As can be seen from the data in table 5, the skin elasticity effect: example 1 is superior to comparative examples 1-3 and 4-6 and 7-8, thus demonstrating that the microemulsion-efficacy-emulsifier-containing eye cream composition of the invention can cooperate with each component in skin conditioner to synergistically increase the production of collagen, can remarkably reduce fish tail, improve skin elasticity, tighten skin, make skin smoother and smoother, increase shrinkage performance, promote wrinkles of upper eyelid, and reduce fish tail on the eye side. Wherein the content of the functional ingredient of examples 1-3 was increased, the skin elasticity effect was also increased, but when one or both of the functional ingredients were used, the effect was not as good as the present application even though the total amount was the same; the functional components are the same, but the effect is not obvious when the microemulsion functional emulsifier is not used. Fig. 1 is a graph showing the effect of lifting the upper eyelid of the eye of a subject before and after 8 weeks of use of the eye cream obtained in example 1, and it can be seen from the graph that the eye cream has the effects of obviously lifting the upper eyelid, improving eyelid sagging and wrinkling, reshaping the outline of the eye, and obviously improving the elasticity of facial skin for aged and obvious skin.
4. Evaluation of pouch removal Effect
The eye-bag removing effect test was performed on the eye creams provided in examples 1 to 3 and the eye creams provided in comparative examples 1 to 8, as follows: volunteer subjects with long-term eye bag problems were selected for 110, age 35-60, randomized into 11 groups of 10 persons each, and tested the eye creams provided in examples 1-3 and comparative examples 1-8, respectively. The specific using method comprises the following steps: after the face is cleaned and skin is refreshed in the morning and evening, a proper amount of eye cream to be tested is taken and is smeared around eyes, and the eye cream is evenly smeared and massaged until being absorbed. The pouch volumes were measured after 56 days of use, respectively, before use. The eye bag volume determination was performed using a technique called fringe projection, and 3D images of the study area were acquired by a FaceScanner and processed using Optocat software (Breuckman, germany-EoTech, france).
The efficacy criteria are shown in table 6 below:
TABLE 6
The specific test results are shown in table 7 below:
TABLE 7
From the test data in Table 7, it is found that the significant rate of the eye pouch problem of the subject's eyes was 60% or more and the inefficiency was 0% after 56 days using the eye creams provided in examples 1 to 3 of the present invention. Therefore, the eye cream composition containing the microemulsion efficacy emulsifying agent for improving the eye outline can be matched with each component in the skin conditioning agent, the synergy is achieved, the dermis layer structure is enhanced, the contraction performance is enhanced, the wrinkles of the upper eyelid are improved, the fishtail lines on the eye side can be lightened, the upper eyelid is pulled up, the eyelid sagging wrinkles are improved, the efficacy permeability of the eye cream is improved by adding the microemulsion efficacy emulsifying agent, so that the eye skin is nourished and moistened for a long time and the eye outline is remodeled.
5. Human trial evaluation experiment
The experimental method comprises the following steps: eye creams prepared in examples 1, 2 and 3 were selected as experimental samples and tested and evaluated by volunteers.
30 volunteers aged 30-50 years were selected and randomly divided into 3 groups of 10 persons each. The eye creams prepared in examples 1, 2 and 3 were used by 3 groups of volunteers, respectively. The using method comprises the following steps: after the face is cleaned, the face-cleaning cream is used once in the morning and evening around eyes every day, massage absorption is carried out, and sensory evaluation is carried out according to use feelings: each group of volunteers scored by sense, and the average value of each group of scores was taken (5 points full score, 3 points and above were greasy and moist). The results obtained for each group are shown in table 8:
table 8 test results
As can be seen from Table 8, the eye creams obtained in examples 1-3 of the present invention can maintain the moisturization of the high oil formulation while reducing the greasy feel.
