Description

Cosmetic composition for generating microelectrical stimulation, cosmetic kit, and skin care method using the same

[0001] The present invention relates to a cosmetic composition for generating microelectrical stimulation, a cosmetic kit, and a skin care method using the same, and more particularly, to a cosmetic composition for generating microelectrical stimulation using alternating current energy generated in the human body, and a skin care method using the same.

[0002] Microcurrent refers to a very weak electrical current that most closely resembles the bioelectric current flowing through the human body. Applying microelectric stimulation with a similar intensity (e.g., current of approximately 1,000 μA or less) has been proven to improve wrinkles, promote wound and fracture healing, alleviate muscle fatigue, alleviate inflammation, improve blood circulation, and reduce abdominal fat.

[0003] Accordingly, the cosmetics industry is developing devices and apparatus that can separately supply microcurrents to the skin to further improve skin condition, and the fields and methods of their application are becoming increasingly diverse. Consequently, various beauty devices that apply microelectrical stimulation to the skin have gained popularity in recent years. However, these beauty devices have drawbacks such as high prices, the need to charge them with external electrical energy, the time required to treat the skin, and their inconvenient portability. Furthermore, if designed for voltages exceeding 40 V, these beauty devices can cause side effects such as pain and skin necrosis with prolonged use.

[0004] Accordingly, research is being conducted to apply the concept of piezoelectricity, a phenomenon in which microcurrents or voltages are generated by polarization when force is applied to cosmetics based on the method of applying the product to the skin and then patting or applying pressure and rubbing it into the skin, as a product that can provide microelectrical stimulation without an external power supply. However, even in these cases, the act of applying pressure to the skin must still be performed directly by a person, which can cause unnecessary irritation due to rubbing or applying pressure. In addition, since the amount and movement of pressure vary depending on the person performing the action, it is difficult to achieve consistent effects.

[0005] Therefore, it is necessary to develop a cosmetic that can increase the absorption rate of the cosmetic and produce effects such as wrinkle improvement, skin tone correction, and whitening by generating micro-electrical stimulation simply by applying it without the need for external electricity supply or the user's rubbing or applying pressure.

[0006] The purpose of the present invention is to solve the above-mentioned problems, and to provide a cosmetic composition for generating micro-electric stimulation having a strength similar to bioelectricity without requiring a separate power source by utilizing AC electric potential generated in the human body due to physical activity such as walking, and a skin care method using the same, which can exhibit functions such as improving the absorption rate of applied cosmetics, improving skin elasticity, alleviating wrinkles, correcting skin tone, and whitening simply by applying the cosmetics to the skin without rubbing or applying pressure.

[0086] FIG. 1 is a schematic perspective view showing the structure of a cosmetic composition for generating microelectric stimulation of the present invention applied to the skin, and FIG. 2 is a perspective view showing the schematic structure of microelectric field inducing particles (110, 210) included in the cosmetic composition for generating microelectric stimulation of the present invention.

[0087] Hereinafter, the cosmetic composition for generating microelectric stimulation of the present invention will be described with reference to FIGS. 1 and 2.

[0088]

[0089] First, a cosmetic composition according to the first embodiment (100) of the present invention will be described. Fig. 3 is a cross-sectional side view schematically showing the structure of a cosmetic composition according to the first embodiment (100) of the present invention when applied to the skin.

[0090] According to the first embodiment (100) of the present invention, the cosmetic composition for generating microelectric stimulation of the present invention is a cosmetic composition comprising a plurality of first microelectric field inducing particles (110) and a first skin-applicable cosmetic (120), wherein the first microelectric field inducing particles (110) include conductive core particles (112) and non-conductive shells (114), and the non-conductive shells (114) are coated on the surfaces of the conductive core particles (112), and a conductive core exposed portion (116) that is not partially coated can be formed.

[0091] In some cases, the first microelectric field inducing particle (110) may include only a conductive core particle (112) and exclude a non-conductive shell (114) (not shown). In such a case, the area exposed to the conductive core particle (112) is significantly wider than in the case of including a non-conductive shell (114), so the intensity of the electric field generation may be relatively weakened.

[0092] The first skin application cosmetic (120) is characterized by being a non-conductive material.

