Description
Technical Field
The invention belongs to the field of cosmetics, and particularly relates to a skin care product for brightening skin and repairing skin and a preparation method thereof.
Background
The stem cells are the basic cells for reproducing and restoring beautiful appearance. Therefore, the stem cell health care has obvious beautifying and skin beautifying effects: can make the relaxed and sagging skin smooth and tight, restore the skin elasticity, reduce skin wrinkles and pigmentation. Statistics shows that the beauty effect obtained by stem cell health care of a plurality of health care people is not only the skin reconstruction effect, but also the external expression of reconstruction and restoration and overall function improvement of multiple organs and systems of the body.
With the aging, fibroblasts in human skin gradually decrease, and collagen secreted by fibroblasts gradually decreases, thereby showing the phenomena of decreased skin elasticity, wrinkles, and the like. The living autologous fibroblasts have the ability to produce collagen, and particularly when the collagen is abundantly present in the skin, the effect is more obvious, and the collagen can effectively improve the elasticity of the skin and physiologically fill wrinkles and depressed scars. Pathological results indicate that the dermis is significantly thickened and can last for more than 3 years. Clinical practice proves that the stem cells are the essential cells for reproducing and restoring beautiful appearance. Therefore, the stem cell health care has obvious beautifying and skin beautifying effects: can make the relaxed and sagging skin smooth and tight, restore the skin elasticity, reduce skin wrinkles and pigmentation.
Most of whitening components of the whitening skin care products sold on the market at present are synthetic compounds, so that some side effects cannot be avoided, and the skin of a person is easily allergic.
Chinese patent application CN107823090A discloses a whitening skin care lotion containing ambergris and a preparation method thereof. The skin care liquid contains peony stem cell extract and semen Alpiniae extract.

Test example 1 irritation test
1. Test samples: skin care products for skin color lightening and skin repair prepared in examples 1 to 3 and comparative examples 1 to 4;
2. test subjects: 70 volunteers aged 18-40 years were selected and randomly divided into 7 groups of 10 individuals each, and the test samples of the present invention were applied to each group. The subject claims: the skin is healthy, has no history of skin diseases, and has no obvious color difference;
3. the test method comprises the following steps: the testee washes hands with clear water in the morning and evening, the test sample is smeared on the hands every day, other skin care products and cosmetics are not smeared, the activity range, food and the like of the testee are treated in the same way, and the specific condition of the testee is observed after 1 week.
4. And (3) test results: the hands of the testees coated with the test samples of examples 1-3 and comparative examples 1-4 have no red swelling or the like, and have no obvious change from the hands of the testees before using the test product, which shows that all the test samples in the test can not cause allergic reaction.
Test example 2 test of corrosion resistance
1. Test samples: skin color-lightening skin-care products prepared in examples 1 to 3 and comparative example 2;
2. the test method comprises the following steps: 2g of each test sample is inoculated with 10000cfu/g of mould and pseudomonas respectively, and the strain concentration is detected on 7 days, 14 days, 21 days and 28 days respectively.
Evaluation criteria:
the corrosion resistance is extremely poor: the strain concentration is more than 1000cfu/g at 28 days;
the corrosion resistance is general: when the strain is used for 28 days, the concentration of the strain is 100-1000 cfu/g;
the corrosion resistance is excellent: when the strain is used for 28 days, the concentration of the strain is 10-100 cfu/g;
3. and (3) test results: the results of the mold-related tests are shown in Table 1, and the results of the Pseudomonas tests are shown in Table 2.
TABLE 1 comparison of the corrosion protection properties of different test samples
TABLE 2 Corrosion protection Properties of different test specimens
As is clear from tables 1 and 2, the skin care products for skin color-lightening and skin-repairing prepared in examples 1 to 3 of the present invention have excellent preservative effects, and in particular, in example 3, the concentration of mold was maintained at 56cfu/g and the concentration of Pseudomonas was maintained at 44cfu/g after 28 days, and thus example 3 is the most preferable example of the present invention. However, in comparative example 2, since the sophora flower bud extract which synergistically acts as a preservative with phenoxyethanol was removed, the concentration of mold was significantly increased to 1158cfu/g, and since phenoxyethanol itself had an excellent bactericidal effect against pseudomonas, the concentration of pseudomonas was 518cfu/g, but, as a whole, the preservative performance of comparative example 2 was significantly reduced as compared with the examples.
Test example 3 whitening effect test
1 test sample: skin care products for skin color lightening and skin repair prepared in examples 1 to 3 and comparative examples 1 to 4;
2. test subjects: 140 volunteers aged 18-35 years were selected, randomly divided into 7 groups of 20 persons each, and applied with the test samples of the present invention, respectively. The volunteer requires: the skin is healthy, has no history of skin diseases, and the skin color is not obvious.
3. The test method comprises the following steps: the volunteers clean the skin of the left forearm with clear water in the morning and evening every day, then smear the tested sample on one forearm, do not smear the skin care product on the right forearm for comparison treatment, and then place the forearm in the dark to avoid the influence of illumination on the skin chromaticity. Changes in skin color of the left and right forearm were measured 1 day before application, 30, 60 and 90 days after application using a Lab colorimetric system spectrophotometer, respectively.
4. And (3) test results: the specific test results are shown in Table 3.
TABLE 3 color difference comparison of skin care products used at different sites
Remarking: compared to the results 1 day before use.
As can be seen from table 3, the color difference of the volunteers who applied the skin care products for skin lightening and skin repairing prepared in the groups of examples 1 to 3 of the present invention changed significantly after applying for 90 days, while the color difference of the control group was not significant all the time because the test samples were not applied, and particularly the color difference of the group of example 3 was very significant, and thus example 3 is the best example of the present invention. In comparative examples 1 to 4, the whitening effect was significantly reduced due to the change of some components, and particularly in comparative examples 1 to 2, the color difference was not particularly significantly changed due to the removal of the substances having the whitening effect. This also reflects laterally the synergistic interaction between the substances of the invention.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and the present invention is not limited thereto, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and equivalents can be made in the technical solutions described in the foregoing embodiments, or some technical features can be replaced.
