Description

Skin care apparatus

The present invention relates to a skin care device, and more particularly, to a skin care device that enables transdermal administration of vitamins using ultrasonic cleaning and electrophoresis in one device.

Ascorbic acid, commonly known as vitamin C, has the effect of keeping the skin healthy and attractive. In addition to preventing, it is known to have an effect of inhibiting oxidation of fat and preventing skin damage caused by solar ultraviolet rays.

Ascorbic acid is also known to have the effect of inhibiting the production of histamine, which is thought to be the cause of melanin formation and various allergies, especially those with sensitive skin, that induce pigmentation of the skin.

Therefore, attempts have been made to use ascorbic acid as an active substance in cosmetics and pharmaceuticals that have a whitening effect such as elimination of blemishes and freckles and an anti-wrinkle effect.

Ascorbic acid is administered to the human body as a method of oral administration and transdermal administration method. As oral administration method uses ascorbic acid in the form of powder, it is possible to store and use ascorbic acid in a relatively stable form. Since the process of delivery to the skin is inefficient, there is a problem that the actual efficiency, which is the ratio of the active substance substantially penetrating the skin to the total dosage, is very low.

In order to increase the efficiency, transdermal administration method that directly administers ascorbic acid to the skin is preferred, but ascorbic acid itself has low transdermal administration efficiency, and ascorbic acid has very low solubility in nonaqueous medium. It is not practical, and dissolution of ascorbic acid in an aqueous medium has high solubility, but it is not practical because ascorbic acid is easily oxidized and loses its inherent function.

In order to improve the instability of ascorbic acid, U.S. Patent No. 4,983,382 proposed a method of using water and an organic solvent such as ethanol as a medium, and U.S. Patent No. 5,981,578 is a non-aqueous solution containing ascorbic acid. He also proposed a method of simultaneously applying other products to the skin, such as lotion or lotion containing a solution and water.

As another method for improving the instability of ascorbic acid, a method of stabilizing ascorbic acid by forming a derivative by combining another compound with ascorbic acid is known.

For example, Korean Patent Application No. 97-23005 is useful for synthesizing ascorbic acid derivatives having excellent stability and safety by reacting L-ascorbic acid with 3-aminopropane phosphoric acid, and using the ascorbic acid derivative as an active ingredient. Cosmetic formulations such as lotions, nourishing creams, massage creams, essences, etc. are disclosed, but even when transdermal administration of ascorbic acid is mixed with cosmetics, the skin delivery process is inefficient, resulting in low practical efficiency.

In order to solve the above problems, Korean Patent Application No. 2000-21350 filed by the present applicant provides a method for transdermal administration of ascorbic acid.

Accordingly, it is an object of the present invention to provide a skin care device to facilitate the transdermal administration of ascorbic acid.

In order to achieve the above object, the skin care device of the present invention includes a power source to which AC power is input; A processor unit operated by a direct current supplied from the power supply unit and controlling an oscillation width, time, and iontophoretic current amount; A resonator unit connected to the power unit in alternating current and resonating by ultrasonic waves; An amplifier for amplifying the resonated pulses; It comprises an electrophoretic vibration unit which is connected to the amplification unit and the electrophoretic vibration to enable the electrophoresis and ultrasonic cleaning in the state in contact with the skin by the vibration plate is generated by the piezoelectric element attached to the surface.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram showing the configuration of a skin care device according to the present invention.

AC power is applied to the power supply unit 10, and the applied AC power is converted into AC or DC and input to a processor unit or a resonance unit described later.

The processor 20 is operated by the DC power input through the power supply unit 10, and controls the oscillation width of the pulse, the control of the interruption time, and the iontophoretic current amount.

In addition, the LED processor 22 and the switch 24 are connected to the processor unit 20 so that the level of work progress by level by ultrasonic cleaning or electrophoresis of the skin and the current skin care step can be checked.

The resonator 30 includes a coil and a condenser, and when the frequency of the power source and the predetermined natural frequency coincide with each other, a resonance phenomenon occurs.

At this time, the maximum frequency of the resonance is amplified by the amplifier 40 so that the frequency is about 20 kHz to 40 kHz, and more preferably, the frequency of 28 kHz.

The electrophoretic vibrating unit is divided into the electrophoretic unit 50 and the vibrating unit 60 and the contact plate 72 is energized with the amplifying unit 40 inside the case 70 as shown in FIGS. 2 and 3. Share.

Since the contact plate 72 is a part in contact with the human body, it is made of stainless steel which is harmless to the human body and has good contact feeling.

In particular, a coating film made of titanium nitride (TiN) is formed at the tip of the contact plate 72, that is, the portion in direct contact with the human body, to prepare for skin having an allergic reaction sensitive to metal.