[0093] At this time, the non-conductive shell (114) may be coated as a layer that is very thin at the nanometer level, so that a partially uncoated portion may naturally occur, thereby forming a conductive core exposed portion (116), or the non-conductive shell (114) may be patterned to form coated and uncoated portions, or the coating layer may be unevenly coated by spraying a coating liquid that cannot coat the entire surface of the conductive core particle (112), thereby forming coated and uncoated portions naturally.

[0094] The first skin-applicable cosmetic (120) may additionally include a conductive material that volatilizes after skin application. The first skin-applicable cosmetic (120) can only implement the function of generating microelectrical stimulation if it is composed of a non-conductive material. However, if volatilization occurs immediately after skin application, it is acceptable as it does not affect the non-conductive properties.

[0095] The cosmetic composition for generating microelectrical stimulation of the present invention can generate microelectrical stimulation on the skin according to the following principle when applied to the skin.

[0096] Specifically, a plurality of first micro-electric field inducing particles (110) are uniformly distributed on the surface of the skin (130), and the conductive core particles (112) and the surface of the skin (130) are brought into contact through the conductive core exposed portion (116) of the non-conductive shell (114), and a contact electrode (A1) is formed at a portion of the conductive core particles (112) that is in contact with the skin (130) according to the contact, and a counter electrode (B1) is formed at another portion of the conductive core particles (112) that is not in contact with the skin (130), and a potential difference is generated between the portion of the skin that is in contact with the contact electrode (A1) and an adjacent portion of the skin that is not in contact, and a micro-electric stimulation can be generated on the skin due to the concentration of an electric field according to the potential difference.

[0097] At this time, in the conductive core particle (112), the contact electrode (A1) can be formed by transmitting an AC electric potential by dielectric polarization generated in the body, and the counter electrode (B1) acts as a free charge source (FCS) to supply free charges to the contact electrode (A1), so that the contact electrode (A1) and the counter electrode (B1) can have the same potential.

[0098] The above-mentioned AC potential can be generated by various physical activities, such as walking, changing clothes, using electronic devices, and contact with objects. Physical activity induces mechanical interactions between various materials, such as the sole of a shoe and the ground, or skin and clothing. These interactions can transfer charges from one surface to another through contact, separation, or friction. The surface charge density induces a specific electric potential in the contact layer of the material. Among physical activities, walking, in particular, can generate a relatively high electric potential due to the short contact time and large contact area. When a portion of the contact layer in contact with the ground is separated from the ground, the contact layer exhibits a specific electric potential that is transmitted in all directions toward surrounding materials, such as the body, air, the ground, walls, and furniture. On the other hand, when a portion of the contact layer remains attached to the ground, this potential is shielded by the induced charges of the ground. Consequently, a low-frequency AC potential is generated in the contact layer according to the walking cycle. This AC potential polarizes surrounding materials and dissipates into an AC electric field. In other words, the human body's physical activity repeatedly generates and dissipates AC energy. The present invention can utilize alternating current energy naturally generated by physical activity as a micro-electrical stimulation beneficial to the skin.

[0099] The conductive core particles (112) may be conductive metal microparticles such as gold (Au), platinum (Pt), silver (Ag), iron (Fe), and zinc (Zn); carbon-based microparticles such as carbon black, graphite, and graphene; and conductive polymer microparticles such as polyaniline, polypyrrole, and PEDOT:PSS (Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate). However, the scope of the present invention is not limited thereto, and various conductive materials that can be used as cosmetic ingredients may be applied.

[0100] The conductive core particles (112) are preferably spherical particles having an average diameter of 1 to 500 μm, more preferably 3 to 300 μm, and even more preferably 5 to 100 μm. If the average diameter is less than 1 μm, surface coating may be difficult or stable formation of the contact electrode (A1) and the counter electrode (B1) may be difficult, and if it exceeds 500 μm, physical stimulation may be caused when applied to the skin.

[0101] The non-conductive shell (114) may be a coating layer of silica, alumina, titania, PMMA (polymethyl methacrylate), PVP (polyvinylpyrrolidone), polyurethane, polyethylene, polysiloxane, polydimethylsiloxane, silsesquioxane, etc., but the scope of the present invention is not limited thereto, and various non-conductive coating materials that can be used as cosmetic ingredients may be used.

