You've probably heard a lot about LED light therapy in recent years, but you may have wondered why it's so popular or how it even works?
LED technology was originally developed by NASA and tested on plants to see if they could grow in space. When scientists performed their experiments they discovered that LED light worked on a cellular level to stimulate growth and kickstart cell metabolism.
When they tested it on humans, the results were even more impressive. Even in a low oxygen environment, LED was shown to speed up wound healing. This was quite significant and the benefits didn't end there.
Why Is LED Light So Beneficial For The Skin?
LED light is a source of energy for skin in a similar way that sunlight is a source of energy for plants. Different wavelengths of light penetrate the skin layers at specific levels and have profoundly different physiological effects.
As we age, our cells become sluggish. What LED essentially does is it fires up the cells by increasing the amount of available energy, also known as ATP.
When the cells are exposed to LED light, they begin to behave like a younger and more vibrant version of themselves. This means that they not only can heal and repair more rapidly, but also turnover much quicker.
LED teaches the skin how to function better and supports its own healing process in a way that even more invasive treatments can't replicate. The effects of one LED session can last for up to 72 hours.
When used consistently and over a period of time, LED light can help rebuild and re-educate the skin, making it healthier, more resilient and more vibrant without any negative side effects. This makes it one of the most powerful anti-aging tools available today.
