In addition, the mugwort leaf extract can also inhibit the activity of tyrosinase and has the effect of inhibiting the synthesis of cell melanin, and has a certain whitening effect, and is a potential natural whitening active ingredient. The guavaberry fruit extract contains special polysaccharides, which can significantly increase the water content of the skin horny layer. The mugwort leaf extract can synergistically enhance the guavaberry fruit extract, and together improve the skin inflammation, thereby reducing the inflammation and blockage of pores, and better balancing the secretion of skin oil.

[0037] 2.The application adopts cell wall breaking and carbon dioxide supercritical fluid extraction method to prepare extract containing Artemisia Argyi extract. The cell wall and cell membrane structure of Artemisia Argyi cells can be destroyed by liquid nitrogen low-temperature breaking technology, so that the active substances wrapped inside the cells are fully exposed. The active components in Artemisia Argyi, such as eucalyptol, camphor, thujaketone and other main volatile oil components, and part of flavonoids, which are easy to volatilize, oxidize and unstable to heat, can be effectively avoided from being destroyed, decomposed or volatilized, so that the biological activity and natural flavor are retained. Meanwhile, the cell wall breaking pretreatment greatly shortens the time required for supercritical carbon dioxide penetration and mass transfer. The carbon dioxide supercritical fluid extraction method has strong penetration and dissolution capacity, and can quickly and deeply penetrate into the inside of the broken material, directly dissolve the target components. Meanwhile, the supercritical carbon dioxide fluid has the characteristics of low viscosity and high diffusion coefficient, and the mass transfer rate is much faster than that of liquid solvent. The cell wall breaking and carbon dioxide supercritical fluid extraction method makes the whole extraction process take less time than traditional solvent extraction or steam distillation, and can retain the active components in Artemisia Argyi. Compared with traditional distillation and solvent extraction, the method has the advantages of simple operation, high efficiency, high safety and high yield. DETAILED DESCRIPTION

[0057] Experimental detection:

[0058] The skin moisture change test, transdermal water loss change test, skin red zone hemoglobin change test, and skin gloss change test were performed on the examples and comparative examples. 140 volunteers were divided into 7 groups, and the 7 groups of volunteers respectively used the samples of examples 1-3 and comparative examples 1-4 for testing. The experimental results are shown in Tables 2-3.

[0059] (1) Skin keratin layer moisture content

[0060] Test instrument: Corneometer CM 825

[0061] Test principle: The capacitance method is used to measure the moisture content of human skin keratin layer. The difference between the dielectric constant of water (81) and that of other substances (<7) is significant. According to the difference in the moisture content of the skin keratin layer, the measured capacitance value of the skin is different, and the parameter can represent the moisture content of the skin keratin layer. The higher the value, the higher the skin moisture content.

[0062] Test time point: before use and 7 days after use.

[0063] Test method: Before the test, the subjects need to clean the skin on the inner side of the forearm uniformly. The cleaning method is to wipe clean with dry facial tissue paper. The test site cannot use any samples (cosmetics or external drugs) for 3 days before the test, and cannot contact water for 3 hours before the test; the subjects should mark the test area on the inner side of the forearm, and the test area should be 3*3 cm2; before the test, the subjects should sit in the laboratory at a temperature of 20-22℃ and a relative humidity of 40%-60% for at least 30 minutes, and cannot drink water and beverages. The forearm is exposed and placed in the test state, and remains relaxed; the skin moisture content of the test area skin is measured and selected, and recorded as 0d.

[0064] Sample (sample site, sample amount, sample method): After wetting the skin, take an appropriate amount of sample and wash the test area for 10 circles, then rinse with clean water, press gently with a non-dusting paper towel, and dry the surface moisture. Use once a day.

[0065] After using the sample: 7 days later, the skin moisture content of the test area was measured and recorded as 7 days.

[0066] Self-rate of change before and after sampling: [(value after sampling - value before sampling) / value before sampling] * 100%

[0067] (2) Transepidermal water loss test

[0068] Testing instrument: Delfin VaPoMeter (Skin Transepidermal Moisture Loss Measurement Instrument)

[0069] Test principle: Based on Fick's law of diffusion, the water vapor partial pressure gradient at different points per unit time and unit cross-sectional area is used to obtain the transepidermal water loss value. A decrease in the value indicates that the rate of skin moisture evaporation is slowed down, and the skin barrier function is improved.

[0070] Testing time points: before using the product and 7 days after using the product.

[0071] Test Method: Before the test, subjects must clean the inner forearm skin of both hands uniformly by wiping with a dry tissue. No samples (cosmetics or topical medications) should be used on the test site for 3 days prior to the test, and the site should not come into contact with water for 3 hours before the test. The test area should be marked on the inner forearm skin of both hands, with an area of ​​3*3 cm. Before the test, subjects should sit quietly for at least 30 minutes in a laboratory with a temperature of 20℃~22℃ and a relative humidity of 40%~60%, without drinking water or beverages, with the forearms exposed and placed in the test position, remaining relaxed. The transepidermal water loss of the test area skin is measured and recorded as 0 days.

[0072] Application (sampling site, amount, and method): After wetting the skin, apply an appropriate amount of sample to the test area and massage in circular motions for 10 circles. Rinse thoroughly with clean water and gently pat dry with a lint-free tissue. Use once daily.

