Photizo Pain Relief is a hand-held, rechargeable LED light-therapy device that emits red and infrared light at specific wavelengths and frequencies to activate the body’s own pain control and increase blood circulation. At the touch of a single button, Photizo Pain Relief administers a pre-programmed treatment with an effective dose of 30 seconds. Photizo’s Personal Range units use both red and infrared light. Red light is very beneficial in treating problems close to the surface such as wounds, cuts, scars, trigger points and acupuncture points, and is particularly effective in treating infections. Infrared light is effective for bones, joints, deep muscles, bursa, etc. Although both red and infrared wavelengths penetrate to different depths and affect tissues differently, their therapeutic effects are similar.
