Description

Technical Field

[0001] This invention relates to the field of herbal skincare technology, and in particular to a herbal skincare mask powder that clears the liver, dispels wind, disperses stagnation, and invigorates blood circulation. Background Technology

[0002] With the fast pace of life, irregular schedules, changes in dietary structure, and increased external environmental stimuli, problems such as facial shine, redness and burning, acne, nodular bumps, dryness, roughness, and post-acne dullness are becoming increasingly common among people with oily, combination, and sensitive skin. Modern skin research suggests that these facial conditions are usually related to factors such as excessive sebum secretion, abnormal keratinization of hair follicle openings, changes in skin microecology, release of inflammatory factors, and fluctuations in skin barrier function. Therefore, the development of skincare products has gradually shifted from simple cleansing and oil control to a comprehensive care model that combines soothing, conditioning, repairing, and improving skin tone and appearance. Traditional Chinese medicine is naturally derived and rich in various components, containing flavonoids, phenolic acids, polysaccharides, volatile components, and saponins, among other active substances. It has a good research foundation in anti-oxidation, soothing and repairing, regulating oil appearance, and improving skin roughness.

[0003] In traditional Chinese medicine theory, facial redness, swelling, burning, persistent induration, and dark acne scars can be understood and addressed through treatments based on factors such as liver fire stagnation, external wind-heat invasion, and phlegm-blood stasis. Therefore, this study uses Prunella vulgaris, Cassia tora, and Celosia argentea as liver-clearing and nodule-dispersing components; Lonicera japonica, Chrysanthemum morifolium, Morus alba leaves, and Mentha haplocalyx as wind-dispelling and heat-clearing components; and Cicada slough, Buddleja officinalis, and Salvia miltiorrhiza as wind-dispelling, moisturizing, blood-activating, and skin-regulating components. These herbal ingredients are then formulated into a powder for topical application, creating a product development direction that combines herbal conditioning, powder absorption, patch application, and daily skin care.

[0004] Existing herbal mask powders for oily, acne-prone, and red skin care often focus on clearing heat, controlling oil, or simply soothing. Their formulations are relatively thin and lack a systematic combination of clearing the liver and dispersing nodules, relieving wind and itching, and promoting blood circulation and fading marks. They are difficult to address multiple symptoms such as redness and swelling, recurring redness, dryness and itching, uneven skin tone, and post-acne dullness at the same time. Furthermore, when applied externally, the powder is prone to problems such as dryness and tightness, rough particles, poor adherence, and insufficient comfort. Summary of the Invention

[0005] In order to solve the problems mentioned in the background art, the present invention provides a herbal skin care facial mask powder that clears the liver, dispels wind, disperses stagnation, and invigorates blood circulation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A herbal skin care facial mask powder for clearing liver heat, dispelling wind, resolving stagnation, and promoting blood circulation, wherein the herbal skin care facial mask powder comprises herbal functional powder and skin care excipient powder; The herbal functional powder includes components for clearing liver stagnation and resolving lumps, components for dispelling wind and clearing heat, and components for dispelling wind, moisturizing and promoting blood circulation. The liver-clearing and nodule-dispersing components include Prunella vulgaris, Cassia tora, and Celosia argentea. The components for dispelling wind and clearing heat include honeysuckle, chrysanthemum, mulberry leaf, and mint; The wind-dispelling, moisturizing, and blood-activating components include cicada slough, buddleja officinalis, and salvia miltiorrhiza. The skin care excipient powder includes one or more of the following: plant polysaccharide excipients, starch excipients, mineral adsorbent powders, and moisturizing protectants; When used, the herbal skincare mask powder is mixed with water, hydrosol, gel matrix, or other cosmetically acceptable liquids to form a paste or mud-like mask that can be applied externally to the skin.

[0007] Furthermore, the herbal skincare mask powder comprises the following components: 10-30 parts of Prunella vulgaris, 5-20 parts of Cassia tora, 5-20 parts of Celosia argentea, 5-20 parts of Lonicera japonica, 5-18 parts of Chrysanthemum morifolium, 5-18 parts of Mulberry leaf, 1-8 parts of Mentha haplocalyx, 1-8 parts of Cicadae periostracum, 3-15 parts of Buddleja officinalis, 5-25 parts of Salvia miltiorrhiza, and 10-60 parts of skin care excipient powder.

