Red light therapy is a treatment that involves shining low-levels of red and near-infrared light on your skin to improve your cells’ health. This can lead to numerous health benefits like anti-aging, hair growth, pain relief, and more!
Unfortunately, the “red light” doesn’t mean you can just sit under a red light bulb and reap the benefits. While wavelengths of light between 620-750 nanometers (nm) are considered red, the optimal wavelengths are between 610-625 nm (red) and 660-690 nm (deep red). This combo, when used with near-infrared light (750-1000 nm), can penetrate not only your surface-level skin cells but also your skin tissue.
If you haven’t heard before, you might know it by one of its other names:
Low-level laser therapy (LLLT)
Cold laser therapy
Low-power laser therapy (LPLT)
Light-emitting diode therapy (LEDT)
While shooting laser beams at yourself might sound painful, it is entirely painless. Since the treatment only uses low-powered light that doesn’t generate any heat, you don’t feel a thing while the light works its magic. Unlike the high-powered lasers used by doctors to kill cancer cells – those are quite painful!
While there is still some controversy around the practice, the growing list of research studies has yet to find any adverse side effects. In fact, these scientific studies increasingly prove the vast potential of it application in areas such as anti-aging, healing, and immunity.
Many NASA astronauts, Navy SEALs, and cancer patients have used RLT to improve wound healing, relieve pain, and reduce inflammation.
In the past, if you wanted to experience the benefits, you had to go to specialized salons, clinics, and spas. Now, you can get started with red light therapy in the comfort of your own home for a fraction of the cost.
