Frequently Asked Questions

Have you got questions? We've got answers!

What is Red Light Therapy and how does it work?

Red Light Therapy (RLT) uses specific wavelengths of light that penetrate deep into the tissues. 

This light stimulates the mitochondria in your cells to produce more energy (ATP), which reduces inflammation, supports repair, and helps restore joint mobility.

Is Red Light Therapy safe?

Yes. Clinical research has shown that RLT is non-invasive, drug-free, and safe for long-term use. 

It does not damage the skin or tissues and is well tolerated by patients of all ages.

How is KneeFix Pro different from other red light devices?

Many devices use incorrect wavelengths or insufficient power, which limits results. 

KneeFix Pro is engineered using clinical research to deliver the most effective wavelengths, combined with soothing heat and compression, ensuring faster relief and long-term benefits.

How often should I use KneeFix Pro?

For best results, we recommend 10–15 minutes per session, 4–5 times per week. The benefits of red light therapy are cumulative, meaning results improve with consistent use over time.

What results can I expect and how quickly?

Many users feel initial relief from stiffness and discomfort within the first few sessions. 

With regular use, improvements in mobility, reduced inflammation, and long-term joint comfort typically appear within 2–4 weeks.

Can it help with osteoarthritis and chronic knee pain?

Yes, multiple studies have shown that red and near-infrared light therapy can reduce inflammation, improve cartilage resilience, and relieve pain in osteoarthritis. 

KneeFix Pro is designed specifically to target these issues effectively.

Can KneeFix Pro be used on other joints?

Absolutely. While optimized for the knee, it can also be applied to other problem areas such as the hip, shoulder, ankle, or elbow, providing the same therapeutic effects.
