3. How does red light therapy work?

The innovations of science have made a surprisingly simple technology widely available. When red light at 633nm is absorbed at a cellular level by the mitochondria a simulation of intracellular energy transfer occurs. The production of this energy means cell vitality and permeability is increased overall. Production of new collagen, and increased turnover of collagen and elastin occurs during this process, ensuring that the fibers within skin are firm. Scientific studies have also shown that cells grow 150-200% faster upon exposure to certain light wavelengths.
