Frequently Asked Questions

What is the difference? arrow icon

The statement you’re referring to is included for compliance and regulatory reasons. It simply clarifies that the specific research studies we mention were not conducted using our brand-name devices. However, it’s important to note that the technology used in those studies is the same type of red and near-infrared light therapy our devices deliver.

In fact, our devices are often more advanced than those originally used in the studies, incorporating the latest in LED technology, improved wavelengths, and optimized power output for enhanced results. So while we must state that the exact branded devices used in the research were not ours, the therapeutic principles and functionality are the same, if not superior in many cases.

How long after a surgery do we have to wait to use the RLT stand or belt? arrow icon

After surgery, it’s generally best to wait at least 2 to 4 weeks before using red light therapy devices like a stand or belt on or near the surgical area. The exact timing depends on the type of surgery and how well you’re healing. For minor procedures, about 2 weeks may be sufficient, while major or internal surgeries often require a wait of 4 weeks or more. For eye surgeries such as cataract removal, red light therapy should only be resumed after clearance from your ophthalmologist, typically not before 3 to 4 weeks post-op. Although red light supports healing by stimulating cellular activity, using it too soon can overstimulate fresh wounds or interfere with recovery. Always consult your healthcare provider before reintroducing red light therapy after surgery.

Does red light help osteoarthritis? arrow icon

Red light therapy can be highly beneficial for osteoarthritis, helping to reduce pain, inflammation, and joint stiffness. It works by improving cellular energy production, enhancing circulation, and reducing oxidative stress in the affected area. Wavelengths like 660nm (red) and 850nm (near-infrared) are particularly effective, as they penetrate the tissue to stimulate repair and reduce inflammation. Clinical studies have shown that regular use can improve range of motion, decrease morning stiffness, and reduce reliance on pain medication. For best results, it’s recommended to use the light for 10–20 minutes per session, 3–5 times a week, with the device positioned about 6–12 inches from the joint. Over time, consistent use may support cartilage health and provide lasting relief without the side effects of conventional medications. Even the Arthritis Foundation acknowledges photobiomodulation as a helpful complementary therapy.

Is it safe to look at the lights when it is turned on? arrow icon

We suggest wearing an eye patch or at least keeping your eyes closed when red and NIR light is exposed directly to your face.

Are red light therapy products you have FDA approved and is there one specifically for eyes? arrow icon

Yes, our RedLife devices are FDA approved. However, we don’t have an “eye-specific” device, but the panels work perfectly for an eye and full-body treatment.

Although it’s been 10 years since open heart surgery, and I currently have multiple stents, can RLT still be used and heal arteries and scar tissue? arrow icon

Yes, ​​red Light Therapy (RLT) can still be beneficial for you, even 10 years after open heart surgery and with multiple stents. RLT may help promote tissue repair, reduce inflammation, and relieve pain. For instance, a randomized controlled study found that low-level laser therapy applied after coronary artery bypass graft (CABG) surgery decreased cardiac cellular damage and accelerated cardiac tissue repair, potentially lowering postoperative disability and bed rest periods. ​Application of Low-Level Laser Therapy Following Coronary Artery Bypass Grafting (CABG) Surgery Additionally, RLT has been shown to reduce scar tissue formation in cardiac tissue following myocardial infarction. A study demonstrated that low-energy laser treatment significantly decreased the size of non-contracting scar tissue in the heart, reducing infarct size by more than 50%. ​Laser Treatment Reduces Scarring After Heart Attack Furthermore, RLT has been reported to promote tissue repair and reduce inflammation around surgical implants, such as stents, suggesting potential benefits in enhancing healing and reducing complications.​

How deep does the light penetrate the body? arrow icon

For red light at 630nm to 660nm: In general, red light wavelengths in the range of 630 to 660 nm have been shown to penetrate relatively deeply into the skin, reaching depths of several millimeters. However, the exact depth of penetration can vary depending on the factors mentioned above. For example, darker skin types with higher melanin content may absorb red light more strongly, limiting its penetration depth. In terms of biological effects, red light therapy is thought to stimulate mitochondrial function, promote blood flow, and enhance cellular metabolism. These effects are generally believed to be most pronounced in the superficial layers of the skin and underlying tissues. For NIR light at 810-850nm: Near-infrared light, including 850nm, has been shown to penetrate deeper into tissues than visible light wavelengths. However, the exact depth of penetration can vary depending on the factors mentioned above. For example, darker skin types with higher melanin content may absorb near-infrared light more strongly, limiting its penetration depth. In terms of biological effects, near-infrared light therapy is thought to promote blood flow, enhance mitochondrial function, and have anti-inflammatory effects. These effects are generally believed to be more pronounced in deeper tissues compared to visible light wavelengths. Additionally, it’s worth mentioning that near-infrared light, including 850nm, is often used in various medical and therapeutic applications, such as wound healing, pain relief, and skin rejuvenation.

Are there any side effects to using red light therapy? arrow icon

Red light therapy is generally considered safe, non-invasive, and free from significant side effects when used as directed. It is a natural treatment that has been shown to reduce pain and inflammation without the risks associated with prescription medications or invasive procedures.

Should I remove clothing during red light therapy sessions? arrow icon

For optimal results, it's recommended to expose the targeted area directly to the light as clothing can block light penetration and reduce treatment efficacy.

Should I remove jewellery during red light therapy sessions? arrow icon

Yes, it's generally recommended to remove jewelry while using red light therapy. Here’s why:

  1. Heat Retention – Metal jewelry can absorb and retain heat, which might lead to discomfort or even minor burns during prolonged exposure.
  2. Reflection & Interference – Metals can reflect or absorb some of the light wavelengths, potentially reducing the effectiveness of the therapy in certain areas.
  3. Skin Contact Issues – Some metals may react with light and heat, causing skin irritation or discoloration.
Is red light therapy safe to use for pregnant women? arrow icon

While red light therapy is generally safe, it’s best to consult with a healthcare provider before using it during pregnancy, especially if applying it to the abdomen or lower body.

Can I use red light therapy on areas with tattoos? arrow icon

While red light therapy is generally safe, it's recommended to monitor the tattooed area for any adverse reactions during initial sessions, as individual responses can vary.

Is red light therapy suitable for pets? arrow icon

Red light therapy has been used for animals; however, it's essential to consult with a veterinarian before using it on pets to ensure their safety.
