![]() There are now over 4,000 peer-reviewed studies on the topic (from organizations such as NASA and the US Military). Unlike the high-powered lasers used by doctors to kill cancer cells – those are quite painful!įirst developed in 1967, RLT has since undergone intense scientific scrutiny. 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. While shooting laser beams at yourself might sound painful, RLT is entirely painless. If you haven’t heard of RLT before, you might know it by one of its other names: This combo, when used with near-infrared light, can penetrate not only your surface-level skin cells but also your skin tissue. 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). Unfortunately, the “red light” in RLT doesn’t mean you can just sit under a red light bulb and reap the benefits. This can lead to numerous health benefits like anti-aging, hair growth, pain relief, and more! 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. While I’ll go into detail about the features of each, here’s a TL DR table for those in a hurry to get started. I’ve also included a list of some of the highest-rated red light therapy devices. Here’s what the science says about red light therapy, so you know what’s legit and what’s not. So, while there are documented health benefits like wrinkle reduction, there’s still not much evidence to support some of the claims a few RLT companies are making. The science surrounding RLT, while extremely promising, is still in its preliminary phases. But, there are also some things to be wary of. You almost have to wonder: Is this one of those too-good-to-be-true miracle cures we see on the internet?Īccording to the thousands of research studies on red light therapy (RLT), there’s a lot to be excited about. When I first encountered red light therapy, I was amazed… and a bit skeptical.Ī device that seems to have a never-ending list of benefits from anti-aging to hair growth? And it’s something you can use in the comfort of your own home? Plus, no side effects or harsh chemicals?
