Description

Technology Field

[0001] The present invention relates to a skin care technology, and more specifically, to a skin condition-based selective complex skin care method and skin care device capable of improving the appearance of the skin by including a complex skin care process based on the condition of the skin, comprising exfoliation of the skin, delivery of active ingredients through micro-stimulation, and light energy irradiation or antibacterial treatment, and by selectively combining and applying various skin treatment modules for improving skin elasticity, alleviating skin troubles, and improving skin tone. Background Technology

[0002] The appearance of the skin is closely related to an individual's aesthetic satisfaction, and skin elasticity, texture, tone, and overall condition can be altered by various internal and external factors. Generally, the skin may exhibit a complex combination of phenomena such as decreased elasticity, skin problems, pigmentation, and uneven skin tone due to various factors including aging, UV exposure, environmental pollution, hormonal changes, and lifestyle habits.

[0003] Conventionally, to improve skin condition, techniques such as massage or physical stimulation to improve skin elasticity, antimicrobial treatment to regulate the microbial environment on the skin surface, and light energy irradiation to improve skin tone have been developed and applied individually. In addition, the application of cosmetics to deliver active ingredients to the skin and absorption-promoting techniques using micro-stimulation are also widely used.

[0004] However, conventional skincare technologies are often structured around single functions limited to specific purposes, which presents limitations in flexibly responding to real-world situations where various skin conditions occur in combination. For instance, treatments for improving skin elasticity, alleviating skin troubles, and correcting pigmentation are frequently performed separately, making it difficult to provide integrated care that comprehensively considers multiple skin conditions. Consequently, methods that combine individual processes based on the experience of the user or manager are predominantly used.

[0005] Therefore, there is a need for a new type of skin care method capable of selectively applying multiple skin treatment technologies by comprehensively considering various skin conditions, and for a device capable of implementing this. The problem to be solved

[0006] The technical problem to be solved by the skin care method and skin care device according to the technical concept of the present invention is to provide a skin care method and skin care device capable of selectively applying a plurality of skin treatment modules according to the skin condition in order to respond to various skin conditions that appear in combination, such as decreased skin elasticity, skin troubles, and pigmentation.

[0007] Furthermore, the technical problem that the skin care method and skin care device according to the technical concept of the present invention aim to achieve is to provide a skin care method and skin care device that enable customized care suitable for the skin condition by analyzing the skin condition, such as the state of keratinization, moisture state, and response to irritation, and determining whether to apply a skin treatment module based on the analysis results.

[0008] In addition, the technical problem that the skin care method and skin care device according to the technical concept of the present invention aim to achieve is to provide a skin care method and skin care device that enable more precise and consistent skin care by ensuring that a plurality of skin treatment modules are not performed independently of each other, but rather that the intensity, depth, and execution order of stimulation applied to the skin are interconnected, and that the execution conditions of each treatment step can be dynamically adjusted based on the skin reaction state.

[0009] Furthermore, the technical objective of the skin care method and skin care device according to the technical concept of the present invention is to provide a complex skin care technology that can improve the penetration efficiency of active ingredients by utilizing delivery pathways within the skin formed by micro-stimulation, and efficiently induce pigment alleviation and skin tone improvement effects through light energy irradiation.

[0011] A skin care method according to one embodiment of the technical concept of the present invention, in a skin care method for improving the appearance of the skin, comprises: a step of cleansing the surface of the skin; a pretreatment step of organizing the stratum corneum of the skin to form an environment for the absorption of an active ingredient; a step of applying micro-stimulation to the skin to promote the delivery of an active ingredient into the skin; and a step of applying a skin treatment module according to the skin condition, wherein the skin treatment module may include at least one of a lifting module for improving skin elasticity, a skin condition stabilization module for alleviating skin troubles, and a pigmentation alleviation module for improving skin tone.

[0012] The step of applying the above skin treatment module includes: a step of analyzing the skin condition; and a step of selecting at least one of a lifting module, a skin condition stabilization module, and a pigment reduction module based on the analysis results.

[0013] The lifting module comprises the step of spreading stimulation from the center of the skin outward; and the step of moving the skin upward or inward.

[0014] The skin condition stabilization module includes a step of controlling the microbial environment on the skin surface using plasma or active species.

[0015] Active species include nitrogen oxides (NO), hydroxyl radicals (OH), reactive oxygen species (ROS), and nitrogen-derived compounds.

[0016] The pigment reduction module described above includes a step of micronizing pigment particles within the skin by irradiating light energy.

[0017] The above-mentioned micronized pigment particles are induced to be removed by internal circulation or lymphatic flow.

[0018] The above micro-stimulation is applied by forming micro-channels in the skin using micro-needles, rolling devices, or micro-vibrations.

[0019] The active ingredient includes at least one of hyaluronic acid, collagen, peptide, plant-derived extract, and panthenol.

[0020] The above skin treatment module is synchronized to synchronize the intensity, execution sequence, and operation time of stimulation or treatment applied to the skin, and the synchronization control adjusts the conditions for performing light energy irradiation or antibacterial treatment in real time based on the skin response state formed by micro-stimulation.

[0021] The above skin response state includes the recovery rate after skin stimulation, the amount of moisture change, or the change in surface impedance, and the above performance conditions are set to change non-linearly according to the skin response state.

[0022] Micro-stimulation, antimicrobial treatment, and light energy irradiation are repeated on the same site with different time delays, and the interval for repetition is set based on the point at which the skin's temporary response decreases.

[0023] Multiple active ingredients having different viscosities are sequentially supplied into the skin through microchannels formed by micro-stimulation, and the multiple active ingredients are configured such that the low-viscosity ingredient is supplied first and the high-viscosity ingredient is supplied subsequently, thereby differentiating the penetration depth into the skin.

[0024] Light energy irradiation interacts with a light-absorbing substance applied to the surface of the skin to induce a localized thermal reaction, and said thermal reaction is set to promote the diffusion of active ingredients within the skin.

[0025] The method further comprises the steps of: providing guidance information corresponding to a skin treatment module applied according to skin condition to a terminal of a patient; receiving selection information based on the guidance information from the terminal of the patient; and providing post-treatment information of a skin treatment module corresponding to the selection information to the terminal of the patient based on the received selection information, wherein the guidance information includes at least one of the purpose of application, the target of application, an overview of action, a procedure for execution, precautions, and expected effects of the skin treatment module.

[0026] The step of providing the above guidance information includes simulating skin reaction results for multiple different skin treatment module application scenarios using a virtual skin model generated based on the skin condition of the subject of the procedure, visualizing the simulation results, and providing them to the terminal of the subject of the procedure, and the selection information may include information regarding a skin treatment module selected based on the simulation results.

[0027] In addition, a skin care device according to one embodiment based on the technical concept of the present invention may be characterized by comprising: a pretreatment unit for treating the skin surface; a stimulation unit for applying micro-stimulation to the skin; a supply unit for supplying an active ingredient to the skin; at least one skin treatment module among a lifting module for improving skin elasticity, a skin condition stabilization module for alleviating skin troubles, and a pigment alleviation module for improving skin tone; and a management unit for setting usage conditions or operating conditions of at least one of the skin treatment modules based on the skin condition.

[0028] The above skin condition stabilization module generates plasma, and the above pigment reduction module can generate a laser or light.

[0029] The above-mentioned stimulating part may include a micro-needle or rolling structure.

[0030] The skin care device further includes a sensing unit for detecting skin condition and skin reaction state, and the care unit sets usage conditions or operating conditions of at least one of the skin treatment modules based on the skin condition and skin reaction state detected by the sensing unit, and can dynamically reset the usage sequence, output intensity, and operating time of the skin treatment modules based on the skin condition and the skin reaction state after performing the previous step.

