The Science Behind Red Light Therapy

Understanding photobiomodulation at the cellular level

How Red Light Therapy Works

Red light therapy (photobiomodulation) uses specific wavelengths of light (630-850nm) to stimulate cellular energy production through mitochondrial activation. The primary mechanism involves cytochrome c oxidase (CCO), the terminal enzyme in mitochondrial respiration.

Frequently Asked Questions

Click any question to reveal the answer

How long does it take to see results?

Results vary by application: Acute effects like pain relief may be immediate to 2-4 weeks. Hair growth typically shows results at 8-12 weeks with peak results at 16-26 weeks. Skin rejuvenation usually requires 8-12 weeks of consistent use. Most conditions benefit from an initial intensive phase (daily treatments) followed by maintenance (2-3x weekly).

What's the difference between red light and near-infrared?

Red light (630-660nm) is visible and penetrates 8-10mm deep, ideal for skin, superficial wounds, and hair follicles. Near-infrared (810-850nm) is invisible and penetrates 30-50mm deep, better for deep tissue, muscles, joints, and bones. Many devices combine both for comprehensive treatment.

Do I need eye protection?

Eye protection is mandatory for devices exceeding 20 mW/cm² when treating near the face. While some research suggests red light may benefit eyes, direct exposure to high-power devices can cause temporary eye strain or discomfort. Use the provided goggles or keep eyes closed during facial treatments.
