What is LED (Light Emitting Diode)?
It is the abbreviation of Light Emitting Diode, a semiconductor that can emit light of a specific color (wavelength). It was originally developed for the space mission of NASA (NASA) to cultivate plants in the air station. After studying its various properties and effects, it was finally concluded that the use of LEDs can reachfor the purpose of skin beautification. This has attracted high attention in the beauty industry, and most beauty salons now use this cutting-edge technology. Its biggest advantage is skin-friendly, painless, and no side effects, and it can be used for beauty care on the human body. The FDA (Food and Drug Administration) of the United States has even recognized its safety when used on the human body.
For human beings, light is indispensable
Speaking of light alone, the world is actually filled with all kinds of light. Among them, there are lights that are harmful to the human body, and LEDs can select specific wavelengths for them to make them emit light.
For example, the well-known ultraviolet light contained in sunlight can affect the skin. However, LEDs do not contain all UV rays and only select specific wavelengths that are good for the skin to make them glow. Moreover, the LED colored light mask beauty instrument itself is for the purpose of beauty, and it strictly selects LEDs with high brightness and high output power.
About the 4-wavelength LED used in the LED colored light mask beauty instrument
[Visible Light]
Blue (blue) LED: wavelength 460nm
Yellow (yellow) LED: wavelength 590nm
Red (red) LED: wavelength 640nm
[Invisible Rays]
Infrared ray: LED colored light mask beauty instrument uses near-infrared ray (note: the color of LED is colorless and transparent)
Moreover, the LED itself is small in size and long in life, and basically does not generate heat, so the power consumption rate is extremely low, and it is now receiving strong attention in all walks of life.
At the beauty exhibitions in recent years, there are constantly new products developed by using LEDs, and beauty salons are also constantly introducing technologies that use LED irradiation to achieve beauty care. The promotion of this technology in Europe and the United States is even worse. Using the most cutting-edge and safest LED for light beauty treatment is also very popular in salons.
LED is extremely safe
Using LEDs for beauty care that is absolutely safe, painless to the human body, and has no side effects is expected to be more used in the beauty scene in the future. .
About the bad effect of blue light on eye health and the safety of LED color light mask beauty instrument
1. Regarding the transmittance (permeability) of blue light and the opacity when eyes are closed
The LED color light mask beauty instrument is equipped with LEDs that are different from the white LEDs used in lighting fixtures and backlights. LED colored light mask beauty instrument uses a combination of high output power LEDs with specific wavelengths such as infrared light, red, yellow, blue, etc. Various wavelengths (colors) are uniquely integrated into one design. In the nursing procedure, the light transmittance is particularly important. The luminous color of the LED is closely related to the transmittance (permeability) of the skin and eyelids. Infrared light, red, and yellow have higher light transmittance in turn, but blue light basically penetrates Can't see through the eyelids.
For this matter, you can refer to the paper on eyelid light transmittance written by the University of California (Moseley MJら "Light transmission through the human eyelid: in vivo measurement." Ophthalmic Physiol Opt. 1988;8(2):229-30.)【 The light transmittance of the eyelid is 0.3% for blue; 0.3% for green; 5.6% for red].
That is to say, the light transmittance (permeability) of blue light is 19 times lower than that of red light, and 99.7% of blue light can be intercepted as long as the eyes are closed. LED colored light mask beauty instrumentThe LEDs equipped in the beauty instrument include infrared rays, all of which are wide-angle scattered light, and the use is also within the safe output power range. The program setting is also a program setting so that it will not become a single wavelength [only blue light]. When you feel dazzling, close the pupils, fully considering the program setting of eye health.
2. About the special protective glasses and blue light transmittance of LED color light mask beauty instrument
The special protective glasses included in the LED color light mask beauty instrument have the ability to weaken the 460nm blue LED light to 1/166 performance. 99.4% of the blue light can be blocked by the special goggles of the LED color light mask beauty instrument, which is to reduce glare, and the anti-rotation performance for blue light is also very high.
3. How to use the LED color light mask beauty instrument more safely
■Be sure to close your eyes when using
Close your eyes to block 99.7% of blue light. Even if you look directly at the light of the LED color light mask beauty instrument at the moment of pressing the button, it will not harm the health of the eyes. However, it is possible to temporarily feel that the surroundings are dark after seeing the dazzling light. The purpose is to try to avoid looking directly.
99.7% of blue light can be blocked by closing eyes as mentioned in 1 above.
Please wear protective glasses correctly. Among the programs of the LED color light mask beauty instrument, there are programs that require wearing protective glasses. When using this program, please wear protective glasses and close your eyes tightly.
