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

Traffic signal therapy utilizes a particular natural wavelength of light for therapeutic advantages, both medical and cosmetic. It is a combination of light-emitting diode (LED) that releases infrared light and heat.

Skin Specialist Lindsey Zubritsky, MD, describes that there is a spectrum– varying from ultraviolet (UV) rays and infrared (things we can’t see) to visible light– when it pertains to wavelengths of light (colors of the rainbow). Red light therapy makes use of low wavelengths of red light as a treatment because, at this specific wavelength, it is thought about bio-active in people cells and can directly and specifically affect and improve cellular function.

( It’s important to note that this specific 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.).

Red light 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 vital proteins live. Traffic signal photons are taken in by our cells and converted to energy. This energy produced can then promote the production of elastin, collagen, and adenosine triphosphate (ATP), which develops more energy for your cells to use. It increases oxygenation to your skin and improves flow while also fixing damaged tissue; this causes enhanced skin texture from increased collagen production and oxygenation.

Red light also has the distinct capability to decrease swelling and germs, and even deal with pre-cancerous sores states Zubritsky.
