Cells in the skin and supporting tissue absorb specific wave lengths between 590 and 950 nanometers. Our cells/tissue convert this light energy into “fuel” that is used to increase cellular metabolism. Research by the National Aeronautics and Space Administration (NASA) has shown that light therapy could increase cellular metabolism by 250 percent. While the NASA study focused on healing injuries, the effect of light therapy on skin is exactly the same. The increased cellular activity stimulates formation of new collagen and elastin — the building blocks of healthy skin.
