Skin stimulator

Abstract

A skin stimulator which can be produced through a simple process in which a circular disc of a drum is formed by integrating a metal disc having needles on a circumferential surface thereof with a reinforcing resin material using insert injection molding and layering a plurality of metal discs and retainers, thus increasing productivity and economic efficiency, realizing stable operation and preventing foreign substances from being jammed in the drum, and which is configured such that, when pricking the skin with the needles, the needles do not give severe damage to the skin and can be prevented from being broken, thus being effectively used for a lengthy period of time, and in which each of the needles forms a polygonal cross-section of at least six sides instead of a circular cross section, so that, when pricking the skin with the needles, the contact surface of each needle relative to the skin can be reduced, thus minimizing the pain.

Description

technical field [0001] In general, the present invention relates to a skin stimulator, and more particularly, to a skin stimulator configured such that a plurality of discs and holders have respective simple structures and are closely fitted to each other, and form a drum , wherein the discs have needles on their peripheral surfaces, the retainer keeps the plurality of discs spaced apart from each other, and in the drum it is possible to prevent the discs and the retainer from being undesirable relative to each other Move smoothly so that the dust falling on the skin will not be squeezed into the roller, and when the skin is pierced with the needle, the needle will not cause serious damage to the skin, and the needle can be prevented from being damaged, so the needle can be used effectively for a long time. [0002] In addition, each needle used in the present invention is formed with a polygonal cross-section of at least six sides instead of a circular cross-section, so that ...

Problems solved by technology

[0006] However, the above method of applying or spraying nutrients such as vitamin C or peptides on the skin has a problem in that 99.7% of the applied or sprayed nutrients cannot pass through the stratum corneum, the outermost layer of the skin, but remain On the skin and eventually disappears, only 0.3% of the applied or sprayed nutrients penetrate the dermis, so this method is less effective

[0015] Furthermore, it is nearly impossible to securely or closely fit the discs against each other so that the discs do not move undesirably, which makes conventional skin stimulators ineffective in stimulating the skin and the tips of the needles may be damaged, additionally , the tip of the damaged needle can also cause serious damage to the skin tissue

[0016] In addition, the needles used in conventional skin stimulators are thin and long needles with a circular cross section, so when the skin is punctured with the needle, the needle passes through the pain point of the human body, thereby causing the user to feel pain
