[0044]FIG. 1 is a reference view illustrating a beauty system including a hydrogel discharge device according to an embodiment of the present invention.
[0045]FIGS. 2a to 2e are reference views illustrating skin beauty service provided through the beauty system including the hydrogel discharge device according to the embodiment of the present invention, wherein skin beauty service provided in a shop provided with the hydrogel discharge device 100 is illustrated.
[0046]FIG. 3 is a reference view illustrating skin state measurement according to an embodiment of the present invention.
[0047]Referring to FIGS. 1 and 2a, the face skin state of a user may be measured using a skin measurement device 50 or an electronic device that provides the same function.
[0048]The skin measurement device 50, which is a dedicated measurement device, may measure the face state of the user to acquire quantitative information, and may transmit the quantitative information to the hydrogel discharge device 100 and/or a predetermined electronic device. For example, as shown in FIG. 3, the skin measurement device 50 may measure the face skin state of the user for five respective regions of a face 10, such as a T zone, eye rims, nasolabial fold portions, the sides of the mouth, and a U zone, and may generate skin state information based on the measurement results.
[0049]In addition, the hydrogel discharge device 100 according to the embodiment of the present invention may receive the measured skin state information of the user's face 10 from the skin measurement device 50.
[0050]The face skin state information of the user may include at least one piece of information selected from among the size and shape of the user's face 10, result data measured for respective sensing items and respective facial regions, and skin state classification determined based on measured numerical values.
[0051]Here, the user may be a person who uses the hydrogel discharge device 100 at home or a person who receives skin care service in a shop provided with the hydrogel discharge device 100.
[0052]Meanwhile, in some embodiments, the skin measurement device 50 may capture an image of the face of the user using a camera module provided therein to acquire image data, and may transmit the image data to the hydrogel discharge device 100 and/or a predetermined electronic device.
[0053]Referring to FIG. 3, the user or a sales clerk may sequentially measure the five regions of the face 10 of the user, such as the T zone, the eye rims, the nasolabial fold portions, the sides of the mouth, and the U zone, using the skin measurement device 50.
[0054]The user or the sales clerk may make the skin measurement device 50 contact a total of 5 regions, such as the T zone (the forehead; once), the eye rims, the nasolabial fold portions, the U zone (the left; once), and the sides of the mouth (the portion below the lips; once) a total of 5 times to measure the skin state of the user.
[0055]In addition, the user or the sales clerk may capture an image of the face of the user using a dedicated camera or a camera provided in the skin measurement device 50, and may measure the size of the face of the user based on vision recognition technology.
[0056]For example, the skin measurement device 50 may measure the skin state of the user using a speckle-technology-based contact-type skin state measurement method, and may measure 3D facial contours based on vision recognition technology.
[0057]The speckle-technology-based contact-type skin state measurement method, which is technology of capturing a speckle pattern caused by the optical interference phenomenon of a laser to analyze a skin surface state, may measure a total 7 factors, such as wrinkles, pores, freckles, tones, oiliness, moisture, and elasticity. The speckle-technology-based contact-type skin state measurement method is more effective than other skin state measurement methods in that it is possible to measure elasticity.
[0058]Meanwhile, the skin measurement device 50 may transmit measurement values to the hydrogel discharge device 100 and another device over a wireless network, such as Bluetooth or Wi-Fi.
[0059]In addition, the skin measurement device 50 may sort skin states determined based on the measured numerical values, and may map the same with a solution.
[0060]Alternatively, the hydrogel discharge device 100 may determine skin states based on the received skin state information, and may map the same with a solution.
[0061]For example, upon determining that dryness of the measured skin is serious, the skin measurement device 50 or the hydrogel discharge device 100 may set a moisturizing capsule for receiving a moisturizing-ingredient-reinforced material as a solution.
[0062]In addition, in the case in which the size value of the face is determined, the skin measurement device 50 or the hydrogel discharge device 100 may divide the face into five equal regions, and may map each region with a solution.
[0063]For example, upon determining that insufficiency of moisture in the T zone is serious, the skin measurement device 50 or the hydrogel discharge device 100 may set a moisturizing capsule as a solution for the T zone.
[0064]Meanwhile, the skin measurement device 50 or the hydrogel discharge device 100 may provide a solution pertaining to the measurement result through visual/vocal feedback, such as a message “introduce three moisturizing capsules, one elasticity capsule, and one wrinkle treatment capsule.”