[0102] The non-conductive shell (114) is preferably formed as a coating layer having a thickness of 1 to 1000 nm, more preferably 5 to 800 nm, and even more preferably 10 to 500 nm. Forming a coating layer having a thickness of less than 1 nm may be difficult to process, and when it exceeds 1000 nm, unnecessary non-conductive shell material may be used.

[0103] The non-conductive shell (114) can be formed by applying various coating methods such as sol-gel method, chemical vapor deposition (CVD) method, sputtering, emulsion process for core-shell particle synthesis, plasma coating method, etc. using a precursor solution of a non-conductive shell material, and the coating method is not limited to the above methods.

[0104] For example, when performing silica coating, the precursor solution may be tetraethyl orthosilicate (TEOS) or silica sol.

[0105] The first skin application cosmetic (120) may have a dielectric constant of 1 to 1000, preferably 10 to 100, more preferably 20 to 50, and even more preferably 20 to 30.

[0106] Accordingly, an electric field of a certain strength can be formed on the skin.

[0107] The first skin application cosmetic (120) can adjust the ethanol component content to adjust the appropriate dielectric constant.

[0108] The first skin application cosmetic (120) may include one or more functional ingredients selected from moisturizing, wrinkle improvement, antioxidant, and whitening.

[0109] Specific functional materials included in the first skin application cosmetic (120) related to wrinkle improvement and elasticity improvement include peptide series such as Acetyl Hexapeptide-8, Palmitoyl Tripeptide-1, Palmitoyl Tripeptide-5, and Acetyl Tetrapeptide-5, and retinol, retinyl palmitate, hydrolyzed collagen, and hydrolyzed elastin, but the scope of the present invention is not limited thereto, and various other known wrinkle improvement and elasticity improvement ingredients may be applied.

[0110] In addition, moisturizing functional ingredients include glycerin, butylene glycol, propanediol, pentylene glycol, sodium hyaluronate, β-glucan, ceramide NP, ceramide NG, ceramide AP, sodium PCA, sodium lactate, arginine, etc., but the scope of the present invention is not limited thereto, and various other known moisturizing ingredients may be applied.

[0111] In addition, antioxidant functional ingredients may include vitamin C derivatives (ascorbyl glucoside, magnesium ascorbyl phosphate, 3-O-ethyl ascorbic acid, etc.), vitamin E (tocopherol, tocopheryl acetate), polyphenols (green tea extract, grape seed extract, rosemary extract, etc.), resveratrol, coenzyme Q10 (ubiquinone), etc., but the scope of the present invention is not limited thereto, and various other known antioxidant functional ingredients may be applied.

[0112] In addition, the first microelectric field inducing particle (110) can promote skin absorption of the above skin application cosmetic (120) and exhibit a wrinkle improvement function according to microelectric stimulation.

[0113] The first microelectric field inducing particle (110) and the first skin application cosmetic (120) can be mixed and packaged in one container.

[0114]

[0115] Next, a cosmetic composition according to the second embodiment (200) of the present invention will be described. Fig. 4 is a cross-sectional side view schematically showing the structure of a cosmetic composition according to the second embodiment (200) of the present invention when applied to the skin.

[0116] According to a second embodiment (200) of the present invention, a cosmetic composition for generating microelectric stimulation of the present invention is a cosmetic composition comprising a plurality of second microelectric field inducing particles (210) and a second skin-applicable cosmetic (220), wherein the second microelectric field inducing particles (210) include non-conductive core particles (212) and conductive shells (214), the conductive shells (214) are coated on the surfaces of the non-conductive core particles (212), and the second skin-applicable cosmetic (220) is characterized in that it is a non-conductive material.

[0117] The conductive shell (214) may be formed with a non-conductive core exposed portion (216) that is partially uncoated on the non-conductive core particle (212).

[0118] The conductive shell (214) may be coated in a very thin layer at the nanometer level, so that a partially uncoated portion may naturally occur, thereby forming a non-conductive core exposed portion (216), or the conductive shell (214) may be patterned to form coated and uncoated portions, or the coating layer may be unevenly coated by spraying a coating liquid that cannot coat the entire surface of the non-conductive core particle (212), thereby forming coated and uncoated portions naturally.

