Description

Skin care device for radio frequency electric treatment

The present invention relates to a skin care device including a roller having a plurality of microneedles, a roller base for accumulating the rollers, and a handle part for supporting the roller base. The present invention relates to a skin care device capable of electrotherapy by providing electric stimulation using high frequency in the lower part of the epidermis to promote the production of substances in the human body, such as collagen.

In other words, the skin care device according to the present invention, the roller is provided with a plurality of microneedle, the roller base and the handle portion are all made of a metal body through the electricity, the rear end of the handle portion is configured to be connected to the charge supply device So,

When the skin care device is used while the ground rod or ground pad of the charge supply device is in contact with the human body, the current applied from the charge supply device will form a closed loop via the contact terminal and the human body and the ground rod. The present invention relates to a skin beautifier that stimulates the production of substances in the human body such as collagen by giving electric stimulation using high frequency to the part.

In general, the skin tissue can be divided into epidermal layer (stratum corneum) and dermal layer, and subcutaneous fat, blood vessels are distributed in the subcutaneous fat through the epidermal layer and the dermis layer, the epidermal layer is 0.1mm, the dermal layer has a thickness of 1.5 ~ 5mm.

At this time, the dermal layer related to wrinkles constitutes the bottom layer of the epidermal layer. The collagen in the dermal layer gradually decreases as aging progresses, and as a result, the skin becomes dry and wrinkles increase.

Therefore, in order to prevent the wrinkles or maintain elastic skin, it is necessary to continuously replenish the consumed collagen or inject new collagen.

In order to prevent or improve wrinkles or maintain elastic skin, a method such as applying a gel or lotion containing a nutrient such as vitamin C or a peptide necessary for collagen formation or a lotion was applied to the skin.

However, the above method has the disadvantage that the solvent can pass through the epidermal layer of the skin, but only 0.3% of the total content, and the remaining 99.7% does not pass through the outermost sebum of the skin and remains on the skin or disappears. Therefore, the use of solvents to improve wrinkles or give elasticity to the skin was bound to follow.

Therefore, by stimulating the skin or forming microchannels in the skin tissue, it effectively supplies nutrients such as vitamin C and peptides to the dermal layer containing collagen to improve stretch marks and wrinkles, as well as to restore acne scars and burn scars. A skin treatment apparatus (Registration No. 395359 [Microneedle Roller], hereafter referred to as the prior art) has been disclosed.

The skin care device of the prior art constitutes a roller 113 with a disc having a multi-stage stacking structure, and in a state in which the microneedle 114 is radially fitted into an inner surface groove of the multi-stacked disc, One end of the microneedles 114 is configured to be exposed to the outer surface of the roller 113 (see FIG. 5). The microneedles exposed to the outer surface of the roller as well as irritating the skin make microchannels in the epidermal layer, such as vitamin C, peptides, and the like in the dermis. While supplying the same nutrients necessary for collagen formation, collagen is effectively regenerated in the dermal layer to reduce aging skin, while softening the scar tissue while softening the skin surface to promote skin tissue regeneration at the scar area.

However, since the prior art is only dependent on the skin irritation effect by the microneedle, the effect of softening the skin surface and smoothing the scar tissue was expected, but the effect of promoting the regeneration of collagen in the human body to improve wrinkles is satisfactory. There was an unproblematic problem.

The first object of the present invention, while using the skin irritation effect of the microneedle as it is, during the treatment, the current flows through the human skin, giving the electrical stimulation using the high frequency in the lower part of the epidermis to produce substances in the human body, such as collagen It is to facilitate.

In addition, by allowing the current to flow well through the human body without leakage in the middle, there is another purpose to allow the drug transporter to be more effectively delivered into the skin.

On the other hand, in the present invention, the current flows only when the skin care device is used, and the current does not flow when not in use, so that there is another purpose to prevent the overcurrent from being applied to the human body of the user.

The above object is achieved by configuring the roller, the roll base, and the handle part of the skin care device all made of a metal which is a conductive material, and configured to supply current from the charge supply device through a connection terminal provided at the rear end of the handle part.

That is, during use of the skin care device to give the electrical stimulation using the high frequency in the lower part of the epidermis to promote the production of substances in the human body, such as collagen. In addition, high-frequency fever promotes blood circulation in the body.

In addition, the skin care device is provided with a pressure sensor for detecting a state in use, so that the current flows only when the skin care device is used, and the current does not flow when not used. Therefore, it is possible to prevent the overcurrent is applied to the user's human body.
