How red & near-infrared light works
What the research says is happening.
Reduced inflammation
Red and near-infrared light have direct anti-inflammatory effects. Published research shows these wavelengths reduce key inflammatory markers in tissue, supporting an environment where the body's natural repair processes can work more efficiently.
Boosted cellular energy
Your cells convert red and near-infrared light into cellular energy through the mitochondria. Published research has directly measured increased energy production in human tissue following light therapy. More cellular energy means cells can maintain, repair, and regenerate more effectively.
Supported gut bacteria balance
Published research shows abdominal red and near-infrared light can shift the balance of gut bacteria in a healthier direction. A 2025 systematic review found increased production of short-chain fatty acids, the compounds that fuel colon cells and support immune function.
Nerve function support
Red and near-infrared light have been studied for their effects on nerve tissue. Research shows these wavelengths support nerve regeneration and increase antioxidation levels, which may help maintain healthy nerve signaling in the back, hips, and lower extremities.
Improved blood circulation
Red and near-infrared light boost blood flow to treated areas, delivering more oxygen and nutrients to tissue that needs repair. Improved microcirculation supports the body's natural maintenance of muscles, joints, and digestive tissue.
Tissue repair support
Published research shows red and near-infrared light support connective tissue repair processes, helping cells in cartilage, muscle, and the gut lining produce more energy, build collagen, and maintain structural integrity.
Two things only CuraYou does
Why the Cura LaserFlex Ultra™ is built differently.
USP 01 · PENETRATION
Medical-grade lasers that reach deep tissue.
Standard at-home red light therapy belts use only LEDs, which scatter as they pass through skin and fat. The Cura LaserFlex Ultra™ combines 35 semiconductor lasers with 190 LEDs across four wavelengths. Lasers deliver coherent, focused light that penetrates deeper, reaching muscles, fascia, nerves, and gut tissue that LED-only devices cannot effectively access. This is the same class of laser technology used in clinical photobiomodulation research.
USP 02 · POWER
1,850 mW total irradiation power.
Irradiation power determines how much therapeutic light actually reaches your tissue. The Cura LaserFlex Ultra™ delivers 1,850 mW of total output across four precision wavelengths (630nm, 650nm, 808nm, and 940nm). Higher power means more photons reach the target tissue at the depth where they're needed, critical for areas like the lower back, abdomen, and hips where tissue depth is greatest.
One device, two paths to relief
What would you like to support?
Tap either option to see how the Cura LaserFlex Ultra™ helps.
The challenge
Why most at-home devices fall short for gut health.
Most gut and digestive discomfort stems from an imbalance in the gut's microbial community, combined with chronic inflammation in the gut lining. Standard approaches like dietary changes, probiotics, and supplements can help, but they don't address the cellular energy deficit and oxidative stress that make the gut lining vulnerable in the first place.
Red and near-infrared light therapy has been shown in published research to support gut bacteria balance, reduce inflammatory markers, and boost the cellular energy that gut tissue needs to maintain itself. But reaching the gut from outside the body requires light that can penetrate through skin and the abdominal wall, something LED-only devices struggle to deliver effectively.
The solution
Engineered for deep abdominal delivery.
The Cura LaserFlex Ultra™ combines medical-grade semiconductor lasers with high-output LEDs across four wavelengths specifically selected for deep tissue penetration. When placed on the abdomen, the laser component delivers coherent light capable of reaching gut tissue, something LED-only belts and panels cannot match.
Backed by published research and designed to be used hands-free in just 15 minutes per day, it offers a practical, drug-free approach to supporting gut health at the cellular level. Each device comes with a holistic treatment plan developed specifically for digestive wellness.
The challenge
Why back pain after 50 gets harder to manage.
Chronic back pain is rarely one thing. It involves inflammation in spinal joints, wear in the discs that cushion each vertebra, nerve compression, and muscle tension — often all at once. Standard pain management focuses on one pathway at a time: anti-inflammatories block one signal, nerve blocks target another, physical therapy addresses mobility. Each helps, but none changes the underlying cellular environment driving the pain.
