Description

Technical Field

[0001] The invention relates to the field of cosmetic foods, and in particular to a composition for improving skin condition and application thereof. Background Art

[0002] As people pay more and more attention to beauty and health, oral beauty products are becoming more and more popular due to their convenience and intrinsic conditioning effects. In the prior art, oral beauty products with a single ingredient have limited effects, while compound plant extracts have attracted attention due to their multi-effects.

[0003] Oral beauty products on the market often only target a specific problem, such as anti-oxidation or whitening, but lack the ability to comprehensively improve skin condition. Consumers need to take multiple products at the same time, which not only increases consumption costs but also makes use complicated. Existing oral beauty products are mainly liquid beverages, capsules, tablets, and powders. The taste and convenience of oral beauty products are also the focus of consumers. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a composition for improving skin condition, which can improve skin condition after taking and has the effects of anti-oxidation, whitening and improving skin elasticity.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides a composition for improving skin condition, comprising an antioxidant composition and a whitening and brightening composition; the antioxidant composition comprises concentrated powder of Pleurotus eryngii and kiwi seed extract; the whitening and brightening composition comprises concentrated powder of musk melon and osmanthus fragrans pollen; the mass ratio of the antioxidant composition and the whitening and brightening composition is antioxidant composition: whitening and brightening composition = (0.07-0.35): (0.3-0.75).

[0007] Pleurotus eryngii concentrated powder is extracted from Pleurotus eryngii seeds through a series of deep processing techniques. Pleurotus eryngii concentrated powder contains ergothioneine; ergothioneine is a rare natural antioxidant amino acid, a naturally occurring cell protector and antioxidant in the human body, which can repair DNA telomere length, resist cell aging, inhibit the production of melanin, and has multiple physiological functions such as scavenging free radicals, maintaining DNA synthesis and normal cell growth. The human body cannot synthesize ergothioneine by itself and must be ingested from food. Kiwi seed extract is derived from the seeds of Actinidia chinensis Planch, a plant of the Actinidia family. It is rich in polyphenols, such as quercetin and kaempferol, and has antioxidant properties such as scavenging oxygen free radicals, anti-acne, anti-inflammatory, and antibacterial capabilities, and also has anti-wrinkle and moisturizing properties. Melon concentrated powder is rich in active ingredients such as SOD, VC, polyphenols, and oligoflavanones, and has extremely high antioxidant activity. It can promote the synthesis of collagen, reduce the color and number of age spots, and improve skin color and brightness. Osmanthus fragrans contains a large number of active natural products, among which verbascoside is the most important phenylethanol glycoside compound. Osmanthus pollen (PHEG20), which is rich in verbascoside, salidroside, and privet glycoside, has good effects in anti-aging and whitening, relieving chronic fatigue, and improving male function. The present invention uses concentrated powder of Pleurotus eryngii, kiwi seed extract, concentrated melon powder, and osmanthus pollen in combination, and synergizes in terms of anti-oxidation, whitening and brightening, reducing melanin, and increasing skin elasticity. Orally taking a food containing the composition for improving skin condition can improve skin condition, achieve the comprehensive effects of anti-oxidation, whitening, and improving skin elasticity, and solve skin problems more comprehensively.

[0008] Preferably, in the antioxidant composition, the mass ratio of Pleurotus eryngii concentrated powder and kiwi seed extract is Pleurotus eryngii concentrated powder: kiwi seed extract = (0.06-0.15): (0.01-0.2); in the whitening and brightening composition, the mass ratio of melon concentrated powder and osmanthus fragrans pollen is melon concentrated powder: osmanthus fragrans pollen = (0.05-0.25): (0.1-0.5).

[0009] More preferably, in the antioxidant composition, the mass ratio of Pleurotus eryngii concentrated powder and kiwi seed extract is Pleurotus eryngii concentrated powder: kiwi seed extract = (0.08-0.15): (0.1-0.2); in the whitening and brightening composition, the mass ratio of melon concentrated powder and osmanthus fragrans pollen is melon concentrated powder: osmanthus fragrans pollen = (0.1-0.25): (0.1-0.5).

[0010] The compounding of Pleurotus eryngii concentrated powder, kiwi seed extract, melon concentrated powder and osmanthus pollen within the above range has a very good effect of improving skin elasticity, and the R2 value improvement rate after 4 weeks of consumption is above 19.89%. Long-term consumption of the composition for improving skin condition can increase skin elasticity and has obvious anti-aging effect.

[0011] More preferably, the mass ratio of the concentrated Pleurotus eryngii powder, kiwi seed extract, concentrated melon powder and osmanthus fragrans pollen is concentrated Pleurotus eryngii powder: kiwi seed extract: concentrated melon powder: osmanthus fragrans pollen = 0.08:0.1:0.15:0.3.

