Description

A topical composition for resisting endogenous and exogenous aging
Technical Field
The invention belongs to the technical field of daily chemicals, and relates to a skin external composition capable of resisting endogenous and exogenous aging simultaneously and a preparation method thereof.
Background
For skin aging, there are various theories regarding skin aging, such as genetics, free radical theories, nonenzymatic glycosylation theories, and the like. In general, there are two main causes of skin aging, namely, intrinsic aging and extrinsic aging.
The intrinsic aging is generally determined by genetic factors and is an irreversible process of natural aging of our skin. With age, DNA in the body is gradually damaged to cause aging and damage of cells, when mitochondrial dysfunction occurs in cells, ATP supply is reduced, and when energy is lost in cell activities, problems occur in all physiological activities, such as proliferation and differentiation of skin cells, and reduction of levels of collagen, elastin and other proteins, and finally, the structure of the skin is degraded to form aged wrinkles. Exogenous aging is mainly caused by environmental factors and life style, such as ultraviolet irradiation, PM2.5, staying up all night, eating habits, psychological stress and other problems, wherein the longest is ultraviolet irradiation, the phenomenon of skin aging occurs due to the reduction of skin collagen fibers and elastic fibers caused by long-term ultraviolet irradiation, and when the skin loses elasticity and retractive force, the skin becomes more and more lax.
Because skin aging is caused by the combined action of endogenous factors and exogenous factors, it is generally necessary to pay attention to both aspects of skin care in order to delay the aging process.
For example, chinese patent CN113244156B discloses an anti-aging composition, which comprises the following components in percentage by weight: 0.01-0.07% of humus extract, 0.001-0.05% of polyphenol antioxidant, 0.01-0.8% of mussel extract, 0.05-2% of sodium hyaluronate, 0.05-2% of sodium polyglutamate and the balance of deionized water. The patent achieves the anti-aging effect through the following four aspects: (1) the generation of skin Reactive Oxygen Species (ROS) is reduced through effective shielding of ultraviolet rays and high-energy blue light; (2) the generated excessive free radicals are effectively eliminated; (3) performing anti-inflammation repair on the damaged skin; (4) the water and nutrition are supplemented in time, and the composition is reasonably designed, so that the components can fully play the self-action, the synergistic interaction effect can be generated, and the effective anti-aging effect is realized. Chinese patent CN112932988B discloses an anti-aging composition containing polydeoxyribonucleic acid, which comprises honey and polydeoxyribonucleic acid; the disclosed anti-aging composition and skin care products including the same enhance skin cell regeneration and anti-aging effects through the synergistic effect of honey and polydeoxyribonucleic acid. Chinese patent CN108392436B discloses a skin care composition for whitening skin and resisting aging, which comprises the following components in percentage by weight: 10-35% of butanediol, 0.1-5% of glucan, 0.1-50% of lotus leaf flavone, 0.1-5% of nicotinamide and the balance of distilled water. The contents of heavy metals and microorganisms are low, and the whitening cream has remarkable whitening effect, obvious anti-aging performance and capability of removing DPPH free radicals. Chinese patent CN113893203A discloses an external skin composition containing anti-aging liposome and a preparation method thereof. The skin external composition comprises the following raw material components: 0.1-15% of anti-aging efficacy liposome, 1-30% of humectant, 1-22.5% of emollient, 1-21% of emulsifier, 0.1-10% of filler, 1-12.5% of thickener, 0.1-3.5% of preservative, 0.01-1% of pH regulator, 0.01-1% of daily essence and the balance of deionized water. The anti-aging efficacy liposome comprises the following main components: hexapeptide-11, Dunaliella salina extract, Epilobium freudenrich extract, and Gynostemma pentaphyllum extract. The patent can increase the synthesis of skin collagen, enhance the activity of superoxide dismutase, clear excessive free radicals in the skin, relieve the peroxidation damage of tissues or cells, enhance the skin barrier and strengthen the skin structure to resist skin aging and relaxation by compounding the components at the same time.
Therefore, the related technologies of the current anti-aging skin care products are various, and various active ingredients are randomly matched, so that how to compound an effective composition capable of resisting endogenous and exogenous aging simultaneously is a key and focus content of research in the cosmetics industry all the time.

The epidermal cells thus formed were used for the study starting from day 14 of culture. The anti-aging active substance in example 1 was co-cultured with human keratinocytes at various concentrations (0.5%, 1%, 2.5% of the anti-aging active substance by MASs of the culture system, respectively) for 24h, and then mitochondria were isolated to determine the activity of malate-aspartate shuttle (MAS). Specifically, 50. mu.l of the mitochondrial suspension was mixed with 2ml of a test solution (300mM mannitol, 10mM potassium phosphate, 10mM Tris buffer, 10mM potassium chloride, 5mM magnesium chloride, 2mM aspartic acid, 2mM ADP, 0.14mM NADH, 3U/ml Malate Dehydrogenase (MDH), 2U/ml aspartate aminotransferase mitochondria) at pH 7.4. The oxidation of NADH was monitored at 37 ℃ for 4 minutes at a constant temperature of 340 nm. 4mM malic acid and 4mM glutamic acid (final concentration) were added to initiate the malate-aspartate shuttle activity. The dose of malate/aspartate shuttle activity was measured at 340nm for 4 minutes.
(2) Assessment of lipid peroxidation by Malondialdehyde (MDA)
After the cell suspension was treated after co-culturing the anti-aging actives of example 1 with human keratinocytes at different concentrations (0.5%, 1%, 2.5%) for 24h, MDA levels were measured using the malondialdehyde content assay kit.
And (3) testing results:
(1) malic acid/aspartic acid shuttle assay: results in young groups of cells (cells from 35 year old donors) the anti-senescence active at concentrations of 0.5%, 1%, 2.5% can increase malate/aspartate shuttle activity by 20%, 23%, 25%, respectively, as shown in figure 1; results in senescent groups of cells (cells from 62 year old donors) the anti-senescence actives increased the malate/aspartate shuttle activity by 18%, 24%, 28% at concentrations of 0.5%, 1%, 2.5%, respectively, as shown in figure 2. In conclusion, the anti-aging active substance can effectively promote the functions of mitochondria, thereby realizing the anti-aging function.
(2) Malondialdehyde (MDA) evaluation of lipid peroxidation degree: the end product of lipid peroxidation in organisms is malondialdehyde, which can cause cross-linking polymerization of life macromolecules such as protein, nucleic acid and the like, and has cytotoxicity, the content of the malondialdehyde is an important parameter reflecting the potential oxidation resistance of the organisms, can reflect the lipid peroxidation rate and strength of the organisms, and can also indirectly reflect the tissue peroxidation damage degree, and the results shown in the result in fig. 3 show that the anti-aging active substance in the example 1 has a remarkable protective effect, and the anti-physiological lipid peroxidation is 24%, 30% and 33% respectively at the concentration of 0.5%, 1.0% and 2.5%.
