Research on Healing with Red LED Light

Nearly 50 years ago, European scientists discovered that certain monochromatic single-wavelength light beams had excellent therapeutic effects on afflicted cell tissue through a process called photostimulation.

Various wavelengths in the red and infrared spectra were tested. The two most beneficial methods of producing the desired beams were the laser and light-emitting diode (LED), as neither introduced other wavelengths or impurities. Hospitals and clinics began using “soft” or “cold” lasers and LEDs to stimulate damaged cell tissue, demonstrating proven results in pain relief, accelerated wound healing, improved skin conditions, wrinkle removal and acupuncture point stimulation.

Laser equipment, however, is expensive and approved for use only by licensed physicians and health professionals. LED products, on the other hand, offer 90% of the photostimulation benefits of a cold laser — at only 10% of the price. Their life expectancy is 20 times longer – 100,000 hours of use. Even more exciting is the fact that LED is completely harmless, with absolutely no side effects. This allows a LED unit to be used on a much wider range of problems than a cold laser.
