Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to an anti-aging composition, and a preparation method and application thereof.
Background
With age, skin can develop aging phenomena including fine lines, sagging skin, etc., due to the reduction of collagen and elastin in the skin, and damage to the skin by free radicals. The phenomenon of skin aging is more and more obvious, and how to effectively resist the aging is the research focus in the field of skin care. At present, the existing anti-aging products in the market mainly aim at repairing existing deep wrinkles, most of the products only adopt a single component to achieve the effect of short-term wrinkle reduction, and skin care products aiming at the improvement of the comprehensive state of skin are relatively few or poor in use effect, or the skin feel is greasy due to the addition of excessive components, even the irritation is large, so that the anti-aging effect is limited to a certain extent.
Therefore, it is highly desirable to develop a product that is mild, non-irritating, non-greasy, and effective against the elderly.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems in the prior art described above. Therefore, the invention provides an anti-aging composition, a preparation method and application thereof, and the anti-aging composition is mild, non-irritating, non-greasy, and has the effects of resisting oxidation, tightening and resisting wrinkle, thereby achieving the effect of effectively resisting aging.
In a first aspect the present invention provides an anti-presbyopia composition comprising the following components: oat kernel oil, grape seed oil, avocado oil, camellia seed oil and spilanthes extract.
Specifically, the efficacy of each component in the anti-aging composition of the invention is as follows:
the grape seed oil contains linoleic acid, which can maintain the skin barrier and channel functions, is easy to be absorbed by skin, can deeply nourish and condition skin cells, has the function of scavenging free radicals, can promote the moderate crosslinking of collagen, and can prevent wrinkles and vesicles from occurring on skin. In addition, the mass fraction of VE in grape seed oil is about 360.20 mug/g, and VE can accelerate the removal of damaged cells and senescent cells and has the function of delaying senescence. Grape seed oil is rich in vitamins, minerals and flavanols (procyanidins) and helps to strengthen collagen and elastin, which make up connective tissue of the skin and joints. Omega-6 linoleic acid content in grapeseed oil is particularly high (about 76%), so the texture is fresh and easy to penetrate into deep skin. The grape seed extract has the function of conditioning, and simultaneously has the effect of astringing, so that the grape seed extract can condition skin. Grape seed oil is directly coated on skin and is easily absorbed by skin. The grape seed oil can also accelerate metabolism of skin, quicken the updating speed of skin, protect skin epidermal cells and new cells, protect skin moisture and has a certain moisturizing effect.
The camellia seed oil is rich in unit unsaturated oleic acid (about 80%), and the camellia seed oil does not block pores and is not greasy because of the tannin component. The camellia seed oil belongs to astringent vegetable oil, and is more suitable for treating oily or problematic skin than other oil products rich in oleic acid. The camellia seed oil is dry and cold in nature and can prevent skin aging. The camellia seed oil has the effects of moisturizing and moisturizing skin; in addition, the plant polyphenol, vitamin A, B, C, E and other antioxidants are protected from ultraviolet rays, environment and free radicals. The camellia seed oil is also easily absorbed by skin, and the plant squalene component contained in the camellia seed oil can nourish and maintain skin health.
About 20% of avocado oil is unsaturated linoleic acid, about 12% is rare palmitoleic acid, which nourishes the skin and maintains the health of the stratum corneum, wherein the avocado oil is also rich in vitamin A, B, E, protein and amino acids, and trace amounts of lecithin, and the avocado oil promotes collagen proliferation of dermis (middle layer of skin), and the plant sterol component thereof maintains collagen and skin structure, prevents senile plaques and cell wall weakening, simultaneously relieves inflammation symptoms, promotes tissue regeneration, and maintains the barrier function of the skin. Avocado oil is a few carotenoid-rich vegetable oils that are naturally protected from the hazards of ultraviolet light.
The oat kernel oil has a balance of oleic acid and linoleic acid, about 40% each, which is particularly beneficial to the stratum corneum of the skin. Palmitic acid is a fatty acid with a shorter carbon chain, which can sooth and protect the outer skin. Oat kernel oil is also rich in vitamin E, antioxidants and carotenoids. Oat kernel oil contains more than 20 unique polyphenol components and can resist inflammation, hyperplasia and itching. Notably, anthranilamide (Avenanthramide), a powerful antioxidant, can protect against fungal attack. The beta-glucan (beta-glucan) component of oat kernel oil is rich in polysaccharides, soluble fiber and phospholipids.
The spilanthol extract is rich in alkylamides and is considered a natural alternative to botulinum toxin; the dermal structure can be improved by stimulating the activity of fibroblasts to tighten skin, and the skin care composition can treat dermatitis, enhance the resistance of capillaries, eliminate free radical oxidation resistance and relieve aging, and has a certain inhibition effect on melanocytes. The spilanthum flower extract has the effects of improving dermis structure, tightening skin, treating dermatitis, enhancing capillary resistance, eliminating free radical, resisting oxidation, and relieving aging.
The composition obtained by compounding a plurality of specific vegetable oils and extracts can supplement lipids secreted by the skin and supplement the lipids lacking in the skin, and meanwhile, the vegetable oils contain antioxidants, so that the health function of skin cells is maintained by natural and nutritional sun-screening substances; the components in the composition have synergistic effect, promote the moderate crosslinking of collagen from multiple angles and all directions, prevent skin from wrinkling and vesicular, accelerate the removal of damaged cells and aging cells, and have the effects of resisting oxidation, tightening and resisting wrinkle, thereby achieving the purpose of effectively resisting the primary aging.