[0073] After using the sample: 7 days later, the transepidermal water loss of the skin in the test area was measured and recorded as 7 days.

[0074] Self-rate of change before and after sampling: [(value after sampling - value before sampling) / value before sampling] * 100%

[0075] (3) Skin red area hemoglobin test

[0076] Testing instrument: Skin Color ITA° (SkinColorCatch)

[0077] Test principle: The reflected light from the skin is received by the XYZ sensor inside the probe, and the skin color is measured using the XYZ three-primary-color method. This yields a quantified erythema index (E value); the higher the value, the redder the skin.

[0078] Treatment of skin abrasions with sodium lauryl sulfate (SLS): Sodium lauryl sulfate (SLS) is a detergent ingredient. A certain concentration of SLS applied to the skin can cause skin damage and induce inflammation, manifesting as increased blood flow due to dilation of local dermal microvessels. Simultaneously, the skin barrier function of the epidermis is disrupted due to the skin damage.

[0079] Testing time points: before using the product and 7 days after using the product.

[0080] Test Method: Before the test, subjects must clean the skin on the inner forearms of both hands uniformly by wiping with a dry tissue. No samples (cosmetics or topical medications) should be used on the test site for 3 days prior to the test, and the area should not come into contact with water for 3 hours before the test. One day before the test, a 1% SLS solution should be applied to the broken skin, and the patch should be removed after 24 hours. The test should be conducted 30 minutes later. The test area should be marked on the inner forearms of both hands, with an area of ​​3*3 cm. Before the test, subjects should sit quietly for at least 30 minutes in a laboratory with a temperature of 20℃~22℃ and a relative humidity of 40%~60%, without drinking water or beverages. The forearms should be exposed and placed in the test position, remaining relaxed. The Erythema Index (E) value of the skin in the test area should be measured and recorded as 0 days.

[0081] Application (sampling site, amount, and method): After wetting the skin, apply an appropriate amount of sample to the test area and massage in circular motions for 10 circles. Rinse thoroughly with clean water and gently pat dry with a lint-free tissue. Use once daily.

[0082] After using the sample: 7 days later, the erythema index E value of the skin in the test area was measured and recorded as 7d.

[0083] Self-rate of change before and after sampling: [(value after sampling - value before sampling) / value before sampling] * 100%

[0084] (4) Skin luster test

[0085] Testing instrument: Skin glossiness test probe (Courage+Khazaka Glossymeter GL200)

[0086] Test principle: Skin surface gloss is reflected by the direct reflection and diffuse reflection of light incident on the skin surface. A skin gloss test probe measures skin gloss; the higher the value, the better the skin gloss.

[0087] Testing time points: before using the product and 7 days after using the product.

[0088] Test Method: Before the test, subjects must uniformly clean the skin on the inner forearms of both hands by wiping with a dry tissue. No samples (cosmetics or topical medications) should be used on the test site for 3 days prior to the test, and the site should not come into contact with water for 3 hours before the test. The test area should be marked on the inner forearms of both hands, with an area of ​​3*3 cm. Before the test, subjects should sit quietly for at least 30 minutes in a laboratory with a temperature of 20℃~22℃ and a relative humidity of 40%~60%, without drinking water or beverages, with the forearms exposed and placed in the test position, remaining relaxed. The glossiness of the skin in the test area will be measured and recorded as 0 days.

[0089] Application (sampling site, amount, and method): After wetting the skin, apply an appropriate amount of sample to the test area and massage in circular motions for 10 circles. Rinse thoroughly with clean water and gently pat dry with a lint-free tissue. Use once daily.

[0090] After using the sample: 7 days later, the gloss of the skin in the test area was measured and recorded as 7d.

[0091] Self-rate of change before and after sampling: [(value after sampling - value before sampling) / value before sampling] * 100%

[0092] Table 2

[0093]

[0094] Table 3

[0095]

[0096] The test results of Examples 1-3 show that after using the compositions of Examples 1-3 for 7 days, the moisture content of the stratum corneum and the skin luster are improved, while the transepidermal water loss and the heme content in the erythema area of ​​the skin are significantly reduced. After 7 days of use, the moisture content of the stratum corneum is further increased, and the heme content in the erythema area of ​​the skin is further reduced, indicating that the composition of the present invention has the effects of long-lasting moisturizing, soothing skin erythema and whitening.

[0097] A comparison of the test results of Examples 1-3 and Comparative Example 4 shows that the addition amount of the plant efficacy composition in Examples 1-3 is more effective than that in Comparative Example 4, indicating that the addition amount of the plant efficacy composition in Examples 1-3 is the preferred addition amount. Beyond this range, even if the addition amount of the plant efficacy composition is increased, the efficacy of the composition is only slightly improved, but the cost increases.

[0098] By comparing the test results of Example 2 and Comparative Example 1, it can be seen that the plant-based active ingredients can enhance the long-lasting moisturizing ability, soothing ability and skin radiance of the composition.

[0099] Comparing the test results of Example 2 with those of Comparative Examples 2 and 3, it can be seen that the effect of adding both Artemisia argyi extract and Rosa canis extract is better than adding either Artemisia argyi extract or Rosa canis extract, indicating that Artemisia argyi extract and Rosa canis extract have a synergistic effect.

[0100] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0101] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0102] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
