What is Red Light Therapy?

Before diving into the costs, let's quickly recap what red light therapy is. Red light therapy (RLT) uses low-level wavelengths of red light to treat various skin issues, pain, and other health concerns. This non-invasive treatment can be administered in clinics, spas, or even at home with the right equipment.

Understanding the Costs

The cost of red light therapy can vary significantly depending on several factors. Here's a closer look at the different options:

Professional Treatments

  1. Clinic or Spa Sessions: These are typically priced per session. On average, you can expect to pay anywhere from $25 to $85 per session. High-end clinics might charge more, especially if they offer advanced equipment and added amenities.

  2. Packages: Many clinics and spas offer packages that lower the per-session cost. For example, a package of 10 sessions might range from $200 to $600, providing a significant discount compared to paying for individual sessions.

At-Home Devices

  1. Handheld Devices: These are more affordable and portable, usually costing between $50 and $300. They're great for targeting small areas.

  2. Full-Body Panels: These can be quite an investment, ranging from $500 to over $2,000. However, they offer the convenience of home treatment and can be more economical in the long run if used frequently.

Is Red Light Therapy Worth the Investment?

Now that we've covered the costs, the big question remains: is red light therapy worth it? Here are some factors to consider:

Proven Benefits

  1. Skin Health: Red light therapy has been shown to improve skin conditions like acne, rosacea, and eczema. It can also reduce wrinkles and promote collagen production, making your skin look younger and healthier.

  2. Pain Relief: Many users report significant pain relief from conditions like arthritis, muscle strains, and joint pain. This can be a game-changer for those struggling with chronic pain.

  3. Mental Health: Studies suggest that red light therapy can improve mood and reduce symptoms of depression and anxiety, thanks to its ability to enhance mitochondrial function and boost serotonin levels.

Long-Term Value

Investing in a high-quality at-home device might seem expensive initially, but it can save you money over time compared to regular clinic visits. Plus, the convenience of treating yourself at home is unmatched.

Factors to Consider Before Investing

  1. Frequency of Use: If you plan to use red light therapy regularly, investing in an at-home device could be more cost-effective. However, if you only need occasional treatments, paying per session at a clinic might be better.

  2. Personal Goals: Consider what you want to achieve with red light therapy. If your goals are mainly aesthetic, a smaller, more affordable device might suffice. For broader health benefits, a more comprehensive setup might be necessary.

  3. Budget: Be realistic about what you can afford. There are effective options at various price points, so you don’t have to break the bank to experience the benefits of red light therapy.

Conclusion

In conclusion, red light therapy offers a range of health and wellness benefits that can justify the investment for many people. Whether opting for professional treatments or purchasing an at-home device, the potential improvements in skin health, pain relief, and overall well-being can make it worth the cost. Assess your needs, budget, and treatment goals to determine the best approach for you.

We Wanted to Find the Best Red Light Therapy Device to Help With Pain. Here’s Why We Can’t Recommend Any.

Published October 22,

Using a wand or scary-looking mask to bathe your face in red light is all the rage for helping to make skin look and feel better. But another use for red light therapy is also gaining traction: treating pain.

The therapy involves using devices with laser lights or light-emitting diodes (LEDs) to deliver specific wavelengths of light that penetrate the skin surface into deeper tissues to affect cellular function—a process known as photobiomodulation. While scientists aren’t sure exactly how light relieves pain, research suggests that it may stimulate cell regeneration, reduce pain signals, and calm inflammation.

Devices for home use ranging from wraps to wands—some of them costing thousands of dollars—claim to alleviate pain for everything from an arthritic knee to an aching back. But there’s reason to be dubious.

Physician and researcher Dr. Mohab Ibrahim, who directs the Chronic Pain Management Clinic at the University of Arizona’s College of Medicine in Tucson, Arizona, has researched different forms of light therapy for pain. As a scientist, he maintains some skepticism. “Researchers still do not have a full understanding of the biological mechanisms for how red light therapy works,” he said. “Or even who is a good candidate.”

