A Revolution in Healing
Discover why modern LED-based light therapy is a safer, more effective, and practical alternative to traditional lasers for a vast array of conditions.
Enhanced Safety
LEDs produce virtually no heat, eliminating the risk of tissue damage. They emit a diffuse light, making them safe for the eyes without needing protective eyewear.
Wider Treatment Area
The wider aperture of LED probes allows for the treatment of larger body areas like the back and neck, making sessions faster and more efficient.
Practical & Portable
Lightweight, robust, and often battery-operated, LED devices are perfect for both clinical and home use, offering unparalleled convenience.
Cost-Effective
LED technology is significantly more affordable than traditional lasers, making advanced light therapy accessible to more people.
A Versatile Treatment for Numerous Conditions
By enhancing cellular energy and promoting natural healing, Red light is effective across a wide range of applications.

Cellular Response to Light Therapy
How Light Therapy Works
Understanding the science behind photobiomodulation therapy
LIGHT ABSORPTION
Red and near-infrared wavelengths (630-850 nm) penetrate the skin and are absorbed by cellular photoreceptors.
CELLULAR STIMULATION
The light energy boosts mitochondrial ATP production, triggering a cascade of beneficial cellular effects.
HEALING RESPONSE
Inflammation drops, circulation rises and tissue repairs faster, delivering natural pain relief.
Key Therapeutic Benefits
REDUCED INFLAMMATION
Decreases inflammatory markers and cytokines, reducing swelling and associated pain.
IMPROVED CIRCULATION
Increases blood flow and formation of new capillaries for better oxygen delivery.
ACCELERATED REPAIR
Stimulates collagen production and cell proliferation for faster tissue and wound healing.
PAIN RELIEF
Reduces nerve sensitivity and increases endorphin production for natural pain relief.
Real results from Photizo light therapy
KNEE OSTEOARTHRITIS
"After years of knee pain and limited mobility, I was skeptical. After just 4 weeks of consistent treatment, I’ve experienced significant pain reduction and can now walk much further without discomfort."
Treatment: 90 seconds, twice daily for 4 weeks
SPORTS INJURY RECOVERY
"As a competitive runner, muscle injuries can derail my training. After a grade 2 calf strain, I was back to light running in 10 days using Photizo—far faster than the expected 3–4 weeks."
Treatment: 60 seconds, 3x daily for 10 days
POST-SURGERY RECOVERY
"My surgeon was amazed at how quickly my incision healed. The physical therapist noted I achieved range-of-motion goals weeks ahead of the typical timeline."
Treatment: 60 seconds, twice daily for 3 weeks

Light Therapy Glossary
Key terms to understand photobiomodulation therapy
Photobiomodulation (PBM)
The scientific term for light therapy that uses red and near-infrared wavelengths to stimulate cellular function, reduce inflammation, and promote healing.
Wavelength
Measured in nanometers (nm), wavelength determines the color of light and its penetration depth. Red light (630-660nm) and near-infrared (810-850nm) are most therapeutic.
Joules
The unit of energy delivered during treatment. Optimal therapeutic dose typically ranges from 3-15 joules per cm² depending on the condition being treated.
Power Density
Measured in mW/cm², this indicates the intensity of light delivered to tissues. Effective therapeutic ranges are typically 30-100 mW/cm².
Chromophores
Light-sensitive molecules in cells that absorb photons. Cytochrome c oxidase in mitochondria is the primary chromophore in red/NIR light therapy.
Mitochondria
The "powerhouse" of cells that produce ATP energy. These organelles are primary targets of red and near-infrared light therapy.
ATP (Adenosine Triphosphate)
The primary energy carrier in cells. Light therapy increases ATP production, providing more energy for cellular repair and regeneration.
Nitric Oxide
A signaling molecule released during light therapy that improves blood flow, oxygen delivery, and triggers various healing mechanisms.
Cytokines
Signaling proteins involved in inflammation. Light therapy helps regulate pro-inflammatory and anti-inflammatory cytokines to promote healing.
Biphasic Dose Response
The principle that light therapy follows a "sweet spot" pattern—too little energy has no effect, while too much can inhibit benefits.
