Your skin has the ability to absorb infrared light and use it as a source of energy to stimulate cellular regeneration. Infrared LED light therapy, first researched by NASA for use in the U.S. Space Program, can reverse and control the visible signs of aging and help you look years younger without harsh chemical treatments or invasive surgical procedures. Dramatic tightening of the skin, smoothing of wrinkles and rough spots, disappearing blemishes, softening of redness, and shrinking of pore size can be achieved with this natural light treatment. In addition, the unit can be used to effectively treat minor muscle and joint aches, sprains, back pain, muscle spasms, the pain and stiffness associated with arthritis, and more.