[0119] The second skin-applicable cosmetic (220) may additionally include a conductive material that volatilizes after skin application. The second skin-applicable cosmetic (220) can only implement the function of generating microelectrical stimulation if it is composed of a non-conductive material. However, if volatilization occurs immediately after skin application, it is acceptable as it does not affect the non-conductive properties.

[0120] The cosmetic composition for generating microelectric stimulation according to the second embodiment of the present invention can generate microelectric stimulation on the skin according to the following principle when applied to the skin.

[0121] Specifically, a plurality of second micro-electric field inducing particles (210) are distributed on the surface of the skin (130), a conductive shell (214) is brought into contact with the surface of the skin (230), a contact electrode (A2) is formed at a portion of the conductive shell (214) that is in contact with the skin (130) according to the contact, and a counter electrode (B2) is formed at another portion of the conductive shell (214) that is not in contact with the skin (130), a potential difference is generated between the portion of the skin that is in contact with the contact electrode (A1) and an adjacent portion of the skin that is not in contact, and micro-electric stimulation can be generated on the skin due to the concentration of an electric field according to the potential difference.

[0122] At this time, in the conductive shell (214), the contact electrode (A2) is formed by transmitting an AC electric potential by dielectric polarization generated in the body, and the counter electrode (B2) supplies free charges to the contact electrode (A2) as a free charge source (FCS), so that the contact electrode (A2) and the counter electrode (B2) can have the same potential.

[0123] The above AC potential can be generated by any one physical activity selected from walking, changing clothes, using electronic devices, and contact with objects.

[0124] The non-conductive core particles (212) may be silica, alumina, titania, mica, synthetic fluorophlogopite, polypropylene, nylon, PMMA (polymethyl methacrylate), polyurethane, etc., but the present invention is not limited thereto and all non-conductive fine particles that can be used in cosmetics can be applied.

[0125] The non-conductive core particles (212) are preferably spherical particles having an average diameter of 1 to 500 μm, more preferably 3 to 300 μm, and even more preferably 5 to 100 μm. If the average diameter is less than 1 μm, it may be difficult to coat the surface, making it difficult to stably form the contact electrode (A2) and the counter electrode (B2), and if it exceeds 500 μm, it may cause physical irritation when applied to the skin.

[0126] The conductive shell (214) may be a coating layer of gold (Au), platinum (Pt), silver (Ag), iron (Fe), zinc (Zn), carbon nanotubes, graphite, carbon black, graphene, polyaniline, polypyrrole, PEDOT:PSS (Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate), etc., but the scope of the present invention is not limited thereto, and various conductive coating materials that can be used as cosmetic ingredients may be used.

[0127] The conductive shell (214) is preferably formed as a coating layer having a thickness of 1 to 1000 nm, more preferably 5 to 800 nm, and even more preferably 10 to 500 nm. Forming a coating layer having a thickness of less than 1 nm may be difficult to process, and when it exceeds 1000 nm, unnecessary conductive shell material may be used.

[0128] The conductive shell (214) can be formed using a metal such as gold (Au), silver (Ag), copper (Cu), aluminum (Al), a metal oxide (e.g., indium tin oxide (ITO), fluorine-doped tin oxide (FTO)), carbon nanotubes, graphene, a conductive polymer (e.g., polyaniline, polypyrrole), or a similar conductive material or precursor thereof.

[0129] The coating method of the conductive shell (214) may be chemical vapor deposition (CVD), physical vapor deposition (PVD), sputtering, sol-gel process, emulsion process, electrochemical plating, chemical plating, plasma coating, etc., and the scope of the present invention is not limited thereto and various coating methods may be applied.

[0130] The second skin application cosmetic (220) may have a dielectric constant of 1 to 1000, preferably 10 to 100, more preferably 30 to 50, and even more preferably 30 to 40. When it has such a dielectric constant, it is possible to improve electric field concentration on the skin.

[0131] Accordingly, an electric field of a certain size can be formed on the skin.

[0132] The second skin application cosmetic (220) can control the content of moisture, glycerin, and glycol to control the dielectric constant.

