Injury and Wound Healing

630nm Research

  • 630 nm LED Boosts Tendon Cell Growth for Injury Healing

    Lab tests on human tendon cells showed that 20 minutes of 630 nm LED light made the cells multiply faster and move better, which could help speed up recovery from tendon injuries like strains or tears by encouraging natural repair.

  • 630 nm LED Speeds Healing in Diabetic Wound Model

    In rats with wounds similar to diabetic foot ulcers, 630 nm LED light promoted faster healing by boosting cell growth, new blood vessels, collagen, and reducing inflammation, with big improvements seen in just 5–10 days.

  • 630 nm LED Accelerates Wound Healing in Rats

    Using a portable LED device at around 630 nm on cuts in rats for 30 minutes daily over 2 weeks, the stronger dose closed wounds faster, grew more collagen and blood vessels, making it a safe option for treating skin injuries.

660nm Research

  • 660 nm LED Stimulates Cell Energy for Wound Healing

    In skin cells essential for wound repair, 660 nm LED light created a lasting increase in energy production (ATP) over 24 hours, helping cells stay active and potentially accelerating the healing process by supporting better cellular function.

  • 660 nm LED Promotes Diabetic Wound Cell Proliferation

    Lab experiments demonstrated that 660 nm LED light enhanced the growth and migration of cells from diabetic wounds, activating key healing pathways to improve tissue repair and offering hope for faster recovery in diabetic patients.

810nm Research

  • 808 nm LED Accelerates Burn Wound Healing in Rats

    In rats with serious burns, daily 10-minute treatments with 808 nm LED light (practical overlap with 810nm) for a week lowered inflammation, encouraged new cell and collagen growth, and helped the wounds close faster, working just as well as a laser for quicker recovery.

830nm Research

  • 830 nm LED (and Similar Wavelengths) Promotes Wound Healing Like Lasers

    A review of studies showed that LED therapy at wavelengths like 830 nm increases fibroblast growth, collagen production, and new blood vessels, speeding up wound closure and tissue repair in both lab and animal models, with effects similar to lasers for safe, non-invasive injury healing.

  • 830 nm LED Enhances Diabetic Wound Healing in Rats

    In diabetic rats with skin wounds, 830 nm LED therapy over 14 days boosted collagen production, new blood vessels, and tissue growth, leading to faster wound closure and better healing compared to controls.

  • 830 nm LED Low-Level Therapy Heals Various Wounds in Patients

    In a preliminary study on patients with different wounds (like pressure ulcers and burns), 830 nm LED treatments achieved full healing, controlled infection and pain, with treatment times varying by wound condition, proving safe and effective for clinical use.

  • 830 nm LED Promotes Cutaneous Wound Healing

    A review highlighted that 830 nm near-infrared LED light is highly effective for healing impaired skin wounds by reducing inflammation, boosting cell proliferation, collagen, and blood vessels, based on multiple lab and animal studies.

850nm Research

  • 850 nm LED Enhances Bone, Cartilage, and Tendon Repair

    In rats after tooth extraction, 850 nm LED increased bone cells and remodeling; for cartilage in arthritic models, it boosted collagen and prevented breakdown; for tendons, it improved cell viability and migration, all supporting faster healing of connective tissue injuries.

  • Multi-Wavelength LED (Including 880 nm NIR) for Wound Healing After Laser Treatment

    In a trial with 25 people after skin laser resurfacing, a device with blue, red, and 880 nm near-infrared LED (practical overlap with 850nm) showed a trend for faster healing on the treated side, with reduced redness and crusting, though not statistically significant, and safe for home use (note: 880 nm is close to 850 nm and shares similar benefits in NIR light therapy for tissue repair).

  • 635–850 nm LED Promotes Wound Healing Phases

    Histological reviews of LED therapy from 635 to 850 nm showed increased inflammatory cells, blood vessels, fibroblasts, and collagen in early healing, shortening inflammation and enhancing tissue repair for better wound recovery.

Did you know near-infrared (NIR) light is beyond our vision range? That’s why you won’t see our 810nm, 830nm, and 850nm LEDs — even though they’re working just as powerfully as the visible 630nm and 660nm ones
