Technical Field
The invention relates to a skin care composition and a preparation method thereof, belonging to the technical field of skin care products.
Background
The determinant of skin aging is the destruction of collagen in the dermal layer by the internal and external environment. Collagen supports the skin like a spring, and when the skin is broken, the dermal tissue collapses, wrinkles appear, and the skin becomes loose and sags. With age, collagen begins to be lost from skin at 18-22 years of age, and nearly 40% of the collagen is lost from skin by 45-50 years of age.
Extensive research has been conducted to find a method for preventing and alleviating skin wrinkles, and the important role of collagen has been elucidated. Collagen commonly used in cosmetics is generally derived from fish skin or pig skin, and has poor skin-friendly property, so that the transdermal utilization rate is low. On the other hand, collagen is hydrolyzed by collagenase contained in the skin, and thus the original effect is lost. At present, a plurality of anti-aging cosmetics added with collagen exist in the market, but the actual using effect is not ideal and is also because of the reason. Therefore, the preparation of collagen cosmetics with remarkable anti-aging effect is a problem to be solved urgently.

The experimental population is as follows: total 36, 30 women, 6 men, age 21-59, 6 per group, composite subject volunteer enrollment criteria;
the test method comprises the following steps: the selection area is not more than 50mm2Suitable spot tester with depth of about 1mmAdding about 0.020-0.025mL of a test object into a spot tester by a closed spot test method; the plaque test device is pasted on the curved side of the forearm of a subject, the subject is removed after 24h, the skin reaction is observed after 0.5h, 24h and 48h respectively after the removal, and the result is recorded according to the skin reaction grading standard in technical Specification for cosmetic safety (2015 edition).
And (3) test results: the 36 subjects scored 0 at 3 observation time points 0.5h, 24h, 48h after removal of the patch (negative response).
2) And (3) product efficacy test:
1. type iii collagen synthesis promotion rate test:
human fibroblasts cultured in DMEM medium containing 12% FBS were seeded in 24-well plates, and after cell attachment, medium exchange was performed with DMEM medium containing 0.22% FBS and 200 μ M magnesium ascorbyl phosphate, to which samples to be tested in examples 1 to 3 and comparative examples 1 to 3, respectively, were added. After three days of culture, the culture medium supernatant was recovered, centrifuged, and the type III collagen in the resulting supernatant was measured.
The evaluation method of the ability of type III collagen in cells to biosynthesize was carried out by measuring the content of the terminal peptide (Procollagen type III-peptide: abbreviated as PIII P) of type III collagen secreted in the supernatant using the "R IA-gnost PIII P (PIII P) measurement kit". The strength of the anti-wrinkle effect of these samples was evaluated by the promotion rate of collagen type III synthesis. The calculation formula is as follows:

2. And (3) anti-aging efficacy test:
18 volunteers of 35-55 years old were selected, sex randomized. The volunteers were randomly divided into 6 groups, and the skin care compositions of examples and comparative examples were randomly used on one of the left cheek or the right cheek, and one of the left canthus and the right canthus, respectively, of each volunteer, and were used as experimental groups; the volunteers used one cheek and the canthus of the examples and comparative examples as a control group.
The volunteers were applied once a day, in the morning and evening, with a usage period of 4 weeks, and were unable to use other cosmetics during the test period. Then, the skin care composition was comparatively analyzed for wrinkle improvement and skin elasticity of volunteers using a skin elasticity tester and a facial wrinkle imager, and the results are shown in table 4:
table 4 wrinkle improvement and skin elasticity test results
Figure BDA0002528006440000121
The wrinkles were reduced in the test group and improved significantly after the application of the example samples, compared to the control group. Meanwhile, after the skin elasticity tester is used for testing the skin of each group of volunteers, the elasticity of the skin at the position where the sample is smeared in the embodiment is obviously improved compared with the control group.
The test results show that the skin care composition composed of the soluble collagen and the Chimaphila umbellate leaf extract has a synergistic interaction effect, and the Chimaphila umbellate leaf extract can inhibit the activity of collagenase, delay the decomposition of collagen and promote the synthesis of collagen. Has synergistic effect with soluble collagen, can protect soluble collagen for long-term use, and can prevent and improve skin aging.
Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