[0031] The above-mentioned sensing unit is configured to obtain microstructure data including the state of microchannel formation, surface roughness, and local density distribution of the skin by scanning the three-dimensional microstructure of the skin surface and epidermal layer at a resolution greater than a preset resolution, and the above-mentioned management unit predicts the diffusion path and diffusion speed of the active ingredient within the skin based on the above-mentioned microstructure data, sets the supply conditions of the active ingredient and the operating conditions of the skin treatment module according to the predicted diffusion path and diffusion speed, and the above-mentioned management unit can perform adaptive control to correct the operating conditions based on the difference between the predicted result and the actual measured skin reaction state.

[0032] The above-mentioned management unit provides guidance information corresponding to the skin treatment module applied according to the skin condition to the terminal of the subject of the procedure, receives selection information based on the guidance information from the terminal of the subject of the procedure, and provides post-treatment information of the skin treatment module corresponding to the selection information to the terminal of the subject of the procedure based on the received selection information, and the guidance information may include at least one of the purpose of application, the target of application, an overview of the action, a procedure for execution, precautions, and expected effects of the skin treatment module. Effects of the invention

[0033] According to the skin condition-based selective complex skin care method and skin care device based on the technical concept of the present invention, the following effects can be expected.

[0034] (1) Since at least one of the multiple skin treatment modules can be selectively applied depending on the skin condition, there is an effect of being able to flexibly perform skin care for different purposes, such as improving skin elasticity, alleviating skin troubles, and improving skin tone, in one integrated system.

[0035] (2) By analyzing the skin condition and selecting an appropriate skin treatment module based on the analysis results, customized care suitable for the skin condition is possible without relying on the experience of the user or manager, and the consistency and reproducibility of the care can be improved.

[0036] (3) Instead of multiple skin treatment modules being performed independently of each other, the intensity, depth, and sequence of stimulation applied to the skin are interconnected, and the conditions of execution are dynamically adjusted according to the skin reaction state, thereby enabling active response to changes in skin condition and more precise and stable skin care.

[0037] (4) By securing a delivery path for active ingredients through microchannels formed in the skin by micro-stimulation and sequentially supplying active ingredients with different viscosities, the penetration depth into the skin can be effectively controlled and the delivery efficiency of the active ingredients can be improved.

[0038] (5) By irradiating the skin with light energy to finely reduce pigment particles and inducing them to be removed through internal circulation or lymphatic flow, it is possible to efficiently achieve skin tone improvement and pigment reduction effects.

[0039] (6) By controlling the microbial environment on the skin surface using plasma or active species, it is possible to stabilize the skin condition and alleviate the skin's reaction to external stimuli.

[0040] (7) By the interaction between the light-absorbing substance applied to the skin surface and the light energy, a localized heat reaction is induced, which promotes the diffusion of active ingredients within the skin and can increase the skin care effect.

[0041] (8) By dynamically resetting the operating sequence, output intensity, and operating time between multiple processing modules based on the skin condition and the results of the previous processing, it is possible to maintain optimal processing conditions according to the skin condition and to achieve efficient skin care while preventing excessive irritation.

[0042] (9) With the above configuration, it is possible to manage various complex skin conditions more comprehensively and systematically compared to a single-function center, and it is possible to stably maintain the effect of improving the appearance of the skin. Brief explanation of the drawing

[0048] Hereinafter, embodiments based on the technical concept of the present invention will be described in detail in turn.

[0049] FIG. 1 is a block diagram illustrating a skin care device according to one embodiment of the technical concept of the present invention.

[0050] As illustrated in FIG. 1, a skin care device (100) according to one embodiment of the present invention may include a pretreatment unit (110), a stimulation unit (120), a supply unit (130), a skin treatment module (140), a management unit (150), and a sensing unit (160).

[0051] The pretreatment unit (110) may be configured to clean the skin surface and organize the stratum corneum of the skin to form an environment for the absorption of active ingredients. The pretreatment unit (110) can make the skin clean by removing contaminants, sebum, waste products, or residual makeup ingredients present on the skin surface, and can organize the uneven stratum corneum of the skin surface to form a condition that allows subsequent skin care to be performed more smoothly.

[0052] The pretreatment unit (110) can operate by physically wiping the skin surface, applying and removing a cleanser, or homogenizing the stratum corneum while smoothing the skin texture. Here, the cleanser may be provided in a liquid, gel, cream, foam, lotion, or pad-impregnated form, and may be configured to keep the skin surface clean while reducing skin irritation. Additionally, the cleanser may include moisturizing ingredients, soothing ingredients, or a mildly acidic composition to enable cleansing while maintaining the skin's moisture balance. Furthermore, the cleanser may include ingredients for smoothing the stratum corneum of the skin in addition to simple cleansing functions. For example, the cleanser may include ingredients that alleviate or soften old dead skin cells on the skin surface, ingredients that smooth the skin texture, or ingredients that improve the absorption environment for subsequent active ingredients. Thus, the pretreatment unit (110) can create a basic environment to increase the absorption efficiency of the active ingredients provided to the skin.

[0053] The stimulating portion (120) may be configured to provide micro-stimulation to the skin to promote the delivery of active ingredients into the skin. The stimulating portion (120) may form micro-channels in the skin by applying physical stimulation to the surface of the skin or the upper layer of the skin, thereby allowing the active ingredients supplied in subsequent steps to be delivered more smoothly into the skin. Additionally, the intensity, depth, number of repetitions, and application time of stimulation may be set differently depending on the skin condition, the application area, or the purpose of use.

[0054] The stimulating portion (120) may include micro-needles or a rolling structure. The micro-needles may be a plurality of micro-protrusion structures that contact the skin to provide fine stimulation to the surface or epidermal layer of the skin. The micro-needles may be formed to have a specific length, spacing, and arrangement structure, and may form a fine stimulation path on the skin by contacting or pressing into the skin. At this time, the shape, length, arrangement density, and material of the micro-needles may be varied according to the skin condition, application area, or purpose of use.

[0055] Additionally, the stimulating portion (120) may include a rolling structure. The rolling structure may be a roller-shaped structure having a plurality of protrusions or micro-stimulating elements formed on its outer surface, and may provide repetitive micro-stimulation while rolling along the skin surface. The rolling structure may provide relatively uniform stimulation over a large area of ​​the skin and may adjust the direction of stimulation, stimulation density, and application range according to the user's operation or the movement of the device. Accordingly, the rolling structure may be operated in a manner that provides continuous stimulation along the skin texture or provides intensive stimulation to a specific area.

[0056] The microchannels formed by the stimulating part (120) may be fine passages or pathways extending from the skin surface toward the interior of the skin. These microchannels may be formed temporarily within a range that does not substantially damage the skin tissue and may serve to partially relax the barrier function of the skin surface to promote the penetration of active ingredients. The depth, diameter, density, and formation pattern of the microchannels may vary depending on the structure of the stimulating part (120), the stimulation conditions, or the skin condition. For example, microchannels in a dotted or arrayed form may be formed by microneedles, and microchannels in a linear or repeating array form may be formed by a rolling structure.

[0057] Accordingly, the stimulating part (120) can improve the delivery efficiency of active ingredients for improving the appearance of the skin by forming microchannels in the skin using micro-needles or a rolling structure, and enable the action of the skin treatment module performed in the subsequent step to be carried out more effectively.

[0058] The supply unit (130) may be configured to supply an active ingredient to the skin. The supply unit (130) may provide an active ingredient for improving the appearance of the skin to the skin surface or inward toward the skin, while the skin surface is prepared by the pretreatment unit (110) and micro-stimulation is applied to the skin by the stimulation unit (120). Accordingly, the supply unit (130) may enable the active ingredient to be delivered more smoothly through an absorption environment or micro-channel formed on the skin.

