Red light therapy works by exposing the skin to low concentrations of red or near-infrared light. These wavelengths of light penetrate the skin and are absorbed by the mitochondria in the cells, the powerhouses of the cell.
This absorption stimulates the production of adenosine triphosphate (ATP), the energy-carrying molecule in cells. Increased ATP production improves cellular function and promotes healing and rejuvenation.
In addition, red light therapy stimulates the production of collagen, an important protein for skin health and elasticity.
Red light therapy can also increase blood circulation and reduce inflammation, contributing to its therapeutic effects.