[0133] In addition, the second microelectric field inducing particle (210) can promote skin absorption of the second skin application cosmetic (220) and exhibit a wrinkle improvement function according to microelectric stimulation.

[0134] The second microelectric field inducing particle (210) and the second skin application cosmetic (220) can be mixed and packaged in one container.

[0135]

[0136] According to a third embodiment of the present invention, a cosmetic composition comprising a plurality of first microelectric field inducing particles (110), a plurality of second microelectric field inducing particles (210), and a cosmetic for skin application, wherein the first microelectric field inducing particles (110) include conductive core particles (112) and non-conductive shells (114), the non-conductive shells (114) are coated on the surface of the conductive core particles (112), and a conductive core exposed portion (116) that is not partially coated is formed, the second microelectric field inducing particles (210) include non-conductive core particles (212) and conductive shells (214), the conductive shells (214) are coated on the surface of the non-conductive core particles (212), and the cosmetic for skin application (120) is characterized in that it is a non-conductive material.

[0137] At this time, the description of the first microelectric field inducing particle (110) and the second microelectric field inducing particle (210) is the same as that described in the first and second implementation examples.

[0138] Here, a plurality of first microelectric field inducing particles (110), a plurality of second microelectric field inducing particles (210) and a cosmetic for skin application can be mixed into one container.

[0139]

[0141]

[0142] According to a fifth embodiment of the present invention, a skin beauty method using the cosmetic composition for generating microelectric stimulation is provided.

[0143] The skin beauty method of the present invention generates micro-electrical stimulation simply by applying the cosmetic composition for generating micro-electrical stimulation to the skin, thereby improving the skin absorption rate of the cosmetic composition and enhancing the effects of wrinkle improvement, skin whitening, and skin tone correction.

[0144] That is, micro-electrical stimulation can be generated without any separate rubbing or pressure action.

[0145]

[0146] FIG. 9 is a schematic diagram showing the configuration of a cosmetic kit for generating microelectric stimulation according to the sixth embodiment (600) of the present invention, FIG. 10 is a schematic diagram showing the laminated form of a first cosmetic application layer (12) and a second cosmetic application layer (22) immediately after applying a first cosmetic (10) and a second cosmetic (20) included in a cosmetic kit for generating microelectric stimulation according to the seventh embodiment (700) of the present invention to the skin, and FIG. 11 is a schematic diagram showing the laminated form of a first cosmetic application layer (12) and a second cosmetic application layer (22) after applying a first cosmetic (10) and a second cosmetic (20) included in a cosmetic kit for generating microelectric stimulation according to the seventh embodiment (700) of the present invention to the skin and after a predetermined period of time has elapsed.

[0147] Hereinafter, a cosmetic kit for generating micro-electric stimulation according to the sixth embodiment (600) and the seventh embodiment (700) of the present invention will be described with reference to FIGS. 9 to 11.

[0148] A cosmetic kit for generating micro-electric stimulation according to the sixth embodiment (600) of the present invention is characterized by including a first cosmetic (10) including a non-conductive cosmetic; and a second cosmetic (20) including a conductive cosmetic.

[0149] At this time, the first cosmetic (10) is separately packaged in a first container (1), and the second cosmetic (20) is separately packaged in a second container (2), and is characterized in that it is used for the purpose of first applying the first cosmetic (10) to the surface of the skin (40), and then second applying the second cosmetic (2).

[0150] According to the seventh embodiment (700) of the present invention, a first cosmetic application layer (12) can be formed on the surface of the skin (40) through first application and second application; and a second cosmetic application layer (22) can be formed on the first cosmetic application layer (12).

[0151] The first cosmetic composition (10) may additionally include a conductive material that volatilizes after application to the skin. The first cosmetic composition (10) can only implement the function of generating microelectrical stimulation if it is composed of a non-conductive material. However, if volatilization occurs immediately after application to the skin, it is acceptable as it does not affect the non-conductive properties.

[0152] The first cosmetic application layer (12) may have a skin exposure portion (30) formed in part as a gap where the skin surface (40) is exposed.

[0153] At this time, the skin exposure portion (30) may be formed by evaporation of at least one selected from among the conductive material, water, and ethanol included in the first cosmetic application layer (12), or may be formed by incomplete application of the first cosmetic application layer (12) on the skin (40).

