How Does Natural Red & Near Infrared Light Work

NASA had this same question when it commissioned a company called QDI to conduct research on red light therapy in 1993. After it was proven that the technology could activate plant growth in space, contracts were awarded to investigate the medical application of light-emitting diodes (LEDs)—with a special focus on how LED photon energy transfers to human cells stimulating activity and growth.

This preliminary research demonstrated the effective health benefits of a specific wavelength of red light: 660 nanometers (nm). What began as a way to limit the bone and muscle loss of astronauts has led to hundreds of peer-reviewed clinical studies documenting a wide variety of benefits from various wavelengths within the red and near infrared (invisible) spectrums.

Currently, the FDA has approved red and near infrared light therapy for the treatment of joint pain and arthritis, inflammation, edema, tissue repair, exercise performance, reduction of wrinkles, pigmentation, scars, acne and flaccid skin.  Many other off label conditions are awaiting approval, such as hairloss, rosacea, eczema, vitiligo, wound healing, herpes/cold sores, alzheimer's, cancer and much, much more.

At Red Light Life we use only FDA approved, medical-grade quality LED systems using the power of light harnessed at optimal wave lengths, power densities and dosages based on over 400 published clinical research outcomes. 

Red and NIR Light Therapy has a wide range of applications of use in dermatology, especially in indications where stimulation of healing, reduction of inflammation, reduction of cell death and skin rejuvenation are required. The application of Red and Near Infrared Light to disorders of pigmentation may work both ways by producing both repigmentation of vitiligo, and depigmentation of hyperpigmented lesions depending on the dosimetric parameters. The introduction of LED array-based devices versus laser has simplified the application to large areas of skin.
