Description

A skin external composition capable of simultaneously resisting aging of internal and external sources
Technical Field
The invention belongs to the technical field of daily chemicals, and relates to a skin external composition capable of simultaneously resisting internal and external aging and a preparation method thereof.
Background
For skin aging, there are various theories about skin aging, such as genetic theory, radical theory, non-enzymatic glycosylation theory, and the like. Overall, there are two main causes of skin aging, namely endogenous aging and exogenous aging.
Wherein endogenous aging is generally determined by genetic factors, and is an irreversible process of natural aging of skin. With age, in vivo DNA is gradually damaged to cause aging and damage of cells, when mitochondrial dysfunction occurs in cells, ATP supply is reduced, and when cellular activity lacks energy, problems of all physiological activities such as proliferation, differentiation, reduction of collagen, elastin and other proteins of skin cells are caused later, and finally, the skin structure is degenerated to form aged wrinkles. Exogenous aging is mainly caused by environmental factors and life style, such as ultraviolet irradiation, PM2.5, staying up night, eating habit, psychological stress and other problems, wherein the longest problem is that the ultraviolet irradiation, long-term ultraviolet irradiation causes the reduction of collagen fibers and elastic fibers of the skin to cause the aging of the skin, and when the skin loses elasticity and retractive force, the skin becomes more and more loose.
Since skin aging is caused by the combined action of endogenous and exogenous factors, it is generally necessary to pay attention to how to care skin from both aspects in order to delay the progression of aging.
Many related technologies about anti-skin aging, such as chinese patent CN113244156B, disclose an anti-aging composition comprising the following components in weight percent: 0.01 to 0.07 percent of humus extract, 0.001 to 0.05 percent of polyphenol antioxidant, 0.01 to 0.8 percent of mussel extract, 0.05 to 2 percent of sodium hyaluronate, 0.05 to 2 percent of sodium polyglutamate and the balance of deionized water. The anti-aging effect is achieved by the following four aspects: (1) The generation of skin Reactive Oxygen Species (ROS) is reduced by effectively shielding ultraviolet rays and high-energy blue light; (2) effective scavenging of the excess free radicals generated; (3) performing anti-inflammatory repair on damaged skin; (4) The composition can fully exert the functions of the components and produce synergistic effect to realize effective anti-aging effect through reasonable design. Chinese patent CN112932988B discloses an anti-aging composition containing polydeoxyribonucleic acid, comprising honey and polydeoxyribonucleic acid; the disclosed anti-aging composition and skin care product comprising 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 anti-aging, comprising the following components in weight percentage: 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 content of heavy metals and microorganisms is low, so that the whitening cream has remarkable whitening effect, has remarkable anti-aging performance and can remove DPPH free radicals. Chinese patent CN113893203a discloses a skin external composition containing anti-aging liposome and its preparation method. 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 main components of the anti-aging efficacy liposome comprise: hexapeptide-11, dunaliella salina extract, leucasian willow leaf extract, gynostemma pentaphyllum extract. The preparation method can increase the synthesis of skin collagen, enhance the activity of superoxide dismutase, remove excessive free radicals in skin, relieve peroxidation damage of tissues or cells, strengthen skin barrier, strengthen skin structure and resist skin aging relaxation by simultaneously compounding the components.
Therefore, the related technology of anti-aging skin care products is numerous, and various active ingredients are matched at will, so that how to compound the composition which is effective and can resist the internal and external aging is the key point and the hot point of the research in the cosmetic industry.

The epidermal cells thus formed were used for the study since day 14 of culture. The anti-aging active substance in example 1 was co-cultured with human keratinocytes at different concentrations (the concentration means that the anti-aging active substance accounts for the MASs concentration of the culture system, 0.5%, 1%, 2.5% were selected respectively) for 24 hours, and then mitochondria were isolated, and the activity of malate-aspartate shuttle (MAS) was measured. Specifically, 50. Mu.l of the mitochondrial suspension was mixed with 2ml of the assay (300 mM 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), and pH 7.4. The oxidation of NADH was monitored at a constant temperature of 37℃for 4 minutes at 340 nm. 4mM malic acid and 4mM glutamic acid (final concentration) were added to initiate the malic-aspartic acid shuttle activity. The dose of malic/aspartic shuttle activity was measured at 340nm for 4 minutes.
(2) Assessment of lipid peroxidation degree by Malondialdehyde (MDA)
After the cell suspension was treated after co-culturing the anti-aging actives of example 1 with human keratinocytes at various concentrations (0.5%, 1%, 2.5%) for 24 hours, MDA levels were measured using malondialdehyde content detection kit.
Test results:
(1) Malic acid/aspartic acid shuttle assay: results in young groups of cells (cells from 35 year old donors) the anti-aging actives shown in figure 1 increased malate/aspartate shuttle activity by 20%, 23%, 25% at concentrations of 0.5%, 1%, 2.5%, respectively; results in cells of the aging group (cells from 62 year old donors) the anti-aging actives shown in figure 2 increased malate/aspartate shuttle activity by 18%, 24%, 28% at concentrations of 0.5%, 1%, 2.5%, respectively. The anti-aging active substance can effectively promote the function of mitochondria, thereby realizing the anti-aging function.
(2) Malondialdehyde (MDA) evaluation of lipid peroxidation degree: the final product of lipid peroxidation reaction in organism is malondialdehyde, which can cause cross-linking polymerization of living macromolecules such as protein, nucleic acid and the like, has cytotoxicity, the content of which is an important parameter reflecting the oxidation potential capability of organism, can reflect the lipid peroxidation rate and strength of organism, and can also indirectly reflect the tissue peroxidation damage degree, and the results in figure 3 show that the anti-aging active substance in the embodiment 1 has remarkable protective effect, and the anti-physiological lipid peroxidation is 24%, 30% and 33% respectively at the concentrations of 0.5%, 1.0% and 2.5%.