[0043] The components and proportions of the beauty foods described in the various embodiments are shown in Table 1.

[0044] Table 1 (total weight parts are 100 parts)

[0045]

[0046]

[0047] The method for preparing the beauty food described in Examples 1-6 comprises the following steps:

[0048] (1) Weigh each component according to the above weight parts;

[0049] (2) Erythritol and a thickener are mixed at 70-80° C. to obtain a mixture A; Pleurotus erythrorhizonii concentrated powder, kiwi seed extract, melon concentrated powder, osmanthus pollen, steviol glycoside, and part of water are mixed at 70-80° C. to obtain a mixture B; citric acid, sodium citrate, and part of water are mixed at 70-80° C. to obtain a mixture C; edible flavors and part of water are mixed to obtain a mixture D;

[0051] The only difference between the preparation method of the cosmetic food described in Example 7 and that in Example 1 is that the sterilization temperature in step (3) is 95° C. and the sterilization time is 10 min. The remaining steps and parameters are the same as those in Example 1.

[0052] Comparative Examples 1-5:

[0053] Comparative Examples 1-5 are comparative examples of the beauty food of the present invention, and the beauty food is specifically a jelly.

[0054] The beauty food comprises a composition for improving skin condition and auxiliary materials; the composition for improving skin condition comprises an antioxidant composition and a whitening and brightening composition; the antioxidant composition comprises concentrated powder of Pleurotus eryngii and kiwi seed extract; the whitening and brightening composition comprises concentrated powder of melon and osmanthus fragrans pollen.

[0055] The components and proportions of the beauty foods in each comparative example are shown in Table 2. The preparation method of the beauty foods is the same as that of the examples.

[0056] Table 2 (total weight parts are 100 parts)

[0057]

[0058] Among them, the only difference between Comparative Examples 1-4 and Example 2 is that Comparative Example 1 does not add Pleurotus eryngii concentrated powder, Comparative Example 2 does not add kiwi seed extract, Comparative Example 3 does not add melon concentrated powder, and Comparative Example 4 does not add Osmanthus fragrans pollen. The other components and proportions are the same as Example 2.

[0059] Test Example 1:

[0060] 1. Experimental purpose

[0061] 130 healthy female subjects aged between 30 and 60 were screened and randomly divided into 13 groups, namely, a blank group, Example 1-7 groups, and Comparative Example 1-5 groups. The beauty foods prepared in Example 1-7 and Comparative Example 1-5 were used as test products. One bag of the test product was consumed every day, 100 g / bag, and the test product was used continuously for 4 weeks ( Figure 1 ), tested skin elasticity (R2), skin melanin content (MI), skin color (L*, b*) and other indicators before using the product (basic value), 2 weeks and 4 weeks after using the product. The anti-aging and whitening effects of the product were evaluated by the changes in skin indicators before and after using the product.

[0062] 2. Test process

[0063] On the day of the test, the subjects washed their faces in the morning without using any skin care products. When they came for the test, they all used clean water to clean their faces, wiped them clean with dry, lint-free paper towels, and sat in a constant temperature and humidity environment for at least 30 minutes. After 30 minutes, the researchers conducted instrumental tests on the research parameters. The researchers explained the product usage to the subjects, emphasized the requirements for the use of skin care products during the test period, and distributed the products and usage records to them. All measurements were conducted in a constant temperature and humidity room with a temperature of 20-22°C and a relative humidity of 40-60%.

[0064] 3. Test methods

[0065] 3.1 Skin elasticity R2 value

[0066] The skin elasticity tester MPA580 (Cutometer probe) is used to measure the skin elasticity R2 value (the closer the R2 value is to 100%, the better the skin elasticity). Based on the suction and stretching principles, a negative pressure is generated on the surface of the skin being tested to suck the skin into a specific test probe. The depth of the skin sucked into the test probe is measured by a non-contact optical test system. The test probe includes a light transmitter and a receiver. The ratio of light (the ratio of emitted light to received light) is proportional to the depth of the skin being sucked into it. A curve of the relationship between the length and time of skin stretching is obtained, and then the skin's elasticity is determined by MPA software analysis. In this experiment, the R2 value is used as the parameter of skin elasticity.