Published research shows that red and near-infrared light therapy supports multiple biological pathways simultaneously — reducing inflammatory signaling, boosting cellular energy production, and supporting nerve function. A 2022 meta-analysis pooling 19 randomized controlled trials found consistently favorable results for laser therapy in chronic low back pain.
The solution
Deep-penetrating relief for the whole back.
The Cura LaserFlex Ultra™ was built for exactly this challenge. Its 35 medical-grade lasers deliver coherent light deep into the muscles, joints, and spinal structures where chronic back pain originates — tissue that LED-only devices and panels cannot effectively reach.
The 19-inch belt wraps around the lower back, hips, or abdomen hands-free, delivering 1,850 mW of therapeutic light in just 15 minutes. No positioning a handheld device. No clinic appointments. Each unit includes a treatment plan designed specifically for chronic pain management.

The science, in plain language
Four wavelengths. How they work.
630 NM · RED LED
650 NM · RED LASER
Targets surface tissue and drives cellular energy production.
Red light at 630nm and 650nm is absorbed by the mitochondria, the energy centers inside every cell. This increases cellular energy production (ATP), which research shows is the foundational driver of tissue repair, inflammation control, and healthy cell function. The 650nm laser component delivers this energy as a coherent beam that penetrates more efficiently than LED light alone.
Red wavelengths support the body's natural inflammatory response. Published studies show red light reduces key inflammatory markers while increasing anti-inflammatory signals, shifting the balance away from chronic inflammation and toward repair.
808 NM · NIR LASER
940 NM · NIR LED
Reaches deep tissue that red light alone cannot access.
Near-infrared wavelengths pass through skin, fat, and muscle to reach deeper structures such as spinal joints, nerve roots, fascia, and gut tissue. The 808nm laser delivers focused near-infrared energy deep into tissue where chronic pain and gut dysfunction originate.
Published research shows near-infrared light supports nerve function, boosts blood flow through nitric oxide release, and enhances the body's natural tissue repair processes. The 940nm LED extends coverage across a broader treatment area, ensuring comprehensive deep-tissue delivery.

Questions, answered honestly
Before you order.
Why does laser technology matter for this type of device?▼
Lasers deliver coherent, focused light that maintains its intensity as it passes through tissue. LEDs scatter as they penetrate, losing energy at depth. For areas like the lower back and abdomen, where the target tissue sits beneath layers of skin, fat, and muscle, laser technology delivers more therapeutic photons where they're needed. The Cura LaserFlex Ultra™ was designed specifically for use on the back and abdomen, which is why it includes 35 semiconductor lasers alongside 190 LEDs.
How long until I notice a difference?▼
Individual responses vary. Published clinical research on photobiomodulation for back pain typically reports measurable improvements within four weeks of consistent daily use. Some users report noticing changes sooner. The included treatment plan provides structured guidance for the first three months.
Can I use this if I'm already taking medication or doing physical therapy?▼
Red and near-infrared light therapy does not interact with medications and can be used alongside physical therapy, exercise, and standard medical care. Published research has studied it as both a standalone approach and in combination with exercise programs, with combination approaches often producing the best outcomes.
Is it safe for daily use?▼
Red and near-infrared light therapy has an established safety profile across decades of clinical research and hundreds of published trials. The Cura LaserFlex Ultra™ is a FDA Class II medical device and ISO certified. The device delivers energy within the therapeutic window established by published research.
What is the maximum waist size for this device?▼
The belt measures 19 inches × 6 inches. The elastic band can be 43 inches long, so the instrument can be used if the waist circumference is generally less than 59 inches.
Can I use my HSA or FSA funds?▼
Yes. The Cura LaserFlex Ultra™ is HSA/FSA eligible as an FDA Class II medical device.
