Description

Anti-aging composition and product application thereof
Technical Field
The invention belongs to the technical field of polypeptide cosmetics, and particularly relates to an anti-aging composition and a product application thereof.
Background
The problem that everyone faces is that aging comes from two aspects, endogenous and exogenous. Endogenous, i.e., human metabolism in the human body with age, can lead to collagen degradation and loss, which is irreversible; exogenous substances, namely substances polluted in life are more and more, oxidized substances are more and more, and generated free radicals can break links of collagen so as to break and lose elasticity.
Polypeptides have a wide variety of biological roles, the most prominent of which is a signaling molecule in a variety of physiological processes including defense, immunity, stress, growth, homeostasis and reproduction. These aspects have been used in the dermatological and cosmetic fields to promote extracellular matrix synthesis, avoid pigmentation, treat innate immunity and inflammation. However, polypeptide actives are sought after by the market due to their remarkable and specific efficacy, without side effects, but also due to their specificity, achieving efficacy against practical complex problems is not as expected.
Although the existing polypeptide composition for resisting aging on the market focuses on exogenous and exogenous aging, the active exogenous and exogenous targets are relatively single, and no clear mechanism and data support exists for the combined synergy. The multiple polypeptide compositions of the invention can achieve the optimal anti-aging effect on the endogenous and exogenous skin by the accurate combination of multiple targets, and meet the demands of consumers.

The anti-aging compositions prepared in examples 1 to 7 and comparative examples 1 to 10 were subjected to the above test, and the results are shown in Table 3:
TABLE 3 results of human skin fibroblast proliferation effect test
From the data analysis in Table 3, it is clear that the anti-aging composition prepared in example 1 of the present invention has a significantly better type I and type III collagen content than comparative examples 1 to 5 and a significantly better effect than examples 2 and 3; meanwhile, the effects of the embodiment 2 and the embodiment 3 are obviously better than those of the comparative examples 6-10, which shows that the composition provided by the invention has a synergistic enhancement effect when being compounded, and the combination of 4 or 5 functional components has the effect of obviously promoting the secretion of the type I collagen and the type III collagen. Example 4 has better effect than example 1 and example 7, and example 7 has better effect than example 1, which shows that the galactose derivative prepared by the invention is compounded with water-soluble vitamin E, and can be used as a transdermal absorption promoter in an anti-aging composition to further enhance the secretion promotion effect of the composition on type I and type III collagen; and the pyrazinyl ethanethiol is adopted to chemically modify galactose to obtain galactose derivatives, and the galactose derivatives are compounded with other components, so that the enhancement effect is further improved. Example 5 is better than example 4 and example 6 is better than example 1, indicating that chemical modification of caffeic acid with pyridoxine hydrochloride to obtain caffeic acid derivatives can effectively promote the secretion of type I and type III collagen.
Test example 4:
human trial evaluation
Randomly extracting 140 healthy volunteers (the ages of 25-55 years old, women, skin photo-biological types are II-IV skin, and the facial skin has the problems of fine wrinkles, poor elasticity, darkness and the like), wherein each 10 persons are one group, the inner face of the tested person is used for 2 times within 1 day, 1mL each time is uniformly coated on the face, and the skin is cleaned by clear water after 10 minutes and continuously used for 4 weeks; can maintain the regularity of life and avoid solar ultraviolet irradiation during the study. Wherein skin elasticity is measured using a skin elasticity tester MPA580 from CK, germany, and using a Revisclometer RV600 probe; the wrinkles, the tightness and the fineness are all measured by a skin detector, and a Visia skin detector is specifically adopted.
The anti-aging compositions prepared in examples 1 to 7 and comparative examples 1 to 5 were subjected to the above test, and the results are shown in Table 4:
TABLE 4 results of human body test
From the data analysis in table 4, it is known that the skin striae-lightening rate, elasticity-improving rate, firmness-improving rate and fineness-improving rate of the subject are significantly better than those of comparative examples 1 to 5 and are better than those of examples 2 and 3 after the anti-aging composition prepared in example 1 is used; meanwhile, the effects of the embodiment 2 and the embodiment 3 are obviously better than those of the comparative examples 8-14, which shows that the composition provided by the invention has a synergistic enhancement effect when being compounded, and the combination of 4 or 5 functional components shows better action effects, especially in the aspects of improving skin elasticity, improving wrinkles and the like. The effect of example 4 is better than that of examples 1 and 7, and the effect of example 7 is better than that of example 1, which shows that the galactose derivative prepared by the invention is compounded with water-soluble vitamin E, and the galactose derivative is used as a transdermal absorption promoter in an anti-aging composition, so that the effect of the composition on skin can be further enhanced, the effect of improving the light lines and the elasticity is obviously improved, and the compactness and the fineness of the skin are further improved; and the pyrazinyl ethanethiol is adopted to chemically modify galactose to obtain galactose derivatives, and the galactose derivatives are compounded with other components, so that the enhancement effect is further improved. Example 5 is better than example 4 and example 6 is better than example 1, indicating that chemical modification of caffeic acid with pyridoxine hydrochloride to obtain caffeic acid derivatives, applied in anti-aging compositions, can effectively improve the skin wrinkling and elasticity effects of the composition.
The conventional technology in the above embodiments is known to those skilled in the art, and thus is not described in detail herein.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