[0065]For example, visual feedback may be provided through a display provided in the skin measurement device 50, the hydrogel discharge device 100, or a user's smartphone, or vocal feedback may be provided through a speaker provided therein.
[0066]Meanwhile, referring to FIG. 2b, in a shop, state diagnosis and consultation pertaining to the size, shape, and skin type of the user′ face may be performed based on the skin state information of the user's face 10 measured by the skin measurement device 50.
[0067]The skin measurement device 50 may directly transmit skin state information to a predetermined electronic device, such as a tablet PC 70, or may upload the same in a predetermined server.
[0068]In this case, the predetermined electronic device, such as the tablet PC 70, may use the skin state information measured by the skin measurement device 50.
[0069]Consequently, a customer who uses service in a shop may immediately confirm measurement results and a solution customized for the customer.
[0070]In addition, when necessary, the customer may receive the measurement information through an individual smartphone of the customer.
[0071]Consequently, the beauty system including the hydrogel discharge device 100 according to the embodiment of the present invention is capable of measuring the skin state of principal regions of the user's face 10 using the skin measurement device 50 and providing real-time individually customized care through scientifically measured skin state information.
[0072]Referring to FIG. 2c, a plurality of capsules 210 each containing various ingredients may be introduced into the hydrogel discharge device 100 according to the embodiment of the present invention, and the ingredients in the capsules 210 may be mixed to manufacture a mask pack 11.
[0073]For example, a user at home or a sales clerk may introduce customized capsules for moisturizing, elasticity increase (anti-wrinkles), nourishment, whitening, and trouble alleviation into the hydrogel discharge device 100 depending on the skin type and/or the skin state of the user on that day to manufacture a mask pack 11.
[0074]Consequently, the hydrogel discharge device 100 according to the embodiment of the present invention may be a premium beauty device capable of performing face measurement and providing a solution suitable for each skin region using a 3D printer.
[0075]The 3D printer, which is a device for manufacturing a three-dimensional article based on three-dimensional drawing data, is mainly classified as a stacking-type printer or a cutting-type printer. The stacking-type printer is of a type in which a predetermined material is sprayed to stack a plurality of layers each having a minute thickness, and the cutting-type printer is of a type in which a material is cut to manufacture an article. In the case in which the cutting-type printer is used, material loss occurs. For this reason, the stacking-type printer tends to be used more frequently.
[0076]In this specification, a description is given based on a stacking-type method, although the present invention is not limited to a 3D printing method.
[0077]The hydrogel discharge device 100 according to the embodiment of the present invention may be a kind of 3D printer capable of receiving skin state information and manufacturing a mask pack 11 optimized for the skin state information using hydrogel.
[0078]Meanwhile, the hydrogel discharge device 100 according to the embodiment of the present invention may manufacture a mask pack 11 using a dosage form customized for each region depending on the measured face skin state information of the user.
[0079]For example, when the skin measurement device 50 transmits the skin state information of the five regions, such as the T zone, the eye rims, the nasolabial fold portions, the sides of the mouth, and the U zone, to the hydrogel discharge device 100, the hydrogel discharge device 100 may mix ingredients customized for the respective regions based on the received skin state information with each other to manufacture a mask pack 11.
[0080]Capsules containing hydrogel dosage forms having various ingredients may be introduced into the hydrogel discharge device 100, and the hydrogel discharge device 100 may adjust the ingredients contained in the respective capsules and the mixing concentration thereof to manufacture a gel-type mask pack.
[0081]Consequently, it is possible to optimize the size of an individual mask pack and to select a facial region and ingredient mixing concentration.
[0082]In addition, functional customized capsules for moisturizing, anti-wrinkles, nourishment, and trouble alleviation may be introduced depending on the skin state on that day to manufacture a mask pack, whereby it is possible to manufacture a gel-type mask pack in which ingredients optimized for respective facial regions depending on the skin state on that day are mixed with each other.
[0083]Consequently, the beauty system including the hydrogel discharge device 100 according to the embodiment of the present invention is capable of providing an all-in-one esthetic solution, which does not require the purchase or use of additional cosmetics for specific regions, to the user.
