Low Level Laser Therapy: How It Works and What It Treats

If you’re looking for non-invasive, drug-free options for pain relief, tissue repair, or injury recovery in Vancouver, Low Level Laser Therapy (LLLT)—also known as Class IV Cold Laser Therapy—is gaining traction as a powerful therapeutic tool. We’re seeing more and more patients benefit from this advanced modality. But what exactly is it, and how does it work?

What Is Low Level Laser Therapy (LLLT)?

Low Level Laser Therapy is a treatment that uses specific wavelengths of light to interact with tissue and help accelerate the body’s natural healing processes. Unlike surgical lasers, cold lasers do not generate heat and are completely non-invasive. Class IV lasers are among the most powerful in the cold laser category, enabling deeper tissue penetration for more significant therapeutic effects.

How Does Class IV Cold Laser Therapy Work?

The Class IV laser emits light energy that penetrates the skin and is absorbed by the mitochondria in your cells—the energy powerhouse of your body. This process, called photobiomodulation, increases cellular energy (ATP), boosts circulation, reduces inflammation, and stimulates tissue regeneration.

Think of it as charging your cells' batteries, helping them work more efficiently and repair damaged tissue faster.

What Can Class IV Laser Therapy Treat?

Laser therapy is used to relieve pain, reduce inflammation, and speed up healing in a wide variety of conditions. At our  clinic, some of the most common issues we treat with LLLT include:

• Chronic pain (e.g., back pain, neck pain)
  
• Joint injuries (e.g., knee, shoulder, elbow)
  
• Arthritis and osteoarthritis
  
• Tendonitis (e.g., Achilles, tennis elbow)
  
• Plantar fasciitis
  
• Sports injuries
  
• Post-surgical healing
  
• TMJ dysfunction
  
• Mastitis

How many treatments will I need?

Treatment frequency depends on the condition, severity, and your body’s response. Some patients experience relief after just 1–2 sessions, while chronic conditions may require 6–12 sessions for optimal results.

Most sessions take between 15 to 30 minutes, depending on the area being treated.
