Definitions
- the present invention relates to a beauty method for skin beauty.
- the pack agent is configured to remove skin dirt, wastes, and the like together with the used pack agent.
- a method for removing the used pack agent from the skin a method of wiping with cotton or the like, or washing off with warm water or the like is common. Recently, a method for removing a used pack agent more easily than these general methods is desired.
- Patent Document 1 proposes a skin cleaning cream in which a powder composed of magnetized particles or particles that can be magnetized is contained in an excipient that serves as a coating base material.
- This skin cleaning cream is used, for example, as follows. That is, after applying the skin cleaning cream to the skin, a magnet or the like is brought close to the skin cleaning cream on the skin surface. Thereby, magnetic force acts on the powder contained in the skin cleaning cream, and the powder is attracted by the magnetic force. Along with the powder, used skin-cleaning cream and skin dirt adhering to the powder are adsorbed and removed from the skin surface. In this way, the skin cleaning cream is easily removed from the skin surface.
- Patent Document 2 discloses a method for promoting penetration of a cosmetic ingredient by ion introduction. Ion introduction is a method that promotes the penetration of cosmetic ingredients into the skin by moving a charged cosmetic ingredient toward the inside of the skin by passing a weak current through a site where the cosmetic ingredient is desired to penetrate.
- a conventional pack containing magnetic powder uses an excipient mainly composed of an oil component such as petrolatum. Therefore, after the pack agent is adsorbed and removed from the skin by magnetic force, at least a part of the oil component remains on the skin surface, and an oil film is formed on the skin surface. And since the said oil film is insulating, it is difficult to flow the weak electric current for ion introduction
- an oil component such as petrolatum
- the present invention has been made in view of the above background, and intends to provide a beauty method capable of obtaining an excellent beauty effect by a simple operation.
- One aspect of the present invention is the step of applying to the skin an aqueous pack containing water, magnetic powder, a thickener, and a charged iontophoretic component; Applying magnetic force to the magnetic powder in the aqueous pack applied to the skin, adsorbing and removing the magnetic powder from the skin surface while leaving the aqueous solution of the iontophoretic component on the skin surface; And a step of causing an iontophoretic current to flow through the skin on which the aqueous solution is disposed to allow the iontophoretic component to penetrate into the skin.
- the step of applying the aqueous pack agent to the skin is performed.
- the water-based pack agent contains water, magnetic powder, and a thickener. Therefore, in the aqueous pack agent, the magnetic powder is dispersed to form a paste suitable for application to the skin, and exhibits a smooth touch when applied to the skin.
- a step of applying a magnetic force to the magnetic powder in the aqueous pack applied to the skin to adsorb and remove the magnetic powder from the skin surface is performed.
- the magnetic powder is adsorbed and removed from the skin surface by a magnetic force, and used water-based pack agent and skin dirt attached to the magnetic powder are adsorbed and removed from the skin surface.
- the aqueous pack agent is aqueous, it hardly forms an oil film on the skin surface after the used aqueous pack agent is adsorbed and removed. Therefore, the skin surface after adsorbing and removing the water-based pack agent is in a state in which there are few substances that inhibit the penetration of cosmetic components such as dirt on the skin, waste products, or oil films, and the cosmetic components are likely to penetrate. Since the aqueous pack agent contains an ion introduction component in advance, the aqueous pack agent is adsorbed and removed from the skin surface, and an aqueous solution containing the ionized ion introduction component is applied to the skin surface.
- an ion introduction current is passed through the skin to which the aqueous solution is applied to cause the ion introduction component to penetrate into the skin.
- the water-based pack agent hardly forms an oil film on the skin surface after adsorption removal. Therefore, after the water-based pack agent is adsorbed and removed from the skin surface, an ion introduction current can be passed through the skin without performing an operation of removing the oil film. Accordingly, the charged iontophoretic component can be moved toward the inside of the skin, and the penetration of the iontophoretic component into the skin can be promoted.
- the above cosmetic method applies a water-based pack agent to the skin and applies a solution that adsorbs and removes dirt on the skin by a series of operations of adsorbing and removing by magnetic force, and applying an aqueous solution containing an iontophoretic component to the skin.
- the ion introduction can be performed continuously. Therefore, it is easy to obtain an excellent cosmetic effect by continuously performing removal of skin dirt and the like and ion introduction.
- contamination of skin, and ion introduction an operation