[0084]In addition, the beauty system including the hydrogel discharge device 100 according to the embodiment of the present invention is capable of manufacturing a mask pack 11 using ingredients suitable for the state of the user's skin and the respective regions thereof and thus providing a user experience in which the user feels the effects in which the optimized ingredients are rapidly absorbed into the skin, thereby feeling better effects than when visiting a special skin care shop.
[0085]Consequently, the beauty system including the hydrogel discharge device 100 according to the embodiment of the present invention is capable of satisfying the demand of a user who wishes a customized product and service and manufacturing a mask pack such that a customer can experience the manufacturing process, rather than simply through an industrial process for controlling hydrogel, thereby improving the emotional quality experienced by the consumer (user).
[0086]Meanwhile, referring to FIGS. 2d and 2e, in the shop, a plurality of mask packs may be manufactured and provided in the form of a care package pack 30.
[0087]For example, a user who receives a weekly care package pack 30 may receive customized care using mask packs 31 in the package pack during the week, and may again visit the shop in order to manufacture new mask packs depending on the latest skin state information.
[0088]Hereinafter, the hydrogel discharge device 100 according to the embodiment of the present invention will be described in detail with reference to the drawings.
[0089]FIGS. 4 to 6 are conceptual views showing the hydrogel discharge device according to the embodiment of the present invention, and FIG. 7 is a block diagram showing the hydrogel discharge device according to the embodiment of the present invention.
[0090]Referring to FIGS. 4 to 7, the hydrogel discharge device 100 according to the embodiment of the present invention may include a capsule introduction unit 200, into which a plurality of capsules each receiving a hydrogel dosage form is introduced, a dosage form transfer unit 300 including a plurality of channels 310, along which the hydrogel dosage forms received in the capsules move, a dosage form spray unit 400 for discharging the hydrogel dosage forms supplied from the dosage form transfer unit 300, and a dosage form solidification unit 500 for solidifying the hydrogel dosage forms discharged from the dosage form spray unit 400.
[0091]In addition, the hydrogel discharge device 100 according to the embodiment of the present invention may include a case 101, which defines the external appearance thereof, and the capsule introduction unit 200, the dosage form transfer unit 300, the dosage form spray unit 400, the dosage form solidification unit 500, and other parts may be disposed in the case 101.
[0092]In addition, a cavity, which is a space into which the hydrogel dosage forms are discharged to form a mask pack, may be defined in the case 101.
[0093]Meanwhile, at least a portion 105 of the case 101 may be made of a transparent material, such as glass, such that the interior of the cavity is visible.
[0094]For example, the case 101 may be divided into an upper opaque region and a lower transparent region.
[0095]In this case, the capsule introduction unit 200 may be disposed so as to correspond to the opaque region of the case 101, and the dosage form solidification unit 500 may be disposed so as to correspond to the transparent region of the case 101.
[0096]In addition, a portion of each of the dosage form transfer unit 300 and the dosage form spray unit 400 may be disposed so as to correspond to the opaque region of the case 101, and the remaining portion of each of the dosage form transfer unit 300 and the dosage form spray unit 400 may be disposed so as to correspond to the transparent region of the case 101.
[0097]In addition, the entirety of the transparent region 105 may be formed as a door capable of being opened and closed, or a portion of the transparent region 105 may be formed as a door such that the manufactured mask pack is easily removed. Alternatively, an opening, through which the manufactured mask pack is removed, may be formed in the transparent region 105.
[0098]Meanwhile, a plurality of capsules each receiving a hydrogel dosage form constituting the material for a mask pack may be introduced into and located in the capsule introduction unit 200. Consequently, the capsule introduction unit 200 may also be referred to as a capsule location unit or a capsule introduction/location unit.
[0099]The capsules may receive various ingredients used to manufacture a mask pack. Preferably, the respective capsules receive different ingredients.
[0100]In addition, the capsule introduction unit 200 may be provided with a plurality of introduction ports 220, through which the capsules are introduced and located. The number, size, and shape of the introduction ports 220 may be changed depending on the number, size, and shape of the capsules.
[0101]For example, in the case in which seven dosage capsules are used to manufacture seven mask packs, the height and size of the capsule introduction unit 200 and the height and size of the introduction ports 200 may be set in order to secure sufficient space to receive the seven dosage capsules in consideration of the height of the capsules.
[0102]In addition, the capsule introduction unit 200 may include a plurality of introduction ports 220, and the introduction ports may correspond to the channels in a one-to-one manner.
