Does Red-Light Therapy Work? (2025)
Even if the glowing mask scares your family, red-light therapy can rejuvenate skin and aid in muscle repair.
How Can I Access Red-Light Therapy?
Red-light therapy has long been used by athletes and wellness professionals to boost recovery and reduce oxidative stress.
These days, it’s fast becoming the norm at the local gym and wellness spa too.
You’ll probably be able to find red-light therapy rooms or “red light stations” there, which make up part of a hot and cold contrast therapy circuit alongside cold plunges and saunas.
Benefits of Red-Light Therapy
Meanwhile, red-light therapy is noninvasive and uses specific wavelengths of visible red and near-infrared light to stimulate cellular activity and help them heal more efficiently.
“Red-light therapy is an umbrella term encompassing all red light frequencies on the spectrum, from the most basic visible LED to invisible near-infrared laser light,” says Graeme Glass, the aesthetic director at Lyma.
RLT has been shown to rejuvenate skin to improve the texture and tone, reduce wrinkles, and help with recovery, for example.
Factors to Consider
However, results are often gradual, and patience is key when using red-light therapy across the face and body.
When used as directed, red-light therapy is also considered low risk, but the main drawbacks are usually mild and temporary, such as warmth or slight skin redness if a session is too long or the device is held too close.
Consequently, research is expanding into neurological uses, such as traumatic brain injury and cognitive decline, where early findings are promising.
