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

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

Skin Doctor Lindsey Zubritsky, MD, discusses that there is a spectrum– ranging from ultraviolet (UV) rays and infrared (things we can’t see) to visible light– when it concerns wavelengths of light (colors of the rainbow). Red light therapy utilizes low wavelengths of red light as a treatment because, at this particular wavelength, it is considered bio-active in human beings cells and can directly and specifically impact and improve cellular function.

( It’s crucial to keep in mind that this particular type of light is not the like UV rays from the sun or what is discovered in tanning beds, and there is no increased danger of skin cancer or UV damage.).

Red light can permeate our top layer of skin and into the deep levels of skin called the dermis. This is where our collagen, elastin, and other necessary proteins live. Traffic signal photons are absorbed by our cells and transformed to energy. This energy produced can then promote the production of adenosine, collagen, and elastin triphosphate (ATP), which develops more energy for your cells to utilize. It increases oxygenation to your skin and enhances flow while also fixing harmed tissue; this causes enhanced skin texture from increased collagen production and oxygenation.

Traffic signal also has the unique capability to decrease swelling and germs, and even deal with pre-cancerous lesions says Zubritsky.