[0008] Furthermore, in the herbal functional powder, the weight ratio of Prunella vulgaris, Cassia tora, and Celosia argentea is 1:0.3-1.2:0.3-1.2; The weight ratio of honeysuckle, chrysanthemum, mulberry leaves and mint is 1:0.3-1.5:0.3-1.5:0.05-0.5; The weight ratio of Salvia miltiorrhiza, Cicadae Periostracum and Buddleja officinalis is 1:0.05-0.8:0.1-1.0; This gives the herbal functional powder the synergistic skincare effects of clearing liver stagnation, dispelling wind and clearing heat, soothing and moisturizing, and improving dull skin tone.

[0009] Furthermore, the skin care excipient powder includes a composite modified plant polysaccharide microgel powder; The composite modified plant polysaccharide microgel powder is formed by combining okra mucopolysaccharide, low-ester pectin, carboxymethyl chitosan and natural cross-linking agent; The natural cross-linking agent includes one or more of the following: geniposide conversion products, geniposide, phytates, and polyphenolic substances; The composite modified plant polysaccharide microgel powder contains one or more water extracts, alcohol-water extracts, or freeze-dried extracts of Prunella vulgaris, Salvia miltiorrhiza, Lonicera japonica, Chrysanthemum morifolium, and Mulberry leaf.

[0010] Furthermore, the skin care excipient powder also includes modified mineral adsorbent powder; The modified mineral adsorbent powder is one or more of palygorskite, attapulgite, kaolinite, and sepiolite that have been modified by a composite of plant polysaccharides and zinc phytate. The plant polysaccharides include one or more of the following: Prunella vulgaris polysaccharide, mulberry leaf polysaccharide, okra mucopolysaccharide, tremella polysaccharide, and inulin. The modified mineral adsorbent powder is used to improve the water absorption and dispersibility, sebum adsorption and smoothness of the mask powder, and to reduce the dryness and roughness caused when the mineral powder comes into direct contact with the skin.

[0011] Furthermore, the skin care excipient powder also includes modified mineral adsorbent powder; The modified mineral adsorbent powder is one or more of palygorskite, attapulgite, kaolinite, and sepiolite that have been modified by a composite of plant polysaccharides and zinc phytate. The plant polysaccharides include one or more of the following: Prunella vulgaris polysaccharide, mulberry leaf polysaccharide, okra mucopolysaccharide, tremella polysaccharide, and inulin. The modified mineral adsorbent powder is used to improve the water absorption and dispersibility, sebum adsorption and smoothness of the mask powder, and to reduce the dryness and roughness caused when the mineral powder comes into direct contact with the skin.

[0012] Furthermore, the particle size D90 of the herbal functional powder is 10–80 μm; The particle size D90 of the skin care excipient powder is 20-200 μm; The water content of the herbal skincare mask powder is no higher than 10%. The herbal skincare mask powder also includes one or more of the following: trehalose, β-glucan, erythritol, mannitol, oat colloid powder, rice starch, lotus root starch, and kudzu root starch, to improve the moisturizing, spreadability, and comfort of the mask powder.

[0013] In addition, this invention also discloses a method for preparing a herbal skin care facial mask powder that clears the liver, dispels wind, disperses stagnation, and invigorates blood circulation, comprising the following steps: S1. Take Prunella vulgaris, Cassia tora, Celosia argentea, Lonicera japonica, Chrysanthemum morifolium, Morus alba leaves, Mentha haplocalyx, Cicadae periostracum, Buddleja officinalis and Salvia miltiorrhiza respectively, remove impurities, wash and dry at low temperature; S2. Crush the dried herbal raw materials separately, sieve them, and obtain herbal powder; S3. The herbal powder is subjected to ultra-fine grinding or low-temperature airflow grinding to obtain herbal functional powder; S4. Mix one or more of the following: plant polysaccharide excipients, starch excipients, mineral adsorbent powders, and moisturizing agents to obtain skin care excipient powders; S5. The herbal functional powder and the skin care excipient powder are mixed in proportion, and then sterilized, dried and sealed in packaging to obtain the herbal skin care mask powder; The low-temperature drying temperature is 35-65℃, and the material temperature during the ultrafine pulverization process is not higher than 60℃.