[0059] The supply unit (130) may operate by applying or spraying an active ingredient onto the skin surface, and may also operate by repeatedly supplying a certain amount of the active ingredient or supplying multiple active ingredients sequentially as needed. Additionally, the supply unit (130) may set the supply amount, supply speed, supply time, and supply order differently depending on the viscosity, concentration, composition, or purpose of use of the active ingredient. For example, the supply unit (130) may supply a low-viscosity ingredient first to induce initial penetration into the skin, and then supply a high-viscosity ingredient to allow it to remain on the skin surface or upper layer of the skin for a longer period. Here, the low-viscosity ingredient is 25 It may refer to components whose viscosity measured at is below the preset standard, and high-viscosity components are 25 It may refer to a component whose viscosity measured therein exceeds the aforementioned preset standard. Here, viscosity may be measured by a Brookfield viscometer, a rotational viscometer, or an equivalent viscosity measuring means. A low-viscosity component may be advantageous for improving delivery or diffusion within the skin, while a high-viscosity component may be advantageous for improving adhesion, coating properties, or persistence on the skin surface. Therefore, when a low-viscosity component and a high-viscosity component are included together, a balance of initial delivery and skin surface retention can be ensured.

[0060] Here, the active ingredient may be a functional ingredient provided to the skin to improve the appearance of the skin. The active ingredient may include ingredients for moisturizing, soothing, improving elasticity, improving skin texture, improving skin tone, or protecting the skin. For example, the active ingredient may include at least one of hyaluronic acid, collagen, peptides, plant-derived extracts, and panthenol. Hyaluronic acid may contribute to maintaining skin moisture and forming a moisturizing environment, collagen may help maintain skin elasticity or improve skin texture, and peptides may act as signaling ingredients to enhance skin vitality or improve skin condition. Additionally, plant-derived extracts may be utilized as ingredients for soothing or protecting the skin, and panthenol may contribute to protecting the skin barrier and soothing action.

[0061] The active ingredient may be provided in the form of a liquid, gel, serum, ampoule, cream, or mask, and may be provided as a single ingredient or as a composition in which multiple ingredients are mixed. Additionally, the active ingredient may be supplied selectively depending on the skin condition, the application area, or the purpose of use. For example, if skin dryness is predominant, an active ingredient with a high proportion of moisturizing ingredients may be supplied, and if skin soothing is required, an active ingredient containing a relatively large amount of soothing or skin-protecting ingredients may be supplied.

[0062] Accordingly, the supply unit (130) can more efficiently achieve the effect of improving the appearance of the skin by utilizing the skin environment created by the pretreatment unit (110) and the stimulation unit (120) by supplying an active ingredient suitable for the skin condition or purpose of use in an appropriate manner.

[0063] The skin treatment module (140) may be a configuration that is selectively applied according to the skin condition to improve the appearance of the skin. The skin treatment module (140) may include at least one of a lifting module (141) for improving skin elasticity, a skin condition stabilization module (142) for alleviating skin troubles, and a pigmentation alleviation module (143) for improving skin tone. Accordingly, the skin treatment module (140) may perform different types of skin treatment depending on the type of skin condition, the item requiring improvement, or the purpose of use.

[0064] The lifting module (141) included in the skin treatment module (140) may be configured to perform treatment for improving skin elasticity or refining the skin contour. The lifting module (141) may act by spreading stimulation from the center of the skin outward, or by moving the skin upward or inward. Accordingly, the lifting module (141) may apply physical or mechanical stimulation to the skin tissue to alleviate sagging of the skin or to refine the skin line. Additionally, the lifting module (141) may vary the direction of stimulation, direction of movement, number of repetitions, or application time depending on the application area.

[0065] The skin condition stabilization module (142) included in the skin treatment module (140) may be configured to perform treatment for alleviating skin troubles or stabilizing the skin surface environment. The skin condition stabilization module (142) may control the microbial environment on the skin surface using plasma or active species. For example, the skin condition stabilization module (142) may function to control the microbial environment present on the skin surface or to maintain the skin surface condition in a cleaner and more stable state. Here, the active species may include at least one of nitrogen oxides (NO), hydroxyl radicals (OH), reactive oxygen species (ROS), and nitrogen-derived compounds. Accordingly, the skin condition stabilization module (142) may enable more stable management of the skin condition in a state where skin irritation is a concern or where skin troubles are likely to occur.

[0066] The pigmentation alleviation module (143) included in the skin treatment module (140) may be configured to perform treatment for improving skin tone or pigment-related appearance. The pigmentation alleviation module (143) may irradiate light energy to micronize pigment particles within the skin. Additionally, the micronized pigment particles may be induced to be removed by internal circulation or lymphatic flow. Furthermore, the pigmentation alleviation module (143) may interact with a light-absorbing material applied to the skin surface to induce a localized thermal reaction, thereby promoting the diffusion of active ingredients within the skin. Thus, the pigmentation alleviation module (143) may be used to alleviate skin tone imbalance, pigmentation, or skin tone issues.

[0067] A light-absorbing material may be a substance that selectively absorbs light energy irradiated from the outside and converts it into thermal energy. Such a light-absorbing material may be applied to the surface of the skin or placed in a location adjacent to the skin surface, and upon irradiation with light energy, it can absorb at least a portion of the irradiated energy to induce a local temperature increase or thermal response. Accordingly, light energy can act more efficiently in the area where the light-absorbing material is applied, and it can perform an auxiliary function that promotes the diffusion or penetration of active ingredients supplied into the skin.

[0068] In addition, the light-absorbing material can be selected to have absorption characteristics corresponding to the wavelength band of the irradiated light. For example, the light-absorbing material may be a material that has a relatively high absorption rate for light of a specific wavelength irradiated from a laser or light source. Therefore, even under the same light irradiation conditions, a more selective thermal response can be induced in the area where the light-absorbing material is present.

[0069] The light-absorbing material may be provided in the form of a composition that can be applied directly to the skin, for example, in a liquid, gel, cream, or impregnated form in a pad. Additionally, the light-absorbing material may be used alone or may be included together with moisturizing ingredients, soothing ingredients, viscosity-regulating ingredients, or auxiliary ingredients to improve skin applicability.

[0070] In addition, the light-absorbing material may be applied to be uniformly distributed on the skin surface, or it may be applied selectively to specific skin areas or areas of specific pigmentation. Accordingly, the location and intensity of the thermal reaction resulting from light energy irradiation can be controlled, and more precise skin care may be possible depending on the skin condition or the purpose of the procedure.

[0071] The skin treatment module (140) may be used independently for each of the modules, or two or more may be used in combination depending on the skin condition. For example, if skin elasticity loss and skin tone imbalance occur together, the lifting module (141) and the pigmentation alleviation module (143) may be applied together, and if skin trouble and skin barrier deterioration are concerns together, the skin condition stabilization module (142) may be applied first. In addition, the skin treatment module (140) is operated selectively according to the skin condition or purpose of use, so it is not limited to single-purpose skin treatment but can flexibly respond to complex skin conditions.

[0072] Accordingly, the skin treatment module (140) may be a key component that enables more customized improvement of the skin's appearance by allowing different skin treatment modules to be selectively applied depending on the skin condition.

[0073] The management unit (150) may be configured to set usage conditions or operating conditions for at least one of the skin treatment modules (140) based on the skin condition. The management unit (150) may manage the overall operation of the skin care device (100) by considering the skin condition, the application area, the purpose of use, or the skin reaction state after performing the previous step. Here, the skin reaction state may include at least one of the degree of erythema, heat sensation, change in sensitivity, change in moisture, degree of skin surface stabilization, or degree of irritation reaction that appear after pretreatment, micro-stimulation, supply of active ingredients, or application of the skin treatment module. Accordingly, the management unit (150) may set or reset at least one of the usage order, output intensity, operating time, or number of repetitions so that the pretreatment unit (110), stimulation unit (120), supply unit (130), and skin treatment module (140) operate organically with each other. Additionally, the management unit (150) may link the use or operation of the skin treatment module (140) by providing setting information or control signals corresponding to the set conditions to the skin treatment module (140).

