Description

System and method for skin care using wavelength tunable LED {System and Method for Skin Care using wavelength tunable LED}

The present invention relates to a skin care system and method using a variable wavelength LED that improves skin by irradiating LED wavelengths suitable for a user's skin using a mask using LED wavelengths and a smartphone application (app) that measures the user's skin condition. will be.

In general, human aging appears in various forms, but among them, skin aging is often accompanied by skin diseases that are difficult to overlook. The fact that the aging of the skin is revealed starts with slowing down the progress for each individual, and rather, various efforts are made to make the skin age younger.

Currently, the occurrence of skin troubles caused by various environmental factors is common, and in addition to this, the fact that each individual's genetic characteristics are due to skin troubles has also been proven as a scientific basis.

Based on various and in-depth analyzes of genetic information, it has already been proven that specific genetic traits and genetic information have a significant effect on human skin aging or skin troubles.

Furthermore, it is known that environmental pollution and the resulting allergy, stress, etc. affect skin troubles. In other words, the development of industry has brought convenience and improved living standards to humans, but due to human stress, environmental pollution, and ecosystem destruction from fierce competition in the global era, more and more problems are emerging and new diseases are emerging. There is a situation.

Phototherapy for the treatment of skin diseases uses the principle of promoting biochemical reactions in the skin by irradiating light to the skin using various light sources such as sunlight, laser, fluorescent lamps, and ultraviolet lamps to selectively regenerate or regenerate skin tissue. It is an optical medical technology that treats damaged skin through destruction.

Unlike high-power lasers, the LED light source can irradiate a large area of disease with appropriate light output, and the skin treatment technology using the LED light source is similar to the principle in which sunlight is converted into plant cells through chlorophyll in plants. It induces a photo-biochemical reaction between skin cells by irradiating LED light source.

Phototherapy using such an LED light source is based on the fact that photons of the LED light source are absorbed by chromospheres or photoreceptors in cell tissues and promote metabolic activities of cells.

The light absorbed by cells increases the synthesis of ROS and ATP in cell tissues, and cells exposed to red light and near-infrared light release NO (Nitric Oxide). Light of a wavelength selected at an appropriate time and period is absorbed by photoreceptors such as cytochrome C oxidase in cells, which photodegrades inhibitory NO, promotes enzyme activation, and metabolizes mitochondria and generates ATP (Adenosine Triphosphate) promotes

This causes proteins such as hemoglobin and myoglobin to release additional NO, which results in a series of intracellular biochemical reactions.

As a result, LED light irradiation to cells activates the overall metabolic activity of cells and plays a large role in cell regeneration and rehabilitation.

In addition, LED light irradiation can promote the production of collagen and elastin in the skin, suppress the occurrence of wrinkles, and make the skin moist and elastic.

In addition, LED light irradiation exerts a significant effect on the treatment of skin diseases. For example, when LED light, particularly blue LED light is irradiated on a skin area where acne occurs, bacteria that cause acne are eliminated and inflammation is relieved, thereby improving the overall condition of the skin.

In order to improve the skin as described above, various cosmetics and beauty devices have been developed and distributed on the market.

The operation of the light source unit 102 of the mask 100 is controlled by the program (102) for driving the light source unit 102 (S40).

At this time, the operation of the light source unit 102 of the mask 100 operates at a predefined irradiation time, wavelength range, and lighting position according to the generated use mode.

And the operation of the light source unit 102 of the mask 100 is performed through the user's control and selection through the power button unit 201 and the selection button unit 202 of the controller 200. Therefore, operations such as irradiation time, wavelength range, and lighting position can be changed by user's control and selection through the power button unit 201 and the selection button unit 202 of the controller 200.
