Description

Skin beauty device {skin beauty device}

The present invention relates to a portable skin beauty device, and more particularly, to prevent safety accidents such as burns on the skin of a subject by irradiating the troubled skin with LED rays having a specific wavelength, which are involved in skin regeneration and sterilization. It is to prevent and at the same time sterilize the skin, and improve the skin beauty effect through light stimulation that soothes and regenerates the skin through the improvement of blood flow in the skin.

Acne, one of the representative skin diseases, appears mainly in men and women before and after puberty, and is caused by hormones that begin to be secreted during puberty stimulate the sebaceous glands to enlarge the sebaceous glands and promote the secretion of sebum. Acne is an inflammatory disease of the sebaceous gland of the hair, and a comedone composed of sebum, keratin and microorganisms is formed due to blockage of the hair follicle.

In particular, if the inflammation of the sebaceous gland attached to the hair follicle increases, it can cause serious skin damage, and it is difficult to cure it and is likely to develop into a more serious situation.

Usually, there are many cases of squeezing acne with fingernails, but this is unsanitary, and the germs are transferred and fester, and only a part of the acne is removed, and a large part remains, causing inflammation to expand, causing sequelae such as scarring.

Therefore, it is desirable to treat acne through a surgical method (treatment), etc., and several acne treatment devices used for such a surgical method have been developed. For example, as a conventional technique for removing acne, an acne treatment device using a mechanical treatment method that sucks acne, such as a tool for squeezing acne simply configured in a cylindrical or ring shape, or a syringe-shaped device, has been developed.

In addition, recently, through prior art, such as Patent Registration No. 10-1083061 or Publication Patent Publication No. 10-2014-0031858, an acne treatment device having a light source unit emitting light such as LED has been developed.

In other words, an acne treatment device has been developed that relieves symptoms of acne by facilitating drainage of infection without clogging hair follicles by light, or prevents the spread of inflammation by killing various germs.

The prior art as described above can show effects such as skin beauty or purulent acne relief by calming, regenerating, or sterilizing damaged skin by interviewing a light source unit emitting light near the skin to irradiate the light beam, but in particular, purulent acne relief or When used for treatment purposes, the number of light emitting diodes constituting the light source unit emitting light is very small, so it can be pointed out that the efficiency of skin beauty or acne treatment by light irradiation is significantly lowered, and furthermore, it can be pointed out that Since the high heat generated from infrared LEDs and visible light LEDs having a specific wavelength constituting the light source unit is directly transmitted to the skin, skin damage due to burns, especially purulent acne, aggravates inflammation when used for a long time.

The present invention makes it a technical problem to provide a skin beauty device using light rays that can be efficiently expanded and irradiated to the skin using a small number of complexly arranged LEDs having a specific wavelength.

In addition, the present invention makes it a technical problem to help skin care while preventing skin damage caused by high heat by emitting high heat generated from a plurality of LEDs constituting the light source unit to the outside of the device.