[0074] Additionally, the management unit (150) may set at least one of the usage order, output intensity, operating time, and application conditions of the skin treatment module (140) based on the skin condition and the skin reaction condition after performing the previous step. The skin treatment module (140) may be selectively used or operated according to the conditions set by the management unit (150). At this time, the management unit (150) may be linked with the skin treatment module (140) by providing setting information, guidance information, or control signals to the skin treatment module (140). For example, the management unit (150) may set whether to apply first, the application order, the application time, the output intensity, or the number of repetitions for any one or more of the lifting module (141), the skin condition stabilization module (142), and the pigment reduction module (143), and the skin treatment module (140) may be used in a manual or semi-automatic manner accordingly.

[0075] The management unit (150) may be configured to selectively use at least one of the skin treatment modules, including the lifting module (141), the skin condition stabilization module (142), and the pigmentation alleviation module (143), depending on the skin condition. For example, the management unit (150) may be configured to increase the usage of the lifting module (141) when skin elasticity reduction is dominant, prioritize the usage conditions of the skin condition stabilization module (142) when skin trouble or skin surface instability is dominant, and set the operating conditions of the pigmentation alleviation module (143) when pigmentation or skin tone imbalance is dominant.

[0076] Additionally, the management unit (150) can dynamically change the usage conditions or operating conditions of the skin treatment module (140) according to the skin condition. Here, the usage conditions or operating conditions may include at least one of whether the skin treatment module is used, the order of use, the operating time, the output intensity, the number of repetitions, the application interval, or the application area. For example, even when the same skin treatment module is applied, the management unit (150) can set the operating time to be short or long depending on the skin condition, set the output intensity to be increased or decreased, and when multiple skin treatment modules are applied, set the order of use differently.

[0077] The management unit (150) may also adjust subsequent treatment conditions by reflecting the skin reaction state that appeared after the previous step was performed. For example, the management unit (150) may adjust the conditions for performing light energy irradiation or antibacterial treatment based on the skin reaction state, such as the recovery speed after stimulation, the amount of moisture change, or the change in surface impedance.

[0078] In one embodiment, the recovery rate after stimulation may refer to the speed at which the surface temperature, degree of erythema, sensitivity, electrical characteristics, or other response indicators of the skin return to a reference state or a preset stable range after skin treatment such as micro-stimulation, light energy irradiation, antimicrobial treatment, or supply of active ingredients. For example, the recovery rate after stimulation may be calculated as at least one of the difference between a value measured immediately after stimulation and a value measured after a preset time has elapsed, the time required to return to a reference state, or the rate of change per unit time.

[0079] In one embodiment, the change in moisture may refer to the difference in the skin moisture status before and after a specific skin treatment. For example, the change in moisture may be at least one of the difference, rate of change, or ratio of skin moisture measurements before and after pretreatment, before and after micro-stimulation, before and after supplying an active ingredient, or before and after the application of a skin treatment module.

[0080] In one embodiment, the change in surface impedance may refer to the degree of change in electrical impedance of the skin surface before and after a specific skin treatment. For example, the change in surface impedance may include at least one of the absolute difference in skin surface impedance measured at a preset frequency or a plurality of frequency bands, the rate of change, or trend information between a plurality of time points.

[0081] In one embodiment, the conditions for performing light energy irradiation may include at least one of irradiation intensity, irradiation time, number of irradiations, irradiation cycle, irradiation interval, irradiation area, irradiation position, irradiation wavelength, irradiation mode, whether continuous irradiation is performed, whether pulsed irradiation is performed, pulse width, duty cycle, and combination ratio of multiple light sources.

[0082] In one embodiment, the conditions for performing the antimicrobial treatment may include at least one of the antimicrobial treatment intensity, treatment time, number of treatments, treatment cycle, treatment interval, treatment area, treatment location, amount of energy applied, emission density, amount of spray, spray pressure, amount of active species generated, concentration of active species, contact time, and combination ratio of multiple antimicrobial means.

[0083] Accordingly, the management unit (150) can set the usage conditions or operating conditions of the skin treatment module (140) so that the intensity of the stimulation or treatment applied to the skin, the order of execution, and the operating time are interconnected.

[0084] Accordingly, the management unit (150) may be configured to organically link each component of the skin care device (100) according to the skin condition and skin reaction state, and to dynamically set the usage conditions or operating conditions of the skin treatment module (140), thereby enabling more precise and efficient improvement of the appearance of the skin.

[0085] The management unit (150) can set at least one of the usage order, output intensity, operating time, and application conditions of the skin treatment module (140) based on the skin condition and the skin reaction condition after performing the previous step.

[0086] The management unit (150) can set the above conditions based on the detection results of the detection unit (160) or user input information. At this time, the management unit (150) can be linked with the skin processing module (140) by providing setting information to the skin processing module (140) or transmitting control signals. The skin processing module (140) can be selectively used or operated according to the conditions set by the management unit (150).

[0087] The sensing unit (160) may be configured to detect skin conditions. The sensing unit (160) may detect at least one of the skin's moisture condition, surface temperature, surface impedance, tone condition, elasticity condition, skin trouble condition, or reaction condition after stimulation. The sensing unit (160) may be composed of an optical sensor, a temperature sensor, a contact sensor, an impedance sensor, an image acquisition unit, or a combination thereof, and may acquire information regarding the skin condition from the skin surface or an area adjacent to the skin.

[0088] In one embodiment, the sensing unit (160) may be configured to scan the three-dimensional microstructure of the skin surface and the epidermal layer. The three-dimensional microstructure scanning may be performed using at least one of an optical method, a laser scanning method, a structured light method, or an interference-based measurement method, and may acquire micro-shape information of the skin at a resolution greater than a preset resolution.

[0089] The microstructure data obtained through the above microstructure scan may include skin surface roughness, microchannel formation status, local density distribution of skin tissue, micro-irregularity structure, and pathway information formed by stimulation. This microstructure data can be utilized as a key factor in determining the penetration pathway and diffusion characteristics of the active ingredient.

[0090] The management unit (150) can predict the diffusion path and diffusion rate of the active ingredient within the skin based on the microstructure data. For example, the management unit (150) can calculate the path through which the active ingredient can move into the skin based on the depth, density, and connection structure of the microchannels, and estimate the diffusion rate based on the local density or resistance characteristics of the skin tissue.

[0091] Additionally, the management unit (150) can set the supply conditions of the active ingredient, e.g., supply order, supply amount, supply rate, and supply time, and the operating conditions of the skin treatment module (140), e.g., output intensity, irradiation time, application order, and number of repetitions, based on the predicted diffusion path and diffusion rate.

[0092] In one embodiment, the control unit (150) can perform adaptive control to correct operating conditions by comparing the difference between the predicted result and the actual measured skin reaction state. For example, if the actual skin reaction is excessive compared to the prediction, the control conditions can be corrected by reducing the output intensity or operating time, and conversely, if the skin reaction is weak, by increasing the output intensity or operating time.

[0093] In addition, the above adaptive control can be performed repeatedly over multiple stages and can be progressively corrected in a direction that minimizes the error between the predicted result and the actual response in the previous stage. Accordingly, individualized control based on skin condition becomes possible, and the efficiency of active ingredient delivery and skin care effects can be improved.

[0094] Accordingly, according to the present embodiment, through diffusion prediction and adaptive control that precisely reflects the microstructure of the skin, the operating conditions of the skin treatment module can be set more precisely, and skin care optimized for the skin condition becomes possible.

[0095] Additionally, the sensing unit (160) may detect the initial skin condition before skin care, or may detect the skin reaction state after pretreatment, micro-stimulation, supply of active ingredients, or application of a skin treatment module. Accordingly, the sensing unit (160) may provide the management unit (150) with a change in the skin condition or the skin reaction state after performing the previous step.