Then 1mL of the sample to be tested is added, then 0.4mL of 25mmol/L pyrogallol solution which is preheated for 20min in a water bath at 25 ℃ is added, after being uniformly mixed, the mixture is reacted for 5min in the water bath at 25 ℃, and 1.0mL of 8mol/L hydrochloric acid is added to stop the reaction. The absorbance was measured at 299nm using Tris-HCl buffer as reference.
Blank control experiment: the test sample was replaced with only 1mL of ethanol, and the other steps were unchanged. The clearance (D) is calculated according to equation (1).
D (%) = [1- (A2/A1) ] ×100% formula (1);
1) Wherein A1 is the absorbance value of the blank; a2 is the absorbance value of the sample to be tested after the test.
The test results are shown in Table 5.
TABLE 5
As can be seen from Table 5, the anti-aging compositions of examples 1 to 11 all had better radical scavenging ability, but the effects of examples 1 to 11 were not achieved by using only a single component (comparative examples 1 to 5), or a composition lacking any one of the components (comparative examples 6 to 10), or by replacing the components of example 1 with other components having similar effects (comparative examples 11 to 15).
Test example 3 tightening human efficacy test
Test article: essential oils of application examples 1 to 15 and application comparative examples 1 to 16.
The experimental method comprises the following steps: 310 groups of subjects with wrinkles on their periocular skin (30-45 years old) were selected as compactly anti-wrinkle efficacy test volunteers (the same sample was used for every 10 volunteers). The subjects used the product once a day earlier than the eyes, before using (D0), on the 7 th day (D7) and on the 14 th day (D14), after waiting 20min for the cleaning face of the subjects under the conditions of the temperature of 21+/-1 ℃ and the humidity of 50+/-10%, the face elasticity-R2 value is measured, and the tightening effect of the product on the skin of the human body is comprehensively evaluated.
Test instrument: skin elasticity tester MPA580 (manufactured by CK company, germany).
By measuring skin elasticity-R2 value, rate of change of elasticity (R2 value): refers to the rate of change of skin elasticity after application of the product versus before application. A positive value indicates an increase in the ratio of the maximum tensile displacement of the skin, and a negative value indicates a decrease in the ratio of the maximum tensile displacement of the skin, the worse the skin elasticity; to evaluate the tightening efficacy of the product.
And (3) result judgment: the result of the change of the instrument test parameter (elasticity R2 value) is improved after the product is used and any visit point is compared with that before the product is used, the product is considered to have the tightening effect, otherwise, the product is considered to not have the tightening effect. The test results are shown in Table 6.

As can be seen from table 6, the essential oils of application examples 1 to 15 all have a tightening effect, but the content of the anti-aging composition of application example 4 is too low (less than 5%), and the effect is reduced; the anti-aging composition in application example 5 has too high content (more than 50%), the R2 change rate is lower, the cosmetic is easy to be too greasy, the use feel is poor, the nutrition ingredients are difficult to absorb, pores can be blocked, and the effect of the cosmetic is affected; the effect of application examples 1 to 15 could not be achieved by using only a single component (application comparative examples 2 to 6), or a composition lacking any one of the components (application comparative examples 7 to 11), or by replacing the components in the anti-aging composition of the present invention with other components having similar effects (application comparative examples 12 to 16).
Test example 4 anti-wrinkle human efficacy test
Test article: essential oils of application examples 1 to 15 and application comparative examples 1 to 16.
The testing method comprises the following steps: the population (30-45 years old) 310 of subjects with wrinkles on the skin around eyes was selected as a tightening anti-wrinkle efficacy test volunteer (the same sample was used for every 10 volunteers)) (same as the volunteer in test example 3), and the subjects used once a day each time after the eyes, and after the time of use (D0), 7 th day (D7) and 14 th day (D14), the subjects were subjected to face photographing with VISIA 7 after waiting for 20 minutes at a temperature of 21±1 ℃ and a humidity of 50±10%, and the number of wrinkles around the eyes (bar number), the total area number of wrinkles, the average length number of wrinkles, and the area ratio number of wrinkles were measured to evaluate the anti-wrinkle efficacy of the products.
Average length value change rate of wrinkles: refers to the average length of wrinkles around the eyes after application of the product versus the rate of change before application. Positive values indicate an increase in the average length of periocular wrinkles, the longer the average length of periocular wrinkles; negative values indicate a decrease in the average length of periocular wrinkles, the shorter the average length of periocular wrinkles.
Wrinkle number (bar) value change rate: refers to the number of wrinkles around the eyes (bars) after use of the product versus the rate of change before use. Positive values indicate an increase in the number of periocular wrinkles, the more periocular wrinkles; negative values indicate a decrease in the number of periocular wrinkles, the fewer periocular wrinkles.
Total area value change rate of wrinkles: refers to the total area of periocular wrinkles after use of the product versus the rate of change before use. Positive values indicate that the total area of periocular wrinkles increases, the more periocular wrinkles are; negative values indicate that the total area of periocular wrinkles is reduced and that periocular wrinkles are reduced.
Wrinkle area ratio change rate: refers to the ratio of the area of wrinkles around the eyes after use of the product versus the rate of change before use. Positive values indicate an increase in the area ratio of periocular wrinkles, the more periocular wrinkles; negative values indicate a decrease in the area of periocular wrinkles, the fewer periocular wrinkles.
