in Table 1 between example 4 and examples 13-14, the addition of yohimbine hydrochloride is beneficial to better enhance the anti-aging effect of the anti-aging emulsion and better scavenging free radicals from the skin; meanwhile, the skin moisture can be supplemented better, so that the moisture content of the skin is higher, the elasticity and the compactness of the skin are improved better, and wrinkles of the skin are fewer.

According to the comparison of the data of example 4 and examples 15-18 in table 1, the control of the components of the emollient or emulsifier and the control of the dosage ratio of the components are beneficial to better and uniformly mixing the components and better exerting the synergistic effect, thereby being beneficial to better improving the clearance rate of free radicals of the skin, leading the moisture content, elasticity and firmness of the skin to be higher, and further being beneficial to better reducing skin wrinkles.

According to the comparison of the data of example 4 and examples 19-22 in table 1, the simultaneous addition of radix scrophulariae extract, herba epimedii extract, dandelion extract and yohimbine hydrochloride, the simultaneous control of the components of the emollient or emulsifier and the control of the dosage ratio of the components are beneficial to better improving the clearance rate of free radicals, so that the skin aging speed is slower, the moisture content, the elasticity and the firmness of the skin are better improved, and the skin wrinkles are less.

According to the comparison of the data of example 4 and comparative examples 1-5 in table 1, only when polygonatum odoratum extract, momordica charantia polypeptide, cranberry extract and red clover extract are synergistically combined with each other, the anti-aging effect of the anti-aging emulsion is better enhanced, and the skin is favorably cleared of free radicals, so that the moisture content, elasticity and firmness of the skin are higher, and the skin wrinkles are favorably reduced.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