[0096] The management unit (150) can set the usage conditions or operating conditions of at least one of the skin treatment modules (140) based on the detection results of the detection unit (160). For example, if the skin condition detected by the detection unit (160) corresponds to a decrease in skin elasticity, the management unit (150) can set the usage conditions of the lifting module (141); if it corresponds to a skin trouble or an unstable skin surface condition, it can set the usage conditions of the skin condition stabilization module (142); and if it corresponds to pigmentation or skin tone imbalance, it can set the usage conditions of the pigment alleviation module (143).

[0097] Accordingly, the sensing unit (160) may be configured to support skin care suitable for the skin condition by acquiring information regarding the skin condition in real time or in stages and providing it to the management unit (150).

[0098] According to the skin care device (100) of the present embodiment, at least one of a plurality of skin treatment modules (140) can be selectively applied depending on the skin condition, thereby enabling integrated skin care for different purposes, such as improving skin elasticity, alleviating skin troubles, and improving skin tone. Additionally, since the skin condition can be analyzed and an appropriate skin treatment module (140) can be selected based on the analysis results, customized care suitable for the skin condition is possible, and the consistency and reproducibility of the care can be improved. Furthermore, since the performance conditions of the plurality of skin treatment modules can be synchronized and controlled according to the skin reaction state, more precise and stable skin care is possible while actively responding to changes in the skin condition. In addition, active ingredients can be delivered into the skin through microchannels formed by micro-stimulation, and multiple active ingredients having different viscosities can be supplied sequentially, thereby improving the penetration depth and delivery efficiency of the active ingredients. Furthermore, since pigment alleviation, skin condition stabilization, and active ingredient diffusion promotion effects can be realized through light energy irradiation, plasma or active species treatment, and interaction with light-absorbing materials, more systematic and efficient improvement of the skin appearance is possible for various complex skin conditions.

[0099] FIGS. 2 and 3 are drawings illustrating guidance information for a lifting module of a skin care device according to an embodiment of the technical concept of the present invention, FIGS. 4 and 5 are drawings illustrating guidance information for a skin condition stabilization module of a skin care device according to an embodiment of the technical concept of the present invention, and FIGS. 6 and 7 are drawings illustrating guidance information for a pigment alleviation module of a skin care device according to an embodiment of the technical concept of the present invention.

[0100] Meanwhile, the management unit (150) can perform the function of managing the operation of each component within the skin care device (100), as well as the function of transmitting and receiving information to and from the terminal of the subject of the procedure to ensure that guidance, selection, and post-care related to skin care are continuously performed.

[0101] Here, the subject of the procedure may refer to a person who actually receives skin care using the skin care device (100). The subject of the procedure is not limited to simply being an object on which the procedure is performed, but may be an information recipient who receives guidance regarding a skin treatment module corresponding to the skin condition, selects a specific skin treatment module or aftercare item according to their skin condition or preference, and receives aftercare information corresponding to the selected skin treatment module. Additionally, the subject of the procedure may be a user who can provide information regarding their skin condition, discomfort, sensitivity, satisfaction, or intention to receive care at each point in time before, during, or after skin care.

[0102] The terminal of the treatment subject may refer to various information processing devices used by the treatment subject. For example, the treatment subject's terminal may be a smartphone, tablet PC, portable terminal, laptop, desktop terminal, kiosk, or wearable terminal. Such a terminal may include screen output functions, input functions, and communication functions, and may receive or input various information related to skin care through linkage with the management unit (150). As an example, the treatment subject's terminal may display guidance information on the screen and may be configured to allow the treatment subject to provide selection information through touch input, button input, voice input, or selection item input.

[0103] The management unit (150) may be connected directly or indirectly to the terminal of the patient undergoing treatment. For example, the management unit (150) may communicate directly with the patient's terminal through a communication module directly provided in the skin care device (100). Additionally, the management unit (150) may communicate with the patient's terminal while linked to an external server, a cloud system, or a separate management system. In this case, the skin care device (100), the external server, and the patient's terminal may be interconnected via a wired or wireless network. More specifically, the management unit (150) may transmit and receive data with the patient's terminal using Bluetooth, Bluetooth Low Energy Communication, short-range wireless communication, Wi-Fi, a mobile communication network, an Internet Protocol-based network, or a combination thereof.

[0104] The management unit (150) may be configured to provide guidance information to the terminal of the subject of the procedure. Here, the guidance information may be explanatory information regarding a skin treatment module that can be applied according to the skin condition. The guidance information may include at least one of the following: the purpose of application, the target of application, an overview of the action, the procedure of execution, precautions, expected effects, the management cycle, ingredients used, expected reactions, recommended post-treatment care methods, or frequently asked questions regarding the skin treatment module. For example, guidance information corresponding to a lifting module may include the purpose of improving skin elasticity, the recommended target skin condition, the basic principles of lifting care, the management procedure, the active ingredients used, precautions after the procedure, and expected appearance improvement effects (see FIGS. 2 and 3). Additionally, guidance information corresponding to a skin condition stabilization module may include the target of application for sensitive skin or troubled skin, the principles of controlling the skin surface environment, the stabilization management process, precautions, and post-treatment care methods (see FIGS. 4 and 5). In addition, guidance information corresponding to the pigmentation reduction module may include the purpose of skin tone improvement, skin condition related to pigmentation, principle of light irradiation, expected treatment process, reaction after treatment, and precautions (see FIGS. 6 and 7).

[0105] In one embodiment, the management unit (150) may be configured to generate a virtual skin model based on the skin condition of the subject of the procedure. The virtual skin model may be generated by reflecting skin condition information obtained by the sensing unit (160), such as the skin's moisture condition, elasticity condition, tone condition, surface impedance, degree of microchannel formation, and skin response history data. This virtual skin model may be a digital model that mimics the actual skin condition of the subject of the procedure and may include the skin's layered structure, physical properties, and stimulation response properties.

[0106] The management unit (150) can simulate skin reaction results for a plurality of different skin treatment module application scenarios using the virtual skin model. Here, the skin treatment module application scenarios can be defined by combining the selection of at least one of the lifting module (141), the skin condition stabilization module (142), and the pigment reduction module (143), the application order, the operating conditions, and the number of repetitions.

[0107] The above simulation can be performed in a manner that predicts changes in skin elasticity, the degree of pigment reduction, the degree of skin reaction, the diffusion range of active ingredients, and skin recovery characteristics for each scenario. The management unit (150) can visualize the results of the above simulation in the form of a graph, a color change map, a three-dimensional model, or a step-by-step change image and provide them to the terminal of the subject of the procedure.

[0108] The subject of the procedure may select at least one of a plurality of skin treatment scenarios based on the visualized simulation results above, and the subject's selection information may be entered based on the results of comparing or analyzing the simulation results above.

[0109] The management unit (150) can set the application conditions of the skin treatment module corresponding to the selected scenario or provide post-management information.

[0110] Accordingly, according to the present embodiment, by providing simulation results based on a virtual skin model before actual skin treatment, the subject of the procedure can predict the skin treatment results in advance and select the optimal skin treatment module based thereon.

[0111] The management unit (150) may be configured to receive selection information from the terminal of the subject of the procedure. Here, the selection information may be information entered by the subject of the procedure based on guidance information. The selection information may include at least one of the following: whether to select a specific skin treatment module, desired treatment items, desired intensity, priority treatment purpose, whether to request additional explanation, whether to receive post-treatment information, whether to check warnings, or a follow-up treatment intention. For example, the subject of the procedure may check the explanation regarding the lifting module through their terminal and then choose to receive post-treatment information related to that module, and may selectively request additional explanation or precautions regarding a specific module among the skin condition stabilization module or the pigmentation alleviation module.