[0103]In the case in which five capsules are introduced to manufacture a mask pack, five introduction ports 220 may be provided. In the case in which six capsules are introduced to manufacture a mask pack, six introduction ports 220 may be provided.
[0104]The number of channels 310 may also be equal to the number of introduction ports 220 of the capsule introduction unit 200, and the channels 310 may correspond to the respective introduction ports 220 of the capsule introduction unit 200, through which the capsules are introduced.
[0105]FIG. 6 shows an example in which five exclusive channels 310a, 310b, 310c, 310d, and 310e are connected to five capsules 210a, 210b, 210c, 210d, and 201e, respectively.
[0106]Meanwhile, although the channels 310 are briefly shown in FIGS. 4 and 5, the channels 310 may be realized in the form in which the channels 310a, 310b, 310c, 310d, and 310e are coupled to each other. Alternatively, as shown in FIG. 6, the channels 310a, 310b, 310c, 310d, and 310e may be realized so as not contact each other along a considerable portion of the length thereof.
[0107]It is more effective to provide the introduction ports 220 and the channels 310 so as to correspond to the respective capsules in terms of sanitation and management.
[0108]Meanwhile, each of the introduction ports 220 may be configured to have a lateral introduction structure. More preferably, however, each of the introduction ports 220 is configured to have an upper vertical introduction structure in order to achieve easy discharge and to prevent the accumulation of liquid.
[0109]The hydrogel discharge device 100 may be designed such that the cavity, in which a mask pack is manufactured, is sufficiently secured, in addition to the height and size of the capsule introduction unit 200.
[0110]In addition, in consideration of the fact that the hydrogel discharge device 100 is installed and used on a display stand in a shop or on a dressing table at home, the height of the display stand or the dressing table may also be considered.
[0111]For example, the height of the hydrogel discharge device 100 may be designed such that the sum of the height of a general display stand or dressing table and the height of the hydrogel discharge device 100 is smaller than the average height of women, whereby it is possible for a user to easily introduce and recognize capsules.
[0112]Meanwhile, an upper plate 102 of the case 101 may be formed so as to be opened and closed in order to introduce capsules, or at least a portion of the capsule introduction unit 200 may protrude.
[0113]Meanwhile, the capsule introduction unit 200 may include a capsule heating unit 250 for heating the hydrogel dosage forms received in the capsules to liquefy the hydrogel dosage forms and a pushing unit for moving the liquefied hydrogel dosage forms to the dosage form transfer unit 300. Consequently, the dosage forms received in the capsules may be liquefied and moved.
[0114]For example, the capsule heating unit 250 of the capsule introduction unit 200 may include a heat source constituted by one or more hot wires, and the hot wires may be disposed so as to correspond to the respective introduction ports.
[0115]The capsule introduction unit 200 may drive the hot wires to liquefy the hydrogel dosage forms received in one or more of the introduced capsules.
[0116]The capsule introduction unit 200 may heat the lower parts of the capsules at about 60 degrees using the hot-wire-type heating unit 251 to liquefy the hydrogel dosage forms, and may push the capsules so as to push the dosage forms to the outside.
[0117]Meanwhile, the capsule introduction unit 200 may sense whether the capsules are correctly located, and may inform the user of the result of sensing through an output unit 170.
[0118]In addition, in some embodiments, the capsule introduction unit 200 may be configured to automatically recognize the kind of the introduced capsules.
[0119]Meanwhile, the dosage form transfer unit 300 may include a channel heating unit 320 for heating the channels 310 and a pneumatic pressure adjustment unit 330 for adjusting the pneumatic pressure in the channels 310.
[0120]For example, the channel heating unit 320 of the dosage form transfer unit 300 may include a heat source constituted by one or more hot wires 321, and the hot wires 321 may be disposed so as to correspond to the respective channels 310a, 310b, 310c, 310d, and 310e.
[0121]The dosage form transfer unit 300 may drive the hot wires 320 to maintain the temperature in the channels 310 at about 60 to 66 degrees such that the liquefied dosage forms are moved while the viscosity and liquid state thereof are maintained.
[0122]The pneumatic pressure adjustment unit 330 of the dosage form transfer unit 300 may adjust the pneumatic pressure in the channels 310, and may pump the channels 310 at a high pressure when necessary. To this end, the pneumatic pressure adjustment unit 330 may include a pump unit 331, and the pneumatic pressure in the channels 310 may be adjusted through pumping of the pump unit 331.
