Description

Anti-aging composition, freeze-dried powder containing anti-aging composition and preparation method of freeze-dried powder
Technical Field
The invention relates to the technical field of cosmetics, in particular to an anti-aging composition, freeze-dried powder containing the anti-aging composition and a preparation method of the freeze-dried powder.
Background
"anti-aging" is never a stale topic. The largest organ on the surface of the human body is, by no means, the skin, which is in direct contact with the external environment, and is subjected to conditions such as: air pollution, oxidation, ultraviolet irradiation, and other harmful factors. People who love beauty will not feel worry all the time. Furthermore, with age, the skin is more or less characterised by facial ageing, such as wrinkles, decreased elasticity, pigmentation and the like. This phenomenon is contrary to the current pursuit of beauty.
Although the eight five-flower efficacy declaration appears in the market in the past rapid development stage, the anti-aging effect is still high, and the development quantity of the anti-aging effect product in the markets in China and Japan is rapidly increased according to the development trend of new products in the world, which is in line with the demand of consumers.
However, most of the anti-aging products on the market are added with concepts, and the number of products really effective is very small. At the same time, consumers are still at the level of the loss of cognition, only knowing the "alleged ingredient" and not knowing the exertion of a specific role. This has led to a very popular "fry concept" for some time, ignoring the real value of the product itself.
The majority of the products currently on the market are traditional cosmetic formulations such as: the water emulsion cream, and the products of the preparation formulation can not protect the activity of the functional raw materials in the formula, thereby greatly reducing the efficacy of the product. In particular, the development of a composition with remarkable anti-aging effect and a freeze-dried powder preparation capable of protecting the activity of functional raw materials of the product for a long time have important practical significance.

Example 5 oligopeptide cell regeneration repair assay
Experimental products: oligopeptide-1, oligopeptide-3, oligopeptide-5
The effect of oligopeptide-1, oligopeptide-3 and oligopeptide-5 on repairing and proliferating the scratched cells is measured by using a cell culture technology, and the test method comprises the following steps: firstly culturing cells, then putting a mark pen at the back of a 6-hole plate, using a ruler to draw transverse lines uniformly, and traversing through holes approximately every 0.5-1 cm. Each hole passes through at least 5 lines.
Resuspending the cells in a cell passaging step at a density of about 25000 to 30000 cells/mL and in an amount slightly greater than that required for plating. When plating, the cell suspension was added to a 6-well plate using a pipette gun while shaking the cell suspension, and 2ml of the cell suspension was added to each well. And after the plate paving is finished, putting the 6-hole plate into a cell culture box, and culturing for 24 +/-2 hours.
The gun head is perpendicular to the transverse line scratch on the back as much as possible compared with the straight ruler, and the gun head is perpendicular and cannot be inclined. The cells were washed 3 times with PBS, the scraped cells were washed off, 2ml of maintenance serum medium containing drug was added at 1 concentration per well, and 2ml of complete medium containing no drug was added to the negative control group. The cells were cultured in a 37-degree-5-vol CO2 incubator. Samples were taken at 0, 24 hours and photographed. The results are shown in FIG. 1.
As can be seen from FIG. 1, the scratches of the cells recover to different degrees from 0h to 24h, which indicates that the oligopeptides oligopeptide-1, oligopeptide-3 and oligopeptide-5 have good effects of promoting cell proliferation and repair and have good anti-aging effects.
Example 6 testing of moisturizing and anti-aging efficacy of lyophilized powder
A good anti-aging product needs to be established on the basis of a good moisturizing effect, and the moisturizing effect of the freeze-dried powders in the examples 1-3 and the comparative examples 1-8 is compared by using an in-vivo test in the embodiment.
Experimental products: EXAMPLES 1-3 AND COMPARATIVE EXAMPLES 1-8 Freeze-dried powder + physiological saline
Blank control: physiological saline
The test method comprises the following steps: 35 volunteers meeting the requirements are selected, and each volunteer is used in the morning and evening, a half-face experimental article and a half-face blank control article, and skin moisture values are tested in the Ceilala Stem cell company at the 0 th week, the 1 st week, the 2 nd week, the 3 rd week and the 4 th week, and the results are shown in a graph 2 and a table 2.
Testing an instrument: skin moisture tester (Corneometer CM825 MDD).
TABLE 2 skin moisture values
Figure BDA0002192677040000091
As can be seen from Table 1 and FIG. 2, the compositions of the present invention have scientific mixture ratio, the moisture value (mean moisture value in the fourth week of examples 1 to 3) is increased by 32.29% compared with that before use (mean moisture value before use in examples 1 to 3) at week 4, and compared with comparative examples 1 to 8, the compositions show significant difference (p < 0.05) in improving skin moisture, which indicates that the composition of the present invention has significant synergistic effect.
Example 7 Freeze-dried powder anti-aging efficacy test
The anti-wrinkle effect of the lyophilized powders of examples 1-3 and comparative examples 1-8 on skin was evaluated using the VISIA skin imaging system. This example illustrates the study of example 3 and comparative example 5
Experimental products: 3+ physiological saline solution
Comparison products: comparative example 5 lyophilized powder + physiological saline
The test method comprises the following steps: and selecting 35 volunteers meeting the requirements, using the experimental sample for half face and the blank reference sample for half face every morning and evening, and testing the skin in the Ceilera stem cell company in 4 th week, wherein the results are shown in figures 3-4.
Testing the instrument: skin test system (VISIA).
As can be seen from FIGS. 3 to 4, the freeze-dried powder of the invention has good wrinkle-removing effect, can well smooth the texture, and has an effect obviously superior to that of the freeze-dried powder of the comparative example.
The freeze-dried powder of the embodiment 3 with the preservation time of 1 year is adopted to carry out the tests of the embodiments 6 to 7, and the results are similar to those of the embodiments 6 to 7 and have no obvious difference. The freeze-dried powder still has obvious anti-aging effect after being stored for a long time.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