The coating film may be deposited using a chemical vapor deposition method used in a semiconductor process or by a sputtering method.

The upper and lower surfaces of the contact plate 72 attach an aluminum plate 76 to which the piezoelectric element 74 is fixed, as shown in FIG. 3, which aluminum plate can be replaced with duralumin.

The circuit for electrophoresis is connected to the contact plate made of stainless steel, and the circuit for ultrasonic cleaning is connected to the piezoelectric element 74.

As a result, the ultrasonic cleaning can be performed independently, and electrophoresis and ultrasonic cleaning can be performed simultaneously.

The contact plate 72 is capable of energizing the ground portion 78 proposed in accordance with another feature of the present invention, which flows from the power supply portion 10 to the contact plate 72 by energization of the ground portion 78. A current of one pole is delivered to the contacted skin to reach another pole that flows through the handheld ground portion 78 to form a circuit.

At this time, the poles of the power supply unit 10 and the ground unit 78 may be used as either positive voltage / negative voltage or negative voltage / positive voltage.

On the other hand, a sponge cover 80 may be fitted to the tip portion of the contact plate 72, which is used to infiltrate the skin with transdermal doses such as drugs, cosmetics, or ascorbic acid by iontophoresis.

That is, the sponge cover 80 is inserted into the front end of the contact plate 72 and the aqueous solution is absorbed into the sponge cover 80 by soaking the front end of the contact plate 72 in the ascorbic acid aqueous solution. Youngdong's work begins.

It is preferable to form fitting grooves on both side surfaces of the tip end of the contact plate 72 so that the sponge cover 80 can be firmly fitted to the tip end of the contact plate 72.

By using the skin care device of the present invention configured as described above, it is possible to manage the skin in four modes.

The four skin care modes are the cleansing mode, the scaling mode, the vitamin mode and the lifting mode. The cleansing mode and the peeling mode are ultrasonic modes. Vitamin mode and lifting mode are modes that use ultrasound and electrophoresis simultaneously.

First, after supplying power to the power supply unit 10, if the purification mode is selected, the processor 20 controls the ultrasonic vibration width and the operating time corresponding to the purification mode.

Accordingly, the resonance is made in the resonator unit 30 and the vibration is between 20 kHz and 40 kHz with a weak vibration width, and the contact plate 72 also vibrates as the proposed piezoelectric element 74 vibrates according to the characteristics of the present invention.

Subsequently, the bottled water is applied in an appropriate amount so as not to cloud the skin, the tip of the contact plate is maintained at 45 ° on the skin surface, and the operation of rubbing while keeping the tip of the contact plate close to the skin is performed for 5 minutes.

In the exfoliation mode, vibrations between 20 kHz and 40 kHz of strong amplitude are rubbed into the transderm for 5 minutes.

Next, the vitamin mode simultaneously generates a positive voltage of 3 to 20v to a 60 Hz pulse and a negative voltage of 3 to 20v to a 500 Hz pulse to simultaneously apply a current of 0.01 to 1.0 mA / cm 2 to the transdermal skin and simultaneously generate ultrasonic vibration. It is preferable to apply a vibration between 23 kHz and 40 kHz to the transdermal about 10 minutes with a period of 1 Hz to 100 Hz.

Here, if the voltage is greater than 20v, hypersensitivity may be caused by chlorine or a medicament of the skin epidermal layer. If the voltage is less than 3v, the ascorbic acid phosphate metal salt may not form electrical energy enough to penetrate the cell membrane of the epidermal layer.

When the vitamin mode is implemented, a sponge cover 80 is placed on the tip of the contact plate 72, and the ascorbic acid aqueous solution is flipped over the sponge cover 80 for use.

At this time, since the electrophoresis and the vibration is used, the iontophoretic administration and the ultrasonic massage function can be simultaneously taken.

In particular, when the ground portion 78 is held firmly by hand, ascorbic acid penetrates into the skin with an electric current.

Finally, in the lifting mode, the moisturizer is evenly applied to the entire skin and applied to the transdermally for 5 minutes with a vibration between 23 kHz and 40 kHz in a period of 0.01 to 1.0 mA / cm 2 and 1 Hz to 100 Hz. At this time, the ultrasonic massage and the most ideal form of frequency relaxes and stiffens the skin muscle, giving the maximum massage effect.

As described above, the ascorbic acid composition is penetrated into the percutaneous body using the skin care device of the present invention to remove blemishes, blemishes, freckles, wrinkles, acne, sebum, skin aging, and whitening. can see.

In addition, electrophoresis may be performed in combination with the ultrasonic cleaning prior to transdermal administration of ascorbic acid, thereby achieving a synergistic effect on skin beauty.
