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

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

Skin Specialist Lindsey Zubritsky, MD, explains 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 makes use of low wavelengths of red light as a treatment because, at this particular wavelength, it is thought about bio-active in people cells and can straight and specifically affect and enhance cellular function.

( It’s crucial to keep in mind that this particular kind of light is not the like UV rays from the sun or what is found in tanning beds, and there is no increased risk 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 essential proteins reside. Traffic signal photons are absorbed by our cells and transformed to energy. This energy produced can then promote the production of collagen, elastin, and adenosine triphosphate (ATP), which creates more energy for your cells to use. It increases oxygenation to your skin and improves flow while also fixing harmed tissue; this leads to improved skin texture from increased collagen production and oxygenation.

Red light likewise has the unique ability to reduce inflammation and germs, and even treat pre-cancerous sores says Zubritsky.