[0014] Furthermore, step S4 also includes a composite modification step: Okra polysaccharide, low-ester pectin and carboxymethyl chitosan were swollen and dispersed, and extracts of Prunella vulgaris, Salvia miltiorrhiza, Lonicera japonica, Chrysanthemum or mulberry leaf were added. Then, geniposide, phytate or polyphenol natural cross-linking agent were added for cross-linking or complexation. After drying, composite modified plant polysaccharide microgel powder was obtained. Furthermore, palygorskite, attapulgite, kaolinite or sepiolite are compounded with plant polysaccharides and zinc phytate for modification, and then dried and pulverized to obtain modified mineral adsorption powder. The composite modified plant polysaccharide microgel powder and / or modified mineral adsorbent powder are then added to the herbal functional powder to prepare a non-therapeutic skin care mask powder with soothing, oil-controlling, moisturizing, redness-reducing, roughness-reducing, and acne scar-reducing effects.

[0015] The beneficial effects of this invention are: This invention uses Prunella vulgaris, Cassia tora, and Celosia argentea as liver-clearing and nodule-dispersing components, honeysuckle, chrysanthemum, mulberry leaf, and mint as wind-dispelling and heat-clearing components, and cicada slough, Buddleja officinalis, and Salvia miltiorrhiza as wind-dispelling, moisturizing, blood-activating, and skin-regulating components to form a multi-layered herbal compound formulation system. This helps the mask powder to take into account various skin care directions such as refreshing conditioning, soothing redness, improving the appearance of facial redness and swelling, relieving dryness and itching, and improving the appearance of dullness after acne. Compared with herbal mask powders that only clear heat, control oil, or cleanse, it has more comprehensive skin care applicability.

[0016] This invention utilizes the complementary functions and balanced compatibility of multiple herbs to maintain the refreshing and gentle characteristics of herbal care while addressing issues such as dryness, tightness, or a thin skin feel that may result from simple heat-clearing and oil-controlling powders. Furthermore, moisturizing components such as Buddleja officinalis can harmonize the overall skin feel of the formula, while cicada molting and Salvia miltiorrhiza supplement the product by soothing skin discomfort and improving skin tone and appearance, respectively. This makes the product gentle and comfortable for daily topical care of oily, combination, easily reddened, and post-acne dull skin.

[0017] This invention produces herbal functional powders by removing impurities, washing, low-temperature drying, pulverizing, sieving, or ultra-fine pulverizing herbal raw materials. These powders can be compounded with skin care excipients such as plant polysaccharide excipients, starch excipients, mineral adsorbent powders, and moisturizing agents. This helps improve the fineness, dispersibility, and uniformity of the powder. When used, it can be mixed with water, hydrosol, honey, or gel matrix to form a paste or mud-like external application system, which is convenient for storage, transportation, and on-demand preparation. It also helps to improve the obvious graininess, poor skin adhesion, and unpleasant user experience that may occur with traditional coarse powder external applications. Detailed Implementation

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention discloses a herbal skincare facial mask powder for clearing liver heat, dispelling wind and stagnation, and promoting blood circulation. It is applicable to daily external care of oily skin, combination skin, skin prone to redness, acne-prone skin, and post-acne dull skin. The process includes herbal raw material pretreatment, herbal functional powder preparation, skincare excipient powder preparation, compounding and mixing, and sealing packaging. By compounding liver-clearing and stagnation-dispelling components, wind-dispelling and heat-clearing components, wind-dispelling and moisturizing components, and blood-activating and skin-regulating components, combined with powder refinement and excipient blending, the resulting facial mask powder exhibits good dispersibility, skin adhesion, refreshing and conditioning properties, soothing properties, and user comfort. The specific preparation process will be further described below.

[0020] The equipment used in the specific embodiments of this invention are all conventional equipment in the art, including electronic balances, washing tanks, hot air circulating drying ovens, vacuum drying ovens, universal pulverizers, low-temperature airflow pulverizers or ultrafine pulverizers, vibrating screens, three-dimensional mixers, ultraviolet sterilization chambers, sealing packaging machines, laser particle size analyzers, moisture analyzers, skin oil testers, skin erythema and melanin testers, transdermal water loss testers, constant temperature and humidity laboratory equipment, and conventional microbial testing equipment. The above equipment is only used to complete raw material processing, powder preparation, mixing and packaging, and performance evaluation, and does not constitute a limitation on the scope of protection of this invention.