[0123]The dosage form spray unit 400 may include a nozzle 410 for discharging the hydrogel dosage forms supplied from the dosage form transfer unit 300.
[0124]In some embodiments, the nozzle 410 may include a plurality of introduction ports and spray ports corresponding to the channels 310. In order to increase the manufacturing speed and to maintain sanitation, a plurality of individual introduction ports 220 and nozzles 410 may be provided in the device 100. In addition, the nozzle 410 may include a plurality of introduction ports and spray ports such that the nozzle functions as a plurality of individual nozzles.
[0125]In addition, the dosage form spray unit 400 may include an arm 420 for moving the nozzle 410, and one or more motors for moving the arm 420 in a predetermined direction may be provided.
[0126]The dosage form spray unit 400 may spray the hydrogel dosage forms moved through the channels 310 to the outside in order to manufacture a mask pack.
[0127]For example, the dosage form spray unit 400 may be a dispensing-type 3D discharger for performing 3D printing in a fused deposition modeling (FDM) mode. The fused deposition modeling (FDM) mode is a mode in which a solid material is liquefied immediately before being sprayed such that an article is manufactured so as to have a stacked structure. The dosage form spray unit 400 may spray hydrogel to manufacture a mask pack.
[0128]In addition, the fused deposition modeling (FDM) mode is a mode in which the arm 420 is moved. An FDM delta mode, which is visualized and is executed at high speed, may be used such that the user experiences the mask pack manufacturing process.
[0129]In a standby state before spraying, the Delta-Bot arm 420 may move downwards along the Z axis, and in the working state, the Delta-Bot arm 420 may move along the X axis and the Y axis to move the nozzle 410.
[0130]In the embodiment of the present invention, the dosage form spray unit 400 adopts the FDM delta mode, in which visualization is excellent. At the time of manufacturing a mask pack, the nozzle 410 moves downwards to dispense hydrogel to the surface of a discharge plate 510 of the dosage form solidification unit 500 according to the operation of the Delta-Bot arm 420. In addition, after dispensing of hydrogel is completed, the nozzle 410 may move upwards according to the operation of the Delta-Bot arm 420.
[0131]Meanwhile, the dosage form spray unit 400 may include a nozzle heating unit 430 for heating the hydrogel dosage forms supplied from the dosage form transfer unit 300 such that the temperature of the nozzle 410 is maintained at 60 to 75 degrees.
[0132]The dosage form spray unit 400 may divide the discharge surface of the discharge plate 510, to which dosage forms are discharged, into a plurality of regions, and may sequentially discharge the hydrogel dosage forms supplied from the dosage form transfer unit 300 to the divided regions.
[0133]That is, the dosage form spray unit 400 may sequentially move the nozzle 400 above the regions such that a required ingredient is discharged to a certain region and the nozzle then moves to the next region.
[0134]In addition, the dosage form spray unit 400 may sequentially discharge the hydrogel dosage forms supplied from the dosage form transfer unit 300 depending on the ingredients of the hydrogel dosage forms.
[0135]According to the present invention, various ingredients received in a plurality of capsules may be combined to manufacture a mask pack.
[0136]In this case, the dosage form spray unit 400 may discharge a predetermined amount of an ingredient in one of the capsules, and may then discharge a predetermined amount of another ingredient in the next capsule.
[0137]The dosage form solidification unit 500 may include a discharge plate 510, on which the hydrogel dosage forms discharged from the dosage form spray unit 400 are stacked.
[0138]Meanwhile, the front lower-end unit of the hydrogel discharge device 100, i.e. the dosage form solidification unit 500, may be formed in an opening-and-closing-type structure in which it is easy to separate a mask pack.
[0139]In addition, the discharge plate 510, on which the dosage forms are discharged and stacked to manufacture a mask pack, may be located at the lowermost end of the hydrogel discharge device 100.
[0140]Meanwhile, in some embodiments, the dosage form solidification unit 500 may include a discharge plate heating unit 520 for heating the hydrogel dosage forms discharged from the dosage form spray unit 400.
[0141]In the case in which the fluidity of the dosage forms is not high and the gelation of hydrogel is possible at room temperature, a heating or cooling element may not be disposed in the dosage form solidification unit 500. In this case, however, temperature variability is high, and quality variability is also high.
