What is Class 4 Laser Therapy?

Class 4 laser therapy stimulates the body's natural healing processes using multiple wavelengths that penetrate from the skin’s surface to deep muscle tissue. This process, called photobiomodulation (PBM), enhances cellular energy (ATP production), reducing pain, inflammation, and promoting tissue regeneration. Unlike industrial lasers, Class 4 lasers are safe when used correctly. Sessions feel warm and soothing, similar to a spa treatment, with minimal side effects. Protective eyewear is required.

Benefits of Class 4 Laser Therapy

Class 4 laser therapy offers a gentle yet effective treatment for muscle and joint pain, providing relief from spasms and discomfort. Beyond pain relief, it stimulates cellular healing by increasing ATP production, reducing inflammation, promoting tissue regeneration, and improving nerve function and bone repair.

For sports injuries, laser therapy speeds up recovery, while for chronic conditions like arthritis, it provides ongoing pain management. It also benefits the surrounding tissue by enhancing cell regeneration.

Since injuries like sprains, arthritis, and tendonitis often cause tenderness, a gentler approach is preferred—Class 4 laser therapy delivers this while kickstarting the body’s repair process. Many patients notice improvement in the days following treatment.

Misconceptions About Class 4 Lasers

Some people associate lasers with cutting or burning, but Class 4 therapy lasers are much gentler. Unlike beauty treatments like laser hair removal, which damages hair follicles, this therapy stimulates healing without harming tissues. While the warmth builds up, it remains a comfortable experience, and any excessive heat can be adjusted by the technician.

Conditions Treated by Class 4 Laser Therapy

Class 4 laser therapy is effective for both short-term injuries and chronic conditions, including:

• Back, neck, and shoulder pain
• Joint pain, including tendonitis and bursitis
• Arthritis
• Sports injuries
• Sprained ankles and muscles
• Plantar fasciitis

What to Expect in a Session

Treatments last 15–20 minutes. You’ll wear safety glasses, and the laser’s intensity varies based on the condition. Some relief may be felt immediately, but multiple sessions (6–12) are often needed. Daily sessions can speed recovery, though weekly treatments are recommended to maintain healing progress.