[0021] In the following examples and comparative examples, unless otherwise stated, all quantities are by weight. When using the herbal skincare mask powder, it is mixed with purified water in a suitable ratio to form a uniform paste or mud before application. The following data and test results are simulated examples used to illustrate the feasibility of the technical solution; actual product development should be based on real test data.

[0022] Example 1, this example is the left-endpoint example of the claims.

[0023] Take 10 parts of Prunella vulgaris, 5 parts of Cassia tora, 5 parts of Celosia argentea, 5 parts of Lonicera japonica, 5 parts of Chrysanthemum morifolium, 5 parts of Morus alba leaves, 1 part of Mentha haplocalyx, 1 part of Cicadae periostracum, 3 parts of Buddleja officinalis, and 5 parts of Salvia miltiorrhiza. Remove impurities, sand, and unsuitable parts from each of the above herbal raw materials. Then, quickly wash them with purified water, drain the surface moisture, and place them in a hot air circulating drying oven at a low temperature of 35℃ to obtain dried herbal raw materials.

[0024] The dried herbal raw materials were separately fed into a universal pulverizer for initial pulverization, and then sieved to obtain herbal powder. Subsequently, the herbal powder was placed in a low-temperature airflow pulverizer for ultrafine pulverization, with the material temperature controlled not to exceed 60℃ during the pulverization process. After pulverization, it was sieved through a vibrating screen to obtain herbal functional powder. The particle size D90 of the herbal functional powder was measured to be 10 μm by a laser particle size analyzer.

[0025] Ten parts of a skin-care excipient powder were prepared. The skin-care excipient powder consisted of 2.5 parts of a composite modified plant polysaccharide microgel powder, 1.5 parts of modified mineral adsorbent powder, 4 parts of rice starch, 1.5 parts of trehalose, and 0.5 parts of β-glucan. The composite modified plant polysaccharide microgel powder was prepared by adding okra polysaccharide, low-ester pectin, and carboxymethyl chitosan to purified water and stirring until swollen. A mixed aqueous extract of Prunella vulgaris, Salvia miltiorrhiza, Chrysanthemum morifolium, and Mulberry leaf was added, followed by a small amount of genistein for cross-linking treatment to form a plant polysaccharide microgel system. The system was then freeze-dried and pulverized to obtain the composite modified plant polysaccharide microgel powder. The modified mineral adsorbent powder was prepared by dispersing palygorskite in purified water, adding Prunella vulgaris polysaccharide and zinc phytate for composite modification, and then drying, pulverizing, and sieving to obtain the modified mineral adsorbent powder.

[0026] The above-mentioned herbal functional powder and skin care excipient powder were added to a three-dimensional mixer and mixed evenly. After mixing, the mixture was sterilized by ultraviolet light and then tested by a moisture analyzer. The moisture content of the resulting herbal skin care mask powder was 8.2%. The sterilized powder was sealed and packaged to obtain the liver-clearing, wind-dispersing, stagnation-reducing, and blood-activating herbal skin care mask powder of Example 1.

[0027] Example 2, which is a preferred embodiment within the scope of the claims.

[0028] The difference between this embodiment and Embodiment 1 is that: 20 parts of Prunella vulgaris, 12 parts of Cassia tora, 12 parts of Celosia argentea, 12 parts of Lonicera japonica, 10 parts of Chrysanthemum morifolium, 10 parts of Morus alba leaves, 4 parts of Mentha haplocalyx, 4 parts of Cicadae periostracum, 8 parts of Buddleja officinalis, and 15 parts of Salvia miltiorrhiza were taken; the low-temperature drying temperature of the herbal raw materials was 45℃; after ultrafine grinding and sieving, the particle size D90 of the herbal functional powder was 35 μm.

[0029] In this embodiment, the skin-care excipient powder consists of 35 parts, comprising 12 parts of composite modified plant polysaccharide microgel powder, 8 parts of modified mineral adsorbent powder, 9 parts of rice starch, 3 parts of trehalose, 2 parts of β-glucan, and 1 part of oat colloid powder. The preparation methods of the composite modified plant polysaccharide microgel powder and the modified mineral adsorbent powder are the same as in Example 1, only the amounts are adjusted according to the above. After mixing, sterilization, and packaging, the resulting herbal skin-care mask powder has a moisture content of 6.8% and a particle size D90 of 80 μm. Other steps are the same as in Example 1.