But as a clinician, Ibrahim acknowledges that people in pain often have limited options. “Here is a therapy that is low risk, relatively affordable, and has the potential to work,” he said. When patients ask about red light therapy, he encourages them to give it a go.

SUNRECIPE supply professional and honest service.

Unfortunately, like all the pain experts I consulted, Ibrahim wasn’t able to recommend specific devices for home use. There are no evidence-based guidelines for what type of device and settings may work best against different forms of pain, he pointed out. And neither the US Food and Drug Administration nor any independent testing organization has reviewed red light therapy devices to ensure that they’re effective at relieving pain.

That leaves us without solid grounds for judging the best red light devices. So instead, we’ll give you the lowdown on the evidence and what medical experts say. And if you’re still interested in trying a red light device, we’ll provide some general advice on what to look for—and what to avoid.

The evidence is mixed

Despite thousands of studies, research still lacks definitive answers on whether red light therapy alleviates pain. Some studies show a benefit; others do not.

To truly show that red light therapy works, we would need evidence from large clinical trials comparing the treatment with a placebo (a fake device, for example), said Dr. Praveen Arany, an associate professor of oral biology at the University of Buffalo School of Dental Medicine and former president of the World Association for Photobiomodulation Therapy (WALT), a nonprofit organization supporting research, education, and clinical applications for light therapy.

Unfortunately, Arany said, researchers haven’t yet found funding for those expensive large-scale studies.

One major problem with the research available, said Ibrahim, is that the study methods vary widely—for example, by the wavelength and intensity of the light, whether it’s pulsed or steady, and how long it’s applied. Another issue is that many studies use professional devices with laser lights rather than LEDs, which give off less focused light and are the mainstay of home products because they are safer and often cheaper than lasers.

Timothy Demchak, a professor in the department of applied medicine and rehabilitation at Indiana State University, is convinced that red light therapy is a safe, effective way to alleviate pain. He said that many of his physical therapy patients have benefited from treatment with the laser devices that he uses in his practice.

In a review of red light research published in the European Journal of Physical and Rehabilitation Medicine, Demchak and colleagues reported evidence to suggest that therapy using LEDs or lasers helped against some types of muscle and joint pain, such as neck pain, osteoarthritis, and fibromyalgia.

But the group didn’t find strong evidence that red light therapy worked against some other common aches, such as lower back pain. The field desperately needs more rigorous research, Demchak said. Many of the existing studies are lower quality—they may involve too few patients, for example, or lack a comparison group that didn’t receive the red light treatment.

Nonetheless, under the right circumstances, he contends that red light therapy can be “very, very effective.” It comes down to figuring out the optimum treatment protocol for each type of pain, he said.

Those protocols don’t yet exist. WALT has developed guidelines for using red light to prevent oral mucositis (mouth ulcers that can be a side effect of cancer treatment). But the organization has had a harder time reaching a consensus for how to treat common afflictions such as back and neck pain, said Arany.

While different researchers may claim that specific devices and settings are effective, he said, as of yet they haven’t been able to provide a satisfying scientific explanation for how and why the device may work in those conditions. Without that information, he says, it’s hard to generalize results to all types of products and patients.

“There are so many devices,” said Arany. “People are just not agreeing on universal guidelines.”

The medical establishment is skeptical

Due to the lack of consistent evidence supporting red light therapy, as well as the tremendous variation in how it’s implemented, most health insurers don’t cover treatments performed in a doctor’s office. And major medical organizations haven’t issued guidelines for using red light therapy to treat pain.

Although some providers such as Demchak use red light therapy in their practices, the American Physical Therapy Association doesn’t recognize it as an effective form of therapy. And a spokesperson for the Arthritis Foundation told me that they “were unaware of any clinicians or researchers the Arthritis Foundation works with who give red light therapy much regard.”

If you still want to try a red light therapy device

If you’re in pain, check with your doctor before trying to treat yourself at home. “Pain is a warning sign,” said pain expert Mohab Ibrahim. “There might be something benign or it might be something serious that needs to be addressed.”

