MLS Class IV Laser vs. Red Light Therapy: What’s the Difference—and Why It Matters for Your Recovery

At the Foot and Ankle Center of Iowa, our commitment to delivering state of the art, patient-centered care means investing in the most advanced technologies available for healing and pain relief. One area of confusion we frequently address with patients is the difference between red light therapy and the MLS Class IV Laser system that we proudly offer at our clinic.

While both modalities use forms of light for therapeutic benefit, they are not created equal. Understanding the distinction is vital—especially when you're dealing with deep tissue pain or injury and are seeking proven, high-level results.

What Is Red Light Therapy?

Red light therapy, also known as Low-Level Light Therapy (LLLT) or photobiomodulation (PBM), utilizes visible red or near-infrared light in the 600–700 nanometer (nm) range. It’s primarily used to:

• Stimulate superficial skin cell activity

• Promote mild tissue healing

• Reduce localized inflammation

• Support hair growth and skin rejuvenation

Penetration Depth: Red light therapy typically penetrates just 5–10 millimeters into the skin—roughly the thickness of 10 stacked sheets of paper. While beneficial for surface-level conditions, it falls short for more complex, deep musculoskeletal problems.

MLS Class IV Laser Therapy: A New Standard for Deep Healing

The MLS (Multiwave Locked System) Class IV Laser is a high-powered therapeutic laser that goes far beyond the capabilities of red light therapy. It uses synchronized dual wavelengths (808 nm and 905 nm) to reach tissues up to 4–5 centimeters deep—about the depth of a golf tee.

This dual-wavelength approach achieves two things simultaneously:

• 808 nm (continuous emission): Reduces inflammation and improves blood flow.

• 905 nm (pulsed emission): Rapidly decreases pain signals in nerves.

Together, these wavelengths create a synergistic effect for deep tissue regeneration and long-lasting pain relief—without medication or invasive procedures.

Common Uses at Foot and Ankle Center of Iowa Include:

• Chronic joint pain and arthritis

• Neuropathy

• Achilles tendinopathy

• Plantar fasciitis

• Post-surgical recovery

• Sports-related soft tissue injuries

Why This Matters—Especially for Active Lifestyles

MLS Class IV Laser Therapy is not just for elite athletes, but it is trusted by them. From the NFL to Olympic training centers, Class IV lasers are being used to accelerate recovery, reduce downtime, and keep high-performing individuals at their best. These lasers are favored for their ability to promote rapid, deep healing—a critical factor for anyone facing soft tissue injuries or chronic pain.

While red light therapy might help with surface skin healing, it simply doesn’t have the depth, power, or therapeutic range to address conditions involving tendons, ligaments, or nerve pain.

A Clear Difference in Quality and Results

At the Foot and Ankle Center of Iowa, we have chosen MLS Class IV Laser Therapy because it offers:

• Superior depth of tissue penetration

• Scientifically validated healing mechanisms

• Real, lasting outcomes for chronic and acute conditions

This technology represents the highest quality in laser healing and is an integral part of our commitment to innovative, patient-focused foot and ankle care.