[0030] Example 3, which is the right-endpoint example of the claims.

[0031] The difference between this embodiment and Embodiment 1 is that: 30 parts of Prunella vulgaris, 20 parts of Cassia tora, 20 parts of Celosia argentea, 20 parts of Lonicera japonica, 18 parts of Chrysanthemum morifolium, 18 parts of Morus alba leaves, 8 parts of Mentha haplocalyx, 8 parts of Cicadae periostracum, 15 parts of Buddleja officinalis, and 25 parts of Salvia miltiorrhiza were used; the low-temperature drying temperature of the herbal raw materials was 65℃; after ultrafine grinding and sieving, the particle size D90 of the herbal functional powder was 80 μm.

[0032] In this embodiment, the skin-care excipient powder consists of 60 parts, comprising 18 parts of composite modified plant polysaccharide microgel powder, 15 parts of modified mineral adsorbent powder, 15 parts of rice starch, 5 parts of trehalose, 3 parts of β-glucan, and 4 parts of mannitol. The preparation methods of the composite modified plant polysaccharide microgel powder and the modified mineral adsorbent powder are the same as in Example 1, only the amounts are adjusted according to the above. After mixing, sterilization, and packaging, the resulting herbal skin-care mask powder has a water content of 7.5% and a particle size D90 of 200 μm. Other steps are the same as in Example 1.

[0033] Comparative Example 1: This comparative example is used to verify the effect of the complete combination of ten herbs.

[0034] The difference between this comparative example and Example 2 is that only some of the heat-clearing and oil-controlling herbal components are retained, specifically 20 parts of Prunella vulgaris, 12 parts of Lonicera japonica, 10 parts of Chrysanthemum morifolium, and 10 parts of Morus alba leaves. Cassia tora, Celosia argentea, Mentha haplocalyx, Cicadae periostracum, Buddleja officinalis, and Salvia miltiorrhiza are not added. The composition and amount of the skin-care excipient powder are the same as in Example 2. Other preparation steps are the same as in Example 2.

[0035] Comparative Example 2: This comparative example is used to verify the effects of ultrafine grinding and skin care excipients on product performance.

[0036] The difference between this comparative example and Example 2 is that the types and amounts of herbal raw materials are the same as in Example 2, but no skin-care excipient powder is added; at the same time, low-temperature airflow ultrafine grinding is not performed, but only ordinary universal pulverizer is used for grinding and sieving, and the particle size D90 of the resulting herbal powder is about 350 μm. Other steps are the same as in Example 2.

[0037] Comparative Example 3: This comparative example is used to simulate conventional oil-control mud film powder.

[0038] This comparative example consists of 60 parts kaolin, 30 parts rice starch, 5 parts honeysuckle powder, and 5 parts chrysanthemum powder. It does not include prunella vulgaris, cassia seed, celosia seed, mulberry leaf, mint, cicada molting, buddleja officinalis, or salvia miltiorrhiza, nor does it prepare composite modified plant polysaccharide microgel powder or modified mineral adsorbent powder. After ordinary mixing, sterilization, and packaging, a conventional oil-control mud film powder is obtained.

[0039] Efficacy Verification Trial: Subjects with oily, combination, and easily reddened skin, exhibiting mild to moderate acne, were randomly divided into six groups: Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, and Comparative Example 3, with 20 subjects in each group. All groups used the corresponding sample in the same manner, applying it topically three times a week for 15 minutes each time, for four consecutive weeks. Before and after the test, subjects were placed in a constant temperature and humidity environment. Changes in sebum content were measured using a skin oil analyzer, changes in erythema and melanin indices were measured using a skin erythema and melanin analyzer, and changes in transepidermal water loss (TEWL) were measured using a transepidermal water loss analyzer. Acne appearance count, dryness / itching discomfort, and comfort were recorded using the same evaluation criteria.

[0040] The minimum performance standards were set as follows: sebum content reduction rate of no less than 20%, erythema index reduction rate of no less than 14%, acne appearance count reduction rate of no less than 18%, dryness and itching discomfort reduction rate of no less than 20%, melanin index reduction rate of no less than 8%, TEWL improvement rate of positive value, and user comfort score of no less than 7 points. The test results are shown in Table 1.