[0142]In the case in which a cooling element is disposed in the dosage form solidification unit 500 of the hydrogel discharge device 100 in order to rapidly cool and solidify the hydrogel dosage forms for rapid manufacture, the formerly discharged dosage form and the latterly discharged dosage form may be separated from each other.
[0143]Consequently, the temperature in the dosage form solidification unit 500 may be maintained within the range of 50 to 100 degrees in order to maintain the dosage forms in a liquid state for a predetermined time, whereby an interfacial separation problem may be solved.
[0144]In the case in which a heating element is used, a heat loss speed is lower than in the case in which a cooling element is operated. Consequently, heat-transfer-solidified-contour dosage forms may be possible, whereby the joined surfaces of the dosage forms may melt, and interfacial separation problem may be partially solved. In addition, when the dosage forms permeate, the fluidity of the dosage forms may be maintained and the dosage forms may permeate into an empty space, whereby an empty interface space may be minimized.
[0145]More preferably, the dosage form solidification unit 500 includes a heating element and a cooling element in order to sequentially perform a heating process and a cooling process.
[0146]The hydrogel discharge device 100 according to the embodiment of the present invention may further include a communication unit 160 for receiving skin state information from an external electronic device. For example, the communication unit 160 may receive the skin state information from the skin measurement device 50 or a predetermined server.
[0147]To this end, the communication unit 160 may include a wireless Internet module for wireless Internet access and/or a short-range communication module for short-range communication.
[0148]The wireless Internet module is configured to transmit and receive a wireless signal over a communication network based on wireless Internet technologies.
[0149]For example, the wireless Internet technologies may include WLAN (Wireless LAN), Wi-Fi (Wireless-Fidelity), Wi-Fi (Wireless Fidelity) Direct, DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband), WiMAX (World Interoperability for Microwave Access), HSDPA (High-Speed Downlink Packet Access), and HSUPA (High-Speed Uplink Packet Access). The wireless Internet module transmits and receives data based on at least one wireless Internet technology within a range including unspecified Internet technologies.
[0150]In addition, the short-range communication module may support short-range communication using at least one of Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra-Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, or Wireless USB (Wireless Universal Serial Bus).
[0151]The short-range communication module may support wireless communication between the hydrogel discharge device 100 and another electronic device or a network over wireless area networks. The wireless area networks may be wireless personal area networks.
[0152]Here, another electronic device may be the skin measurement device 50, a wearable device, or a head-mounted display that is capable of exchanging data with (or that is capable of being operatively connected to) the hydrogel discharge device 100 according to the present invention.
[0153]The short-range communication module may sense (or recognize) an electronic device that is located adjacent to the hydrogel discharge device 100 and is capable of communicating with the hydrogel discharge device 100. Furthermore, in the case in which the sensed electronic device is a certified device capable of communicating with the hydrogel discharge device 100 according to the present invention, a processor 150 may transmit at least a portion of the data processed by the hydrogel discharge device 100 to an external electronic device through the short-range communication module. Consequently, the user of the external electronic device may use the data processed by the hydrogel discharge device 100.
[0154]The hydrogel discharge device 100 according to the embodiment of the present invention may further include a processor 150 for controlling the overall process of manufacturing the mask pack.
[0155]The processor 150 may control the respective units in the hydrogel discharge device 100, such as the capsule introduction unit 200, the dosage form transfer unit 300, the dosage form spray unit 400, and the dosage form solidification unit 500.
[0156]In addition, the processor 150 may control the kind or amount of the hydrogel dosage form to be moved to the dosage form transfer unit 300, among the hydrogel dosage forms received in the capsules.
[0157]That is, the processor 150 may set the kind of ingredients that are used to manufacture a single mask pack and the mixing concentration thereof, among various dosage-form ingredients introduced as raw material, and may control the respective units in the hydrogel discharge device 100 such that the mask pack is manufactured based on the settings.
[0158]The processor 150 may control the kind or amount of the hydrogel dosage form to be moved to the dosage form transfer unit 300, among the hydrogel dosage forms received in the capsules, based on the skin state information received through the communication unit 160.
[0159]Meanwhile, the processor 150 may control the respective units in the hydrogel discharge device 100, such as the capsule introduction unit 200,
