What do you know about photofacial treatments?

When it comes to light therapy, more people think of its application in the medical field, such as laser therapy and weak laser treatment. But for the use in the field of beauty, few people know, even if they have heard of it, is also little known. Today, the next light editor will dissect the true nature of light therapy beauty Lushan.

As early as 2000, the National Aeronautics and Space Administration (NASA) found that through a specific spectrum of LED light source on the astronauts' muscles and bones for moderate irradiation, can accelerate wound healing. Later on, light waves were studied and it was found that different wavelengths of light could activate cellular activity to different degrees and speed up metabolism. Light therapy is the use of different wavelengths of red, yellow and blue light in visible light to improve the growth environment of skin cells and thus improve skin quality.

This type of phototherapy is a physical therapy that regulates the biological activity of cells by setting different wavelengths, combinations of wavelengths and duration of light to improve skin characteristics. In the United States, phototherapy has become widely recognised and is the beauty treatment of choice for many Hollywood actors and actresses.

At this stage, the main light source used in phototherapy is the relatively mature LED, several LED beads are placed in the phototherapy beauty device, through the light waves to stimulate cells, repair the skin.

LED is a point source of light, LED light therapy beauty instrument to point array placement, which is not conducive to the face of small parts of the uniform light, but also, LED light will be with the extension of the light time and warming, if there is no a perfect heat optimization design, light therapy beauty effect will be affected to some extent.

The OLEDs, which can also be used in light therapy, will not heat up with the extension of the light time and will not diminish the effect of light therapy. In addition, OLED is a surface light source, so that every small part of the face is evenly lit; its thinness and softness make it easier to produce light therapy and beauty devices, and the appearance is more varied.