[0154] The skin exposure portion (30) may include one or more pores, and preferably, the plurality of pores are uniformly distributed to evenly generate a micro-electric field on the skin.

[0155] When the first cosmetic (10) and the second cosmetic included in the cosmetic kit for generating micro-electrical stimulation of the present invention are applied to the skin, micro-electrical stimulation can be generated on the skin according to the following principle.

[0156] Specifically, a part of the second cosmetic application layer (22) penetrates through the skin exposure area (30) to form a second cosmetic penetration layer (24) that is in direct contact with the skin (40) surface.

[0157] A contact electrode (A) is formed at a site where the second cosmetic penetration layer (24) is in contact with the surface of the skin (40), and a counter electrode (B) is formed at another site that is not in contact with the surface of the skin (40) as it approaches the contact electrode (A), and a potential difference is generated between the skin site in contact with the contact electrode (A) and the adjacent site of the skin that is not in contact, and micro-electrical stimulation can be generated on the skin due to the concentration of an electric field according to the potential difference.

[0158] At this time, the contact electrode (A) is formed by transmitting AC electric potential due to dielectric polarization generated in the body, and the counter electrode (B) is characterized in that it supplies free charge to the contact electrode (A) as a free charge source (FCS), so that the contact electrode and the counter electrode have the same potential.

[0159] The above-mentioned AC potential can be generated by various physical activities, such as walking, changing clothes, using electronic devices, and contact with objects. Physical activity induces mechanical interactions between various materials, such as the sole of a shoe and the ground, or skin and clothing. These interactions can transfer charges from one surface to another through contact, separation, or friction. The surface charge density induces a specific electric potential in the contact layer of the material. Among physical activities, walking, in particular, can generate a relatively high electric potential due to the short contact time and large contact area. When a portion of the contact layer in contact with the ground is separated from the ground, the contact layer exhibits a specific electric potential that is transmitted in all directions toward surrounding materials, such as the body, air, the ground, walls, and furniture. On the other hand, when a portion of the contact layer remains attached to the ground, this potential is shielded by the induced charges of the ground. Consequently, a low-frequency AC potential is generated in the contact layer according to the walking cycle. This AC potential polarizes surrounding materials and dissipates into an AC electric field. In other words, the human body's physical activity repeatedly generates and dissipates AC energy. The present invention can utilize alternating current energy naturally generated by physical activity as a micro-electrical stimulation beneficial to the skin.

[0160] The first cosmetic (10) including a non-conductive cosmetic may have a dielectric constant of 1 to 1000, preferably 10 to 100, more preferably 20 to 50, and even more preferably 20 to 30.

[0161] Accordingly, an electric field of a certain strength can be formed on the skin.

[0162] The first cosmetic (10) including a non-conductive cosmetic can adjust the ethanol component content to adjust the appropriate dielectric constant.

[0163] The first cosmetic (10) may include one or more functional ingredients selected from moisturizing, wrinkle improvement, antioxidant, and whitening.

[0164] Specific functional materials included in the first cosmetic (10) and related to wrinkle improvement and elasticity improvement include peptide series such as Acetyl Hexapeptide-8, Palmitoyl Tripeptide-1, Palmitoyl Tripeptide-5, and Acetyl Tetrapeptide-5, and retinol, retinyl palmitate, hydrolyzed collagen, and hydrolyzed elastin, but the scope of the present invention is not limited thereto, and various other known wrinkle improvement and elasticity improvement ingredients may be applied.

[0165] In addition, moisturizing functional ingredients include glycerin, butylene glycol, propanediol, pentylene glycol, sodium hyaluronate, β-glucan, ceramide NP, ceramide NG, ceramide AP, sodium PCA, sodium lactate, arginine, etc., but the scope of the present invention is not limited thereto, and various other known moisturizing ingredients may be applied.

[0166] In addition, antioxidant functional ingredients may include vitamin C derivatives (ascorbyl glucoside, magnesium ascorbyl phosphate, 3-O-ethyl ascorbic acid, etc.), vitamin E (tocopherol, tocopheryl acetate), polyphenols (green tea extract, grape seed extract, rosemary extract, etc.), resveratrol, coenzyme Q10 (ubiquinone), etc., but the scope of the present invention is not limited thereto, and various other known antioxidant functional ingredients may be applied.