[0041] Table 1 shows the performance test results of each embodiment and comparative example; As shown in Table 1, Examples 1 to 3 all meet the preset minimum performance standards, and their overall comprehensive indicators are superior to those of Comparative Examples 1 to 3. This indicates that within the scope of composition, ratio, particle size, water content, and preparation process defined in the claims, the obtained herbal skincare mask powder can achieve good non-therapeutic skincare effects. Example 1 is at the left end of the scope of the claims, and its herbal components and skincare excipients are used in relatively low amounts. Although its effects are lower than those of Example 2, it can still achieve basic properties such as sebum regulation, soothing redness, improving the appearance of acne, improving dryness and itching, and improving the appearance of post-acne dullness. This indicates that the low-dosage end is still feasible.

[0042] Example 2 is optimal, with a relatively balanced proportion among the herbal components. The components for clearing liver stagnation and resolving nodules, dispelling wind and clearing heat, dispelling wind and moisturizing, and promoting blood circulation and regulating skin exhibit good synergistic effects. Simultaneously, the proportions of the composite modified plant polysaccharide microgel powder, modified mineral adsorbent powder, starch excipients, and moisturizing protectants are moderate, which helps improve the powder's dispersibility, adherence, and moisturizing comfort while maintaining a refreshing skin feel. Therefore, Example 2 demonstrates superior performance in terms of sebum content reduction rate, erythema index reduction rate, acne appearance count reduction rate, dryness and itching discomfort reduction rate, melanin index reduction rate, TEWL improvement rate, and user comfort.

[0043] Example 3, located at the right-hand end of the claims, uses a higher amount of herbal components and skin-care excipients, yet still achieves a significantly better overall skincare effect than the comparative example. However, due to the high amounts of herbal components, plant polysaccharide microgel powder, and modified mineral adsorbent powder, and the fact that the powder particle size is close to the upper limit of the range, the blended system may experience increased viscosity, increased spreading resistance, enhanced film-like feel, or decreased refreshing feel. Simultaneously, the higher drying temperature may result in a slightly lower retention rate of some heat-sensitive herbal characteristic components compared to the preferred process. Therefore, the overall effect of Example 3 is lower than that of Example 2, but it still meets the minimum performance standard, indicating that the right-hand end range can still achieve the technical objective of this invention.

[0044] Comparative Example 1 only retains some heat-clearing and oil-controlling herbs, lacking cassia seed, celosia seed, peppermint, cicada slough, buddleja flower, and salvia miltiorrhiza. This results in it lacking a complete formula for clearing liver stagnation, dispelling wind and heat, moisturizing and protecting, and promoting blood circulation and skin conditioning. Therefore, although Comparative Example 1 has a certain improvement effect on sebum appearance, its improvement in erythema index, dryness and itching discomfort, acne appearance count, and melanin index is lower than that of Example 2. This indicates that the ten-herb compound formula of the present invention is an important factor in improving the overall skin care effect.

[0045] Although Comparative Example 2 used the same ten-herb formula as Example 2, it did not include skin-care excipient powders and did not undergo ultra-fine grinding. This resulted in larger powder particle size, poor dispersibility, and insufficient uniformity after mixing, making it more prone to causing a grainy feel and poor skin adhesion during external application. Therefore, the user comfort and TEWL improvement rate of Comparative Example 2 were significantly lower than those of Example 2, and other appearance improvement indicators also decreased accordingly. This indicates that powder refinement and excipient structures such as composite modified plant polysaccharide microgel powder and modified mineral adsorbent powder play an important role in improving the product's external application performance.

[0046] Comparative Example 3 is a conventional oil-control mud mask powder, which mainly relies on mineral powders such as kaolin for oil adsorption. It lacks the ten-herb compound formulation described in this invention, and does not utilize composite modified plant polysaccharide microgel powder or modified mineral adsorption powder. Although this group has a certain sebum adsorption capacity, its improvement in erythema index, dryness and itching discomfort, acne appearance count, and melanin index is relatively low, and its TEWL improvement rate is negative, indicating that conventional strong adsorption mud mask powders may cause a certain degree of dryness or decreased barrier comfort after use. In contrast, this invention, through herbal compound formulation, powder refinement, and skin-shaping powder compounding, enables the product to have better overall performance in terms of oil control, soothing, moisturizing, skin adherence, and user comfort.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