[0112] The management unit (150) may provide post-treatment information corresponding to the selected skin treatment module based on the received selection information to the terminal of the subject of the procedure. Here, the post-treatment information may be information intended to maintain the skin condition stably after the procedure or to assist in the effect of improving the appearance of the skin. For example, the post-treatment information may include at least one of the following: timing of washing, washing method, necessity of UV protection, method of maintaining moisture, avoidance of external stimuli, recommended use of cosmetics or products, lifestyle habits to avoid for a certain period, method of responding in case of skin reaction, time for future treatment, or recommended time for revisit. Additionally, the post-treatment information may be configured differently depending on the type of selected skin treatment module. For example, if a lifting module is selected, management methods related to maintaining skin elasticity may be primarily provided; if a skin condition stabilization module is selected, information related to alleviating sensitive reactions and minimizing skin irritation may be primarily provided; and if a pigmentation alleviation module is selected, information related to avoiding light exposure, UV protection, and maintaining skin tone may be primarily provided.

[0113] The management unit (150) may not merely transmit and receive information, but may also personalize information in conjunction with skin condition. For example, based on skin condition information or procedure history information received from the detection unit (160), the management unit (150) may provide different guidance information or different post-treatment care information to the treatment subject's terminal even for the same skin processing module. That is, the management unit (150) may set the content of information provision differently, such as prioritizing information centered on precautions for treatment subjects with sensitive skin, and providing information centered on lifting maintenance for treatment subjects whose main objective is to improve skin elasticity.

[0114] Additionally, the management unit (150) may track the post-treatment care process by repeatedly receiving information from the terminal of the treatment subject. For example, the management unit (150) may receive input regarding skin reaction, whether post-treatment care is performed, whether there are symptoms of discomfort, whether the product is used, or satisfaction information from the terminal of the treatment subject, and based on this information, may provide additional post-treatment care information or correct the usage conditions or operating conditions of the next skin treatment module. Accordingly, the management unit (150) can perform integrated management functions including not only the operation management of the skin care device (100), but also pre-treatment guidance, guidance on post-treatment care, reflection of user input, and support for follow-up care.

[0115] Additionally, the management unit (150) may be configured to store, update, or retransmit information provided to the terminal of the treatment subject. For example, the management unit (150) may store guidance information, selection information, and post-treatment care information already provided to the treatment subject, and may provide additional information or supplementary information based on the history of previously provided information when the same treatment subject accesses through the terminal in the future. Accordingly, the treatment subject can continuously check information linked to the skin care content performed by the skin care device (100) through their terminal, and can more easily receive practical behavioral guidelines after skin care.

[0116] FIG. 8 is a flowchart illustrating a skin care method according to one embodiment of the technical concept of the present invention.

[0117] As illustrated in FIG. 8, a skin care method according to one embodiment of the present invention may include a cleansing step (S110), a pretreatment step (S120), a micro-stimulation step (S130), and a skin treatment module application step (S140). Hereinafter, the skin care method will be described with a focus on the skin care device (100).

[0118] The cleansing step (S110) may be a step for cleansing the surface of the skin. The cleansing step (S110) may be a step for preparing the skin to a clean state by removing at least one of sebum, contaminants, waste products, residual cosmetic ingredients, or external foreign substances present on the skin surface. This can form a basic state that allows for smoother application of pretreatment, micro-stimulation, and skin treatment modules performed in subsequent steps.

[0119] In one embodiment, the cleaning step (S110) may be performed by a pretreatment unit (110) of the skin care device (100). The pretreatment unit (110) may operate by physically wiping the skin surface, applying and then removing a cleansing agent to the skin, or cleaning the skin surface using a pad, brush, sheet, or absorbent material. Additionally, the cleaning step (S110) may be performed such that the cleaning intensity, cleaning time, or type of cleansing agent is set differently depending on the moisture state or sensitivity of the skin surface.

[0120] Additionally, the cleanser used in the cleansing step (S110) may be provided in a liquid, gel, cream, foam, lotion, or pad-impregnated form. The cleanser may include at least one of a mildly acidic composition, a moisturizing ingredient, a soothing ingredient, or a surfactant ingredient so as to cleanse the skin surface while reducing skin irritation. For example, the cleanser may be configured to remove impurities from the skin surface while maintaining the skin's moisture balance.

[0121] Meanwhile, the cleansing step (S110) is not limited to a step of simply removing contaminants, but can also perform the function of preparing the skin surface condition so that the stratum corneum can be more uniformly organized in the subsequent pretreatment step (S120). Therefore, the cleansing step (S110) can function as a step that forms a foundational environment for the subsequent skin care to be performed stably in the initial stage of the skin care method.

[0122] The pretreatment step (S120) may be a step of preparing the stratum corneum of the skin to form an environment for the absorption of active ingredients. The pretreatment step (S120) may be a step for uniformly adjusting the condition of the stratum corneum on the skin surface that has been cleaned through the cleansing step (S110), preparing the skin texture, and forming a condition in which active ingredients supplied in subsequent steps can be delivered to the skin more effectively.

[0123] In one embodiment, the pretreatment step (S120) may be performed by a pretreatment unit (110) of a skin care device (100). The pretreatment unit (110) may operate by gently rubbing or wiping the skin surface, arranging it along the skin texture, or providing a composition to the skin that softens or soothes the stratum corneum. Accordingly, the uneven stratum corneum on the skin surface is arranged, and the skin surface condition can be formed more uniformly.

[0124] In addition, different pretreatment methods may be applied in the pretreatment step (S120) depending on the skin condition. For example, for dry skin, a composition containing moisturizing ingredients may be used to gently smooth the stratum corneum, and for skin with a rough or thick stratum corneum, a composition containing exfoliating ingredients or skin texture smoothing ingredients may be applied. Additionally, for sensitive skin, a hypoallergenic composition or a composition containing soothing ingredients may be used to reduce irritation.

[0125] The composition used in the pretreatment step (S120) may be provided in a liquid, gel, lotion, cream, or pad-impregnated form, and may be configured to regulate the condition of the skin surface without causing excessive irritation to the skin. For example, the pretreatment composition may include at least one of a skin moisturizing ingredient, a soothing ingredient, an exfoliating ingredient, a skin texture regulating ingredient, or an ingredient that assists in the subsequent absorption of an active ingredient.

[0126] Accordingly, the pretreatment step (S120) can function as a step that forms a foundation for the subsequent micro-stimulation step (S130) and skin treatment module application step (S140) to be performed more stably and effectively by organizing the stratum corneum on the skin surface and forming a uniform skin texture.

[0127] In one embodiment, a step of analyzing the skin condition may be further performed after the pretreatment step (S120) and before the micro-stimulation step (S130). Here, the skin condition may include at least one of the degree of skin elasticity reduction, the presence or degree of skin trouble, the pigmentation state, the uniformity of skin tone, sensitivity, moisture state, and skin surface state, and the analysis results may be used to set the stimulation intensity, depth, number of repetitions, or application time of the micro-stimulation step (S130), and the type, application order, or operating conditions of the skin treatment module selected in the skin treatment module application step (S140).

[0128] The micro-stimulation step (S130) may be a step of applying micro-stimulation to the skin to promote the delivery of active ingredients into the skin. The micro-stimulation step (S130) may be a step of inducing a temporary reaction in the skin by applying micro-physical stimulation to the surface or epidermal layer of the skin, and forming a condition in which subsequently supplied active ingredients can be delivered more smoothly into the skin.

[0129] In one embodiment, the micro-stimulation step (S130) may be performed by a stimulation unit (120) of a skin care device (100). The stimulation unit (120) may include micro-needles, a rolling device, or a micro-vibration structure and may provide micro-stimulation while in contact with the skin or moving along the surface of the skin. For example, if the stimulation unit (120) includes micro-needles, a plurality of micro-protrusions may come into contact with the surface of the skin to form micro-channels on the surface of the skin or in the epidermal layer. Additionally, if the stimulation unit (120) includes a rolling structure, a plurality of stimulation protrusions or stimulation surfaces may move along the skin according to the rotation of the roller to provide continuous or repetitive micro-stimulation.

