The healing results of light therapy are nothing brand-new– it was first utilized in the late 1800s to treat skin tuberculosis (TB), and NASA utilized it in the 1980s to grow plants in outer space.

What is Red Light Therapy, and How Does It Work?

Traffic signal therapy utilizes a specific natural wavelength of light for therapeutic benefits, both medical and cosmetic. It is a mix of light-emitting diode (LED) that gives off infrared light and heat.

Dermatologist Lindsey Zubritsky, MD, discusses that there is a spectrum– ranging from ultraviolet (UV) rays and infrared (things we can’t see) to noticeable light– when it pertains to wavelengths of light (colors of the rainbow). Traffic signal therapy utilizes low wavelengths of traffic signal as a treatment due to the fact that, at this particular wavelength, it is thought about bio-active in people cells and can straight and particularly impact and improve cellular function.

( It’s important to keep in mind that this particular kind of light is not the same as UV rays from the sun or what is found in tanning beds, and there is no increased threat of skin cancer or UV damage.).

Traffic signal can permeate our leading layer of skin and into the deep levels of skin called the dermis. This is where our collagen, elastin, and other essential proteins reside. Traffic signal photons are absorbed by our cells and converted to energy. This energy produced can then promote the production of collagen, adenosine, and elastin triphosphate (ATP), which develops more energy for your cells to use. It increases oxygenation to your skin and enhances flow while also repairing damaged tissue; this results in enhanced skin texture from increased collagen production and oxygenation.

Red light likewise has the distinct ability to reduce swelling and bacteria, and even deal with pre-cancerous lesions says Zubritsky.
