Light Therapy has been used in the medical profession for over 60 years. It was first discovered for NASA by  Dr. Harry Whelan  to assist the astronauts while in space.  It has since been used to promote collagen for healing, to repair blindness and aid in healing cancer. Photo dynamic LED (light emmiting diodes) differs from other heat activitating treatments such as intense light, radio wave frequencies (ultra sound) and lasers in that it does not induce a thermal injury to force the activity of collagen.  This treatment assist the cellular metabolic process, which in turn activates the cells to produce more ATP.  ATP is the fuel our skin cells need for healing and collagen production. LED light is less concentrated than the pinpoint of light in a laser and the light is dispersed more evenly and it can be used for a longer period to stimulate the growth of collagen with side effects to the DNA. Treatments that induce heat and create a thermal injury force the stem cell to repeat itself.  Dr. Hayflick, a professor of cell biology, was able to determine that the stem cell cannot undergo such forced heat inflammation without having to repair itself and that the DNA can only repair up to 50 times without turning in the direction of cancer.  His studies have been recorded and termed "The Hayflick Limit".  Leds are much safer and as they never burn the skin and they assist the body with near infrared and infrared LED light energy to produce up to 150 times more collagen. This technology helps to prolong the lifespan of your DNA, softens and removes your wrinkles., and It rebuilds the lipid barrier to defend against pollution.  LED's thicken our muscles while repairing the vascular structure supporting the whole internal network and bringing more nutrition to  your skin.