[0130] Here, the microchannel may be a fine passage or pathway temporarily formed on the skin surface by micro-stimulation. The microchannel acts as a fine delivery pathway extending inward from the surface of the skin, thereby inducing the active ingredient supplied in a subsequent step to penetrate more effectively into the skin rather than simply remaining on the skin surface. These microchannels may naturally recover or close over time.

[0131] Additionally, the stimulation applied in the micro-stimulation step (S130) may be set differently in intensity, depth, number of repetitions, direction of movement, or application time depending on the skin condition, application area, or purpose of use. For example, if the skin is sensitive, the depth or intensity of the stimulation may be set low, and if it is necessary to induce more active delivery of the active ingredient, the number of repetitions or application time of the stimulation may be increased. Furthermore, the direction or arrangement of the stimulation may be set considering the type of skin treatment module applied subsequently or the direction of the skin texture.

[0132] Accordingly, the micro-stimulation step (S130) can function as a step that improves the efficiency of the subsequent skin treatment step by forming a temporary micro-reaction on the skin surface and securing a delivery pathway for the active ingredient.

[0133] Meanwhile, after the micro-stimulation step (S130), the active ingredient provided to the skin can be delivered into the skin through micro-channels formed by the micro-stimulation. Here, the active ingredient may include at least one of hyaluronic acid, collagen, peptide, plant-derived extract, and panthenol. These active ingredients may be used to assist in moisturizing, soothing, improving elasticity, or restoring the skin condition.

[0134] In addition, in one embodiment, a plurality of active ingredients having different viscosities can be sequentially supplied into the skin through the microchannel. For example, a low-viscosity ingredient can be supplied first to penetrate to a relatively deep area of ​​the skin, and then a high-viscosity ingredient can be supplied to remain or diffuse in the upper or middle area of ​​the skin. Accordingly, the penetration depth of the active ingredients can be differentiated, and more efficient delivery of ingredients according to the skin condition can be achieved.

[0135] The skin treatment module application step (S140) may be a step of applying a skin treatment module according to the skin condition. The skin treatment module application step (S140) may be a step of improving the appearance of the skin by selectively applying a suitable skin treatment module to the skin that has undergone the pretreatment step (S120) and the micro-stimulation step (S130), taking into consideration skin conditions related to skin elasticity, skin troubles, skin tone, etc.

[0136] In one embodiment, a process of analyzing the skin condition may be further performed prior to or during the skin treatment module application step (S140). Here, the skin condition may include at least one of the degree of skin elasticity reduction, the presence or degree of skin trouble, the pigmentation condition, the uniformity of skin tone, sensitivity, moisture condition, and skin surface condition. And, based on the analysis results, at least one of the lifting module (141), the skin condition stabilization module (142), and the pigmentation alleviation module (143) may be selected.

[0137] For example, if the decrease in skin elasticity is relatively large, a lifting module (141) may be selected; if sensitive reactions or skin troubles on the skin surface are dominant, a skin condition stabilization module (142) may be selected; and if pigmentation or skin tone imbalance is prominent, a pigment alleviation module (143) may be selected. Additionally, if multiple skin conditions appear together, two or more skin treatment modules may be selected in combination.

[0138] In one embodiment, the skin treatment module application step (S140) may be performed by the skin treatment module (140) of the skin care device (100). The skin treatment module (140) may include at least one of a lifting module (141), a skin condition stabilization module (142), and a pigmentation alleviation module (143). Additionally, the skin treatment module application step (S140) may be performed based on usage conditions or operating conditions set or adjusted by the management unit (150).

[0139] Specifically, the lifting module (141) can be applied to improve skin elasticity. The lifting module (141) can act by spreading stimulation from the center of the skin outward, or by moving the skin upward or inward. Accordingly, physical or complex stimulation is applied to the skin tissue, thereby inducing improvement in skin elasticity, contouring, or relief of sagging.

[0140] Additionally, the skin condition stabilization module (142) may be applied to alleviate skin troubles or stabilize the skin surface environment. The skin condition stabilization module (142) may control the microbial environment on the skin surface using plasma or active species. For example, the skin condition stabilization module (142) may act to alleviate the unbalanced environment on the skin surface by irradiating plasma onto the skin surface or providing active species, and to maintain the skin in a more stable state. Here, the active species may include at least one of nitrogen oxides (NO), hydroxyl radicals (OH), reactive oxygen species (ROS), and nitrogen-derived compounds.

[0141] Meanwhile, the pigmentation alleviation module (143) may be applied to improve skin tone or alleviate pigmentation. The pigmentation alleviation module (143) may irradiate light energy to micronize pigment particles within the skin. Accordingly, the micronized pigment particles may be induced to be removed by internal circulation or lymphatic flow, thereby achieving uniformity of skin tone or alleviation of pigmentation. Additionally, in one embodiment, the pigmentation alleviation module (143) may interact with a light-absorbing material applied to the surface of the skin to induce a localized thermal reaction, and said thermal reaction may act to promote the diffusion of active ingredients within the skin.

[0142] A light-absorbing material may be a substance that selectively absorbs light energy irradiated from the outside and converts it into thermal energy. Such a light-absorbing material may be applied to the surface of the skin or placed in a location adjacent to the skin surface, and upon irradiation with light energy, it can absorb at least a portion of the irradiated energy to induce a local temperature increase or thermal response. Accordingly, light energy can act more efficiently in the area where the light-absorbing material is applied, and it can perform an auxiliary function that promotes the diffusion or penetration of active ingredients supplied into the skin.

[0143] In addition, the light-absorbing material can be selected to have absorption characteristics corresponding to the wavelength band of the irradiated light. For example, the light-absorbing material may be a material that has a relatively high absorption rate for light of a specific wavelength irradiated from a laser or light source. Therefore, even under the same light irradiation conditions, a more selective thermal response can be induced in the area where the light-absorbing material is present.

[0144] The light-absorbing material may be provided in the form of a composition that can be applied directly to the skin, for example, in a liquid, gel, cream, or impregnated form in a pad. Additionally, the light-absorbing material may be used alone or may be included together with moisturizing ingredients, soothing ingredients, viscosity-regulating ingredients, or auxiliary ingredients to improve skin applicability.

[0145] In addition, the light-absorbing material may be applied to be uniformly distributed on the skin surface, or it may be applied selectively to specific skin areas or areas of specific pigmentation. Accordingly, the location and intensity of the thermal reaction resulting from light energy irradiation can be controlled, and more precise skin care may be possible depending on the skin condition or the purpose of the procedure.

[0146] Additionally, in one embodiment, light energy irradiation by the pigment alleviation module (143) can interact with a light-absorbing material applied to the surface of the skin to induce a localized thermal reaction. Here, the light-absorbing material may be a component capable of selectively absorbing the irradiated light energy, and the thermal reaction may act to promote the diffusion of the active ingredient supplied into the skin. Accordingly, the efficiency of the distribution of the active ingredient within the skin can be increased along with the pigment alleviation action.

[0147] Additionally, in the skin treatment module application step (S140), only one skin treatment module may be applied, or multiple skin treatment modules may be applied in combination. For example, if skin elasticity loss and skin tone imbalance occur together, a lifting module (141) and a pigmentation alleviation module (143) may be applied together. Furthermore, if skin troubles and skin sensitivity reactions occur together, a skin condition stabilization module (142) may be applied first, and then other modules may be applied additionally.

