Red Light Therapy Knowledge Hub
Everything you want to know about red light therapy, photobiomodulation (PBM), wavelengths, dosage, usage, and choosing a device — clearly explained and without exaggerated claims.
Start Here
Red light therapy is scientifically studied for various applications. The quality of evidence varies by purpose, device, and protocol. Therefore, we look beyond just nanometers or wattage.
Our Red Light Solutions
Compare devices by application, size, wavelengths, portability, and usage. Higher wattage or a larger device does not automatically mean better results.

How to Evaluate a Red Light Device?
- Start with your goal and the body area.
- Check the actual specified wavelengths.
- Look at irradiance, distance, and treatment time when this data is available.
- Assess the total dosage and the prescribed protocol.
- Compare comfort and ease of use: a device you use consistently may be more practical than a larger device that goes unused.
- Always follow product-specific safety information.
Our Principles
Kenza Beauty Lab distinguishes between scientific research into PBM and what a specific consumer device can demonstrate. We avoid medical result guarantees and communicate uncertainty when the evidence is limited or protocol-dependent.
Research into PBM covers many different applications. Positive results in one research area cannot automatically be translated to every device or application.
Frequently Asked Basic Questions
Is red light therapy the same as infrared?
No. Visible red light and near-infrared are different parts of the spectrum. Infrared heat is also a different application than PBM.
Is 660nm automatically better than 850nm?
No. Suitability depends on the goal, device parameters, dosage, and protocol.
Is more wattage better?
Not automatically. Wattage alone does not tell you how much light energy a body zone receives.
Can red light therapy guarantee results?
No. Results vary by person, application, device, and protocol.