Even if the source of your pain has been diagnosed, you should still check with your doctor before trying red light therapy. In particular, Ibrahim cautions against using red light on areas where there is a wound, rash, or other skin condition without first getting your doctor’s okay.

If, after all those caveats, you are still interested in trying out a red light device at home, the experts we consulted offered some general advice. We link to top-selling devices on Amazon as examples of the different styles and configurations we mention, but we have not tested any of these devices and are not recommending them.

What to look for

  • It’s tailored to the source of your pain. Red light therapy devices come in various configurations, including rectangular panels, wraps, wands, and gloves. The intensity of the light falls off rapidly the further away you are from the source. With that in mind, Praveen Arany, a light-therapy expert, recommends choosing a product that conforms to the aching body part so that the light is against your skin.

    Examples include knee-shaped wraps, belts for your back or shoulders, and gloves for your hands. If your body is larger or smaller than average, check the product’s measurements to make sure that it will fit you. Wands and panels allow you to direct the light exactly where it hurts, but keep in mind that you may have to prop the device up or hold it in place for several minutes if it doesn’t come with a base or stand.
  • It offers multiple wavelengths. What’s commonly referred to as “red light therapy” typically uses wavelengths from the red, near-infrared, and infrared part of the light spectrum, about 600 nanometers to 1,000 nanometers, with longer wavelengths penetrating more deeply. There are no widely accepted guidelines for what wavelength to use for specific types of pain, so figuring out which setting works best for you may take some trial and error.
  • It includes features for safety and convenience. While research suggests that red light therapy is safe, Arany is concerned that prolonged exposure could negate any benefits and possibly even damage tissues. A timer or auto-shutoff feature can ensure that you don’t exceed the manufacturer’s recommended treatment times. Other nice-to-have features include a remote control and the ability to operate from rechargeable batteries so that you are not tethered to a wall socket.
  • It isn’t too expensive. Researchers would need more clinical evidence to meaningfully link price to quality, Ibrahim said. Given that a $5,000 red-light device may not be more effective than a $100 model, he recommends that patients start with a less expensive product.

    You may be able to save by buying a device using pre-tax dollars from a health savings account or flexible spending account. Check your plan for details.

What to watch out for

  • It claims to be FDA-approved. Although you may run across the term “FDA-approved” in articles and ads, no red light devices are actually approved for treating pain, according to FDA spokesperson Carly Pflaum. Generally, the FDA regulates these devices as Class II medical devices, meaning that they don’t potentially pose a serious risk to consumers. Unlike Class III devices like pacemakers or breast implants, products in the Class II category typically aren’t required to go through the FDA’s rigorous approval process, which uses evidence from clinical studies to determine that the device works for the intended use and is safe.

    Red light therapy devices may be FDA-registered or FDA-listed, indicating that a company has notified the agency about a product and the manufacturing location, but it doesn’t mean that the FDA has actually evaluated the product. Companies may also go through the process for FDA clearance, meaning that the agency has reviewed information about the device and concluded that it’s substantially equivalent to others on the market.

    FDA clearance provides some reassurance about safety and effectiveness, since presumably equivalent products haven’t raised red flags. However, clearance doesn’t necessarily mean that treatment with the product has been proven to relieve pain. You can check whether a device is cleared in the FDA’s database.
  • It makes promises that are too good to be true. Red light therapy won’t cure arthritis or eliminate chronic pain. Even in studies that show it helps, the benefit is often modest.

How to use your device safely

With red light therapy, more isn’t better, so never exceed the manufacturer’s instructions for how long or how often to use the device, advises Arany. The treatment isn’t supposed to heat the tissues, so if the area you’re treating starts to feel warm, stop immediately, he said.

Many devices come with safety goggles or dark glasses. Although the intensity and wavelength of light used in home devices is likely not harmful to the eyes, Demchak advises using eye protection out of an abundance of caution, especially if you’re using the device near your eyes.