[0067] Table 3 Skin elasticity R2 value results

[0068]

[0069] The test results of the skin elasticity R2 value are shown in Table 3. Regardless of whether the test product of the embodiment or the comparative example is taken, the difference in the R2 value improvement rate after 2 weeks of consumption is not large; and after the end of the consumption period (4 weeks), compared with comparative examples 1-5, the R2 value improvement rate of the embodiment is significantly improved, that is, the composition for improving skin condition prepared by embodiments 1-7 has a very good effect of improving skin elasticity. Compared with before consumption, the R2 value improvement rate after 4 weeks of consumption is more than 17.83%, indicating that after long-term consumption of the composition for improving skin condition, skin elasticity increases and the anti-aging effect will be more obvious. Compared with embodiments 1-7, the composition for improving skin condition prepared by comparative examples 1-5 lacks any active component or the ratio of each component exceeds the range specified in the present invention, and its effect of improving skin elasticity is poor.

[0070] Compared with Examples 1-7, the compositions for improving skin condition prepared in Examples 5 and 6 have a better effect on improving skin elasticity. The amount of the composition added in Example 6 is significantly more than that in Example 5, but the overall effect of the two is not much different, indicating that increasing the amount of the composition added can improve skin elasticity to a certain extent, but after adding to a certain extent, the improvement in the effect is limited. Based on this, Example 5 is selected as the best example.

[0071] 3.2 Skin melanin content (MI)

[0072] The melanin content of the skin is collected using the mexameter. This measurement is based on the principle of spectral absorption (RGB), and the melanin content in the skin is determined by measuring the amount of reflection of light of a specific wavelength on human skin. The transmitter of the instrument probe emits three wavelengths of light on the surface of the skin, and the receiver measures the light reflected back by the skin. The amount of emitted light is certain, so the amount of light absorbed by the skin can be measured, thereby measuring the melanin content of the skin. The higher the MI value, the higher the melanin content of the skin.

[0075] The results of the skin melanin test are shown in Table 4. Compared with the blank group, after consuming the test products of the embodiments and the comparative examples, the MI values ​​were significantly reduced, indicating that the composition for improving skin condition prepared by the present invention has the effect of reducing melanin. Compared with the comparative example and the blank group, the MI values ​​of the test products of edible embodiments 1-7 were all reduced by more than 6.2, while in comparative examples 1-5, due to the lack of one of the raw material components or the raw material components exceeding the scope of the present invention, the MI values ​​were all reduced by less than 6.2, which shows that the composition for improving skin condition obtained by compounding Pleurotus eryngii concentrated powder, kiwi seed extract, melon concentrated powder and osmanthus pollen of the present invention has a good whitening effect. The MI values ​​of the test products of edible embodiments 5 and 6 decreased more than those of other embodiments, and the addition amount of the composition of embodiment 6 was significantly more than that of embodiment 5, but the overall effect of the two was not much different. Considering the cost saving of the product, embodiment 5 was selected as the best embodiment.

[0076] Compared with Example 5, Example 7 has a MI decrease value of 2.4, which indicates that changes in sterilization temperature and sterilization time will also affect the whitening effect. When the heating sterilization temperature is 85°C and the sterilization time is 15 minutes, the composition can have a better whitening effect.

[0077] 3.3VISIA-CR facial image acquisition skin color

[0078] Facial VISIA-CR images are used for facial image acquisition. VISIA-CR is a facial imaging analysis system dedicated to scientific research and clinical trials. It can be used to directly observe skin characteristics such as spots, skin color, pore size, glossiness, and wrinkles. By analyzing the L* and b* values ​​of skin color, the skin's whitening and glossiness can be evaluated, as well as the effect of the product on improving skin color.

[0079] L* value: represents the brightness of skin color. The higher the L* value, the brighter the skin looks.

[0080] b* value: represents the yellow-blue axis of skin color. The higher the b value, the yellower the skin; the lower the b value, the bluer the skin (i.e., the fairer).

[0081] An increase in L value and a decrease in b* value generally indicates brighter skin.

[0082] Table 5 Skin color L* detection results

[0083]

[0084]

[0085] Table 6 Skin color b* value detection results

[0086]

[0087] The test results of the L* value and b* value of skin color are shown in Tables 5-6. After the consumption period, except for Comparative Example 5, the L* value and b* value of the embodiments and other comparative examples changed to a certain extent. After consuming the test product for 4 weeks, compared with the baseline value, the L* value increased as a whole and the b* value decreased, indicating that the composition has the effect of brightening and whitening the skin. The ratio of each component in the composition for improving skin condition prepared in Comparative Example 5 exceeds the range specified in the present invention, and the added amount is small, and there is almost no effect of whitening the skin. Compared with Example 5, the effect of brightening and whitening the skin in Example 7 is reduced to a certain extent, which may be because the higher sterilization temperature causes the effect of certain ingredients in the composition to weaken in improving the skin condition.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