[0148] Here, the skin response state may include at least one of the skin's recovery rate after stimulation, change in moisture content, or change in surface impedance. Additionally, the conditions for performing light energy irradiation or antimicrobial treatment may be set to change non-linearly according to this skin response state. For example, if the skin's recovery rate is slow or the surface stimulation response is significant, the output intensity or operating time may be set to decrease, and if the skin exhibits a relatively stable response state, the treatment may be set to be performed under preset or enhanced conditions.

[0149] In one embodiment, the recovery rate after stimulation may refer to the speed at which the surface temperature, degree of erythema, sensitivity, electrical characteristics, or other response indicators of the skin return to a reference state or a preset stable range after skin treatment such as micro-stimulation, light energy irradiation, antimicrobial treatment, or supply of active ingredients. For example, the recovery rate after stimulation may be calculated as at least one of the difference between a value measured immediately after stimulation and a value measured after a preset time has elapsed, the time required to return to a reference state, or the rate of change per unit time.

[0150] In one embodiment, the change in moisture may refer to the difference in the skin moisture status before and after a specific skin treatment. For example, the change in moisture may be at least one of the difference, rate of change, or ratio of skin moisture measurements before and after pretreatment, before and after micro-stimulation, before and after supplying an active ingredient, or before and after the application of a skin treatment module.

[0151] In one embodiment, the change in surface impedance may refer to the degree of change in electrical impedance of the skin surface before and after a specific skin treatment. For example, the change in surface impedance may include at least one of the absolute difference in skin surface impedance measured at a preset frequency or a plurality of frequency bands, the rate of change, or trend information between a plurality of time points.

[0152] In one embodiment, the conditions for performing light energy irradiation may include at least one of irradiation intensity, irradiation time, number of irradiations, irradiation cycle, irradiation interval, irradiation area, irradiation position, irradiation wavelength, irradiation mode, whether continuous irradiation is performed, whether pulsed irradiation is performed, pulse width, duty cycle, and combination ratio of multiple light sources.

[0153] In one embodiment, the conditions for performing the antimicrobial treatment may include at least one of the antimicrobial treatment intensity, treatment time, number of treatments, treatment cycle, treatment interval, treatment area, treatment location, amount of energy applied, emission density, amount of spray, spray pressure, amount of active species generated, concentration of active species, contact time, and combination ratio of multiple antimicrobial means.

[0154] In one embodiment, the fact that the performance condition changes non-linearly according to the skin reaction state may mean that the performance condition does not change at the same proportional rate with respect to the amount of change in the skin reaction state, but rather changes at a different rate or in a different way according to a preset threshold, interval, weight, functional relationship, or rule set. For example, if the skin reaction state is below a first criterion, the performance condition may be maintained or slightly increased; if it is above the first criterion but below the second criterion, the performance condition may be gradually decreased; and if it is above the second criterion, the performance condition may be rapidly decreased or temporarily suspended.

[0155] As another example, the performance condition may be determined according to an exponential function, a logarithmic function, an interval function, a step function, or a preset lookup table, rather than a linear function for the skin response state.

[0156] As another example, even if the amount of change in the skin response state is the same, different weights are applied depending on which item among the recovery rate after stimulation, the amount of change in moisture, and the change in surface impedance has changed, so the performance conditions can be adjusted differently.

[0157] In addition, in one embodiment, micro-stimulation, antibacterial treatment, and light energy irradiation may be performed repeatedly on the same area with different time delays. In this case, the interval for repeated performance may be set based on the point at which the skin's temporary reaction decreases. Accordingly, by ensuring that the next treatment is performed after the skin's irritation reaction has subsided to a certain level, the burden on the skin can be reduced while improving skin care efficiency.

[0158] In one embodiment, the skin treatment module application step (S140) may be performed such that the application order, operating time, output intensity, or number of applications of the selected module are adjusted according to the skin condition. For example, the operating time of a specific skin treatment module may be extended or shortened, and the output intensity or application order may be changed, depending on the degree of skin reaction, changes in moisture, recovery state after stimulation, or surface condition. Additionally, the conditions for performing light energy irradiation or antimicrobial treatment may be configured to be adjusted in real time based on the skin reaction state formed by the micro-stimulation step (S130).

[0159] Accordingly, the skin treatment module application step (S140) can function as a step that enables the comprehensive achievement of multiple objectives, such as improving skin elasticity, stabilizing skin condition, and improving skin tone, by selectively or in combination applying appropriate skin treatment modules according to the skin condition and adjusting operating conditions as needed.

[0160] According to the skin care method of the present embodiment, at least one of a plurality of skin treatment modules (140) can be selectively applied depending on the skin condition, thereby enabling integrated skin care for different purposes, such as improving skin elasticity, alleviating skin troubles, and improving skin tone. Additionally, since the skin condition can be analyzed and an appropriate skin treatment module (140) can be selected based on the analysis results, customized care suitable for the skin condition is possible, and the consistency and reproducibility of the care can be improved. Furthermore, since the performance conditions of the plurality of skin treatment modules can be synchronized and controlled according to the skin reaction state, more precise and stable skin care is possible while actively responding to changes in the skin condition. Moreover, since active ingredients can be delivered into the skin through microchannels formed by micro-stimulation and multiple active ingredients having different viscosities can be supplied sequentially, the penetration depth and delivery efficiency of the active ingredients can be improved. Furthermore, since pigment alleviation, skin condition stabilization, and active ingredient diffusion promotion effects can be realized through light energy irradiation, plasma or active species treatment, and interaction with light-absorbing materials, more systematic and efficient improvement of the skin appearance is possible for various complex skin conditions.

[0161] Meanwhile, the skin care method of the present embodiment may further include a post-care linkage step (S150). The post-care linkage step (S150) may be a step of providing guidance information corresponding to a skin treatment module applied according to the skin condition to a terminal of the subject of the procedure. Here, the guidance information may include at least one of the purpose of application, the target of application, an overview of the action, a procedure for execution, precautions, and expected effects of the skin treatment module.

[0162] Additionally, in the post-treatment linkage step (S150), selection information based on the guidance information can be received from the terminal of the subject of the procedure. Here, the selection information may be information in which the subject of the procedure selects whether to provide a post-treatment program, a care guide, a precaution check item, or follow-up care information corresponding to a specific skin treatment module.

[0163] In addition, in the post-treatment linkage step (S150), post-treatment information of a skin treatment module corresponding to the received selection information can be provided to the terminal of the treatment subject based on the received selection information. For example, the post-treatment information may include at least one of precautions to minimize skin irritation after the procedure, the timing for washing the face or applying makeup, UV protection management, moisturizing or soothing management methods, information on usable products, a guide for responding to changes in skin condition, and follow-up care schedule information. Accordingly, the treatment subject can receive post-treatment information suitable for the applied skin treatment module to maintain the effects of the procedure or promote the stable recovery of the skin condition.

[0164] According to the skin care device (100) of the present embodiment, at least one of a plurality of skin treatment modules (140) can be selectively applied depending on the skin condition, thereby enabling integrated skin care for different purposes, such as improving skin elasticity, alleviating skin troubles, and improving skin tone. Additionally, since the skin condition can be analyzed and an appropriate skin treatment module (140) can be selected based on the analysis results, customized care suitable for the skin condition is possible, and the consistency and reproducibility of the care can be improved. Furthermore, since the performance conditions of the plurality of skin treatment modules can be synchronized and controlled according to the skin reaction state, more precise and stable skin care is possible while actively responding to changes in the skin condition. In addition, active ingredients can be delivered into the skin through microchannels formed by micro-stimulation, and multiple active ingredients having different viscosities can be supplied sequentially, thereby improving the penetration depth and delivery efficiency of the active ingredients. Furthermore, since pigment alleviation, skin condition stabilization, and active ingredient diffusion promotion effects can be realized through light energy irradiation, plasma or active species treatment, and interaction with light-absorbing materials, more systematic and efficient improvement of the skin appearance is possible for various complex skin conditions.