- FIG. The perspective view which looked at the beauty instrument which performs the operation
- the ion introduction is performed by bringing two electrodes into contact with the skin and passing an ion introduction current between the two electrodes.
- a working electrode one of the two electrodes
- a counter electrode one of the two electrodes
- the working electrode is an electrode that is brought into contact with a portion where the iontophoretic component is to penetrate.
- the iontophoretic current is a unipolar current that exhibits various waveforms such as a direct current and a pulse current.
- the polarity of the ion introduction current is determined in accordance with the polarity of the charge of the ion introduction component. For example, when the iontophoretic component is present in the aqueous solution in a negative ion state, a voltage is applied between both electrodes so that the working electrode has a lower potential than the counter electrode. Thereby, an ion introduction current flows between the working electrode as the cathode and the counter electrode as the anode. Then, the ion introduction component receives repulsive force from the working electrode and moves toward the counter electrode side, that is, toward the inside of the skin. As a result, penetration of the iontophoretic component into the skin is promoted.
- the magnitude of the ion introduction current can be set to 100 to 1000 ⁇ A, for example.
- the magnitude of the iontophoretic current is less than 100 ⁇ A, the effect of promoting the penetration of the beauty component into the skin may be insufficient, and the beauty effect that can be experienced may be reduced.
- size of an iontophoresis electric current exceeds 1000 microamperes, the penetration promotion effect of a beauty component begins to be saturated.
- the magnitude of the iontophoretic current is more preferably set to 100 to 240 ⁇ A.
- the properties such as the touch and the ease of elongation at the time of application become the target properties, and the solvent can be appropriately selected so as to exhibit a paste form that can be applied to the skin.
- the water-based pack agent can be configured to contain water as a solvent.
- a charged iontophoretic component is present in the water-based pack agent. Therefore, as described above, after removing the magnetic powder from the skin, an aqueous solution containing an iontophoretic component remains on the skin surface.
- the solvent of the water-based pack agent may be composed only of a water-soluble solvent and may not include water.
- the water-soluble solvent for example, water-soluble alcohols such as ethanol and isopropyl alcohol, glycerin and the like can be used.
- the water-based pack agent contains a component such as ascorbate that is dissolved in water to generate an iontophoretic component.
- the above components remain on the skin surface after the magnetic powder is removed from the skin.
- the above-mentioned components remaining on the skin surface are ionized by moisture contained in the skin itself, moisture in the atmosphere, and the like, and an iontophoretic component is generated. Therefore, ion introduction can be performed even if the water-based pack agent itself does not contain water.
- the water-based pack agent used in the above cosmetic method is less likely to form an oil film on the skin surface as the content of components that do not dissolve in water decreases, and tends to have excellent performance. Therefore, the water-based pack agent regulates the content of components not dissolved in water to 50% by mass or less when the total of components other than the magnetic powder is 100% by mass. Further, from the viewpoint of suppressing the formation of an oil film on the skin surface, the content of the component that does not dissolve in water is preferably 40% by mass or less, and more preferably 30% by mass or less.

In this case, the water-based pack agent is likely to feel rough when it is brought into contact with the skin. In some cases, the water-based pack agent may give an excessively large stimulus to the skin. Therefore, it may be difficult to spread the aqueous pack agent on the skin. Therefore, from the viewpoint of obtaining a water-based pack agent that exhibits a paste suitable for application to the skin, the water content is preferably 5% by mass or more, and more preferably 6% by mass or more.

Accordingly, in order to obtain a water-based pack agent that exhibits a paste suitable for application to the skin, the content of the magnetic powder is preferably 80% by mass or less, more preferably 75% by mass or less, and 70% by mass. The following is more preferable.
- the viscosity of the water-based pack agent is preferably 9000 mPa ⁇ s or more.

- the water-based pack agent may further include a cosmetic component that imparts a cosmetic effect to the skin.
- the water-based pack agent hardly forms an oil film on the skin surface after adsorbing and removing the used water-based pack agent.
