How Does Red Light Therapy Work?

Red light therapy stimulates the mitochondria, often called the "powerhouses" of the cell, enhancing their energy production. This boost helps cells function more efficiently, potentially supporting improved repair, reduced inflammation, increased collagen production, and enhanced blood circulation.

The Science Behind Red Light Therapy


  • Step 1

    Mitochondria are the cell’s “energy plants.” Intense training or injury can cause chronic inflammation that damages mitochondria, reducing energy production. This leads to a buildup of waste, slowing healing and extending pain.

  • Step 2

    Scientists have discovered that at low-level wavelengths, red light stimulates mitochondrial activity. Once activated, mitochondria produce more energy—supporting cellular healing, reducing pain, and decreasing inflammation, according to studies.

  • Step 3

    In as little as 10 minutes, athletes may notice improved joint mobility. With regular use, red light therapy can help support injury prevention by speeding up recovery from intense training and sports activity.

Scientifically Proven

Supported By More Than 3,000 Clinical Studies

Thousands of clinical studies demonstrate that red light therapy improves recovery times, enhances muscle repair, reduces inflammation, and increases mobility - benefits now available through NovaLab devices.

The Science


  • Photobiomodulation for knee osteoarthritis: A models-based dosimetry study

    In this study, researchers discuss optimal angle of light transmission and placement to reach both sides of the patella.

  • Evaluation of the therapeutic effect of low level laser in controlling back pain

    Significant improvement in spinal pain, function, range of motions and tenderness.

  • Effect of Near-Infrared Light Emitting Diodes on Nerve Regeneration

    In this study, LED Irradiation improved nerve regeneration and increased antixidation induced by LEDs may be conducive to nerve regeneration.

FAQ's


When should I start seeing benefits from Red Light & Infrared Therapy?

With consistent use—typically 10 minutes or more per session, several times a week—many users begin to notice benefits within 2 to 4 weeks. Results may vary depending on your goals (e.g., pain relief, skin improvement, or recovery), but regular treatments are key to lasting results.

How is Red Light Therapy different from a heating pad?

Unlike heating pads, which offer surface-level warmth for temporary relief, red light therapy penetrates deeper into tissues to stimulate cellular activity. This light energy enhances circulation, supports cellular repair, and promotes long-term healing—offering more than just comfort, but real therapeutic benefits.

Is Red Light Therapy Safe to Use at Home?

Yes, red light therapy is safe for home use when used as directed. Our devices are built with medical-grade, non-toxic materials and meet the highest safety standards. Backed by over 3,000 clinical studies, red light therapy is a non-invasive, drug-free treatment with no known long-term negative side effects.

Here are a few safety considerations to keep in mind:

  • Mild redness or irritation can occur, especially with sensitive skin or overuse. Always follow the recommended session times.
  • If your skin feels dry after use, a gentle moisturizer can help.
  • Slight redness or mild discomfort may occur as part of the body’s natural healing response.

When used properly, red light therapy is a safe and effective tool to support healing, reduce pain, and improve overall wellness from the comfort of your home.

What is the difference between red light and infrared wavelengths?

The main difference lies in how deep they penetrate the body—and what they target:

🔴 Red Light (600–700 nm)


Visible to the human eye

Primarily absorbed by the skin’s surface layers

Best for:

  • Skin rejuvenation
  • Wound healing
  • Reducing Fines
  • Boosting Collagen production

🔥 Near-Infrared (NIR) Light (700–1100 nm)


Invisible to the human eye

Penetrates deeper into muscles, joints, and tissues


Best for:

  • Muscle Recovery
  • Joint Pain
  • Inflammation reduction
  • Improving Circulation

Summary:


Red Light=Surface Level healing and skin benefits

Infrared Lighte=Tissue repair and pain relief

Many devices combine both wavelengths for comprehensive therapy—supporting skin health and deeper recovery.