[0167] The conductive cosmetic included in the second cosmetic (20) may include conductive metal ultrafine particles such as gold (Au), platinum (Pt), silver (Ag), iron (Fe), and zinc (Zn), ultrafine particles of metal oxides (e.g., indium tin oxide (ITO), fluorine-doped tin oxide (FTO)), carbon-based ultrafine particles such as carbon black, graphite, and graphene, and conductive polymer ultrafine particles such as polyaniline, polypyrrole, and PEDOT:PSS (Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate), but the scope of the present invention is not limited thereto, and various conductive materials that can be used as cosmetic ingredients may be applied.

[0168] The conductive ultrafine particles included in the conductive cosmetic may have an average diameter of 1 to 1000 nm, preferably 1 to 100 nm.

[0169] The conductive ultrafine particles are preferably included in the second cosmetic composition in an amount ranging from 0.1 to 10 wt%. If included in an amount less than 0.1 wt%, the electrical conductivity may be low, and thus micro-electrical stimulation may not sufficiently occur. If included in an amount exceeding 10 wt%, the effect of micro-electrical stimulation on the skin may be minimal, but the use of unnecessary conductive materials may increase costs or cause skin irritation.

[0170] At this time, it is preferable that the electrical conductivity of the second cosmetic composition be formed to be 50 to 100 μs / cm. When the electrical conductivity is in this range, it is most advantageous for forming skin micro-stimulation and can maximize the absorption rate of the first cosmetic composition.

[0171] The second cosmetic (20) including the conductive cosmetic can maximize the functionality according to the ingredients of the first cosmetic (10) by promoting skin absorption of the first cosmetic (10) including the non-conductive cosmetic, and can be used for one or more purposes selected from wrinkle improvement and skin tone correction by forming a skin micro-electric field itself.

[0172] In addition to the conductive ultrafine particles, the second cosmetic composition may include various ingredients that can be generally included in cosmetics. Specifically, purified water, glycerin, propanediol, etc. may be used as water-phase ingredients, stearate, steric acid, carbomer, triethanolamine, etc. may be used as emulsifiers and stabilizers, pH adjusters, etc., and mineral oil, vegetable oils such as jojoba oil or argan oil, and other preservatives or fragrances may be used as oil-phase ingredients.

[0173] The first cosmetic and the second cosmetic may each independently be in any one formulation selected from among lotion, liquid, cream, and gel.

[0174]

[0175] According to the seventh embodiment (700) of the present invention, a skin beauty method using the cosmetic kit for generating micro-electric stimulation is provided.

[0176] Specifically, first, a first cosmetic (10) is applied to form a first cosmetic application layer (12), and after leaving it for a predetermined period of time so that the conductive material, moisture, ethanol, etc. included in the first cosmetic application layer evaporates, a second cosmetic (20) is applied thereon to form a second cosmetic application layer (22). At this time, the time for leaving it after applying the first cosmetic (10) may vary depending on the cosmetic formulation, the time for the conductive material, moisture and ethanol components to evaporate, the applied thickness, etc.

[0177] At this time, the first cosmetic application layer (12) according to the application of the first cosmetic (10) is preferably formed to a thickness of 1 to 1000 ㎛, and more preferably, it can be applied to a thickness of 10 to 100 ㎛. If it is applied to a thickness of less than 1 ㎛, the components of the first cosmetic (10) may be included too little per unit surface area, which may reduce absorption of the functional ingredients, and if it exceeds 1000 ㎛, not only may the first cosmetic (10) not be absorbed and be wasted, but also the second cosmetic penetration layer (24) may not be sufficiently generated, which may reduce the degree of skin microelectric field generation.

[0178] Meanwhile, the second cosmetic application layer (22) according to the application of the second cosmetic (20) is preferably formed to a thickness of 1 to 1000 ㎛, and more preferably, it can be applied to a thickness of 10 to 100 ㎛. If it is applied to a thickness of less than 1 ㎛, the second cosmetic (20) may not sufficiently penetrate into the pores formed in the first cosmetic application layer (10), and thus the second cosmetic penetration layer (24) may be incompletely formed, thereby reducing the formation of a skin microelectric field. If it is applied to a thickness exceeding 1000 ㎛, an unnecessary amount of the second cosmetic (20) may be used, which may be a burden to the skin.

