As a result, the beauty tool 1 can reduce power consumption in a standby state, that is, in a state where at least one of the first electrode 11 or the second electrode 12 is not in contact with the human body.
  • the beauty tool 1 is provided with an LED indicator 14, and the LED indicator 14 is lit during the ion introduction mode. Therefore, the user can easily confirm that the ion introduction mode is being performed by turning on the LED indicator 14. As a result, the beauty tool 1 is easy for the user to use.
  • the beauty tool 1 has a vibration motor 15 at the end on the first electrode 11 side, and is configured such that the vibration motor 15 is driven during the ion introduction mode. Therefore, the vibration generated from the vibration motor 15 causes effects such as improvement of lymph flow, blood circulation, and improvement of metabolism at the contact portion between the first electrode 11 and the skin and its peripheral portion. May be obtained. As a result, the beauty tool 1 can further improve the beauty effects that can be experienced.
  • the first electrode 11 and the second electrode 12 are disposed so as to be positioned on opposite sides in the vertical direction as shown in FIGS. Therefore, when the beauty tool 1 is placed on a desk or the like, the possibility that the first electrode 11 and the second electrode 12 are conducted through the placement surface can be reduced, and the power consumption can be easily reduced.
  • the example which makes the 1st electrode 11 and the skin surface which wants to acquire a cosmetic effect contact is shown in the said Example and the 1st electrode 11 is functioned as a working electrode in iontophoresis mode, the 2nd electrode 12 was act
  • An electrode configuration is also possible.
  • the voltage applied between the first electrode 11 and the second electrode 12 can also be set as appropriate according to the composition of the cosmetic component. For example, when the cosmetic component desired to be introduced into the skin is a cation, the potential of the first electrode 11 may be set higher than that of the second electrode 12 in the ion introduction step S8.
  • a cosmetic agent that exhibits other cosmetic effects can also be used.
  • the beauty agent for example, various agents such as one having an action of removing dirt and waste on the skin and one containing a beauty component different from the beauty component can be used.
  • the cosmetic agent may include a cosmetic component having a charge described above.
  • the cosmetic agent may be capable of being adsorbed by magnetic force.
  • the beauty agent can be easily removed by the suction head portion 13 of the beauty tool 1. That is, after applying the cosmetic agent, the user protrudes the suction head portion 13 from the hand and grips the first electrode 11 side of the main body portion 10, and holds the magnetic force generating surface 130 side of the suction head portion 13 on the skin. Move closer to. Thereby, the used beauty agent is easily removed from the skin by the magnetic force of the magnetic force generating surface 130 and is adsorbed by the adsorption head unit 13.
  • a cosmetic component that is charged in advance is contained in a cosmetic agent that can be adsorbed by magnetic force
  • the cosmetic agent can be removed while the cosmetic component remains on the skin surface when the adsorption head unit 13 is brought close to the skin.
  • a removable cover member can be attached to the magnetic force generating surface 130 in advance.
  • various shapes and materials can be used without being limited in shape and material.
  • the used beauty agent adsorbed by the adsorption head unit 13 can be peeled off from the magnetic force generation surface 130 together with the cover member and discarded.
  • the beauty instrument 1 of this example has the microcomputer 30 for control provided with the contact head 13 and the contact detection function of an electrode and skin as an additional function, the beauty instrument which does not have these functions Even so, it goes without saying that an improvement in the beauty effect can be expected by controlling the current waveform applied to the skin.
  • ⁇ Test product> As the beauty agent used in combination with the beauty tool 1 using the beauty tool 1 of the above example, one having the following composition was used.
  • the beauty agent is obtained by adsorbing and removing the magnetic powder from the skin using the adsorption head unit 13 of the beauty device 1, and then L-ascorbic acid-2-sodium phosphate functioning as an ion-introducing component, a moisturizing agent, and the like. Designed to remain on the surface.
  • ⁇ Test method> Half of the subject's face was treated as the surgical site, and the surgical procedure was performed on the surgical site at the interval of once every 3 days.
  • the cosmetic agent was applied only to the treatment area and allowed to stand for 5 minutes.
  • the magnetic powder in the beauty agent was adsorbed and removed from the skin using the adsorption head unit 13 of the beauty tool 1.
  • the first electrode 11 is brought into contact with the skin while holding the second electrode 12 side of the beauty tool 1, and the ion introduction mode to the treatment part and the skin massage are performed for about 5 minutes to complete the treatment. did.
  • the evaluation of the cosmetic effect by the implementation of the iontophoresis mode is based on the evaluation of the pores of the treatment area and the control area at the time of starting the test, at the time of 2 weeks, at the time of 4 weeks and at the time of 8 weeks (when the test is completed). This was done by visual observation. The results of visual observation were quantified using a visual evaluation scale (Visual Analog Scale, VAS) and a five-step evaluation. The method of quantification by VAS and 5-step evaluation is as follows.
  • VAS The VAS in this evaluation is a scale composed of a line segment having a length of 79 mm.
  • One end point of the VAS corresponds to “a state in which the subject feels that the pores are not bothered”, and the other end point corresponds to “a state in which the subject feels that the pores are very concerned”.
  • Evaluation by VAS is performed by the subject marking the state of his / her pores on the VAS. Then, the ratio of the length from one end point to the mark position with respect to the entire length of the VAS was calculated, and this value was used as the VAS value. That is, the VAS value quantified by the above-described calculation method indicates that the smaller the value, the less likely the pores are concerned.
  • Table 1 shows changes in VAS values over time for each subject.
  • FIG. 9 is a graph in which changes in the VAS values between the start of the test and the completion of the test are plotted for each subject evaluated for the treatment part, and FIG. It is the graph which plotted the change of the VAS value between the time of completion of a test according to a test subject.
  • the horizontal axis in FIGS. 9 and 10 is the VAS value, and the vertical direction corresponds to the subject ID.
  • the VAS value of the treated area decreased with time, and the condition of pores tended to improve with time.
  • the VAS value of the treatment area at the time of completion of the test becomes smaller than the VAS value at the start of the test, and the state of the pores after 8 weeks of treatment Improved significantly.
