Skin elasticity is the ability of the skin to stretch and recover its original shape. Elastin is a type of fibrin that is present in the extracellular matrix and is critical to the elasticity of the lungs, arteries, ligaments and skin. During maturation and aging of the human body, the dissolution of elastin accelerates the development of aging diseases. When elastin is excessively lost, skin elasticity is gradually lost, and when severe, skin sags, and the appearance of aging is presented. One of the focus of research in the cosmetic field is how to keep skin well elastic.

Test 1 elastase Activity inhibition test
Elastase, which is a proteolytic enzyme with extremely high selectivity and specificity, has a catalytic hydrolysis effect on carboxyl-containing polypeptide bonds of many amino acids such as glycine, leucine, alanine, valine, etc., and can decompose elastin in connective tissue proteins. The elastase inhibitor can effectively inhibit the activity of elastase and slow down the degradation speed of elastin.
According to the reference: li Xiaojing, sun Peidong et al, inhibition of elastase by Polygonum cuspidatum extract [ J ]. Natural product research and development, 2012,24 (03): 378-380. The cosmetic compositions prepared in examples 1-3 and comparative examples 1-3 were subjected to an elastase activity inhibition test by the method described.
The specific test steps are as follows:
taking a plurality of conical flasks, sequentially adding Congo red-elastin and borate buffer solution, oscillating for 10min at constant temperature in a water bath at 37 ℃, respectively adding elastase solution and different test objects, and measuring the absorbance of each tube at 495 nm.
The inhibition rate of the test substance on the enzyme activity is calculated as follows:
inhibition (%) = (1-An/A0) ×100%;
wherein A0 is the initial absorbance value without the addition of the test substance.
FIG. 1 is a bar graph showing the inhibition of elastase by the test substances (1% aqueous solution of the cosmetic compositions prepared in examples 1 to 3 and comparative examples 1 to 3, 1mg/mL of polydatin standard as a positive control).
As can be seen from FIG. 1, the cosmetic compositions prepared in examples 1 to 3 of the present invention have good elastase inhibitory activity.

The preparation process is the same as in example 5.
Trial 2 crowd trial test
30 female volunteers 35-60 years old were summoned, and the eye-surface tightening essence prepared in example 5 was subjected to a crowd trial test. Firstly, a subject is required to be well matched with a test, and a living rule is kept during the trial of a product; all contents of the informed consent form can be read and understood and signed voluntarily; the use of skin care products was discontinued during the trial period, no further clinical trials at any other study center were taken and no cosmetic, pharmaceutical and health care products having any effect on the results were agreed to be used.
2.1 Patch test
The skin closed patch test was performed on volunteers according to the method described in the cosmetic safety Specification (2015 edition) for human skin patch test.
The test object is placed in the plaque laboratory in an amount of about 0.020g to about 0.025g. The test substance is cosmetic product original substance, and the control hole is blank (without any substance). The patch test with the test object is applied to the back or forearm of the subject by hypoallergenic tape, and is applied to the skin with palm light pressure for 24 hr. Skin reactions were observed according to the criteria of Table 1 for 30min (after disappearance of the indentations), 24h and 48h, respectively, after removal of the subject plaque tester.
TABLE 1 skin response grading Standard for skin seal Patch test
Figure SMS_1
The test results of the skin-sealing patch show that no skin reaction of more than grade 2 occurs in 30 persons after 30 minutes (after the indentation disappears), 24 hours and 48 hours. Therefore, the eye and face tightening essence prepared by the embodiment of the invention does not show potential adverse reaction to human skin.
2.2 efficacy assessment
There are various methods for measuring skin elasticity, and more commonly used in the art is the skin elasticity meter (Cutometer MPA 580) which uses suction force (vacuum) perpendicular to the skin surface as stress.
Test arrangement: after skin cleaning, a proper amount of samples are taken and rubbed on the facial skin of a volunteer, and the samples are taken once in the morning and evening. Before use, after use for 4 weeks and after use for 8 weeks, skin elasticity is measured by a skin elastometer, and the probe repeatedly measures 3 times in the same measured area during measurement, and an average value is obtained. The specific test results are shown in table 2. Wherein the output data R7 of the skin elastometer represents the ratio of the timely rebound quantity Ur of the skin without negative pressure to the maximum stretching quantity Uf of the skin with negative pressure, and represents the compaction degree of the skin, and the numerical value is as good as the closer to 1.