[0179] The skin beauty method according to the seventh embodiment (700) of the present invention can improve the skin absorption rate of the cosmetic by generating micro-electrical stimulation by only applying the cosmetic for generating micro-electrical stimulation to the skin in two steps, and can improve the effects of wrinkle improvement, skin whitening, skin tone correction, etc. by improving the absorption rate of the functional ingredient of the micro-electrical stimulation itself or the first cosmetic (10).

[0180] That is, it has the advantage of being able to generate micro-electrical stimulation without having to perform a separate rubbing or applying pressure.

[0262] Skin care was performed under the same conditions as Example 1, except that in the second application, a non-conductive cosmetic packaged in the first container was applied instead of a conductive cosmetic packaged in the second container.

[0263] A schematic diagram of the form of applying cosmetics on the skin surface according to the skin care method of Comparative Example 2 is shown in Figure 12.

[0264]

[0265] Comparative Example 3: Skin beauty by applying non-conductive cosmetics to conductive cosmetics

[0266] Skin care was performed under the same conditions as Example 1, except that the second application was performed immediately without waiting 3 minutes after the first application. Accordingly, water, ethanol, etc. did not evaporate from the first non-conductive cosmetic layer, preventing the formation of pores.

[0267] A schematic diagram of the form of applying cosmetics on the skin surface according to the skin care method of Comparative Example 3 is shown in Figure 13.

[0268]

[0269] Comparative Example 4: Skin beauty by applying conductive cosmetics to non-conductive cosmetics

[0270] Skin care was performed under the same conditions as Example 1, except that after the first application using the conductive cosmetic in the second container, the second application was immediately performed using the non-conductive cosmetic in the first container.

[0271] A schematic diagram of the form of applying cosmetics on the skin surface according to the skin care method of Comparative Example 4 is shown in Figure 14.

[0272]

[0273] Comparative Example 5: Skin beauty by applying conductive cosmetics to non-conductive cosmetics

[0274] Skin care was performed under the same conditions as Example 1, except that the conductive cosmetic from the second container was used in the first application and the non-conductive cosmetic from the first container was used in the second application.

[0275] A schematic diagram of the form of applying a cosmetic on the skin surface according to the skin care method of Comparative Example 5 is shown in Fig. 15. According to this, some of the components in the conductive second cosmetic application layer (22) may evaporate or pores may be formed due to incomplete application, and some of the non-conductive cosmetic of the non-conductive first cosmetic application layer (12) may penetrate into the pores, thereby forming a first cosmetic penetration layer (14).

[0276]

[0277] Experimental Example 1: Confirmation of Skin Electric Field Formation According to Skin Beauty Method

[0278] In order to confirm the generation of skin micro-electric fields according to the skin beauty methods performed in Example 2 and Comparative Examples 2 to 5, a simulation experiment was performed using COMSOL Multiphysics, and the results are shown in Fig. 16.

[0279] Accordingly, it can be confirmed that a micro-electric field is well formed on the skin when a non-conductive cosmetic is first applied according to Example 2, and then a conductive cosmetic is applied after waiting for pores to form. Specifically, the simulation experiment results of Example 2 show various combinations of the distribution states of the non-conductive cosmetic application layer and the conductive cosmetic application layer depending on the cosmetic application state. It can be confirmed that a micro-electric field is well formed deep in the skin in all combinations of Example 2.

[0280] In contrast, in Comparative Example 2, only a non-conductive cosmetic was applied, so no electric field was formed at all, and in Comparative Example 3, even though the application was performed in the order of non-conductive cosmetic -> conductive cosmetic, the conductive cosmetic layer was formed before a gap was created in the non-conductive cosmetic layer, so the skin surface and the conductive cosmetic layer did not come into direct contact, and thus no electric field was formed on the skin. In addition, in Comparative Example 4, the application was performed in the order of conductive cosmetic -> non-conductive cosmetic, so that the conductive cosmetic and the skin came into contact and an electric field was generated, but there was a problem that it was difficult for the non-conductive cosmetic to be absorbed.
